A teaching tape for BM-07, Infer the molecular number

Perrin's count

Open BM-07 with these settings

Where it starts

The settings the tape begins from, under the constant set scenario-gas-constant-measured. Values are the model's own, not the laboratory control's display: a radius of 5e-7 is half a micrometre.

Inference temperature (T)293.15
Inference viscosity (eta)0.001

What it changes, and what to expect

  1. Set Inference radius (a) to 5e-7 changes how the numbers are read

    Declared radius, historical gas-constant set

    Replay uses the dataset record's own constants. Modern exact k_B is not read.

These are the values the tape's author recorded, not a result this page computed. Nothing here runs the instrument. Open BM-07 with these settings: the link puts them in its form, and it calculates when you apply them. Compare what it gives you with what is recorded here. The settings travel in the link and the laboratory reads them as it loads, so without JavaScript it opens at its worked example instead.
