Each evening bird-lover Tom stood in his backyard, hooting like an owl. One night, an owl called back to him. For a year, the man and his feathered friend hooted back and forth. He even kept a log of the "conversation."
Just as he thought he was on the verge of a breakthrough in interspecies communication, his wife had a chat with her next-door neighbor.
"My husband spends his nights... calling out to owls," she said.
"That's odd," the neighbor replied. "So does my husband."

Iodine discovery announced

In 1813, a new substance - iodine - was announced at the French Institute by Nicolas Clément, in the name of its discoverer, Bernard Courtois. In 1811, Courtois had observed violet crystals with a metallic lustre that condensed from the vapour rising from the mother liquor of seaweed ash being leeched in sulphuric acid at his family's saltpetre business in Dijon. Although he made a preliminary investigation of this substance, he lacked the resources to fully research it. For this he turned to C.B. Desormes and Nicolas Clément. They suspected the substance was similar to chlorine, but confirmation of its nature as an element was made independently by Joseph-Louis Gay-Lussac, who named it iode, and Humphry Davy (1814).[Ref: Clément, N., Découverte d'une Substance Nouvelle dans l'Vareck par M.B. Courtois. Ann. Chim., 88, 304-310, 1813.] [Image: iodine crystals deposited from vapour on a col glass surface.]
