Currently grading the exams of our grand tour of math lecture (combinatorics, complex number, linear algebra, Transforms, ODEs and PDEs).
Very happy to see that the students did exceptionally well!
Damn skippy, someone even solved the i^i spicy question.

I am currently reading Innumeracy.
We were warned about the dangers of a society incapable of doing basic math 37 years ago.
How I wish elected officials, anti-vaxxers and conspiracy theorists would read that book😞.
