=Universcale Flash Application by Nikon=

toc Read here about a website sponsored by Nikon, called "Universcale."

=Overview= Universcale is a flash application that permits the user to manually zoom over all known scales of length. The application was designed by [|Business Architects Incorporated] (Japan, est. 1999), CEO Toru Hayashi, with illustrations rendered by [|Yoshida Yoriko] in 2005. The application was honored by a listing in New York's Museum of Modern Art "[|Design and the Elastic Mind]."

The application is one of the finest superscale distance scale comparisons ever created. The designers chose about one hundred objects of interest. These are portrayed in several ways. The first way is a cartoon outline on a length scale, so that objects can be compared in outline. The second portrayal is a detailed illustration, with text describing the item. Lastly, the detailed illustration may be flanked by a representative object smaller and larger, the two comparative objects shown in outline view. The three views facilitate discovery and comprehension of the different scales of length.

As with many superscale surveys, the user is not given any visual indication of the changing nature of space and behavior at the different scales, though the accompanying texts do atempt to descibe this variation.

=Introductory Text=

The text introducing Universcale:

This world in which we live. The universe that comprises our world. In order to better understand them, humans have assigned to them the concept of "size" so that they may be comprehended by all. Nevertheless, there are actually very few things that we can see with our eyes or feel with our own hands. Our curiosity brings us to use objects visible to the naked eye as yardsticks to identify those things invisible and to give them new units of measurement. We are now capable of comparing and ranking these entities. We have, in fact, been given an ‘infinite yardstick.’ By setting things up against this yardstick, observing and comparing them are we able to accurately identify their true forms. They are silent when merely observed, but spring to life when put to use in a unique, creative way. One thing we know for certain is that they are all around us in our close vicinity.

=Text for each scale=

Picometer
Unrevealed Potential.

At present, we are not able to realistically accept the scale of this unit into our daily lives. This size - known as the size of the nucleus of an atom - is,from a practical standpoint bundled up into the "sub-nano order,~ the general realm of the miniscule and microscopic.It thus unfortunately lacks any specific identity as yet, in terms of its function or worth. Quite simply, it is best described as the "premature 'prodigy' of potential~ -- although it is not in any way a fantasy that exists only in theory. Theories preceding a concept, as long as they are not mistaken, should lead the way for the realization of appropriate technology at lightning speed. In the not-so-distant future, the titles of "Industrial revolution of the 2lst century~" "infinite possibility that changed the history of mankind" will undoubtedly be attributed to the  and  picotech. Then, for what purpose should we utilize such phenomenal technical capabilities? The evolution of such technology shall test our intellect and creativity.

nanometer
A Familiar Microworld.

The term ~nano" always accompanies dreamlike catch phrases.Dramatic developments in various technologies have decidedly extended the world we can 'see,' inviting us into the ultra fine world of matter at the molecular and atomic level. We can now make minimal substances even smaller, or collect and transform them into a different material of any desired size or shape. One billionth is such an unimaginable, unrealistic smallness. What can this size be likened to? The ratio of the earth (1 meter) to a one yen coin (1 nanometer) is a commonly used example.Regardless, thanks to the microscope and in-depth probing,mastered the art of altering atomic configurations at will, manipulating, controlling, and generating  we have  them. In due time, all of our current conceptions regarding matter, such as quantity, quality, color and shape may be abolished.

Products developed on the nanometer scale are already being marketed as daily life consumables. Our growing interest is on how the nano will be applied to those products that are familiar to us and how it will relate to our lives in the future.

micrometer
The Microcosm under the Microscope

Each human is, without doubt, an independent being in this natural world. Humans form complex communities and are interlinked to many other life forms. Although we are prone to consider ourselves the smallest units of such a world, this notion is not quite accurate. Our bodies are made up of approximately 60 trillion cells, each of which is an aggregation of tens of millions of microbes, and each of these microbes in turn is loaded with genes. In other words, we ourselves are a community of microbes, and therefore we are microcosms which are repeatedly born and destroyed just like the universe.

Within our bodies, dramatic science fiction-like events are unfolding every day. The bacteria and viruses constitute intruders from the outer world, tackled by our various immunity defenses. Microscopic cells with ‘minds of their own’ are alive within us, such as the cells that spin out life by repeatedly dividing and multiplying, and the ‘misbehaving’ heretical cells that begin attacking others of their own kind.

millimeter
Limits of the Naked Eye

The human eye is a sensory organ possessing extremely precise and delicate capabilities.However, unlike certain creatures such as flies and bees, which possess superior visual perception, humans require certain extremely defined conditions - or more specifically, a limited range of wavelengths - for sight. The millimeter is the limit to our naked eye vision.Rulers are marked with millimeters as the smallest unit and as the objects become more minute, from hair to fleaswe lose our ability to perceive them. We regard anything beyond this limit as 'another world.' Up until the Industrial Revolution, the most precise unit used in measurement and in manufacturing was the millimeter. Recently, however, the progress of computer-based technology has allowed us to completely exceed this limit. Meanwhile, the things that we can measure with the naked eye are still what we trust and understand the most.

centimeter
Realm of the Palm We are generally intolerant of those ‘small things’ that are within the range visible to the naked eye. For example, in our daily urban life - with the exception of some pets - we tend to perceive most insects and small animals as annoying, unidentifiable, and unpleasant. Are insects beneficial or pests? Do we utilize them or eliminate them? Rarely are we so black and white about our position in a single area. Then, why?

While smallness fosters in us feelings of tenderness and kindness, at the same time it stimulates our desire for control and domination. The expressions "have in your hand" and "get hold of" are perfect examples. A small person shows his might to a smaller entity which he can control freely in the palm of his hand, and perhaps this is a consequence of his smallness. Recently, we have become increasingly fascinated with ‘function in the palm,’ and encounter various opportunities for our curiosity to be thus aroused. Our obsession with and enthusiasm for compact and highly functional products are an expression of our desire to control and dominate, as well as symbols of our individual styles.

meter
The Unit that Measures the World

The Convention of Meter, concluded in France in 1875, established a single-unit system to be shared and comparable on the international level. In place of the units of measurement using various parts of the body,such as length of the feet distance between fingers or other close-at-hand objects,or those established individuaUy within regional communitiesthere was approved a new common standard for the global community,based upon a value calculated from a giant object we all share alike, the Earth. The existence of a standardized, official value for size has given new meaning to our world.Today, we try to measure everything in the world and grasp its sizeby combining our own perception with these numerical values. These measurements stimulate in us awe for the longer, larger, higher and faster existence, as well as feelings of sympathy and tenderness towards the small and the ephemeral. The meter, the common standard of the global community, has given value to all entities serving as a bridge between this world, our practice and our imagination.

kilometer
A Realistic Grandeur

Units have redefined our world. In particular, we use numerical expressions of size and distance to evaluate the outcomes of various activities in the cultural and economic arenas. Not infrequently, these numbers have also symbolized power and success. Since accurately measured sizes afford an objective perception, they enable us to share common amazement. This could be the reason why we so desire to conquer the highest peak, construct the world's tallest building, or make a far journey to a place where no man has ever been. It may also be true that our competition for the limits and superiority has promoted the development of various technologies. These perceivable, ‘real’ sizes incite in us adoration and amazement.

light year
The Extremities of Space

The night sky full of stars that we see is actually an aggregation of light released from stars of differing ages in the distant past. In a single view, we are able to see light released at various moments, hundreds, or tens of thousands of years ago, without being the least concerned with the distance of each star. Because of the power of the constant and fastest entity, light, we can amuse ourselves by connecting the random arrays of the stars we see and attributing to them stories and relational meaning. Still, we find it difficult to grasp their actual distance and size, since the universe is just too extensive. We cannot for example, easily imagine the speed of light. Nor can we fathom the density of the external galaxies that are scattered about outer space, described by I.Asimov in an immensely fitting metaphor: "A single particle of sand in a large 32 km by 32 km room." Although various scholars have been speculating and studying the universe for ages and defining it through measurement the cosmos itself is continually growing and waning. tomorrow, we may find contrasting results or new discoveries. ether the countless stories of our imagination and the never-ending fascination of scholars.

