Pi - Totally Irrational Pi -- such a simple concept, yet it's a number that cannot be represented as a fraction a/b, where a and b are integers. That means it's Totally Irrational! |

Gravity by Newton Sir Isaac Newton revolutionized astronomy and physics with his formula for gravity in 1687. |
Phi - the Golden Ratio Phi, the Golden Ratio, was used in architecture and in art because it was found to be a pleasing relationship. That may be true, but I think that it's totally irrational! |

i - Use your Imagination! What's more "irrational" than irrational numbers? The square root of -1 seems that way. It's an "imaginary" number, and the source of complex numbers. Imaginary, complex, what more could you ask? |
