Bill Bryson visits the Large Hadron Collider

The amount of precision required is pretty breathtaking, Gillies tells me. I worked it out mathematically, out of curiosity, and I can tell you that getting two protons to collide is exactly equivalent to firing two knitting needles from opposite sides of the Atlantic Ocean and having them strike in the middle.

(This probably is as good a time as any to mention again Bill Bryson’s wonderful A Short History of Nearly Everything.)
