1 00:00:16,500 --> 00:00:22,859 Hello everyone, my name is Sandra González and today we'll be talking about Ada Lovelace. 2 00:00:22,859 --> 00:00:29,980 Ada Lovelace was a British mathematician and she is considered to be the first computer programmer. 3 00:00:29,980 --> 00:00:40,740 Ada Lovelace was born the 10th of December 1815 in London and she died on November the 27th in 1852. 4 00:00:40,740 --> 00:00:49,039 Her full name is Ada King, Countess of Lovelace, but her original name was Augusta Ada Byron, 5 00:00:49,039 --> 00:00:51,640 mostly known as Lady Byron. 6 00:00:51,640 --> 00:00:59,420 Her parents were Lord Byron, the famous poet, and Annabella Milbank Byron, who legally separated 7 00:00:59,420 --> 00:01:02,219 two months after her birth. 8 00:01:02,219 --> 00:01:07,859 After that, his father left England, and Ada never knew him personally. 9 00:01:07,859 --> 00:01:12,079 He died in Greece when Ada was 8 years old. 10 00:01:12,079 --> 00:01:18,359 In order to neutralize the dangerous mental tendencies of Ada's father, her mother insisted 11 00:01:18,359 --> 00:01:24,159 on music, French, mathematics in her daughter's studies. 12 00:01:24,159 --> 00:01:27,859 This last subject particularly appealed to Ada. 13 00:01:27,859 --> 00:01:33,459 In those days, there were no places for girls in the United Kingdom's universities. 14 00:01:33,459 --> 00:01:39,079 Nevertheless, Ada was educated to a high level by private tutors. 15 00:01:39,079 --> 00:01:46,040 However, Ada suffered long periods of time in poor health, during her childhood and later. 16 00:01:46,040 --> 00:01:51,859 In 1833, Ada Lovelace met the mathematician Charles Babbage. 17 00:01:51,859 --> 00:01:57,340 Babbage was a Lucasian professor of mathematics at the University of Cambridge, 18 00:01:57,340 --> 00:02:03,060 a position once held by Isaac Newton or Stephen Hawking later on. 19 00:02:03,060 --> 00:02:08,240 He had designed a calculating machine called the Difference Engine. 20 00:02:08,240 --> 00:02:14,379 Lovelace was inspired by the prototype of the Difference Engine and became Babbage's friend. 21 00:02:14,379 --> 00:02:21,219 She was also a friend of one of the finest female mathematicians of her time, Mary Somerville. 22 00:02:21,219 --> 00:02:27,900 She discussed modern mathematics with Mary and set other higher-level mathematical problems. 23 00:02:27,900 --> 00:02:36,240 The 8th of July, 1835, Ada married William King, at that time she was 19 years old 24 00:02:36,240 --> 00:02:42,240 and they had three children together, between 1836 and 1839 25 00:02:42,800 --> 00:02:50,860 By 1842, Babbage had a new project in mind, a much more advanced machine, the analytical engine 26 00:02:50,860 --> 00:02:59,300 In 1843, Lovelace translated a French paper that Luigi Manebra, Italian mathematician, 27 00:02:59,300 --> 00:03:02,000 wrote about the analytical engine. 28 00:03:02,000 --> 00:03:03,900 She also added some notes. 29 00:03:03,900 --> 00:03:09,180 Her notes were three times more extensive than the original work. 30 00:03:09,180 --> 00:03:15,099 Lovelace realized that the analytical engine could carry out an extensive sequence of mathematical 31 00:03:15,099 --> 00:03:16,099 operations. 32 00:03:16,099 --> 00:03:22,379 She wrote an example of one sequence, how to calculate Bernoulli numbers. 33 00:03:22,379 --> 00:03:27,219 It is regarded by computer historians as the first computer program. 34 00:03:27,219 --> 00:03:38,419 She even speculated that the analytical engine could be used to perform operations on other things besides numbers, such as musical notes. 35 00:03:38,419 --> 00:03:41,659 However, not everything went according to plan. 36 00:03:41,659 --> 00:03:48,659 Ada Lovelace became increasingly unwell after she wrote her translation and died young. 37 00:03:48,659 --> 00:03:56,360 Charles Babbage ran into financial problems, which meant he never built a working computer. 38 00:03:56,360 --> 00:04:05,360 Ada Lovelace died, probably of uterine cancer, at the age of 36, on the 27th of November, 1852. 39 00:04:05,360 --> 00:04:10,860 Ada asked to be buried beside Lord Byron in Nottingham. 40 00:04:10,860 --> 00:04:14,860 Her work wasn't recognized until a century after her death. 41 00:04:14,860 --> 00:04:21,860 90 years later, Alan Turing read his work about analytical engines and could have been inspired by it. 42 00:04:21,860 --> 00:04:25,860 Alan Turing was the man who created the first computer. 43 00:04:25,860 --> 00:04:33,860 The concept of a machine that could be more than a calculator to compose music, for example, began with Lovelace. 44 00:04:33,860 --> 00:04:41,860 We can say that Ada Lovelace is the mother of modern computing and that Charles Babbage is the father. 45 00:04:41,860 --> 00:04:52,860 However, we don't know if the child died in infancy or if it lived in some kind of suspended animation until it was rediscovered by Alan Turing. 46 00:04:52,860 --> 00:05:02,860 Ada Lovelace Day is an international celebration of the achievements of women in science, technology, engineering and maths. 47 00:05:02,860 --> 00:05:07,860 It is celebrated every year on the second Tuesday of October. 48 00:05:07,860 --> 00:05:11,860 There is also a computer language called Ada. 49 00:05:11,860 --> 00:05:19,860 The Ada programming language was designed for critical systems where security and reliability are essential, 50 00:05:19,860 --> 00:05:25,860 such as air traffic control, satellites or commercial aircraft. 51 00:05:25,860 --> 00:05:30,860 Ada Lovelace represents hope, innovation and progress. 52 00:05:30,860 --> 00:05:40,939 Thank you all for your attention, I hope you enjoyed and I'll see you in the next video.