=Items included in Universcale=

Below are the details on the items included in the Universcale flash application, with the text accompanying the item that is presented in the application

Universe
Universe (Outer limit of the universe) 13.7 billion light years In 2003, NASA announced that the universe is 13.7 billion years old, flat in shape, and will continue to expand forever, based on its observation of cosmic background radiation. The outer limit of the universe is a distant 13.7 billion light years away, which is the actual size of the universe. The universe was born from the Big Bang, an explosion of mind-bogglingly intense energy. Although appearing to stand still, it is, even at this very moment, filled with a dynamic continuum of intergalactic collisions and supernova explosions.

Local group of galaxies
Local group of galaxies (local group of galaxies to which the Milky Way belongs) Diameter: 6 million light years A collection of dozens of galaxies is called a local group of galaxies. Members of the local group of galaxies containing the Milky Way include the Andromeda Galaxy M31 which is twice the size of the Milky Way, as well as the Large Magellanic Cloud and Small Magellanic Cloud which are large groups of stars near the Milky Way. The Andromeda Galaxy is 2.3 million, the Large Magellanic Cloud is 160 thousand and the Small Magellanic Cloud is 200 thousand light years approximately away from the Milky Way. They may be 'near' in astronomical terms, but are actually separated by incredible distances.

Diameter of the Milky Way
Diameter of the Milky Way (The Milky Way) Diameter: 100 thousand light years The galaxy to which the Solar System belongs. It contains roughly 200 billion fixed stars. The central thick area is called the bulge, and the surrounding flat area, the disc. A high-temperature cluster of gas called the halo surrounds the Milky Way in a spherical shape. The Solar System is located on the disc about 30 thousand light years away from the center. The Amanogawa ('Heavenly River' in Japanese) where Orihime (Vega) and Hikoboshi (Altair) meet on Tanabata (July 7th), are other stars within the Milky Way, first observed through telescope by the famous Galileo Galilei.

Diffuse nebula
Diffuse nebula (M42 (Orion Nebula)) Diameter: 30 light years A nebula visible to the naked eye below the three aligned stars of the Orion. It is approximately 1500 light years from the Sun and is shaped like a bird with spread wings. The distance from the tip of one wing to the other is about 30 light years. This nebula actually consists of the glowing of interstellar gas, and it is known to contain many newborn stars.

Solar System
Solar System Diameter: 12 billion km The Solar System consists of the central Sun and the nine planets, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. The distance to Pluto, the farthest from the Sun, is about 6 billion km (average). The Solar System was formed about 4.6 billion years ago when interstellar clouds, which were floating in space, were pulled together by gravity and began to rotate, pulling mass into the center to form a primordial solar nebula. The other planets are believed to have formed from the gas and dust which remained in the surrounding area. Although Pluto used to be classified as a planet, it has been classified as the dwarf planet category at the general meeting of International Astronomical Union(IAU) which was held on August 2006.

The Sun
The Sun Diameter: 1.39 million km The Sun, which showers many blessings on the Earth, is large enough for more than 110 Earths to be lined up along its equator. Its mass is the equivalent of 330 thousand Earths. It has a core temperature of approximately 15 million degrees Celsius, and a surface temperature of approximately 6000 degrees Celsius. The black spots, which form in strong magnetic fields, are somewhat cooler at about 3700 degrees Celsius. Plasma, emitted by the Sun, reaches the earth to trigger auroras. In about 5 billion years, the Sun is expected to deplete its hydrogen supply and become a red giant, expand and then finally cool down.

Jupiter
Jupiter Diameter: 142,984 km Jupiter, with its beautiful stripes, is the largest planet in the Solar System and is a typical gaseous planet. Its diameter is about 10 times that of Earth and its volume about 1300 times. Its rotational speed is the fastest among the planets, at 9 hours and 56 minutes per revolution. Near the equator on the southern hemisphere of Jupiter, there is a gigantic atmospheric swirl approximately 38,500 km in length by 13,800 km in width, which is called the Great Red Spot. This giant swirl, which could easily contain three Earths, was first discovered by a British astronomer in the 17th century, and since, has been visible from the earth for the more than 300 years.

Saturn
Saturn Diameter: 125,200 km A giant gaseous planet, like Jupiter, positioned sixth from the Sun. Its most prominent feature, its large surrounding ring, was first discovered by Galileo Galilei. As telescopes of the times were primitive by today's standards, Galileo recorded the ring as "an ear-like object" in his notebook. Saturn's ring consists mainly of ice and rock particles, and it rotates faster towards the inside (planet side) of the ring. In addition, Saturn has many satellites, of which the most famous, Titan, has a diameter of about 5,150 km.

The Earth
The Earth Diameter: 12,756 km The planet on which mankind lives, the only aqueous planet in the Solar System, positioned third from the sun. The atmospheric layer, consisting mainly of nitrogen and oxygen, stores heat from the sun while the ozone layer, approximately 25-40 km above the ground, absorbs hazardous UV rays. There are currently many serious environmental issues such as the rising temperatures due to carbon dioxide emissions (global warming) and the destruction of the ozone layer by chlorofluorocarbons. The orbital period of the Earth is approximately 365.25 days, and its period of rotation is an average 23.93 hours. It experiences seasonal changes owing to the tilt of its rotational axis.

Uranus
Uranus Diameter: 51,118 km The seventh planet of the Solar System, accidentally discovered in 1781 by William Herschel of England. Its most unusual feature is its rotational axis which is tilted 98 degrees from the orbital axis, orbiting around the Sun almost toppled over sideways. It is believed that shortly after Uranus was born, it collided with a giant celestial body causing its rotational axis to tip over. Cloud movements observed by Voyager 2 in 1986 demonstrated that a violent wind in the range of 7900 km per hour blows on Uranus.

Neptune
Neptune Diameter: 49,528 km The eighth planet in the Solar System, discovered through the powers of mathematics. Following the discovery of Uranus in 1781, it was found that its actual observed orbit deviated from the theoretical orbit derived from Newton's law of gravity. Mathematicians John Adams and Urbain Le Verrier hypothesized that this was caused by Uranus' orbit being disrupted by the gravitational pull of an unknown planet. They calculated the location of this new planet. In 1846, Galle at a German observatory, made a search based on their calculations and finally discovered Neptune.

Venus
Venus Diameter: 12,104 km Venus, familiarly referred to as the morning or evening star. Because of its similarity in size to the Earth, Venus has, in the past, been theorized to be Earth's twin planet. However, investigations revealed that Venus, with a surface temperature of about 465 degrees Celsius, has an environment completely unlike that of the Earth. Starting with Venera 1 of the former Soviet Union in 1961, a great number of probe spacecraft have been launched, only to be destroyed by the high temperatures and pressure in the range of 90 times that of Earth. Venera 7 became the first to successfully land in 1970.

The Moon
The Moon Diameter: 3,476 km The Moon is Earth's only satellite and the celestial body closest to the Earth. It is about one fourth the size of the Earth. The difference between these two sizes is often likened to the difference in size between a table tennis ball (40 mm) and a pinball (11 mm). There are countless craters on the Moon's surface, said to number over 300 thousand just on the side facing the Earth. Soil (and rock) samples were brought back to Earth in the voyage to the moon made in 1969 by Captain Armstrong and his crew of the Apollo 11, who took the first step on the moon in the history of mankind. Surveillance studies of the moon continue to this day.

Mars
Mars Diameter: 6,794 km In Europe, Mars was named after Mars, the god of war, from the auburn glow of its surface which is suggestive of blood. It is about half the size of the Earth. In 1894, an American businessman named Percival Lowell announced that the striations seen on the surface of Mars consisted of waterways built by a sophisticated civilization. However, this 'Martian' theory was later disclaimed by research. Mars features diverse geological formations, including a volcano 25,000m in height and a giant canyon 4000km long.

