Metrophile is Moving

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

“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.

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

A Turning Point USA official inaccurately claimed a high school's math department wore Halloween costumes that mocked Charlie Kirk. Those teachers are now facing a flood of online attacks and death threats.

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.

Unusually warm ocean temperatures fueled one of the worst hurricanes on record. New research finds climate change increased the storm’s likelihood.

The math behind even the simplest ocean waves is notoriously uncooperative. A team of Italian mathematicians has made major advances toward understanding it.

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

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.

This week on Uncanny Valley, we break down how one of the most common card shufflers could be altered to cheat, and why that matters—even for those who don’t frequent the poker table.

A federal contracting database lists an ICE payment for $61,218 with the payment code for “guided missile warheads and explosive components.” But it appears ICE simply entered the wrong code.

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