In case you missed it, last Saturday was Pi Day

If you spent last Saturday blissfully unaware that the calendar had aligned into the world’s favorite infinite snack, don’t feel too bad—most of us were far too busy living in the “real world” to notice we were surrounded by irrational constants. March 14th came and went with its usual mathematical flair, giving engineers and pun-enthusiasts everywhere a hall pass to eat dessert for breakfast in the name of “science.” Whether you celebrated by calculating the circumference of your coffee mug or simply by inhaling a slice of apple crumble, it’s time to round up the highlights of the day that proves, once and for all, that 3.14 is the only number tasty enough to deserve its own holiday.

The History of Pi

Pi was not “founded” by a single person in the way a company or a town is. Instead, it was discovered and refined by various civilizations over thousands of years.

Ancient Babylonians and Egyptians had rough estimates of pi as early as 1900 BC. However, the first rigorous calculation of π is often attributed to Archimedes of Syracuse (287–212 BC). He used polygons to trap the circle, proving that π lies between 31/7 and 310/71.

The use of the Greek letter π as we know it today was popularized by Leonhard Euler in 1737, though it was first introduced by William Jones in 1706.

Why Does Pi Matter?

Pi is more than just a number; it is an “irrational” number, meaning it never ends and never develops a repeating pattern. This infinite nature makes it a cornerstone of geometry, trigonometry, and physics.

Without pi, we wouldn’t be able to accurately calculate everything from the trajectory of satellites to the way sound waves travel. It appears in the spiral of DNA, the ripples in a pond, and even the way the stars move in the night sky.

Pi Day: A Modern Tradition

Pi Day was founded in 1988 by physicist Larry Shaw at the San Francisco Exploratorium. He chose March 14th because the date (3/14) represents the first three digits of pi (3.14). In 2009, the U.S. House of Representatives officially recognized March 14th as National Pi Day.

Fun Facts for the Peninsula

• A Natural Match: Pi is used by structural engineers and local builders to calculate curves and circular volumes. If you’ve ever admired a perfectly round gazebo or a curved driveway, you have pi to thank.
• The Ultimate Memory Challenge: Many people compete to see how many digits they can memorize. The current world record involves reciting over 70,000 digits!
• Albert Einstein’s Birthday: In a twist of fate, March 14th is also the birthday of the most famous physicist in history, Albert Einstein.
• The “Pi” Song: If you want a fun way to get these numbers stuck in your head, check out “The Pi Song 4.0” by AsapSCIENCE. It’s a catchy tune that walks you through 400 digits of pi, starting with the classic 3.14159. It even gets a bit absurd, mentioning things like “blue flying bats” and “gold cats” to help the rhythm.

So, next March 14th, take a moment to appreciate the infinite complexity and simple beauty of a circle. Grab a slice of pie and celebrate the number that helps hold the world together.
