Over the last few years eating meat has increasingly been associated with health risks, like heart disease, cancer and an early death. How unhealthy is meat really? Find out in this episode of “In a Nutshell.” [Kurzgesagt – In a Nutshell]

Angular Momentum Demo: Hoberman Sphere [Video]

This is a demonstration of the conservation of angular momentum using a Hoberman sphere, a plastic sphere frame that can be contracted by pulling on a string. Pulling on the string while the sphere is rotating causes the sphere’s moment of inertia to decrease and its angular speed to increase, demonstrating conservation of angular momentum. […]
