Your nose can tell a molecule from its mirror image, and life builds its proteins and genes from one form alone. No one knows why. This year’s chemistry prize went in part for a sealed flask that does much the same, and the Academy wrote: “Other than life itself, no one had previously achieved this feat.”
Why we’re pointing you there
On October 7 the Royal Swedish Academy of Sciences gave the chemistry prize to Henri Kagan, 95, and Kenso Soai, 76, for work on how a slight preference for one mirror image can grow. Intellicurean takes the Academy’s most generous sentence at its word and follows the flask back to where the story starts: wine diamonds under a cork, stray crystals in the vats of an acid works in Alsace, and Louis Pasteur in 1848 sorting crystals into left and right by eye, then repeating it for the old physicist Jean-Baptiste Biot in Biot’s own rooms. From there it moves through Kagan’s “marriage,” in which a deliberately flawed catalyst does better than anyone expected because mismatched pairs sit out; a flask that existed only on paper in 1953; Soai’s thirty-seven sealed flasks, started with nothing one-handed, that came out eighteen one way and nineteen the other; and a stone that fell near Murchison, in Victoria, in 1969, carrying amino acids that lean.
What we liked most is how the essay resists both temptations of its subject. It never lets the flask stand in for how life did it, which the committee itself is careful to say it isn’t, and it never lets the mystery go soft: it says plainly that an amplifier “makes a cause indistinguishable from an accident.” It is also a story full of people, from Biot taking the young Pasteur by the arm to a laureate who heard the news while out shopping and spoke first of Pasteur. Where the essay turns the Academy’s compliment around, and what it makes of the stone, we’ll leave to the essay.
