Hey guys, today I would like to share a cool video with you. This youtube video is all about unsolved mathematical problems, which can be understood even by school children. The interesting thing is that MathPickle and The Pacific Institute for the Mathematical Sciences are offering a prize of 1 million dollars for the person, who solved any of the 13 unsolved problems and his/hers most inspirational teacher. So check out this cool video and don’t forget to visit MathPickle, which is an amazing website for both students and teachers. Also, for more updates from Physics Database don’t forget to register at the website for updates via email or simply follow/like us on Facebook. Cheers.
