A graph of the Bernoulli Numbers by French mathematician Simon Plouffe, posted today in honor of Ada Lovelace, born this day nearly two hundred years ago to poet Lord Byron and mathematician Anne Isabella Milbanke, the “princess of parallelograms,” who school Ada intensively in mathematics in order to disuade her father’s moody and rebellious nature from taking hold of her. Ada wrote a scientific paper in 1843 that anticipated the development of computer software, artificial intelligence and computer music, and she devised a method of using punchcards to calculate Bernoulli numbers, thus becoming the first computer programmer. She is known today as the Patron Saint of Female Hackers.
