As a professor in the math department at Cal Poly, one of my primary jobs is teaching mathematics. Most quarters, that means teaching two sections of calculus and one higher-level course. It also means working with students outside of the classroom, generally in the form of senior projects and independent studies.

## Courses I Teach

Fall 2017

## Math 244: Linear Analysis I

“A differential equation is a mathematical equation that relates some function with its derivatives. In applications, the functions usually represent physical quantities, the derivatives represent their rates of change, and the equation defines a relationship between the two. Because such relations are extremely common, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology.” – Wikipedia

“The results of mathematics are seldom directly applied; it is the definitions that are really useful. Once you learn the concept of a differential equation, you see differential equations all over, no matter what you do. This you cannot see unless you take a course in abstract differential equations. What applies is the cultural background you get from a course in differential equations, not the specific theorems. If you want to learn French, you have to live the life of France, not just memorize thousands of words. If you want to apply mathematics, you have to live the life of differential equations. When you live this life, you can then go back to molecular biology with a new set of eyes that will see things you could not otherwise see.”

## Math 344: Linear Analysis II

“The Laplace transform is an integral transform named after its discoverer Pierre-Simon Laplace. It takes a function of a real variable *t *(often time) to a function of a complex variable *s* (frequency). The Laplace transform is very similar to the Fourier transform. While the Fourier transform of a function is a complex function of a *real* variable (frequency), the Laplace transform of a function is a complex function of a *complex variable*.” – Wikipedia

“Ce que nous connaissons est peu de chose, ce que nous ignorons est immense. [What we know is not much. What we do not know is immense.]”

### “Algebraic geometry seems to have acquired the reputation of being esoteric, exclusive, and very abstract, with adherents who are secretly plotting to take over all the rest of mathematics. In one respect this last point is accurate.”

### “We now come to two (sets of) facts I wish I had learned as a child, as they would have saved me lots of grief. They encapsulate what is best and worst of abstract nonsense.”
