She: It's not that big.
He: I think we can agree everything below the average between a Planck length and the size of the observable universe is objectively small, and everything above is objectively large. Using the geometric mean, that average is about 0.12 mm. Therefore my penis is actually large.
She: I shouldn't have married a physicist.
- leni536 7mo agoAverage? So around half the size of the observable universe?
- quietbritishjim 7mo agoThey specified the geometric mean. The arithmetic mean (what you're thinking of) of 1 and 100 is 50.5. The geometric mean of 1 and 100 is 10. It gives a sense of the average magnitude.
- leni536 7mo agoThey edited the comment, previously it did not mention geometric mean.
- cubefox 7mo agoThe geometric mean seems to be the natural mean for relative comparisons between lengths, because the mean of (Planck length, observable universe) is clearly very different from the mean of (house, observable universe).
- zahlman 7mo ago> Using the geometric mean, that average is about 0.12 mm That's... actually kinda cool to know.
