Graph showing velocity calculations (Figure 20 from publication on Relativity)

Lantern slide showing graph related to relativity likely used to accompany a lecture.

The original graph was published in Frederick William Lanchester's book "Relativity; an elementary explanation of the space-time relations as established by Minkowski and a discussion of gravitational theory based thereon" as figure 20.

Figure 20 is a plotting of vis viva mass as a function of velocity. The results of Kaufmann's determinations (K) and Sir J. J. Thomson's calculations (Th) are given for comparison.
