Modern cryptosystems rely on huge prime numbers for secure cyphers. Historically, secret messages could be sent by replacing one letter with another. #MathAtSFO #Mathematics #Math #cryptologists #ciphers This tweet was posted on March 28, 2022.

Check out our exhibition “Mathematics: Vintage and Modern” for the math behind Rubik’s cubes, Klein bottles, and knots, among much, much more. It’s on view post-security in Terminal 2 and online at https://t.co/loGSK6ryKu #PiDay #MathAtSFO #math This tweet was posted on March 14, 2022.

It does everything that a pocket calculator can do except that it is entirely mechanical—no battery, no keypad, no liquid-crystal display. To add numbers, users simply turn a crank. #MathAtSFO This tweet was posted on February 16, 2022.

From 1947 to 1972, the Curta calculator sold for around $125.00 and graced the pockets of engineers, accountants, surveyors, and pilots. Collectors cherish its meticulous engineering, likening the Curta to a fine pocket watch. #MathAtSFO This tweet was posted on February 16, 2022.

During the 1930s, the smallest calculator weighed several pounds. Austrian engineer Curt Herzstark (1902–1988) conceived of a pocket-sized calculator that could add, subtract, multiply, and divide. #MathAtSFO This tweet was posted on February 16, 2022.

Sugihara’s anomalous mirror symmetry takes advantage of our expectation that lines appearing to be straight must be physically straight. Viewed in mirrors, his illusions show a change in appearance when seen in different directions. #MathAtSFO #KokichiSugihara This tweet was posted on December 29, 2021.

Viewed in mirrors, Sugihara’s illusions show a change in appearance when seen in different directions. He uses projective geometry to create anomalous mirror symmetry. The upper surface of these objects appears flat, but they are actually curved along the sight lines. #MathAtSFO This tweet was posted on December 29, 2021.

Do you see the tricks these objects are playing? Renowned mathematician Kokichi Sugihara of Meiji University in Tokyo creates ambiguous sculptures—solid objects which seem to defy common-sense notions of direction and shape. #MathAtSFO #KokichiSugihara This tweet was posted on December 29, 2021.

"It’s no secret that SFO has some of the best darn exhibitions in the Bay Area." #MathAtSFO keeps excellent company on @KQEDarts list of 2021's best art and exhibitions. Thanks for the mention! https://t.co/1Qb5LIBsDF This tweet was posted on December 10, 2021.
