Quite a lot as it turns out.
(Disclosure: I was invited to attend both talks in return for writing this short review)
Whilst both speakers were looked at technology from war (and other base instincts) they were separated by over 150 years. Peter Nowak (Sex, Bombs and Burgers: How War, Porn and Fast Food Created Technology as we Know it) looked at mostly post World War II innovations that were now commonplace, and Rachel Hewitt (Map of a Nation: A Biography of the Ordnance Survey) looked back to the 1790’s and the birth of the Ordinance Survey.
Peter’s book is an enjoyable romp through just about every gadget, meal and (ahem) alternative entertainment you’ve ever heard of (and a couple you probably haven’t) and how they can trace their roots back to either military research projects or the companies that produced them. If anything was missing, it was a sense of grand narrative. A couple times during both Andrew’s interview and the subsequent Q&A he was pressed on the ethical questions raised but never really answered them.
Peter did make one prediction that robotics are now, where the PC was 20 years ago and that in 20 years time robotics would be as ubiquitous as the computer is now. Not quite sure I agree with that, there are lots of deeper sociological issues with robots such as challenges to our sense of self, issues over robot rights (robot is, after all, literally serf labor, in Polish), and the sheer creepiness of human-like robot forms.
A very interesting comment from the floor suggested a fourth base instinct to go with war, food & sex which was our innate curiosity and desire for the next shiny shiny thing. Whilst some of these companies can trace their origins to military activity, their current innovations and particularly their speed of innovation, are driven more by consumer competition rather than warmongering.
By contrast, Rachel gave a fascinating and engaging talk about the origins of the Ordinance Survey and the people involved. It was quite clear that whilst the maps were commissioned to provide Britain with a military advantage in the event of invasion, the cultural impact of having a unified map of the country was also very important to those early cartographers. I was especially taken by the notion that William Mudge encouraged alternative uses of the original map series.
Rachel also noted that the early trig points were located at the sites of the national chain of warning Beacons (as these were on natural sight lines around the coast). Their rudimentary theodolites frequently needed flares to provide them with sufficient light to focus upon, and these flares naturally gave rise to the very real fear of imminent invasion!
In the equally entertaining and informative Q&A that followed, Rachel explored the cultural importance of maps and the role that the Ordinance Survey played in the cultural life of Britain, national rivalries with France, technology advances, and the location of the original Base Line (now mostly under Heathrow Airport).
A great evening all round!
