Making Waves

Voorkant
American Inst. of Physics, 1995 - 210 pagina's
From one of the most imaginative and daring scientific minds of this or any century comes a thoughtful, almost intimate account of a personal journey through his momentous discoveries - achievements that have changed the face of medicine, industry, even weapons. Nobel laureate Charles H. Townes, inventor of the maser and co-inventor, with Arthur Schawlow, of the laser, takes us on a behind-the-scenes tour of his unique - and startlingly productive and creative - way of working. Along the way, you'll learn about how Townes came upon his surprising findings and how he managed to avoid obstacles in his path. Townes introduces us to the wonders of the universe, from the submicroscopic, most minute - the workings of atoms and the even smaller particles that make them up - to the vast outer reaches of space. His tour takes us along paths Townes pioneered: quantum electronics, microwave spectroscopy and the frontiers of our galaxy where he explored the dark, rarefied clouds of gas and dust where new stars form. Recognizing that some of the most revolutionary recent scientific theories about how the universe emerged come close to religious thought, these accessible essays conclude with a uniquely personal coda in which Townes suggests that science and religion occupy the same terrain.

Over de auteur (1995)

Charles Townes was born in Greenville, South Carolina, and attended Furman University. After graduate study at Duke University and the California Institute of Technology, he spent the years from 1939 to 1947 at the Bell Telephone Laboratories designing radar-controlled bombing systems. Townes then joined the physics department of Columbia University. In 1951, while sitting on a park bench, the idea for the maser (microwave amplification by stimulated emission of radiation) occurred to him as a way to produce high-intensity microwaves. In 1953 the first maser became operational. In a maser, ammonia (NH3) molecules are raised to an excited vibrational state and then fed into a resonant cavity, where (as in a laser) they stimulated part of the spectrum. "Atomic clocks" of great accuracy are based on this concept, and solid-state maser amplifiers are used in radioastronomy. In 1964 Townes and two Soviet laser pioneers, Aleksander Prokhorov and Nikolai Basov, shared the Nobel Prize. Since 1966 Townes has been at the University of California, Berkeley.
