Pi Day, celebrated annually on March 14th (3/14), has evolved from a niche holiday for mathematicians into a massive internet phenomenon. While the day honors the mathematical constant π, the internet quickly turned it into a pun-filled celebration involving both complex geometry and actual baked pie. These memes typically range from high-brow calculus jokes to simple wordplay about 'eating Pi,' often featuring famous figures like Albert Einstein—whose birthday conveniently falls on the same date. The meme culture surrounding Pi Day serves as a perfect bridge between educational content and relatable humor, making it a viral staple for schools, scientists, and pastry enthusiasts every spring.
