A teaching tape for BM-01, Tracer Ensemble and Observable Selection
Einstein's 0.8 micron particle
Scrub the observation interval and see the printed displacement figures reproduced under the historical constant set.
Open BM-01 with these settings
Where it starts
| Setting | Value |
|---|---|
| Temperature (T) | 290.15 |
| Viscosity (eta) | 0.00135 |
| Radius (a) | 5e-7 |
What it changes, and what to expect
Set Observation interval (interval) to 1 changes how it is watched, not what happens
Einstein's printed 1-second interval
Einstein printed lambda_x = 8e-5 cm = 0,8 Mikron for 1 s.
What the author recorded that a reader should see here. Quantity Expected Under lambda_x at 1 s 0.794783 μm einstein-1905-brownian-printed Set Observation interval (interval) to 60 changes how it is watched, not what happens
Einstein's printed 60-second interval
Einstein printed ca. 6 Mikron for 1 min.
What the author recorded that a reader should see here. Quantity Expected Under lambda_x at 60 s 6.15637 μm einstein-1905-brownian-printed
These are the values the tape's author recorded, not a result this page computed. Nothing here runs the instrument. Open BM-01 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.
