Billions of people now use computers. Most of them are just users of desktop computers and notebooks and they relied on software prepared by computer scientists who need to know computer programming. Not many know programming rely on a mathematical sequence known as Bernoulli numbers which was discovered by Ada Lovelace in the nineteenth century!
Ada Lovelace met Charles Babbage in 1833.

Ada Lovelace has emerged as the most popular role model in a day dedicated to celebrating women working in the fields of science and technology.
So far, 2,239 people around the world have posted blogs, videos and podcasts online nominating their heroines.
Additionally, events were held in London, Copenhagen, Dresden, Montreal and Brazil to mark the day, named after Ms Lovelace, held on 24 March.
Ada Lovelace worked with mathematician Charles Babbage in the 1800s.
Mr Babbage's invention, the Analytical Engine, formed the basis of modern computing.
Ada Lovelace is therefore credited with writing the world's first computer program when she came up with a way of using the machine, which was never actually built, to calculate a mathematical sequence.
