http://bitly.com/architectsacademy The Fibonacci Sequence, The Golden Rectangle and Architecture pt.1. In 1202 Leonardo Fibonacci was famously investigating rabbit reproduction and made note of a sequence that is now know as his namesake – The Fibonacci sequence. The sequence is 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, et cetera. It is derived by adding each number to the previous, e.g. 1 + 1 = 2, 1+2 3, 2 + 3 = 5. Plant leaves as they spiral around a stem, called (phyllotaxis), in some cases follow a mathematical rhythm of 1.618. The same spiraling numberical rhythm seen on the skin of a pineapple as well as the seed head arrangement of the sunflower, and the base of a pinecone. In geometrical terms if a rectangle is drawn with one side equal to 1 and its perpendicular side represented as 1.618, a desirable shape emerges. In 1876 Gustov Fechner did a study that determined that people visually preferred the shape to other rectangles. It’s thought that the ratio may have been used as early as the Egyptians in the creation of the great pyramids. In fact, It’s probably true. Based on measurements of the Pyramid at Giza the hypotenuse almost precisely matches the number phi or 1.618. It’s also thought that Andrea Palladio employed the golden ratio proportions. This is his Villa Rotonda outside Vincensa in northern Italy. Even the modern architect Le Corbusier used the proportions in his modular man study and, most likely, to design his Unite d Habitation in Marseilles France.

1. You might like this, My Fibonacci small house experience. One night I drank a few too many beers. Enjoy :)

2. Thanks, really useful for handling Steel Balls and fingernails.
3. Who is here because of a school assignment? I am
4. Who was the golden salamander?
5. Just two things I want to point out (trivial and perhaps pedantic, but whatever):
   
   1.) The Fibonacci and golden spirals only approximate one another. They are by no means the same. Construction of these spirals would show the clear differences.
   2.) One of Gustav Fechner's biggest goals (indeed the end goal of a good deal of his work) is to prove how plants have souls.
6. the golden point of the earth is Kaaba
    
7. most of my friends dont even know using this for design application. 
   
   so they just copy some famous building plans or forms from a work compilation book, change some window placement and gets an A, 3.5+ GPA for their semester. Way easier lol.
   
   im stuck here with a C+ trying to go deep doing designs from scratch. life sucks.
8. korboesiejee
9. O.O
10. COOL
11. Why the heck I can not view any of your videos, this isn't fair. Why doesn't it permit bulgarians? :/
12. Teach us how to become architects without school!
13. Pretty cool video. I've been subscribed to you for a while now, but coincidentally In one of my classes this morning we went over the Fibonacci sequence..it never ceases to amaze me
14. Great video!
15. I would love for you to do a video about the relationship acoustics has with architecture and its importance within the field.
16. why i cant view the videos , it says it isnt available in my countery (saudi arabia)
17. I recently started following your channel, and there are so many cool things I would like to know your opinion on, like a video on the work of Gio Ponti (who made some really interesting houses here in Venezuela) or a video on light and how to seize and play with it in the construction of spaces...
18. Cant view 5 other videos?
