SPOTLIGHT ON SARGANT
Inspired by a recent soundbyte.
“From high mountain peaks to laboratories deep underground, a garden gnome named Kern has been trotting the globe to reveal a little-known fact about our planet: The force of gravity is not the same everywhere on Earth. Gravity is the force that pulls objects towards Earth.
A company that sells precision scales is behind Kern’s travels. It sends the gnome and a digital scale to scientists around the world. The experiment shows why the company has to adjust each scale it sells to account for local gravity differences.
Kern, who travels alone via the United Parcel Service Inc. (UPS), is weighed by the scientists at each location. Weight is a product of mass times gravity. This means that in spots where gravity is pulling more, Kern will weigh more, and in places where this force is less, the gnome weighs less.
“Kern has by far weighed the heaviest at the South Pole and lightest at Mexico and Mumbai, India,” says James Nester, creator of the Gnome Experiment”.
