Quantum Mechanics is

HARD

Quantum Mechanics

Lab!

Quantum Mechanics is

BIG But we’ll focus on a small piece

Let’s Start With Something simple

Where is Mr. Hall?

Sum  over  Histories  

Again, Quantum Mechanics is

Weird But,

It makes useful predictions about our world

Protein  Folding  

By combining quantum and classical physics,Levitt’s and Warshel’s Model dramatically sped up the

calculations, while still remaining accurate

LAB!!!  But first, just a little more background

Procedure  

1.  Shine  laser  at  blank  surface,  postulate  what  spliBng  the  beam  will  do  

2.  Glue  a  wire  to  the  laser,  bisecEng  it  in  half  3.  Measure  spacing  of  bands  4.  Determine  the  wavelength  of  the  laser,  using  

the  formula  w=z*lambda/d  

How this ties in
