Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...

In this video, we explain the conservation of angular momentum in AP Physics 1, showing why angular momentum remains constant and how it applies to rotating systems. You’ll see clear examples that ...

You can take any particle in the Universe and isolate it from everything else, yet there are some properties that can never be taken away. These are intrinsic, physical properties of the particle ...

Discover how the Earth started spinning, the impact of the Theia collision, and how the Moon's gravity is gradually slowing ...

This orbital angular momentum has recently gained a lot of attention, as researchers hope to encode information into it and thus either enhance the capacity of fiber optical communication systems, or ...

The proposed diffractive deep neural network employs orbital angular momentum encoding and diffractive layers to process spatial information from handwritten digits, offering a robust and versatile ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...

Speedy Spinning Spheres! Using spheres, cylinders, and straws, the Crew and Dr. Rob learn about inertia, velocity, and conservation of energy due to angular momentum. STEM Challenge: Angular Momentum ...

The inner solar system spins much more slowly than the laws of modern physics predict, and a new study may help to explain why. A thin disk of gas and dust — known as an accretion disk — spirals ...
