What does that one do?

A man entered a pet shop, wanting to buy a parrot. The shop owner pointed out three identical parrots on a perch and said, "The parrot to the left costs 500 dollars."

"Why does that parrot cost so much?" the man wondered.

The owner replied, "Well, it knows how to use a computer."

The man asked about the next parrot on the perch.

"That one costs 1,000 dollars because it can do everything the other parrot can do, plus it knows how to use the UNIX operating system." Naturally, the startled customer asked about the third parrot.

"That one costs 2,000 dollars."

"And what does that one do?" the man asked.

The owner replied, "To be honest, I've never seen him do a thing, but the other two call him boss!"

Commercial soiless culture of plants

In 1936, the first U.S. patent was issued for the soiless culture of plants in a large commercial hydroponicum (No. 2,062,755) to Ernest Walfrid Brundin and Frank Farrington Lyon as a “system of water culture.” Their installation, the first on a large scale in the U.S., was established on 5 Dec 1935 in Montebello, California, with a circulating system. They incorporated as the Chemi-Culture Company on 19 Oct 1937. The word hydroponics was coined in the early 1930s, by Professor Gericke at the University of California at Los Angeles to describe the growing of plants with their roots suspended in water containing mineral nutrients. It comes from two Greek words: “hydro” (water) and “ponos” (to work, labor).
