## 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. 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 2. What is the earliest known reference to pi? the Rosetta Stone, inscribed in approximately 200 BC a Middle Kingdom papyrus scroll, written around 1650 BC by Ahmes the scribe Euclid's Elements, written in the 3rd century BC The Uselessness of Pi and its Irrational Friends, written in 1994 AD the Bible 3. For many years, it has been conjectured but unproven that pi is normal in base 10. What does normal mean? Like any normal person, pi has two legs. Blocks of digits of increasing size have a limit frequency of 1/10 for each of the digits (0 to 9). Pi squared is a rational number. People who like pi are normal. The natural logarithm of pi taken to the tenth power is an integer. 4. Among the digits of pi currently known, the concentrations of each of the digits 0 - 9 are pretty much equal. However, in the first 30 digits of pi's decimal expansion, one number is conspicuously missing. Which number is it? 7 2 0 8 6 5. The world pi-recitation record is held by Chao Lu of China. He was able to recite pi from memory to approximately how many decimal places? Six thousand. Seventeen million. Three hundred fourteen thousand one hundred fifty nine. Five hundred. Sixty-eight thousand.
