Would you like me to be your friend?

Kathy began a job as an elementary school counselor and she was eager to help.

One day, during recess, Kathy noticed a young girl standing by herself on one side of the playing field while the rest of the kids were playing a game of soccer.

A while later, Kathy walked over to the young girl and offered, "Would you like me to be your friend?"

The girl looked at Kathy suspiciously, then said hesitantly, "Okay, I guess so..."

"Why are you standing here all alone?" asked Kathy.

"Because," the little girl said with great exasperation, "I'm the goalie!"

Henry Augustus Rowland

Died 16 Apr 1901 at age 52 (born 27 Nov 1848). American physicist who invented the concave diffraction grating, which replaced prisms and plane gratings in many applications, and revolutionized spectrum analysis--the resolution of a beam of light into components that differ in wavelength. His first major research was an investigation of the magnetic permeability of iron, steel and nickel, work which won the praise of Maxwell. Another experiment was the first to conclusively demonstrate that the motion of charged bodies produced magnetic effects. In the late 1870s, he established an authoritative figure for the absolute value of the ohm, and redetermined the mechanical equivalent of heat in the early 1880s, demonstrating that the specific heat of water varied with temperature.
