On Tuesday, topology suddenly got hard, and I realized I didn’t understand anything. After a bit of studying, I was able to understand most of yesterday’s lecture. I still have to learn what quotient spaces are. Hopefully I won’t have as much trouble with quotient spaces as I had with quotient groups. Ring theory is getting interesting.
I can’t log onto my Arrowhead water account. I need to start getting much more water desperately since I feel dehydrated almost all the time. It doesn’t help that the classrooms don’t have any ventilation.
I went to Rabbi Steve Cohen’s “State of the Union” speech yesterday. Unlike two politicians who are actively destroying the state and country in which I reside, the Rabbi has evidently made UCSB Hillel into a much better place. Apparently crowds of 200 were completely unheard of a few years ago, and now such crowds are normal.
One of the students in the AoPS MathCounts/AMC Counting class was kind enough to tell me of a very nice free LaTeX system that can generate PDF files. That is good news since PCTeX and Acrobat Distiller together don’t make proper PDFs. That will make my life much easier.
