Thirteen Fun Things For and About PiDay, which was yesterday, by the way! I'm not really that into math, but the heroine in my upcoming release, the second book in my Badge Bunnies Series is, (her favorite number is three - not surprising since she has sex with two very hot cops!) so she talked me into unleashing my inner geek!
1. Pi day is an actual holiday to celebrate the mathematical number of pi or 3.14
for short. March 14 (3:14) is usually the time of the celebration with food and
activities for those to enjoy.
2. Mathematician to Baker: "Pi r squared"
Baker: "No! Pies are round!"
3. Q: What do you get when you cut a jack o'lantern by its diameter?
A: Pumpkin Pi.
4. The origin of Pi Day is unknown and it is likely that it was first observed by many people. Possibly the earliest official or large-scale celebration of Pi Day was organized by Larry Shaw in 1988 at the San Francisco Exploratorium , where Shaw worked as a pyhsicist, with staff and public marching around one of its circular spaces, then consuming fruit pies.
5. Question: What do you get if you divide the circumference of a bowl of ice cream by its diameter?
Answer: Pi a’la mode.
6. On March 12, 2009, the U.S. House of Representatives passed a resolution recognizing March 14, 2009, as National Pi Day.
7. Albert Einstein's birthday is PiDay.
8. A mathematician, a physicist, and an engineer are all given identical rubber balls and told to find the volume. They are given anything they want to measure it, and have all the time they need.
The mathematician pulls out a measuring tape and records the circumference. He then divides by two times pi to get the radius, cubes that, multiplies by pi again, and then multiplies by four-thirds and thereby calculates the volume.
The physicist gets a bucket of water, places 1.00000 gallons of water in the bucket, drops in the ball, and measures the displacement to six significant figures.
And the engineer? He writes down the serial number of the ball, and looks it up.
9. Pi is a Greek letter pronounced like the English letter “p”, and means perimeter.
10. Princeton has an annual party celebrating Pi Day and Einstein’s birthday.
11. Pi represents the relationship between a circle’s diameter (its width) and its circumference (the distance around the circle).
12. You can use Pi to find the area of a circle with the equation
Area = 2Pi x radius squared
13. You can also use it to find the volume of a cylinder with the equation
Volume = (pi x radius squared) x the height of the cylinder
