We spend the last several weeks in my Real Analysis course on Fourier Series, which I had never seen in undergraduate. So I spent a fair amount of time in an undergraduate text book trying to learn how to do it. But that is neither here nor there, because the rest of the class understood most of it, so our professor felt comfortable making a couple extra comments about the work we are doing. I have collected four quotes from one class- all of which my professor spoke in a dead pan voice which he used to give the rest of his lecture.
“If you consider Fourier Analysis useful, then these theorems are useful.”
Because who wouldn’t find Fourier analysis useful?!
“Real Analysis: Calculus in a form a calculus student can’t recognize”
We were taking the Fourier transform and as you may know pi appears at fairly regular intervals. And as it appears we hear,
“It always amazes me when these things happen, Where did pi come from?”
Our professor pauses to look around the classroom, as though he might see the pi symbol zoom into the room through one of the open windows (!), then continues with his lecture.
And finally, one of my favorite quotes from that class for the whole year, after finishing a proof with a flourish he pontificates,
“All of mathematics is related!” “…except maybe combinatorics.”
So there you have it, if you are a combinatorics lover, then you are not related to anyone. Have a lovely week!
