The traumata of warfare were certainly nothing new when World War 1 broke out. But the extreme and prolonged exposure to machine gun fire, artillery bombardments and trench warfare led to a new kind of psychological disorder: Shell Shock. Soldiers who were perfectly fine on the outside, were incapable of fighting or living a normal life anymore.

Richard Feynman’s shortcut for detecting pseudo-scientific bullshit
At Open Culture, Josh Jones discusses Richard Feynman’s suggestion for non-scientists to evaluate whether a claim is scientific or pseudo-scientific nonsense:
The problem of demarcation, or what is and what is not science, has occupied philosophers for some time, and the most famous answer comes from philosopher of science Karl Popper, who proposed his theory of “falsifiability” in 1963. According to Popper, an idea is scientific if it can conceivably be proven wrong. Although Popper’s strict definition of science has had its uses over the years, it has also come in for its share of criticism, since so much accepted science was falsified in its day (Newton’s gravitational theory, Bohr’s theory of the atom), and so much current theoretical science cannot be falsified (string theory, for example). Whatever the case, the problem for lay people remains. If a scientific theory is beyond our comprehension, it’s unlikely we’ll be able to see how it might be disproven.
Physicist and science communicator Richard Feynman came up with another criterion, one that applies directly to the non-scientist likely to be bamboozled by fancy terminology that sounds scientific. Simon Oxenham at Big Think points to the example of Deepak Chopra, who is “infamous for making profound sounding yet entirely meaningless statements by abusing scientific language.” (What Daniel Dennet calls “deepities.”) As a balm against such statements, Oxenham refers us to a speech Feynman gave in 1966 to a meeting of the National Science Teachers Association. Rather than asking lay people to confront scientific-sounding claims on their own terms, Feynman would have us translate them into ordinary language, thereby assuring that what the claim asserts is a logical concept, rather than just a collection of jargon.
The example Feynman gives comes from the most rudimentary source, a “first grade science textbook” which “begins in an unfortunate manner to teach science”: it shows its student a picture of a “windable toy dog,” then a picture of a real dog, then a motorbike. In each case the student is asked “What makes it move?” The answer, Feynman tells us “was in the teacher’s edition of the book… ‘energy makes it move.’” Few students would have intuited such an abstract concept, unless they had previously learned the word, which is all the lesson teaches them. The answer, Feynman points out, might as well have been “’God makes it move,’ or ‘Spirit makes it move,’ or, ‘Movability makes it move.’”
Instead, a good science lesson “should think about what an ordinary human being would answer.” Engaging with the concept of energy in ordinary language enables the student to explain it, and this, Feynman says, constitutes a test for “whether you have taught an idea or you have only taught a definition.
The Greatest Raid of All

THE GREATEST RAID OF ALL “What a story it is, straight out of a Commando comic book.” (The Guardian) Jeremy Clarkson tells the story of one of the most daring operations of World War II — the Commando raid on the German occupied dry dock at St. Nazaire in France on 28th March 1942. It was an operation so successful and so heroic that it resulted in the award of five Victoria Crosses and 80 other decorations for gallantry.
QotD: An appropriate epitaph
When the epitaph for America’s political class is written, it may read something like this:
“Real unemployment was above 10%, barbarians were reintroducing slavery and public beheadings in the Middle East, the national infrastructure was crumbling, the Presidential elections were convulsed by large-scale populist revolts in both parties, and what was the elite cause du jour? Unisex restrooms.”
