As noted back in June of this year, scale bars are not only useful for understanding size in space, but also helpful for adding context to time. Though less of a scale bar and more of a frame of reference, the video below offers a fun look at the overlap between historical events. We often think of historical events discretely, without also connecting them with what was happening elsewhere in the world. Doing so can lead to some surprises, like the overlap between Woolly Mammoths and the Great Pyramids, or that the University of Oxford is older than the Aztec Empire. And did Pablo Picasso get a chance to listen to Dark Side of the Moon? Find out below.