Mercury
Mercury Diameter: 4,880 km Mercury, the second smallest planet in the Solar System next to Pluto with a diameter of approximately 4880 km (about two fifths that of the Earth). Its orbital period is short at 88 days while in contrast, its rotational period is long at 59 days. Therefore, a single solar day lasts for 176 days, with daytime temperatures as high as 427 degrees Celsius, dropping to -183 degrees Celsius at night. Although Mercury used to be shrouded in mystery, the American Mariner 10, launched in 1973 revealed facts such as the existence of giant craters 1300km in diameter.

Pluto
Pluto Diameter: 2,274 km The outermost planet known in the Solar System to date. No planet-probing spacecraft has ever reached its vicinity, leaving much of it a mystery. The inclination of Pluto's orbit to the ecliptic is large at 17 degrees, and its eccentricity is the largest of the planets. Its average distance from the Sun is approximately 5.9 billion km, and it takes 248 years to make a full orbit of the Sun. The Pluto space probe New Horizons, which NASA is planning to launch, is scheduled to land on its surface in about 10 years. Although Pluto used to be classified as a planet, it has been classified as the dwarf planet category at the general meeting of International Astronomical Union(IAU) which was held on August 2006.

Mount Everest
Mount Everest Elevation: 8.848 km The highest mountain in the world, towering on the border between Nepal and the Tibet Autonomous Region of China. The Tibetan name "Chomolungma" means "Goddess of the Earth" or "Mother Goddess of the World." The English name "Everest" comes from the British surveyor George Everest, known for his precise trigonometric survey of the Indian subcontinent.The height was revised to the present value of 8,848 m in 1954.The height has been repeatedly revised since then. China's State Bureau of Surveying and Mapping annouced in 2005 that the height of Everest is 8844.43 m (error range 0.21 m), which is 3.7 m lower than the previous official height of the mountain.

Mount Fuji
Mount Fuji Elevation: 3.776 m Located in Japan Border between prefectures of Shizuoka and Yamanashi Not only is it the highest mountain in Japan, but it has been worshiped as a spiritual peak since ancient times owing to its beauty. The name Fuji is said to come from the Ainu word "Fuchi" meaning fire. It was formed through eruption. Roughly 11 thousand years ago, an explosion occurred on the west side of the peak of Old Fuji, and the Mount Fuji we know today (New Fuji) was formed from the multitudes of lava which gushed out at the time. Later, the Old Fuji and New Fuji were stood side-by-side, but an avalanche caused by weathering destroyed the Old Fuji, leaving the New Fuji to remain standing as we see it today.

Angel Falls
Angel Falls Drop: 979 m Located in Venezuela Central Bolivar State A waterfall boasting the largest height for any single-drop fall in the world. It is located approximately 250 km south-southeast of the state capital, Ciudad Bolivar on the Zurn River, a tributary of the Caroni River, and drops almost vertically from the Auyan-Tepui table mountains located in the central Guiana Highlands. Due to the length of the drop, the falling water turns to mist in midair, thus it is also known as a waterfall with no basin. The waterfall is named after the American explorer James Angel who discovered it in 1935.

CN Tower
CN Tower Height: 553.33 m Located in Canada Toronto A rocket tower. This landmark is visible from anywhere in the city. Originally, it was built as a radio tower for television and radio and was named the CN Tower from the initials of the Canadian National Railway. The tower has a glass floor offering a view that is as superb as it is thrilling. It is a standard stop on any Toronto sightsee and is always bustling with foreign tourists.

Empire State Building
Empire State Building Height: 381 m Located in U.S.A. New York State Manhattan A skyscraper located on Fifth Avenue in Manhattan, designed by the architectural firm of Shreve, Lamb  Harmon in response to a request by Pierre, a fourth-generation Dupont. Plans were drawn up during the robust economy of the 1920's, but construction work was not actually initiated until 1930 following the Great Depression. Although it may seem hard to believe, when it was first built, it was short of tenants and virtually empty for some time. At 102 floors and 381m high, it reigned as the highest building in the world until it lost its position to Sears Tower.

Ayers Rock
Ayers Rock Height: 348 m Located in Central Australia Approximately 340 km southwest of Alice Springs The world's largest monolith. It has a perimeter of about 9000m and reaches to a height of approximately 867m above sea level (about 348m above the ground). From its majestic appearance in the middle of the desolate desert, it is referred to as 'the bellybutton of the earth.' The site was sacred for the aborigines, who called this giant rock as "Uluru." These are numerous mural paintings depicting legends of the Anangu tribe on the rock's wall. The rock changes color from orange to red to purple as the sun moves across the sky.

Cologne Cathedral
Cologne Cathedral Height: 157 m Located in Germany Cologne Its official name is Dom St. Peter und Maria. The cathedral is the largest German gothic architecture in the world. Its construction started in 1248 after being commissioned by the archbishop, but required centuries for its completion. A portion of the interior was completed in 1320, but the stained glass windows took from the beginning of the 14th century to the 16th century, while construction of the transept spanned from 1322 to the end of the 15th century. Construction work was suspended once in 1560, but was resumed in 1842 upon the orders of the king of Bayern and was completed in 1880 after more than 600 years. Its twin towers are 157 m high and approximately 61 m wide. In 1996, it was designated a World Heritage.

Pyramid
Pyramid (The Great Pyramid of King Khufu) Height: 147 m Located in Egypt Giza Giant quadrangular pyramid constructions built around 3000 B.C. in ancient Egypt. There are various theories regarding the purpose of their construction, including those that claim they were tombs of kings, or public works projects during the agricultural off season. The world's largest pyramid is the primary pyramid of King Khufu standing on the Giza Plateau. It is 147 m high, with each side of the base being 230m long. Roughly 2.3 million stones weighing about 2.5 tons each were used in its construction. One of the many remaining mysteries of the pyramid is the precision of its dimensions. The discrepancy between the four bases of the pyramid is only 50 cm, which corresponds to just 0.2 mm error per meter, suggesting the existence of sophisticated engineering and measurement technology.

Ferris wheel
Ferris wheel (BA London Eye) Height: 135 m Located in England London South shore of the Thames River The "London Eye," a large ferris wheel stands on the south shore of the Thames River across from the Old County Hall at a height of 135 meters and weighing 1900 tons. It was built as part of Britain's millennium project. A giant 25-person capsule takes you on a pleasant aerial voyage, traveling full circle in about 30 minutes. In midair, you have a panoramic view of such London landmarks as Big Ben, Buckingham Palace and Saint Paul's Cathedral. On a sunny day, this view may reach as far as 40 kilometers. In March 2008, the record for the world's largest Ferris wheel was broken by the "Singapore Flyer" in Singapore, standing at a height of 165 meters.

Statue of Liberty
Statue of Liberty Height: 93 m Located in U.S.A. New York State Liberty Island The symbol of freedom which dominates Liberty Island, New York. Created by the French sculptor Bartholdi, it was presented to the U.S.A. by France in 1886 to celebrate the 100th anniversary of the independence of the United States. The Statue is approximately 46m high standing on a pedestal of 47m, and weighs roughly 250 tons. She carries a torch in the right hand and the Declaration of Independence in the left. With her left foot, she steps on the chains of tyranny. The seven spikes in her crown represent the seas and continents of the world, spreading the message of freedom throughout the world. In 1984, the Statue was declared a World Heritage.

Sequoia tree
Sequoia tree (The General Sherman Tree) Height: 83 m Located in U.S.A. State of California Sequoia National Park The world's largest tree. There are two types on the west coast of North America, and they are extremely longevous living for over 3000 years. The largest tree in the world is named General Sherman and is growing wild in the Sequoia National Park at approximately 83m high with a diameter of 11 m, and is estimated to be 2100 years old. The volume of the trunk was 1487 cubic meters in 1980, and is said to have reached 1500 cubic meters as of 2004.

Jumbo jet airplane
Jumbo jet airplane (Jumbo jet (Boeing 747)) Length: 70 m Flying from city to city worldwide, the jet-engine plane has changed our concepts of distance and time with its high speed and transportation capacity. In the 1970's, aircraft of a larger scale were developed in response to the sudden increase in demand for the air transportation of passengers and cargo together with the overcrowding of airports. The Boeing 747 was one such plane and, with repeated upgrades since its first flight in 1969, it still crisscrosses the skies today. It has a body length of 70.6m, a wingspan of 59.6m, a tailplane tip 19 meters above the ground and is familiarly referred to as the "Jumbo" from its size, load capacity and power.

