Episode 181 - RAYDAC

from Advent of Computing

In 1947 Raytheon signed a contract to make their first computer. It would be their last... at least for many many years. The fruits of this contract was RAYDAC. Early digital computers were odd, to say the least. And RAYDAC distinguishes itself. From zig-zag delay lines to hunting tapes to freon cooling, it truly is a unique machine.

This Impact Studios production is a collaboration with the Governor family, UTS Faculty of Law and Jumbunna Institute for Indigenous Education and Research.The Last Outlaws teamKatherine Biber - UTS Law Professor and Chief InvestigatorAunty Loretta Parsley - Great-granddaughter of Jimmy Governor and the Governor Family Historian Leroy Parsons - Governor descendant, Narrator and Co-WriterKaitlyn Sawrey - Host, Writer and Senior ProducerFrank Lopez - Writer, Managing Next Generation Energy Systems Cambridge University Background Stakeholders working with energy systems have to make complex decisions formulated from risk-based assessments about the future. The move towards more renewables in our energy systems complicates matters even further, requiring the development of an integrated power grid and continuous and steady transformation of the UK power system. Network flows must be managed reliably under uncertain demands, uncertain supply, emerging network technologies and possible failures and, further, prices in related markets can be highly volatile. Mathematicians working with engineers and economists, can make significant contributions to address such issues, by helping to develop fit-for-purpose models for next generation energy systems. These interdisciplinary approaches are looking to address a range of associated problems, including modelling, prediction, simulation, control, market and mechanism design and optimisation.
