How does this compare to Susskind's "The Theoretical Minimum"?

Susskind's is much shorter and goes into very little detail. It's really intended to give you a foundation for learning physics, while Feynmann's is meant to teach you lots of physics.

It is awesome how while the page is loading you see stuff like this: "Now if we multiply Eq. (41.19) by [math], [math]. We want the time average of [math], so let us take the average of the whole equation, and study the three terms. Now what about [math] times the force?" Soo... am I going to need math skills to understand this stuff?

Yes. Calculus was basically invented to solve physics problems.

Great! This part kind of surprises me though: > However, we want to be clear that this edition is only free to read online, and this posting does not transfer any right to download all or any portion of The Feynman Lectures on Physics for any purpose. I know it doesn't actually mean anything in practice, but still, I'm shaking my head in disbelief that there's still people out there clinging to this mentality. Aside…

Lawmakers redefined the meaning of download to "download and permanently store". They don't see "download and only hold in application cache for a limited time" as download.

Does that apply to Susskind's video lectures as well?

So we cannot not scrape this to see how many words are in each chapter, how the technical vocabulary changes over topics, or perform an analysis on connected keywords...

Honestly, I feel that Calc should be taught way earlier, the way that physics is taught in school feels rather incomplete. I mean without calculus, is quite difficult to understand physics.

The Feynman lectures certainly will teach you a lot, but I think it would be a fairly trying textbook for learning a lot of the material for the first time. Among other things, a very serious deficiency for self-education is a complete lack of problems to work (which just reflects that these really were lectures).

Has anyone completed all of the 3 parts? How much time did it take you ?

It's generally a three semester to a full two year sequence at most universities. You can of course go faster or slower depending on your own capacity to self-study and learn, but most bright people will probably fall somewhere in that spread to get a solid grasp of the total contents.

That said, it's always helpful at first to skim through and get a surface understanding of the whole picture before you dive in and try to understand it all. You can probably complete a surface scan like that in a few weeks or months. I studied these becomes along with my high school physics course and completed the books in about a year, but I was spending double the usual amount of time on this stuff. As a high school student, I didn't have anything better to do, but as an adult I'd expect it to take me two dedicated years.

What would you recommend for self-education?
