Mad men are given a test to check their mental state. The instructor draws a door on the wall and orders them to go out.
They start rushing to the door but one remains sitting. The instructor goes to him and asks; “why didn’t you join the others?” He replies, "let them fight they forgot I have the keys"

Robert MayerDied 20 Mar 1878 at age 63 (born 25 Nov 1814). Julius Robert Mayer was a German physicist who, while a ship's doctor sailing to Java, considered the physics of animal heat. In 1842, he measured the mechanical equivalent of heat. His experiment compared the work done by a horse powering a mechanism which stirred paper pulp in a caldron with the temperature rise in the pulp. He held that solar energy was the ultimate source of all energy on earth, both living and nonliving. Mayer had the idea of the conservation of energy before either Joule or Helmholtz. The prominence of these two scientists, however, diminished credit for Mayer's earlier insights. James Joule presented his own value for the mechanical equivalent of heat. Helmhotlz more systematically presented the law of conservation of energy. |
