The perch is an equilibristic balancing act where one performer balances atop a pole that is being balanced by another performer. Each perch pole has a loop at the top into which the performer may insert either a hand or a foot in order to perform a variety of tricks while hanging down from the loop.
A much more accurate experiment using a torsion balance was carried out by Loránd Eötvös starting around 1885, with further improvements in a lengthy run between 1906 and 1909. Eötvös's team followed this with a series of similar but more accurate experiments, as well as experiments with different types of materials and in different ...
PhET Interactive Simulations is part of the University of Colorado Boulder which is a member of the Association of American Universities. [10] The team changes over time and has about 16 members consisting of professors, post-doctoral students, researchers, education specialists, software engineers (sometimes contractors), educators, and administrative assistants.

The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation. If a long and heavy pendulum suspended from the high roof above a circular area is monitored over an extended period of time, its plane of oscillation appears to change ...
The balancing of rotating bodies is important to avoid vibration. In heavy industrial machines such as gas turbines and electric generators, vibration can cause catastrophic failure, as well as noise and discomfort. In the case of a narrow wheel, balancing simply involves moving the center of gravity to the centre of rotation
A woman in Germany was sentenced to life in prison for murdering her "doppelgänger" in 2022. The victim's family in Algeria found out about the verdict three weeks later.
Jennifer Lopez has reportedly spent the night at Ben Affleck's house a "couple times" as they have "lingering doubts" about divorce.
When the measured voltage V G is 0, both legs have equal voltage ratios: R 2 /R 1 = R x /R 3 and R x = R 3 R 2 /R 1. A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit , one leg of which includes the unknown component.
