A number of mathematical models were displayed at the 1893 World’s Columbian Exhibition to promote the idea that students must visualize algebraic relationships through geometry. Today, algebraic geometry serves as a source of deep insight throughout mathematics. #MathAtSFO

German mathematician Alexander Brill (1842–1935) created some of the earliest mathematical models which were made from plaster. These models allowed students to see the geometry of complex functions, revolutionary to mathematics at the time. #MathAtSFO #mathematicalmodels

Today, STEM (science, technology, engineering, math) teaching integrates four disciplines into a program offering practical instruction with “real-world” applications. Even so, universal mathematics literacy remains an ongoing challenge. #MathAtSFO

Advocates of the “New Math” movement encouraged learning through discovery rather than just memorizing methods of solving problems with the goal of creating a new generation of scientists and mathematicians. #MathAtSFO

During the early twentieth century, the idea that children should spend time at play or in school, led to toys that encouraged learning. At mid-century, a large school-aged population triggered an urgency for new, more rigorous mathematical curricula in the US. #MathAtSFO

Gears within the M-209 have prime-number ratios to prevent repetitive positions—with over one million positions before the key repeats. The M-209, however, is not fully secure, partly because its prime numbers are short. #MathAtSFO #Mathematics #Math #cryptology #cipher

During World War II, all sides used mechanical ciphers. The U.S. military’s M-209 portable crypto machine required users to encrypt text one letter at a time. By turning a crank, the scrambled message printed out on paper tape. #MathAtSFO #Math #cryptology #cipher

An outsider cannot unscramble the code without knowing the secret letter. But if many messages are sent, an enemy can statistically detect the pattern of the device and the secret key.
