A Scottish lad and lass were sitting together on a heathery hill in the Highlands. They had been silent for a while, then the lass said, "A penny for your thoughts."
The lad was a bit abashed, but he finally said, "Well, I was thinkin' how nice it would be if ye'd give me a wee bit of a kiss."
So she did so.
But he again lapsed into a pensive mood which lasted long enough for the lass to ask him, "What are ye thinkin' now?"
To which the lad replied: "Well, I was hopin' ye hadn't forgot the penny!"

Robert Mayer

Died 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.
