I know reason is thought in a philosophy course, and scientists are very good at reasoning, so does that mean all scientists took a course philosophy to learn how to think critically and reasonably? If not, then how does a student of biology learn how to think outside of his field of study...

If you then remove God, humans suddenly lose their rights? I know Thomas Paine wasn't the most religious man of his time.

At least I think the question goes here... I was reading about Thomas Paine, and something caught my eye... What did Thomas Paine mean, by Natural rights? What are these rights? http://en.wikipedia.org/wiki/Rights_of_Man"

I really want to learn this stuff, can anyone give me good places to go to to read this stuff? I would really appreciate that, thanks. :)

So, the photon isn't made out of perpendicular magnetic and electric fields? And the electromagnetic field isn't made out of photons? So what is the magnetic field made out of? I know I'm asking a What is? question which aren't really answered in science, like What is space?, but the magnetic...

http://en.wikipedia.org/wiki/Magnetic_field#Quantum_electrodynamics" Ok, I have just become even more confused. What is the magnetic field then?

I apologize if I wasn't clear, my question was concerning the quantized view of the magnetic field in Quantum Electrodynamics. In QED, as I have come to understand, the magnetic field is nothing more than a "photon field" of sorts. But photons themselves are made out of magnetic fields. I...

So then what is a EM field?

QED states that the magnetic field is a kind of "photon lattice" and the force we feel when a magnet pulls of something is the exchange of these virtual photons. But I become confused right about here, if the magnetic field is virtual photons, which are themselves wave packets of magnetic and...

What if you could build a rocket, with the exhaust "leaving" the engine at a instantaneous speed, would such a rocket with a infinite exhaust move? The particles leaving the engine will reach a different destination as soon as the rocket was switched on, so how could such a rocket exert a...

This is a question which I can't seem to find a answer to. How does a magnetic field physically attract another magnetic field? I mean does Quantum Electrodynamics explain magnetic fields as well as the EM force? Or is it some kind of different quantum field theory?

I don't really understand quantum physics, but I would really like to know because I'm going to study it next year. Can someone explain it to me in laymens terms, thanks.

So has Gravity Probe B detected Frame Draging?

I was wondering, if you where going at 0.16c how fast would it take you to get 4 light years?

I am doing report and I need to know how fast it will take you to get to the nearest star at .5c? Thanks.
