his time, I would like to talk about analytical mechanics. Do you know analytical mechanics? As some of you may have learned when studying quantum mechanics, there are classical mechanics and quantum theory in physics.

Both of these fields reign in the main positions of physics today, and both are disciplines that are deeply ingrained in our lives. Classical theory is a field that deals with very familiar forces such as gravity and mechanics, which is like the foundation of physics established by Newton and Galileo in post-Renaissance Europe. .. However, with the passage of time, its development progressed, and when it came to explaining the phenomenon of electromagnetics, it became clear from the electromagnetic theory summarized by Maxwell and Ampere that a phenomenon that did not fit the classical theory of the past would occur. It was.
