The Origin and Development of the Quantum Theory: Being the Nobel Prize Address Delivered Before the Royal Swedish Academy of Sciences at Stockholm, 2 June, 1920 (Classic Reprint)

Excerpt from The Origin and Development of the Quantum TheoryMy task this day is to present an address dealing with the subjects of my publications. I feel I can best discharge this duty, the significance of which is deeply impressed upon me by my debt of gratitude to the generous founder of this Institute, by attempting to sketch in outline the history of the origin of the Quantum Theory and to give a brief account of the development of this theory and its influence on the Physics of the present day.When I recall the days of twenty years ago, when the conception of the physical quantum of 'action' was first beginning to disentangle itself from the surrounding mass of available experimental facts, and when I look back upon the long and tortuous road which finally led to its disclosure, this development strikes me at times as a new illustration of Goethe's saying, that 'man errs, so long as he is striving'. And all the mental effort of an assiduous investigator must indeed appear vain and hopeless, if he does not occasionally run across striking facts which form incontrovertible proof of the truth he seeks, and show him that after all he has moved at least one step nearer to his objective. The pursuit of a goal, the brightness of which is undimmed by initial failure, is an indispensable condition, though by no means a guarantee, of final success.In my own case such a goal has been for many years the solution of the question of the distribution of energy in the normal spectrum of radiant heat.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
