But I learned from each one” he has said.  The count has become one of the most repeated numbers in the history of invention.
It is worth flagging that it comes from Dyson’s own telling, not from anyone counting the machines in his workshop but what the number stands for is more interesting than the numb

Every living koala descends from the small eastern population that survived, then expanded and split into today’s major populations as forests recovered after the last ice age.
