4.2 K run
Just a short race I did in Scotland last week, at a conference in Glasgow. It was the morning after a whisky tasting session… I wonder how much effect that had on participant numbers! (Not whiskey, as I was reminded - maybe that’s because I’ve spent too much time in Ireland!)
In case you’re wondering why this race was 4.2 km (it’s an obscure reason, so you might well be): 4.2 Kelvin (4.2 K) is the boiling point of liquid helium. Until recently, almost all superconductors have used liquid helium as the coolant, in order to reach the temperatures at which they operate. Having a 4.2 km race is, apparently, a tradition at this applied superconductivity conference. That’s definitely a geeky physicists in-joke… Still, it was fitting I suppose in Glasgow, seeing as we ran the race in Kelvin park, not far from the statue of William Thomson (aka Lord Kelvin).
