Nonlocal, nonlinear interactions of optical beams can be described by the Newton–Schrödinger equation for quantum gravity, offering an analogue for studying gravitational phenomena. Gravitational ...

We define and explain mathematically through multiple example problems. Segment 4E: Gravitational Potential and Kinetic Energy Gravitational potential energy and kinetic energy are defined and ...

Let's file this post under "mistakes that Rhett made that he doesn't want to make again." If I don't write it down, I won't learn from my mistakes. How about I start this with the following problem.

Albert Einstein in 1920. Although Einstein himself made many advances in physics, from special and general relativity to the photoelectric effect and statistical mechanics, there were many problems he ...
