Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

Stephen Hawking was told he had 2 years to live—then revolutionized physics for 50. He passed in 2018, but his cosmic legacy lives on. This is why it seems like everyone has ADHD right now ...

The source of the Milky Way's strange wobble has finally been revealed, thanks to new data from the ESA's Gaia Space Telescope.

"With this, we can detect very tiny changes in both position and momentum at once, beyond the limit of any classical sensor," the authors explained.

A giant 'wave' is rippling through the Milky Way, pushing thousands of stars across the galaxy, and scientists don't know what triggered it.

Abstract: The technique of solving differential equations using Physics-Informed Neural Networks (PINNs) has received extensive attention and application. However, employing neural networks with ...

For centuries, scientific progress has depended on more precise tools for measuring the world around us. Galileo’s telescope revealed Jupiter’s moons and shook the geocentric universe.

Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if they are instead gravastars, fuzzballs or something else entirely ...

Time-varying systems, materials with properties that change over time, have opened new possibilities for the experimental manipulation of waves. Contrarily to static systems, which exhibit the same ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Abstract: In this paper, A new alternating direction decomposition(ADD) solution method is used for the split-step Fourier algorithm of the parabolic equation. The diffraction term factor is ...
