Linear Algebra: "Find the Singular value decomposition, pseudo inverse, Cond(A), A^tA, magnitudes, orthogonality, and least squares coefficient fit for the following twenty matrices."

 

Me: "Haaaahhhh no. Yo, Matlab."

 

Matlab: "Sup."

 

Me: "Smoke these fools."

 

Matlab: "A'ight."

This is on the fizziks side of things, but like all theoretical physics it also runs well into mathematics, and so I am posting it here as a nice illustration of how blurred the line between math and physics is:

 

I like Sean Carroll, too bad he got kicked out of U Chicago for not publishing enough. When I mentioned him to my supervisor at the University of Toronto, the first thing he said was "Oh, isn't he the guy who failed to make tenure at Caltech?" :S

I'm taking a Process Controls course currently. We're spending some time doing Laplace transforms to solve ODEs.

Currently using this to solve isothermal continuously mixed reactor problems.

God I hate diff eq.

Welcome to the Club of Diff. Eq. Haters, you are but one of many.

Wait until partial differential equations

Already dealt with some when analyzing 2 and 3 D heat flow. You don't solve analytically. There are some great chemical engineering programs to solve them numerically. 

PDE's are hard for me to imagine though.
