A man walked into work on Monday with two black eyes. His boss asked what happened.
The man said, "I was sitting behind a big woman at church. When we stood up to sing hymns, I noticed that her dress was caught in her crack, so I pulled it out. She turned around and punched me square in the eye."
"Where did you get the other shiner?" the boss asked.
"Well," the man said, "I figured she didn't want it out, so I pushed it back in."
First glass plate photoIn 1839, John Herschel made the first (remaining) photograph on glass plate. The image he captured was of the 40-foot, 48" aperture telescope used by his father William Herschel, in Slough, England. It had sat decades without use, and was dismantled a short time later. Twenty years earlier, in 1819, Herschel published the results of his experiments with silver and salts. A chance comment about Daguerre's experiments in a letter to his wife on 22 Jan 1839 from a friend prompted John into new activity, and within a few days, he had prepared some photographs. In papers he published in 1840-42, he coined the new words "emulsion", "positive" and "negative" and reinforced Stenger's earlier introduction of the word "photography."« |
