How do I make a attitude trajectory of a satellite so the attitude always points towards a point on earth given its current orbital position?
Let us say there is an antenna on earth and I have a satellite in an orbit how do I make the trajectory (not control, so body velocities of the satellite) to make it point toward the earth when it is ...

Does the weight of a pilot exponentially affect the necessary weight of human-powered aircraft?
The MIT Daedalus, a human-powered craft, weighed about 31 kg. This was significantly lighter than its pilot during its record setting trip, though I can't confirm the pilot's exact weight. Still, this ...

(Why) does the sound of propeller planes change with increasing distance?
I recently heard a propeller plane, and then very shortly after a jet like noise. After I did some probability calculations, I conjectured that probably these two events are timely correlated.
I also ...
