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]

Awww damnit! I thought it was... 42.

But you will need one HELL of a long tape measure
motto of the story, you need a ruler to measure distance, not a number.

now if you were trying to calculate the circumference by measuring the diameter, and doing a further calculation you would require the value of pi..
if you want to CALCULATE the circumference of the universe by measuring the diameter then pi is needed.
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,
ZERO digits.. of pi are required to measure it's circumference.. and 1 very long tape measure.

Re:
if you were trying to measure it's diameter, you then would need pi to 39 decimal places to calculate it's circumference from your measurement of it's diameter.
it is not possible to measure the diameter to that accuracy.
zero digits of pi are required if you are directly measuring it's circumference.

Pi Day?
You ask, what is Tau day?
http://halftauday.com/
Hope you will publish Tau day on 6/28 too. After all Pi is simply half of Tau.

I decide to use the unit of measurement, not inches, feet, miles or light-years, instead I will use as my unit length Universe Diameters, therefore the circumference of the universe (assuming it is round), equals 3.1415..... Universe diameters.
circumference of universe = 3.1415UD's (Universe diameters). To an infinite precision.

Re: Re: Pi Day?
Wait, that can't be right. I don't recall the planet being called Lythion in the movie. Only on the DVD cover.
