Talk:Kater's pendulum

It would be nice to have a picture of one. Besselfunctions 21:43, 28 November 2005 (UTC)

Excellent Explanation, Dates
I've only read it quickly, but the explanation of the pendulum is excellent. Only suggestion I have is minor: dates in the "Kater's solution" section. JKeck (talk) 02:15, 3 December 2011 (UTC)

Good read, but...
In the section "Repsold–Bessel pendulum" the sentence "Here h1, and h2, are the distances of the two pivots from the pendulum's center of gravity, so h1 + h2 = L,..." is a bit confusing to me. The two pivot points are by definition not the real conjugate pivot points (at least not at all locations on the earth), so the sum of their distances from the CG is not the length from any one of the pivot point to its corresponding center of oscillation, i.e. L as defined in the preceding text.

Am I missing something here?

 * I wrote that. You're right, h1 + h2 is not equal to L.  I don't know where I got that.     I've corrected the text, see if you think it is accurate now.   Thank you so much for catching that screwup, Tony Ho. -- Chetvorno TALK 13:58, 22 September 2014 (UTC)
