| 21. | The Foucault pendulum is an example from classical mechanics that is sometimes used to illustrate the geometric phase.
|
| 22. | When a Foucault pendulum is suspended at the equator, the plane of oscillation remains fixed relative to Earth.
|
| 23. | The first instruments of the observatory were a 15-cm Unitron telescope, a Foucault pendulum and an Iris photometer.
|
| 24. | :You mean like a Foucault pendulum?
|
| 25. | Spin of a relativistic particle moving in a circular orbit precesses similar to the swing plane of Foucault pendulum.
|
| 26. | At this rate a Foucault pendulum would have to oscillate for more than 16000 years to precess 1 degree.
|
| 27. | In the former church of St-Martin-des-Champs Priory are displayed cars, planes, the Foucault Pendulum and some other monumental objects.
|
| 28. | On April 12, 1931, the first public demonstration of the Foucault pendulum was held to visualize Copernicus s theory.
|
| 29. | A Foucault pendulum requires care to set up because imprecise construction can cause additional veering which masks the terrestrial effect.
