Books

"Book Review: Autobiography of Mark Twain Volume 1." The book turns out to be a wonderful fraud on the order of the Duke and the Dauphin in their Shakespearean romp, and . . . still able to catch the public’s attention a century after he expired. New York Times (Decemer 16, 2010).

Fundamental Physics

"Size of a proton? Really small." But physicists can't agree on one number. Science News (December 17, 2010).

Internet

Tried to use "Google labs: Books Ngram Viewer" for the words related to my past activities:
Dosimetry vs irradiation —I made researches related to these words just in the years when these showed peaks.
Betatron vs linac —I worked with an electron linac around the years of the first peak of the linac.
Electron backscatter vs ion reflection —I studied the former in the years around its first peak; the latter, just during the years of its peak.
Quite interesting!
