Visualizing proper-time in Special Relativity
Roberto B. Salgado
Abstract
We present a new visualization of the proper-time elapsed along an observer's worldline. By supplementing worldlines with light clocks, the measurement of space-time intervals is reduced to the "counting of ticks." The resulting space-time diagrams are pedagogically attractive because they emphasize the relativistic view that "time is what is measured by an observer's clock."
