Extract from Wednesday’s General Relativity class:
Me, at the board writing equations: “…and so the ratio of the earth’s radius to its radius of gyration is about 0.577…”
Student raises hand and asks: “What’s radius of gyration?”
Me: “Er… It’s the average spacing everyone has to give you at the night club when you go Ker-ray-zay on the dance floor.”
As luck would have it, everyone laughed. That would have been a terrible time to have an awkward silence.

Clifford Johnson Indeed, what you want is the Euler-My Sharona constant for this one.
Love it!!
kinda like the nontrivial zeroes of the Reimann zeta function resembling the stat. behavior of the eigenvalues of large random matrices? Ya never know…
Yes!

(Well, as far as I know… the complex sloshy interior of the earth and its oblate shape conspiring to give the Euler-Mascheroni constant would be…. remarkable.)
Andrew: – They coincide in the first three digits, yes… but beyond that, no. (Someone commenting directly on the blog beat you to the punch this time…. 🙂 )
That’s the Euler-Mascheroni Constant, n’est-ce pas? .57721…
Euler – Of course it is 😉 -cvj
So true.

It’s the Euler-Mascheroni constant of course
