With the original printed wrappers bound in the October-November volume, in a very sturdy and quite fine library binding.
Provenance: National Bureau of Standards, with their identification gilt-stamped on the spine bottom, and a rubber stamp on the front wrappers. Very fine copies, brilliant but for this. $950
- The authors (Chamberlain and Segre) were awarded the Nobel Prize in Physics in 1959 for their production (using the new bevatron accelerator) and identification of the antiproton, which had been predicted earlier by PAM Dirac (in 1928) and discussed in his 1933 Nobel acceptance speech. "The antiproton was experimentally confirmed in 1955 by University of California, BerkeleyphysicistsEmilio Segrè and Owen Chamberlain, for which they were awarded the 1959 Nobel Prize in Physics. An antiproton consists of two up antiquarks and one down antiquark (uud). The properties of the antiproton that have been measured all match the corresponding properties of the proton, with the exception that the antiproton has opposite electric charge and magnetic moment than the proton. The question of how matter is different from antimatter remains an open problem, in order to explain how our universe survived the Big Bang and why so little antimatter exists today."--Wiki
In the spirit of great scientists writing for the Encyclopedia Britannica, Segre made the entry in 1960 for "proton" for the EB's 14th edition.
