Though founding quantum electrodynamics is one hell of an achievement, this lecture series is his greatest achievement. If Feynman's approach is not suitable to your palette, then you shouldn't be a physicist--maybe biology or stamp collecting might suit you better. These volumes are not comprehensive, but rather they teach you to think like a physicist.

I'm a little embarrassed that I haven't read all of these yet.

Taught me most of the physics I know and as an electronics engineer I had planty of courses of it.

Probably one of my favorite thinkers, and he has been a favorite topic since he was such a humble, quiet person. Since the first year of the lectures was 1962 I enjoy hearing what the state of science was when I was a year old. Interestingly the lectures remain very relevant today.

Great book with amazing sets of lectures. I love it because he is able to provide great explanations and examples to some of the basic concepts of physics which I could possibly quote during some of my O Level Physics Tuition classes.

I would not try to LEARN physics from this book, but it is a great supplement and occasionally makes one look at a topic from a whole new perspective.

The Feynmans physics course is a non comon undergraduate course because though there are some formulae and math deductions the book is mainly focussed on the explain in deep the fundamental laws and concepts that the in the matemathical expresions,and this are obtaine generally by inductive reasoning,It touches all fundamental subjects,is writen in a very interesting and readable way and sometimes make striking incursions and results that other books dont make,for example from a similar Klein-Gordon relativistic invariant equation for a scalar field,easily obtains by qualitative reasoning the expresión for the Yukava potential for strong interaction scalar meson.A book readable for all with a hig school backgrund and really interested in learn physics,a book that is in physics the twin brother of the renowned book in matemathics by Alexandrov,Kolmogorov and others titled The Matemathics his Methods and Meaning

This is the absolute best physics book(s) ever. If you read the bio's for the US Physics Team, you will regularly find the sharpest high school minds have been inspired by reading Feynman's Lectures. It is inconceivable that one single person, Richard Feynman, can know/understand this amount of material and explain it all so thoroughly. You really need to have taken Physics already prior to diving into these volumes to fully appreciate the clarity that Feynman conveys on these topics.

You can actually see this entire 3-volume series online at https://www.feynmanlectures.caltech.edu/

Feynman has another book called "Six Easy Pieces", which is directly taken from these lectures:
Six Easy Pieces (1994)
Chapters:
Atoms in motion = Lectures Chapter 1
Basic Physics = Lectures Chapter 2
The relation of physics to other sciences = Lectures Chapter 3
Conservation of energy = Lectures Ch 4
The theory of gravitation = Lectures Chapter 7
Quantum behavior = Lectures Chapter 37

Great to just pick up and read anytime. Such insight.
Here is an example from Ch 25, modeling the shock absorber in a car, with an electrical circuit:
From section 25-4: http://www.feynmanlectures.caltech.ed...
"Suppose we have designed an automobile, and want to know how much it is going to shake when it goes over a certain kind of bumpy road. We build an electrical circuit with inductances to represent the inertia of the wheels, spring constants as capacitances to represent the springs of the wheels, and resistors to represent the shock absorbers, and so on for the other parts of the automobile. Then we need a bumpy road. All right, we apply a voltage from a generator, which represents such and such a kind of bump, and then look at how the left wheel jiggles by measuring the charge on some capacitor. Having measured it (it is easy to do), we find that it is bumping too much. Do we need more shock absorber, or less shock absorber? With a complicated thing like an automobile, do we actually change the shock absorber, and solve it all over again? No!, we simply turn a dial; dial number ten is shock absorber number three, so we put in more shock absorber. The bumps are worse—all right, we try less. The bumps are still worse; we change the stiffness of the spring (dial 17), and we adjust all these things electrically, with merely the turn of a knob.

This is called an analog computer. It is a device which imitates the problem that we want to solve by making another problem, which has the same equation, but in another circumstance of nature, and which is easier to build, to measure, to adjust, and to destroy!"

NO other text book does this application-style so well.

After a while, I was lost, but I learned some. Keep learning.

It took me about a year to finish all three volumes, after which I can say I have followed and remembered roughly 20% of Feynman's endless derivations. Nevertheless I have immensely enjoyed every page. I once read an article by an educator who advocated for early teaching of concepts related to infinitesimals and transfinites, exponentiation and concepts related to rate of growth and decline in nature. Her idea was that math and science teachers often follow a chronological order, based on the history of science and the order in which various concepts were discovered and evolved. Instead they should follow a logical order, beginning with "fundamentals" instead of "basics."

To me, Feynman's book wholly represents this idea. The content is organized really well, so it makes it easy to follow the big pictures even if details are getting lost here and there. To anyone who might not have the time to go through all volumes, I highly recommend chapters 1-6, 37-38, and 52 of the first volume, chapters 1-4, 18, and 30 of the second volume, and chapters 1-8 of the third volume.

This book is an experience. And that experience is worth having. Multiple times if you really want to get the most out of it. So I know that I will return to it again and again as I become more mathematically mature and knowledgable of natural science.
