Photocopy Of Photograph (original Print Located In LBNL Photo Lab Collection)
A photocopier (also called copier or copy machine, and formerly Xerox machine, the generic trademark) is a machine that makes copies of documents and other visual images onto paper or plastic film quickly and cheaply. Most modern photocopiers use a technology called ''xerography'', a dry process that uses electrostatic charges on a light-sensitive photoreceptor to first attract and then transfer toner particles (a powder) onto paper in the form of an image. The toner is then fused onto the paper using heat, pressure, or a combination of both. Copiers can also use other technologies, such as inkjet printer, inkjet, but xerography is standard for office copying. Commercial xerographic office photocopying was introduced by Xerox in 1959, and it gradually replaced copies made by Verifax copier, Verifax, Photostat, carbon paper, mimeograph machines, and other duplicating machines. Photocopying is widely used in the business, education, and government sectors. While there have bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Beach, Washington
Long Beach is a city in Pacific County, Washington, United States. The population was 1,392 at the 2010 census. History Long Beach began when Henry Harrison Tinker bought a land claim from Charles E. Reed in 1880. He platted the town and called it "Tinkerville." Long Beach was officially incorporated on January 18, 1922. From 1889 to 1930, a narrow-gauge railroad called the Ilwaco Railway and Navigation Company ran up the whole peninsula. The Long Beach depot was built between First and Second Streets on the east side of the track, which ran north along "B" Street. A major destination in Long Beach was Tinker's Hotel, later renamed the Long Beach Hotel, and built very close to the station. This was the second hotel built at the site by Henry Harrison Tinker, the founder of Long Beach. Tinker's first hotel burned down in 1894. He built another one just a few feet to the east and south of the rail depot.Hobbs and Lucero, ''Long Beach Peninsula'', at 24 The image in the galle ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Antiproton
The antiproton, , (pronounced ''p-bar'') is the antiparticle of the proton. Antiprotons are stable, but they are typically short-lived, since any collision with a proton will cause both particles to be annihilated in a burst of energy. The existence of the antiproton with electric charge of , opposite to the electric charge of of the proton, was predicted by Paul Dirac in his 1933 Nobel Prize lecture. Dirac received the Nobel Prize for his 1928 publication of his Dirac equation that predicted the existence of positive and negative solutions to Einstein's energy equation (E = mc^2) and the existence of the positron, the antimatter analog of the electron, with opposite charge and spin. The antiproton was first experimentally confirmed in 1955 at the Bevatron particle accelerator by University of California, Berkeley physicists Emilio Segrè and Owen Chamberlain, for which they were awarded the 1959 Nobel Prize in Physics. In terms of valence quarks, an antiproton consists of two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Owen Chamberlain
Owen Chamberlain (July 10, 1920 – February 28, 2006) was an American physicist who shared with Emilio Segrè the Nobel Prize in Physics for the discovery of the antiproton, a sub-atomic antiparticle. Biography Born in San Francisco, California, Chamberlain graduated from Germantown Friends School in Philadelphia in 1937. He studied physics at Dartmouth College, where he was a member of Alpha Theta chapter of Theta Chi fraternity, and at the University of California, Berkeley. He remained in school until the start of World War II, and joined the Manhattan Project in 1942, where he worked with Segrè, both at Berkeley and in Los Alamos, New Mexico. He married Beatrice Babette Copper (d. 1988) in 1943, with whom he had four children. In 1946, after the war, Chamberlain continued with his doctoral studies at the University of Chicago under physicist Enrico Fermi. Fermi acted as an important guide and mentor for Chamberlain, encouraging him to leave behind theoretical physi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emilio Segrè
Emilio Gino Segrè (1 February 1905 – 22 April 1989) was an Italian-American physicist and Nobel laureate, who discovered the elements technetium and astatine, and the antiproton, a subatomic antiparticle, for which he was awarded the Nobel Prize in Physics in 1959 along with Owen Chamberlain. Born in Tivoli, near Rome, Segrè studied engineering at the University of Rome La Sapienza before taking up physics in 1927. Segrè was appointed assistant professor of physics at the University of Rome in 1932 and worked there until 1936, becoming one of the Via Panisperna boys. From 1936 to 1938 he was director of the Physics Laboratory at the University of Palermo. After a visit to Ernest O. Lawrence's Berkeley Radiation Laboratory, he was sent a molybdenum strip from the laboratory's cyclotron accelerator in 1937, which was emitting anomalous forms of radioactivity. After careful chemical and theoretical analysis, Segrè was able to prove that some of the radiation was being pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scientists From Oakland, California
A scientist is a person who conducts Scientific method, scientific research to advance knowledge in an Branches of science, area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century in science, 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have Terminal degree, advanced degrees in an area of science and pursue careers in various Sector (economic), sectors of the economy such ...
