‘Outsiders’ Crack 50-Year-Old Math Problem
...different to Kalai. It seemed connected to the famous Kadison-Singer problem, a question about the foundations of quantum physics that had remained unsolved for almost 50 years. Over the decades,...
A Grand Theory of Wrinkles
...but they don’t provide much insight into the underlying physics. “There are these huge programs where they basically just put everything and the kitchen sink into it, and then yeah,...
A Tricky Path to Quantum-Safe Encryption
...years. By exploiting the probabilistic rules of quantum physics, the devices could decrypt most of the world’s “secure” data, from NSA secrets to bank records to email passwords. Aware of...
Peering Into the Early Universe
...fields of astronomy, physics and cosmology. In addition to the planned experiments, scientists hope to be surprised by unforeseen, paradigm-shifting observations, the way a previous generation of four-meter telescopes discovered...
A Bold Critic of the Big Bang’s ‘Smoking Gun’
In mid-March, a panel of four astrophysicists working on an experiment to probe the first moments of time held an extraordinary press conference at the Harvard-Smithsonian Center for Astrophysics (CfA)...
Tiny Tests Seek the Universe’s Big Mysteries
...of exotic physics that could be visible at scales just below the thickness of a dollar bill — provided you build a clever-enough experiment, one small enough to fit on...
Priya Natarajan on Black Holes and Mapping the Universe
...you know, like, a very sort of strong sense of being grounded in physics and foundations of physics and mathematics. And, so, I often come up with a diagram, like,...
Quantum Complexity Shows How to Escape Hawking’s Black Hole Paradox
...foundations of most modern theories, including the celebrated Standard Model of particle physics. Physicists expect semiclassical physics to falter when gravity grows intense, as it does at the still-inscrutable center...
Isadore Singer Transcended Mathematical Boundaries
...well as those between mathematics and quantum physics. He pursued deep questions and inspired others in his original research, wide-ranging lectures, mentoring of young researchers and advocacy in the public...
