Numerus Aureus |

|
The
mineral world is governed by the irrational numbers, like the square
root of 2 or 3; and the world of the living, by the numbers of the
recurrence sequences such as Fibonacci, Lucas or Pell numbers which
are related to the Golden Number or Phi (F).
There is no magic, the Golden Ratio is an economical way to orchestrate
harmoniously living volumes, with less effort and maximum efficiency. |

Fibonacci
Numbers
There
are a lot of interesting recurrence sequences, but the most popular
one is the Fibonacci sequence. Every number or term of this sequence
is the sum of the two direct preceding terms:
Fn + Fn+1 = Fn+2
and lim. n to infinite: Fn / Fn-1
= 1.618... or Phi. |

Paradoxical
games
Our
Quadrix
Puzzles are based on the Fibonacci or Lucas numbers and on the
golden ratio. When several pieces of these puzzles are permuted,
a small square hole appears... It
is an old mathematical trick which deceives our visual perception. |
With
4 terms of the Fibonacci and Lucas sequences, such as 3, 4, 5, and
7, we can build the base of a paradoxical puzzle
