Atoms in Your Head
How many atoms does it take to fill my head?
———- from David Lockwood ofDundee, Scotland
How small is your head? What kind of atoms are you talking about? Uranium atoms are much, much larger than, say hydrogen atoms. If your head were full of uranium, it would be very heavy – much heavier than the vacuum that’s in there now. It also might be radioactive and, if it were filled with plutonium, uranium’s evil twin, it would glow in the dark. Imagine that! Some guy wandering around Scotland, wearing a kilt, holding a bagpipe, struggling to keep his heavy, glowing head between his shoulders. No wonder you people believe in the Loch Ness monster.
