ESP Biography
ALEX WANG, Cornell sophomore studying physics
Major: Physics, Computer Science College/Employer: Cornell Year of Graduation: 2018 

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. Past Classes(Look at the class archive for more.)Lagrangians Mechanics for Young Physicists in Splash Spring 2016
In this class you will learn an entirely new formulation of mechanics called Lagrangian mechanics.
Instead of drawing freebody diagrams and finding the net forces acting on a body (Newtonian mechanics),
we will take a higherlevel 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 higherlevel physics such as quantum
mechanics and field theories which I will briefly mention at the end of the class.
