oh god the programming task for today was so annoying. I was supposed to process the MIT database with ECG records, and the annotation part of it was hell. after three hours I finally did it but the anger I felt at that time put me seconds away from throwing my laptop out of the window lmao

a recent success is that I calculated the rank of the module that I am working with, the problem is almost solved! when I told my advisor about it he looked so happy, he said that maybe he should start looking for another problem for me to ponder, it was so satisfying. I have a thing for mentors. at each point in my life for which I had a mentor who would teach me my special interest the progress I was making improved significantly and those were always the happiest times of my life. I am not sure if my advisor will stay with me to further show me a way into the research, but it certainly feels like a possibility

today I did some algebraic topology and differential geometry, I'm trying not to fall behind with the material even when I don't feel like studying

next week the easter starts, so I will probably have to visit my family. it's an interesting feeling to see my sister all grown up, there is still the image in my head of when she was barely a teenager and we didn't have much to talk about. now she is almost 18 and the significance of the age difference is nearly gone. when she start university it will be even less noticeable as she will understand what I mean by "fuck my life it's exam session season" lol

for about a week I've been trying to eat more healthy food, it's going fine so far. my biggest problem is that I'm eating way too much sugar but undereating in the general sense at the same time. I'm trying to incorporate more fruits and vegetables into my diet, as well as different kinds of nuts. it's so important to be properly nourished for math and yet I neglect it so much

yesterday I had a conversation with my friend and he said that his vision for doing math is working on some huge open problem such as RH. obviously you do you, but this sounds like such a depressive idea to me lol. chances of solving something like this are almost non-existent, that's such a waste of time to work on something like this for 10, 20, 50 years and make no progress. I mean, it certainly would feel nice to prove or disprove something like RH, but I'm perfectly fine with reading papers and answering all the questions I can anwer, which might not be huge and famous but I'm pretty sure creating those small pieces of theory will be useful to somebody one day

i've been working on it with my boyfriend for a while now and–

One of my favorite thing I’ve learned about animals studies is that you should avoid using colorful leg bands when you’re banding birds because you can accidentally completely skew the data because female birds prefer males with colorful bands

Apparently if you put a red band on a male red wing blackbird his harem size can double

So like you can completely frick up the natural reproduction of a group of birds by giving a guy a bracelet so stylish that females CANNOT resist him

Hey, im second semester math undergrad, do you recomend any book for calculus?

hi, unfortunately for first year analysis/calculus I used mostly the resources given by the professors, however, when I did use textbooks I really liked Walter Rudin:

as far as I know, many people recommend Apostol's book, which looks very good and if I was to choose a textbook for myself right now I would definitely try this one:

other than textbooks, if you like learning math from videos check out this channel:

I got a proof wrong on an exam. No points. 

Then, I thought about it for fifteen minutes outside of the exam, wrote it down, nailed it. 

I showed a classmate and told him what happened. He looked frustrated. He’d clearly had this happen before, too (haven’t we all?).  He said, “Don’t you hate it when that happens?”

I almost said yes. What the h*ck!? No. No, I do not hate it when I can fathom a deeply abstracted concept in mathematics. I never hate that. I the opposite of hate that. Expecting myself to immediately understand topics like this is unrealistic. I’m proud of being able to do it at all. Who cares if I did it in the exam or within the next hour? I DID IT. It’s mine now. I can do it whenever I want. Missing points on that problem doesn’t take the knowledge out of my brain. How dare I be taught that my knowledge is useless because I didn’t have it right at that moment. It’s just as good now. 

Education is not about the arbitrary numeric number ascribed to your ability to do things quickly in an arbitrary, restricted time interval. Education is about being able to do progressively more things, to understand progressively complex things. 

Tenacity and challenging yourself far beyond your limits is a hundred times more important than getting good grades. Because, when you’re one of .4 percent of the population who possess complete knowledge on a very complex topic, nobody cares how long it took you to do it, or how well you did it the first time you tried. 

Grades don’t discover new mathematics. Mathematicians do (even the ones who failed a basic topic in mathematics because their base way of thinking was too complex). Grades don’t advance medical research. Scientists do (even the ones who had to apply for their PhD programs 3 times in a row before they got accepted). Grades don’t make science fiction into real-world technologies. Engineers do (even the ones who dropped out of school because they wanted to build things, not talk about building things). 

Knowledge is power. Skills are power. Grades are constructs. Never trade actual understanding for a semblance of understanding. 

13 I 2023

two days ago I went to the 0th term exam for commutative algebra and received the highest possible grade!

the thing I noticed when studying for it was that the topics that used to be fairly ok but not very clear became completely intuitive. the best example of this would be fibers of maps induced on spectra. it feels so good when after trying to understand something for two months everything finally clicks and I obtain a deeper level of understanding

also I realized that making pretty notes actually doesn't help at all, so I switched to making more messy, natural ones. maybe I can no longer look at them and admire the work of art, but I think the principle behind it is that the more I focus on making my notes pretty the less attention I pay to actual information processing

so maybe these ^ don't look as good as they could and they are probably hardly useful for anyone other than me lol but the benefit is that I started learning really fast compared to how it was going when my notes were a work of art

currently I am studying sheaf cohomology and preparing for a complex analysis test (it's next week). I have two courses left to pass and I would like to ace them too, although that's rather unrealistic

the second batch of topics for complex analysis includes: order of growth of entire functions, analytic continuation, gamma, zeta, theta functions and probably elliptic functions. significantly more sophisticated than the first part of the material. for the course on algebraic methods, everything is hard lol I am waiting for the moment when homological algebra and sheaf theory become intuitive

next semester I am going to take algebraic topology (fucking finally), differential geometry, number theory, statistics and algebra 2 (mostly galois theory). I have never taken 5 courses in one semester so I'm very scared
