Do you have some kind of personal attitude to the Landsberg textbook, is it worth it to send it to the landing dump, or is it really good and it should be modernized?

To be honest, I don’t remember what textbooks I studied. I know, of course, that in my time the Landsberg course was in hearing, but I don’t know how the current generation will perceive it. Of course, there are long-lived textbooks, especially in mathematics (it is enough to recall Kiselev’s algebra), however, five volumes of Sivukhin, Feynman lectures on physics, the same Orir, and also Cooper, textbooks for US Colleges, etc. have appeared.
Of course, the Landsberg course was one of the first, but there was also Frish and Kitaygorod, so students' preferences were largely dependent on teachers, and not on the quality of textbooks. I think that even now the Landsberg course will have its own audience, especially if there is an enthusiast that can “modernize” it.

I believe that the written by V. Svishchenko is quite reasonable. I just don’t know who would now be able to fulfill the program for updating examples proposed by him. Maybe there is such a person. If only it did not work out that some kind of boobs of considerations that are not related to science will do this.

At school, I loved Landsberg very much, because I lacked an ordinary textbook. But here, in the USA, we use other textbooks, also very good and modern. Without Landsberg in his hands, it is difficult to compare and think about modernization.

I do not remember the Landsberg textbook on general physics very well. But I recall his optics textbook, which used when he was a student. I think that the biggest impact on me as a physicist had: “The Course of Theoretical Physics Landau and Lifshits” and “Feynman lectures in physics” edited by R. Feynman, R. Leighton (Rb Leighton) and M. Sands (M. Sands).
