WHAT: The NJIT Math Club will make a Foucault pendulum to prove that the Earth rotates. Club members will affix a long cable to a ceiling in a campus building and tie a bowling ball to the end of the cable. The cable will dangle down six flights. Students in the club will then let the ball sway as they chart its trajectory. Foucault’s pendulum was the first easy-to-see experiment that proved the rotation of the Earth by showing that the sway of the ball is not straight.
WHO: Jonathan Lansey, president of the NJIT Math Club, and Ike Agbanusi, a club member, will do the demonstration with the support of their adviser, Roy Goodman, PhD, assistant professor in the department of mathematical sciences.
WHEN: Tuesday, Nov. 15, at 2:30 p.m.
WHERE: The students will set up and perform the Foucault pendulum demonstration in the rear stairway of Fenster Hall.
BACKGROUND: A Foucault pendulum, named after the French physicist Leon Foucault, was conceived as an experiment to demonstrate the rotation of the Earth in 1851. Ever since then, students have used the demonstration to see for themselves the effect of the earth’s rotation on moving objects.
