RE: Estimation quiz!
Very good. I thought Pauli's estimate interesting - evidently each of us have our favourite yardsticks. For me, the distance to the Moon is the biggest one(*) in miles, at a quarter of a million. I don't (didn't) even have a figure in mind for the size of the Sun. I think in future I'll count it as nearly a million miles. (I'm from the UK but old enough to be mostly unmetricated.)
A bit of mental arithmetic, reckoning 30 inches to the yard and 1500 yards to the mile, and 30*30 about 1000, got me to the answer of 20 million miles, which isn't too far off. (I'd like to make a joke comparing a Pauli estimate to a Fermi estimate, but I can't do it.) (*) Oh, no, I do have the figure 93 million miles for the distance to the Sun. Perhaps the earliest large number I came across. And two digits of precision! |
