No one, who knows what the difficulties are, now believes that the crisis of physics is likely to be resolved by any simple trick or modification of … - John Desmond Bernal

The progress in science has been anything but uniform in time and place. ...In the course of time the centres of scientific activity have been continually displaced, usually following rather than leading the migration of the centres of commercial and industrial activity. Babylonia, Egypt, and India have all been the foci of ancient science. Greece became their common heir, and there the rational basis... was first worked out. There was little place for science in Rome and none in the barbarian kingdoms of western Europe. The heritage of Greece returned to the East from whence it had come. In Syria, Persia, and India, even in... China, new breaths... came... in a brilliant synthesis under the banner of Islam. There they underwent a development which... was to give rise to... modern science.

As the scene of life would be more the cold emptiness of space than the warm, dense atmosphere of planets, the advantage of containing no organic material at all, so as to be independent of both these conditions, would be increasingly felt.

In science men have learned consciously to subordinate themselves to a common purpose without losing the individuality of their achievements. Each one knows that his work depends on that of his predecessors and colleagues, and that it can only reach its fruition through the work of his successors. In science men collaborate not because they are forced to by superior authority or because they blindly follow some chosen leader, but because they realize that only in this willing collaboration can each man find his goal.
