What is Preparation: Definition and 198 Discussions

I have been reading this explanation about superpositions and mixtures. The author takes the example of two non-overlapping regions in space, each covered by a gaussian wavefunction. He goes on to compare the superposition and the mixture made up of those two gaussian functions, based on their...

I'm looking for a book to self-study this summer before my last course of Bachillerato (A Levels or High School in other countries). My performance in Mathematics has only improved and I've just been given the maximum mark this last term (10/10 or A+). This has motivated me a lot to keep...

Hello all: I just finished my last semester at a community college, and I'll be starting at a university in the fall. I'm a little concerned with my preparation, especially in mathematics. My major choices were nuclear engineering and physics on my application, so I could be majoring in either...

I chose physics knowing that I probably will not go to graduate school for pure physics. I'm interested in interdisciplinary research whether that is in EE, biophysics, or Earth science, etc I do not yet know (though I'm leaning geophysics). I switched from engineering to physics because I like...

Whenever people ask what jobs they can do with a B.S. in physics (and to a lesser extent with an M.S. or Ph.D.), one of the first suggestions offered is that they can become a programmer. In my opinion, this is seriously wrong and harmful advice. Look at the standard courses that physics...
