You may know that Pi(e) day is celebrated on 3/14. It’s a day commemorating the mathematical beauty of Pi (3.1415 etc) with the culinary beauty of Pie.
But today I learned that Ancient Egyptians, whose mathematical skills did not progress beyond the average U.S. Algebra 2 (and were terrible with fractions), thought Pi was 3.16. It’s pretty close… but more importantly, it means you can totally celebrate two pi(e) days now.
