I have been wondering why is potential energy not included in the calculation of total energy E=m[tex]c^2[tex]? I know that m[tex]c^2[tex] includes the rest energy and the kinetic energy. Suppose the particle or object is charged and is moving in a strong electric field, its potential energy...

To Futz: Thanks for your reply. So what you are saying is that the "physical" wavelength is also the wavelength of the wave function, whose modulus calculated at a location represents the probability of finding the electron at that position? Can we apply this to photons and say that...

I was told that for an electron, the wave length lamda calculated from De Broglie's equation ( = h/p ) refers to the wave length of its probability function (as solution to Schroedinger's wave equation ), and is not its physical wave length as exhibited in the electron's double slit diffraction...

How does a Fluorescent Light Work I thing the question is: Without a starter and having only a capacitor, how is the lamp "fired up"?

My fluorescent light stops working but I could fire it up by plugging or unplugging a cellular handphone charger form a neighboring socket! This means the tube is still ok as all it needs is some high p.d. across it - in this case provided by thehigh electromagnetically induced emf caused by...

neutrons Thanks for the fast response! What I really want to find out is: In their natural occurring way, why don't neutrons seek out one another and form stable clumps? Bear in mind that 2 neutrons and two protons do just that and form a very stable helium nuclide, although there is quite...

We all know that the helium nucleus is very stable because it consists of two protons and two neutrons. My question is why aren't we seeing 4 neutrons sticking together forming an even more stable nuclide, since neutrons exert only the strong attractive nuclear force but not the repulsive...