Triumphal arch
Triumphal arch (Arc de Triomphe de l'Etoile) Height: 50 m Located in France Paris Place Charles D'Gaulle The world's largest triumphal arch which stands in the Place Charles De Gaulle in Paris, France. Its construction was started in 1806 as a monument to Napoleon's conquests, and was completed in 1836. It boasts a height of 50 m and width of 45m, and is adorned with various relief sculptures, such as "The Departure of the Volunteers of 1792," a masterpiece by sculptor Rude, as well as works by romanticist sculptors. Inside, there is a resting place for an unknown soldier and even now, at 6:30 every evening, a memorial flame is lit. Centering on the Arc de Triomphe de l'Etoile, twelve main streets, including the Champs Elysees radiate out in all directions and from the top, a panoramic view of the modern city of Paris can be seen.

Whale
Whale (Blue whale) Length: 33.6 m Order Cetacea Family Balaenopteridae Blue whale (Balaenoptera musculus) A large ocean mammal. Presently, about 82 species have been identified. Of these, the Blue Whale is the largest in the world. Measurements as large as approximately 33.6m full length and weight of around 190 tons have been recorded. Owing to their overexploitation, their number has decreased dramatically to 6,000 - 14,000. Whaling has been banned internationally since 1966. Melville, the author of the literary work "Moby-Dick: or, the White Whale" likened the greatness and power of the whale to the destructive power of the universe. Research into the mechanisms of the high intelligence and communication abilities possessed by many whales is currently in progress.

Sphinx
Sphinx (Sphinx of Giza) Height: 23 m Located in Egypt Giza An imaginary beast with the body of a lion and the head of a man. It was regarded as the symbol of "the mysteries of life, ignorance, and evil" in medieval Europe, as it had proposed a riddle to Oedipus in Greek myth. It dates back to the earliest era of Egyptian civilization. The Sphinx, which sits in front of the pyramids of Giza, at 57m in length and 23m in height, is the world's largest and oldest statue. The lion symbolizes Pharaoh (the king) while the king's headdress (Nemes) on the human head symbolizes power. It is believed to have been modeled after King Khafre himself, who ruled in the Fourth Dynasty around the year 2600 before Christ.

Tyrannosaurus
Tyrannosaurus Length: 15 m

The largest carnivorous dinosaur populating North America in the later stage of the Mesozoic era of the Cretaceous period, 67 million years ago. It had a giant body of approximately 15m in length, 6m in height and 7 tons in weight. It is believed to have walked on its two hind legs, balancing with its giant 1.5 m long head and its long tail. Footprints found in geologic stratum surfaces were measured to be approximately 67 cm long and 76 cm wide, with a stride of about 4 m. Still-soft blood vessels and bone cells with cell nuclei intact were discovered from a thighbone fossil in March, 2005.

Double deck bus
Double deck bus (Doubledecker) Height: 4.4 m

Although double decker buses can be seen in various countries worldwide, the most well known is the Double Decker of London. It was successfully put into service for the first time in London in 1910. The following year, the route carriages that had been the main means of transportation were forced to be abolished. In the following year, horse traffic, hitherto main public transpotation of London, was replaced by the buses, and disappeared from London. The 4.4 m high, bowler-hat-shaped roly-poly Routemaster, in particular, with its charming bright red body, became a symbol of London. The Routemasters have long been one of the most popular public transpotation among both locals and tourists. The Routemasters have been replaced by the new Bendy buses in 2005, however, they have not completely disappeared, as they still run in the heritage routes today.

Ostrich
Ostrich Height: 2.5 m Order Struthioniformes Family Struthionidae Ostrich (Struthio camelus) The largest species of all present-day living birds. It inhabits Africa. Although it has wings it cannot fly, but runs at 60 km per hour or faster upon sensing danger. The male is about 2.5m in head height and weighs about 150 kg. It also lays the largest egg of all birds. A large egg may measure 15 cm in diameter and weigh 1600 g. The ostrich is polygamous with 3-5 females each laying 4-8 eggs in the nest made by the one male. These many eggs are kept and protected by one male alone at night, and by several females in turns by day.

Giraffe
Giraffe (Masai giraffe) Height: 5.8 m Order Artiodactyla Family Giraffidae Masai giraffe (Giraffa camelopardalis tippelskirchi) The tallest of the land mammals. There is an anecdote saying that during Creation, the gods were hard pressed for ideas and so gathered the left-over odd body parts which they put together to make the giraffe. Its peculiar shape, with its long neck and short torso, front legs that are longer than the hind legs, are testimony to the efforts of evolution in trying to adapt itself to its natural environment. The largest giraffe on record was a male Masai giraffe named George, brought to England from Kenya in 1959, who stood 5.88 m tall.

Elephant
Elephant (African elephant) Height: 3 m Order Proboscidea Family Elephantidae African Elephant (Loxodonta africana) The largest land animal in the world. It has an elongated upper lip, a dexterous trunk and large ears, and leisurely roams the forests and Savannah of Africa, India and Southeast Asia. It is highly intelligent and docile despite its mighty form, thus has been close to man religiously and culturally, in various regions of the world for over 1000 years. However, due to overexploitation for their ivory tusks, the numbers of elephants are decreasing. Of large African elephants, there is one on record for weighing roughly 10 tons, with shoulder height at about 4 m (about 3 m is the average), in Angola in 1955.

Sunflower
Sunflower Height: 2 m Order Asterales Family Asteraceae Common sunflower (Helianthus annuus) An annual plant native to North America, comprising approximately 160 varieties. It flowers from July to September high above the ground, proudly announcing the summer season. The tallest on record was found in the Netherlands in 1986, at 7.76m (the average is about 2m). The flower at the far end of the straight, upward-reaching stem is also large. The largest one on record was grown in Canada in 1983, with a diameter of 82 cm. It is often referred to as the "flower of the sun" from its sunny shape and the fact that it turns to face the sun.

Turtle
Turtle (Loggerhead turtle) Length: 1.2 m Order Testudines Family Cheloniidae Loggerhead sea turtle (Caretta caretta) A reptile with a hard shell. Roughly 220 species populate the earth, on land, in ocean, or both. Of these, the loggerhead turtle, a large sea turtle, may exceed 1.2m in shell length and 200kg in weight. Its habitat ranges from temperate to subtropical oceans and it lays eggs at the highest latitude of all sea turtles. It lands on sandy beach to spawn and a single female can lay about 120 eggs. As coastal region developments progress worldwide, many turtles are losing their spawning grounds and their numbers are decreasing.

Human
Human Height: 1.7 m Order Primates Family Hominidae Human (Homo sapiens) The human, who continues evolution as homo sapiens. This 'intellectual life form' uses tools and fire, speaks languages, builds civilizations, probes space with sophisticated technology, and works to unfathom the wonders of the microscopic world. Although height and physique vary by racial group, age group and by individual, our body height and weight fluctuate over the day. In the afternoon, our height decreases by 1-2 cm, while our weight increases by 2 kg, on average. The human body, with its meticulously precise mechanisms where a myriad of muscles, nerves, cells and the movement of mind correlate together, holds infinite potential.

Chimpanzee
Chimpanzee Height: 77-92 cm Order Primates Family Hominidae Chimpanzee (Pan troglodytes) The animal closest to the human. Some are even human-like in their gestures and expressions. It is believed that the chimpanzee shares a common ancestor with man, but branched off about 5 million years ago. It inhabits regions of western to central Africa. Chimpanzees display a characteristic use of tools, using branches to eat ants, or rocks to crack fruit open. By learning, they are capable of communicating with humans using sign language and graphic characters, and also show social behavior.

