An Unexpected Twist Lights Up the Secrets of Turbulence
...the researchers to see and closely measure the evolution of the vortices. Then they had a lucky break: They took to writing on the hydrofoils with a Sharpie to help...
Deep Neural Networks Help to Explain Living Brains
...the performance of humans, who are extremely good at recognizing objects despite variation. Unbeknownst to Yamins, a revolution brewing in the world of computer vision would also independently validate the...
Physicists Pin Down Nuclear Reaction From Moments After the Big Bang
...time. Cosmologists want to check whether the density of the cosmos changed from one period to the other as expected based on their models of cosmic evolution. If the two...
What Is a Particle?
...said. “Then we can say, ‘Aha, now I can see why this picture can be interpreted as evolution.’” It-from-qubit and amplitudeology approach the big questions so differently that it’s hard...
Searching Symbols for the Rules of Change
...has focused on understanding dynamical systems. Could you explain what those are? I’m thinking about abstract systems and studying their evolution to understand what kind of predictions can be made...
Contemplating the End of Physics
...of physics they will have to obey. But all of this is now changing. Nature’s agonizingly slow process of discovery, driven by cosmological and biological evolution on time scales of...
A New Theorem Maps Out the Limits of Quantum Physics
...— so much so, in fact, that they reverse the quantum evolution of the entire system. They undo the friend’s measurement, erase the friend’s memory, and restore the particle to...
Catherine Dulac Finds Brain Circuitry Behind Sex-Specific Behaviors
...do not have this organ for sensing pheromones. However, the areas of the brain controlling essential behaviors are thought to be conserved in evolution in all vertebrates, particularly the parts...
The New History of the Milky Way
...mapped the movement of just thousands. The data brought a previously static swath of the galaxy to life. “Gaia started a new revolution,” said Federico Sestito, an astronomer at the...
