Hello everyone! Did you know that
tomorrow today is 3/14?
And do you know what 3/14 looks like?
And what is
The first 3 digits of 𝜋!
This countdown will count all the days, hours, minutes, and seconds until 𝜋 day! Get ready to memorize 100 digits of pi!
I can memorize 28 digits of pi!
Can you do better? No looking at any works of reference or any websites that relate to 𝜋 in any way.
Create a project in any language related to 𝜋! Post them here and I will put them in a new gallery!
Please vote up!
If we can get to 3 votes, it would be close enough to 𝜋 :/ Reached! If we can get to 31 votes, it would be even closer to 𝜋⨯10 :) Reached!
If we can get to 314 votes, it would be even closer to 𝜋⨯100 :D
Even if you can't remember that many digits, at least know
before 𝜋 day!
What is 𝜋?
𝜋 is an irrational number meaning it never terminates (stops), and it has no human-distinguishable pattern to it. (meaning the numbers are near random to the human).
𝜋 seems pretty useless...
𝜋 is anything but useless! You can use it to calculate the area of a circle: 𝜋r², and the surface area of a sphere: 4𝜋r² and basically calculate the areas, surface areas, and volumes of anything round.
How do you derive 𝜋?
Cut out a circle, and measure along the sides (circumference).
Then, measure the diameter. To find it, move your ruler along the circle and measure the lengths. The longest length is the diameter.
Now, your approximation of 𝜋 is
circumference ÷ diameter.
