Reading 2.10

Linearization in sight! Mathematicians delight! Wow, there are way to many syllables to sing that accurately.

To sum up, the acoustic approximation rocks. It makes it so that convection drops out and so that the continuity equation is decoupled from the field equation. Pretty neat. I'd like to explore, eventually, real life situations where this approximation breaks down, but I'm pretty sure that we have only seen the tip of iceberg when it comes to the plethora of real life things that do fall into this approximation.

Reading 1.1-1.5

It's after midnight, but I'm going to let it all hang out. What's the reference? Anyone?

Well in all seriousness, this reading has served, for me, as a great quick refresher and an introduction to some new physical intuitions / terminologies. However, I'm more excited about using tensors again and getting our hands dirty. Or at least watching hands get dirty in class.

Speaking of which, I really appreciate anyone and everyone who is reading my posts. Since this class is an experiment for me, thus far, in determination in attending and participating in a course that I'm not enrolled in, I may be making more light of things than I should. I hope that I can stay in line (relatively), and I'll see you in class.
