I know you mentioned adjusting to the pace of Hubski vs. Reddit in your "meet Hubski" recording, and I apologize for how long it often takes me to respond to things. Life seems to be moving at a breakneck pace all of the time, it's difficult to find enough time in the days. Also, I partied so hard last night. Like... woke-up-and-sleepwalked-out-of-my-friends-apartment-hard. It's OK though, they went after me before I could do anything bad. Turns out I was just lookin' for the bathroom. Absolutely not. I need the practice of explaining my trade to folks of all different scientific levels. Start programming. Learn Fortran and Python, and start checking out numerical methods. A good text for that is Numerical Methods For Physics by Alejandro L. Garcia, which is on Amazon for cheap. For familiarizing yourself with space science (a bit broader, but includes geophysics), a good text is Introduction to Space Science (lol) by Kivelson & Russel. Also, learn how to work a screwdriver so the experimentalists don't laugh at you. The university systems will have you so specialized and math-centric that it's not going to be easy, but try to develop a skill set as broad as possible. And don't forget to have fun, dude. If your idea of fun is Fourier transforming a six-dimensional phase space, I'm jealous.Mind if I will badger you with questions after my internship will end?
Mind sharing some starting tips for a theorist in the making who likes to get his hands dirty?
