Before the implementation of standardized time zones in the United States, every town pretty much decided what time it was on their own. This wasn’t that big of a deal when you had to walk everywhere, but it created some major problems as communication and transportation got faster in the 19th century: imagine creating an accurate train schedule when the time of day is slightly different at every stop. In today’s episode, we’re taking a look at some old transportation maps—from coach lines to railroads to air travel—and reflecting on the ways our conception of time has evolved alongside these industries. Join us on a journey through time and space in this punctual new #brattlecast.
