Bert always wanted a pair of authentic cowboy boots, so, seeing some on sale, he bought a pair and wore them home.
Walking proudly, he sauntered in to the kitchen and said to his wife, Margaret, "Notice anything different about me?"
Margaret looked him over, "Nope."
Frustrated, Bert stormed off in to the bedroom, undressed and walked back in to the kitchen completely naked except for the boots.
Again he asked Margaret, a little louder this time, "Notice anything different NOW?"
Margaret looked up and said in her best deadpan, "Bert. What's different? It's hanging down today, it was hanging down yesterday, and it will be hanging down again tomorrow."
Furious, Bert yelled, "And do you know why it's hanging down?"
"Nope. Not a clue," she replied.
"It's hanging down, because it's looking at my new boots!"
And without missing a beat Margaret replied, "Shoulda bought a new hat, Bert."

Alfred Werner

Born 12 Dec 1866; died 15 Nov 1919 at age 52.Swiss chemist whose founding research into the structure of coordination compounds brought him the 1913 Nobel Prize for Chemistry. He demonstrated that stereochemistry was not just the property of carbon compounds, but was general to the whole of chemistry. His theory of chemical coordination (1893) recognized that many metals appeared to show variable valence and form complex compounds. Certain metals, such as cobalt and platinum, were capable through their secondary valences of joining to themselves a certain number of atoms or molecules. These were termed by Werner “coordination compounds.”and the maximum number of atoms (or “ligands”as he called them) that can be joined to the central metal is its coordination number.
