Nobody expected the Spanish Inquisition, but then again no one could have predicted the giraffe, the iPhone or JD Vance. The laws of physics don't demand them; they all just evolved, expressions of how (for better or worse) things happened to turn out. Ecologist Mark Vellend's thesis is that to understand the world, physics and evolution are the only two things you need. Evolution, here, refers in the most general sense to outcomes that depend on what has gone before.

The exploration of color has deep implications for art, physics, and perception that date back centuries, engaging thinkers from Isaac Newton to contemporary scientists.

Nothing can exceed the ultimate speed limit set by the laws of physics, known as the speed of light in a vacuum, or 299,792,458 m/s.

Lasers, invented in 1958, allow for the production of truly monochromatic light through stimulated emission, achieving specific wavelengths and building photon density in a cavity.

My first encounter with physics came when I was eight years old, inspired by the story of a great scientist who left an unfinished manuscript on his desk. This sparked my fascination with the universe and the fundamental laws governing it, particularly the legacy of Einstein and his elusive theory of everything, which aims to encapsulate the workings of the cosmos in a single equation.

The idea of levitating off the ground has captivated human imagination, and quantum levitation demonstrates that specially-made materials can float indefinitely above magnets under the right conditions.

The idea of speeding up Earth's rotation to halve a day presents challenges like redefining time and can lead to insights into physics and potential innovations.

Emmy Noether established a profound connection between symmetries in physics and conservation laws, revealing that not all systems adhere to strict energy conservation principles.

The ongoing interplay between theory and experiment in physics is critical; when discrepancies arise, they signal opportunities for deeper understanding and potential paradigm shifts.

What you actually carry around is a tiny slab of black magic-an object so packed with impossibility that, if you understood even half of what it's doing right now, you'd either laugh out loud or quietly set it on fire.

"The real behavior of a rolling object is largely a function of its geometry. This insight is essential for accurately predicting how rigid bodies will behave in various contexts."

"In order to succeed, a perpetual motion machine should be free of friction, run in a vacuum chamber and be totally silent since sound equates to energy loss."

Since H.G. Wells combined the words "time travel" - and used them so systematically to refer to using a machine to travel to a certain date in the calendar - in The Time Machine in 1895, scientists and the public at large have been fascinated with its possibility.

Dr. Richard Garwin, a prominent physicist and advisor, contributed to nuclear weaponry, advanced technologies, and advocated for arms control throughout his distinguished career.

The technique aims to democratize fertility testing by providing a cost-effective, at-home alternative that measures sperm motility rather than relying solely on lab-based examinations.

This study into cacio e pepe illustrates how traditional cooking can be explored through a scientific lens, making it accessible for those who struggle with the dish.

'The universe evolves in a way that the information content in it is compressed, optimized and organized - just as computers and computer code do.'

According to mathematics if you have a square table with legs at the corners, and it's resting on a bumpy floor, there will always be a way of making all four of the legs touch the ground.

On Thursday, researchers unveiled the most precise measurement yet of a neutrino, scaling down the maximum possible mass of the ghostly specks of matter that permeate our universe.
