How to Become a Good Theoretical Physicist

As someone who considers himself something of an autodidact and who is always trying to learn new stuff, I really appreciate a resource that can point at a bunch of stuff and say (even in an approximate sense) "do this in this order". It really does make a difference.
Beginning your study of cognitive/computer science with GAI could be frustrating and fruitless, just as would be beginning your study of physics with superstring theory.
There are probably well-written and interesting GAI books/articles for laypeople, though, analogous to Brian Greene's excellent books on string theory.
You say "mathematics, cognitive science, and computer science at increasing levels of sophistication.". That's probably true, I'd recon a fair bit of biology, chemistry and physics is most likely also needed.
My question, though, is what specific branches of said subjects?
After a PhD in theoretical physics then 20 years as a s/w developer I decided to get some of my chops back. You can read and nod about stuff but until you face a blank sheet of paper you don't know if you really understood.
+1 for Penrose's "Road to Reality"
Also a huge fan of Eric Poisson's lectures (basically free textbooks) http://www.physics.uoguelph.ca/poisson/research/notes.html
Short description of getting my chops back: http://nbodyphysics.com/blog/2015/02/28/learn-physics-with-t...
Sadly I have no intention of studying theoretical physics. If anyone could point me towards something for theoretical computer science and algorithms I would be most grateful
Cheap trick: google up university course pages like [1], look at the syllabus and get the books listed. MIT's OpenCourseware has lots of stuff [2].

However, I think that professors generally are very willing to help people who are interested, even if you aren't a student. Actually as far as I can tell usually they don't even ask if you are a student.
Greek letters are used a lot. Learn their names,
otherwise you make a fool of yourself when giving
an oral presentation
One thing that surprised the heck out of me is that we don't pronounce Greek letters like the Greeks do.Example: tau sounds something like taf in Greek.
(that's all I got :-)
As a side note, that class was absurdly easy because I already knew almost all the vocabulary. The classical grammar is quite different though, and more complicated.
There is very much more content in these lectures than is covered in the two books.
Introduction to Plasma Physics by Francis F. Chen and Fundamentals of Plasma Physics by Paul Bellan are good next-step texts, and this crowd in particular might enjoy Birdsall and Langdon's Plasma Physics Via Computer Simulation
Also on the computational topic, Kane S. Yee's 1966 paper "Numerical Solution..."
Regarding his comment about hearing from amateurs who think they've solved the world, that is something I've heard from a lot of physics professors, that they get a lot of emails with crazy stuff like this: http://i.imgur.com/QTt6ZTq.gif
Why does that happen in physics and not chemistry, bio, econ, comsci or any other subject?
I think that math/physics are more accessible to the layman. I know where to go if I want to get deeper into this subject.
I really don't know how to start becoming an amateur chemist or biologist. I've wanted to learn more about synthetic biology and gene therapy, but it's not as simple as cracking open a math book or going to a dev bootcamp. I wish these resources existed though! My best guess is because exploring chem and bio have bigger resource requirements like lab space.
In reality it's literally impossible for most people to imagine how hard the math is - because an undergrad physics or engineering degree is barely even a warm-up for it.
I'd love to see a TV show that made it clear just how challenging the math is without reducing it to the usual storytelling.
Popularisation can be great, but maybe it would be good to get a realistic appreciation for the raw version into the public narrative.
In applied CS, instead of emailing professors people just post their stuff on the internet. Sometimes it gets wildly popular. How do you think PHP came around?
Another interesting resource would be Penrose's book: "The road to reality".
It starts with basic maths and go all the way up to relativity and the standard model.
But, someone sharing their knowledge and path in a no-nonsense approach, sure helps a lot.
Are there any other similar guides for other fields?

But here's a simple starting point: https://en.wikipedia.org/wiki/Portal:Mathematics
That said, I think we should interpret "how to become a good theoretical physicist" as "how to gain the competencies that are expected of s theoretical physicist."
A bad theoretical physicist is one who only understands enough to sound smart to their friends. AKA, a crank.
[1] I mean "crank" in the second sense shown at the Merriam-Webster dictionary site.

Later, the advice on how to become "good" was re-designed to look better, but split the content across multiple pages (http://www.staff.science.uu.nl/~gadda001/goodtheorist/).
"set up only for those who wish to become theoretical physicists, not just ordinary ones" --- use of 'ordinary' instead of 'experimental' is intentionally condescending, hopefully for sarcastic effect
"very best, those who are fully determined to earn their own Nobel Prize. If you are more modest than that" --- I'm not sure if this is actual encouragement or a joke. But the following:
"finish those lousy schools first and follow the regular routes provided by educators and specialized -gogues who are so damn carefully chewing all those tiny portions before feeding them to you." --- Must be a joke. Nobel prizes are not awarded to individuals these days, they go to collaborations. There is no way to get into a collaboration, or likely a PhD program without an undergraduate degree in Physics. Legally not allowed in many European countries to join a PhD program...
"More than rudimentary intelligence is assumed to be present, because ordinary students can master this material only when assisted by patient teachers." --- if this isn't sarcasm, then this guy is a monstrous prick who just decided to insult the 'rudimentary' intelligence of all Physics undergrads who deigned to actually attend college. Again with the 'ordinary'.
The opening paragraph continues the authors apparent disdain for school in general:
"But what if you are still young, at School, and before being admitted at a University, you have to endure the childish anecdotes that they call science there? What if you are older, and you are not at all looking forward to join those noisy crowds of young students?"
Which is a bit humerus considering the importance he himself places on fundamentals with:
"solid foundations in elementary mathematics and notions of classical (pre-20th century) physics. Don’t think that pre-20th century physics is “irrelevant”"
If it isn't sarcasm, then I have no idea why the author has decided to be so acerbic in his notation. I'm giving him the benefit of the doubt that he doesn't actually mean to insult basically the 99% of physicists who don't show up in "Brilliant Mind"-esque movies.
edit: From his CV:
* Gymnasium-Beta, Dalton Lyceum, The Hague, 1964 * Physics and Mathematics, University of Utrecht * Kandidaatsexamen N1, 4 July 1966 * Doctoraal examen Theoretical Physics, 10 October 1969 * Promotie (PhD thesis) on the subject "Renormalization Procedure for Yang-Mills fields", 1 March 1972
i.e. He did basically all this stuff he is brushing off as worthless. As in going to classes, with teachers, at an undergraduate university, before applying for a PhD program.
> "set up only for those who wish to become theoretical physicists, not just ordinary ones" -> -- use of 'ordinary' instead of 'experimental' is intentionally condescending, hopefully for sarcastic effect
If you'd finished the sentence, you'd see: "but the very best, those who are fully determined to earn their own Nobel Prize. "
He is constrasting "ordinary" with "the very best". He isn't talking about experimental physics -- that's not his field.
> "finish those lousy schools first and follow the regular routes provided by educators and specialized -gogues who are so damn carefully chewing all those tiny portions before feeding them to you." --- Must be a joke. Nobel prizes are not awarded to individuals these days, they go to collaborations. There is no way to get into a collaboration, or likely a PhD program without an undergraduate degree in Physics.

