Artificial Intelligence and Math
AI systems have revolutionized many areas of science and society. Now, they are transforming the field of mathematics, reports Siobhan Roberts for The New York Times. Before a computer can tackle a math problem, it must be able to understand the problem. Last year, Steven Strogatz talked with the mathematician Kevin Buzzard on The Joy of Why podcast about how to translate math into a programming language called Lean. In 2022, computers took on an age-old math problem involving the multiplication of matrices. As Ben Brubaker reported for Quanta, an AI system found a faster algorithm for multiplying certain matrices than humans ever did.
Quasar Signals Slowed by Expanding Universe
Astronomers watching the flashing radiation from distant quasars have found that the signals are slowed by the expansion of the universe, reports Ian Sample for The Guardian. It's the first time the effect of time dilation has been observed in quasars. The observation further deepens scientists' confidence that Einstein's relativistic picture of the universe is correct. In 2022, physicist Sean Carroll explained for Quanta how relativity works and how some aspects of the theory predated Einstein. | |
