English mathematician and philosopher

English mathematician and philosopher
English mathematician and logician whose development of Boolean algebra laid the groundwork for modern digital computing.
George Boole (1815–1864) was an English mathematician, philosopher, and logician. He introduced Boolean algebra, a formal system of logic that serves as the foundation for binary computing. Boole's 1854 work 'An Investigation of the Laws of Thought' applied algebraic methods to logical reasoning. His theories later became central to the design of digital circuits and computer programming. Boole's interdisciplinary approach bridged mathematics and philosophy, influencing fields from artificial intelligence to information theory.

American astronomer and academic

American astronomer and academic
American astronomer and academic who pioneered the study of the Milky Way's structure and established the Sun's place in the galaxy.
He directed the Harvard College Observatory for over three decades, from 1921 to 1952. Shapley used Cepheid variable stars to reveal that the Milky Way was far larger than previously believed. He determined that the Sun lies well outside the galaxy's central region, reshaping our cosmic perspective. A passionate educator, he lectured widely and authored books to bring astronomy to the public. His mentorship of young astronomers helped build the field of galactic research throughout the 20th century. He died in 1972, remembered as a visionary in our understanding of the Milky Way.
