Im not talking about TVs, but radio astronomy. We receive signals from say a distant star and turn it into a picture, but how?

Ok, I'm out for the summer, but we never covered all the quantum dynamics chapters. I am interested, but am having a bit of a hard time in self study i.e. understanding the Schrödinger equation. Any recommendations? Any books?

There was a physics problem about light propulsion in my physics book. If an astronaut weighing 100 kg fired a 1 kw laser away from him, how long would it take him to move 20 meters? I don't recall the answer exactly, but it was around 10 hours. If instead he threw a show lace, he would get...

So it is all based experimental data? So I guess my pursuits of reasoning why light is constant in all frames is constant was a fruitless endeavor this afternoon. I am relieved, I thought I was missing something. "The Elegant Universe" by Briane Green has a few good chapters on relativity...

I'm missing something here. To my understanding, regarding the classic light clock example. When it is stationary the photons go vertically up and down. However, from our perspective when the light clocks are moving at some immense velocity, it appears the photons are moving diagonally. Since...

I understand why it needs to be for relativity, but I don't understand why it is always c regardless if we're speeding toward it or away from it as some insane velocity, can someone tell me without a reference to relativity?

Linkage or more examples?

Anyone know any applications on planetary motion or systems of attracting bodies?

blech! thermo!

Any thoughts besides dual spring or electrical systems?

Yes, that is what frightens me. Any uplifting comments though?

Take a look, http://lorenb.com/software/sproing/ I can't imagine the differential equations needed for this to work...

I seem to have grand, romanticized notions of what a physicist does during the day. If you are a physicist, I would like to hear from you. What do you do day in and out? Do you enjoy your work? What level of education do you have for your physics job?

I am wondering about this, too. Take the kinematics formula ?D=volt+.5AT^2 and I want to have take relativistic affects in place, would I need to do anything more than just subsitute the time dilation formula into the T variable?
