It takes a certain level of knowledge and brilliance which I have yet to attain to get through his stuff. It seems Lev Landau created an entry exam to test his students, and the exam was known to be ridiculously hard.
all other courses by reading various books and original papers.
For a better experience, please enable JavaScript in your browser before proceeding. Also, I think it would make quite a good curriculum of theoretical physics (at least pre 1960).). Today Landau's theoretical minimum (not all 11 exams, but at least 6 of them) is included in the program for students of Department of General and Applied Physics (Moscow Institute of Physics and Technology). site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Contents 1 Lecture 1: Systems and Experiments 1.1 An Experiment In the rst lecture of The Theoretical Minimum: Classical Me-chanics We began by discussing a very simple deterministic system: a coin that can either be … $$, Using the conjugate angular momenta $p_{\theta} = \frac{\partial L}{\partial \dot{\theta}}$ and $p_{\alpha} = \frac{\partial L}{\partial \dot{\alpha}}$, the Euler-Lagrange equations can be written as
The electron falls on the hemisphere, determine the scattering cross section in the Born approximation. My "class" notes and problem solutions.
Theoretical problems with relativistic space flight, The Landau-Zener transition & spin-flipping in an external field. and The sum must not hold true ! I tried to find word in Mount Anthor but it seems that I have read the word, even though I haven't had that word. \frac{d p_{\alpha}}{dt} = \frac{\partial L}{\partial \alpha} = -\dot{\theta}(\dot{\theta}+\dot{\alpha} ) \sin \alpha. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. Can someone please help me with this problem? L = \frac{\dot{\theta}^2}{2} + \frac{\dot{\theta}^2 + JavaScript is disabled. He also mentions some questions in passing, from which I gather most of them were similar to the exercises and examples of his famous books. Further, the book states that there is "conservation of angular momentum", and not "conservation of, Classical Mechanics, The Theoretical Minimum: angular momentum conservation for the double pendulum without gravitational field, Goodbye, Prettify. Is there evidence that the Republican Party leadership wants/prefers fewer people to vote? Exercise 2 . 58 22. Find the time for the electron to fall out (in the semi-classical approximation). Each exam, as it was before, consists of problems solving. The Theoretical Minimum. I wonder if anyone can provide the list of topics, or even a copy of the exam? MathJax reference. Requires either Mathematica 8 or later, or the free Mathematica CDF Viewer, though the viewer cannot run the programs, (you can find that here) Exercise 1 . If you look at the figure at the top of this page, you can easily see that a change in theta would leave the system unchanged, whereas a change in alpha would make a difference. \frac{d}{dt} \frac{\partial L}{\partial \dot{\theta}} = 3\ddot{\theta} + \ddot{\alpha} + (2\ddot{\theta} + \ddot{\alpha})\cos \alpha - For What happens when I encrypt something with my RSA Public Key? This will include hints and detailed solutions to the practice problems and additional materials that did not fit, or could not be used in the book. this means that only the conjugate momentum for Ptheta is conserved (which btw contains theta and alpha). $$ You might try reading his books for the problems as per this physics stackexchange discussion: Any Lev problem is worthy of solving. Why can so little digital information be stored on a cassette tape? Conservation of the total angular momentum implies that \frac{d}{dt} \frac{\partial L}{\partial \dot{\alpha}} = \ddot{\theta} + \ddot{\alpha} + \ddot{\theta}\cos \alpha - \dot{\alpha} \dot{\theta} \sin \alpha. They were all so difficult and I didn't have the patience to solve them or if I did I'd get stuck and couldn't prove my answer was correct. For every exam there is one or several examiners with whom you are supposed to contact with to inform that you're willing to pass this particular exam (they will make an appointment). Hello highlight.js! Why isn't Landau credited as an author in Vol 4? Why? The lower end of the plastic bag is cut with scissors. The tube is bent at a radius $R \gg r$ by the angle $\alpha$ and then is aligned back again. …

I found this the best intro course ever for QM. Quantum-Mechanics---The-Theoretical-Minimum. Moscow Institute of Physics and Technology, Goodbye, Prettify. "Dee-twenty" and "die-twenty" pronunciations. the first (classical) part of Statistical Physics. and
Hello highlight.js! Nowadays students are examined by collaborators of Landau Institute for Theoretical Physics. How do I identify and replace unusual screws? $\frac{d}{dt} \big[ p_{\theta} + p_{\alpha}\big] = 0$ Why isn’t the third person singular used in “The Lord bless you”? (Should it be? $$ What are the effects of sugar in cat food? Fat advanced textbooks are not suitable to people who have no teacher to ask questions of, and the popular literature does not go deeply enough … Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. From this expression it can be seen that $\frac{\partial L}{\partial \theta}=0$ and $\frac{\partial L}{\partial \alpha} = -\dot{\theta}(\dot{\theta}+\dot{\alpha} ) \sin \alpha$.
$$ $$ \dot{\alpha}(2\dot{\theta} + \dot{\alpha}) \sin \alpha = 0, $$ 3\ddot{\theta} + \ddot{\alpha} + (2\ddot{\theta} + \ddot{\alpha})\cos \alpha - Should I complain to higher authorities about the incompetence of this teacher? and Black Lion opening plans for White 5.Bc4 line.
\frac{d}{dt} \big[ p_{\theta} + p_{\alpha}\big] = -\dot{\theta}(\dot{\theta}+\dot{\alpha} ) \sin \alpha. Mechanics, Classical Field Theory, The Theory of Continuous Media and A world-class physicist and a citizen scientist combine forces to teach Physics 101—the DIY way. The electron enters a straight pipe of circular cross section (radius $r$). Hydrogen embrittlement creates complications for clean energy storage, transportation, The discovery of triplet spin superconductivity in diamonds, A protocol to minimize the thermodynamic cost of erasing a single bit over a given amount of time, http://physics.stackexchange.com/questions/13861/lev-landaus-theoretical-minimum, Question about minimum operating temperature for a theoretical brayton cycle engine, A thermodynamic inequality (from minimum work). I got an offer from my dream graduate school days after starting grad school somewhere else.
