Developed influential mathematical concepts, including Simpson's rule for approximating definite integrals, and made significant contributions to the field of calculus.
Thomas Simpson, a British mathematician and inventor, is best known for his eponymous Simpsons rule, a method for approximating definite integrals. Although the rule had been discovered 100 years earlier by Johannes Kepler, Simpson's work popularized it and earned him recognition in the mathematical community.
Born on August 20, 1710, in Sutton Cheney, Leicestershire, Simpson was the son of a weaver. Despite lacking formal education, he taught himself mathematics and developed a passion for the subject. At the age of 19, he married a 50-year-old widow with two children, and they had no children of their own.
Simpson's career as a mathematician began when he moved to London at the age of 25. He supported his family by weaving during the day and teaching mathematics at night. In 1743, he became a teacher of mathematics at the Royal Military Academy, Woolwich, a position he held for many years. Simpson was elected a Fellow of the Royal Society in 1745 and a foreign member of the Royal Swedish Academy of Sciences in 1758.
Simpson's most notable work includes his treatises on probability and annuities. His book, The Nature and Laws of Chance, was based on the work of Abraham de Moivre, and he acknowledged de Moivre's contributions in the text. Simpson's goal was to present complex mathematical concepts in a clear and concise manner, making them accessible to a wider audience.
The Simpsons rule, also known as Kepler's Barrel Rule in German, is a method for approximating definite integrals. The rule states that the value of a definite integral can be approximated by the sum of the values of the function at equidistant points. Simpson's work on this rule has had a lasting impact on mathematics, and it remains an essential tool for mathematicians and scientists today.
Despite his significant contributions to mathematics, Simpson's personal life was not without controversy. He was known to have dabbled in astrology and divination, and he even claimed to have raised a devil from a girl, causing fits. This incident led to him and his wife fleeing to Derby.
Simpson died on May 14, 1761, in Market Bosworth, and was buried in Sutton Cheney. A plaque inside the church commemorates his life and achievements. His legacy as a mathematician and inventor continues to inspire future generations of scholars.
"Tho' it neither wants Matter nor Elegance to recommend it, yet the Price must, I am sensible, have put it out of the Power of many to purchase it." - Thomas Simpson, The Nature and Laws of Chance
Thomas Simpson's work laid the foundation for future mathematicians and scientists. His contributions to the field of mathematics have had a lasting impact, and his rule remains an essential tool in many scientific disciplines. Simpson's legacy serves as a reminder of the power of self-education and perseverance in achieving success.
