prior probability

That is the title of this autobiographical 2017 lecture by Ketanji Brown Jackson.

Sounds and words; papyrus and scrolls; books and pamphlets; photographs and movies; vinyl records and mp3 files — what will the next major media revolution look like? On this day (March 22) in 1896, the Lumière brothers, Auguste and Louis, screen a movie for the first time at a meeting of the Société pour l’Encouragement à l’Industrie. (Below is an enhanced version of one of their first films.)

The Old Hem, a beloved pub in Kharkiv dedicated to the memory of Ernest Hemingway, was destroyed by Russian shelling last week, and two civilians were killed in the attack. Via George Wright of the BBC, the full story is here.

This remarkable work of glass art by Trish Duggan (part of which is pictured below) is on display at the Imagine Museum in St Petersburg, Florida.

Either way, you may order this beautiful piece of floral wall art here (h/t: @pickover).

On this day (March 19) in 1931, the Governor of Nevada (Fred Balzar) signed two historic bills into law. One was a new “quickie divorce” law (see here, for example), making the Silver State the easiest place to get a divorce in the nation. The other was “The Wide Open Gambling Bill of 1931” (see here and here), which legalized games of chance across the State. (At the time, Nevada was the nation’s least populous state. See also this history of gaming in the Silver State.) My counter-factual question, however, is this: If Nevada had not enacted these modern-day laws in 1931, surely another State would have eventually done so, but which one? California? Florida? New York?

The map below purports to show the number of troops under direct NATO command in Central Europe — “only” 40,000! — and how these forces are distributed among the eight Central European member-nations of the NATO alliance (hat tip: u/kg177). My question, however, is this: is 40,000 men for such a vast region too little or too much?

You may have heard of “Murphy’s Law” before (see item #1 below), but did you know that there are at least four five different formulations of this famous law? Via Roger’s Bacon, here are the first four:

1. Murphy’s Law – “Anything that can go wrong will go wrong.”

2. Murphy’s Second Law – “Nothing is as easy as it looks.”

3. Murphy’s Third Law (also known as Hofstadter’s law) – “Everything takes longer than you think it will (even when you account for Murphy’s Third Law).”

4. Murphy’s Fourth Law – “If there is a possibility of several things going wrong, the one that will cause the most damage will be the one to go wrong.” (Corollary: if there is a worse time for something to go wrong, it will happen then.)

Bonus: Murphy’s Fifth Law (hat tip: Sheree) — “It will cost twice as much as anticipated.”
