A gyroscope is a device that resists changes in orientation because a portion of its mass is rapidly revolving.
This is called the conservation of angular momentum and can be directly derived from Isaac Newton’s laws of motion, specifically the third, which states that for every action, there is an equal and opposite reaction.
The modern free-spinning gyroscope was invented to aid navigation of sailing ships, since it could maintain orientation despite the ship rocking in the waves.
Since then, gyroscopes have become much smaller and more ubiquitous. Smart phones, cars, and even watches now include tiny gyroscopes.
Aviation and space flight would be much more difficult without gyroscopes. Some of the most precise gyroscopes ever built are onboard the Hubble and James Webb space telescopes to ensure perfect stabilization for the long exposures required for imaging deep space objects.

Gyroscope measures approximately 4" x 3"
