Julian Schwinger citations

Julian Seymour Schwinger est un physicien américain. Il formule la théorie de la renormalisation et décrit un phénomène de paire d'électron-positron connu sous le nom d'effet Schwinger. Il partage avec Sin-Itiro Tomonaga et Richard Feynman le prix Nobel de physique de 1965 « pour leurs travaux fondamentaux en électrodynamique quantique, ce qui a amené de profondes conséquences à la physique des particules élémentaires ».

Julian Schwinger: Citations en anglais

“Is the purpose of theoretical physics to be no more than a cataloging of all the things that can happen when particles interact with each other and separate? Or is it to be an understanding at a deeper level in which there are things that are not directly observable (as the underlying quantized fields are) but in terms of which we shall have a more fundamental understanding?”

Quantum Mechanics - Symbolism of Atomic Measurements (2001) p. 24 f.

“If my history lesson has done nothing else, it should have reminded you that, during any given period in the evolving history of physics, the prevailing, main line, climate of opinion was likely as not to be wrong, as seen in the light of later developments. And yet, in those earlier times, with relatively few individuals involved, change did occur, but slowly… What is fundamentally different in the present day situation in high energy physics is that large numbers of workers are involved, with corresponding pressures to conformity and resistance to any deflection in direction of the main stream, and that the time scale of one scientific generation is much too long for the rapid pace of experimental discovery. I also have a secret fear that new generations may not necessarily have the opportunity to become familiar with dissident ideas.”

“Perhaps the most important contribution to science that the Royal Society has made in its three centuries of existence is its early role in publishing Newton's masterful account of his discoveries.”
