Ada Lovelace Biography

Augusta Ada byron Lovelace was born on 10 December 1815. Ada Lovelace died on 27 November 1852. Ada Lovelace was an English mathematician and writer. In Lovelace mathematician biography we see that she proposed the general machinery computer machine analysis work of Charles Babbage. She was the first person to realize that machines have applications beyond pure computing, and published the first algorithm designed to be executed by such machines. Therefore, she is usually considered the first computer programmer.

Ada Lovelace was the only daughter of the poet Lord Lovelace and Mrs. Lovelace. All of Lord Lovelace’s other children were born out of wedlock with other women. One month after Ada was born, Lovelace separated from his wife and left England four months later. When Ada was eight years old, her father died in Greece. Her mother was still suffering and promoted Ada's interest in mathematics and logic to prevent her from developing what her father thought was insanity. We will learn more about her in Ada Lovelace biography.

Ada Lovelace: Mathematician

In Lovelace mathematician biography, we will learn about her adulthood, her field of interests, and her education and work. Her educational and social achievements brought her into contact with scientists such as Andrew Cross, Charles Babbage, Sir David Brewster, Charles Wheatstone, Michael Faraday, and the writer Charles Dickens. People are the object of his later studies. Ada described her method as "the science of poetry". As a teenager, her talent for mathematics allowed her to establish a long-term working relationship and friendship with British mathematician Charles Babbage, who is known as the "father of computers." She was particularly interested in Babbage's work on analytical engines. Lovelace first met him in June 1833 through their mutual friend and personal mentor Mary Somerville. 

Between 1842 and 1843, Ada translated an article on computer engines by Italian military engineer Luigi Menabrea and added a set of elaborate notes. Lovelace notes were important in the early history of computers. They contain what many people think of as the first computer program, an algorithm designed to be executed by a machine. Other historians opposed this view, pointing out that Babbage's personal notes of 1836 contained the first program of the engine. She also developed a vision for the ability of computers to go beyond simple calculations or processing numbers, and many others, including Babbage himself, only focused on these capabilities. Her "poetic science" mentality prompted her to ask questions about analysis engines to examine how individuals and societies relate to technology as a collaborative tool. She died of uterine cancer in 1852 at the age of 36.

Adulthood

In Ada Lovelace biography we will see that she became close friends with her mentor Mary Somerville, who introduced her to Charles Babbage in 1833. She has great respect and love for Somerville, and they have communicated for many years. Other acquaintances include scientist Andrew Cross, Sir David Brewster, Charles Wheatstone, Michael Faraday, and writer Charles Dickens. She appeared in court at the age of 17, and became a popular beauty of the season, due to her "intelligence." In 1834, Ada became a frequent visitor to the court and began participating in various activities. She danced a lot, attracted a lot of people, and most describe her as elegant, although Byron's friend John Hobhouse describes her as "a big, rough-skinned young woman. Ada made it clear to Hobhouse that she did not like him, possibly due to her mother's influence, which led her to dislike her friends. his father. This first impression did not last, and then they became friends.

Education 

In Lovelace mathematician biography we see that her education began in 1832, when she was 17 years old, her mathematics ability began to appear, and her interest in mathematics dominated most of her adult life. Her mother was obsessed with eliminating Ada’s alleged insanity, which is one of the reasons why Ada had been educated in mathematics since she was a child. She received private education in mathematics and science from William Flanders, William King, and Mary Somerville, a famous scientific researcher, and writer in the 19th century. In the 1840s, the mathematician Augustus De Morgan gave her great help in his mathematical research, including research on advanced calculus topics, including "Bernoulli numbers". In a letter to Ada, De Morgan suggested that Ada's mathematics ability could make her an original mathematics researcher, perhaps a top-notch level.

Work

During her life, Lovelace was very interested in scientific development and contemporary fashion, including phrenology and hypnotism. After working with Babbage, Lovelace continued to work on other projects. In 1844, she told her friend Woronzow Greig that she wanted to create a mathematical model to illustrate how the brain produces thoughts and the nerves produce feelings. However, it never achieved this goal. To some extent, her interest in the brain stems from the long-term care she inherited from her mother on her "latent" insanity. As part of her research on the project, she visited electrical engineer Andrew Crosse in 1844 to learn how to conduct electrical experiments. In the same year, she commented on Baron Karl von Reichenbach's article on Reichenbach's article, but the article was not published and did not appear to exceed the first draft. In 1851, the year before contracting cancer, she wrote to his mother, mentioning that he was studying certain works on the relationship between mathematics and music.

Babbage and Ada Lovelace 

In 1840, Babbage was invited to conduct a seminar on his analytical engine at the University of Turin. Luigi Menabrea, a young Italian engineer and future Prime Minister of Italy, transcribed Babbage's speech into French, which was subsequently published in the "Geneva World Library" in October 1842. Babbage's friend Charles Wheatstone commissioned Ada Lovelace to translate the Menabrea document into English. He then expanded the paper with annotations, which were added to the translation. With the help of Babbage, Ada Lovelace had been doing this for most of the year. These notes are longer than Menabreya's article and were published in Taylor's Scientific Memoirs in September 1843 under the acronym AAL. Ada Lovelace's 4,444 notes are marked alphabetically from A to G. In note G, describe the analysis engine algorithm used to calculate the Bernoulli number. It is considered to be the first public algorithm specifically designed for implementation on a computer, so Ada Lovelace is often cited as the first computer programmer. The engine was never completed, so its program was never tested.

Perception of Computing Devices

In her notes, Ada Lovelace emphasized the difference between analysis engines and early computers, especially their ability to solve any complex problems through programming. She realized that the potential of the device goes far beyond pure digital processing. This analysis is an important development of the early ideas about the function of computing devices and predicted the impact of modern computing a hundred years before the realization of modern computing. Walter Isaacson attributed Ada’s insights about applying calculations to any process based on logical symbols to observations of textiles: “When he saw some power looms that use punch cards to guide the weaving of beautiful patterns, it reminded him how Babbage’s engine uses punch cards for calculations.

"This knowledge is regarded as important by writers such as Betty Toole and Benjamin Woolley, and programmer John Graham-Cumming. The goal of her Plan 28 project was to build the first complete analysis engine. In Babbage's world, their engines are connected by numbers but Lovelace sees that numbers can represent entities other than numbers. So once you have a machine to manipulate numbers, if these numbers represent other things, letters, musical notes, then the machine can manipulate the numbers as symbols of instances according to the rules. It is this fundamental change from a machine that is a digital shredder to a machine that processes symbols according to rules. It is the fundamental change from calculus to calculations and then to general calculations. They were searching and shifting through history to find this transition, and Ada made this transition explicitly in that 1843 article.
