    Great graphics. Still find it hard to believe Quantum theories are now being taught in schools. I could not get my head around how neutrons, protons and electrons work whilst at school over 30 years ago. Still don't really. I still can't conceptualise quarks and string theory and i've read about it - a lot. But it's now being taught in schools. Who said school childern are thick these days. If they can understand this new stuff they must be geniuses.

    Wowser !!!
     
  4. I like it.

    Makes you appreciate that, within a few powers of 10, and who is arguing, the ratio of the diameter of the human head to the size of the top quark is the same as the ratio of the distance to the edge of the known universe and the diameter of the human head.

    I think that stat. makes me appreciate how small the top quark is!