Dog
Dog (Golden Retriever) Height: 51-61 cm Order Carnivora Family Canidae Golden Retriever: domestic dog (Canis familiaris) The dog has been living with man since ancient times. This light golden-haired, soft-featured dog, in particular, is mild-mannered and has a strong sense of duty, thus is popular as a domestic dog. It is said to have originated in the latter half of 20th century England, a result of crossbreeding between the Flat-Coated Retriever and Tweed Water Spaniel. Golden Retrievers make superior hunting dogs, and are active in service and competitions.

Rabbit
Rabbit (Hare) Length: 40-55 cm Order Lagomorphia Family Leporidae Japanese hare (Lepus brachyurus) It senses danger with its long, freely moving ears, and is an excellent jumper and extremely agile. In northern Europe, it became a symbol of Easter, a celebration of spring, as its high fertility represents "spring" and "rebirth." There are two main types: the hare and the coney. Conies are kept as pets, while hares are mostly wild, nesting in hollows in the ground and bushes. A newborn baby rabbit is already fully furred, with eyes open, and is able to walk immediately.

Apple
Size: 8.5 cm Apple (Fuji) Order Rosales Family Rosaceae Variety Fuji: common apple (Malus domestica) A deciduous tree of the family Rosaceae, native to the area from western Asia to southeastern Europe. The fruit is close to the heart of man, as the forbidden fruit eaten by Adam and Eve, and the fruit that triggered the British physicist Newton to discover the law of gravity. Most of the roughly 15,000 species in existence are grown in temperate zones worldwide. The variety called Fuji, popular in Japan, is approximately 8.5 cm in size. An apple harvested in England in 1997 weighed as much as 1.68 kg.

Soccer ball
Soccer ball (Size 5 ball) Diameter: 22 cm Size 5 is the official ball size Soccer, the British-born sport that is now taking the world by storm. The name "soccer" comes from "assoccer," the shortened version of its official name of "association football." Only several countries, including Japan, still use this name to refer to the sport. The standard ball, which becomes the center of the feverish excitement and glory, is a sphere made up of twelve pentagons and twenty hexagons. It is extremely stable and sturdy, and in addition exhibits mid-air curving exactly in accordance with the laws of fluid dynamics. Variously designed balls developed to a construction of higher precision are currently being used. The size 5 ball is the official size, to be used in the 2006 World Cup in Germany.

CD
CD Diameter: 12 cm

A recording medium of optical disc specification. CD stands for Compact Disc. The CD is vital to such activities as enjoying recorded music and installing PC software. It is a polycarbonate disc with an outer diameter of 12 or 8 cm and thickness of 1.2 mm. It first appeared in Japan and Europe in 1982. There are several types, including the CD-ROM (Read Only Memory) for reading data only, the CD-R (Recordable) for once-only recording, and the CD-RW (ReWritable) for multiple recording/deleting. All of these discs apply the same mechanism, of etching data with the concavity and convexity patterns and reading them with use of laser beam.

Mouse
Mouse (House mouse) Length: 6.5 cm Order Rodentia Family Muridae House mouse (Mus musculus) An rodent mammal frequently seen all over the world with its unique feature of prodigious reproductive ability and incisor tooth that keeps growing in the course of its life cycle. Among them, the group of Mus musculus including house mouse, in particular, has a deep involvement with human beings and historically been treated as typical vermin as it was feared as a messenger of the devil. Nowadays however, as lab animal it has been contributing to us in the development of such fields as medical technologies.

Katydid
Katydid (Katydid) Length: 38-57 mm Order Orthoptera Family Tettigoniidae Katydid (Gampsocleis buergeri) An insect familiar to us as in "The Ant and the Grasshopper" (Aesop's Fables). In Japan, from early summer to fall, it can be heard singing in the grass, spreading a seasonal spirit. In England, it sounds as singing "Kate she did (Kate has come)" thus is familiarly referred to as a "Katydid." Females have ovipositors the size of their abdomens, which they insert into the soil to lay their eggs at the end of summer. The eggs overwinter in the ground and hatch around June of the following year.

Cockroach
Cockroach (Smokybrown cockroach) Length: 30-35 mm Order Blattaria Family Blattidae Smokybrown cockroach (Periplaneta fuliginosa) Roughly 4000 species populate the entire world, mainly in tropical areas. Some are as large as 10 cm, but most domestic types are 1 - 4 cm. The common species found in Japan is known as the smoky brown cockroach and is 30-35 mm in average length, characterized by a shiny black-brown body. It moves rapidly, at about 1 m per second, and utilizes its caudal appendage, an organ which detects airflow and vibrations, to make extremely fast escapes. It multiplies by laying eggs from spring to fall, in an ootheca which contains 41 or so eggs.

Bee
Bee (Honey bee) Length: 1.3 cm Order Hymenoptera Family Apidae Honey bee (Apis mellifera) There are over 120 thousand diverse species of bee worldwide. Of these, the honey bee exhibits unique behavior. In the bee's nest, one queen, about two thousand males, and several thousand worker bees operate a highly sophisticated and systematic social life. The life of a worker bee is short at about 40 days, but the queen lives for 3-5 years, and continues to lay 1000-1500 eggs every day. In the female-dominated honey bee society, male bees exist solely for the purpose of mating with the queen.

Golf ball
Golf ball Diameter: 4.267 cm

Golf is believed to have originated in Ireland, when a pasture worker playfully hit a rock aimed for a jack rabbit hole while grazing. By the 17th century, feather balls made of cowhide and stuffed with feathers, appeared. Later, balls using the gutta-percha, a type of rubber tree, and thread-wound balls paved the way for the present-day golf ball. The size of a golf ball is established by the regulations as being 4.267 cm or larger in diameter, and weighing 45.93 g or less.

Coin
Coin (Penny) Diameter: 1.9 cm

During the period of colonization by England, Americans' minting of their own coins was restricted. As a reaction to this situation, the U.S. monetary system was established rapidly upon gaining independence. The basic monetary unit employed was a decimal system proposed by Thomas Jefferson. The front of the penny depicts an image of Abraham Lincoln, the sixteenth American President, or the "Father of Emancipation," while on the flip side the Lincoln Memorial is inscribed. It is made of 97.5% zinc and 2.5% copper.

Film
Film (35mm film) Diameter: 35 mm

A general name for thin membranes. In a narrow sense it refers to the image-recording media used to record photographs and movies. Photographic film was invented around 1840. It is a thin membrane coated with photosensitive material (mainly silver compounds, specifically silver salts). The invention of this easily handled, mass-producible film to replace the conventional glass photographic dry plate was undoubtedly the driving force behind the popularization of photography. Film that shows the subject in inverse color is called a negative, and one that shows the object image as it is, is a positive film. Presently, the 35 mm film, referred to as the"135" by specification, is the most popular worldwide. 35 mm refers to the width of the film, while the actual range in which the image is recorded measures 24~36 mm. It was developed based on the film used for shooting movies.

Fly
Fly (Housefly) Length: 9-11 mm Order Diptera Family Muscidae Housefly (Musca domestica) Diverse species of flies populate the world, ranging in size from 8-15 mm for the larger and 2-3 mm for the smaller. Their larvae frequently occur in animal feces and decayed organic material. In particular, the house fly, which inhabits human domestic areas, is about 9-11 mm in average length and is deemed a sanitary pest. The period required for newborn larvae to reach maturity and spawn is short, at twenty days, thus generation changes occur at the phenomenal rate of ten or more cycles per year. The housefly has compound eyes like the butterfly, dragonfly and honey bee, and thus sees a mosaic of the objects in its view.

Ladybird
Ladybird (Seven-spotted ladybird) Length: 7-8 mm Order Coleoptera Family Coccinellidae Seven-spotted ladybird (Coccinella septempunctata) The adult is a semispherical small beetle. Most are several millimeters to a centimeter in size, and vary widely in color and number of dots. The English name "ladybird" is traced to the Virgin Mary, and the insect is regarded world over as a symbol of happiness. Many species that eat crop leaves are despised as pests, while others, like the seven-spotted ladybird that consumes aphids and controls plant diseases is considered a beneficial insect. In recent years, the seven-spotted ladybird has been increasingly utilized as a means of pest control taking advantage of its feeding habit, by artificially letting them loose in fields.

