It's definitely not the best resource, but math intuition is what I'm promoting on https://wordsandbuttons.online/

I think, with modern tools, you need math intuition more than computational skills. That's why my site is all about interactive experience. There are no proofs or problems but a lot of things to tweak and drag.

Helps to keep in mind Jeff Raskin's "theorem" - "Intuitive equals familiar". Although displaced from its original UI context, the reading of "gaining intuition = gaining familiarity" is spot on.

So if you're looking for intuition, you're looking for deep familiarity which means spending the time/effort it takes to get familiar.

Resources don't help much as they're almost always about someone else's "intuition". Struggle that leads into false turns and force you to backtrack help a lot more I think.

An example - some time ago, I told some colleagues that they've been dealing with convolution even before middle school .. which surprised them. Multiplying numbers is the same operation as convolving their digit sequences. But if you didn't fool around enough with multiplication, or try to relate it to algebra, polynomials, and such, this can be hard to see.

I feel you need to rethink your goal. it's like you're trying to finding missing chapters from an undefined book. Try to be around problems that requires a high degree of math skills to solve. let the problems drive you. intuition is usually built by spending hundreds of hours thinking, eating, and drinking the problems you're truly interested in to arrive to a solution. If you spend enough time doing this, you'll kn…

There's a loophole. You read about people like Gauss who had insights long before they became math students. There's something to dig there.

> In high school I did the lowest tier maths and then jumped in the deep end by doing a year of electrical engineering. I’ve now done those harder math classes but I feel like there’s holes here and there. I think when I took physics it really brought out these flaws and lack of intuition.

As a mathematician, I say: what you lack is not math intuition, but math knowledge. Read really hard math textbooks and solve exercises. This is the only way known to me to get better at math.

aside from 3Blue1Brown :

I think category theory will give you an unique point of view of math, also basic logic and philosophy are very important for a good and solid foundation on math intuition.

https://arxiv.org/abs/1803.05316 along with their youtube lectures.

very basic but refreshing:

Related question, anyone know any good resources for learning and developing intuition in Abstract Algebra? Especially ones that explain it well, like Calculus Made Easy did for Calculus. AA is a prereq for cryptography, category theory and and other areas of interest for CompSci. I asked this a few weeks ago but at an off peak time and not many folks saw the question. But I know HN probably has good recommendations…

Take a look at "A Book of Abstract Algebra" by Charles Pinter. It's published by Dover, so very affordable. I've seen it criticized as too verbose, but that worked for me.

It has been my experience that complaints about a source being "too verbose" rarely come from people learning the subject.

Gauss definetly used a cheat code. Calculating before starting to talk, fixing errors in payrolls at age of 3... numbers came more naturally to that guy than talking.

If something is to dig here is that the earlier you start the better you will be.

Every field has exceptional people, things just come naturally to them. Recently I've been watching some videos of Kim Jung Gi on youtube (warning, some of his videos are not safe for work). In a world of super talented artists, Kim is on a whole another level. Apparently he was exceptional, even as a child (though he does draw a lot). Ramanujan woke up from dreams in the middle of the night, wrote complex Math proofs and went to sleep. And so on.

I guess the loophole here is simply being born with talent :P
