A figure showing K-negative scattering and interaction. A K-negative meson scatters on one proton and then interacts with another proton to form a sigma-positive and a pi-negative. The sigma positive decays to a pi-positive and a neutron. Photograph taken October 29, 1956. Bubble Chamber-112B. See also XBD201210-01202.TIF

Forty high school science teachers joined the Laboratory staff this summer in a teacher-training program. The program was initiated to stimulate the teachers so that they might improve and bring up to date their teaching curricula. Left to right, Dr. Wilson Powell(Physics Research Group Leader), Bill Baum (Alhambra High School, Martinez), and Anthony Rinaldi (Burbank Junior High School, Berkeley). Dr. Powell explains to the teachers a template showing the way a pi meson looks in the propane bubble chamber. Morgue 1959-56 (P-1) [Photographer: Donald Cooksey]

NARA & DVIDS Public Domain Archive

The objects in this collection are from The U.S. National Archives and Defense Visual Information Distribution Service. The U.S. National Archives and Records Administration (NARA) was established in 1934 by President Franklin Roosevelt. NARA keeps those Federal records that are judged to have continuing value—about 2 to 5 percent of those generated in any given year. There are approximately 10 billion pages of textual records; 12 million maps, charts, and architectural and engineering drawings; 25 million still photographs and graphics; 24 million aerial photographs; 300,000 reels of motion picture film; 400,000 video and sound recordings; and 133 terabytes of electronic data. The Defense Visual Information Distribution Service provides a connection between world media and the American military personnel serving at home and abroad. All of these materials are preserved because they are important to the workings of Government, have long-term research worth, or provide information of value to citizens.

Disclaimer: A work of the U.S. National Archives and DVIDS is "a work prepared by an officer or employee" of the federal government "as part of that person's official duties."
