Paper Introduction:
STEVEN CHU: NOBEL LAUREATE
The Nobel Prize is perhaps the most coveted recognition of excellence in a given field. In 1997, the Nobel Prize in Physics was given to Professor Steven Chu of Stanford University along with two of his colleagues, William D. Phillips and Claude Cohen-Tannoudji. The contributions of these three men mounted over the span of more than a decade of research and experimentation, culminating in the development of groundbreaking new methods to cool and trap atoms with laser light.
Steven Chu has been an avid Physics enthusiast ever since his high school days in Garden City, New York, where under the tutelage of his Advanced Placement Physics teacher he was given his first taste of genuine lab experience(College Board Online, 1998). In the year
