Canals Interrupted (haikimagazine.com)
Never underestimate the importance of a big ditch, especially if it links two oceans. Canals allow for the rapid and free flow of goods, keeping the global economy ticking. Any threat to a major shipping canal means economic and political turmoil. Look at the Suez Crisis of 1956: when Egypt nationalized the Suez Canal, Israel, France, and Britain invaded, and the former Soviet Union threatened to bombard Europe with nuclear missiles if the invading forces did not withdraw.- Russell’s paradox (Wikipedia)
In mathematical logic, Russell’s paradox (also known as Russell’s antinomy) is a set-theoretic paradox published by the British philosopher and mathematician Bertrand Russell in 1901. Russell’s paradox shows that every set theory that contains an unrestricted comprehension principle leads to contradictions. The paradox had already been discovered independently in 1899 by the German mathematician Ernst Zermelo. However, Zermelo did not publish the idea, which remained known only to David Hilbert, Edmund Husserl, and other academics at the University of Göttingen. At the end of the 1890s, Georg Cantor – considered the founder of modern set theory – had already realized that his theory would lead to a contradiction, as he told Hilbert and Richard Dedekind by letter.
