A simple question about a spinning needle has haunted mathematicians for more than a century. It led to the Kakeya conjecture, a cornerstone of modern analysis connecting geometry, fractals, and the behavior of waves. Now, mathematicians Hong Wang and Joshua Zahl have cracked the 3D case — a once-in-a-generation breakthroughContinue Reading
Despite the hype, it’s been surprisingly challenging to find quantum algorithms that outperform classical ones. In this episode, UC Berkeley computer scientist, Ewin Tang, discusses her pioneering work in “dequantizing” quantum algorithms and what it means for the future of quantum computing. “The Joy of Why” is a Quanta MagazineContinue Reading
Nearly 3,000 years ago, the ancient Babylonians began one of the longest-running science experiments in history. The goal: to predict eclipses. This singular aim has driven innovation across the history of science and mathematics, from the Saros cycle, to Greek geometry, to Newton’s calculus, to the three-body problem. Today, eclipseContinue Reading
For decades, Shor’s algorithm has been the paragon of the power of quantum computers. This set of instructions allows a machine that can exploit the quirks of quantum physics to break large numbers into their prime factors much faster than a regular, classical computer — potentially laying waste to muchContinue Reading
Researchers Robert Hazen and Michael Wong have put forward a bold new law of nature — one that could explain how everything in the universe evolves, from atoms, minerals and stars to living cells, ecosystems and even human civilization. At the heart of their theory is the idea that informationContinue Reading
