Wife texts husband on a cold winter morning: "Windows frozen, won't open."
Husband texts back: "Gently pour some lukewarm water over it and then gently tap edges with hammer."
Wife texts back 10 minutes later: "Computer really messed up now."
Karl SchwarzschildDied 11 May 1916 at age 42 (born 9 Oct 1873).German theoretical astrophysicist who made both practical and theoretical contributions to 20th-century astronomy. He developed the use of photography for measuring variable stars. He also investigated the geometrical aberrations of optical systems using ray optics by introducing a perturbation equation which he called the Seidel Eikonal. While on the Russian front during military service, he computed the first two exact solutions of the Einstein Field Equations of General Relativity, one in static isotropic empty space surrounding a massive body (such as a "black hole"), and one inside a spherically symmetric body of constant density - work which led directly to modern research on black holes. |
