Nothing is created by coincidence, rather there is reason and necessity for everything. Leukippus, 5th Century BC. De Omnibus Dubitandum. Claes Johnson on Mathematics and Science. This is a continuation of an earlier post on The World as Computation starting out as follows:. Horace Lamb had also made gentle fun of the theory of circulation by exploiting the theological overtones of Kelvin's theorem.
In his Rouse Ball Lecture of , titled "The Evolution of Mathematical Physics", Lamb had said of perfect fluid theory that "this theory cannot tell us why an aeeroplane needs power for its propulsion; nor, indeed, can it tell us how the aeroplane obtains its sustenation, unless by assuming certain circumstances to have been established at the Creation which, in all reverence, we find it hard to believe" circulation.
In the last edition of his Hydrodynamics, in , Lamb returned to the problem of the origin of circulation and of understanding how it resulted from a smooth flow being established at the trailing edge of a wing. Bloor describes how English wit outmaneuvers German technocracy, in what can be seen as an anticipation of the upcoming war. Germany lost the war but German circulation theory survived in the absence of anything better. Upplagd av Claes Johnson kl.

Inasmuch as Brahmagupta used some of the same examples as Diophantus, we see again the likelihood of Greek influence in India — or the possibility that they both made use of a common source, possibly from Babylonia. The Mathematical Secret of Flight , The Regius Professorships are "royal" professorships, being created by the reigning monarch. However, in it was still possible for Weyl to defend his theory in the following way. The Wright brothers had made their first flight in and by the time War broke out in August considerable advances had been made but aeronautical theory was still in its infancy.
