How did hourglass happen? How did they even get the right amount/size of each sand particle/other physical aspects to be aligned with the time?
In: Physics
I think OP approached this thought from the angle of modern small hourglasses. In those, the sand is finer and the hole the sand pours through can have its width calculated to let x amount of sand through.
But the size of the hourglass wasn’t the variable that was changed back then. It was simply the amount of sand. All hour glasses were relatively large and could allow any size sand particle to move through it, and rather than trying to figure out how small they needed to make the neck, they just added more sand.
