Run your own law

PhysWall inverts a closed, non-linear physical law at a single measurement point — and refuses when the inverse is not unique.

Give it a closed law and a measurement. It derives the quantity you cannot measure directly — or tells you exactly why it will not.

Start from one of these

⚠ This tool computes in your browser, and JavaScript is off. The controls below will move and nothing will happen: the chart stays empty and no verdict is produced. The text on this page describes what the tool would show, and it is describing something that is not there.

quantity — what you are deriving

measured

forward — the law, written out

inputs — name = value, one per line

OPTIONAL — and each one buys something

inverse — and it derives instead of only checking

plausible low — and it becomes a verdict

plausible high

name — and if we know the published band, we compare

What runs where

Your declaration is sent to the server and the engine runs there. Nothing about the engine comes back — the response carries a verdict, the derived value, and an echo of what the server understood your formula to say.

There is one implementation, in Python. The version of this page that ran the engine in your browser was a second one, and the two had already drifted: a refusal added to one was missing from the other. One engine cannot drift from itself.

Maturity: beta. it runs a law you write, and nothing here has checked that law.

A checking tool, not professional advice. It tells you what a measurement does and does not support; what to do about that is your decision.
