[edit] Hello! And Welcome to my user page.

My name is Gabriel and I am a high school student in Canada.

Sorry if my user page looks poor, but I will give it a different look later when I have time.

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:

It was the "Astronomy Picture of the Day" (APOD) on September 13, 2004.

I also contributed on adding informations about other scientists, such as:

• Einstein, Albert
• Feynman, Richard
• Galilei, Galileo
• Gleiser, Marcelo
• Greene, Brian
• Hubble, Edwin
• Kepler, Johannes
• Lewin, Walter
• Randall, Lisa
• Sagan, Carl
