Wonder of Phi
5 September, 2006
New found knowledge of the golden mean, divine proportion, & the golden section based on the Greek number Phi began a new world of fascination for me. If I could study this for more than one lifetime, I doubt I would ever understand the essence of it’s existence. Primarily, I was interested in how the concepts related to composition in visual art.
This led me to the Fibonacci series of numbers which have been around for a long time. You can read more about it here and here. The first awareness of this was recorded in Sanskrit somewhere between 450 and 200 BC. Yet they were named after the greatest mathematician of the middle ages, who first investigated this concept.

L. Fibonacci was responsible for replacing the Roman Numeral System in Europe with the number system we use now. This is how the numbers occur: 0, 1, 1, 2, 3, 5, 8, 13, … you just add the last two to get the next and so on. Then there is the Golden string of numbers, whose sequence never repeats.
If I understood mathematics, which I don’t have a hope of, then I might technically understand the equations and geometry of the Fibonacci numbers. Everything in the universe appears to be based on and matches this series of numbers. One does not need to understand the technical approach to see the results.

I am awestruck at the way these numbers reoccur in nature. Flowers contain the golden ratio with their petal and seed, leaf arrangements and spirals. Sea shells, tree branches, pine cones, pineapples, apples, are other examples to see how this plays out. This is prevalent in the family trees of many animals as well.
Each division of nature correlates with its surrounding environment. Different types of flowers are connected, one flower beginning the series, connecting with the next flower in order to continue the sequence. Even the reproduction patterns of animals, the human form, music, poetry follow the Fibonacci series. The list goes on, as does the golden string which reaches to infinity and beyond.
A lot of fuss has been made since Dan Brown’s Book, “The DaVinci Code” was written and consequently made into a film. However this is only briefly mentioned in the book. I had been researching this before I was even aware of the book.
Debates have raised the question of whether or not, past masters in music and art used this framework of numbers in their creations consciously. Examples are DaVinci, Mozart, and many more. I would like to suggest this happened intuitively as opposed to being a result of a mathematical approach.
The point for me in studying this, was the hope it would make me a better artist. I have always wanted to know what is going on behind the scenes, in order to gain a larger understanding. If I knew how forms and details occurred in nature then I could apply this to my art. So if I was painting a sunflower, I would know how many petals it should have, and so on.
One can ask why is this so. Yet the harmony and beauty of nature just is. Looking at this, I can scarcely doubt that a supreme being was responsible for all of creation. We are merely part of a larger picture we may never understand. So let us just bask in the wonderment of all that surrounds us, while seeking comfort in the natural order of things.
Study nature, love nature, stay close to nature. It will never fail you. ~Frank Lloyd Wright

I heard about the golden mean from my friend Catherine Neily who is an accomplished photographer, as well as my dear friend and neighbour.
However, I didn’t quite have the understanding you explained above. Thanks for that, as well as the rest of your infomrative posts.
Write and please click on and continue to enlighten us with your work.
Much affection and appreciation,
neil

Brilliant Blog. Your blog has become my favourite hang-out place.
Just for your Information some say that work started in Sanskrit somewhere between 450 and 200 BC on numbers led to huge contribution by Aryabhatta
Aryabhata was the first in the line of brilliant mathematician-astronomers of classical India, whose major work was the Aryabhatiya and the Aryabhatta-siddhanta. Aryabhatiya was a notable work and has influenced the development of mathematics and astronomy in India to a great extent. Many commentaries have been written on it. It lead to the establishment of what is known as Aryabhata School. None of the copies of Aryabhata-Siddhanta is known to exist today. But a small portion of this, consisting of 34 verses have been quoted by others and these deal with the design and construction of astronomical instruments. He also created the Sanskrit numerals.
Pi as Irrational
Aryabhata worked on the approximation for Pi, and may have realized that π is irrational. In the second part of the Aryabhatiya (gaṇitapāda 10), he writes:
chaturadhikam śatamaśṭaguṇam dvāśaśṭistathā sahasrāṇām
Ayutadvayaviśkambhasyāsanno vrîttapariṇahaḥ.
“Add four to 100, multiply by eight and then add sixty-two thousand. By this rule is the circumference of a circle of diameter 20,000 approximately given”
In other words, \pi \approx 62832/20000 = 3.1416, correct to four rounded-off decimal places. The commentator Nilakantha Somayaji, (Kerala School, 15th c.) has argued that the word āsanna (approaching), appearing just before the last word, here means not only that this is an approximation, but that the value is incommensurable (or irrational). If this is correct, it is quite a sophisticated insight, for the irrationality of pi was proved in Europe only in 1761 (Lambert).

Sureshg, I have been enjoying your blog as well.
I have barely chipped the surface, yet I will be visiting as often as I can to catch up on previous posts.
Thank you for your input. You are certainly very knowledgeable about this subject. It looks as though you are fluent in Sanskrit as well.
Aryabhata was most certainly very accomplished, and obviously ahead of his time. Another great wonderment.
Despite the loss of the Aryabhata-Siddhanta, somehow they have survived the test of time. Such is the tendency of these sorts of things.

[...] Wonder of Phi Science meets art and both are beaten soundly by maths in this post on the constant Phi, which is a constant and irrational number that keeps cropping up in nature. The video above is Pi rather than Phi, because as far as I know no-one has made a pop song about Phi. Donations in hard currency will ensure I don’t try and write one. [...]

Thank you for visiting. It can be very confusing this phi/pi thing. Now, are you absolutely certain you didn’t write that song?
(I was trying to post a comment on your blog, and it wouldn’t show up. I tried three times.)
