If you have a system with equally distributed temperature, and in the center of it is inserted a point source of heat (a point hotter than the rest of the system) after a given amo …

I am developing a heat map image generator and I have come to 2 solutions to calculate the intensity in a given point within a distance from the heat source: The first one is simi …

How much energy would be released for 3.5 moles of pentane. How much energy would be released for 10 moles of pentane. How much energy would be released for 0.75 moles of pentane.

I'm not sure the question is meaningful, but still - do electrons inside normal matter sometimes collide with protons to create neutrons (that may have a very short half-life)? I …

If any particle has a probability to be observed anywhere, as QM states, does this mean that it can be observed outside its light cone and violate speed-of-light limit?

hi there..may i know ur contact information like email address or msn? i m interested in this website u build here.

You know, out of all these, which do you believe "is true". (Yes, this is a totally subjective and undefined question, still I think it's an interesting one).

What are characteristics of internal magnetic field variations at earth surface.

Or is it just a random word chosen to describe physical property (like quark/gluon "color" or particle "spin")?
