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.
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.
Hurricane Melissa Has Meteorologists Terrified
The storm, which is set to make landfall in Jamaica on Tuesday, has stunned meteorologists with its intensity and the speed at which it built.
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.
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.
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.
Climate Change Made Hurricane Melissa 4 Times More Likely, Study Suggests
Unusually warm ocean temperatures fueled one of the worst hurricanes on record. New research finds climate change increased the storm’s likelihood.
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.
Analog Photography: The Beginner’s Guide to Film Cameras
