Discussion of the release of GP-B Final Results

Discussion of the release of GP-B Final Results

Discussion of GP-B -- for the last time?!

As some of our members may remember, we discussed the Gravity Probe B several times back in 2005, 2006, and 2007.  Data from this experiment was initially released in April 2007 -- a widely anticipated event.  Our last full discussion of the GP-B was back in April 2007; full results were expected by autumn 2007, then spring 2008, then ... ANYWAY, is anyone else eager to discuss the final results?!  Will this be our final meetup with this topic?!

So, four years have passed since the release of the initial results, and unfortunately, our most interested member is not here to review the results.  Our beloved former member, Dr. Russ Collins, who passed away in October 2010 and who was an active member of our physics/science meetup, attended the American Physical Society (APS) meeting in Jacksonville, Florida, at which the GP-B results were released.  He was very knowledgeable about this experiment and had his own unique ideas about relativity and the expected results from the GP-B.  A portion of our discussion will include a review of Dr. Collins's prediction of the GP-B results. 

For the purposes of advancing the meeting's discussion, everyone should already be familiar with the basic goals of the experiment and the basic construction and operation of the satellite.  If you are not already familiar with the GP-B, these are great sites:

I will post the email notices that I received last month into the meetup message board and the final results files into the meetup files.

    Good to meet Joe and Cliff. The meeting was fun, we had a great discussion of the Gravity satellite and several associated subjects. The library room worked well, room for 50 people, but mainly quiet and we were able to talk.

I'm surprised by the level of growth I've seen since becoming an organizer, it's given me more confidence in my abilities.
