IN: Augusta Ada King-Noel, Countess of Lovelace (nee Byron; 10 December 1815 - 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and published the first algorithm intended to be carried out by such a machine. As a result, she is sometimes regarded as the first to recognise the full potential of a "computing machine" and the first computer programmer. Ada Lovelace was the only legitimate child of the poet Lord Byron, and his wife Anne Isabella "Annabella" Milbanke, Lady Wentworth.

In her notes, Lovelace emphasised the difference between the Analytical Engine and previous calculating machines, particularly its ability to be programmed to solve problems of any complexity. She realised the potential of the device extended far beyond mere number crunching. In her notes, she wrote:  [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.  This analysis was an important development from previous ideas about the capabilities of computing devices and anticipated the implications of modern computing one hundred years before they were realised. Walter Isaacson ascribes Lovelace's insight regarding the application of computing to any process based on logical symbols to an observation about textiles: "When she saw some mechanical looms that used punchcards to direct the weaving of beautiful patterns, it reminded her of how Babbage's engine used punched cards to make calculations." This insight is seen as significant by writers such as Betty Toole and Benjamin Woolley, as well as the programmer John Graham-Cumming, whose project Plan 28 has the aim of constructing the first complete Analytical Engine.  According to the historian of computing and Babbage specialist Doron Swade:  Ada saw something that Babbage in some sense failed to see. In Babbage's world his engines were bound by number...What Lovelace saw--what Ada Byron saw--was that number could represent entities other than quantity. So once you had a machine for manipulating numbers, if those numbers represented other things, letters, musical notes, then the machine could manipulate symbols of which number was one instance, according to rules. It is this fundamental transition from a machine which is a number cruncher to a machine for manipulating symbols according to rules that is the fundamental transition from calculation to computation--to general-purpose computation--and looking back from the present high ground of modern computing, if we are looking and sifting history for that transition, then that transition was made explicitly by Ada in that 1843 paper.

what did Ada see that others didn't see

OUT: number could represent entities other than quantity.


IN: Bill "Bojangles" Robinson (May 25, 1878 - November 25, 1949) was an American tap dancer and actor, the best known and most highly paid African-American entertainer in the first half of the twentieth century. His long career mirrored changes in American entertainment tastes and technology. He started in the age of minstrel shows and moved to vaudeville, Broadway, the recording industry, Hollywood, radio, and television.

The idea for bringing a black dancer to Fox to star with Temple in The Little Colonel was actually first proposed by Fox head Winfield Sheehan after a discussion with D. W. Griffith. Sheehan set his sights on Robinson but, unsure of his ability as an actor, arranged for a contract that was void if Robinson failed the dramatic test. Robinson passed the test and was brought in to both star with Temple and to teach her tap dancing. They quickly hit it off, as Temple recounted years later:  Robinson walked a step ahead of us, but when he noticed me hurrying to catch up, he shortened his stride to accommodate mine. I kept reaching up for his hand, but he hadn't looked down and seemed unaware. Fannie called his attention to what I was doing, so he stopped short, bent low over me, his eyes wide and rows of brilliant teeth showing in a wide smile. When he took my hand in his, it felt large and cool. For a few moments, we continued walking in silence. "Can I call you Uncle Billy?" I asked. "Why sure you can", he replied... "But then I get to call you darlin.'" It was a deal. From then on, whenever we walked together it was hand in hand, and I was always his "darlin.'"  Temple had already appeared in five films released in 1934, and had performed a tap routine with James Dunn in Stand Up and Cheer! After Robinson was signed by 20th Century Fox, it was decided that he would perform his famous stair dance with Temple. While Robinson liked the idea, he quickly realized that he could not teach his complex stair dance to a seven-year-old in the few days permitted by the shooting schedule. Instead, he taught Temple to kick the riser (face) of each stairstep with her toe. After watching her practice his choreography, Robinson modified his routine to mimic her movements, so that it appeared on film that she was imitating his steps. The sequence was the highlight of the film.  Robinson and Temple became the first interracial dance partners in Hollywood history. The scene was controversial for its time, and was cut out in the south along with all other scenes showing the two making physical contact. Temple and Robinson appeared in four films together: The Little Colonel, The Littlest Rebel, Rebecca of Sunnybrook Farm and Just Around the Corner.  Robinson and Temple became close friends as a result of his dance coaching and acting with her. Robinson carried pictures of Temple with him wherever he traveled, and Temple considered him a lifelong friend, saying in an interview "Bill Robinson treated me as an equal, which was very important to me. He didn't talk down to me, like to a little girl. And I liked people like that. And Bill Robinson was the best of all."

Was this the only interactions they had?
