Analytical Society
The Analytical Society was a group of individuals in early-19th-century Britain whose aim was to promote the use of Leibnizian notation for differentiation in calculus as opposed to the Newton notation for differentiation. The latter system came into being in the 18th century as a convention of Sir Isaac Newton, and was in use throughout Great Britain. According to a mathematical historian:
The Society was first envisioned by Charles Babbage as a parody on the debate of whether Bible texts should be annotated, with Babbage having the notion that his textbook by Sylvestre Lacroix was without need for interpretation once translated. Its membership originally consisted of a group of Cambridge students led by Babbage and including Edward Bromhead.
Robert Woodhouse had brought the Leibniz notation to England with his book Principles of Analytical Calculation in 1803. While Newton's notation was unsuitable for a function of several variables, Woodhouse showed, for instance, how to find the total differential of where φ is a function of p and q:
