The "Theorical Minimum" was the name of the exam that applicants had to pass in order to enter the theoretical physics department of the Kharkov Physicotechnical Institute headed by Lev Davidovich Landau. L. D. Landau, along with A.I. Kitaigorodskii, is also known to have written a serie of four great popular science books presenting general physics to young people, "Physics for everyone" (which happens to be the name of Leonard Susskind's blog too...). I'm wondering if "The Theoretical Minimum: what you need to know to start doing physics" couldn't be the first book of a follow-up to "Physics for everyone".
I've studied physics in university but I've stopped before starting working on a PhD. That was more than ten years ago and I needed to earn a living but I still loved science especially physics. One day I've discovered the Leonard Susskind's Theoretical Minimum courses on Youtube and Itunes and I was litterally astonished by them as they are exactly what I was looking for: not courses for advanced undergraduate students, not popular science presentations devoid of any technicity (theoretical physics without maths is an empty shell: theoretical physics is about creating mathematical models of the physical world) but courses for people like me who knew some maths and physics at one point of their life and that want to learn the concepts of theoretical physics. Each course is made of about ten lectures, each lectures lasting about two hours. Watching these is quite time consuming and time is sparse if you have a job and a family. Also the courses were sometimes a little sketchy or not quite well organized (especially the first run... the second run is a lot better). The material simply had to be reworked and layed out on paper. George Hrabovsky felt these were necessary too so he contacted Leonard Susskind and voila, we now have a book, the first of a whole serie, the one about classical mechanics.
I knew about some of the material in the book. In the quantum mechanics (QM) courses I followed I learned about least-action principle, Lagrangians, Hamiltonians (fundamental in QM) and Poisson brackets (their siblings, commutators, are also fundamental in QM). The problem is that these notions and their purpose didn't make sense to me. I wasn't told or I didn't have time to realize their conceptual power and that they could be used in classical mechanics: use of Lagrangian formalism to understand the double pendulum, use of Poisson brackets to determine the behavior of a charged rotor in a magnetic field. Also I wasn't told about Noether's theorem (relationship between symmetries and conserved quantities), Liouville's theorem (well perhaps in statistical mechanics... I'm not sure) or the importance of gauge fields (vector potential field is one) but that may be because I wasn't taught to be a theoricist. Here Leonard Susskind's a guide who shows us the elegance of all these concepts and prepares us to a voyage to quantum physics and field theories.The book shows the coherence of these concepts, it structures the reader's mind (if he makes the proper efforts by doing the exercises: doing exercises are necessary to learn and understand). George Hrabovsky brought us a great contribution by making the text more accessible (in the videos the student is assumed to know about calculus and general physics) and whipping out ambiguities. The book isn't entirely self-contained though (for example total differentials or Taylor series are used without these notions being introduced... just search "Taylor series" and "total derivative" in Wikipedia) but George will provide some support to the reader in his web site.
Theoretical Minimum - Classical Mechanics isn't another popular science book. It's a book that you'll have to work through a bit but it's a book that will structure your perception of our physical world. This book is the first of a serie that could become somehow the theoretical physics equivalent of Feynman's Lectures. You won't become a theorical physicist just by working through this book and the ones that will follow (have a look at a Quantum Field Theory textbook and you'll see). However if you are interested in physics (not only theoretical) the book will tell you about the concepts used in physics, how physicists manipulate them, how physicists do math and what makes physicists tick.
I really hope that this book will be translated in many languages.
