The flames are all long gone

Handed in the assignment at 9 am, and shortly afterwards was annoyed to note that I'd written "determinant" where I meant "discriminant". After correcting a small error in my use of the chain rule I thought I'd done all the fixing necessary, but I didn't really bother re-reading my actual words.

Then there was a lecture. It was on separation of variables, the technique which we didn't get to yesterday. And assignment 7 came back; I got 18.5/20, equal to my record high mark for assignment 1, and the second time in this course that my mark has increased from one week to the next. [I've worked out what's wrong with this DE part of the course: there aren't enough theorems to prove.]

Then it was the end of week 10. Only two weeks to go now. I'm impatient and sad at the same time.
