Studying events that happen quickly has always been challenging, especially before motion picture cameras were invented. In the late 1800s, Eadweard Muybridge began using a series of cameras, activated in sequence, to record motion on film. The individual pictures could then be viewed as a flip-book "movie."

Race Horse Bet

At one point, two men at a race track bet a large sum of money on whether a galloping race horse had at least one foot on the ground at all times. To settle this argument, Muybridge set up a row of twenty cameras, each triggered by the running horse, to capture the motion of the horse's legs.

Which side of the bet would you put your money on? and why?
