“Learning never exhausts the mind”*…
As regular readers know, each year Tom Whitwell shares a list of the more intriguing things he’s learned over the year; happily, 2021 is no exception…
10% of US electricity is generated from old Russian nuclear warheads. [Geoff Brumfiel]
The entire global cosmetic Botox industry is supported by an annual production of just a few milligrams of botulism toxin. Pure toxin would cost ~$100 trillion per kilogram. [Anthony Warner]
Wearing noise cancelling headphones in an open-plan office helps a little bit — reducing cognitive errors by 14% — but actual silence reduces those errors by one third. [Benjamin Müller & co]
Until 1873, Japanese hours varied by season. There were six hours between sunrise and sunset, so a daylight hour in summer was 1/3rd longer than an hour in winter. [Sara J. Schechner]

As we live and learn, we might recall that it was on this date in 1545, in response to the Protestant Reformation, that the Council of Trent (Concilium Tridentinum) was convened by the Roman Catholic Church. Its work concluded in 1563; and its results were published in 1564, condemning what the Catholic Church deemed to be the heresies of Protestants. The embodiment of the Counter-Reformation, The Council of Trent established a firm and permanent distinction between the two practices of faith.

As we have fun with facts, we might send fascinatingly-illustrated birthday greetings to David Brewster; he was born on this date in 1781. A physicist, inventor, author, and academic administrator, he is best remembered for his work in optic (especially the phenomenon of polarization). Brewster was a pioneer in photography; he invented an improved stereoscope, which he called “lenticular stereoscope” and which became the first portable 3D-viewing device. He also invented the binocular camera, two types of polarimeters, the polyzonal lens, the lighthouse illuminator, and (perhaps most relevantly to today’s post) the kaleidoscope. For this work, William Whewell dubbed him the “father of modern experimental optics” and “the Johannes Kepler of optics.”
