. The anatomy of science. Science. 64 THE ANATOMY OF SCIENCE occurs one centimeter to the right of the knot O, and about two minutes and a half from the beginning of the experiment. The whole dia- gram is a map of the loca- tion of the beads in space and time. A heavy pendulum with an ink brush attached to it traces its own space-time diagram upon a sheet of paper moving uniformly beneath it (Figure 12). Both of these figures record only motion in a single line, and this is all we can do with a plane diagram. But if we employ a solid model, using the two horizontal directions for position in Space-Time Map of space, and again the verti- a Pendulum i t i* /• •!• cal directions tor position in time, we could record motions upon a plane surface, for example, balls upon a billiard table. The sun and planets move nearly in a single plane, and I have attempted to construct a model showing the space-time map of the sun and the first three planets, a photograph of. Figure 12.
