Quantum entanglement is challenging researchers to understand how photons seemingly influence each other instantaneously.

When British physicist Roger Penrose suggested in 1969 that energy could be pulled from a rotating black hole, it sparked a ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...

Now back to the torpedo bat. It's designed so that the wider part of the bat IS the sweet spot. Since it’s wider, it's easier to hit the ball. Since that part is the sweet spot, it gives the ball a ...

Optical rotatum” is the term researchers coined to describe a newly discovered structure of light. Beams of light that can be ...
