- J. J. Thomson and The Electron: 1897–1899: An Introduction (PDF)
This being the 100th anniversary of J. J. Thomson’s discovery of the electron, the October 1897 paper in which he presented his case that cathode rays are streams of subatomic “corpuscles” is attracting a great deal of attention. Viewed from 100 years later, this paper stands out as the starting point for the research into the structure of the atom that has dominated 20th-century science.
- Yerba Buena Gardens (Wikipedia)
Yerba Buena Gardens is the name for two blocks of public parks located between Third and Fourth, Mission and Folsom Streets in downtown San Francisco, California. The first block bordered by Mission and Howard Streets was opened on October 11, 1993. The second block, between Howard and Folsom Streets, was opened in 1998, with a dedication to Martin Luther King Jr. by Mayor Willie Brown. A pedestrian bridge over Howard Street connects the two blocks, sitting on top of part of the Moscone Center convention center. The Yerba Buena Gardens were planned and built as the final centerpiece of the Yerba Buena Redevelopment Area which includes the Yerba Buena Center for the Arts. Yerba Buena Gardens Conservancy operates, manages, programs, and elevates the property on behalf of the City and County of San Francisco.
- Cathode Rays (en.wikisource.org)
THE experiments discussed in this paper were undertaken in the hope of gaining some information as to the nature of the Cathode Rays. The most diverse opinions are held as to these rays; according to the almost unanimous opinion of German physicists they are due to some process in the æther to which—inasmuch as in a uniform magnetic field their course is circular and not rectilinear—no phenomenon hitherto observed is analogous: another view of these rays is that, so far from being wholly ætherial, they are in fact wholly material, and that they mark the paths of particles of matter charged with negative electricity. It would seem at first sight that it ought not to be difficult to discriminate between views so different, yet experience shows that this is the case, as amongst the physicists who have most deeply studied the subject can be found supporters of either theory.
