Learn Lagrangian & Hamiltonian Mechanics without Calculus of Variations

AI Thread Summary
Lagrangian and Hamiltonian mechanics can be understood without mastering calculus of variations, appealing to those with a background in elementary calculus and Newtonian mechanics. Resources like Susskind's video lectures on classical mechanics provide accessible insights into these topics, similar to popular science treatments. The discussion emphasizes the desire for an overview rather than a traditional textbook approach. Participants express interest in materials that simplify complex concepts for a broader audience. Overall, there are alternative learning resources available that cater to non-experts in the field.

Does anyone know of a treatment of Lagrangian and/or Hamiltonian mechanics that would be accessible to someone who is (or was, about forty years ago) reasonably fluent in elementary calculus and Newtonian mechanics? I am less interested in a college textbook than in an overview a la Brian Greene on String Theory or Bruce A. Schumm on particle physics. Is there a level of understanding to be had short of mastering the calculus of variations?

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
