Today is March 14th!
So? What’s so special about March 14th?
To many, March 14th is just another day of the year. To those math geeks out there, you would recognize today as Pi Day! Fortunately, Google is no different without a lack of number geeks. Today, Google continues its tradition of changing the logo (known as the Google Doodle) to reflect holidays.
π (Pi) is a mathematical constant that is used to calculate the circumference of a circle based on its diameter. Pi is an irrational number (goes on forever) but is typically rounded off as 3.14 or 22/7. So why do math geeks celebrate Pi Day? March 14th can be written as 3/14, which represents 3.14.
Google is celebrating Pi Day with their new doodle featuring an intricate design of formulas and circles.
On the right over the G, there is a circle showing the radius and the formula to find the circle’s area using the A=πr2 formula.
Over the two o’s which becomes 2 circles, we have two connecting semi-circles and to find the total distance, the formula would be 2π with the radius as 1, which is given under it.
The top part of the g shows Archimedes’ calculation of Pi (223/71 < π < 22/7). The bottom part shows the formula for finding the volume of a sphere (V = 4⁄3 πr3).
The l represents a cylinder and the formula for finding the volume of a cylinder is provided (V = πr2h).
And lastly, we have the e representing a circle and provides the formula for finding the circumference of a circle (C = 2πr).
How are you celebrating Pi Day? Are you having pie? :D Or creating an intricate design using pi-related figures like Google did? Leave your thoughts in the comments.
