I still remember that Brooklyn lab as if it were yesterday. Not because of the graph, but because of what it revealed: When ...

Trapped and squeezed: A single nanoparticle made of glass (a white point near the centre of the photo) is confined in an optical potential created with a focused laser beam. By detecting the light ...

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 ...

When humans think about time, most imagine a steady flow of seconds ticking into minutes and minutes into hours which carry us from past to present to future. But in the science of quantum physics, ...

The original version of this story appeared in Quanta Magazine. At the turn of the 20th century, the renowned mathematician David Hilbert had a grand ambition to bring a more rigorous, mathematical ...

What if, just before we reach the bottom, we find out that reductionism fails? Big things are made of smaller things, and those smaller things are made of smaller things still. That’s reductionism in ...

Have you ever stopped to wonder how time really works—how we move from one moment to the next, living life as a steady stream of “now” after “now”? This has been an unanswered question for centuries.

Time has an arrow: It only ever seems to move in one direction. The future is always unknown to us, while the past forever remains locked and inaccessible. And yet, the vast majority of the laws of ...

What if time is not as fixed as we thought? Imagine that instead of flowing in one direction—from past to future—time could flow forward or backwards due to processes taking place at the quantum level ...
