Physics professor Walter Lewis demonstrating gyroscope precession. A gyroscope is a device used for maintaining or measuring angular velocity and orientation. Precession is a change in the orientation of the rotational axis of a rotating body. The gyroscope effect was discovered in 1817 by Johann Bohnenberger; the gyroscope was... invented, and the effect named after it, in 1852 by Léon Foucault for an experiment involving the rotation of the Earth. Foucault's experiment to see the Earth's rotation was unsuccessful due to friction, which effectively limited each trial to 8 to 10 minutes, too short a time to observe significant movement. In the 1860s, however, electric motors made the concept feasible, leading to the first prototype gyrocompasses; the first functional marine gyrocompass was developed between 1905 and 1908 by German inventor Hermann Anschütz-Kaempfe.show more

This is a car from the 1960s that never made it to production. The prototype proved that a self balancing gyroscope car could work, but it was still years away from completion. Sadly the company went bankrupt before it could be finished. The Lane Motor Museum purchased the run down prototype car and restored it to it's original condition. The gyroscope is the key to how it works - it uses something called gyroscopic precession which can be tricky to understand. This video explains the car and the mechanism inside.

“They laughed at me in 1897 when I told them about the cosmic ray. Fifty years ago they attempted to discredit my discovery of the rotating magnetic field and my system of power transmission by alternating currents. They called me crazy when I predicted the radio and when I sent the first impulse around the world they said it couldn’t be done.” –Nikola Tesla “In the Realm of Science: Tesla, Who Predicted Radio, Now Looks Forward to Sending Waves to the Moon.” New York Herald Tribune, August 22, 1937. #NikolaTesla #electricity #rotatingmagneticfield #Tesla #history

Antikythera mechanism, an ancient Greek analog computer and orrery used to predict astronomical positions and eclipses for calendar and astrological purposes. Discovered in a shipwreck off the Greek island of Antikythera in 1901, the device dates back to around 100 BCE. It’s considered one of the most astounding technological artifacts of the ancient world. The level of miniaturization and complexity of its parts resembles that of a 19th-century Swiss clock, showing a sophistication that illustrates an understanding of celestial movements with remarkable precision, much like how gyroscopes maintain or measure orientation.

In 1810, the very first gyroscope was made by a German inventor named G. C. Bohenberger. The first gyroscope was actually a heavy ball. In 1817, Johann von Bohnenberger first reported the gyroscopic effect, but it wasn't until 1852 that a man named Jean Foucault created a gyroscope to study the rotation of the earth. The gyroscope's purpose was simple: to prove that the earth spins. Foucault used a heavy wheel mounted on a rod. When he would spin the wheel, it would remain in its spatial alignment relative to the earth.

First practicable gyrocompass. A gyrocompass is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth (or another planetary body if used elsewhere in the universe) to find geographical direction automatically.  The first seaworthy gyrocompass was produced in 1908 by the firm of Hermann Anschütz-Kaempfe in Germany. It was largely made possible through the efforts of Max Schuler, who developed the principles on which a practical shipborne gyrocompass depends. This compass was a marvel of mechanical ingenuity.

Gyroscopic Motion and Conservation of Angular Momentum Gyroscopic motion refers to a spinning object’s inherent tendency to preserve its rotational alignment. As an object rotates, it accumulates angular momentum, which must be conserved. Therefore, the object resists any alteration to its axis of rotation, as such changes would necessitate a modification in its angular momentum. With the gimbal arrangement, it becomes evident that the spinning disc’s axis of rotation remains consistent even when the gyroscope itself is rotated or tilted in three-dimensional space. This phenomenon illustrates the conservation of angular momentum of the spinning disc and the resulting forces generated when the gyroscope’s orientation changes.

Gyroscope precession is the phenomenon where the axis of a spinning gyroscope undergoes a slow, circular motion when a torque is applied. This motion is perpendicular to both the torque and the angular momentum of the gyroscope, illustrating the conservation of angular momentum.

Physics is amazing. I hate physics.
