To this day I remember Chris Friedrichs (warning: UBC's security certificate for this site has expired) telling us that now that we were graduate students, we would appreciate being able to be in the library right up to Christmas, while undergraduates scattered off to home and hearth.
Nowadays, the UBC libraries are closed during Saturnalia.
Which is why the second technical appendix for December postblogging appears first. It has nothing to do with my losing precious research time exploring the 40 or so "Esquisse pour servire a l'histoire du Rome" inserted, apparently randomly and by an unknown hand, into the map pocket at the back of the library's 1876 Desjardins. In the spirit of the season....
That said, even without having covered the Fortune article yet, it is pretty clear that refrigeration needs a post, especially as I am going to link it to the Battle of North Cape. And by "needs a post," I mean, "needs multiple doctoral dissertations in economic, social, cultural and gender history." But that ain't gonna happen. So instead here is a discussion of the history of explosives, which is important because the transition to modern explosives required storage in temperature and humidity-controlled conditions that, in turn, led to state security-related investment in HVAC technology ahead of the rise of the cold chain logistics that has so clearly transformed our lives without being much investigated, although Jonathan Reese's book looks like an interesting first step.
So: the link to the Battle of North Cape? North Cape is the somewhat grandiose title for Bruce Fraser's successful mousetrapping of the battlecruiser KMS Scharnhorst on 26 December 1943. By keeping fast capital ships in Norwegian ports threatening the Russian convoys, the Germans were able to stretch Allied naval resources, with knock-on effects extending from the Eastern Front to the Pacific, until, as must inevitably happen, they ran out of capital ships. Losing Scharnhorst --somehow-- was both inevitable and painful for the Germans, and an incremental step towards victory for the Allies.
That's the top down view. Bottom up, it comes down to steam conditions, fire control solutions (1,2,3), volume of fire and progress in organic chemistry. (Noting that I got Robert Neville confused with James H. McGraw, Jr.)
The steam condition thing is interesting. Scharnhorst was very fast for its size due to operating with 850F steam, and, like its heavy cruiser contemporaries, suffered repeated machinery breakdowns because of it. So is it possible that the fatal blow that slowed it down at North Cape was inflicted internally, by steel failing in the wet blast? It's a wild-assed theory that I raise because of its salience to issues that do matter. (Here's Antonio Bonomi promoting it.)
For fire control, we can notice that it was Bruce Fraser who headed the team that designed the Admiralty Fire Control Table, and Bruce Fraser who won the Battle of North Cape. There's a lot going on here in the nascent history of computing, and I am not going to dissent from the common analysis that the radar stuff matters more than a weird little pneumatic computer, but there it is.
For volume of fire, I link to my posting on Jutland, the battle that the Royal Navy lost by letting institutional imperatives trump safety considerations, and the historical profession muffed by missing the well-publicised cause of the battlecruiser losses in favour of talking about "technological decline." Take what you will from that. The point is that Duke of York's ammunition chain was designed to make it mechanically impossible for a deflagration to propagate unchecked from the turret to the magazines. This was the right thing to do: even the most vigorous lip service to safety is still lip service. It is unfortunate that the resulting loss of fire opportunities keeps getting laid off on "unreliability," as though safety precautions were unmanly or something. Slow we are to learn.
So, ammunition storage is the previously-mentioned entre to the issue of the extremely rapid propagation of powered HVAC up and down the cold chain and of air conditioning on parallel lines. This takes us back to the introduction of the first 'modern,' artificial explosive, nitrocellulose, the explosive that was also a plastic! I have talked about modern explosives, indirectly before. Specifically, I notice that I supplied the footnote, but not the discussion! As I move towards the climax of the munitions war, so it is time to get that stuff on the internet.
