9: 29.12 Definitions

… ►This result admits the following electrostatic interpretation: Given three point masses fixed at $t=0$, $t=1$, and $t=k^{-2}$ with positive charges $\rho +\frac{1}{4}$, $\sigma +\frac{1}{4}$, and $\tau +\frac{1}{4}$, respectively, and $n$ movable point masses at $t_1,t_2,\mathrm{\dots },t_n$ arranged according to (29.12.12) with unit positive charges, the equilibrium position is attained when $t_j={\xi }_j$ for $j=1,2,\mathrm{\dots },n$.
