Warren, No, measuring an oscillator every second will not help.
The change in g = ~9.81 m/s due to tides is about 1e-7 over part of a day. So g changes by about 1e-8 per hour; that's about 1e-12 per second. Now df/dg for a 10811 is on the order of 1e-9. So the tidal effect of the sun/moon will change a 10811's frequency by about 1e-12 x 1e-9 = 1e-21 per second, which is about a billion times below the short-term noise level of a 10811. Now the reason pendulum clocks can "detect" tides (and only a few of the world's best have ever done so) is that their frequency is directly dependent on g. That is, df/dg for a pendulum clock is 0.5! By contrast df/dg for a 10811 quartz oscillator is around 0.000000001. /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
