You can share us by any beautiful video about Science and Engineering. I made this group from here (EGYPT) especially after our revolution as we hope all that Egypt will find it's way to improve it's education and scientific research. i wish this group will help anyone who is interested from......students, teachers, Doctors, Engineers, and even beginners :) I hope you all like it. LET'S START WITH
