“The generalized theory of relativity has furnished still more remarkable results. This considers not only uniform but also accelerated motion. In particular, it is based on the impossibility of distinguishing an acceleration from the gravitation or other force which produces it. Three consequences of the theory may be mentioned of which two have been confirmed while the third is still on trial: (1) It gives a correct explanation of the residual motion of forty-three seconds of arc per century of the perihelion of Mercury. (2) It predicts the deviation which a ray of light from a star should experience on passing near a large gravitating body, the sun, namely, 1".7. On Newton's corpuscular theory this should be only half as great. As a result of the measurements of the photographs of the eclipse of 1921 the number found was much nearer to the prediction of Einstein, and was inversely proportional to the distance from the center of the sun, in further confirmation of the theory. (3) The theory predicts a displacement of the solar spectral lines, and it seems that this prediction is also verified.”
“If an American, because his skin is dark, cannot eat lunch in a restaurant open to the public, if he cannot send his children to the best public school available, if he cannot vote for the public officials who represent him, if, in short, he cannot enjoy the full and free life which all of us want, then who among us would be content to have the color of his skin changed and stand in his place? Who among us would then be content with the counsels of patience and delay?”
“Why is this happening to me? Why am I having such a difficult time? One answer is that life is supposed to be difficult! It’s what enables us to grow. Remember, earth is not heaven!”
“But the princess had never seen the beautiful expression of her eyes; the expression that
came into them when she was not thinking of herself. As is the case with everyone, her face
assumed an affected, unnatural, ugly expression as soon as she looked in the looking glass.”
“If only [people] understood that every thought is both false and true! False by one-
sidenedness resulting from man's inability to embrace the whole truth, and true as an
expression of one fact of human endeavor.”
“Unhappy it is, though, to reflect that a brother's sword has been sheathed in a brother's breast and that the once-happy plains of America are either to be drenched with blood or inhabited by slaves. Sad alternative! But can a virtuous man hesitate in his choice?”
