1 pieces @ 18” On your 18” PVC pipe, drill (11) 1/8” holes 1 ½” apart starting 1 ½” from one end as shown. The last hole should end up 1 ½” from the other end. Holes need to be drilled all the way ...

A Foucault pendulum is a simple device for observing the Earth's rotation. While such pendulums have been around for more than 150 years and are a staple of the modern science museum, they are ...

In 1851, the French physicist Léon Foucault provided an experimental proof of the Earth’s rotation using a pendulum. Although Foucault is best known for this ingenious experiment, he also made several ...

Physicists have explained yet another quirk of the quantum world: why, if you swing a pendulum through a quantum fluid, it speeds up rather than slowing down. Tiny “quasiparticles” ricocheting around ...

Because a pendulum's oscillation frequency depends on its length, not its mass, you can use different colored bowling balls for a pretty effect. By Francie Diep Published Sep 8, 2014 7:20 PM EDT Get ...

“The only skyscraping girls’ school in the world” is small (600 students) Mundelein College, which is lodged near Lake Michigan in a 15-story building on Chicago’s North Side. A popular teacher of ...

The 350-year-old mystery of why pendulum clocks hanging from the same wall can influence each other and synchronize over time may hold even more secrets than previously thought, researchers say.

What's nerdier than creating an online avatar that fights dragons and raids strongholds? Creating a virtual pendulum that you can sync up to your real-life pendulum. Leave it to physicists to do just ...

Gravity is, at heart, a mystery. Yes, we can talk about curvature of space-time and perhaps make analogies with stretched rubber sheets. But we don’t know why mass causes space-time to curve. To put ...
