Can you calculate Pi (π) by throwing darts at a square and circle target as randomly as possible? Physics Girl‘s Dianna Cowern and Veritasium‘s Derek Muller attempt the challenge, and when “randomly” doesn’t happen, they rethink their methods and try again.
Watch what they come up with in this video from March 14 (3/14) 2015: Calculating Pi with Darts.
What is Pi? From PiDay.org:
“Pi (π) is the ratio of a circle’s circumference to its diameter. Pi is a constant number, meaning that for all circles of any size, Pi will be the same.
“The diameter of a circle is the distance from edge to edge, measuring straight through the center. The circumference of a circle is the distance around.”
When rounding, the result is 3.14 or 3.14159 or 3.14159265359, but as The New Yorker explains, “it appears to be an endless number—it has been computed to more than thirteen trillion digits, among which there is no pattern that repeats.”
