Comment: Re:It will fall down (Score 1) 480

You're still missing the point. At the same pressure, a litre of hot air does have less mass than a litre of cold air. Hot air rises because it is less dense than cold air, because the particles bounce off each other more energetically. So yes, heating unconfined air does make a given volume lighter. The relationship between the particles average speed (be careful here, you said velocity) and the Earth's escape velocity is such a smaller effect as to be negligible.

+ - Brain grown in jar pilots F-22 sim-> 5

Submitted by NJ Hewitt
NJ Hewitt (1048942) writes ""Florida scientists have grown a brain in a petri dish and taught it to pilot an F-22 jet simulator." The brain, with neurons connected to 60 electrodes, at first had no ability to pilot the fighter jet, but slowly learned and can now reliably navigate through even hurricane-force winds in the simulator."
