Brief History
Posted: Tue May 17, 2005 1:11 am
Hard on the heels of finishing the story of Isaac Newton I have been listening to A Brief History of nearly Everything by Bill Bryson on cd. It is marvellous, it explains very complex theories in an understandable manner. I might drop in the odd amazing factoid as I get through it but here is one to start.
We are probably all familiar with the representation of an atom, a neutron and a proton being circled by an electron, it's the scale of these drawings that is all wrong.
e.g. If the atom was magnified to the size of a Cathederal then the Nucleus (neutron and proton) would be the size of a fly, yet it would be 99.99999% of the weight of the cathederal!
