Claude computes nine-loop scattering amplitude in N=4 super-Yang-Mills using bootstrap method
What happened
物理学家 Matt von Hippel 之前公开叫板，让 AI 公司在学术级算力下算出 N=4 超对称杨-米尔斯理论的九圈散射振幅。Anthropic 的 Claude 在一个月内做到了。九圈是个已知的计算前沿，圈数越多，计算量指数级暴涨。Claude 用的是 bootstrap 方法，就像玩数独，先列出所有可能，再根据物理规则逐个排除。正文没披露具...

Physicist Matt von Hippel publicly challenged AI companies to compute a nine-loop scattering amplitude in N=4 super-Yang-Mills using only academic-scale compute. Anthropic's Claude pulled it off within a month. Von Hippel explains his choice: more loops mean exponentially harder computation, and nine loops was a known frontier. Claude used a bootstrap method—like solving Sudoku by eliminating impossibilities. The post doesn't disclose the exact compute budget, runtime, or cross-checks against known lower-loop results. I'd treat this as a targeted engineering demo rather than an autonomous theory breakthrough for now.
