The traditional "natural" remedy for tiredness is sleep. People say exercise works too, but I haven't checked it out; I prefer caffeine.

According to this http://www.ornl.gov/info/reports/1973/3445605501588.pdf salt water has a lower heat capacity (measured by weight) than fresh water. (page 8 has graphs of heat capacity vs temp for different salinities.) Even for a 12% w/w solution the change is only about 14%. Also, the method used isn't well designed. If you had the same mass of brine and fresh water and compared the rates of temperature loss of each you would get a better view of the effect. In this case you have different amounts of materials cooling.

Perhaps the difference just isn't big enough for you to detect?

"isn´t allowing it in any circumstances just giving a green light for all torture?" No http://en.wikipedia.org/wiki/Camel%27s_nose But it's still easiest to maintain the moral high ground by simply not doing it. Incidentally, is a government's use of the threat of torture the counterpart to the terrorist's threat of terrorism? Both don't really achieve much; both make you look like complete s***s, and both rely on fear.

So does my big neutronium hammer.

My opinion is that it won't work. In the boat example you cite you measure the speed wrt the lake. Without a lake you can't do that.

Detonating an antimatter bomb high above a city?
John Cuthber replied to Fanghur's topic in Modern and Theoretical Physics
So would I which implies that Dan Brown did indeed screw up on this (at least in the film; I don't remember the book doing that, but it's a while since I read it.) -
I'm hoping for a 2nd hand LC/MS system, but thanks for the support. (If it is rohypnol then an LC/UV might well do the job. The nitrophenyl group has a strong characteristic absorption) Incidentally, I'm still puzzled by this "Im aware cameras exist. Though i would (if i was to use a camera) use a more secure camera than a nanny cam) ALTHOUGH I HAVE VERY LITTLE EVIDENCE" Get a camera and get the evidence. Then you can get the police (who are a bit more likely to have access to a lab than you are- no matter how incompetent they might be.)

Detonating an antimatter bomb high above a city?
John Cuthber replied to Fanghur's topic in Modern and Theoretical Physics
The yield you quote is from uranium fission. Antimatter annihilation will probably be different. In principle I think all the energy is initially released as high energy photons. Those will hit the air and heat it providing some sort of shock wave and EMP. In any event, a bomb that you just have to get a few hundred feet away from would be pretty trivial by the standards of WWI never mind some sort of sci-fi super-weapon. -
You seem to overlook the fact that there are a practically infinite number of lies the torture victim can tell. Checking each of them is a major problem because there are a lot. It's not possible to know if the prisoner lied because Mr B-L is mobile. Incidentally since you can (in principle) do it by checking each house in turn it's very clearly a P problem not an NP problem; if you are going to drop things like that into the discussion, make sure you know what they mean. I can't see what "In short, you are all wet." really adds to the discussion. Would you care to expand on it?

I still think nec 209 should take his toenails to the doctor.

Is this statement " a multiple choice poll will never have every possible choice. " A true B false C meaningless D none of the above.

They often talk about thinks like the "90% surface" which is the shape that the electron has a 90% probability of being "inside" at any given time.

Acid catalysed dehydration of the cellulose. Roughly the equivalent of caramelising sugars.

Tell me michel123456, Are you a doctor or a dietician? Presumably you must be a really good one to make a diagnosis of a problem you have not actually seen.

If you have enough money, I will do it. I'm an analytical chemist with 20 years experience. I have done food analyses and I have analysed for drugs ( though not actually in food), I studied chemistry and pharmacology. The trouble is I don't work in a lab these days so I'd need to buy or rent the equipment. Do you have roughly £100,000?

Scopolamine might be better than torture, but it's still profoundly poor. The essence of the problem is that it's a hallucinogen. The prisoner is likely to talk, but he's as likely to talk about the big green hairy monster climbing up the wall as about his army secrets. Sure people talk a lot while high on versed ( or weed, come to that), but there's no way of knowing how much of what they are saying is bollocks.

This stuff's probably not good for you, but it's a free radical on sale in glass bottles. http://www.sigmaaldrich.com/catalog/ProductDetail.do?D7=0&N5=SEARCH_CONCAT_PNO|BRAND_KEY&N4=G307|ALDRICH&N25=0&QS=ON&F=SPEC Of course, so's oxygen, but that's too easy. Dimethyl mercury doesn't react with water and isn't spontaneously flammable in air so it's not that reactive. (though it is very nasty)
-
The third option "this didn't really happen" is missing from the poll.
-
If Scopolamine worked then nobody would bother with torture.

explosion dynamics as fractile patterns
John Cuthber replied to 36grit's topic in Modern and Theoretical Physics
I was a bit worried when I saw the OP couldn't spell fractal; but I completely gave up when I read this "through out all of reality and beyond. ". -
Haha. The bladeless fans work by shifting a relatively small volume of air at high speed and using that to move lots of air. Doing so is not very efficient (and an inefficient fan warms the air more that necessary which is not what you want.

Bible law exceeds God’s “Eye for an Eye” law.
John Cuthber replied to Greatest I am's topic in Religion
"Not Found The requested URL /quarterly.God'sSettledWord.Lesson13.pdf. was not found on this server." So they really don't exist for me. Incidentally, are there any cardiac surgeons or pathologists or whatever on the site who can vouch for the presence of these rules? -
Bible law exceeds God’s “Eye for an Eye” law.
John Cuthber replied to Greatest I am's topic in Religion
"Seriously, where can I find "God's laws" if not in the bible? Well. If you are a Bible believer, then you should kow that it tells you that God's laws are written on, or is it in, your heart." I'm not. Does that mean that , for me, those laws don't exist?
