A basic pendulum is a mass at the end of a string that swings back and forth. It seems simple, and it appears in most introductory physics textbooks. But it's not a trivial problem to solve for the ...

The new device will still have the same size as the original Digimon Pendulum, but it will come with a lot of new features. Other than full-colored sprites, the device will have an internal battery ...

That big grandfather clock in the library might be an impressive piece of mechanical ingenuity, and an even better example of fine cabinetry, but we’d expect that the accuracy of a pendulum timepiece ...

The narrator observed a pendulum in the choir, understanding its isochronal motion was governed by the wire's length and π. A magnetic device beneath the floor ensured its perpetual oscillation by ...

As a rule, Donald Saff doesn’t collect clocks he can’t see inside of. It’s the harmonic entanglement of gears—and the skill needed to craft them—that first lured him to horology, the study of ...

Converting the vibrations generated by water currents in contact with an object into energy. This is the basis of the new system designed by Francisco Huera, a researcher in the Department of ...

Reaction wheels are useful things, typically used by satellites to keep themselves oriented the right way up in space. Turning the reaction wheel creates an equal and opposite torque in the spacecraft ...
