Computational Definition and 321 Threads

I have received some admissions decisions from the graduate programs that I have applied to, and I am stuck with a tough decision to make. I am hoping to hear from those who may have found themselves in a similar situation or someone who may have relevant industry experience who can shed some...

This is for a computational physics class, but isn't a homework question, per se. My friend and I have two different sets of code trying to achieve the same thing and we're getting vastly different answers, orders of magnitude apart. We haven't covered this sort of problem in our intro E&M...

I've decided to learn Python (having a background in C++ and Matlab), and I'm a little unsure about which version to get. I've read in a few places that Python 2.x is better because packages like numpy and scipy don't work with Python 3.x, but this seems to be out of date since as far as I can...

So I'm an undergraduate student in Chemistry in my junior year and I recently transferred schools for a better science program. The one I was at was very, well, easy. Like toddler easy. I never went to class and I aced everything. Here, they're far ahead and it's much more rigorous. I was...
