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. Simon Plouffe has recently derived an algorithm for calculating pi in hexadecimal. Remarkably, this formula allows one to calculate the nth decimal of pi without calculating the previous digits. Incidentally, Plouffe was listed in the 1975 Guinness Book of World Records. For which of the following accomplishments was he listed?




2. Pi shows up many places in physics, including simple harmonic motion. Given a simple pendulum of length h, what is the period for a small oscillation (the period is the time it takes to complete one full oscillation)?




3. Which of the following is an arctangent formula for pi?




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?




5. 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)
