If you're interested in personal help, I've posted my tutoring services on Fiverr: https://www.fiverr.com/s/dDYkBlz

I have not had the opportunity to teach mathematics as much lately, given the amount of focus I have given to my research. I enjoy the process of teaching and interacting with students and so have decided to do some online tutoring.

Part 5:    • Is Euler's Number a Geometric Number?...  

Given any conversation between two mathematicians in which π is discussed, sooner or later, Euler’s number e comes up. In this video, we want to address the question of whether Euler’s number admits a geometric interpretation. That is, in the sense that π is geometric, is Euler’s number geometric?

8:55 Are these geometric characterisations?


This is part 1 of a short series of videos in which we address what makes a number geometric, and whether Euler's number is such a geometric number. The answer turns out to be surprisingly non-trivial, and such an elementary question turns out to be an active area of mathematical research.

Hi, my name is Kyle and I'm currently doing my doctoral mathematics degree in complex differential geometry under the supervision of Professor Gang Tian and Professor Ben Andrews.
