Analytical Society

The Analytical Society was a small group in early 19th‑century Britain that pushed for Leibnizian (analytical) notation in calculus, instead of the traditional Newtonian notation with dots over variables. Newton’s system had become the standard in Britain, but many mathematicians believed Leibniz’s notation was clearer, especially for functions of several variables.

Origins and purpose
The society was formed at Cambridge around 1812–1813 by Charles Babbage, John Herschel, and George Peacock. It grew from concern that British mathematics was stuck in old fluxional methods and that continental ideas were not being taught. The aim was to promote notation and methods that came from Leibniz rather than Newton.

Disbanding and lasting influence
The group effectively dissolved by 1814 when most of the original members had graduated. Yet its influence continued to ripple through Cambridge and beyond. In 1816 Peacock and Herschel translated Sylvestre Lacroix’s textbook using Leibnizian notation, a project begun by Babbage. In 1817, Leibnizian symbols began appearing in Cambridge exams, and by 1819 the new approach faced some criticism from authorities.

Spread of the new notation
Encouraged by younger Cambridge scholars, Leibnizian notation began to spread more widely. William Whewell used the new notation in 1820 examinations, and Peacock did so again in 1821, helping to establish the change. By the 1830s, Leibniz’s notation had become widely adopted in Britain and was used alongside the old Newtonian dots.

Publications and examples
The Analytical Society supported important publications that showcased the new method. Peacock wrote a collection of examples applying the differential and integral calculus, Herschel contributed on finite differences, and Whewell published An Elementary Treatise on Mechanics (1819), a standard textbook that used the new notation. John Ains later published work applying Leibnizian calculus to physical problems.

Legacy
Although short‑lived, the Analytical Society played a crucial role in introducing and spreading Leibnizian calculus in Britain. Its efforts helped move British mathematics away from purely Newtonian notation and toward a more continental, analytical approach that influenced teaching and research for years to come.
