A man and an ostrich walk into...

A man and an ostrich walk into a restaurant. The waitress asks, "What will it be?"
The man replied "a burger and a coke." "And you?" "I'll have the same," the ostrich replies. They finish their meal and pay. "That will be $4.50," The man reached into his pocket and pulled out the exact amount. They do this every day till Fri.
"The usual?" she asked. "No, today is Friday. I'll have steak and a coke."
"Me too." says the ostrich. They finish and pay. "That will be $10.95"
The man reached in and pulls out the exact amount again just like all week.
The waitress was dumb-founded. "How is it that you always have the exact amount?"
"Well," says the man. "I was cleaning my attic and I found a dusty lamp. I rubbed it and a genie appeared." Wow!" said the waitress. "What did you wish for?"
"I asked that when I needed to pay for something, the exact amount would appear in my pocket." "Amazing! Most people would ask for a million dollars. But what's with the ostrich?" "Well," said the man. "I also asked for a chick with long legs."

Adolf von Baeyer

Died 20 Aug 1917 at age 81 (born 31 Oct 1835). Johann Friedrich Wilhelm Adolf von Baeyer was a German chemist who synthesized indigo (1880) and formulated its structure (1883). He was awarded the Nobel Prize for Chemistry in 1905 "in recognition of his services in the advancement of organic chemistry and the chemical industry, through his work on organic dyes and hydroaromatic compounds". Baeyer also did work on acetylene and polyacetylene, and from this derived the famous Baeyer strain theory of the carbon rings. He studied benzene and cyclic terpene. In this connexion the Baeyer-Villiger oxidation of ketones by means of per-acids was discovered. His work on organic peroxides and oxonium compounds and on the connexion between constitution and colour aroused special interest.
