دانلود کتاب مکانیک کلاسیک بدون چرندیات: مقدمه ای برای دانش آموزان

Classical mechanics is more than 300 years old and dozens, maybe even hundreds, of textbooks on the subject have already been written. So why another one? First of all, this book focuses solely on the fundamental aspects of classical mechanics.1 This narrow focus allows us to discuss.. . all of the important concepts several times from various perspectives. In contrast, most other classical mechanics textbooks try to do a lot at once. For example, it’s not uncommon that in addition to the Newtonian, Lagrangian and Hamiltonian formulations, dozens of applications, edge cases, advanced topics, historical developments or even biographies of the most important contributors are discussed. I think this is problematic because, as the saying goes, if you try to be good at everything, you will not be great at anything. So a clear advantage of the approach used in this book is that the reader has multiple chances to understand a given concept, while in a “normal” textbook the reader immediately has a problem when a passage is not understood perfectly. A second . advantage of our narrow focus is that it minimizes the risk of unnecessarily confusing the reader. Like all other fundamental theories, classical mechanics is, at its heart, quite simple. However, using it to describe complicated systems is far from easy and this is where most of the difficulties usually arise.
