Undergrad Difficult Problems in Classical Mechanics
My professor for classical mechanics has asked that we find some difficult problems in classical and solve them. My first thought was to look through my book for hard problems. However, we are using a free PDF that is rather lackluster when it comes to homework problems. Almost all of the...- SpaceWalrus

Schools Community College or a Not so good CSU
I think the answer will depend on the CC you intend to go to. I currently go to a CSU, and we receive many transfer students from the community colleges near by. My school isn't particularly difficult. However, many transfers struggle with switch from the CC lifestyle (sign up for 9 classes...- SpaceWalrus

Need help on getting letters of recommendations for REU
If you have only been at that school a semester, it might be difficult to get a good letter from anyone. Regardless, here is what I suggest: If you want to ask your professors at your school for letters, just e-mail or ask in person, the (two?) that you know most. Its best that you select...- SpaceWalrus

Math Become a Research Mathematician: Advice and Tips
Thanks for the reply. Like I said, this would be my backup plan for life (at least temporarily) if I don't get into graduate school. Consequently I haven't put to much thought into it, and I honestly don't know where to begin. The only route I know how to navigate is one that continues down...- SpaceWalrus

Math Become a Research Mathematician: Advice and Tips
I am applying to graduate schools right now for mathematics. I have been a part of four different research projects during my undergraduate career. These have been the most fun and rewarding part of my undergraduate career. If I do not get into graduate school, I will be looking to...- SpaceWalrus

Graduate How Do We Classify Higher-Order PDEs with Multiple Independent Variables?
Either really... Second order with n variables, or n order with 2 variables (or n order with m variables).- SpaceWalrus

Graduate How Do We Classify Higher-Order PDEs with Multiple Independent Variables?
This surprises me. Is this because forming a general classification system its more complicated than I imagine, or just that doing so serves little to no purpose?- SpaceWalrus

Graduate How Do We Classify Higher-Order PDEs with Multiple Independent Variables?
Suppose you have a PDE with an arbitrary number of independent variables (not necessarily two), and of order n. Is there a nice classification akin to the hyperbolic, parabolic, etc. Thanks- SpaceWalrus

Testing Math GRE Practice Exams: Is this all there is?
Don't know what you mean by this. You are asked to prove things all over the place (e.g., find the cardinality of a set, find the limit of a sequence, etc.) Regardless, I can attest from experience that the practice exams are far easier then the real exam... I took the most recent one, and I...- SpaceWalrus

What's the competition like at (Math) REUs?
To be honest, if you don't get into an REU its not because you weren't qualified, its because you were probably over qualified. Having gone to a "top math university", and taken 9 graduate courses is a turn off for many REUs. The point of REUs is (or was) to expose students to research and new...- SpaceWalrus
