Under enemy fire on March 25, 1945, radio operator Temple Leslie Bourland bailed out of a C-47 over the Rhine. He injured his hip but avoided capture, hiding in a foxhole for two days while using his parachute as a blanket. When Allied troops discovered him he returned to his unit.
That summer he met San Antonio secretary Rosalie Hierholzer, and during their brief courtship he showed her the bullet-riddled parachute, which he kept in his trunk. Rosalie’s aunt Lora offered to make it into a bridal gown, and Rosalie wore it at their wedding. The train still retained some of the military seams.
Cried the maid: “You must marry me, Hume!”
A statement that made David fume.
He said: “In cause and effect,
There is a defect;
That it’s mine you can only assume.”

Thomas Hobbes of Malmesbury thought
Life was nasty and brutish and short;
But contracts, once made,
Would come to our aid,
And ensure modest comfort — at court.

There was a young man who said: “Ayer
Has answered the atheist’s prayer,
For a Hell one can’t verify
Surely can’t terrify —
At least till you know you are there.”
The roots of the word helicopter are not heli and copter but helico and pter, from the Greek “helix” (spiral) and “pteron” (wing).
G.L.M. de Ponton’s 1861 British patent says, “The required ascensional motion is given to my aerostatical apparatus (which I intend denominating aeronef or helicoptere,) by means of two or more superposed horizontal helixes combined together.”
In 1873 a Methodist missionary in New York City heard rumors of a little girl who was kept locked in a tenement and regularly whipped. She uncovered a shocking case of neglect and abuse that made headlines around the world. In this week’s episode of the Futility Closet podcast we’ll tell how one girl’s ordeal led to a new era in child welfare.
We’ll also outsource Harry Potter and puzzle over Wayne Gretzky’s accomplishments.
I have picked one color (black or white) and one shape (square or circle). A symbol that possesses exactly one of the properties I have picked is called a THOG. The black circle is a THOG. For each of the other symbols, is it (a) definitely a THOG, (b) undecidable, or (c) definitely not a THOG?
Cognitive psychologist Peter Wason invented this puzzle in 1979 to demonstrate some weaknesses in human thinking. In pilot studies, 0 of 10 student barristers were able to solve it correctly, with one arguing for more than an hour against the correctness of Wason’s solution. Seven of 14 medical students solved it, taking an average of 6.3 minutes. (“This is quite an impressive result.”) One young doctor solved it in his head in about a minute and said, “I would not let any doctor near me who couldn’t solve that problem.” What’s the answer?
In saying “I have picked one color and one shape,” in effect I am saying, “I have picked one of the symbols.” I can’t have chosen the black circle, because we know that symbol has only one of the required attributes. The symbol I’ve chosen must be either the black square or the white circle. Either way, the white square would match my choice in exactly one particular, so it’s definitely a THOG. If I’ve chosen the black square then the black square has both chosen attributes and the white circle has neither; equally, if I’ve chosen the white circle then the white circle has both chosen attributes and the black square has neither. Either way, neither of these symbols is a THOG. So the white square is definitely a THOG and the other two symbols definitely aren’t.
“In one sense the THOG problem is utterly trivial,” writes Wason. “And yet it is non-trivial in the sense that it is astonishingly easy for some individuals and astonishingly difficult for others. At the very least it does seem a cogent test of formal operational thought in an abstract sphere.” See the link below for more details.
The media pavilion for the 2002 Swiss National Expo was a cloud. Organizers built a curved building fitted with more than 30,000 nozzles that pumped water from Lake Neuchâtel into a fine mist, creating a floating 90-meter fog bank whose contours were controlled by a computerized weather system.
Artist Antony Gormley took this idea a step further in 2007 with Blind Light, a 10-meter-square glass vitrine filled with mist and lit by 7,000 lux of intense fluorescent light that reduced visibility to less than an arm’s length.
“One could, and did, get temporarily lost in its 90 percent humidity,” writes Richard Hamblyn in Clouds: Nature and Culture (2017). “The intended effect of Gormley’s ‘bright, cuboid cloud’ was to overwhelm the senses, as though one had walked into a cloud, literally and figuratively, entering a cold, damp, unsettling world of enveloping isolation.”
The 1967 version of Casino Royale, starring David Niven, set an unlikely milestone: Its soundtrack album became famous among audio purists for the quality of its sound.
“The legend is that the original master tape had ‘mad’ levels on it,” audiophile Harry Pearson told the New York Times in 1991. “Once the meters pass zero, it means that you’re saturating the tape and running the risk of distortion. On ‘Casino,’ they used a supposedly very fancy grade of tape, and the engineers really pushed it, so the meters were typically running deep into the red — plus one, plus two, plus three, plus four.” The result is an extremely wide dynamic range.
A particular high point is Dusty Springfield’s “The Look of Love” (Track 2). Springfield recorded her vocal in a “tiny isolation booth, so on a really good system, you can hear her voice emerging from what sounds like a little hole in space. She’s not part of the general orchestral acoustic, and once your system gets to a certain point, you can hear that.”
Pearson said the soundtrack came to serve as a benchmark at Absolute Sound, the audiophile bible he founded in 1973. “Whenever we get a piece of equipment that we think is setting new records, out comes ‘Casino,'” he said. “The better your system gets, the more you get out of that album.”
Draw a line from each vertex to the interior point where the four regions meet. This divides each region into two triangles. On each side of the large figure (north, south, east, and west), two of these triangles are neighbors and have the same area (because they have the same base and height) (here’s a figure).
The four triangles that make up the northeast and southwest regions have the same area as the four triangles that make up the northwest and southeast regions. This means that each pair of diagonally opposite regions makes up half the total area of the figure. So the missing area is 28 cm2.

“The hardest of all adventures to speak of is music, because music has no meaning to speak of. If music could be translated into human speech it would no longer need to exist. Like love, music’s a mystery which, when solved, evaporates.” — Ned Rorem, Music From Inside Out, 1967
“Music has no subject beyond the combinations of notes we hear, for music speaks not only by means of sounds, it speaks nothing but sound.” — Eduard Hanslick
“Music expresses that which cannot be said and on which it is impossible to be silent.” — Victor Hugo
But music moves us, and we know not why;
We feel the tears, but cannot trace their source.
Is it the language of some other state,
Born of its memory? For what can wake
The soul’s strong instinct of another world,
Like music?
— Letitia Elizabeth Landon, The Golden Violet, 1827
