Time, Einstein, and the Coolest Stuff in the Universe


At the beginning of the twentieth century, Albert Einstein changed the way we think about time. Near the end of the twentieth century scientists learned how to cool a gas of atoms to temperatures billions of times lower than anything else in the universe. 

Now, in the 21st century, Einstein’s thinking and ultracold atoms are shaping the development of atomic clocks, the best timekeepers ever made. Such super-accurate clocks are essential to industry, commerce, and science. They are the heart of the Global Positioning System (GPS) that guides cars, airplanes, and hikers to their destinations. 

Today, the best primary atomic clocks use ultracold atoms, achieve accuracies better than a second in 300 million years, and are getting better all the time. Super-cold atoms, with temperatures that can be below a billionth of a degree above absolute zero, allow tests of some of Einstein’s strangest predictions. 
Join Dr. Phillips for be a lively, multimedia presentation—including experimental demonstrations and down-to-earth explanations about some of today’s most exciting science.

Dr. William D. Phillips is the leader of the Laser Cooling and Trapping Group of the National Institute for Standards and Technology’s Physical Measurement Laboratory—and also a Distinguished University Professor at the University of Maryland. Dr. Phillips’s research group studies the physics of ultracold atomic gases. In 1997, he shared the Nobel Prize in Physics “for development of methods to cool and trap atoms with laser light.”

Physics Teacher Out-Reach Web Meeting 1/14/12! #physicsed #physics #edtech

BrendanNoon The Rochester Area Physics Teacher’s Out Reach (RAPTOR) will hold its first meeting of 2012 at the Rochester Institute of Technology on Saturday, January 14th from 9 am-noon EST.  Physics education enthusiasts all over the world are welcome to attend this meeting live via this link.

The meeting will feature a presentation by Dan Fullerton, author of Regents Physics Essentials, Honors Physics Essentials, and developer of APlusPhysics.com, as well as a presentation and discussion centered around physics lessons addressing New York’s Common Core State Standards and how these changes will affect physics education.

Come for the free donuts and stay for the demos, and if you can’t attend in person, join us online!

Special thanks to Brendan Noon of Science With Mr. Noon for organizing this event.
