Scottish mathematician and surveyor

Scottish mathematician and surveyor
Scottish mathematician known for Stirling’s formula and pioneering work in analysis and probability.
James Stirling was born in 1692 in Garden, Scotland. He became one of the leading mathematicians of the 18th century, renowned for his contributions to analysis and infinite series. His publication "Methodus differentialis" introduced what is now known as Stirling’s approximation for factorials, a fundamental tool in probability and statistics. Stirling also studied the properties of the gamma function and laid groundwork for modern treatises on mathematical analysis. Beyond pure mathematics, he worked as a surveyor in Jamaica, applying his skills to practical engineering and mapping projects. His rigorous methods and elegant proofs influenced contemporaries and successors, including Euler and Bernoulli. Stirling died in 1770, and his formula remains a cornerstone in mathematical education and research.

Scottish engineer invented the radar
Sir Robert Watson-Watt was a Scottish engineer and pioneer of radar technology, instrumental in Britain's air defense during World War II.
Born in Brechin, Scotland in 1892, Robert Watson-Watt trained as a meteorologist and radio engineer. In the mid-1930s, he led research at the British Air Ministry to develop radio detection and ranging, giving rise to the first operational radar system. His Chain Home network provided early warning of incoming aircraft, playing a decisive role in the Battle of Britain. After the war, Watson-Watt advocated for applications of radio waves in meteorology and astronomy. He later served as a professor at the University of Aberdeen. His groundbreaking work laid the foundation for modern air traffic control and remote sensing. He died on December 5, 1973.
