WRONG IDEAS The earth is flat. The sun, moon, stars rotate the earth each day.
In the 6th century B.C. －ARISTARCHUS • 1543, COPERNICUS
In 1851, a French physicist named FOUCAULT found a way to prove the earth rotates via a OENDULUM FOUCAULT’s first demonstration FOUCAULT’s second demonstration FOUCAULT’s third demonstration
TODAY -- you can see this FOUCAULT PENDULUM demonstration yourself at theCALIFORNIA ACADEMY OF SCIENCES.
Why does the pendulum demonstrate the rotation of the earth?? Let's consider -- what ARE the forces acting on the pendulum?
We must understand the difference between 2 kinds of motions Twisting Traveling
If the Pendulum was at the EQUATOR If the Pendulum was at the POLE
Degrees of TWIST per day may be determined mathematically by this formula and can be demonstrated by using the pendulum Latitude = angular distance of a place from the equator
EXAMPLE by a Foucault Pendulum, man can demonstrate at any point on the Earth's surface (except on the equator) that the earth rotates--
