This article presents an explication of the references to the history of the calculus in the first few pages of Chapter 4 of Deleuze's _Difference and Repetition_. In those pages, Deleuze uses anachronistic readings of the calculus to explain his theory of ontogenesis, beginning with the differential, dx, that is strictly nothing by itself but that establishes singular points in relation to other differentials. He builds from the differential to power series, showing a corresponding process of determination in the ontogenesis (...) as the mathematics moves from derivative to the so-called original function.

This article asks what is creative about the act of programming. Observing that in most programming contexts, each line of code is written with a specific end in mind, it would seem as though there is little room for creativity, as the ends constrain the choices of means. However, there are many features of coding languages that open up creative possibilities. Object-oriented coding environments purport to make programming more about structures that humans might work with and less about features of (...) computers, and other innovative coding techniques, such as RTTI design, suggest that there may be no limit to the creative possibilities of code.

This article explores the role of touch in the human-computer interface, suggesting that touch is strangely completed by vision and abandons its usual haptic quality. The interface relies heavily on touch, but that touch never touches what it reaches for, instead presenting a dynamic of pointing rather than touching. The paper goes on to consider how this unusual mode of touch alters the way this sense operates in the computing context, possibly shaping cognition in relation to the interface.

This article explores the question of what number is, demonstrating parallels between the Deleuzian notion of the differential as a dynamic moment of number and the intuitionist definition of number as a choice sequence. One conclusion offers a theory of mathematical progress, and suggests that this theory might be extended to domains outside of mathematics.
