## I am a double agent (kind of)

Subtitle: I have so many things I want to do with my life and there’s no time to do any of them in time because I’m leaving for college in less than a month.

Why the title? I’ve been looking for a good proofwriting course that is pretty easy to get into so that I could have an easier time learning some higher-level math courses if the time comes. That search is finally over thanks to many of my friends that decided to go to Caltech instead of MIT (I will miss them so much and it makes me a little sad every time I think about it). Caltech’s curriculum is theoretical from the start, and it shows since they have an into math class that freshmen can take over the summer called Math 0.

The full class apparently comes equipped with video lectures and the ability to send assignments to graders that give super helpful, detailed replies and annotations. But I was only able to get my hands on the PDF notes and problems, which honestly is more than enough seeing as I’m having a lot of fun figuring out the problems on my own and I’m halfway done. If anyone’s interested in the PDFs, Caltech or some administration would probably shoot me, so just give me a private message or email me (found in my About page).

So another thing that I’ve really put off but I really want to do is review 18.02, something I touched on last blog post. Denis Auroux is honestly such a wonderful human being and I love listening to his lectures and his amazing accent and his perfect handwriting and speed-erasing. I’m really sad he’s not at MIT anymore (he teaches at Berkeley now). ASEing out of 18.02, a.k.a. getting full credit for it after passing an equivalent final exam, would mean I could pursue math a semester early like differential equations or linear algebra instead of reviewing what I already know (or maybe even take an introductory engineering course or other elective). I’ve gone through most of 18.02’s material once, and I took a course on the differential half of multivariable calculus last summer, so I’m hoping I can just pass by winging it at this point.

Other weird things that I committed myself to:  a real estate salesperson license. It shouldn’t be that hard, just a lot of time to learn the material so I can pass the exam. And I have to slog through a 75 hour timed course online before I take that. The good thing is I technically have until December until the online course times out, so I’ll be doing that when I have truly reached the pinnacle of boredom.

Speaking of boredom, some other goals and activities I’ve been trying to do when I have free time this summer: get a 99 on Oldschool. I have no idea why I started playing again (I checked in-game that I first made my account over ten years ago) but one thing led to another and me and three other school friends memed our way back into Gielinor. I’m talking we would Skype almost all day for a period of several weeks just grinding out the early game, fueled by our desire to simply keep up with each other. Now there is much less unity, but me and my very close friend still play from time to time. Since I’m at 87 fletching right now and it’s profitable (if only by a small amount) to fletch magic longbows until 99, I’m just going to string those anytime I have a few minutes of free time. Those minutes add up.

Another videogame-related activity that I seem to have lost all desire for: League. The only time I play is usually very late at night if friends are on. When I get to college, I’m assuming that I will get my ass handed to me with all the coursework, so that coupled with the fact that the game doesn’t really appeal to me much anymore means that I’ve weaned myself off pretty effectively. It’s still fun to watch LCS, though, don’t get me wrong. (Congrats to Doublelift for getting 1000 season kills!)

And finally, I got a DSLR. My first one, actually; it’s the Canon Rebel T6i. I literally just got it and haven’t even read the manual yet, and I’ve just taken a couple practice shots, but I feel like I’m already starting to fall in love. That coupled with two new whiteboards that I bought (a smaller one for my house and a huge one for my dorm room) would probably make for a revitalization in Youtube videos.

And I also want to learn Java further, but at this point when I finally get to doing that I’ll probably be learning it for my major anyway.

THERE’S NEVER ENOUGH TIME.

Okay, I’m going to end this blog post here because I really want to tackle this Math 0 problem: Let $a,b\in\textbf{R}$. Show that if $a+b$ is rational, then $a$ is irrational or $b$ is rational.
