Sir Humphry Davy

Born 17 Dec 1778; died 29 May 1829 at age 50. English chemist (Baronet), who discovered several chemical elements and compounds, invented the miner's safety lamp, and epitomized the scientific method. With appointment to the Pneumatic Institution to study the physiological effects of new gases, Davy inhaled gases (1800), such as nitrous oxide (laughing gas) and a nearly fatal inhalation of water gas, (a mixture of hydrogen and carbon monoxide). Davy discovered alkali metals: potassium and sodium, an isolation made with electric current for the first time (1807); as well as alkaline earth metals: calcium, strontium, barium, and magnesium (1808). He discovered boron at the same time as Gay-Lussac. He recognized chlorine as an element, which prior workers confused as a compound.

Once upon a time Dracula decided to carry some sort of a competition to see which is the finest bat to stand on his side. So all the bats were honored to take part. The rules were simple. Whichever bat drinks more blood, will be the winner? So the first bat goes and comes back after 10 minutes. Her mouth was full of blood. Dracula says: "Congratulations, how did you do that?" The bat said: "Do you see that tower? Behind it there is a house. I went in and sucked the blood of all the family". "Very good" said Dracula. The second bat goes and comes back after 5 minutes all her face covered in blood. Dracula astonished says, "How did you do that?" The bat replies " Do you see that tower? Behind it there is a school. I went in and drunk the blood of all the children". "Impressive" said Dracula. Now the third bat goes and comes back after three minutes literally covered in blood from top to toe. Dracula is stunned. "How on earth did you do that????" he asked. And the bat replies. "Do you see this tower?" Dracula replies with a yes. And the bat says "Well, I didn't".
