US Congress officially recognized the Pi Day celebration in 2009. This celebration has inspired unusual activities such as eating circular cakes or pies, making pizzas with the shape of the symbol, or dressing up as Albert Einstein, who also has his birthday during Pi Day.

NASA features this math challenge yearly. San Francisco’s Exploratorium hosts Pi-related activities every year. And today is when The Massachusetts Institute of Technology reveals its undergraduate admissions decisions, doing this since 2012. A tweet featuring the four math challenges is below.