The beauty of theoretical physics (and math) is that you don't need any expensive equipment or overpriced tuition. Just books and people to talk to. Both of these are available free (except some books cost $$$), on the Internet. That's enough to get started.
> "More than rudimentary intelligence is assumed to be present, because ordinary students can master this material only when assisted by patient teachers." --- if this isn't sarcasm, then this guy is a monstrous prick who just decided to insult the 'rudimentary' intelligence of all Physics undergrads who deigned to actually attend college. Again with the 'ordinary'.
It's a simple fact: Smarter folks can get farther without as much guidance from teachers.

Common K-12 schools in many countries generally teach science and math very poorly. This is not a controversial statement.
Colleges are full of 18-22-yr-olds, many of whom are there to party; not a comfortable environment for some 30+ year olds.
> Which is a bit humerus
You seem to have a bone to pick.
> considering the importance he himself places on fundamentals with: "solid foundations in elementary mathematics and notions of classical (pre-20th century) physics. Don’t think that pre-20th century physics is “irrelevant”"
What does that have to do with the high school and college learning experience?
>i .e. He did basically all this stuff he is brushing off as worthless. As in going to classes, with teachers, at an undergraduate university, before applying for a PhD program.
The into goes to lengths to explain the sort of person who doesn't fit into school, and would benefit from an autodidactic alternative. For everyone else...there's school. I don't know why you have such a chip against the possibility of thriving outside of college... too much student loans got you sour grapse?
His words feel condescending to me.
I know from the inside that _these_ actions are the most probable path to success. If some hot shot high school student reads his note, I can see them deciding that they are "brilliant mind" material and then start pursuing this course of action seriously. In my opinion that is a borderline surefire path to failure. College campus is _the_ place to learn physics: you learn physics from casual bar discussions about the fluid dynamics of beer, telling a pretty girl why stars twinkle and planets don't, explaining to stoners why cigarette smoke is blue off the cig and then grey when you exhale, pre-exam pizza binges, adding strobe settings to your dorm lights, and late night campus laser graffiti with your mates and professors. Not from lone wolfing down a textbook with a blackboard.
It's perfectly possible for him to convey his message without "ordinary", "childish", "noisy", "rudimentary", "tiny portions" etc. And if he's just putting together a guidebook for entertaining your interest in Physics, then that's cool. But saying this is the way to get a Nobel is ridiculous... hence my original comment about dripping sarcasm.
Also my original comment was just getting down voted (and someone asked for clarification) so I expounded.
And no, I got a ride through college.
He's not aiming this at practicing physicists. He says early on that, if you want to be a physicist, you should enroll at a University. He says in the Questions section that you'll eventually need a degree.
This is aimed at people who can't or won't. The sarcasm is intended to appeal to the "well intended but totally useless" amateur physicists that regularly send him crackpot theories. It's a common refrain from such individuals that they are held back by the establishment.
What he's trying to convey is the amount of information that one needs to master to be taken seriously as a theoretical physicist. His intention is both to put off those that have read a popular science book and now know it all as well as encouraging those that are actually serious by giving them some structure to their learning.
The author isn't expressing his disdain for school, but the disdain he perceives in the people who keep e-mailing him with the simple answers to deep questions. "Okay," he says (I'm paraphrasing wildly here), "you may be too cool for school, but if you don't have at least a firm understanding of these basics, you won't even be able to understand why you're wrong when you, quite inevitably, veer off into the muddy mire of misunderstanding."
He is most assuredly not denigrating experimental physics, nor is he saying that the ordinary educational process is a waste of time and effort. (This is not meant to encourage autodidacts in any way.) He's even hinted that the "lies to children" -- those models that seemed to work for a very long time in the pre-GR/pre-quantum world -- aren't nearly as useless as people might think they are, nor are the scientific processes that led to those models.
So, yes, he is being quite sarcastic here, but the sarcasm is pointed in a completely different direction.

Reminds me of GOOD Music [0]
I can tell you of my own experiences. I had the extreme luck of having excellent teachers around me. ... It helped me all the way to earn a Nobel Prize.
But I didn’t have internet. I am going to try to be your teacher.
It is presently set up only for those who wish to become theoretical physicists, not just ordinary ones,
but the very best, those who are fully determined to earn their own Nobel Prize.
This is a site for ambitious people.
I am sure that anyone can do this, if one is gifted with a certain amount of intelligence, interest and determination.
