Innovations from Gravity Probe B have fed directly ray ban saleinto improvements in the Global Positioning System (GPS). And a Nasa mission called Cobe that pictured the Universe less than a million years after the Big Bang owed its success to technology ray ban aviator sunglassesdeveloped on Gravity Probe B.

Unending tests

Some 100 students achieved their PhDs by working on some aspect of the mission during the many years it took to develop,ray ban wayfarer sunglasses build and then fly the probe.

Most of these PhDs were earned at Stanford, and at the universities in Huntsville; and in Aberdeen,oakley sunglasses UK. More than 350 undergraduate students also worked on GP-B, including one who later became the first female American astronaut in space, Sally Ride. Another was Eric Cornell, who won the Nobel Prize in Physics in 2001.

"The precession of a gyroscope in afake oakley sunglasses gravitational field of a rotating body has never been measured before today. While the result in this case does support Einstein, it didn't have to," commented Professor Clifford Will fromoakley sunglasses sale Washington University, St. Louis.
