How to Follow the Trajectory of Comet 3I/Atlas

The interstellar comet 3I/Atlas reached its closest point to the sun. Here's how to follow the rest of its journey away from our solar system.

In Orbit You Have to Slow Down to Speed Up

Driving a spacecraft around a planet isn’t anything like driving on a planet. A physicist explains orbital navigation.

The First Radio Signal From Comet 3I/Atlas Ends the Debate About Its Nature

An observatory detected the first radio signal from the interstellar object 3I/Atlas. Here’s what it means.

Physicists Create a Thermometer for Measuring ‘Quantumness’

“Anomalous” heat flow, which at first appears to violate the second law of thermodynamics, gives physicists a way to detect quantum entanglement without destroying it.

How Do Metal Detectors Work?

What sneaky invisible forces enable these instruments to locate buried treasure?

The ‘10 Martini’ Proof Connects Quantum Mechanics With Infinitely Intricate Mathematical Structures

The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, uses number theory to explain quantum fractals.

Can a Hydroelectric Dam Really Make the Days Longer?

By shifting water to a higher elevation, the giant Three Gorges Dam caused the Earth to spin more slowly.

Unpicking How to Measure the Complexity of Knots

Two mathematicians have proved that a straightforward question—how hard is it to untie a knot?—has a complicated answer.

How Genes Have Harnessed Physics to Grow Living Things

The same pulling force that causes “tears” in a glass of wine also shapes embryos. It’s another example of how genes exploit mechanical forces for growth and development.
