# 4/21 -- Junior Circle: A few funny problems. (Oleg Gleizer)

We will finish our first encounter with the geometry of masses by finally proving the medians theorem in 2D. We will further generalize it to 3D and 4D. To take a break from studying theoretical stuff, we will further solve a bunch of problems that require no special knowledge, but are a lot of fun! If time remains, we will switch back to theory and approach the median theorem from a different direction. It will be linear algebra this time.
