Walther Bothe - Internal Reports

Internal Reports

The following reports were published in Kernphysikalische Forschungsberichte (Research Reports in Nuclear Physics), an internal publication of the German Uranverein. The reports were classified Top Secret, they had very limited distribution, and the authors were not allowed to keep copies. The reports were confiscated under the Allied Operation Alsos and sent to the United States Atomic Energy Commission for evaluation. In 1971, the reports were declassified and returned to Germany. The reports are available at the Karlsruhe Nuclear Research Center and the American Institute of Physics.

Famous quotes containing the words internal and/or reports:

    “A State, in idea, is the opposite of a Church. A State regards classes, and not individuals; and it estimates classes, not by internal merit, but external accidents, as property, birth, etc. But a church does the reverse of this, and disregards all external accidents, and looks at men as individual persons, allowing no gradations of ranks, but such as greater or less wisdom, learning, and holiness ought to confer. A Church is, therefore, in idea, the only pure democracy.”
    —Samuel Taylor Coleridge (1772–1834)

    “I think a Person who is thus terrifyed [sic] with the Imagination of Ghosts and Spectres much more reasonable, than one who contrary to the Reports of all Historians sacred and profane, ancient and modern, and to the Traditions of all Nations, thinks the Appearance of Spirits fabulous and groundless.”
    —Joseph Addison (1672–1719)
