Maybe There Are Two of Me and the Clever One is Hiding?

I'm in the midst of reading a book about the representation theory of Lie Groups. I have to think hard and take a lot of notes and trace through a lot of details in order to understand things. Slow going.

Today when cleaning out my filing cabinet, I found a graded exam from when I was in graduate school.

It was in my handwriting.

It had received an A.

The topic was Lie Groups.

I don't even remember taking a course on Lie Groups. (A transcript wouldn't help: most of the courses I took had generic names like "Special Topics in Mathematics.")

I also believe that there was a time about 15 years ago when I knew something about physics.
