Stephen Chu was born on February 28, 1948 in St. Louis, Missouri. He attended University of Rochester in New York during 1970 where he received both a Bachelor of Arts degree in mathematics and a Bachelor of Science degree in physics. He also received his Ph.D. in physics from the University of California, Berkeley, in 1976. His field of study is physics. Steven Chu’s early research was on atomic physics and developing laser cooling techniques and the trapping of atoms using lasers. Chu developed a technique called trapping atoms which allows scientists to study atoms very accurately. Chu’s method can be used to construct and atomic clock which is used in highly radioactive areas. Chu also did research in the field of biological physics. He studied enzyme activity and protein and RNA and formed techniques such as fluorescence resonance energy transfer, atomic force microscopy and optical tweezers, which a lot of scientists use today in their research. Chu has also been an advocate to prevent global warning and has come up with many theories to stop global warming such as having white or bright colored roof-tops. In 1997, Steven Chu, along with his partners: Claude Cohen-Tannoudji and William Daniel Phillips, won the Nobel Prize in Physics for the “development of methods to cool and trap atoms with laser light. In 1995, he was also rewarded the Humboldt Prize by the Alexander von Humboldt Foundation. In August 2004, Chu was appointed as the director of the Lawrence Berkeley National Laboratory. Chu also has many other interests besides his scientific career, such as baseball, swimming and cycling. In the eighth grade, he taught himself tennis by reading a book. On January 21, 2009, Steven Chu was nominated as the Secretary of Energy by the U.S Senate and was elected as a member of the US Cabinet. I picked this scientist because he is a male and also comes from a family of immigrants such as myself. Steven Chu encourages me...
