Sometimes, if you're lucky as a historian, you find a bit of evidence which illuminates a big idea. That happened to me this week in the Pepys Library at Magdalene College, Cambridge.

The thought uppermost in my mind was how odd it is that non-scientists think of science as being about certainties and absolute truth. Whereas scientists are actually quite tentative - they simply try to arrive at the best fit between the experimental findings so far and a general principle.

The manuscript I found was a ship's journal kept by a 17th Century English sea captain, who had offered to carry some state-of-the-art scientific equipment on a voyage to the west coast of Africa and back - two new pendulum clocks.

[ Not a bad article, but not great either. I think the author was unclear in places and not quite in front of the argument, as I see it.
