Talk:Odd sympathy

Too much emphasis on Georgia State experiment? edit

The article gives undue weight to the Georgia State experiments, implying that the cause of sympathetic vibration was only confirmed by them in 2002. In actuality the phenomenon of synchronization of pendulums coupled through their mountings was analysed thoroughly by 19th century scientists. Clockmakers of the time knew not to mount pendulum clocks on the same wall. The errors caused in gravimeter pendulums by the microscopic swaying of their mounts were analysed in the 1880s with the Michelson interferometer. The double pendulum gravimeter, which cancelled these errors by using two pendulums on the same suspension, swinging 180 degrees out of phase, was invented by Herve Faye around the 1880s, and was used from the turn of the century until the 1930s. Coupled pendulums were also considered for timekeeping, and several scientists built experimental coupled pendulum clocks. This subject has a long history, and almost none of it is included in this article. --ChetvornoTALK 23:13, 19 December 2009 (UTC)Reply

Merge this article? edit

As far as I can tell, the phrase odd sympathy has absolutely no currency today for describing coupled oscillations, and may never have had much usage outside Huygens 1665 writings. I googled it and came up with almost no hits relating to physics. The closest term used today is sympathetic vibration which refers to a broader phenomenon. I'd suggest merging this article into Oscillation, Sympathetic resonance, Normal mode, or a new Coupled oscillation article. --ChetvornoTALK 01:01, 29 December 2009 (UTC)Reply

Merged article into Pendulum

Redirect target edit

After the merge, this article redirects to pendulum where the phrase odd sympathy doesn't appear at all making it rather confusing. It should either redirect to a specific section (Pendulum#Coupled pendulums?) or to injection locking which I think is more appropriate in current state of these articles. —MwGamera (talk) 04:52, 31 December 2019 (UTC)Reply

I redirected it to Pendulum#Coupled pendulums, as I feel that is more directly relevant than Injection locking which is a much broader topic which doesn't necessarily involve two coupled harmonic oscillators. --ChetvornoTALK 21:08, 31 December 2019 (UTC)Reply
