The Pi Trivia Game

Home : Pi : The Pi Trivia Game

Finally this is your chance to pay tribute to the magnificent transcendental number that we have all grown to love! Here are 25 questions (given to you 5 at a time), picked randomly from my pi question database. Get ready for the thrill of your lifetime, the ultimate challenge, The Pi Trivia Game!

1. If you pick any two integers at random, what is that probability that they will be relatively prime? ("relatively prime" means that the two numbers share no divisors except 1)

pi/2
pi/3
1/pi
6/(pi^2)
pi^2/9

2. The physicist Willebrord Snellius (1580-1626) found polygons which better approximated the perimeter of circles than do inscribed and circumscribed polygons. Better perimeter approximations lead to more quickly converging pi approximations. What scientific discovery is Snellius best known for?

the laws of reflection and refraction
general relativity
exploding pop-tarts
the photoelectric effect
the uncertainty principle in quantum mechanics

3. Are pi's digits periodic?

Yes; the digits repeat themselves after every 6000 decimal places.
No; only women, not numbers, are unfortunate enough to be periodic.
Maybe; not enough digits of pi have yet been calculated to know if they start eventually repeating themselves.
Yes; every infinitely long number has to start repeating itself sometime.
No; every periodic number is rational, but pi is irrational.

4. What professor was dismissed from his position in 1934 for teaching in an "un-German" style after saying (correctly) that pi/2 is the value of x between 1 and 2 for which cos x vanishes?

J. Robert Oppenheimer
Kip Thorne
Scott Adams
Elias Bröms
Edmund Landau

5. For a given value of N: if you add up the first N decimals of pi (excluding the initial 3), the sum is 666 (not to imply that pi is at all satanic). What is the value of N?
