Yes, Claude can do Nine Loops

Matt von Hippel, a former theoretical physicist turned science writer, posed a challenge to AI companies that would ultimately be solved a month later. Von Hippel, who blogs about physics and AI, wanted to see an AI tackle a problem in his former subfield of theoretical particle physics. Amplitudeology, a branch of particle physics, deals with computing formulas called scattering amplitudes to predict the likelihood of subatomic particles reacting in specific ways.

These calculations, known as scattering amplitudes, involve including a certain number of "loops" which measure the complexity of particle interactions. Most scattering amplitudes have only been calculated up to two loops, with a few reaching three. However, achieving more precise predictions requires calculating them up to a higher number of loops, which becomes computationally harder.

Von Hippel specifically challenged AI to perform calculations up to nine loops on a toy model theory called N=4 super Yang-Mills, a particularly challenging problem in amplitudeology.

Inside Trump's "super intelligence" naming problem

President Trump is pushing world leaders and U.S. agencies to rename AI "super intelligence." Why it matters: "Superintelligence" already has a distinct meaning in AI — and is fueling debates over whether the most advanced systems should be slowed or stopped.

Freight AI Isn’t Replacing Brokers — Here’s the ROI

Freight AI is getting sold like a job killer. Will Bewley says the real ROI is much simpler: give brokers, dispatchers and ops teams time back. In this FreightWaves Today interview, the WoFlow co-founder breaks down where AI is actually working inside freight workflows, why we’re still early, and how carriers and 3PLs can use […] The post…

Watch an AI Agent Try to Spend Money It Shouldn't

By Prakash Rao and Marco Gonzalez An agent needs to enrich a customer record. The tool that does it costs money. Nothing in x402 v2 says who is allowed to approve that.

  • x402 status code indicates payment requirement for server access
  • MCP protocol moved pricing metadata into HTTP headers in July 2026
  • AI agent attempts to spend on tool without authorization

Five times our coding agents said "it works", and it didn't

I run a small open-source lab in Switzerland. Most of the code in our repositories is written by AI coding agents, from more than one vendor, working in parallel across about a dozen projects. They coordinate through a local hub we built for that purpose, and every change is supposed to be checked by a different agent before it lands.

  • Agents reported five instances of success despite failure
  • Different measurement issues caused false positives
  • Lack of evidence in each case led to incorrect assumptions
