The Mathematician Who Sculpted the Shape of Space
Eugenio Calabi, who died on September 25, conceived of novel geometric objects that later became fundamental to string theory.
Invisible ‘Demon’ Discovered in Odd Superconductor
Physicists have long suspected that hunks of metal could vibrate in a peculiar way that would be all but invisible. Now physicists have spotted these “demon modes.”
Nobel Prize Honors Inventors of ‘Quantum Dot’ Nanoparticles
The Nobel Prize in Chemistry has been awarded to three researchers who harnessed the quantum behaviors of semiconductor nanocrystals.
Physicists Who Explored Tiny Glimpses of Time Win Nobel Prize
The development of attosecond pulses of light allowed researchers to explore the frame-by-frame movement of electrons.
In the Milky Way’s Stars, a History of Violence
Our galaxy's stars keep a record of its past. By reading those stories, astronomers are learning more about how the Milky Way came to be — and about the galaxy we live in today.
The Experimental Cosmologist Hunting for the First Sunrise
To catch even a whiff of the universe’s earliest epochs — an age of darkness, and one of new light — Cynthia Chiang builds her own equipment. Then she deploys it at the ends of the Earth.
Machine Learning Aids Classical Modeling of Quantum Systems
By using “classical shadows,” ordinary computers can beat quantum computers at the tricky task of understanding quantum behaviors.
Physicists Observe ‘Unobservable’ Quantum Phase Transition
Measurement and entanglement both have a “spooky” nonlocal flavor to them. Now physicists are harnessing that nonlocality to probe the spread of quantum information and control it.
How Scientists Are Tackling the Tricky Task of Solar Cycle Prediction
Scientists have struggled to accurately forecast the strength of the sun’s 11-year cycle — even after centuries of solar observations.