Ant
Ant (Black mountain ant) Length: 4-6 mm Order Hymenoptera Family Formicidae Black mountain ant (Formica Japonica) As ants live in communities of large numbers, they are referred to as 'social insects.' They form sophisticated and hierarchic societies, and inhabit a wide range of areas from tropical areas to cool temperate zones by adapting to the environments. They are strong, able to use their large jaws to carry objects many times their own size. The black mountain ants which we commonly see in Japan are worker ants, having a body length of 4-6 mm, while the queen ant is 1 cm or larger (the figure shows a worker ant). As many as 16 thousand or more work ants may live in a single burrow which is usually 2-4 meters deep.

Mosquito
Mosquito (House mosquito) Length: 5.5 mm Order Diptera Family Culicidae House mosquito (Culex pipiens) There are a total of roughly 2500 species. They are sanitary pests who pass on pathogenic agents by sucking blood from humans and others using their long probosces. However, only the females suck blood in order to take in high-quality protein to spawn. The house mosquito is said to suck blood in an amount equal to its own body weight, and is active mainly from dusk to dawn. It relishes birds in addition to humans. The West Nile Fever which broke out in New York in 1999 was transmitted mainly by the house mosquito and the effects of the virus are believed to have been amplified by such birds as crows.

Flea
Flea (Cat flea) Length: 1-9 mm Order Siphonaptera Family Pulicidae Cat flea (Ctenocephalides felis) Fleas are parasites that live off warm-blooded animals by sucking blood from their hosts. Many species are transmitters of infectious agents. In medieval Europe, the rat flea which carried the plague bacillus caused the Black Death plague. The flea has a unique mechanism for sucking blood whereby it pierces the host with the lacinia in its mandibles and activates two pumps: one to suck blood and another to send in saliva to prevent the blood from clotting. The flea is also a good jumper, capable of reaching heights up to 150 times or more of its own height in a single jump using a protein called resilin in its hind legs.

Water flea
Water flea (Water flea (Daphnia galeata)) Length: 2 mm Order Cladocera Family Daphnidae Water flea (Daphnia galeata) A zooplankton belonging to the crustacean class along with prawns and crabs. The Daphnia galeata species has a characteristic pointed casque-like head. The species that populates ponds where they have few natural enemies such as fish, have round heads. It is believed that this pointed headpiece evolved as a means of self protection. The water flea has eyes, a heart and reproductive organs, all built into its tiny body. It swims by beating against the water using a second antenna called the swimmeret.

Rain
Rain (Raindrop) Diameter: approx. 0.5 mm

The phenomenon in which water vapor in the atmosphere gathers to form a water drop, reaching a certain size where it can no longer keep floating in the air and thus falls to the ground. When the water drop is 0.5 mm or larger in diameter, it is called rain, and anything smaller is called drizzle. The speed with which rain falls is about 2 m per second for an average-sized raindrop, and about 9 m per second for large drops. Raindrops become rather bun-shaped, as they are subject to air resistance as they fall. When the upper-level air is cold, the vapor becomes frazil and if it falls to the ground without melting, we observe it as "snow."

Sesame seed
Sesame seed (White sesame seed) Diameter: 1 mm Order Scrophulariales Family Pedaliaceae White sesame seeds (Sesamum indicum) An annual plant. The stem having a square cross-section grows to about 1 m in height. The sesame that we commonly consume as food is the seed that has fallen from the matured shell. The thickness of a grain is about 1mm, with a length of 3mm and a width of 1.5mm. This small seed has a high protein, carbohydrate, fat and vitamin E content. White sesame, in particular, has a high fat content at 50-55 percent, and is thus used for its oil.

Snow crystal
Snow crystal Diameter: 1 mm

An art object produced by nature, whereby no two are ever identical in shape. They come in various forms, from thin hexagons, to six branches stretching out in a star-like or tree-like fashion, or hexagonal cylinders. They are normally 0.1-5 mm in size, but in rare cases can exceed 10 mm. Crystals of size 0.1 mm or smaller are called frazil, and are the seeds of snow crystals. As the shape of a snow crystal reveals the path in which it has grown and fallen, we can know of the weather conditions (temperature and humidity) of the upper-level air by observing the snow crystal itself. The German astronomer Johannes Keppler noted the fact that snow crystals are hexagonal in shape, and was the first to explain why they are so.

Paramecium
Paramecium (Paramecium) Length: 0.25 mm Order Peniculida Genus Paramecium Paramecium (Paramecium caudatum) A type of single-celled animal organism that consists entirely of one cell. It occurs in rivers, rice paddies and ponds, traveling by moving the fine cilia which cover its body. It consumes mainly bacteria using the horn-shaped mouth in its center, and excretes waste and excess water through its cytopyge. Although it is capable of dividing to multiply by itself, it possesses a genetically fixed duration of life (limited number of divisions), thus, repeated division would only lead to its extinction. However, this organism has the unique ecology of being capable of rejuvenating by sexual reproduction with another independent cell.

Closterium
Closterium Length: 0.1 mm Order Zygnematales Genus Closterium Closterium A green algae with a characteristic gently curving crescent shape. It is a typical genus of the group of single-celled plant organisms called desmids, and consists of approximately 80 known species. The fine feathery substance seen on the surface of the dirt at the bottom of wetlands, lakes, and swamps is actually this closterium. Although it has no stem or leaves, it possesses chloroplasts inside its body and lives by photosynthesis, thus, is a bona fide plant.

Ameba
Ameba (Ameba proteus) Length: 0.6 mm

A type of single-celled animal organism that consists entirely of one cell, found in the dirt and soil at the bottom of lakes and swamps. It is amorphous, and travels by stretching its body in a gelatinous fashion, into a shape that is referred to as a pseudopod. The pseudopod is also used to intake bacteria, other protozoans and algae. At the beginning of cell division of an amoeba, numerous protrusions form around its body and the cell eventually becomes pinched, then divides into two. The typical species of Amoeba proteus divides in roughly 30 minutes. "Amoeba" is Greek for "change."

Ovum
Ovum (Human ovum) Length: 0.2 mm

The ovum is the largest cell within the human body. It is about 200 micrometer in diameter and is visible to the naked eye. The cells (called oocytes) which are the basis of ovums are already present in the ovaries of a newborn baby girl. No new oocytes are ever produced after birth. At 16-20 weeks of pregnancy, there are already 6-7 million oocytes in the ovaries of the female embryo, the majority of which gradually disappear. In other words, ovums may be called the longest-living cells in the human body.

Tick/ mite
Tick/ mite (House dust mite) Length: 0.5-1 mm Order Acarina Family Dermanyssidae House dust mite (Ornithonyssus bacoti) The general name for the mite and tick order. They feed parasitically on plants and animals. The body has a degenerate structure (capitula, prosoma and metasoma), and there is no distinction between the head, chest, or abdomen. The larva has only 3 pairs of legs (6 legs), but the adult tick has 4 pairs (8 legs). It inhabits the world over. The size of the house dust mite, which causes considerable itching in its victim when it bites and sucks blood, is only 0.5-1 mm, a size barely perceivable by the naked eye.

Sperm
Sperm (Human sperm cell) Length: 60 ƒÊm

It is shaped like a tadpole, with the nucleus dominating the majority of the head. Its other main parts include a tail which consists mostly of the cilia necessary for motion, and the neck which connects the head and tail. The head of a human sperm cell is shaped like an elliptical pear, with a major axis of about 4-5 micrometer, and minor axis of about 2.5-3.5 micrometer. In humans, 1-6 cc of semen, containing 60-100 million sperm cells per cc, is discharged per ejaculation.

Pollen
Pollen (Japanese cedar pollen) Diameter: 30 ƒÊm

The male sex cell, corresponding to sperm cells in animals. The male sex cells of the Japanese cedar pollen range in shape from circular, elliptical to triangular, and are diverse in color as well. The male sex cells of the maidenhair tree (gingko) actually move like human sperm cells. The pollen of the Japanese cedar, Japanese cypress, and Gramineae plants are well known as seasonal allergens. Pollen allergy is sometimes referred to as hay fever in Europe and the United States, a relic from the time before this illness was found attributable to pollen.

