Propagation Quotes

The general equations are next applied to the case of a magnetic disturbance propagated through a non-conductive field, and it is shown that the only disturbances which can be so propagated are those which are transverse to the direction of propagation, and that the velocity of propagation is the velocity v, found from experiments such as those of Weber, which expresses the number of electrostatic units of electricity which are contained in one electromagnetic unit.

The application of force alone, without support based on a spiritual concept, can never bring about the destruction of an idea or arrest the propagation of it, unless one is ready and able to ruthlessly to exterminate the last upholders of that idea even to a man, and also wipe out any tradition which it may tend to leave behind.
