When not programming I spend much of my free time avoiding the task of writing bios.

Currently having some fun with lock-free mutable collections at http://hackcraft.github.com/Ariadne/

comment Could we send a man safely to the Moon in a rocket without knowledge of general relativity?
"Dead reckoning" was in use for at least two hundred years before the explanation that it was short for "deduced" was arrived at. It's more likely in contrast to the continual "live" data one has in using stellar navigation (this being when people navigated by celestial bodies, rather than to them), since dead reckoning was used when that wasn't available. The first attested use points out the contrast; "Keeping a true, not a dead reckoning of his course."—Mark Ridley, A short treatise of magneticall bodies and motions, 1613.
comment How do microwaves heat moisture-free items?
If you are going to do this experiment, be careful as to the plastic you use; some (e.g. the melamine used in "unbreakable" plates and cookware) will not only heat up considerably but can also crack explosively and/or release formaldehyde. Stinks up your kitchen for ages.
comment How come squeezing a water bottle makes the water come out?
If the volume is constant, why can you not squeeze a bottle as much with the cap screwed on?

comment Why does Stephen Hawking say black holes don't exist?
"Most physicists foolhardy enough to write a paper claiming that “there are no black holes”...would probably be dismissed as cranks". Unfortunately, most journalists writing such a sentence, and burying "at least not in the sense we usually imagine" as a parenthetical cop-out, would not be dismissed as cranks. If modern journalism had been around when it was discovered that planets weren't "wandering stars", it would have been reported as "top astronomer says planets don't exist".
