Page 19 - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it is compelled by forces to change that state.
Page 20 - Every particle of matter in the universe attracts every other particle with a force that varies inversely as the square of the distance between them and directly as the product of their masses.
Page 23 - It was shown, in connection with the study of the theory of the dynamo, that whenever a conductor is moved in a magnetic field so as to cut lines of force, an EMF is induced in the conductor.
Page 172 - W= /,sin(61«H-a1)+^//sm(&J^+^)+^/"etc. dtSince the square of any polynomial is equal to the su'm of the squares of each term separately plus twice the product of each term by every other term...
Page 66 - o, A, and d are constants for a given capacitor, the capacitance is a constant independent of the charge on the capacitor, and is directly proportional to the area of the plates and inversely proportional to their separation.

Page 32 - OF RESULTS In this paper the following results have been obtained. (i) It has been shown how the perturbation series for the many-body problem may be expressed as a sum of terms each of which is associated with a certain diagram. (ii) This has been reduced to a series of terms (linked-cluster expansion) corresponding to linked diagrams. (iii) A series has been obtained for the energy shift AE due to the interaction, each term of which is associated with a certain 'vacuum
