Reading the Economist last night, I came across the following rather strange advertisement.
It’s an ad for a watch, the “C1 Concord” apparently, not at all uncommon in the Economist (although it is rather on the ugly side…) Looking closer, though, there’s unmistakably some maths in the background.
Anyone know what the maths is about? It looks pretty plausible — there are some things looking like long exact sequences in there, as well as some fundamental groups, and power series for exponentials. Best of all there’s some text lower down in the ad – “What other watch has a formula for the ultimate construction?” I’m guessing they found a real mathematician to write some pretty looking maths for them — I wonder if they realised they were being asked to write “a formula for the ultimate construction”?
