I really don’t know much about Dua Lipa—but I actually do know something about physics. The dancing in this music video uses some cool physics for some really interesting effects. In this case, the ...

[Valentin] used a simple concept to build this auto-reversing rotating platform. The concept is extremely simple, the leads for the motor are attached to a double-pole double-throw switch which allow ...

If you've ever taken a slow spin in Seattle's Space Needle, you'll understand the allure of Portland architect Ben Kaiser's tiny, twirling house. Here, he's turned convention on its head by taking a ...

The video shows a heavy-duty lifting and rotating platform designed by Physik Instrumente (PI) for test and qualification purposes. The platform has a capacity up to 10 tons load and includes free ...

A person at rest is standing on a low-friction platform or chair and holding a spinning wheel. If the person tilts the wheel, she or he will start rotating according to the law of conservation of ...
