1822

On 14 June 1822, Charles Babbage told the Royal Astronomical Society he could build a machine to calculate mathematical tables without human error. He was right about the problem and right about the solution. He never finished building it.

On 6 June 1822, a musket shot on Mackinac Island left Alexis St Martin with a permanent hole in his stomach. Army surgeon William Beaumont spent the next ten years using it to study digestion. St Martin got the wound; science got 51 conclusions.
