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 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
