G. I. Taylor, or Geoffrey Ingram Taylor, was a prominent British physicist and engineer known for his contributions to fluid mechanics. Born in 1886, he made significant advancements in understanding the behavior of fluids, particularly in turbulent flow and the dynamics of bubbles and drops. His work laid the foundation for many modern applications in engineering and environmental science. Taylor was also a key figure in the development of the Taylor series, a mathematical concept that approximates functions using polynomials. He served as a professor at Cambridge University and was elected a Fellow of the Royal Society in 1927, recognizing his influential research and discoveries in the field.
