On Friday Jan 20 and during the next Friday we will begin to talk about problems related to spring and masses systems.

The first one will be a question of how can we weight an object in a room having only a spring and a photo camera with us. We will discuss the basic physical model for the problem, possible math formulation, and brainstorm about solutions. We will discuss feasibility of the model and extensions to more realistic models. Then we will attempt to confirm our result through numerical simulations.

Extensions for summer projects in this area will be presented.
