The edges of the black cotton are frayed slightly. Using a copper ring underneath each orb to damp down the drift, Salva was able to easily observe and measure precession, the technical name for the movement of the Earth relative to the fixed swinging of the pendulums. http://rsi.aip.org/resource/1/rsinak/v81/i11/p115102_s1?view=fulltext&bypassSSO=1, Quote from: Tausami on March 13, 2012, 12:21:24 PM, Re: DIY Foucault Pendulum Published Article -- The Earth Rotates, Quote from: Pope Zera on November 17, 2010, 08:03:29 PM, http://www.theflatearthsociety.org/tiki/tiki-index.php?page=Foucault+Pendulum, Quote from: Tom Bishop on November 18, 2010, 09:46:16 AM, Quote from: ClockTower on November 18, 2010, 09:54:58 AM, Quote from: Tom Bishop on November 18, 2010, 11:09:38 AM, Quote from: ClockTower on November 18, 2010, 11:13:45 AM, Quote from: Tom Bishop on November 18, 2010, 12:31:46 PM, Quote from: ClockTower on November 18, 2010, 12:37:34 PM, Quote from: gotham on November 18, 2010, 01:33:29 PM, Quote from: ClockTower on November 18, 2010, 01:39:46 PM, Quote from: gotham on November 18, 2010, 01:42:42 PM, http://thulescientific.com/Lynch%20Curvature%202008.pdf, http://thulescientific.com/TurbulentShipWakes_Lynch_AO_2005.pdf, Quote from: gotham on November 18, 2010, 01:54:49 PM, Quote from: Tom Bishop on November 18, 2010, 02:17:19 PM, Quote from: ClockTower on November 18, 2010, 02:19:41 PM, Quote from: Tom Bishop on November 18, 2010, 03:53:17 PM, Quote from: Tom Bishop on November 18, 2010, 08:21:24 PM.

Test the pencil by flicking it with your finger. This way, it can traverse the remaining distance in less time than the lower pendulum, and it works just right so that they arrive in the neutral position at the same time. That's bad news if you want to build a Foucalt Pendulum, a bob attached to a long wire swinging in a vertical plane that appears to rotate as the Earth spins beneath it. Let the pendulum fall on its own; don’t swing or push it. © 2002-2018 redOrbit.com. :D. That sounds like a feat of engineering, not science. Or rather, it’s more accurate to say that pendulums swing in a mostly fixed plane. When you release the pendulum, count the number of oscillations, or the number of times it swings back and forth, for 1 minute. I don't think Illuminatus! Comments owned by the poster.

By definition, Foucault pendulums — which are named after the French physicist L©on Foucault who first conceived of one in the middle of the 19th century — count as a simple technology. It works like retrophrenology (diskworld reference). The new insight is that if the pushing pulse is delayed to the right point in the cycle, the applied force dampens, rather than increases, the tendency for the oscillation to become ellipical.
