PhysSandbox

Find out why your experiment gave the wrong answer. Every calculation, including code an AI writes, runs sealed off from the internet and from this server.

What went wrong?

Choose the experiment, say what you expected, and add your data.

Measured against expected

Fits and uncertainties come from physics code run in the glovebox, never from the model.

3

Likely causes

Each suspect is scored by how well it explains the evidence. The tick shows where it stood before your last test.

4

Test next

The bench test that best separates the leading suspects per minute of your time.

Ask the agent

An AI writes Python to answer your question. We assume that code is hostile and run it in the glovebox anyway.
