Math in movies: Dr Zhivago Scene

The classic movie Dr Zhivago features a tiny bit of math. The scene is just a few seconds before Yuri sees Lara the first time. The moments when Lara is close is always accompanied by the sound of the Balalaika. 

The movie has grown to one of the greatest of all times. It was one of the first movies I myself have seen in a movie theatre (as a kid) and had been affected a lot by the scene in which Yuri would see Lara the last time falling dead onto the street without her noticing.
