Beautiful Science and Engineering

this is a public page for every one who is interested in Science from any place from our EARTH. Any link or any website about Science will be appreciated.

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.
