A man takes his Rottweiler to...

A man takes his Rottweiler to the vet.
"My dog is cross-eyed," the man says. "Is there anything you can do for him?"
"Well," says the vet, "let's have a look at him."
So he picks the dog up and examines his eyes and ears and then checks his teeth. Finally, he says, "I'm going to have to put him down."
"What?" The man was astonished. "Why? Because he's cross-eyed?"
"No," said the vet, "because he's really heavy!"

Xerography

In 1938, xerography was demonstrated by Chester F. Carlson. With his assistant, Otto Kornei, Carlson used a sulphur coating on a zinc plate, vigorously rubbed with a handkerchief to apply an electrostatic charge. A glass slide was prepared using India ink to write "10-22-38 ASTORIA," then laid on the sulphur surface in a darkened room. After illuminating them with a bright incandescent lamp for a few seconds, the slide was removed. When lycopodium powder was sprinkled on the sulphur surface and blown off, there remained a near-perfect image of the writing. Permanent copies were made by transferring the powder images to wax paper and heating the sheets to melt the wax. Xerox is a term coming from "xerography" which means dry writing and is a trademark.
