my professional career can be summarized in that I'm a man who's rich in ambition and challenge. I find ultimate joy in helping others succeed, reach their full potentials and feel good about themselves. for this reason, i created a Facebook page ( Geology of the World and the Environment www.Facebook.com/GeologyHere.Environment ) to help geologists around the world by adding a lot of posts on geology and earth sciences , my page currently has reached more than 200,000 followers, also i offer private lessons in mathematics and physics for high school (it's 11 year of experience).
