At school I struggled with math, despite being keen. But with depression, social isolation and an in ability to focus, I did very poorly. About 5 years later I picked up my old algebra text book and worked thru it cover to cover, checking with my physics major friend occasionally. He thought I was doing very well, just overdoing it. Then came the burnout and the brain fog and the 'blues'. And I became stupid again. But you've inspired me! Will look into 'the math i missed'.

[@joshhallam2253]

I love the Dover Books on Math. After I graduated, I thought I would just keep studying math, so I bought myself a handful of them. I never did have the time or motivation once I started working full time and had a super long commute. I really wish upper division math books had answers and solutions to all the problems though. That would have helped. I had 1 semester of real analysis and tried to self study the 2nd half, but when you write a proof and aren't sure if the logic follows and can't see the solution, it is really frustrating and demotivating.

It's extremely hard to study math or science on your own while working a full-time technical job. Your brain is focused on something hard all day, and having to come home to it can really burn you out in a hurry. I've found myself having to drop graduate classes for that reason. In that vein, it's very easy to purchase books, thinking "I want to learn that!" In practice, they tend to pile up. Always buy an e-copy of technical books!

Here are some advanced and obscure topics in mathematics that I've had books on recommended, know researchers of, have researched personally, or have seen videos and papers on, that I nevertheless found interesting: 1) Model theory and proof theory. Some of my favourites topics in all of math and logic. 2) Spectral theory, which is the name of actually three theories. One on spectral sequences in alg. topology, one on spectra of operators in functional analysis and one on prime spectra of rings and schemes in alg. geometry 3) Stochastic polynomials in alg. geometry for computer graphics. Basically, random perturbations in varieties used to code in computer graphics and animations 4) Morse theory and its applications to numerical methods and data analysis 5) Cohomological methods in homotopy theory (book by Mosher & Tangora) 6) Infinity categories 7) Topos theory 8) Categorification of fourier operators 9) Orbifolds, vertex operator algebras & representation theory 10) Cohomology for complex & projective alg. varieties 11) Homotopy type theory 12) Differential forms in (sheaf and de Rham) cohomology theory 13) Representations of quivers 14) Discrete differential geometry 15) Applications of tensor algebra in statistics 16) Topological methods for dynamical systems and mathematical modelling of the brain 17) Representation theory for semisimple Lie algebras 18) Adelic groups in algebraic number theory 19) Topological problems with election systems 20) Tropical geometry 21) Infinite trees & hypergraphs 22) Determining if an antiderivative is elementary based on the orientability of its representative Riemann surface 23) Random matrices in computer graphics

Needham has written a book "Visual Differential Geometry and Forms: A Mathematical Drama in Five Acts". I picked it up because of how much I enjoyed his "Visual Complex Analysis".

Thanks for all you do and taking the time to share with us!

[@KashTheStampede]

I just started teaching grade school math again. I introduce some abstract algebra (non-rigorously, obviously), graph theory, combinatorics and symbolic logic. So much more math can be introduced as wonderful, simply stated problems than is introduced in the standard math curriculum. Math is much more a toy than a game, and the insistence of memorizing algorithms for complicated arithmetic kills the sense of math as a toy.

very interesting to hear someone talk about something they are passionate about, even if i not interested in the subject. i’m a senior in highschool and will likely never take a math class beyond basic algebra. not even trig. my major has little to do with math, but i still have all the respect in the world for the people willing to put the effort in to such a difficult area of study.

I feel like the field of Clifford Algebras is a branch of math that isn't as commonly known as it probably should be. They generalize real numbers, complex numbers, quaternions, and other hypercomplex number systems. Geometric algebra (and by extension geometric calculus) is a real Clifford algebra that has applications in computer vision and theoretical physics. Also, perturbation theory is an important field of applied mathematics and it deals with quantifying deviations in mathematical problem-solving.

[@sensorlock]

I started my BS as a Computer Science student, wandered into Applied Mathematics for a year, then switched back. I've definitely found the knowledge from that Abstract Algebra book you showed useful, but the most fun elective I took was on the knot theory sub-field of topology. The class was taught using the The Knot Book by Colin Adams. The thing that grabbed me was the multiple levels you could think through the problems at: topology, knot polynomials, and a physical piece of string.

For 1, I was taught by both Dr. Balanov and Krawcewicz themselves. So yeah, if you don't go to a certain school/program, you may not get to see some of these.

I'm currently in the final year of my network engineering degree and planning to go to grad school for telecommunications engineering. Can you suggest a good book for learning information theory and math related to signal processing? I see these two topics come up a lot in most telecom engineering syllabuses.

[@andrewaguilar6336]

For Signal processing you probably want to read real analysis and Fourier analysis. I haven't studied Fourier anaysis so I can't recommend anything, but some good intro texts for real analysis would be Understanding Analysis by Abbott, or Real analysis by Gaughan. I think Terence Tao has a two book series on analysis which coveres some fourier anaysis, but from the bit I've seen it is not as introductory as the other books i mentioned.

As someone going to apply for grad school in astrophysics l feel like I’m missing out not getting to study most of these fields.

Currently using the linear analysis and dummit/Foote algebra books

I am surprised you didn't show spherical trigonometry.:)

Thx for sharing!

"topics most people have never seen" *Shows linear algebra*

Books from Springer used to be absolute hardcore, very condense and advanced.

i remember a touch of auslander ,krysig

I would have killed to have a class on the topology on manifolds... I'm having to learn so much on my own to fill my knowledge gaps...

[@hansbaeker9769]

I only ever knew one grad student who specialized in functional analysis. The man was brilliant, but unfortunately he passed away from a heart attack at a relatively young age.

It took me a sencond to figure out that you were not calling math people blind.

[@feraudyh]

There are advanced subjects like K Theory and Non-Commutative Geometry which are a level above all of this.

[@kirbyurner]

I wonder what math most math people never see. Easy answer: ancient stuff (mostly studied by archeologists and maybe linguists). How about in a more contemporary vista?

cmon, group theory is first day in college when you are a math student
