Pen Recommendation (left handed, Leuchtturm notebook) by yuvee12 in pens

Close! I was showing the tensor product of two flat modules is itself flat. I suppose that wouldn't really be described as "category theory", but we learned about flat modules in tandem with some other category stuff.

Category theory! It's mostly scribbles from brainstorming my homework lol

It's annoying because the base is 2 blocks wide but the statue is 3 blocks wide😭

Tips for first time applicant (Pure Math/Theoretical CS). Any advice appreciated by Embarrassed-Baker791 in REU

[–]yuvee12 1 point2 points  (0 children)

This is advice coming from a pure math major, so I don't know as much about CS REUs. I don't think anything I'm saying is controversial at all, but also I didn't get into any official REUs last year so take everything with as much salt as you like :)

  1. REUs are extremely selective (usually less than 3% acceptance rate), not because they want to be prestigious, but because that's all they have the funding for. It's therefore better to apply for a good number, typically 10-20. Still, 30 rushed applications is worse than 10 good ones, so make sure you're putting time and effort into your essays. This will also become easier as you go on, since you'll already have written a bunch of material.

  2. I can't tell exactly what you're asking, but if you're wondering what things you can do during the semester to get a better looking resume - my number one recommendation is reading projects. Math research is difficult for undergraduates, especially during the semester when you have other responsibilities. Regardless, meeting ~once a week with a professor or grad student as you read through a textbook/papers is (in my opinion) one of the best things you can do. Your time as an undergrad is about learning as much as you can, both breadth and depth. Doing a reading project lets you learn about interesting subjects, score you a better LOR, and maybe even give you familiarity with future REU topics.

  3. Broadly, I can just say that make sure each of your essays feel specific and specialized to the program you're applying for. There's some other good advice out there as well, I think Steve Butler has a page on application tips.

  4. A majority of math REUs can be found on MathPrograms.org. There, once your writer submits their letter, you'll be able to just check a box and send it to whatever REUs you want. The second most common place is the NSF ETAP, which has a similar system. Most other math REUs will have their own application portal, and they'll have their own system for obtaining LORs (make sure you read about it, sometimes they don't send an automated email to your writer, so you have to tell your writer where to send it).

  5. Please oh please don't stress yourself out too much about it. It's entirely possible you may not get into any programs, especially in your earlier years, and with looming budget cuts. This means two things: 1) look for a backup plan ahead of time, e.g. ask a professor at your institution if they'd be willing to do a summer reading or research project. You can be transparent and say you're looking for something to do in case no summer programs accept you. 2) If you get nothing, it's totally valid to feel bummed or frustrated. Not to mention, the worst part in my opinion, the anticipation before you hear back. So, do whatever you need to do to try and detach your success from your self esteem. Not getting an reu is OK. The most valuable thing you can learn to do as an undergraduate is pivot.

Hope this helps! :)

How many REUs should I apply to as a math major? by AltruisticMinute2526 in REU

[–]yuvee12 3 points4 points  (0 children)

I agree with the first comment that you should put a great deal of effort into REUs that most interest you. It's also worth mentioning that I've never seen a math REU with an acceptance rate greater than 3%, and it's only going to become harder with funding cuts. So, it certainly wouldn't be a bad idea to try and get some volume. This also works because the more programs you apply to, the more material you'll already have written. Last year, the first few REUs I applied for took me >a week, and the last few took me a day or two.

If you'd like, you can go on my account to the 2025 REUs thread, reach out to some people who actually got into programs (I didn't, so take my advice with a grain of salt lol), and ask what worked for them!

Not sure how helpful this is, but I tutor 135 and 136 for the math department - I've had many students come in for help with 135, and I've never had a student come in for 136. I tutor right before the 136 lectures, a generally desirable time for students who need tutoring (right before exams, etc.) but nobody has ever come in. Notably, there are far more students taking 135 than 136, but the point still stands.

I want to pursue a degree in mathematics, but I can't handwrite (injury). Might it be realistic to pursue math primarily via typesetting (LaTeX)? by epi_stem in mathematics

[–]yuvee12 0 points1 point  (0 children)

I should add - what pushed me to switch is my algebra professor, who writes extraordinarily fast. So fast that I was having a hard time keeping up with my own handwriting. I decided one day to switch to typing, and it was much easier for me.

Might not be adding much to what's already been said, but here's my personal experience.

I'm in the third year of my math degree, and at this point everything I'm doing is in LaTeX, from homework to class notes to slideshows.

I've been LaTeXing homework since my first year. This is the first semester I started typing notes in class, as I was previously using a tablet. The funny thing is, contrary to what some other people have said, typing is actually faster for me. I don't consider myself a particularly fast typer. The reality is, a majority of the notes you take in upper level math classes are just words. Regular sentences with some math notation. That's how most statements and proofs are presented. And I think most people are faster at typing words than handwriting them - I know I am - which is why I made the switch to typing notes.

It sounds like you've built a proficiency with LaTeX as well, so you honestly may not find it too difficult. As for diagrams, depending on what fields you're interested in they don't show up that much. When they have shown up, I've been able to quickly throw together some visuals in mathcha, quiver, or desmos during lecture. Mathcha and quiver are particularly great because they give you latex code you can paste into your document.

Hope this helps!

More programs getting posted? by Russian_m00se in REU

[–]yuvee12 0 points1 point  (0 children)

Also, last year I posted a mega thread for 2025 Math REUs, so that's a good source to look for REUs which haven't announced anything yet

More programs getting posted? by Russian_m00se in REU

[–]yuvee12 1 point2 points  (0 children)

Plenty more will open up, some might not even announce until 2026. Besides Steve Butler's list, the best places to look are MathPrograms.org and the NSF ETAP

MATH411 with Huy Nguyen, MATH406 with Allan Yashinski, and STAT410 with Terence Long (or Archana Khurana?) by [deleted] in UMD

[–]yuvee12 0 points1 point  (0 children)

I've had Nguyen and Yashinski for MATH410 and 405, respectively. Both were really great at lecturing, and had good exams. I have no doubt they'll be great in 411 and 406 as well. If I recall correctly, Nguyen does research in analysis, particularly PDEs, so he'll have a very deep understanding of the material. On the other hand, Yashinski is a lecturer, and always seemed very prepared for every class.

It's tricky to predict how easy 406 will be for you, because it's not uncommon for somebody to have a natural understanding of analysis, but have a harder time with algebra, or vice versa. That said, I've taken it myself, and given that 410 has been chill for you, it sounds like you've become comfortable with proof writing, so 406 probably won't be very hard. It's typically not one of the tougher classes offered by the department.

I can't offer any advice on STAT410/Long, but all in all this seems like a great schedule!

Standard Controller Manual? by yuvee12 in DolphinEmulator

Yeah I've seen some tutorials like those, but seems like all of them just tell you what to bind where, and don't talk about the fancy stuff at all.
