How to Make the Universe Think for Us
Physicists are building neural networks out of vibrations, voltages and lasers, arguing that the future of computing lies in exploiting the universe’s complex physical behaviors.
Physicists Rewrite the Fundamental Law That Leads to Disorder
The second law of thermodynamics is among the most sacred in all of science, but it has always rested on 19th century arguments about probability. New arguments trace its true source to the flows of quantum information.
Will the James Webb Space Telescope Reveal Another Earth?
The space telescope is one of the most ambitious scientific projects ever undertaken. Marcia Rieke and Nikole Lewis, two of the scientists leading JWST investigations, talk to Steven Strogatz about how it may transform our understanding of the universe.
Puzzling Quantum Scenario Appears Not to Conserve Energy
By resolving a paradox about light in a box, researchers hope to clarify the concept of energy in quantum theory.
Black Hole Image Reveals the Beast Inside the Milky Way’s Heart
In 2019, the Event Horizon Telescope released a historic image of a supermassive black hole in another galaxy. The follow-up — an image of Sagittarius A* — shows it shimmering at the center of our own.
Powerful ‘Machine Scientists’ Distill the Laws of Physics From Raw Data
Researchers say we’re on the cusp of “GoPro physics,” where a camera can point at an event and an algorithm can identify the underlying physics equation.
Where Do Space, Time and Gravity Come From?
Einstein’s description of curved space-time doesn’t easily mesh with a universe made up of quantum wavefunctions. Theoretical physicist Sean Carroll discusses the quest for quantum gravity with host Steven Strogatz.
Physicists Pin Down How Quantum Uncertainty Sharpens Measurements
Throwing out data seems to make measurements of distances and angles more precise. The reason why has been traced to Heisenberg’s uncertainty principle.
Secrets of the Moon’s Permanent Shadows Are Coming to Light
Robots are about to venture into the sunless depths of lunar craters to investigate ancient water ice trapped there, while remote studies find hints about how water arrives on rocky worlds.
