“But you can wake a man only if he is really asleep; no effort that you may make will produce any effect upon him if he is merely pretending sleep. That”
“The arbitrary and meaningless tests to decide black from Coloured or Coloured from white often resulted in tragic cases where members of the same family were classified differently, all depending on whether one child had a lighter or darker complexion. Where one was allowed to live and work could rest on such absurd distinctions as the curl of one’s hair or the size of one’s lips.”
“Don't rush in order to have things done early. Be prepared before you set off. That's the rule. However, this does not mean that you keep delaying the time for beginning. You must begin by all means! Go, get prepared!”
“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.”
