Memorizing and regurgitating are not science. Real science is a constant investigation of the unknown.

Sie findet den Ausdruck als gemeinsame Verehrung eines Ideals, des Ideals objektiver Wahrheit, Klarheit und Genauigkeit. Sie besteht aus dem Glauben, daß Verehrtes erst in weiter, vielleicht unendlich weiter Zukunft erreichbar sei. Aus der Lobpreisung sich seinem Dienste aufzuopfern. Aus einem bestimmten Heroenkult und einer bestimmten Tradition. Dies wäre der Grundton der gemeinsamen Stimmung, in der sich das naturwissenschaftliche Denkkollektiv auslebt. Kein Eingeweihter wird behapten, das wissenschaftliche Denken sei gefühlsfrei.

. . .a scientific theory is just a mathematical model we make to describe our observations: it exists only in our minds. So it is meaningless to ask: which is real, "real" or "imaginary" time? It is simply a matter of which is the more useful description.

Scientific theories are tested every time someone makes an observation or conducts an experiment, so it is misleading to think of science as an edifice, built on foundations. Rather, scientific knowledge is more like a web. The difference couldn’t be more crucial. A tall edifice can collapse – if the foundations upon which it was built turn out to be shaky. But a web can be torn in several parts without causing the collapse of the whole. The damaged threads can be patiently replaced and re-connected with the rest – and the whole web can become stronger, and more intricate.

Science Fiction is a safe, fertile arena in which to rehearse the potential scientific facts of tomorrow

New scientific ideas never spring from a communal body, however organized, but rather from the head of an individually inspired researcher who struggles with his problems in lonely thought and unites all his thought on one single point which is his whole world for the moment.
