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. For many years, it has been conjectured but unproven that pi is normal in base 10. What does normal mean?




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?




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




4. One way to approximate the value of pi is to have a computer pick two random numbers, x and y, each between -1 and 1. If it does so N times, and if, for M of those times x^2 + y^2 < 1, then pi is approximately equal to 4*M/N (presumably becoming more accurate as N increases). This method of approximation is an example of:




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?
