You were corrected- what you did to show your happiness was to move the goal posts from " there is almost no mathematics in chemistry apart from basic numeracy." to "beyond arithmetic, basic calculus, linear algebra and integral transforms" Nice try. Did you think we wouldn't notice. Why not just face up to the idea that you just slandered a profession because you didn't know what you were talking about? There is, for the record, a whole lot of group theory tucked away in there too.

It shows. The idea that " there is almost no mathematics in chemistry apart from basic numeracy." is absurd.

Thanks for pointing out 5 of the many occasions where science has corrected itself. I doing so you have shown its major advantage over some other "belief systems".

Broadly, the answer to you question is Here http://www.cochrane.org/

That depends on whether you take the legislation sensu strictu or more generally as being about the restriction of dangerous dogs. Often bought to show off. Not really needed. Likely to harm kids and others. Provides illusion of security Main argument in favour boils down to "but I like them". and so on. We won't get the wrangling about whether the 2nd amendment applied to automatics ; instead we get it about what's a pit-bull.

Even if we assume that these "Chinese herbs" are, in fact some guy's hedge trimmings, can anyone think of a reason why it's taken so long? Could it be that the hold-up is actually due to the fraud squad gathering evidence? Of course they could be some herb that contains a controlled substance which would explain the delay.

I always thought of them as personal resource enhancers. I guess it depends if you are buying or selling.

It's an animal that produces eggs and milk- it is therefore unusual in being able to make its own custard.

Does that make you a sonofabitch? I'm just waiting to this thread to turn into a photocopy of the "guns" debate.

I don't understand a word of Arabic. Is there anything there that mentions a university or a researcher's name?

Where did you find out about it?

Did you make those changes? Did they change the way they teach history? Has politics been re-written? No? Why not? Is it because we don't know if he was real or not? Well- that's the point I was making. The only sensible answer to this thread is "we don't know". And after 38 pages it's getting a bit silly.

What would you do different;y if the answer was not the one you think it is? What difference would it actually make to you?

Still less convincing than this explanation. https://xkcd.com/593/

It's true that the term is ambiguous- it applies to a variety of dogs. However the origin of the term is clear enough; pit bulls were bred to fight in bull pits. I'm puzzled by the claims that these dogs are not naturally aggressive- given that we bred them to be so. I'm also puzzled how come an animal which is claimed to be relatively non- aggressive is, in fact, disproportionately widely involved in acts of aggression. An obvious answer would be that there are some arseholes out there who encourage the dogs to attack- that seems quite a probable explanation for at least part of the disproportionality. But it just brings us back to my earlier point. You can't legally proscribe being an arsehole. Her's another thought for you; nobody needs a dog "designed" for bull baiting these days. Yet they seem very popular with some sections of the community. Does a dog with the misfortune to be owned by one of those neanderthals who want it to fight have a reasonable expectation of being looked after properly? Most of the suffering is not born by humans- but by the pitbulls who end up forced into fights and only kept as misguided status symbols. Are we being fair on them?

It's an interesting point; does it matter? Well, if you mean "does it actually make a difference to us" then we would know if he existed. For example, if my some strange means Jesus' existence made the difference that all left handed people would like cats then we would know whether or not he existed- simply by checking on the pet preferences of left handed people. If it made a difference then you could specify that difference by saying "if Christ was real then [whatever] otherwise [something else]", and we could look and see which is real . Is it [whatever] or is it [something else]? The idea that it makes a difference to us and the idea that we know whether or not he existed are logically equivalent. Of course, it may be that it will matter later- but that means we find out whenever "later" is. Here and now it doesn't make a difference; and we don't know.

Where did you hear about it? It's news to me.

I'm glad to see they stopped calling it Napoleon syndrome. Now all they need to do is realise that it probably doesn't exist. https://en.wikipedia.org/wiki/Napoleon_complex "If some of the little breeds were big they'd be downright dangerous and make pitbulls look soft in comparison. " ​Yes, but the point is that they are not big and they are not so dangerous.

Interesting plot: I don't understand it. I can see how there's an infinite set where a=b but that's not what was asked for (And I don't know what happens in the complex plane) I spotted 2,4 by inspection and I should have spotted -2,-4 by thinking about it.

Feel free to make a chihuahua as dangerous as you like. There really is a difference.

Yes.

Controlling the pressure will only control the flow if the viscosity is constant. Viscosities vary a lot with temperature. You ought to measure and control the flow directly.

Not really. There's the other tacit criterion but I thought it was too obvious to mention. Nobody needs a staffy.

Separating gases by density is very difficult. https://en.wikipedia.org/wiki/Gas_centrifuge What are you trying to do?

You don't know they are stupid until it's too late.
