The first question is for Kyle D. Jackson and Jeff Jardine and it is if we (...) (23 years ago, 2-Jul-01, to lugnet.space, lugnet.off-topic.geek)

I understand now in my mind that atoms are what makes the structure of all living organisms and the structure of all living organisms depends on the density and class of materials in the constructuion of space craft. It is obbvious to me that (...) (23 years ago, 2-Jul-01, to lugnet.space, lugnet.off-topic.geek)

| (...) I never spotted this before, but it's further proof that there's negligible friction in space. If there was, the Moon would have slowed down in it's orbit and fallen to Earth, and the Earth would slow down and fall into the sun. Actually, I (...)

| (...) I didn't necessarily mean in space. I was just talking about liquids in general (on Earth, in an atmosphere). Clearly if you're trying to push your way through something, a gas is easier than a liquid, which is easier than a solid. But, this (...)

The whole governing equation of aerodynamics, the famous Navier-Stokes equation, is just a different representation of our well known F=ma. By the way, is it a miracle (...)

Now *that* would look cool, if it was the first time you'd looked up in a few days. Plus, the apparent gravity on the earth's surface (...)

What material would serve the best purpose for cooling off directly in space and would this material work in space to prevent the plasma that powers my space craft from overheating and making my space craft explode into a million pieces?

You said in the last letter before this letter that some liquids (referring to the reaction to friction of certain particles in outer space) are viscious while some solids are very hard and smooth in reaction to friction in outer space. If (...) (23 years ago, 29-Jun-01, to lugnet.space, lugnet.off-topic.geek)

However, liquids, if you boil them, changes materials from liquids to gases, just to let you know, George. :.) (...) (23 years ago, 29-Jun-01, to lugnet.space, lugnet.off-topic.geek)

| (...) Well, it's more about the angle the wing is inclined to the airflow. Just keep it tilted upward to the air flowing past you, keep your speed up, and you should get some lift. Newton says you're deflecting air downwards. Aerodynamics says a lot (...) (23 years ago, 29-Jun-01, to lugnet.space, lugnet.off-topic.geek)

Different materials have different thermal emissivities, so picking one with a high value would be better for cooling directly to space. Of course these materials may be impossible (...)
