Until a few months after taking this picture, I did not realize that I had photographed something similar to the "Fibonacci Spiral" on the interior staircase of the Uxama lookout tower.
The similarity is almost perfect.
The interior staircase that gives access to the top of the watchtower of Uxama.
The Watchovers were built with a certain abundance in the Middle Ages in Spain to mark the borders.
They served to warn of the arrival of enemy armies.
There were different types of visual signals to communicate with each other.
The Watchover in this picture is strategically located on the hill where the ancient Iberian and then Roman city of Uxama was located, which gave name to the cities of Osma and El Burgo de Osma in Soria, Spain.

LA ESPIRAL DE FIBONACCI EN LA ATALAYA DE UXAMA. 2017
Hasta unos meses después de hacer esta foto, no me di cuenta de que había fotografiado algo parecido a la "Espiral de Fibonacci" en la escalera interior de la atalaya de Uxama.
El parecido es casi perfecto.
La escalera interior que da acceso a la parte superior de la atalaya de Uxama.
Las atalayas se construyeron con cierta abundancia en la Edad Media en España para marcar las fronteras.
Sirvieron para avisar de la llegada de ejércitos enemigos.
Había diferentes tipos de señales visuales para comunicarse entre sí.
La atalaya de esta imagen está situada estratégicamente en el cerro donde se encontraba la antigua ciudad ibérica y luego romana de Uxama, que dio nombre a las ciudades de Osma y El Burgo de Osma en Soria, España.

We see the fibonacci sequence in the whorls of our fingerprints, the curve of waves, the shells of the nautilus, and the center of sunflowers. It governs the double helix of our DNA. And I found it in this little cactus in the Arid Conservatory at the Frederick Meijer Gardens and Sculpture Park.
From the link: "Sunflowers have a Golden Spiral seed arrangement. This provides a biological advantage because it maximizes the number of seeds that can be packed into a seed head."
La naturaleza, contra lo que pueda parecer, no se organiza de forma caótica. La floración del girasol es un ejemplo excelente en este sentido.
Las flores se distribuyen curiosamente en espirales a izquierdas y derechas de forma que el número de unas y otras sigue la sucesión de Fibonacci. En este caso 21 y 34. También podría ser 34 y 55
La sucesión de Fibonacci empieza con un 0 y un 1 y continúa añadiendo números que son la suma de los dos anteriores: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144,...
Fractals show self-similarity, or comparable structure regardless of scale. For example, a small piece of Romanesco broccoli, when viewed up close, looks the same as a larger chunk. In this photo you see buds with spirals that flow in two directions. If you zoom out you again see spirals that flow in two directions.
The branched tips of a bud, called meristems, make up a logarithmic spiral, and the number of spirals on the head of Romanesco broccoli is a Fibonacci number, which in turn is related to what's known as the "golden ratio."
The 13th-century mathematician Leonardo Pisano's nickname was "filius Bonacci" (son of Bonacci), which got shortened to Fibonacci. In his 1202 treatise, "Book of Calculation", Fibonacci described the numerical sequence that now bears his name: 1, 2, 3, 5, 8, 13, 21... and so on, where each number is equal to the sum of the preceding two numbers. Divide each number in the sequence by the one that precedes it, and the answer will be something that comes closer and closer to 1.618, an irrational number known as phi, aka the golden ratio (eg, 5 divided by 3 is 1.666; 13 divided by 8 is 1.625; 21 divided by 13 is 1.615; and so on). And there is a special "golden" logarithmic spiral that grows outward by a factor of the golden ratio for every 90 degrees of rotation, of which a "Fibonacci spiral" is a close approximation.
About this photo: In February I gave a photography class at the Embarcadero in San Francisco on behalf of the Digital Photo Academy. We walked in the halls of the Ferry Building to try one-point perspective shots. Then we went outside to practice rule of thirds and street photography at the Ferry Plaza Farmers Market.
I processed a realistic and a balanced HDR photo from a RAW exposure, blended them selectively, carefully adjusted the color balance and curves, and enlarged the image with Topaz Gigapixel AI. I welcome and appreciate constructive comments.

I have always granted myself the freedom to exercise artistic license and pursue whatever brings me joy. Currently, shots from my cellphone and digital AI artwork fulfill that purpose, at least for the time being.
If in doubt which is my work and which is Generative AI, just look for the watermark on my photography.

This year continues to suprise. Purple cone flowes continue to bloom in the Silo Garden at the Lady Bird Johnson Wildflower Center. I try to take a few photographs before my volunteer gardening shift on Friday. The army of volunteers make the Wildflower Center always beautiful.
I like the near resemblance here to the Fibonacci spiral in the stem, and the stamens discovered in their hiding place.
Is there no end to this obsession with aging tulips? Alas, I fear not my friend. Indeed, several more are currently lined up in the tube awaiting their turn. I hop you haven't tired of them, and I "hop" I learn to type someday.
The much photographed spiral stairs at Citizen M Hotel. Not as many from the top as it involves dangling your camera out into the void.
I prefer the view from the bottom up but I seem to be too incompetent to get an exposure that I'm happy with.
This shot was almost so completely dark as to be ruined, but after the exposure was lifted quite a few stops while processing, an interesting image with quite pleasing colours was revealed.
