DailyDirt: Happy Pi Day
from the urls-we-dig-up dept
Math geeks rejoice! It’s Pi Day again! Why is the number pi so awesome? Because, as Mr. Spock once explained, “the value of pi is a transcendental figure without resolution.” Here are a few more cool pi-related links.
- On March 14, 1:59 pm, the Exploratorium in San Francisco (which invented Pi Day in 1988) will be featuring an art installation called “Pi In The Sky.” Created by artist ISHKY with the help of a team of artists, designers, and scientists, “Pi In The Sky” will be visible in the sky at more than 10,000 feet over San Francisco. Five synchronized planes equipped with dot matrix technology will skywrite the first 314 numbers of pi, with each number measuring over a quarter-mile in height. [url]
- How “old” is pi? The ancient Babylonians were able to come up with a close approximation of pi (3.125) around 2000 B.C. [url]
- How many digits of pi are required to be able to measure the circumference of the observable universe, with an accuracy of less than the width of a hydrogen atom? The answer is… 39. [url]
