[time-nuts] Shortt Clock Recent Measurements

[Tom Van Baak (lab)]

Brooke,

Not sure what you find in error; please explain.

I have all the Shortt info you need. Not all of it is for Wikipedia; contact me off-line.

Just got back from the CalTech
Time Symposium:

The conjecture about tides is explained in great detail here:
