MIT Public Class 6002: Electrical Circuit & Electronics I believe most Chinese engineering students have seen a heating PBS drama "The Big Bang Theory". The cute Indian nerd Rajesh who always speaks with a strong accent is very popular among Chinese students in the show. However, when there is no subtitle, I found it quite hard to understand any single word with an Indian accent. Recently, I am working on the MIT public class series; an Indian professor, passionate, logical, and facetious, turns to speak in a way I shall never follow. The strong accent just drived me crazy! Because only a few of his classes are subtitled, I forced myself to try my best to understand what he says without the help of subtitles. The result is quite amazing. Today, I watched one of his original class which has no tranlation; It is about operational amplifier analysis and I think I caught every single point that matters. I think that marks a giant leap for me, like evolution or chromosome mutation!

America: The Story of Us It is an amazing documentary. Why America developed into a superpower in less than 300 years? After watching this documentary, I have my own point of view. First, the geography advantage. America is far from Eurasia continent; the major battlefields of The Second World War are far away from the mainland of America, so the economy and infrastructure in America are not jeopardized during the war. Besides, Vast territory and sporadic native american tribes ruling on it mean it is very easy for the decedants of Mayflower to take over the power of sovereignty. Additionally, the Mississippi and Missouri rivers are north-south, different from Yangzi and Yellow rivers in China which are east-west. Different latitude means different resources, and Missouri and Mississippi are the best means of transportaion. Last but not least, America is a miracle land with vast amount of natural resources. Threre are limber in Michigan, coal in Colorado, crude oil in Texas, and gold in California. All raw materials to develop industry and mass production can be found in this country. What a sweet miracle given by god! Second and third reason is under production.

Please recommend some documentary film about America! Thanks. I really want to know more about this country. Lately, I watched a documentary called America: The Story of Us. It is amazing. Could you please recommend some other documentary for me? Geography, religion, landscapes, economy, law, systems and networks, science and technology, sociology, history...All things about this country is OK! Thank you!
