Could One Physics Theory Unlock the Mysteries of the Brain?
The phenomenon of criticality can explain the sudden emergence of new properties in a wide range of complex systems, from avalanches to flocks of birds to stock market crashes. Neuroscientists are now seeking evidence that criticality is at work in the brain’s networks of neurons.
The High Schooler Who Solved a Prime Number Theorem
Daniel Larsen wouldn’t let go of an old question about Carmichael numbers. “It was just stubbornness on my part,” he said.
How Two Physicists Unlocked the Secrets of Two Dimensions
Condensed matter physics is the most active field of contemporary physics and has yielded some of the biggest breakthroughs of the past century. Now for the first time, Jie Shan and Fai Mak, a husband-and-wife team at Cornell University, have figured out a way to create artificial atoms in the lab, opening the door to a new era in research.
The Deep Mystery at the Heart of Life on Earth
As an evolutionary biochemist at University College London, Nick Lane explores the deep mystery of how life evolved on Earth. His hypothesis that life started with primitive metabolic reactions in deep-sea hydrothermal vents illuminates the outsized role that energy may have played in shaping evolution.
Inside the Big Reveal of the Milky Way’s Supermassive Black Hole
Astrophysicists and data scientists on the Event Horizon Telescope team give the backstory behind their new image of Sagittarius A*, the Milky Way’s central supermassive black hole.
