While I do love the quote, this is a bit silly:
if the read/write head were a Boeing 747, and the hard-disk platter were the surface of the Earth:
- The head would fly at Mach 800
- At less than one centimeter from the ground
- And count every blade of grass
And if the earth was a perfect sphere. That’s kind of important, too.
(And there was no atmosphere. And each blade of grass was evenly spaced. You just can’t scale dynamics between these sorts of scales.)
