Agreed that pi is a quite interesting number, though. Not, perhaps, as interesting as e or phi, but quite interesting nonetheless. As to the original post  gotta be zero. <Comic Book Guy voice> Coolest . . . number . . . ever. Patrick

When I was about 13 I did this on a mathematic lesson, quite fun... I got it from Harry Lorayne´s Magic Book

Landmark suggested the Speed System book a long time ago, I eventually managed to locate a copy (having seached I found it right under my nose at my school library)!
I really advise this as an excellent book! Although not really that magically relevant, if you want to develop your arithmatic skills this is a really excellent system. I cannot claim to have practiced and honed all of the principles, but if you work on it, and spend time, this could be very rewarding. I just enjoyed it as I was interested in trying to work out why this stuff works! Excellent, Owen

There are really TWO most magical numbers, these being: 365 and 366.
365 is the number of days per normal year while 366 is the number of days in a leap year. I believe it was Cassidy who pointed out that the sum of the integers from 1 to 13 (ace to king) is 81. 81 times 4 (being the number of suits) is 364. 364 plus one joker gives 365. 364 plus two jokers gives 366. There are 52 cards to a deck (sans jokers) and 52 weeks per year. There are 13 cards per suit and there are 13 lunar cycles per year. There are 4 suits per deck and there are 4 seasons per year. The number 365 can be derived by taking the gematric value of the Greek name of the Gnostic deity ABRAXAS or ABRASAX. But, to quote Crowley, "Every number is infinite; there is no difference."

Three is a magic number,
Yes it is, it's a magic number. Somewhere in the ancient, mystic trinity You get three as a magic number. The past and the present and the future. Faith and Hope and Charity, The heart and the brain and the body Give you three as a magic number. It takes three legs to make a tripod Or to make a table stand. It takes three wheels to make a vehicle Called a tricycle. Every triangle has three corners, Every triangle has three sides, No more, no less. You don't have to guess. When it's three you can see It's a magic number. A man and a woman had a little baby, Yes, they did. They had three in the family, And that's a magic number. 369, 121518, 212427, 30. 369, 121518, 212427, 30. Multiply backwards from three times ten: Three time ten is (30), three times nine is (27), Three times eight is (24), three times seven is (21), Three times six is (18), three times five is (15), Three times four is twelve, And three times three is nine, and three times two is six, And three times one is three of course. Now take the pattern once more: Three! . . .369 Twelve! . . .121518 Twentyone!. . .212427. . .30 Now multiply from 10 backwards: Three time ten is (30  Keep going), three times nine is (27), Three times eight is (24), three times seven is (21), Three times six is (18), three times five is (15), Three times four is twelve, And three times three is nine, and three times two is six, And three times one... What is it?! Three! Yeah, That's a magic number. A man and a woman had a little baby. Yes, they did. They had three in the family. That's a magic number. Schoolhouse Rock Baby!!!! Vandy

Is 69 a magic number?

Math geeks, you gotta love 'em!
Since the set is so small to choose from I'm going with 3. Has to be prime to be interesting. Trinity, Good things come in three's, famous people die in threes, good things happen in threes. If you're Canadian you probably love Hat Tricks. Octopussess' (or is it octopi?) have 3 hearts. Hayseeds love 3 (I think it has something to do with racing cars). Babe Ruth wore number 3, we live on the third planet from the Sun and in Texas it is illegal to take more than three sips of beer while standing. 'All things thrive but thrice' Scottish Proverb If that wasn't good enough 3!+3=3^2 3 is the only prime whose factorial is a perfect number. 3^3=3^2+3^2+3^2 All sufficiently large odd numbers are the sum of at the most 3 prime numbers. Last but not least, THE THREE STOOGES! By the way, Zero is not a number.

There are a few Fibionacci effects that appear in Martin Gardner's Martin Gardner Presents. They also appear in The James File.
