What type of details about francis everitt can be gathered from the following bio? Bio: c. w. francis everitt is a us-based english physicist working on experimental testing of general relativity . everitt was educated at imperial college london and the university of pennsylvania in low-temperature physics . he is professor at the hansen experimental physics laboratory of stanford university and is also an associate member of the kavli institute for particle astrophysics and cosmology -lrb- kipac -rrb- . everitt is principal investigator of the gravity probe b mission mainly aimed to test frame-dragging at an expected accuracy of 1 % . according to general relativity , it is an effect induced by the rotation of the earth on orbiting gyroscopes . everitt spent more than 40 years on the project and was awarded with the nasa distinguished public service medal . the results were published in physical review letters in may 2011 . the results confirm general relativity 's predictions , though not to the project 's ambitious goal of 1 % precision . besides , it is very hard to reproduce the measurement results by another independent institution for the scientific world to achieve the consensus . however , the technologies developed via gp-b program benefit experimental physical sciences in many ways .
