"There is a beauty in discovery. There is mathematics in music, a kinship of science and poetry in the description of nature, and exquisite form in a molecule. Attempts to place different disciplines in different camps are revealed as artificial in the face of the unity of knowledge. All literate men are sustained by the philosopher, the historian, the political analyst, the economist, the scientist, the poet, the artisan and the musician."
—Glenn Seaborg

• ... that acclaimed chemist Glenn T. Seaborg developed the extraction process used by the Manhattan Project to isolate the plutonium fuel for the second atomic bomb; that Seaborg e advised ten US Presidents — from Harry S. Truman to Bill Clinton — on nuclear policy, and was Chairman of the United States Atomic Energy Commission from 1961 to 1971, where he pushed for commercial nuclear energy and the peaceful applications of nuclear science; and that throughout his career, Seaborg worked for arms control, being a signatory to the Franck Report and contributing to the Limited Test Ban Treaty, the Nuclear Non-Proliferation Treaty, and the Comprehensive Test Ban Treaty?

• ... that mathematician, monk, and academic Michael Stifel published his Ein Rechenbuchlin vom EndChrist. Apocalyps in Apocalypsim ("A Book of Arithmetic about the AntiChrist.

• ... that mathematician and academic Giuseppe Peano was a founder of mathematical logic, to which Peano made key contributions to the rigorous and systematic treatment of the method of mathematical induction, and set theory, to which he contributed much notation, and that the standard axiomatization of the natural numbers is named the Peano axioms in his honor?
