So I have an appointment with the liver specialist next week and they need to take blood out of me now. Three months ago, my liver enzymes were normal, and if they're normal again, we'll just call it good and forget the whole thing. If they aren't, the liver specialist will devise cruel and arcane tortures for me.

For whatever reason, I've sort of been thinking about real math again. I feel like at least reviewing some stuff. I realized, to my shame, I barely recall anything of Galois theory and could not prove Abel's impossibility theorem anymore. I mean, I recall the method: A5 is not solvable. But not the details ("And here we say something about Galois theory..."). As a reasonable person, I would also prefer to be able to prove the fundamental theorem of algebra using Galois theory in order to use at least a little bit of algebra in it. So I should review some stuff. Just enough not to be embarrassed. Ditto for real analysis, and then functional analysis, as well as topology and algebraic topology. To what end? I don't know, just not being completely useless. This goes hand-in-hand with my current work on the more statistical, applied end of things. Well, not really. My real project right now on top of my coursework is learning some basic programming and, oh yeah, getting a new jorb hopefully. But light review of real math and heavier review of discrete math should be helpful to me. What I might do is find some cheap Dover math books. I don't have much free money these days. By the way, if you're looking for a good Dover math book, Kolmogorov and Fomin is great.

Anyway, it seems our roommate broke up with her boyfriend yesterday. Good for her. Wouldn't have worked in the long haul.

The wifing unit is ripping through the Doctor Who stuff. She's been insomniacal lately. One thing I don't like about the new series is the romantic capabilities of the Doctor. The closest thing we can have to "romance" is Tom Baker flirting with Lalla Ward, and that only because she's a Time Lady and the actress was going to marry the actor in real life.

The SVP of Big Stuff told the SVP of My Area that this thing I made and my boss presented the other day was awesome. I'll say I should get more moneys.

Still sick.

Still not recovered from that terrible chess game.

I get pretty bored with any proof by the mariner (2.00 / 0) #1 Thu Oct 13, 2011 at 03:51:46 PM EST
Of the fundamental theorem of algebra that doesn't involve winding numbers.  

What I found really fun for getting a feel for programming python was ipython + either numpy or networkx and matplotlib. Just screw around with little mathy things with the ipython console and a text editor. Code up numerical crap, play with graphs, whatever. You get a lot of canned math and plotting/drawing stuff and a programming language to do whatever you like with it. With the online help/tab completion, you get a feel for libraries much more quickly. Of course, you can do similar things with matlab, but I find its online help and programming language in general pretty clunky. 

I keep thinking this "Design Patterns" book sounds like it's worth reading.
