Hello! And Welcome to my user page.

I am very interested in mathematics and science, specially physics and astronomy, so basically I am interested mostly in scientific wikipedia articles and articles about famous scientists.

The Following links are wiki articles I created as a contribution to Wikipedia and the world:

• Walter Lewin Lectures on Physics

Here are some pictures I updated to Wikipedia:

Walter Lewin, MIT Professor of Physics:

• Lewin demonstrating that the period of a pendulum is independent of the mass hanging from the pendulum.

• Hubble, Edwin
• Kepler, Johannes
• Lewin, Walter
• Randall, Lisa
• Sagan, Carl
