Professor Jed Z. Buchwald,
How the Ether Spawned the Micro-World
Tirsdag, den 19. november 2002, kl. 19.45
Throughout most of the 19th century the atom and
molecule were not customary presences in the calculations and laboratories of
many physicists. Although most were convinced of atomic reality, many were not,
and in any case the vast bulk of work in physics had little to do with the
All of this had changed dramatically by 1910, for
microphysics was by then at the very foundation of theoretical and experimental
research. How did the micro-world acquire this central role, one that it has
played ever since?
Was it propelled to prominence by a series of stunning
experimental discoveries (the electron, X-rays, and radioactivity) that occurred
between 1895 and 1900? Or did it first emerge on paper, only subsequently
acquiring a new life in such laboratories as the Cavendish? Why did the world of
the atom displace the world of the ether during the 1890s?
