Faint praise, but ambitious of you, nonetheless.
I then went on to take (learn and enjoy) linear algebra and population dynamics which is ENTIRELY math based.
Reminds me of a story. There is a mathematician chatting with a physicist at a party. He asked the physicist what was the work for which he won his Nobel Prize. The physicist goes into a long-winded explanation of the details of his theory. The mathematician ponders for a brief moment and responds, "So you inverted a matrix."
Probably a true story. Gallian's Abstract Algebra book describes how physicists made a breakthrough when they discovered that matrices don't commute. Go figure.
I then went on to earn a MS in Population modeling, which, as I'm sure you know, is a biological discipline based entirely one two things: EVOLUTION and MATH.
Population dynamics,... I'm not familiar with the term, but I'm sure it uses some very sophisticated stochastic differential equations. So, in your classes, do you prove the theorems of Ito calculus from measure theory directly, or do you just take Brownian motion as a given?
