Ada's Echo
註釋Augusta Ada King, Countess of Lovelace (1815-1852), known commonly as Ada Lovelace, is considered the first computer programmer. Her collaborations with English mathematician Charles Babbage on his Analytical Engine led her to create the first computer algorithm and to ruminate on future technological applications of computing systems other than mathematical calculations. Her translation of mathematician Luigi Menabrea's article on Babbage's Engine from Italian included her own expansive notes which set out out an algorithm for the Analytical Engine to compute the Bernoulli numbers. Lovelace was the only legitimate child of English poet Lord Byron, and it was her mother Annabella Milbanke who had insisted on her mathematical training from childhood. Ada Lovelace Day is celebrated yearly on October 16. Kelly Wellman's artist book Ada's Echo incorporates handwritten excerpts from Lovelace's correspondence to Babbage, along with companion text written by Wellman, in which the computer is represented by the Greek mythological figure Echo on whose voice Ada Lovelace's innovations are carried to the present: "The valleys filled with silicon and I was forced to learn a new language. Now I speak in bits and bytes. Strings of zeros and ones. I navigate a new topography." With layers of translucent papers, Wellman overlays visuals of contemporary computer chips, Ada Lovelace's equations, fabric patterns (Lovelace had compared the Analytical Engine to a loom), with Lovelace's own words (in script) on the outermost layer, bringing her voice to the fore.--http://library.udel.edu.
