A new crew of potential ripples in spacetime has just debuted — emphasis on the word “potential.” By loosening the criteria for what qualifies as evidence for gravitational waves, physicists ...

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.

Hypervelocity stars have, since the 1920s, been an important tool that allows astronomers to study the properties of the ...

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 ...

In this video, we dive into gravitational potential energy and how to calculate it using numerical integrals in Python. Learn how to set up the equations, perform the integration, and visualize the ...

In the UK, falls in hospital are the most commonly reported patient safety incident. Risk is multifactorial and increases with age, some medications, and conditions such as delirium and dementia.
