Today I did a very difficult thing: I threw away my University Lecture notes.
It was all part of the Great Junk Room Clear-out. I had folders in there which I hadn’t looked at since the jubilant day of my final exam, five and a half years ago.
After I’d had stern words with myself, I conceded that I was unlikely to need them again: my career has led me down a path in which the finer points of Representation Theory are no longer of practical use. Besides this, my handwriting could justly be described as write-only; scrawling the notes helped the content stick in my memory during the exams, but it certainly doesn’t serve for archive purposes.
I must confess to flicking through the pages nostalgically before consigning them to the recycling bag. I have fond memories of the days when I understood those Theorems, Lemmas and Corollaries.
