I may be mistaken, but I figured I'd bring it up so that people who know more about it can chime in. Wouldn't engineering technology be a more appropriate major for someone who wanted to go into a more hands-on job?

I downloaded this a couple days ago: https://chrome.google.com/webstore/detail/lfkgmnnajiljnolcgolmmgnecgldgeld. It is amazing - right click mouse gestures. Tons of different gestures, you can disable the built in ones, add new ones, modify the gesture movements, etc. It speeds up browsing...

Thanks for all the information; it was very helpful. Do you know why tuition was raised specifically for STEM students? That seems odd...

I'm assuming you mean z is some function z(w) of another complex number w. So Yes, since f(z) = z = z(w) is just the identity function.

Not that this is a proof, but intuitively the direction of the gradient of a scalar function gives the direction of maximum change of the value of that function. Since your scalar function is the distance from the origin, and it makes sense that the direction of the gradient is in the direction...

Dr. Reinhart Piltner used complex analysis to find a general solution for 3d static elasticity problems in terms of complex functions, which amounted to finding a biharmonic potential function in terms of six arbitrary complex functions of three complex variables (of the form \zeta_{i} = a_{i}x...

Thanks for the reply clope, you sound like the perfect person to ask. I would like to know such as how prevalent undergraduate research/co-ops are, the general level of seriousness/knowledge/etc of the majority of students, the quality of labs/lab equipment - pretty much your general take on...

Hello everyone, I'm considering transferring from UCF (double major in Aerospace Engineering and Electrical Engineering) to FIU (double major in Physics and Electrical Engineering). The transfer would be due to personal reasons, not anything academic-related. The change from AE to physics is...

Haha, this is pretty much what I expected. You definitely have to read between the lines to get a clear picture. I read through all the comments and almost always wind up going with the lowest 'ranked' professors. Along the same lines with what mathwonk said, I usually wind up picking these...

Alright, I think I got it. Along the way I had this: \overline{\Gamma}^{m}_{r s} = \frac{\partial^{2}\vartheta^{n}}{ \partial\overline{\vartheta}^{r}\partial\overline{\vartheta}^{s}} \frac{\partial\overline{\vartheta}^{m} }{\partial\vartheta^{n}} + \Gamma^{n}_{n q}...

Ah awesome, thanks. I never use the Tex because it always did that and I couldn't figure out why. Good to know. Still haven't figured it out by the way, if anybody can explain it. Thanks again

Hey everyone, This formula was just provided in a book and I was trying to prove it but I'm having a hard time understanding what it's saying. The formula is attached, along with the definitions given for the Christoffel symbols. In the definitions the i's are the standard basis vectors and...

Vladimir Arnol'd has a ton of books, I've only got a chance to take a look at 1 but I hear they're all excellent.

Which parts did you find the most confusing? Do you have a harder time applying the techniques or understanding the concepts? What is your major?

Hi everyone, I'm an undergraduate student. A professor just signed me up to do a research project (my first) this semester, and I need to be able to apply elasticity to analytically find stress concentration factors in a specific geometry (I'll pm you if it matters which geometry) that the...
