Talk at the Computational Foundry, Swansea University, 24th April 2024. https://alandix.com/academic/talks/Swansea-song-April-2024/ This talk was my last formal act as Director of the Computational Foundry, before retiring from Swansea University at the end of April 2024. It was the last part in a research afternoon of the School of Mathematics and Computer Science, during which there were talks by other members of the school including a wonderful potted history of Maths and CS in the University and the Computational Foundry by John Tucker and Matt Jones. This talk is a summary (partial) of more personal research through my time at Swansea, some in collaboration with others across the university, some with those external to Swansea, and some more individual. The talk used a number of web-based prototypes and systems that I've developed, many as weekend projects, to look at areas including AI, digital humanities and heritage, qualitative-quantitative reasoning, statistics and maths education, physical prototyping and UX tools. The talk included work inspired by teaching, consultancy and other real-world problems, but almost always also including a strong theoretical dimension. This reflects my personal background, as the son of a carpenter, but where mathematics was my academic 'first love' -- always seeking out ways in which practical making and fundamental knowledge interact. A theme that runs through many of the examples is the way in which many if the things that were completed while at Swansea had roots before, and also things I started here will continue on the future. And now I look forward to the coming years; although my employment at Swansea has ended, I will continue to collaborate with many in the University, both those I have met since being in Swansea and those I know before.
