7 de may. de 2024 · That year Hippolyte Fizeau directed a beam through rapidly rotating cog teeth toward a mirror miles away. By gauging the beam’s ever-so-slight timing shift on the return trip when the cogs spun towards vs. away, clever Fizeau indirectly captured that vast number. His ingeniously measured value held astonishingly true in every experiment since.
