Brief Biographical Sketch:

From a small town known as Potsdam, NY, Alex is currently a sophomore studying physics at Cornelll University. He is fascinated with physical phenomena and the unreasonable effectiveness of our mathematics in describing the universe. When he's not working on his classes, he enjoys playing badminton and tennis recreationally.

P231: Lagrangians Mechanics for Young Physicists in Splash Spring 2016 (Apr. 23, 2016)
In this class you will learn an entirely new formulation of mechanics called Lagrangian mechanics. Instead of drawing free-body diagrams and finding the net forces acting on a body (Newtonian mechanics), we will take a higher-level approach by finding the infinite dimensional saddle point of a quantity called the action which is the integral of a function called the Lagrangian. From there, we can derive the equations of motions of an object often with much less effort than if we used Newtonian mechanics! It turns out that this approach can be extended to higher-level physics such as quantum mechanics and field theories which I will briefly mention at the end of the class.
