  • Newly Opened Correspondence Illuminates Einstein's Personal Life
    CENTER FOR HISTORY OF PHYSICS NEWSLETTER Vol. XXXVIII, Number 2 Fall 2006 One Physics Ellipse, College Park, MD 20740-3843, Tel. 301-209-3165 Newly Opened Correspondence Illuminates Einstein’s Personal Life By David C. Cassidy, Hofstra University, with special thanks to Diana Kormos Buchwald, Einstein Papers Project he Albert Einstein Archives at the Hebrew University of T Jerusalem recently opened a large collection of Einstein’s personal correspondence from the period 1912 until his death in 1955. The collection consists of nearly 1,400 items. Among them are about 300 letters and cards written by Einstein, pri- marily to his second wife Elsa Einstein, and some 130 letters Einstein received from his closest family members. The col- lection had been in the possession of Einstein’s step-daughter, Margot Einstein, who deposited it with the Hebrew University of Jerusalem with the stipulation that it remain closed for twen- ty years following her death, which occurred on July 8, 1986. The Archives released the materials to public viewing on July 10, 2006. On the same day Princeton University Press released volume 10 of The Collected Papers of Albert Einstein, con- taining 148 items from the collection through December 1920, along with other newly available correspondence. Later items will appear in future volumes. “These letters”, write the Ein- stein editors, “provide the reader with substantial new source material for the study of Einstein’s personal life and the rela- tionships with his closest family members and friends.” H.

By Daniel Kleppner, Forum Chair At the “April” 2010 meeting (held in February to be joint with the American Association of Physics Teachers),the FHP and the Forum on Industrial and Applied Physics sponsored “The Laser: Its History and Impact on Precision Measurement” (Ses- sion X4). The speakers were Joseph Giordmaine, Frederico Capas- so, and John Hall. Dr. Giordmaine, completed his Ph.D. with Charles Townes at Columbia University, on the use of the maser amplifier in planetary astronomy. Later at Bell Labs he worked with ruby lasers, harmonic generation, and nonlinear optics, and is now retired vice president of physical science research at NEC Labs. Dr. Capasso pioneered band structure engineering through molecular beam epitaxy, resulting in electronic and photonic devices dominated by mesoscopic scale quantum effects, includ- ing the quantum cascade laser. Dr. Hall, currently a NIST Senior Fellow Emeritus and Fellow at the Joint Institute for Laboratory Astrophysics (JILA), won the 2005 Nobel Prize in physics (with Theodor W. Hnsh) for his work on laser-based precision spectros- copy and the optical comb technique. oseph Giordmaine traced the pioneering advances made in the laser during the years 1960-1964, in his Jtalk “The Laser: Historical Perspectives and Impact on Precision Measurements.” The seminal concept, stimu- Fig. 1.

Did you know that Albert Einstein was one of the scientists who worked on the more theoretical side of the laser or that the word laser, itself, is an acronym short for light amplification by stimulated emission of radiation? In 50 years, lasers have come a long way. From the first masers, the original pre-cursor to light-amplified radiation to the eventual practical use of lasers in supermarket checkout counters, home entertainment systems, and surveyors’ tools. This the History Explorer Meet Our Museum Podcast and in this month’s episode we speak with Hal Wallace, curator of the Electricity Collections, here at the Museum of American History to discuss the development of the laser and what it’s meant to American culture and history.

  • The Development of Nonlinear Science£
    The development of nonlinear science£ Alwyn Scott Department of Mathematics University of Arizona Tucson, Arizona USA August 11, 2005 Abstract Research activities in nonlinear science over the past three centuries are reviewed, paying particular attention to the explosive growth of interest in chaos, solitons, and reaction-diffusion phenomena that occurred during the 1970s and considering whether this explosion was an example of a “sci- entific revolution” or Gestalt-like “paradigm shift” as proposed by Thomas Kuhn in the 1962. The broad structure of modern nonlinear science is sketched and details of developments in several areas of nonlinear research are presented, including cosmology, theories of matter, quantum theory, chemistry and biochemistry, solid-state physics, electronics, optics, hydro- dynamics, geophysics, economics, biophysics and neuroscience. It is con- cluded that the emergence of modern nonlinear science as a collective in- terdisciplinary activity was a Kuhnian paradigm shift which has emerged from diverse areas of science in response to the steady growth of comput- ing power over the past four decades and the accumulation of knowledge about nonlinear methods, which eventually broke through the barriers of balkanization. Implications of these perspectives for twentyfirst-century research in biophysics and in neuroscience are discussed. PACS: 01.65.+g, 01.70.+w, 05.45.-a £ Copyright ­c 2005 by Alwyn C. Scott.
