Von Richthofen, Einstein and the AGA Estimating Achievement from Fame
Von Richthofen, Einstein and the AGA Estimating achievement from fame Every schoolboy has heard of Einstein; fewer have heard of Antoine Becquerel; almost nobody has heard of Nils Dalén. Yet they all won Nobel Prizes for Physics. Can we gauge a scientist’s achievements by his or her fame? If so, how? And how do fighter pilots help? Mikhail Simkin and Vwani Roychowdhury look for the linkages. “It was a famous victory.” We instinctively rank the had published. However, in 2001–2002 popular French achievements of great men and women by how famous TV presenters Igor and Grichka Bogdanoff published they are. But is instinct enough? And how exactly does a great man’s fame relate to the greatness of his achieve- ment? Some achievements are easy to quantify. Such is the case with fighter pilots of the First World War. Their achievements can be easily measured and ranked, in terms of their victories – the number of enemy planes they shot down. These aces achieved varying degrees of fame, which have lasted down to the internet age. A few years ago we compared1 the fame of First World War fighter pilot aces (measured in Google hits) with their achievement (measured in victories); and we found that We can estimate fame grows exponentially with achievement. fame from Google; Is the same true in other areas of excellence? Bagrow et al. have studied the relationship between can this tell us 2 achievement and fame for physicists . The relationship Manfred von Richthofen (in cockpit) with members of his so- about actual they found was linear. -

Title: the Distribution of an Illustrated Timeline Wall Chart and Teacher's Guide of 20Fh Century Physics
REPORT NSF GRANT #PHY-98143318 Title: The Distribution of an Illustrated Timeline Wall Chart and Teacher’s Guide of 20fhCentury Physics DOE Patent Clearance Granted December 26,2000 Principal Investigator, Brian Schwartz, The American Physical Society 1 Physics Ellipse College Park, MD 20740 301-209-3223 [email protected] BACKGROUND The American Physi a1 Society s part of its centennial celebration in March of 1999 decided to develop a timeline wall chart on the history of 20thcentury physics. This resulted in eleven consecutive posters, which when mounted side by side, create a %foot mural. The timeline exhibits and describes the millstones of physics in images and words. The timeline functions as a chronology, a work of art, a permanent open textbook, and a gigantic photo album covering a hundred years in the life of the community of physicists and the existence of the American Physical Society . Each of the eleven posters begins with a brief essay that places a major scientific achievement of the decade in its historical context. Large portraits of the essays’ subjects include youthful photographs of Marie Curie, Albert Einstein, and Richard Feynman among others, to help put a face on science. Below the essays, a total of over 130 individual discoveries and inventions, explained in dated text boxes with accompanying images, form the backbone of the timeline. For ease of comprehension, this wealth of material is organized into five color- coded story lines the stretch horizontally across the hundred years of the 20th century. The five story lines are: Cosmic Scale, relate the story of astrophysics and cosmology; Human Scale, refers to the physics of the more familiar distances from the global to the microscopic; Atomic Scale, focuses on the submicroscopic This report was prepared as an account of work sponsored by an agency of the United States Government. -

Recollections and Reconstructions
@ ? Editor's Note: The Society's Nuclear Pioneer Citationfor 1977 goes not to an individual but to a distinguished group of individuals: those who took part in the epochal “ChicagoPile―experiment of Dec. 2, 1942, which produced thefirst successful atomicpile chain reaction. The 42 members ofthe Chicago Pilegroup are listed on page 591. One ofthose named, Harold M. Agnew, now Directorofthe Los Alamos Scient@flc Laboratory, is the Nuclear Pioneer Lecturerfor the 24th Annual Meeting. The guidingforce behind the Chicago Pile experiment was Enrico Fermi, recipient of the Nuclear Pioneer Citation of 1963. In the artick which follows, Laura Fermi recreates the excitement and mystery that surrounded the work ofher husband's research team in the early 1940s in Chicago. @.
