Happy Monday! It’s thundering and raining up a storm here, so I’m pacing around the bottom floor of my apartment to try to get my steps for the day. Exciting stuff, what can I say.

Speaking of exciting stuff, today I got to practice differential equations! No, that’s not sarcasm, I actually really enjoy solving differential equations. It reminds me of the time I went to summer school in college. I took Diff Eqs so that I could free up some space in my academic year schedule (to take classes not at all required—yep, I have always been a huge nerd). I was still a fresh-faced third class midshipman, excited about not being a plebe anymore (the new class of plebes (Class of 2010, jeez I’m old) were there and calling me “ma’am” when they ran by me, which was…strange, to say the least), and loving getting to spend my time chilling and doing math. I gave up my summer leave to do so and never regretted it.

In any case, reminiscing aside, there’s just something very satisfying about it. Identifying the best way to solve it, doing some algebra, then some calculus, and somehow ending up with a solution. Quite good. Today’s chapter was limited to first-order ordinary differential equations, aka the easy ones.

On the astrophysics side, I continued my journey through stellar astrophysics to learn about protostars, star formation, and pre-main-sequence evolution. This was an interesting topic, and I liked how the book layered on the complexity. Start considering only gravity, then add gas pressure, then add magnetism…now you’re cooking with gas! There’s a whole host of interesting complications to consider, and the text frequently mentioned that it was an active area of research. Which makes me wonder what the status of it is now, 11 years later! I may have to do some digging just to say.

It was a good day for studying here, even if I did lag a little bit and not finish until 10 PM.
