4/14 -- Junior Circle: Geometry of masses continued. (Oleg Gleizer)

This time, we will finish the handout on geometry of masses we have started last time. We will use the geometry of masses to get the first proof of the medians theorem and then to generalize it to 3D and 4D. This will take us about an hour. In the second half of the class, we will solve some fun problems not requiring any special knowledge.
