And that is exactly what you set out to do with a definition. If I define mammals as; having live young; giving milk, and having hair I have defined all of them (pretty much) even though there are many of them. You don't seem to be able to explain what you are asking or you don't seem to understand what you have asked..

Well, for a start, I think I can prove that it is absent in, for example, flowers. As far as I can tell, a flower may turn to face the Sun, but it isn't because it "wants" to subjectively. There is no mind of a flower making a choice. A flower might react to being cut, but you can't sensibly call it a pain response. Who experiences that subjective pain? The flower doesn't know that it's a flower, so it can't know that it's a flower that hurts? I think I could make the same point for an earthworm. If it gets damaged, it reacts, but what entity subjectively experiences pain? The worm can't for much the same reason that the flower can't. Somewhere between humans and earthworms there must be some sort of cut-off and, if I'm right, that cutoff is the limit of self-awareness. If you don't know you exist, you can't know that you are in pain. That is testable (though it's controversial) http://en.wikipedia.org/wiki/Self-awareness#Animals

I still think you will find that the word "everyone" fits the bill quite nicely.

I'm not sure I need an argument to refute an unevinced assertion like "animals are sentient and have interests".

Embarrassed about forgetting Pi day? Concerned that your geek credentials might be in question? Try this easy solution! Wait a week and a half then announce that it's pi day all over again. Pi = 3.243F6A8885A308D313 from http://calccrypto.wikidot.com/math:pi-hex Brought to you by the letters A to F and the number 16

Or. perhaps, you are just wrong a lot. "There isn't necessarily a word that defines anyone" I think you will find that the word "everyone" fits the bill quite nicely.

It was the TV series I had in mind http://en.wikipedia.org/wiki/CSI:_Crime_Scene_Investigation though I guess the movies are much the same. The show uses a "rose tinted glasses" approach to forensic science. Remotely turning on the "Bad Guy"'s mobile 'phone to find out where he is would be exactly the sort of thing that would happen in the show. Unfortunately, it doesn't happen in real life. (Just think about it; nobody's mobile 'phone would stay stolen for long)

The EU is not planning to legislate for equipment you already own. So your new phone requires one charging voltage. your new personal training logger requires the same your new personal camera/projector requires the same again.

"Is Mutation Directed?" Roughly a third of is get cancer so it seems the answer is that , if mutation is directed, it's clearly not directed in our favour.

You have 200 or so posts and a rep of minus 120 odd. Looks like you are well placed to talk about ego.

Did you see that on CSI or something?

Atmospheric oxidation of glycerin will produce acid products. Also, trying to measure the pH of poorly buffered solutions with pH paper or an ordinary pH meter is very unreliable.

I suspect (but can't cite evidence for it) that the work function or the melting point might be a better indicator of how well the metals resist gallium. I'm also rather inclined to doubt that the Xtal structure makes that much difference (except indirectly) because i think the attack takes place at Xtal boundaries.

I'm shocked that nobody cited this yet. http://xkcd.com/927/

Since time doesn't exist, can you give me next weeks lottery numbers please? Thanks

I think congo red is probably pretty stable. On the other hand the Merck index says it's colour changes with the solvent. So you might be looking at something like a solvatochromic effect. A much simpler explanation would be a pH effect. Is the mixture buffered to keep the pH constant?

"you can only give me links" Obviously, this is a web page, not a convenience store. We can't send anything but ones and zeroes. If you want a physics book (and I think that would be a good idea) try Amazon. "but none of you can explain anything" We can, but you won't listen. instead you make absurd allegations about the whole of science being fraud. "Relativity is just perspective" No, it is, among other things, the reason why your GPS works.

If he answers I guess we will both get to find out.

I'm pretty sure that DMF DMA is a well known reagent. For example, http://www.mn-net.com/tabid/10229/default.aspx and that material is the next homologue. But that seems a rather odd reaction. http://en.wikipedia.org/wiki/Claisen_rearrangement#Eschenmoser.E2.80.93Claisen_rearrangement

What reaction?

"I think this is an unnecessary splitting of hairs. European individuals are those whose ancestors have their point of origin in Europe. This definition is actually very robust" Are you sure about that? I'm fairly sure that all of us have ancestors based in Africa. http://en.wikipedia.org/wiki/Recent_African_origin_of_modern_humans It's an interesting topic, but it needs some very clear definitions to get anywhere.

What colour is a "european" today? I rather suspect that there may now be more black and brown skinned people living in what is currently Europe then there were 5000 years ago in which case the "average" colour is darker than it was. Or are we talking about the group who get called "white" or (even more absurdly) "caucasian" ? If we are, is this in danger of turning into something that looks like the opposite of a "no true Scotsman" fallacy? (We are only counting white people so they are, by definition , just as white as they always were.)

pardon? (Though, for the record, biphenyl is clearly aromatic with 12 electrons; but they are in 2 rings.

I doubt you could sensibly aspire to predict it. On the other hand, you could do what I did and google the phrase "gallium attacks platinum". But that's hardly the point. Why did you post something as a fact when you hadn't checked it was right and, as you say, you had no way to know if it was correct?

As specified, it has 1 sf. However 5.00 degrees has 3sf.