White blood cell
White blood cell Diameter: 12-20 ƒÊm

A cellular component of blood. White blood cells protect the body from infection, by ingesting the microbes that enter the body or by producing antibodies. They are normally distributed throughout the body, but when a single white blood cell finds an infected or trouble site, it calls over scores of others. These colorless, nucleated cells are categorized into three types: granulocytes, monocytes, and lymphocytes. They are larger than red blood cells but far fewer in number. They are named white blood cells from the fact that when collected in masses they appear white.

Chromosome
Chromosome Diameter: 10 ƒÊm

Carriers, of genetic material consisting of DNA and protein, which communicate information (genetic) that passes on the characteristics of the parents (previous generation). Chromosomes differ in number and shape by species. Twenty-three pairs (46 single) of chromosomes are contained in the nucleus of a human body cell. Numbers 1 through 22 are called autosomes while the 23rd is called the sex chromosome as it determines gender. An X and X combination of this sex chromosome produces a female, and an X and a Y combination, a male. The English name originates from the Greek word that means "a colored object."

Mitochondria
Mitochondria Length: 0.5-1.0 ƒÊm

A cell organelle present within the cytoplasm of all organisms, with the exception of bacteria and blue-green algae. It has its own DNA and self-replicates. It is responsible for respiration and energy production, and is sometimes referred to as the 'respirator of the cell.' It is cylindrical or spherical in shape. Mitochondria are present in both the ovum and sperm cell, but only those from the ovum are passed on to the fertilized ovum. It is owing to this trait of mitochondria that we are able to track the ancestry of organisms.

Micro-electromechanical device
Micro-electromechanical device (MEMSi, Micro-Electro Mechanical Systems) Diameter: approx. 10-<100 ƒÊm

Micro-scale devices (about 1 micrometer - 1 mm) such as structures, sensors and actuators, produced using semiconductor manufacturing technology. Nikon has developed its own technology for MEMS device manufacturing by laminating film in multiple layers, and has applied the technology to the development of such devices as IR sensors and optical switches. Using this method, a different function can be attributed to each layer, allowing the production of a high-performance, high-density MEMS with (relative) ease.

Micro-precision optical device
Micro-precision optical device (MLAi, Micro (Multi) Lens Array) Diameter: 10-100 ƒÊm

An optical part consisting of a small optical device with small lenses, with a diameter of between several dozen to hundred micrometers, arranged on its surface. It is used for feeding light into, or retrieving light from, extra-fine optical fibers. For example, the CCD and CMOS used in digital cameras and such are producing finer images as their resolution improves. However, given a CCD or other device of the same size, increasing the number of pixels decreases the size of each element and thus reduces the amount of received light, leading to noise in the recorded image. MLAs which collect light efficiently are used to resolve this problem.

Red blood cell
Red blood cell Diameter: 7-8 ƒÊm

Red blood cells are a component of blood. The name comes from the fact that they appear a red color when in masses, as they contain the oxygen-carrying protein, hemoglobin (blood pigment). The reason blood appears red is that the red blood cells are literally red. They carry oxygen required for energy production from the lungs to other parts of the body, and in turn bring the toxic carbon dioxide back to the lungs. A normal red blood cell is a flat disc shape with a thin center. Red blood cells constitute 40-50% of total blood volume.

Lymphocyte
Lymphocyte Diameter: 8-12 ƒÊm

Spherical cells, classified into either large or small lymphocytes. The lymphocyte content of peripheral blood leukocytes is about 30%, while almost all of the lymph fluid flowing through the body consists of lymphocytes. The lymph gland which becomes swollen when we have a cold is the passage for lymph fluid. Lymphocytes have a memory of any foreign bodies that previously entered the body, and react immediately and aggressively against specific foreign bodies in order to protect the body. It is owing to this immune system mechanism that we do not contract chickenpox or the measles twice.

Yeast
Yeast (Wine yeast) Diameter: 5 ƒÊm

The majority of yeasts decompose sugars and carry out alcoholic fermentation. Since long ago, this property has been utilized to produce alcoholic beverages. Among them, wine yeasts produce wine out of grape juice. The characteristics of the yeast best suited to wine-making enable the creation of a unique, rich flavor. No good wine can ever be made using a wine yeast of bad character, no matter how good the grapes or how careful the processes are.

Colibacillus
Colibacillus Diameter: 2-4 ƒÊm

A bacteria which is invariably present in the large intestines of any healthy person and many warm-blooded animals. It is approximately 0.4-0.7 micrometer wide and 2-4 micrometer long. There are many types of colibacillus, most of which are harmless as long as they stay within the intestines, but which may cause infection in other organ outside of the intestines. There are also highly toxic, pathogenic bacteria which cause diarrhea and enteritis by merely entering the intestines.

Single-electron transistor
Single-electron transistor Diameter: 1.5 ƒÊm

Approximately 100 thousand conventional transistors are required for on/off control of electric current, whereas a single-electron transistor (SET) can do it alone. In 1999, NTT (Nippon Telegraph and Telephone Corporation) became the first in the world to succeed in sample-producing a basic computer circuit by integrating single-electron transistors. Two transistors were created side by side in extreme proximity to realize an ultra-compact inverter circuit, of about 0.1 x 0.2 micrometer core size, and a square of side approximately 1.5 micrometer including electrical connections.

Lactic acid bacteria
Lactic acid bacteria (The figure shows lactobacillus?) Diameter: 2-9 ƒÊm

The general name used to refer to the bacteria that produce lactic acid when decomposing sugar during fermenting, such as lactobacillus and bifidobacteria. As this lactic acid is believed to aid digestion and prevent infection in the intestinal tract, as well as improve the balance of intestinal bacterial flora, these bacteria are known as 'good bacteria.' Lactobacillus can survive in every nook and cranny of nature; they exist in the mouth and gastrointestinals of humans. Many types of lactobacillus, including lactobacillus bulgaricus, are used in fermented foods such as cheese and yoghurt, as well as in lacto acid bacteria drug products.

Acquired Immune Deficiency Syndrome (AIDS) virus
Acquired Immune Deficiency Syndrome (AIDS) virus Diameter: 1 ƒÊm

The pathogenic virus of acquired immune deficiency syndrome (AIDS), categorized into two types: HIV-1 and HIV-2. When infected, lymphocytes, which are a type of white blood cell, are continually destroyed, breaking down the immune system of the body and making it susceptible to infectious agents. HIV is known to be non-contagious through, for example, light contact experienced at the work place, school, or the household, and even through some extent of close contact. There are no reported cases of transmission through the coughing or sneezing of infected patients, nor through carriers such as mosquitoes. Proper public understanding regarding the routes of transmission and etiology of the disease is required.

Influenza virus
Influenza virus Diameter: 0.8-1.2 ƒÊm

The viruses that cause influenza (flu). They are spherical or tubular in shape, with diameters of approximately 80-120 nm, and are classified broadly into Types A, B and C. The reason that a global outbreak of Type A occurs about every ten years, is that it is contracted across various species, including humans, birds, pigs, and horses, leading to the birth of a subtype. In contrast, Types B and C only infect humans, thus there is no risk of a subspecies being produced. Although there is no effective causal therapy, it clears up naturally in about a week so long as no complications such as pneumonia arise.

Collagen
Collagen (Type I collagen) Diameter: 3 ƒÊm

A type of protein that makes up our bones and teeth, cartilage and intervertebral disks, blood vessels and skin, as well as cells. It is often added to health foods and cosmetics for its expected rejuvenating effects on the skin and hair, such as moisturizing the skin. Collagen makes up 20-30% of the total protein content in mammals, constituting cartilage and tendons. Type I collagen is a long fibrous collagen with a molecular weight of about 300 thousand, and length of approximately 300 nm. Adjacent collagen fibers overlap every 64 nm and pull on each other to maintain strength. The collagen fibers constituting tendons are said to have a strength equivalent to that of a copper wire pulled taut.

