I am currently an undergrad at TUM and am planning to stay in the academia in the future. My goal is to become a theorist, however I cannot choose a grad school to apply to. I understand that "best" is subjective; my most important criterium is that the degree would allow time to actually learn stuff instead of speedrunning through everything just to get the deadlines. I was initially thinking about the Mathematical and Theoretical Physics MSc at Oxford, however I met someone who has studied there and is now doing a second masters at TUM since he felt like the first one was too rushed. So far the theorists I've met from Russia have been very impressive, which's why I also considered Moscow Institute of Physics and Technology, but I am not sure how the current Russian politics is affecting that. So does anyone have any opinions on which universities offer an appropriate grad program aligning with my goals?
