Particle Physicists Puzzle Over a New Duality
A hidden link has been found between two seemingly unrelated particle collision outcomes. It’s the latest example of a mysterious web of mathematical connections between disparate theories of physics. Last...
Cryptographers Discover a New Foundation for Quantum Secrecy
...to information security in the 1980s, a few researchers discovered that computational hardness wasn’t the only way to safeguard secrets. Quantum theory, originally developed to understand the physics of atoms,...
Physicists Rewrite a Quantum Rule That Clashes With Our Universe
...of Harvard University have collaborated on an effort to replace unitarity in quantum physics with an alternative rule called isometry. Bianca Dittrich, of the Perimeter Institute for Theoretical Physics, struck...
Mass and Angular Momentum, Left Ambiguous by Einstein, Get Defined
...mathematical physicist Roger Penrose, another pioneer of black hole physics, identified the task of characterizing quasilocal mass — “where one does not need to go ‘all the way to infinity’...
Is Gravity Just Entropy Rising? Long-Shot Idea Gets Another Look.
...space-time continuum itself, as emergent from deeper, more microscopic physics. Carney’s line of thinking, known as entropic gravity, pegs that deeper physics as essentially just the physics of heat. It...
The Physicist Decoding the Nonbinary Nature of the Subatomic World
...many of their peers. Many discoveries in physics flow from theory to experiment. Albert Einstein theorized that mass bends the fabric of space-time, and then Arthur Eddington observed the effects...
Quantum Machine Appears to Defy Universe’s Push for Disorder
...Lukin said they observed. The system seems to be imbued with some special physics that allows it to retrace its path, Papić said. “It leaves bread crumbs and goes back...
Beyond the Second Law
...law of thermodynamics has reigned over physics, chemistry, engineering and biology. Now, an upgrade is underway. Thermodynamics — the study of energy — originated during the 1800s, as steam engines...
Tadashi Tokieda’s Special Kind of Magic
...the world in a toy. Tadashi sees in toys, — just like children’s toys, little playthings — the whole universe that’s in there, the principles of physics. He is a...
