Are there mathematics seminars to attend in the summer, or do they typically only occur during the academic year? I am referring to American universities.
An idea I had last night was to YouTube some math seminars to see what talks I can watch quickly - talks are about an hour long. I found a good PDEs talk from a Princeton seminar. I hope to find more talks that are available online.
Is this not advisable? These are talks given by experts, and as a lowly master's student, I naturally do not understand about 90% of the mathematics being talked about and written on the chalkboard. I am mainly just trying to get some sense of purpose of, say, studying PDEs, its difficulties, etc.
I am also making progress on a master's thesis, but my gut feeling is that this problem is too narrowly focused and in the end may not help me figure out better my research interests in a PhD program.
What else could I do?
