Before the mid-18th century, navigators were unable to accurately determine their longitude at sea. In an effort to encourage innovators to develop a method for precisely determining a ship's longitude, the British government began offering a prize in 1714. In 1735, John Harrison invented the first timepiece accurate enough to be used in such calculations. He spent the next 30 years improving his chronometer and was awarded a good deal of money as a result. What do ships use to navigate today?
Back in the day
George III ascended the throne at the age of 22, during the Seven Years' War. The war had put England in financial distress, and George supported raising funds through taxation of the American colonies. This policy proved disastrous for him, as it provoked the American Revolution and led him to be blamed in part for losing the colonies. Later in life, George's mental health declined, and his son acted as regent after 1811. It has been suggested that he suffered from what hereditary disease?
Born on a day like today
Pearl was an American country comedienne, born Sarah Colley in Centerville, Tennessee. One of the Grand Ole Opry's most iconic performers, she appeared on the show for more than 50 years, performing routines that gently poked fun at rural Southern culture. Outfitted in styleless "down home" dresses and a hat with a price tag that dangled over its brim, she also appeared regularly on the television show Hee Haw from 1969 to 1991. On whom was the Minnie Pearl character based?
