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. 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)?




2. If one were to find the circumference of a circle the size of the known universe, requiring that the circumference be accurate to within the radius of one proton, how many decimal places of pi would need to be used?




3. Which French mathematician said in 1909 that it is hopeless to think that we could ever check if there are 10^100 consecutive zeroes in the decimal expansion of pi?




4. 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?




5. At which decimal of pi does the earliest occurrence of the string 999999 begin?
