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 ...

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 ...

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 ...

The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin's Broome Bridge in 1843.

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the ...

Scientists propose that gravitational waves shaped the universe. Their model challenges inflation theory. How exactly did the universe start, and how did these processes determine its formation and ...

Abstract: Wave propagation in a quasiperiodic medium is modeled by a second order homogenized scalar wave equation. The multiscale asymptotic expansion method for high-order homogenization of periodic ...

Astronomers detected in unprecedented detail a collision between two black holes. Their observations confirm predictions made by Albert Einstein and Stephen Hawking.

An exceptionally loud collision between two black holes has been detected by the LIGO gravitational wave observatory, enabling physicists to test a theorem postulated by Stephen Hawking in 1971 ...

"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout." ...
