yeah!! pshhhaaa how TOXIC could thallium be... come on.

Wikipedia says:

"Because of its use for murder, thallium has gained the nicknames "The Poisoner's Poison" and "Inheritance Powder" (alongside arsenic).[3]"

"Thallium and its compounds are extremely toxic, and should be handled with great care. There are numerous recorded cases of fatal thallium poisoning.[44] Contact with skin is dangerous, and adequate ventilation should be provided when melting this metal. Thallium(I) compounds have a high aqueous solubility and are readily absorbed through the skin. Exposure to them should not exceed 0.1 mg per m2 of skin in an 8-hour time-weighted average (40-hour work week). Thallium is a suspected human carcinogen.[45] For a long time thallium compounds were easily available as rat poison. This fact and that it is water soluble and nearly tasteless led to frequent intoxications caused by accident or criminal intent.[18]"

"Among the distinctive effects of thallium poisoning are loss of hair (which led to its initial use as a depilatory before its toxicity was properly appreciated) and damage to peripheral nerves (victims may experience a sensation of walking on hot coals). Thallium was once an effective murder weapon before its effects became understood, and an antidote (Prussian blue) discovered.[3]"


No more than 100 micrograms per square meter of skin per 8 hour work day !!!!

US Marine Corps Flamethrower Demonstration

NordlichReiter says...

Common misconception is that when a flamethower is shot and punctured that it will explode. It doesn't explode, but it can cause a large fireball. Which often looks like an explosion....

Read this Discovery forum post on the Myth of exploding flamethowers.

The quoted person below can explain what I mean far better than I can.


Not to split hairs - oh heck, yes, let's do that.

The word explosion is what's wrong. Used here it's a pardonable exaggeration, but an inaccurate statement nonetheless.

I'm going to use a US WWII M2 series flamethrower for discussion purposes. In it's original form, it used hydrogen for its compressed gas element. Hydrogen can explode when exposed to air and flame. However, they quickly switched to nitrogen, which is generally inert. If a bullet hit the nitrogen tank, no explosion.

As for the fuel, it's a thickened gas, just like napalm. It doesn't explode in its liquid state, and it doesn't vaporize to any degree worth mentioing here, so no explosion there, either. It burns. Period.

The pressurized nitrogen tank provided the 'push' for the fuel to be projected. If the pressure valve was turned off, and the thickened fuel tank was hit by a bullet, no fire or explosion, for the same reason a gas tank doesn't burn when shot. It needs to be exposed to air before burning, and there is none inside the tank. With an unpressurized tank, you'll get a slow leak (it IS thickened fuel, remember) which may eventually find an ignition source. The result: a fire, not an explosion.

If a fuel tank is hit when the pressure valve is on, still no explosion for the very same reasons. However . . . the thickened fuel is under pressure and will spray all over and is VERY likely to find an ignition source very quickly in combat. You still don't get an explosion, but you do get a big, spectacularly horrible fireball.

For purposes of conveying the horror involved, it may be understandable to misuse the term explosion. But for the purpose here of understanding the mechanics, explosion is not the correct word.

How to Read the Market's Expectations for Inflation

marinara says...

ok, i hope i can piss everyone off quick here, but TIPS are a rip off, they have nothing to do with inflation. period.

http://www.shadowstats.com/inflation_calculator?amount1=100&y1=2008&m1=8&y2=2009&m2=8&calc=Find+Out

Let's be straight here, I am accusing the government of cooking the books. Anyone who believes government inflation data (the video included) is a... (insert your insult here)

So basically we have the shadow statistics site saying inflation is real, and we have the TIPS value, which says it isn't.

I'm watching the video again, the dude never explains why the difference is expectation of inflation, just that it is. No doubt he'd give some circular logic explanation anyhow. ... Ok he explains, its the "market" that moves these things. Never mind that the FED is buying these things, and the FED isn't a market, it can move the treasuries however it likes.

Anyhow i won't downvote even though it is crap, after all i'm just a layman.
