With physical oscillators coupling is limited by the speed of sound (in the medium, with pendulum clocks wood is lots quicker than air with 3-4 km/s) with electronic oscillators the speed of light. Latter means that their distance has to be short enough so that they lie within each other's lightcone within roughly the period of oscillation orelse they couldn't possibly causally influence each other. At THz half light cone is some 0.3 mm, GHz is about 0.3 m, MHz 300 m, kHz 300 km. -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE _______________________________________________ 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.
