Agentic Physics

Physics, checked by machine.

Describe the physics in words. Agentic Physics states it in Lean 4, proves it, and hands you the file the Lean kernel accepted.

A ball dropped from rest falls ½gt² in time t. Prove it.

How it works

The kernel has the last word.

  1. 01

    Describe

    Write the physics in your own words. Attach a paper or a photo of a derivation.

  2. 02

    State

    The agent writes the theorem in Lean 4. It checks the statement says what you meant before it starts.

  3. 03

    Prove

    It searches Physlib and Mathlib and writes the proof. When it needs a lemma, it proves that first, or asks you.

  4. 04

    Checked

    The Lean kernel decides. Nothing is called proved unless the kernel accepted it.

What you can do

Prove a result

Interactive, or fully on its own. You get the Lean file the kernel accepted.

Check a derivation

Paste the steps you wrote by hand. It says which line breaks. It never rewrites your work.

Work in Lean

A Lean editor in the browser. The kernel checks your file. The agent works beside you.
