Many works of art are claimed to have been designed using the golden ratio. However, many of these claims are disputed, or refuted by measurement. [1] The golden ratio, an irrational number, is approximately 1.618; it is often denoted by the Greek letter φ .
The golden ratio φ and its negative reciprocal −φ −1 are the two roots of the quadratic polynomial x 2 − x − 1. The golden ratio's negative −φ and reciprocal φ −1 are the two roots of the quadratic polynomial x 2 + x − 1. The golden ratio is also an algebraic number and even an algebraic integer.
A photography game is a video game genre in which taking photographs using the in-game camera system is a key game mechanic.Photography games often employ mechanics similar to a first-person shooter, but rather than using a gun to kill enemies, the goal is to use a camera to take photographs of things in the game world. [1]
Some examples of organisms in published studies of the golden ratios: The nautilus, the human body proportion, the reproduction of rabbits (Fibonacci started by observing the rabbits), the reproduction of cows (Henry E. Dudeney), the number of petals in flowers, the sunflower spirals, the pine cones, species of Radiolaria (shaped like polyhedra ...

After Pacioli, the golden ratio is more definitely discernible in artworks including Leonardo's Mona Lisa. [55] Another ratio, the only other morphic number, [56] was named the plastic number [c] in 1928 by the Dutch architect Hans van der Laan (originally named le nombre radiant in French). [57] Its value is the solution of the cubic equation ...
where F n is the nth Fibonacci number. The ratio of numbers of kites to darts in any sufficiently large P2 Penrose tiling pattern therefore approximates to the golden ratio φ. [47] A similar result holds for the ratio of the number of thick rhombs to thin rhombs in the P3 Penrose tiling. [45]
