Dividing E. coli in SEM
A scanning electron micrograph makes the dividing wall of Escherichia coli visible at a scale far below unaided sight.

Visual Lab experiment
Scale / Viewpoint Explorer
Move across base-10 orders of magnitude and change normalized framing. The visual is a teaching diagram, not a measured photograph, microscopy calibration, map scale or scientific simulation.
Controls
Current visualization
Default state: 10^0 m (1 metre) with 50% normalized framing. The ruler is illustrative and does not estimate the dimensions of any linked BVU subject.
Reviewed BVU context
Real subjects, kept separate from the experiment.
These entries provide reviewed source/provenance context. Their media and claims are not rewritten by the controls above.

Practice on reviewed subjects
Carry the lab question back to evidence.
The lab is synthetic practice. These subject links show where the same reading question matters in reviewed BVU records without changing the record itself.
