comment What is the most counter-intuitive result in physics?
If you want it CW, you have to flag it for moederator attention. Anyway, even as a CW question I don't really this is a real question... What's the point listing results in various fields of physics that one consider "counter-intuitive" ?

comment How should a physics student study mathematics?
@Mark: "... my conclusion that physics student need a deeper mathematical grounding than they typically receive." Again, I think this is just your opinion ... of course the more your know in mathematics the best, but I tend to perceive this as an basic criticism about any physics curriculum ...

Now it should be clear and correct (I hope).

Why do you restrict it to quantum problems ?

comment Software for physics calculations
Not to mention that your institution can probably provide you shared licences (licence server) of Mathematica or Matlab.

comment Velocity of Object from electromagnetic field
OK, I took the shortcut "acceleration = change in the magnitude of the speed", but you're right.

Just perfect and fast answer, I don't think anything should be added.

@Mark: Maybe I am not reacting appropriately because I do not understand your English ... Let's wait for some answers.

comment How should a physics student study mathematics?
@Mark C: the main problem I have with this question is that you are writing constantly things like "This question is broad, involved", "Please do not rush your answer ", "insulting", "promise" ... just ask your question and let people answer if they understand what you want.

I didn't voted to close, but I don't understand where you are trying to go with your question. Maybe that's because I am not native in English although on SE I usually understand the questions.

comment How should a physics student study mathematics?
"the typical curriculum required for physics students is not deep or thorough enough; mathematics is more general (that means work!); and it only requires a few more classes. " this seems a bit contradictory to me...

Note that the principle of virtual work is called D'Alembert principle: en.wikipedia.org/wiki/D%27Alembert%27s_principle

OK, I agree, as I said, this is a simple model.

comment How's the energy of particle collisions calculated?
OK. You have E = gamma m0 c2 so if you have the speed you have gamma and the energy. So yes, the energy will be higher. Note that in all these cases, when work with these concepts it is very rare to think in term of speed; it is easier to talk (and measure) energies and momenta.

comment A force's magnitude
You already know the answer ...; I was saying that a force is just a normal vector, call it magnitude, strength, length, norm, size, whatever you like. The magnitude (strength) is not different from "vector" as Herb said. A vector has a direction and a magnitude (strength).

comment What new breakthrough energy technologies are close to being realized?
I don't think anyone ever talked about anti-matter annihilation except Dan Brown. + this is not a real question as no one can answer it. I would vote to close.
