toc Read here about a website that is organized around the powers of ten.

=Overview= CERN, the European Organization for Nuclear Research, maintains a "powers of ten" website explaining the nano-scale. Deliberately modeled on the Eames film, it zooms from 10^-17 meters to 10^26 meters.

=Texts From The Site=

10^-15
Protons and neutrons in the nucleus are made of 3 quarks. Quark interactions are studied at CERN to learn how particles formed in the very early Universe.

10^-14
At the centre of the carbon atom is a nucleus made of six protons and six neutrons. 99.95% of the mass of the atom is concentrated in this tiny space.

10^-13
Repeated text: The carbon atom, an essential ingredient for life, is mostly empty space. A cloud of six negatively charged electrons orbits the positively charged nucleus. From 10-10 m to 10-13 m not much changes.

At the centre of the cell is a tightly coiled molecule called DNA. It contains the genetic material needed to duplicate the fly.

Welcome to Powers of Ten. Travel across the Universe. Changing scale by just a few powers of ten dramatically alters your perspective.

Your journey begins in the garden of the Microcosm visitor centre. This is the scale we know best - our own. Zoom in and out in powers of ten using the ruler.

Which other planet is the same size as the Earth? Mars? Venus? Jupiter?

The moon's orbit aound the Earth, the furthest humans have ever travelled.

Four days of the Earth's orbit.
