Briggsian

Briggsian refers to something related to Henry Briggs, an English mathematician. He is most famous for his work with logarithms. Briggs developed the common logarithm, also known as the Briggian logarithm or decimal logarithm, which uses base 10. This was a significant improvement over natural logarithms for practical calculation. He created extensive tables of these logarithms, which were invaluable tools for scientists, engineers, and navigators for centuries. His efforts greatly simplified complex multiplication and division into simpler addition and subtraction. Briggs also made contributions to the development of coordinate geometry and the calculation of pi. The term Briggsian is therefore used to denote his specific contributions, particularly the base-10 logarithm system and the logarithmic tables he compiled.
