The world’s fastest supercomputer is called Fugaku and it discovered that 100% of airborne droplets of less than 5 micrometres escaped through plastic visors, like the ones used by people who work in service industries. (A micrometre is one millionth of a metre).
Of larger droplets which measure 50 micrometres, about half were able to escape into the surrounding air–a fact confirmed by a government-backed research institute in Kobe, Japan called Riken.
The supercomputer, which cost 130 billion yen (or $1.2 billion) has
