hitssquad: Alt-Tab has nothing to do with tabbed browsing. Tabbed browsing refers to the fact that you can have multiple pages all within the same browser window. On the bottom (or top) of the browser window you have a little tab-bar like the taskbar, with each tab representing one page. The...

To avoid your PC from shutting down: When you see the window that tells you the PC will shut down in 60 seconds, click on Start. Then select "Run". In the new window that appears type this text: shutdown -a You have now prevented the shutdown (once) and have enough time to download a...

Why? Photons have no mass. They also have no "size" in any real sense. So most of the relativity stuff just doesn't apply, like the lorentzian contractions for instance.

Well, at some point you have virtual photons, gluons and all the other stuff interacting between the molecules, the individual atoms, within those atoms... But they aren't really of importance if you are just interested in the propagation of the shock wave. If you want to calculate the...

But the force of attraction between two objects is very much dependant on their mass.

Agreed. To follow up on your argument, you could replace c with /epsilon and [tex]/mu[{tex], et voila: you have those two popping up in every other equation. "The energy of light" sounds almost philosophical.

That would be something like to compton scattering, wouldn't it?

That is kinetic energy, not potential energy.

I know you asked for mechanics books, but soon enough you'll need books on electrodynamics, and then you should seriously consider getting Jackson - Electrodynamics.

Is there a free service, or do you have to pay for all of them now.

Just grab a general physics book used in universities for the first or second semester classes, and read through the thermodynamics chapters, and maybe the associates ones (gases and fluids). If you want to know more, you can get a book on theoretical thermodynamics or possibly statistical...

Well, ok, but that wouldn't make it supersonic, would it?

Hmm... you could take the total mass of the ejected gases, and assuming they are ejected at a constant velocity (which they should be, more or less) you can easily calculate the total momentum of the rocket. That should be a lot easier, although this might be incorrect as well.

Well, with radio waves you can basically do a lot, the problem is that it requires more than the simple things described in this thread to broadcast a song, for instance. I don't see a whole lot you can do besides maybe creating and detecting them, although even that has a lot of applications...

So no .h? Well, now that the strings are working it is much easier. Thank you.
