President Obama on the Necessity of Science (video)

Submitted by Teng Li on

Obama spoke at the National Academy of Sciences on Apr. 27, 2009, in which he states his commitment to doubling of science funding and stem education. From his speech,

 "At such a difficult moment, there are those who say we cannot afford to invest in science, that support for research is somehow a luxury at moments defined by necessities.  I fundamentally disagree.  Science is more essential for our prosperity, our security, our health, our environment and our quality of life than it has ever been before."

Einstein's birthday, the PI day

Submitted by Pi-Gang Luan on

The day before yesterday, Mar. 14 (3.14), was a great date, because Albert Einstein was born at the same day 130 years ago.

I and my wife enjoyed a very good holiday that day in Taipei. Most interestingly, we found a vivid statue of Einstein made by Ju Ming, stood still in front of the Chen-Ping (eslite) bookstore.

We took several photos around this statue. Here I share one of them with you.

This is my first 2009 article

Now I come here again.

From now on I want to share with you my research experiences and personal opinion on  time dependent quantum system, photonic/sonic crystals, and metamaterials.  I would also like to write some articles on science teaching stuff.

I come from Taiwan. Usually I speak chinese, and have no many oppernituties to practice my English, so I wish someone can help me to improve my English. Thanks !
