I was a chemist long ago. One of the rules of chemistry was "conservation of mass." The mass before and after a chemical reaction is always the same. I asked my professor once, "If a reaction gives off heat, then matter must be consumed, right? Even if only an immeasurable amount." He said...

Because a lot of Americans dislike France for a number of reasons. He's a rednecked goober. People laugh at guys like this.

It's a lot easier than it sounds. The feeling is exactly the same as you get in a powerful elevator. You FEEL yourself going up. You keep working the glider to the areas of greatest lift. I had students finding thermals in just a few hours of experience.

May I suggest they "fix" this VERY quickly, as those sorts of cockpits are dangerous.

DF, your replies are juvenile, and barely worthy of reply. Again, the topic is Hitler. American atrocities are utterly meaningless, and off topic. How do American atrocities affect what Hitler did in history? They don't. And because some Americans at some time did something like My Lai...

Just an idiot with a stencil machine. Don't turn it into something it's not.

That sort of know-it-all jerk captain is rare these days. FO's will not tolerate it. If I had been the FO, first I would have told him to shut up; secondly, I would have physically intervened when it became dangerous.

Imagine the Christian craziness in the year 1,000. They must have been severely bummed. 1,000 is such a better number than 2,000. I am a Christian and so am allowed to say "Christian craziness." ;)

A laughable rebuttal. Poll the people of Tibet and Taiwan, and get back to me.

There's nothing wrong with the question... it's a matter of physics. Now if he said "I want to drop a gigaton bomb on country "B" and kill 'em all" then yeah, there are issues. The answer is yes, it is theoretically possible. But it'd never get airborne, being too massive. Big hydrogen bombs...

Two ways - by devices called Variometers, and by feel. A vario is just a sensitive vertical velocity indicator. Some of them are audio so you can keep eyes out and locate the lift more safely. When you enter an area of lift, the vario tone changes, and the pitch of the tone goes up as your...

I'll admit I was shocked, but they do in fact import TONS of coca leaf... extract the cocaine, use the rest in their drink. I guess cocaine is legitimately used as a local anesthetic in medicine. I hear you on the flavors of alternate colas. Honestly, I don't drink sugared coke any more...

Unless they get the unique coca flavor from the infamous South American coca plant, all these "Colas" are pale imitations of the real thing, Coca-Cola. There is no Cola flavoring at all in Coke. Now, someone is certain to say "They don't use coca in Coke any more!" Google it. They still...

I think the videos showing the street fighting was the battle for Hue.

Good pictures.... shows the brutality and anguish of this terrible war. I remember as a kid hearing about Vietnam on the news, but I was too young to really understand. One thing I find interesting are all the "custom touches" the soldiers and airmen put on their uniforms. Stickers...

From der Spiegel, a leading German news organization:

Old thread, but congrats to China for her expanding space program. Valuable as fusion fuel? Someone has a functioning fusion reactor? :woot: The USA is fortunate to be a primary helium exporter for many years, but new wells in Algeria and Canada are coming on line. Helium is...

OK this is kind of odd... I can see a twisted humor here. But if some dude charged me with a baton in the USA, I'd kick his rear end up and down. And someone else would probably pull a gun and let him have it. How are you supposed to know he's not serious? That's like driving up to someone...

The now infamous "lesbian kiss" is all over the news here in the USA. Years ago, it'd bother me. Now, I couldn't care less, so long as the person can do the job, what business is it of mine?

It will never be possible to prove that a Creator exists. It's not about free choice so much as free will. We are created with the ability to accept or reject God. God does not want mindless drones; he wants followers to examine the evidence, and choose to follow Him freely. We are creatures...
