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. The following are all mnemonics for remembering the first few digits of pi (the number of letters in each word corresponds to a digit of pi). Which of these was written in 1995 by Michael Keith?




2. In 1949, a digital computer was first used to calculate pi. To how many decimal places was this computer, ENIAC (Electronic Numerical Intergrator and Computer), able to find pi (it took 70 hours)?




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. Consider the following series of natural numbers, constructed by taking successively larger strings of digits from the beginning of the decimal expansion of the number pi:
3, 31, 314, 3141, 31415, 314159, 3141592, etc.
Out of the first 1000 numbers in this series, how many are primes? (for example, the first two numbers, 3 and 31, are both primes)




5. What 1768 proof about pi is the German mathematician Johann Lambert famous for?
