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...

A while back I tended a course in transform methods. During the course we were handed a MAtlab program that could be used to simulate convotution called Discrete Convolution Demo. It's kind of big or you might say bloated and I'd like some lightweight version or something. If someone know some...

Last night I tried answering a question I've had for a while- can you really do a proper FEA analysis using free (or at least very cheap) software? I've found myself recommending a couple of times to find a free FEA package for running an analysis on simple geometries, but I don't actually have...

Perhaps someone may be able to suggest (Windows) software that I could use that allows me to draw experimental set-up schemes on my computer (i.e. include images such as beam splitters, wave plates, PBS’s) without much hassle? Anything that is open-source, perhaps? And easy to use? Otherwise...
