>>338 Good thread OP.
How do you anons stop making basic blunders in exams? I fuck up the basic math and make stupid mistakes, and then I end up ruining the whole question. My grades are suffering because of it, even though I have a good grasp of the advanced stuff.

Does anyone here have maths as a "hobby"? If so, what do you do, just solve textbook problems for fun? Or is there something like Github for mathematics where amateurs can contribute to open problems?

And to be honest I never really figured out how to deal with it, I just lucked out and managed to not make enough blunders to pass. But something that kind of helped was really slowing down and doing nearly every calculation by hand, writing down all the steps for the question instead of just diving in, etc.

Do any of you know a good collection of geometry problems? Something that I can think about when I have nothing better to do. I want to train my visual thinking.

>>748 i doubt theres any mathematical value besides proof verification. contrary to popular belief, mathematical thinking is precisly what cannot be formally reduced to modus tollens. the likes of agda or lean may be of interest to logicians or TCSists, but can hardly assist mathematicians with their work

The standard solution is based on von Neumann's work and predates category theory. Cantor's naive sets are renamed to classes. Classes are partitioned into sets and proper classes. Sets are those classes that can be built up using ZFC, which removes unrestricted comprehensions. You can no longer take "all X [with P]", you have to take "all X from S [with P]" where S is already a set. The question becomes whether the class of all sets is a set. The resolution to Russell's paradox is to provide the negative answer by becoming the proof that the class of all sets is a proper class rather than a set.

>>9033 I would be interested in this too, as I have already forgotten much of what I studied in university. Would Anki help?

Anyone here reading more "historical" mathematical texts? I've started reading through Bourbaki's theory of sets, just to kill some time until I go to university. Its a little incomprehensible to a brainlet like me, but its very nice to read about mathematical concepts that don't get much or any use these days.
>>7466 Amateur mathematicians aren't taken very seriously by academics, because a lot of quacks come up with "solutions" that are blatantly incorrect. All of the open problems require a lot of study to even understand, or exist in highly specific fields. If you want to study math for the hell of it, just pick up some books on the fields that interest you and read through them.
>>9033 Not sure if any website with exercises beyond high school level math exists. Getting a textbook in the topic you'd like to brush up on, and looking at the exercises in there should work. Skimming through the chapters might also be a good way to see if you've forgotten anything too.
