From Can’t Explain Raw capture

Capture — 1.5 metres

Verbatim

The 150-character SMS, endorsed by Professor Brendan Murphy:

Coronavirus Aus Gov msg: To stop the spread, stay 1.5m from others, follow rules on social gatherings, wash hands, stay home if sick.

Hunt’s longer list, same release:

Be at least 1.5 metres away from everyone and don’t gather with others

What the number was doing

1.5 m is a droplet rule: large drops fall. Aerosols do not respect a tape measure indoors. The SMS says “stop the spread,” not “reduce close-range spray.”

What this file does not do

It does not file “distance did nothing.” Crowding is a risk. It files the slide from a droplet heuristic to a hard line that would stop the spread.
