Throughout her life, Lovelace was strongly interested in scientific developments and fads of the day, including phrenology[1] and mesmerism.[2] After her work with Babbage, Lovelace continued to work on other projects.

In 1844 She commented to a friend Woronzow Greig about her desire to create a mathematical model for how the brain gives rise to thoughts
and nerves to feelings ("a calculus of the nervous system").[3] She never achieved this, however.In part, her interest in the brain came from a long-running pre-occupation.
In the same year, she wrote a review of a paper by Baron Karl von Reichenbach,Researches on Magnetism, but this was not published and does not appear to have progressed past the first draft.[4]
In 1851 A year before her cancer struck, she wrote to her mother mentioning "certain productions" she was working on regarding the relation of maths and music.[5]
In June 1833 Lovelace first met Babbage
In 1842–1843 Lovelace translated the Italian mathematician Luigi Menabrea's article on Babbage's newest proposed machine, the Analytical Engine.
On 12 August 1851 Ada Lovelace wrote to Benjamin Woolley asking him to be her executor, though this letter did not give him the necessary legal authority. [6]
