Re: Non-alcoholic Flambe

This is quite an interesting question. AND YOUR ANSWER S ARE DANGEROUS AND STUPID Flipping through chemical abstracts does not make you a food scientist. Reading a line about LD 50 does not make you an expert in toxicology. You want to risk damaging yourself, fine, go have fun. Do not serve adulter...

Re: Civilian Avionics

Three small points no-one else seems to have mentioned yet: 1. It's no good saying that your minimum ceiling is 10,000 ft AMSL. You need to work out your target ceiling to a slightly finer resolution because it affects your choice of electronics. High altitude operation affects the reliability of el...

Re: Non-alcoholic Flambe

This is quite an interesting question. Essentially you want to know of a chemical that is fairly flammable, has low toxicity, and probably a boiling point well below 200°C. It should ideally be less intoxicating than ethanol, and should not taint food. (Oh, and also cheap!) This is something of a ch...

Re: Why are there so few great apes?

There's yet another very simple reason. The larger that typical members of a phylogenic division are, the less speciation there tends to be within it. Here's a ref: [cite] Generic species richness and body mass in North American mammals: Support for the inverse relationship of body size and speciati...

Re: Code Bowling 2 - Obscurity Encryption Challenge

The following works pretty well if the victim can't inspect the code carefully. I can't claim it is completely original; something very similar has actually been done by a real vendors in the past, in response to pressure from intelligence agencies. ROT-13ed, of course, to avoid spoilers!! P = R( U(...

Re: Negative numbers to non-integer powers

If we raise a negative number to a positive, non-integer power we get a complex answer, e.g. (-0.5)^{6.5} = 0.011045... i If we instead square the orginal number then raise it to the old power divided by 2, we get a real answer: {(-0.5)^2}^{3.2} = 0.011045... What's gone wrong? Pres...

Re: 0848: "3D"

I saw Jaws 3-D at the cinema when it came out back in 1983. (Yes, it was a polarizing glasses 3D film, just like we have today, except that the glasses were disposable.) I can see 3D effects just fine, and they don't make me ill. What they do make is bad movies. Well, that's too harsh; usually, they...
