Slider crank mechanism with satellite pulley
The diameter of the big pulley is double the one of the green pulley. The length of each crank = R The slider's stroke = 4R The belt should be toothed. It is possible to use chain drive instead of belt one. STEP files of this video: http://www.mediafire.com/file/frn0cmys8sedruy/SliderCrank

In this video, I define the concept of a winding number of a curve around a point, which intuitively measures how many times a curve loops around a point. For example, for a circle (or any simple closed curve), the winding number should be 1, but for the curve in the thumbnail, the winding

B. Weiss - Horocycle dynamics (Part 1)
A major challenge in dynamics on moduli spaces is to understand the behavior of the horocycle flow. We will motivate this problem and discuss what is known and what is not known about it, focusing on the genus 2 case. Specific topics to be covered include: * SL_2(R) orbit closures and inva
