" Namely, the scientists suspected that heat was being emitted by the spacecraft 's generators anisotropically — more in one direction than the other." The heat is not emitted at the same rate in every direction, that's exactly what's causing the acceleration.

O, yes I've read about this in "the trouble with physics" by Lee Smolins, as a possible proof that relativity is not as universal as we thought. But it seems it'S simpler than that

Without any experiments I would say that the car will move at 55+60=115MPH, relative to the ground, and at 5MPH relative to the truck. Is that right?

I think I understand gas leaks, but why does the heat emission cause it to slow down?

Hi As a school project, I want to construct a Stirling engine (particularly this kind : http://monsterguide.net/how-to-build-a-stirling-engine ). The execution is quite simple, but I do not fully understand the theoretical background. Can someone give me an explanation?

For further information on social evolution, and strategies, I'd recommend Susan Blackmore : The meme machine. I very much enjoyed it after the Selfish Gene
