What do you big brains have to say about starting STEM later in life? I'm a humanities fag who is almost thirty with prestigious degrees from US top whatever schools. I feel like I missed out on the science bus. I would like to go to med school or learn software engineering. What is my prognosis?

OP here. Not privileged at all. I came from a lower-middle class background but did stuff like Calculus AB and Physics C and all that jazz when I was younger and got good grades and got a scholarship. I just wasn't disciplined enough for STEM the first time around. I can't leech off my parents forever. Any other ideas?
>>
>>16584411
>What is my prognosis?
It's obviously not a great idea if all you care about is money. You only change careers later in life because your previous career didn't work out and you have no other choice, or because you're interested in a new career for reasons other than money.
>I would like to go to med school or learn software engineering.
A lot of people get into med later in life because they get disillusioned with their careers and would rather spend their time having a direct, positive impact on people's lives. Going med to begin with is a rather bad financial decision overall i'd say, the amount of money you make can be quite big but isn't all that impressive given the sheer time commitment and lifestyle difficulties, generally if you're smart enough to get through med school and become a doctor you're smart enough to make better money in less time in other fields, you need to want to be a doctor.

Software engineering, not my cup of tea, no opinion.

>>16584411
Don’t go into software. I finished my BS in ME at 28 after having to drop out the first time around (untreated bipolar disorder). Unless you have great soft skills, software has has too many turboautists that can out code you, and AI is going to eliminate everyone below the 50th percentile. STARTING pre med at 28/29 can be tricky. Assuming you have all gen ed and elective credits, it’ll still take 2 years to finish pre med. 4 for med school. 3-7 for residency. You’ll be at 37-41 before you become a full fledged doctor. BUT- if it’s something you really think you’d love, go for it. The money is still decent, and you really will make a positive impact in a lot of peoples lives. And at some point you’ll be 41 anyways. Ask yourself- would you rather be 41 in your same field, or 41 and a doctor?

>New Calculus
The following is an excerpt from Peter J. Olver's alternative calculus lecture notes (https://www-users.cse.umn.edu/~olver/ln_/cc.pdf):
>"I started thinking about the topological definition of continuity, [12]. In brief, a function is said to be continuous if and only if the inverse image of any open set is open. This sounds very simple — and certainly simpler than the limit-based definition used in calculus. And I started wondering why not try to develop basic calculus using this as the starting point, and, possibly, eliminating all references to limits, epsilons, and deltas while still retaining rigor. And, after some thought, I realized it could be done. Continuity is basic, and limits, including limits of sequences, and derivatives follow from it in a reasonably straightforward manner, while bypassing epsilons and deltas entirely! You will see the results of this line of reasoning below.
>Not only can the development be made completely rigorous, I believe it is more elementary and eminently more understandable by the beginning mathematics student, who will be better able to appreciate the rigor behind the calculational tools. Moreover, this approach introduces them to the basics of point set topology at an early stage in their mathematical career, rather than having to start from scratch in a later course in the subject or in preparation to study real analysis".
I sure hope the "new calculus" of the distant future, "Neo-Stewart", will be something along this lines, maybe together with some non-standard analysis (a là R. F. Hoskins, i. e., https://archive.org/details/standardnonstand0000hosk) or more filters instead of limits. There's also honors calculus textbooks from the past like Thurston's which argue that it is more elegant and at the same time easier and more illuminating to think in terms of [math]\epsilon[/math]-neighborhoods instead of the traditional but dry full [math]\epsilon{-\delta}[/math] statements:

I'd like to preface this post by apologising in advanced for asking a question that has probably been asked a thousand times already, but I don't know where else to ask. I don't use r*ddit, or d*scord, and none of my friends are into mathematics.

My situation:
Intermediate Algebra (Blitzer) - done all odds, and all end of chapter tests
College Algebra (Blitzer) - done all odds, and all end of chapter tests
Precalculus (Blitzer) - done all odds for trig only
Book of Proof (Hammack) - 1/3rd through, doing all odds
How to prove it (Hammack) - 1/5th through, doing all questions (found solutions manual online)

My goal:
Precalculus (done) -> Proofs (work in progress) & Calc (I am here!) -> Analysis -> Linear Algebra -> Abstract Algebra -> Number Theory

I need a calculus book that fits these criteria:
- Good for self-teaching, so must have many examples, questions, and answers to at least all the odds, or a solutions manual.
- Some rigour, but not too much as I'm not fully confident with proofs. I do have a little bit of experience with proof by induction.
- No physics, no engineering. I don't care about applied mathematics.

Thank you.

Not really. Undergrad math is very elegant. At the end of undergrad, you'd be doing what? Stuff that has largely been done in early 20th century. But current math is just extremely ugly, and disorganised. You would simply have to take results from subjects you know nothing about at face values. What you'd be doing would seem to have absolutely no correlation with real life. You'd be reading 10 page long proofs on results that you have no idea why anyone would care about. I mean even stuff like functional analysis, differential geometry and whatever people learn at the late undergrad level is still fairly motivated and organised, but bleeding edge math is just absurdly soul crushing. That is, unless you are number theory autist.

Wrong, it is correct.
Human eye or brain responds more to green than red.
Yellow is a hue that is a mix of green and red.
So if you send yellow light with same measured power as you send green, the green should be brighter for humans than yellow.

You have yet to notice that autism is the new normal. Our cultures raises, educates and (in)forms "people" who only acknowledge literal descriptions of objects following the socially constructed rules of logic, reason and language as "real". For example: "love" can not be observed as an object therefore to an autist "love" is a schizo idea. Although that doesn't explain why autists like evolution and big bang theory so much because those ideas are not observable as an object either.
