Fun at the zoo!

Little Johnny wanted to go to the zoo and pestered his parents for days. Finally his mother talked his reluctant father into taking him.

"So how was it?" his mother asked when they returned home.

"Great," Little Johnny replied.

"Did you and your father have a good time?" asked his mother.

"Yeah, Daddy especially liked it," exclaimed Little Johnny excitedly, especially when one of the animals came home at 30 to 1!"

Harold Stephen Black

Born 14 Apr 1898; died 11 Dec 1983 at age 85.American electrical engineer who discovered and developed the negative-feedback principle, in which amplification output is fed back into the input, thus producing nearly distortionless and steady amplification. In 1921, Black joined the forerunner of Bell Labs, in New York City, working on elimination of distortion. After six years of persistence, Black conceived his negative feedback amplifier in a flash commuting to work aboard the ferry. Basically, the concept involved feeding systems output back to the input as a method of system control. The principle has found widespread applications in electronics, including industrial, military, and consumer electronics, weaponry, analog computers, and such biomechanical devices as pacemakers.
