On general matters my young and very beautiful wife seems tho think that "Best before" and "sell by" actually mean "Deadly Poisonous immediately after" - thus any item out of date is hurled into the trash  - anybody else suffer this or have any tales to tell?

Physics, Astronomy & Cosmology / Effect of nuclear explosions in space?

« on: 03/06/2009 21:03:28 »

Bored chemist,

Please explain how the energy radiated by a nuke would move 'vapour away' ?

It would heat it from one side only. As for the first answer, the momentum of the bits of the bomb is due to the conventional trigger and not the nuclear 'blast' -

Well I'm not sure whether mythbusters are watching but if they are....

Nuclear weapons splitting comets into millions of bits - BUSTED!

Physics, Astronomy & Cosmology / Effect of nuclear explosions in space?

I am a little puzzled by the idea of destroying comets using nuclear war-heads. As far as I can tell nuclear explosions occur on earth by merely producing an intense burst of energy which superheats the atmosphere, and thus causes rapid expansion of the air, after a few seconds cooling begins and the atomic 'wind' reverses in direction. In addition to this there is the intense heat/light radiation across a wide spectrum.  apart from possibly melting the surface of a comet/asteroid can anybody explain why so many people think a nuclear explosion would disintegrate such an object?

Conventional explosives (black powder derivatives excluded) detonate ie turn from a compact solid into gas and thus produce a real blast wave, using conventional explosives would be far more effective.  Of course I might have missed something in my understanding,   discuss?

General Science / Can I recreate the Dead Sea in my bathtub?

If your bath is downstairs and on solid foundations you could recreated the dead sea bouyancy by filling it with mercury. If not try custard or sugar syrup.

Some Mineral water (in the UK) firstly claims to be 60 million years old then suggests
it should be sold by a specific date (usually within 6-8 months)

I guess they got that out of the ground just in time!

Know anymore obscure sell-by / best before stories?
