Hi Tom:
The way I read the comment about detecting the influence of the Moon was that it was discovered in 1984, but I was under
the impression that Loomis found it long before.
I looked on other Wiki pages and did not see on any of the them information about Loomis and the effect of the Moon on
pendulum clocks.
Have Fun,

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

The conjecture about tides is explained in great detail here:

Hi:
The Wiki page for the Shortt pendulum clock has a "Recent Measurements" (1984)
paragraph that's in error.
http://en.wikipedia.org/wiki/Shortt-Synchronome_clock#Recent_accuracy_measurement
While it's probably true that the clock is stable to 200 uS per day (i.e. 2E-9)
I believe Alfred Loomis discovered the effect of the moon on this clock a long
time ago.
Is there a link to his paper at the Royal Society on that topic that could be
added to the Wiki page?
