Where does formula (7) come from, and what does it mean? Why is (8) valid? Sorry. I forgot to number the equations. Equation 7 is the second-to-last one. Equation 8 is the last one. That’s how they are numbered in the book

Yes, that correct

In the book Lectures on Quantum Mechanics by L.D. Faddeev and O.A. Yakubovskii the authors write the following: Among the observables there may be some that are functionally dependent, and hence it is necessary to impose a condition on the probability distributions of such observables. If an...

Yes, that's right. Should I write to another forum topic?

In the attached image, there is a passage from the textbook Faddeev, L.D., Yakubovskii, O.A. — Lectures on Quantum Mechanics for Mathematics Students, and I have the following two questions: 1) It is clear what it means to specify the conditions of an experiment in classical mechanics so that...

Is the following understanding correct? We are considering such spacetime transformations — symmetries — under which the laws of physics remain unchanged. For example, if space is homogeneous, time is homogeneous, and space is isotropic, then the corresponding symmetry transformations are...

Here is an excerpt from a lecture by my teacher Emil Akhmedov (MIPT) And I have the following question. It turns out that the probability wave describing a free particle is determined by its energy and momentum, right? But what do these two words—energy and momentum—actually mean in quantum...

Hi everyone! My name is Vitaly, and I’m a third-year student at MIPT (Moscow Institute of Physics and Technology), studying at the Faculty of General and Applied Physics, in the department of Mathematical Methods of Modern Physics, which is headed by Roman Nikolaevich Karasev. I truly became...
