Turing centenary

The Alan Turing Year was celebrated worldwide in 2012. Multiple Turing events were held in several cities. I attended quite a few of those events myself and audio recorded the speeches. My objective here is to compare and contrast claims that computer professionals, historians, and others have made about Turing and our field.

28 January 2021

Many Turing scholars share a dualistic outlook on science and technology, distinguishing between non-causal (abstract) objects and causal objects. This outlook stands in stark contrast with Turing's monistic thinking and his answer to what a Turing machine meant to him in 1948. ......

Chapter 1 of Turing Tales

The first chapter of my 2016 book Turing Tales is made available here. I explain my methodological stance on the history of computer science, and introduce the topic of "conflations," which I believe is key to understanding the history of science and technology.
