Bush had a coin that had, "Invade Syria" on one side and "Invade Mars" on the other side. He flipped it, and you know the results.

Not just ordinary academics, British academics.

OMG, I hope you are kidding.

Who did he hire, Dumb and Dumberer Bindery?

In this case it was a crime.

All I can say is that Skykilo upped the ante until the math and physics were too rich for this chemist's blood. I fold.

You're quite right, old chap. I wonder what sound and ice tool makes as it penetrates methane and ammonia ice, assuming you had air to conduct the sound waves. Would it give the same satisfying *thunk!*?

The cat got her by the face, so even a helmet isn't going to protect you. Dave, better paint a face on the back of your helmet, as they do in India.

It's pretty hard to make a topo when the comet is remaking it's surface as it orbits the sun. It's got to be the "ultimate chosspile". That must be what makes it so compelling for Dru. It reminds him of his favorite peaks.

"My face reddened with rage. 'No LASERS!? What kind of a robot probe doesn't have lasers? What are you guys doing on this planet, anyways?' "

We're going to need to build some Hoovervilles in which to put all the jobless people who have lost their homes. "The economy has lost about 2.3 million jobs since he took office, giving him the worst job creation record of any president since Herbert Hoover."

Mr. Radon, all the rule said was that you had to store the tailings somewhere other than in the creeks and waterways. You had to put it back on the hill when you were finished getting the coal out. Moving the earth around costs more money. They wanted to just push the mountain tops into the valleys and just leave it there. No way.

He looks pretty good. I'm optimistic that he will only lose just the tips of his fingers.

There was a really long thread about Rocky Butte awhile back. I'll be damned if I can find it. It talked about the needles and the chopped top rope anchors, etc. , ad nauseum.

We can measure the energy of a photon, which is just hv. And we know that m=E/c^2. Thus the "mass" of a photon is equivalent to hv/c^2, but it is rather meaningless, isn't it?

It's not yet clear whether protons decay, but if they do, it's at such a slow rate that you won't need to worry about it, Dru.

How's your Japanese? That is truly weird.

The force on an orbiting body acts as right angles to its motion, hence there is no change in its momentum (mv).

I had to google to figure out who you were talking about.

The one who is accelerating is the one which for which time passes more slowly relative to the stationary one. Wirlwind is accelerating because he has some sort of fusion drive under his butt. Ducknut does not. Thus Ducknut ages faster than wrlwind. wirlwind DOES NOT MOVE. It is Ducknut that moves away from wirlwind. The two cases are equivalent, and thus the PARADOX. There is no paradox. Motion is irrelavant. Acceleration is all that matters. Wrlwind knows he is accelerating because he can feel it. Likewise Ducknut knows he is not accelerating.

Your statement is only correct then the mass of the central object is very large relative to the orbiting body, which in the case of the sun is true.

Suppose wrlwind gets in a spaceship and heads out on an extended voyage (and climbs the walls) while ducknut stays behind on earth and climbs on rock. Wrlwind accelerates at at 1 G, because he's used to earth's gravity. As his ship approaches 0.98 times the speed of light, Ducknut notices that wrlwinds rate of acceleration seems to be slowing. Meanwhile wrlwind still feels that he is accelerating at 1 G. From Ducknut's frame of reference, the mass of wrlwind's ship in increasing and his clocks are speeding up, but as far as wirlwind is concerned his weight, or mass, is the same and his clocks, as well as his perception of the passage of time are the same. So if wrlwind goes fast enough, say above 0.99x C and travels for long enough, he might eventually come home to find himself much older than ducknut, even though they may have been the same age when he left.
