There seems to be a fair bit of evidence that the "tea party" is, among other things, anti science. I may be wrong, but I think that science drives the progress that will get us out of the recession and ensuring that children at school get a good education in science will help to maintain our standard of living. I conclude that the Tea Party's ideas are the last things that would get us, and keep us, out of recession.

Practically whatever you do to the building, it won't topple like a tree. Gravity goes down, and so do buildings. They are not stiff enough to fall over except in cartoons. The "controlled" bit of demolition is a matter of wrapping it and making sure it happens as cleanly and safely as possible. I might not notice if the maintenance bloke s stacked tons of thermite or explosives in the building where I work, but the maintenance blokes would. So would the plumber who turned up the next week, or the computer bloke, trying to trace a wire. Someone would spot it and call it in. (actually, it probably would be me; I'm a Safety Rep and I get interested in that sort of thing.)

Then you should have followed the link in the 4th post in this thread. and It is indeed about persistence of an argument. If you persist after it has been proved that you are wrong then, at best, you are a fool.

In "Dave world" that report is damning evidence. In the real world, however, it's just silly. If the stuff ignites at 430C then how come it didn't ignite when it was in the middle of a burning building? Do you understand the significance of that fact? It means that this "magic" stuff simply didn't work. I don't know if you can watch this; it may be limited to the UK. http://www.bbc.co.uk/iplayer/episode/b014gpjx/9_11_Conspiracy_Road_Trip/ however one of the things they do is show what happens if you ignite several pounds of thermite resting on a steel girder. The answer is nothing. It melts and runs off. They also ripped apart quite a lot of the other "evidence" for the conspiracy. Needless to say, most of the conspiracy theorists didn't accept the evidence of their own eyes. I wonder if it's time to close this thread.

Yes, provided that the water is in the form of steam and the iron is finely powdered and very hot. So, from any practical perspective, no. A hot solution of washing soda in water will also produce hydrogen if you add Al foil. It's a bit less nasty than lye.

LOL

The problem is when, after 5 months, you have not realised that you are talking about different dots.

"CAN Gold somehow affect the female body in a positive way"? It depends what she does with it, but I'd imagine it's a bit cold.

This isn't a development because it can't go anywhere or do anything. It's not "supposed" impossible; its proven impossible. It would be better if he spent his time helping little old ladies across the road or, at least, trying to do something where he might succeed.

Most yeasts are not happy outside the pH range from about 3 to about 5 so they are not very tolerant.

"IF we use mass, the force between an electron and a proton will be nearly 1837 times the force between two electrons " But it isn't; so you idea is wrong.

"This post has been edited by crow5derlock: Today, 01:05 AM" Why? Still, at least it's a better typeface.

OK, and now once more with feeling! Try 179 degrees ( this might be a long thread)

The zinc would melt and the brass (which already contains zinc) would dissolve in the molten zinc.

Does the question also say "ask people on the net to answer this for you"?

I know that, and you know that but I suspect that there's someone else here who doesn't know it (yet). However I'm sure someone will find it in amusing challenge to find the flaws in the argument (they have already started) I wasn't kidding about this being the equivalent of proving that 3 is an even number. The crassly oversimplified version is that you can find square roots with a straight edge and compasses, you can find the square roots of square roots too. In fact you can find any 2^nth root by repeating the process. But 3 isn't of the form 2^n (not least, because all such numbers are even apart from the trivial case of 2^0). You need to be able to solve a cubic equation to trisect an angle and you can't solve cubic equations with only even powers. So, if he proves that he can trisect an angle, he has shown that 3 is an even number. However notwithstanding reality, I confidently predict that the OP will triumphantly bring forth the 4th part of his series: which will be tosh. (Incidentally, I know that's a dumbed down version but it does make it clear that you are probably wasting your time trying to double a cube or trisect an angle. The full proof that it's really impossible is on the web (isn't everything?) if you want to look for it.) The hand waving argument proof has the advantage that the maths isn't difficult. Many people are not that familiar with Galois and his work.

I did this when I was a kid and nobody would give me any sulphuric acid to play with. I used a carbon anode. Simply boiling the solution will drive off most of the water. The normal safety remarks about boiling sulphuric acid apply.

Should we sell tickets? The point is that since it has been proved impossible, all you will do is post up an error of some sort. There's every chance that someone here will spot that mistake.

Where did the powder come from?

Talk about "is such and such harmful" should always include some mention of the circumstances. For example, propped up on caffeine, I can finish this report that the boss wants tomorrow morning. Without the caffeine, I will fall asleep, not finish the report; get sacked , have no money and so I will starve. Caffeine is clearly good because it avoids starvation.

The proof of the trisection of an angle is mathematically equivalent to proving that 3 is an even number. Do you really want your first post here to say "I think three is an even number!"?

I don't think that ferricyanide will do; you would have to use potassium cyanide and that's not nice stuff or easy to get. The traditional way to make thiocyanates is from sulphur and cyanide but that''s not something for an amateur to play with. I think your best bet is the photographic suppliers or ebay.

This may seem like a silly question, but will sodium thiocyanate not do the job? I can't easily see how it could make a difference to the grain size. I'm pretty sure that the whole of the silver halide crystal gets converted to silver during development so the grain size is set by the size of the halide crystals. However if you want to you can make it from KOH and NH4SCN band then remove the ammonia by blowing air or nitrogen through the solution.

Fundamentally, if you need to ask questions like "what woud be the best oxidizer to use in a solid fuel rocket using margerine and sugar as the fuel? " then you shouldn't be playing with rocket fuels. Leader Bee's post is largely garbled nonsense.

That looks like a contradiction " not to an infinitesimal size is removed." "Not all the guests can keep being compressed indefinitely." Why not?
