HOW hard you try you will never be able to grasp just how tiny, how spatiallyunassuming, is a proton. It is just way too small.

A proton is an infinitesimal part of an atom, which is itself of course an insubstantial thing.

Protons are so small that a little dib of ink like the dot on this i can hold something in theregion of 500,000,000,000 of them, rather more than the number of seconds contained in halfa million years. So protons are exceedingly microscopic, to say the very least.

Now imagine if you can (and of course you can’t) shrinking one of those protons down to abillionth of its normal size into a space so small that it would make a proton look enormous.
