Physicist's blog challenge: Claude computes nine-loop Feynman integral

Science writer and former theoretical physicist Matt von Hippel issued a public challenge for an AI model to tackle a computationally demanding problem from his former field of theoretical physics. Within about a month, Anthropic's Claude was shown to complete the task, calculating a nine-loop result that von Hippel says was hard not because the method was unknown but because the computation itself was formidable.

Physicists Say Holographic Principle Unifies Gravity and Quantum Mechanics

Theoretical physicists have developed the AdS/CFT correspondence, a mathematical framework showing that a gravitational theory in a given volume of space is equivalent to a quantum theory operating on its boundary surface. The idea, now known broadly as the holographic principle, implies that the amount of information in a region depends on its surface area rather than its volume, and it underlies a widely accepted resolution to the black hole information paradox that Stephen Hawking raised.
