    For programmers interested in classical mechanics, "The Structure and Interpretation of Classical Mechanics" is a highly unique - and outstanding - introduction to Lagrangian and Hamiltonian mechanics. Available free online:

    http://mitpress.mit.edu/sites/default/files/titles/content/s...

    The idea behind the book is to make the "mathematical notations be explicit and precise enough that they can be interpreted automatically, as by a computer." Since Sussman is involved, that means that they (and you, when you do the problems) write scheme programs.

    In a more traditional vein, _Mechanics_ by Landau and Lifshitz is (in my view) among the 2 or 3 best physics textbooks available. It's a great supplement for two reasons: (1) it takes a somewhat different approach to the material than most other textbooks (emphasizing the consequences of symmetries from the very beginning) (2) it's quite short, which I find to be very helpful when self-learning.

    "A number of years ago I became aware of the large number of physics enthusiasts out there who have no venue to learn modern physics and cosmology. Fat advanced textbooks are not suitable to people who have no teacher to ask questions of, and the popular literature does not go deeply enough to satisfy these curious people."

    It's as if he made the courses just for me! :) Thanks for sharing this.

    In 2004, Roger Penrose published "The Road to Reality: A Complete Guide to the Laws of the Universe" which is 1100 pages long. http://staff.washington.edu/freitz/penrose.pdf

    "One of my mother’s closest friends, when she was a young girl, was among those who could not grasp fractions. This lady once told me so herself after she had retired from a successful career as a ballet dancer. I was still young, not yet fully launched in my activities as a mathematician, but was recognized as someone who enjoyed working in that subject. ‘It’s all that cancelling’, she said to me, ‘I could just never get the hang of cancelling.’ She was an elegant and highly intelligent woman, and there is no doubt in my mind that the mental qualities that are required in comprehending the sophisticated choreography that is central to ballet are in no way inferior to those which must be brought to bear on a mathematical problem. So, grossly overestimating my expositional abilities, I attempted, as others had done before, to explain to her the simplicity and logical nature of the procedure of ‘cancelling’."

    There is a book that comes with the course: http://www.amazon.com/gp/product/046502811X

    The intro chapter is quite good ... very condensed material, but could be very interesting read.

    I'm the OP and originally posted the link and a brief review here: http://www.latestlesson.org/the-theoretical-minimum-modern-p.... If anyone has other suggested physics materials for those who are not professional physicists, I would be interested in reviewing them for our site. We're trying to create a comprehensive list of resources for STEM learners.

    I've watched a few of these just for fun. They are very watchable even if, like me, you don't have the first clue about the actual mathematics he uses. He explains enough of the physics in words that you can just let the forumlae wash over you and not worry about it.

    The maths is kept into self-contained bits, so a lecture will typically be 40 minutes of words and pictures, then 20 minutes of calculation. I'm sure if you do get the maths then it will be perfect for you, but I encourage you to watch it anyway.

    Overall, highly recommended, especially the cosmology ones.

    EDIT: actually my memory is probably biased towards the cosmology course. I imagine the classical/statistical mechanics stuff does have a lot more maths running through each lecture.

    I have been following his lectures for quite some time. Hat's off to Leonard Suskind.

    I did Quantum Mechanics, Classical Mechanics, and now General Relativity. All of them enlightening, provides pure joy that only science can. And he is incredibly easy to follow, despite being a leading and esteemed Physicist of modern times - falls in similar class as Hawking. (The holographic principle anyone?)

    For those interested in QM I highly recommend this intro Quantum Mechanics for Engineers http://www.eng.fsu.edu/~dommelen/quantum/

    I've been reading this and it's fantastic - approaching the subject from the tools needed to understand the way the material works mathematically (Lagrangians etc) rather than as a series of separate physical problems is an excellent idea.

    The video lectures in combination with the text would, I think, be a great subject for a regular meet up - its dense enough that there's lots to discuss but doesn't have too many prereqs. Anyone in London interested? Shoot me an email if so (Thomas dot m dot McGrath at gmail dot com)

    This is interesting, I've watched Professor Susskind's lectures on Quantum Mechanics and they were very good. Was able to understand how QM actually works for the first time.
  • by codezero on 5/14/13, 6:45 AM

    I'm going to check this out, but the cadence of the lectures (just by looking at Classical Mechanics) seems pretty high for a 1.5 hour lecture, getting to Lagrangians in the third lecture seems pretty advanced for a survey of the subject especially targeted at enthusiasts.

    A lot of the stuff covered in this series of courses wouldn't even be touched in a lot of undergrad Physics programs, outside of a small survey/project as part of a more broad course.

    Oh my, this is exactly what I was looking for. I'm going to dive in into this but does anyone maybe know about similar online resources you could learn some more advanced physics topics? Btw, Susskind is such a great man, love his way of work and persistence.

    You can probably do better by going through Feynman's lectures. And maybe also his QED.

    This is very interesting

    As someone that has studied physics in an undergrad course, and who has learned a lot, but is disappointed that these courses don't go very far, this is very interesting.