Yellow fever virus
Yellow fever virus Diameter: 40-50 nm

The name yellow fever comes from the fact that it attacks the human liver and causes jaundice. Records of this disease date back to as far as the 17th-18th centuries. At the time, jaundice was considered to be caused by bacteria, the dwellers of the micrometer world. The existence of the virus, more minute than bacteria, was experimentally proven by 1900, and a vaccine was developed in 1937. Since the development of the electron microscope in the 1950's, we have become able to visually confirm the existence of the virus instead of merely hypothesizing about it in the experimental world.

Silicon crystal
Silicon crystal Diameter: 50 nm

Silicon (atomic symbol Si), the substance found in the highest content in rocks on Earth. It is well known as a material for semiconductors, which constitute the heart of high-technology products such as PCs, cell phones, and digital cameras. The purity required of the silicon crystals used for such industrial purposes is 99.99999999%. Although silicon was originally just a semiconductor material, it has become a symbol representing high technology, as demonstrated by its use in names such as "Silicon Island."

Protein
Protein Diameter: 10 nm

A substance which makes up muscle tissue and internal organs, a substance fundamental to life. The English name "protein" originates from the Greek word meaning "primary" and "important." By identifying the structure of a protein, the potential opens for the development of effective new drugs responsive to that protein. In addition, as the properties of protein vary minutely among individuals -- as is seen in fingerprints, if the structure is revealed, then a type of 'order-made medical care' may be achieved. Protein is a substance that constitutes life, and which holds the key to the secret of life.

Dendrimer
Dendrimer Diameter: Several nm-<100 nm

The general name used to refer to macromolecular compounds (substances with a high molecular weight) having a spherical structure, with molecules connected in branches stemming from their respective nuclei. The name comes from "dendron (tree)" in Greek. It was first discovered in 1984. The size and properties of the molecule can easily be changed, thus it holds potential for application in diverse fields. For example, in medicine, it may be applied to drugs that remain undissolved until they reach the affected part, or used in artificial red blood cells, and in electronics/optics, to solar batteries and displays (screens).

Carbon nanotube
Carbon nanotube Diameter: 0.43-<10 nm

A cylindrical tube formed by carbons in a netted structure. It is about 1 nanometer thick, with a length several thousand times its thickness. It has a strength about 20 times that of steel, with half the weight of aluminum, and exhibits phenomenal tensile strength in the direction of the fibers. With these traits, it could enable cargo shipments between space and the earth, making it a technical innovation in which interest is growing. It is a 'dream substance,' whose diverse properties -- such as heat resistance to endure 2000 degrees Celsius under specific conditions, or highly efficient heat transmission -- could potentially contribute to resolving our energy problems.

DNA
DNA Diameter: 2 nm

The substance that determines the genetic information of all organisms on the earth. It is well known for its double helix structure, which enables it to replicate itself in order to transmit genetic information. DNA consists of the four bases of adenine, guanine, cytosine and thymine, the combination of which defines the appearance and constitution of organisms. A joint team of members from six countries had been engaged in an international cooperative effort to determine the complete sequence of the approximately 3 billion bases, and after roughly 15 years, on April 14, 2003, announced it had successfully mapped the human genome (complete genetic information of humans). This announcement came 50 years after the groundbreaking discovery of the double helix structure of DNA in April of 1953.

Nanoparticle
Nanoparticle Diameter: Several nm to several hundred nm

Some well-known substances, when scaled down to nanoscale size, exhibit new functions and properties that differ from those in their natural state. These substances are generally referred to as nanoparticles. For example, the nanoparticle of gold, or the metal gold (Au) downsized to the nanoscale, emits colors other than gold such as red and black, depending on diameter, thus can be used in applications such as laser-irradiated color markings. In addition, nanoparticles that scatter UV rays are used in cosmetic products, demonstrating the diverse areas of their application.

Fullerene
Fullerene Diameter: 7 A

A molecule consisting of carbon atoms bonded in a soccer ball-like structure. It is extremely stable, and is referred to as the "third carbon" next to graphite and diamond. Professor Kroto and his group who discovered it received the Nobel Prize for Chemistry in 1996. It is anticipated that it will be used in medical fields, such as in eliminating bodily active oxygen, which jeopardizes health and beauty, or in stopping the action of enzymes required by the AIDS virus for its proliferation.

Atom
Atom (Hydrogen atom) 1 A

There are more than 90 types of atoms (called elements). Each atom of an element consists of a nucleus with a specific positive charge, and a specific number of electrons. The hydrogen atom (protium), having the simplest structure of all atoms, is composed of a single electron orbiting a nucleus consisting of a single proton. In 1766, the British scientist/physicist Henry Cavendish became the first in the world to discover hydrogen. Later, the French chemist Lavoissier confirmed the generation of hydrogen from water, and named it the "hydrogen atom" based on the Greek words "hydor (water)" and "gennao (generate)." The word "atom" is traced to the Greek word "atmos (something that can not be divided)."

Amino acid
Amino acid (Glutamic acid) Several A

Organic compounds constituting proteins that are fundamental to the sustenance of life. There are more than 500 amino acids. Of these, glutamic acid, which is familiar to us as a synthetic seasoning, was named after the fact that it was isolated by hydrolysis from a protein called gluten found in wheat, by the German, Ritthausen, in 1866. It is a nonessential amino acid which plays an important role as a neurotransmitter in memory and learning.

Atomic nucleus
Atomic nucleus 10 fm

It is positioned in the center of an atom. Nuclear particles consist of a single proton in the case of the hydrogen atom (protium), and protons and neutrons in the case of other atoms. To demonstrate the scale, imagine the atomic nucleus amplified to the size of a golf ball of diameter of about 40 mm, in which case the atom itself would be roughly 400 meters, corresponding to the size of one hole in the golf course. It is a well known fact that in electric power generation, atomic energy is generated by splitting the nucleus of substances such as uranium and plutonium. The phenomenon of nuclear fission was discovered in 1938 by a German physicist Otto Hahn, who later received the Nobel Prize for Chemistry in 1944.

Neutron
Neutron 1 fm

An elementary particle which constitutes the atomic nucleus together with the proton. It is slightly heavier in mass (0.14%) than the proton. With the single exception of the hydrogen atom (protium), atomic nuclei consist of protons and neutrons. The neutron possesses a minute magnetism. It is utilized in nuclear energy-related applications, being a requisite for the activation of the nuclear power reactor. It can also be applied in analyzing the properties of substances, by hitting targets with a neutron beam and observing scattered neutrons. Potentially, it is being considered for other applications such as protein analysis in life sciences, and visualization and inspection of high-technology products in industry. The neutron was discovered in 1932 by the British physicist James Chadwick, who later received the Nobel Prize for Physics in 1935.

Proton
Proton 1fm

An elementary particle composing the atomic nucleus. It is the most fundamental component of matter, and was named the proton after the Greek word "protos" meaning "the first." The Japanese name is based on its positive (plus) electric charge. The proton can be utilized in medicine to treat diseases. For example, as the positive charge of the proton acts on the atoms (electrons) in the matter constituting the human body, the proton beam can be used to hit focuses such as cancerous cells within the body to treat them.

LSI (large scale integrated circuit)
LSI (large scale integrated circuit) (Cross-section diagram of LSI test pattern) Minimum line width of 55 nm or less

The latest generation of advanced electronic devices, including personal computers and cell phones, use integrated circuits fabricated with a minimum line width of as small as 55 nanometers. As the line width is decreased, the number of transistors on a semiconductor chip can be increased, resulting in dramatic increases in the chip performance allowing the electronic devices to be made more compact. Microfabrication technology plays an important role in achieving such highly integrated circuitry. In Nikon's IC Steppers and Scanners, which play a fundamental role in the manufacturing process of semiconductor chips, light illuminates a glass master plate inscribed with a circuit pattern to reduce the image of the master onto a semiconductor wafer, making multiple copies of the pattern. To achieve continued reduction of circuit size in the future, more advanced wafer exposure systems that are capable of 32-nanometer or smaller productions are highly desired.
