Period, Full Start…

Along these same lines, readers might also be interested in the “Perpetual Notion Machine” (which includes, as a bonus, the story of Dmitri Mendeleev and the “real” Periodic Table…)  See also the Periodic Table of Typefaces (“‘There are now about as many different varieties of letters as there are different kinds of fools…’“) and the Periodic Table of Visualization Methods (“Now See Here…“).

As we constructively stack our writers’ blocks, we might wish a thoughtful Happy Birthday to Immanuel Kant; he was born on this date in 1724 in Königsberg, Prussia (which is now Kaliningrad, Russia).  Kant is of course celebrated as a philosopher, the author of Critique of Pure Reason (1781), Critique of Practical Reason (1788), and Critique of Judgment (1790), and father of German Idealism (et al.).

But less well remembered are the contributions he made to science, perhaps especially to astronomy, before turning fully to philosophy.  For example, his General History of Nature and Theory of the Heavens (1755) contained three anticipations important to the field: 1) Kant made the nebula hypothesis ahead of Laplace. 2) He described the Milky Way as a lens-shaped collection of stars that represented only one of many “island universes,” later shown by Herschel. 3) He suggested that friction from tides slowed the rotation of the earth, which was confirmed a century later.  Similarly, Kant’s writings on mathematics were cited as an important influence by Einstein.

The principle of explosion (ex falso sequitur quodlibet*), a law of classical logic, asserts that “anything follows from a contradiction”– that’s to say, once a contradiction has been asserted, any proposition (or of course, its opposite) can be inferred from it. Symbolically, that’s:

Readers may be relieved to know that two different models of paraconsistent logic allow for contradiction without explosion.

* “from falsehood/contradiction follows what pleases”

As we revisit our debate strategies, we might recall that it was on this date in 1869 that Dmitri Mendeleev presented the first periodic table of elements to the Russian Chemical Society.  Mendeleev’s chart captured the known elements of the day, and allowed him to predict the properties of elements yet to be discovered.
