Teen Mathletes Do Battle at Algorithm Olympics

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

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

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.

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

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.

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

Project Amplify is Nike’s latest attempt to put some spring in your step with help from a powered mechanism that enhances the natural movement of the human ankle and lower leg.

Political consultant Bradley Tusk has spent a fortune on mobile voting efforts. Now, he’s launching a protocol to try to mainstream the technology.

Save almost $20 on Microsoft's first-party headset for Xbox Series S/X.

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.

This $400 set comes with minifigures of the complete Next Gen crew, including Picard, Riker, and Wesley Crusher’s portable tractor beam.
