Ada Lovelace Day

Monday, Oct. 12th 2015 at 10am to Wednesday, Oct. 14th 2015 at 12pm

Kiritimati, Line Islands, Kiribati

This is a 50 hour event despite being only a day long, it starts at the start on the 13th of October on Kiritimati Island, which is 14 hours ahead of GMT and finishes at the end of the 13th of October on Howland Island which is 12 hours behind GMT. The reason it is on 13/10/2015 is because they decided that most people would be free in October.

The Analytical Engine

The Analytical Engine was a hypothetical computer that she wrote code for which could calculate a series of numbers called Bernoulli Numbers. She also realised that it may be able to process other things such as music. I have quoted her below.

"The Analytical Engine might act upon other things besides number, were objects found whose mutual fundamental relations could be expressed by those of the abstract science of operations, and which should be also susceptible of adaptations to the action of the operating notation and mechanism of the engine...

Supposing, for instance, that the fundamental relations of pitched sounds in the science of harmony and of musical composition were susceptible of such expression and adaptations, the engine might compose elaborate and scientific pieces of music of any degree of complexity or extent."

Charles Babbage Analytical Engine


In 1990 Allan G. Bromely proposed that she had only done 1 of the 9 programs prepared for the Analytical Engine, and that the other 8 had been made by her partner, Charles Babbage. These programs were allegedly prepared between 3 and 7 years earlier, however there is evidence that Lovelace was tricked into publishing the files by Babbage, and she did not deliberately be dishonest. Another piece of evidence supporting her legitimacy is that once Babbage had given her the files, she then edit them making herself the first "de-bugger" and that she did know how to code.
