I just stumbled upon this TED talk by Deb Roy, a cognitive scientist at the MIT media lab. He did something amazing, something I would never consider doing – he set up video cameras in every room of his house to record his family’s waking moments. This is what he refers to as the “ultimate memory machine”, recording 90,000 hours of home video in the first years of his son’s life. All of those hours yielded a remarkable amount of data, from which Roy and his research team learned about a baby’s acquisition of language. The data visualizations they created are stunning.
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.
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.
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.
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.
How Do Metal Detectors Work?
What sneaky invisible forces enable these instruments to locate buried treasure?
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.
The Hidden Math of Ocean Waves
The math behind even the simplest ocean waves is notoriously uncooperative. A team of Italian mathematicians has made major advances toward understanding it.
