In 1930 French architect Emilio Terry offered a model of a spiral house that he called en colimaçon (“snail-style”), illustrating his view that architecture expressed a “dream to be realized.”
It looks odd, but the interior is relatively conventional. “Although the snail shape has been imposed on the exterior,” writes Ulrich Conrads in The Architecture of Fantasy, “no advantage is derived from it, either regarding the total volume or the interrelationship of the spatial sections.”
World War I’s final ceasefire went into effect at a precise moment: 11:00 a.m. Paris time on Nov. 11, 1918. The French had worked out a way of recording sound signals on film — they used it to infer the position of enemy guns by determining the time between the sound of a shell’s firing and its explosion. This gives us a visual record of the end of the fighting, six representative seconds from the periods before and after the armistice. (Note, though, that the minute immediately before and the one immediately after the ceasefire aren’t shown, “to emphasize the contrast.”)
I don’t have an original source for this — Time magazine credits the U.S. Army Signal Corps.
The first point to which attention should be called is that the comic does not exist outside the pale of what is strictly human. A landscape may be beautiful, charming and sublime, or insignificant and ugly; it will never be laughable. You may laugh at an animal, but only because you have detected in it some human attitude or expression. You may laugh at a hat, but what you are making fun of, in this case, is not the piece of felt or straw, but the shape that men have given it,– the human caprice whose mould it has assumed. It is strange that so important a fact, and such a simple one too, has not attracted to a greater degree the attention of philosophers. Several have defined man as ‘an animal which laughs.’ They might equally well have defined him as an animal which is laughed at; for if any other animal, or some lifeless object, produces the same effect, it is always because of some resemblance to man, of the stamp he gives it or the use he puts it to.
— Henri Bergson, Laughter, 1911
In 1920, after Lenin delivered a speech in Petrograd to troops departing to fight in the Soviet-Polish war, Russian artist El Lissitzky challenged his architecture students to design a speaker’s platform on a public square. The result was the Lenin Tribune, a rostrum that can bear its speaker aloft to address a crowd of any size. In a letter to the art historian and critic Adolf Behne, Lissitzky wrote:
I have now received some sketches of former works and have reconstructed the design. Therefore I do not sign it as my personal work, but as a workshop production. The diagonally-standing structure of iron latticework supports the movable and collapsible balconies: the upper one for the speaker, the lower one for guests. An elevator takes care of transportation. On top there is a panel intended for slogans during the day and as a projection screen at night. The gesture of the entire speaker’s platform is supposed to enhance the motions of the speaker. (The figure is Lenin.)
Here the message reads PROLETARIAT. Lissitzky later said he regretted not publishing the design when Vladimir Tatlin’s Monument to the Third International was attracting attention, so that the two might have competed against one another.
The University of Oxford has a bell that’s been ringing almost continuously since 1840. A little 4-millimeter clapper oscillates between two bells, each of which is positioned beneath a dry pile, an early battery. Due to the electrostatic force, the clapper is first attracted to and then repelled by each bell in turn, so it’s been ringing them alternately for 179 years. The operation conveys only a tiny amount of charge between the bells, which explains why it’s managed to run so long. The whole apparatus is kept under two layers of glass, but the ringing is so faint that it would be inaudible in any case.
It’s estimated that the bell has produced 10 billion rings so far — it holds the Guinness World Record as “the world’s most durable battery [delivering] ceaseless tintinnabulation.”
The briefest interview I’ve ever conducted was with Renato Dulbecco, who has since shared in a Nobel Prize for work in animal-cell culture and tumor viruses. Through his secretary, we had made an appointment. When I reached his office, he ushered me in, closed the door, sat down at his desk — and said that he was not going to talk to me. Startled, but respecting him at least for not having imposed on his secretary the task of rejection, I said something about the importance of getting scientific work across to the general public. Dulbecco replied, ‘We don’t do science for the general public. We do it for each other. Good day.’

(“I thanked him for the interview and left, promising myself to use it someday. He was correct, of course, though unusually candid.”)
A remarkable thematic chess puzzle by Bodo Van Dehn, 1951. White to move and win.
The solution is 10 moves long, but all Black’s moves are forced. (That’s a very valuable hint.)
Letter from Albert Einstein to J.E. Switzer, April 23, 1953:
Dear Sir
Development of Western Science is based on two great achievements; the invention of the formal logical system (in Euclidean geometry) by the Greek philosophers, and the discovery of the possibility to find out causal relationship by systematic experiment (Renaissance). In my opinion one has not to be astonished that the Chinese sages have not made these steps. The astonishing thing is that these discoveries were made at all.
Sincerely yours,
A. Einstein
The “Lo Shu square” is the 3 × 3 square enclosed in dashed lines at the center of the diagram above. It’s “magic”: Each row, column, and long diagonal (marked in red) sums to 15. William Walkington has discovered a new magic property — imagine rolling the square into a tube (in either direction), and then bending the tube into a torus. And now imagine hopping from cell to cell around the torus with a “knight’s move” — two cells over and one up. (The extended diagram above helps with visualizing this — follow the blue lines.) It turns out that each such path touches three cells, and these cells always sum to 15. So the square is even more magic than we thought.
More info here. (Thanks, William.)
