The Coolest Grave Ever

Located in theViennese Zentralfriedhof, one of the largest cemeteries in the world; Ludwig Boltzmann (February 20, 1844 – September 5, 1906) has the honor of having the coolest grave in the world. His tombstone even bears the inscription of one of his equations:

$S = k \cdot \log W. \,$

Boltzmann was an Austrian physicist who made notable contributions in the fields of statistical mechanics and thermodynamics. He was a strong advocate for atomic theory during a time when it was still controversial, and did a great deal of work on the kinetic theory of gases.
