Thanks for that site. It tells me that because of Skitt's law this post, which tells you that you put too many capital letters in "You're missing a Definite Article, an Apostrophe, and a Period. ", will contain at least one grammatical error.

It's not what I'd call trivial.

I think this is the only one that will make much odds to me.

Filter the solution while it's hot (obviously, this might be tricky). That way you remove dust and such that can act as a nucleation point.

Rinsing hair with acid would not only be stupid from the obvious point of view, but it wouldn't work. Adding acid to soap or the scum formed from soap and hard water peoduces a greasy mess of fatty acids.

IIRC ptfe melts at about 325C and you fry things at about 250C.

Over the last few months it has stopped being late Summer/ early Autumn and is now Late Autumn/ Early Winter. On the whole this has been accompanied by a fall in temperatures.

I predict that this trend will reverse in a few months' time.

I also predict that night time tendst to be less well lit than daytime and that rain is generally wet.

The simplest is to use an ordinary pipette. You time how long it takes to empty and the time depends on the viscosity.

Don't forget that viscosity is usually strongly dependent on temperature.

It isn't.

Tetrafluoroethylene is a gas.

Polytetrafluoroethylene is a thermoplastic.

I can't help thinking that the problem is not that a foolish man said something foolish, but that somehow he gets to say it on national television.

A neon atom, a more or less free positron and a citrate ion.

The positron is kicked out at a huge energy and will plough through the material bouncing round until it loses most of that energy. Then it will anihilate whatever electron it hits and form a radical ion. If it happened to destroy an electron that was part of a citrate ion it would produce a citrate radical, but it's more likely to make H2O+.

Re

"If there isn't enough evidence to convict them, what makes anyone so sure they are the "worst of the worst" anyway?"

IIRC the answer is that the commander in chief of the millitary (who will be running) the "trial" said so.

It's easy for the army lawyers because their boss already pronounced these men guilty. Finding them not guilty might be judged as insubordination and they are not going to risk that.

It's possible

Two thirds of the earth's surface is covered with water and 88% of the mass of that water is oxygen.

(things may have been a bit different back then, but oxygen wouldn't have been rare)

The radiation hazard from a personal fusion reactor might be tiresome.

" i saw all the scientist wonder in amazement over the giant gypsum crystals.

Is it really all that suprising that there are giant crystal caves?

"

Scientists are allowed to have emotional responses to beauty; understanding the geology doesn't detract from that..

No.

Are you trying to dispose of it?

If so the simplest solution is to take it somewhere away from people and buildings etc and set fire to it carefully. Obviously you need to do this somewhere where a fire will not uspet anyone.

The official way would be to get some hazmat company to take it away.

Sound is a form of energy andthe conservation laws require it to be emited whether there's anyone to hear it or not.

Incidentally re

"Aristotle loved empirical research,..."

and

"He ended up at some of his crazier assertions by extrapolating from "common knowledge."

Which do you mean?

Extrapolating from known to unknown is hardly empirical.

"sometimes the easiest way to get an answer was to actually look."

Aristotle is noted for saying that spiders have 6 legs (or was it flys have 8).

Is this a homework question?

Does it feel the same too?

I have never asked it. To be honest, I wasn't really aware it had feelings.

I thought the comment in the HHGTTG about the "small green pieces of paper" not being unhappy was a joke.

I think that you could replace a significant part of the cellulose (perhaps the majority) in paper with nitrocellulose and treat it so that it feels close enough to the same as paper that nobody would spot the difference unless they happened to spend a lot of time feeling banknotes.

"It is doubtful that nitrocellulose could pass as regular cellulose anyhow. "

What's your second guess?

Gun cotton looks a lot like cotton; flash paper looks a lot like paper.

I think that when the scriptwriters chose urea they were taking the piss.

About 1000 times less KCN will do it too.

Come to think of it, the only way to inject just oxide ions into someone would be to put them in the path of a particle accelerator. Given time that would shut down their cell chemistry too.

The easiest way to shut down someone's cell reactions is to wait. Typically 100 years will do the job. It has the remarkable (in most cases, unique,) advantage of being legal.

If urea were explosive then toilet cleaners would be in trouble.

It's a totally bogus story.

I thought that one of the problems might be that everyone would think of you as "the permanently late guy who can never plan his schedule so he ends up running all the time". People would look at you as if you were an idiot because they might reasonably think you were an idiot.
