Spent the day in Cambridge today. Found a Harvard trig point.
Small but sweet.
Was stumped by this mathematical clock. I can work some of them out - and obviously I know the answers - but 1, 3, 11...?
And the treat of the day was discovering the Smoot measurement. Harvard Bridge is 364.4 Smoots +/- an ear.
Smoots are marked all the way across the bridge.
How cool is that?
