William Daniel Phillips is a famous American physicist. He was born on November 5, 1948, in Wilkes-Barre, Pennsylvania. His father was from Welsh descent and his mother was of Italian descent. He grew up in Camp Hill, near Harrisburg, Pennsylvania. Phillips was a very bright student in school. He graduated as the valedictorian of his high school class in 1966. Later, he graduated from Juniata College in 1970 with high honors. He then earned his physics doctorate from the Massachusetts Institute of Technology.

Phillips is best known for his work with laser cooling. This is a special way to slow down moving atoms. Atoms are tiny bits that make up everything in our world. When atoms move very fast, they are hard to study. He invented a tool called a Zeeman slower to help this work. This tool helps scientists control the movement of gaseous atoms. By slowing them down, scientists can study them much better. This work helped lead to the study of Bose–Einstein condensates.

His hard work earned him the highest honors in science. In 1997, he won the Nobel Prize in Physics. He shared this prize with Steven Chu and Claude Cohen-Tannoudji. This award was for his contributions to laser cooling. He also received the Albert A. Michelson Medal in 1996. Other awards include the Arthur L. Schawlow Prize in Laser Science. He has been elected to many important groups like the National Academy of Sciences.

Phillips has spent many years working at important science places. In 1978, he joined the National Bureau of Standards. This place is now known as NIST. He also works as a professor at the University of Maryland. He teaches at the University of Maryland, College Park. Phillips also helps guide science festivals for students. In 2010, he had lunch with middle and high school students. He wanted to talk to them about being a scientist.

Beyond his lab work, Phillips cares about the world. He has signed letters to leaders like President George W. Bush. He asked for more money to support basic science research. He also signed a letter to President Obama about clean energy. Phillips is interested in how science and religion work together. He is a member of the International Society for Science and Religion. He and his wife, Jane, have two daughters. One daughter, Caitlin, started a business called Rebound Designs. His other daughter, Christine, works in science communication.
