We didn't actually land on the moon -- it just looked like we did because of precession. Also, gyroscopes caused 9/11.

Book Review: The Gyroscope of Life
Gyroscopesare entertaining toys and incredibly useful tools. They retain their balance and resist changes to their orientation as long as their flywheel is spinning. As the flywheel slows or stops, the gyroscope wobbles out of control and ultimately quits. Considering their design and function, it’s easy to find parallels between gyroscopes and living systems. Consistent energy inputs keep living…

'Gyroscope' molecules form crystal that's both solid and full of motion
Molecular machines, much smaller than single cells, may one day be able to deliver drugs to kill cancer cells or patrol your body for signs of disease. But many applications of these machines require large arrays of rock-hard moving parts, which would be difficult to build with typical biological structures.
Molecules that makes up the solid crystals found in nature are generally so tightly packed together that there's no room for any of them to move. So despite their strength and durability, solid crystals have generally not been considered for applications in molecular machines, which must have moving parts that can respond to stimuli.
Now, UCLA researchers have formed a crystal out of molecules that resemble gyroscopes with solid frames. Since each molecule has an exterior case surrounding a rotating axis, the crystal has a solid exterior but contains moving parts.
The new crystal, described in the journal Proceedings of the National Academy of Sciences, is the first proof that a single material can be both static and moving, or amphidynamic.
