Jeans, James Hopwood, Sir, 1877-1946 · Cambridge [Eng.] : University Press · leaf 143
l be an equation ofthe form ^ = i+se, where 6 is the aggregate volume of the number of molecules which occur ina unit volume of the gas, and s is a numerical multiplier. But it is at onceclear that the value of s will depend not only on the shape but also on theorientation of the molecules. Cleaily… … Fig. 46 c. the lines of force, as in fig. 46 a, and will be least when the needles lie atright angles to this position, as in fig. 46 h. Or to put the matter in anotherway, a piece of dielectric in which the molecules are needle-shaped andparallel will exhibit different values of K according as the…
