How (Relatively) Simple Symmetries Underlie Our Expanding Universe
Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe. Isaac Newton and other premodern physicists saw space and time...
How the Neutrino’s Tiny Mass Could Help Solve Big Mysteries
The KATRIN experiment is closing in on the mass of the neutrino, which could point to new laws of particle physics and reshape theories of cosmology. Of all the known...
Cosmic Triangles Open a Window to the Origin of Time
...the final answer without ever working through the complicated particle dynamics. The results hinted that the usual picture of particle physics, in which particles move and interact in space and...
A Child’s Puzzle Has Helped Unlock the Secrets of Magnetism
People have known about magnets since ancient times, but the physics of ferromagnetism remains a mystery. Now a familiar puzzle is getting physicists closer to the answer. For a few...
Roberto Peccei and Helen Quinn, Driving Around Stanford in a Clunky Jeep
...or out — in clearing a path to inspiration. Four decades ago, Helen Quinn and Roberto Peccei took on one of the great problems in theoretical particle physics: the strong...
Dark Energy May Be Incompatible With String Theory
...awoke in Vienna and groggily scrolled through an online repository of newly posted physics papers. One title startled him into full consciousness. The paper, by the prominent string theorist Cumrun...
Joe Polchinski’s Restless Pursuit of Quantum Gravity
...or out — in clearing a path to inspiration. As a young professor at Harvard University in 1997, Juan Maldacena reshaped fundamental physics with the discovery that, as he put...
Our Bodies, Our Data
...in physics and other fields. “In high-energy physics, the data is well-structured and annotated, and the infrastructure has been perfected for years through well-designed and funded collaborations,” said Zola. Biological...
A ‘Rebel’ Without a Ph.D.
...achievements in math, physics, astronomy and public affairs. H. T. Yau of Harvard University commenced the math section, launching into Dyson’s work on the universality of random matrices. George Andrews...
