Colin Maclaurin was a Scottish mathematician who was born in Kilmaden, Scotland, in February 1698 and died in Edinburgh on June 14, 1746. MacLaughlin was one of the most influential British mathematicians of the 18th century.
McLaughlin is the son of a pastor. He lost his father when he was six months old and his mother when he was nine years old. Raised by his uncle. My uncle is also a pastor. McLaughlin was a "child prodigy". In order to become a priest, he was admitted to the University of Glasgow to study theology at the age of 11. However, he became interested in mathematics soon after entering school and switched to mathematics a year later. Obtained a master's degree at the age of 17 and gave a wonderful public defense for his thesis on the work of gravity; at the age of 19, he served as a professor of mathematics at the University of Aberdeen and chaired the mathematics work at Marishell College; two years later he was elected Member of the Royal Society; engaged in research in Paris from 1722 to 1726. In 1724, he won funds from the French Academy of Sciences for writing an outstanding paper on object collision. After returning to China, he served as a professor at the University of Edinburgh.
In 1719, Maclaurin met Newton when he visited London and became Newton's disciple ever since. In 1724, due to Newton's strong recommendation, he continued to receive a professorship. When McLaughlin was 21 years old, he published his first important book, "Structural Geometry". In this book, he described some new and ingenious methods of making conic sections, and incisively discussed the various properties of conic sections and higher-order plane curves. "The Theory of Flows" written in 1742 uses Taylor series as a basic tool and is the first book to provide a logical and systematic explanation of Newton's flow method. The purpose of this book is to provide a geometric framework for Newton's flow method in response to the attacks on Newton's calculus principles by Archbishop Baker and others. He demonstrated the theory of fluidity with skillful geometric methods and exhaustive methods. He also used series as a method of integrating, and independently from Cauchy, he gave an integral criterion for the convergence of infinite series in geometric form. He obtained the famous Maclaurin series expansion in mathematical analysis and proved it using the undetermined coefficient method.
