Does Boltzmann's tombstone have "S = k log w" engraved on it?
I heard somewhere that Ludwig Eduard Boltzmann's tombstone has **S = k log w** engraved on it.
Wikipedia repeats the claim without references:
> The equation for S is engraved on Boltzmann's tombstone at the Vienna Zentralfriedhof — his second grave.
Is this true?
Yes, the grave has the formula, and Wikipedia does have this: Boltzmann's entropy formula
