1872 One day, in a hotel in California, there was a heated argument between Stanford and Cohen: did the horses all land when running? Stanford thinks that a running horse's hoof is empty at the moment of jumping; On the other hand, Cohen thinks that horses always touch the ground when running. No one could convince anyone of the result of the argument, so the usual bet method was adopted to solve it. They hired an excellent horse trainer to judge, however, it is difficult for the referee to judge who is right and who is wrong. This is normal, because it is really difficult to see how the fast-running horseshoe moves with the human eye alone.

When Edward Muybridge, a good friend of the referee, learned about it, he said he could give it a try. He placed 24 cameras on one side of the runway in succession, and their lenses were all aimed at the runway. On the other side of the runway, he ran into 24 stakes, each with a rope tied to it. These lines cross the runway and are tied to the shutter of each camera opposite.

When everything was ready, McBride brought a beautiful horse and let it run from one end of the runway to the other. When the horse ran through this area, the 24-pole lead tripped in turn, and the shutters of 24 cameras were pulled in turn, taking 24 photos. McBride cut these photos in order. Every two adjacent photos have little difference in action, and they form a continuous photo belt. According to this set of photos, the referee finally saw that when the horse was running, there was always a hoof on the ground and it wouldn't fly, so Cohen won. It is reasonable to say that the story should end here, but this bet and its strange judgment method have aroused great interest. Mcbride showed people a photo tape with images of galloping horses over and over again. Once, someone unconsciously pulled the photo tape quickly, and as a result, a strange scene appeared in front of him: the static horse in each photo was folded into a moving horse, and it was "alive"!
