Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease ...

New data reveals black hole jets can accelerate at speeds defying all physical laws, leaving astronomers without a clear ...

To further understand the phenomenon, precise measurements of the energy spectra of various cosmic ray species and their respective "knee" regions are essential. However, due to the rarity of cosmic ...

When an intense laser pulse hits a stationary electron, it performs a trembling motion at the frequency of the light field.

A tool called AI-Newton can derive scientific laws from raw data, but is some way from developing human-like reasoning.

When an intense laser pulse hits an electron at rest, the latter performs a quiver motion with the frequency of the light ...

A particle accelerator that produces intense X-rays could be squeezed into a device that fits on a table, my colleagues and I ...

We break down Einstein's famous twin paradox to illustrate time dilation in special relativity. Discover how acceleration, ...

Avi Loeb says 3I/Atlas is gaining speed as new images show unusual tail changes. We unpack the data, comet physics, and whether it poses any risk.

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called ...
