one guy, one number, and enough atoms to count past the edge of comprehension.
means amedeo avogadro was the italian scientist who proposed that equal volumes of gas at the same temperature and pressure contain equal numbers of particles, the idea behind the constant now named after him.
from born 1776 in turin, trained as a lawyer before switching to physics, he published his hypothesis in 1811 with no way to prove it, dying in 1856 decades before it was confirmed and named in his honor.
