Lines

One day, there was a catastrophic event that caused all humans on Earth to die. To sort things out, everyone went to Heaven. God came in and said,
"I want the men to make two lines.
One line for the men who ruled their women on Earth and the other line for the men who were ruled by their women. Also, I want all the women to go with St. Peter." With that, the next time God looked, the women were gone and there were two lines.
The line of men who were ruled by their women was 1000 miles long, and in the line of men who ruled their women, there was only one man.
God became angry and said, "You men should be ashamed of yourselves. I created you in my image and you were all whipped by your mates. Look at the only one of my sons who stood up and made me proud. Learn from him!
Tell them, my son, how did you manage to be the only one in this line?"
The man replied, "I don't know, my wife told me to stand here."

Georg Brandt

Died 29 Apr 1768 at age 73 (born 21 Jul 1694). Georg Rushd Brandt was a Swedish chemist who was the first person to discover a metal unknown in ancient times, which he isolated and named cobalt (1730). He published (1733) findings on the composition and solubility of arsenic compounds then researched antimony, bismuth, mercury, and zinc. His work on methods of producing hydrochloric, nitric, and sulfuric acids was published in 1741 and 1743. Brandt was one of the first chemists to completely forswear alchemy, and devoted his later years to exposing fraudulent alchemical processes for producing gold. Ancient Egyptians used tiny amounts of cobalt to make their glass blue. Cobalt is added to steel to make it harder and have a higher melting point. Traces of it are found in meat and dairy products as vitamin B-12.[Note: Brandt's birthdate is given as 21 Jul 1694 in Dictionary of Scientific Biography and Encyclopedia Britannica, but as 26 Jun 1694 in The Discovery of the Elements by Mary Elvira Weeks (1934).]
