Fibonacci: It's as easy as 1, 1, 2, 3
We learn about the Fibonacci numbers, the golden ratio, and their relationship. We derive the celebrated Binet's formula, an explicit formula for the Fibonacci numbers in terms of powers of the golden ratio and its reciprical.

Identities, sums and rectangles
We learn about the Fibonacci Q-matrix and Cassini's identity. Cassini's identity is the basis for a famous dissection fallacy colourfully named the Fibonacci bamboozlement. A dissection fallacy is an apparent paradox arising from two arrangements of different area from one set of puzzle pieces. We also derive formulas for the sum of the first n Fibonacci numbers, and the sum of the first n Fibonacci numbers squared. Finally, we show how to construct a golden rectangle, and how this leads to the beautiful image of spiralling squares.

The most irrational number
We learn about the golden spiral and the Fibonacci spiral. Because of the relationship between the Fibonacci numbers and the golden ratio, the Fibonacci spiral eventually converges to the golden spiral. You will recognise the Fibonacci spiral because it is the icon of our course. We next learn about continued fractions. To construct a continued fraction is to construct a sequence of rational numbers that converges to a target irrational number. The golden ratio is the irrational number whose continued fraction converges the slowest. We say that the golden ratio is the irrational number that is the most difficult to approximate by a rational number, or that the golden ratio is the most irrational of the irrational numbers. We then define the golden angle, related to the golden ratio, and use it to model the growth of a sunflower head. Use of the golden angle in the model allows a fine packing of the florets, and results in the unexpected appearance of the Fibonacci numbers in the sunflower.

Excellent exposition of a fascinating subject.\n\nVery well organized, including a handout with the course material.\n\nMany thanks to Prof. Chasnov and the HKUST for this worthwhile opportunity!
por AKMar 22, 2019
Absolutely loved the content discussed in this course! It was challenging but totally worth the effort. Seeing how numbers, patterns and functions pop up in nature was a real eye opener.
por DLSep 28, 2019
I really enjoyed this class. The video lectures were clear and fascinating, and the math assignments were well-chosen and reinforced learning of the material presented in the lectures.
por BSAug 29, 2017
Very well designed. It was a lot of fun taking this course. It's the kind of course that can get you excited about higher mathematics. Sincere thanks to Prof. Chasnov and HKUST.
por HJDec 3, 2016
Good course for introduction to Fibonacci Numbers. Should include more introduction lectures such as group theory, category theory, type theory, number theory, and algorithms.
por UBJun 5, 2018
This course blends the rational thinking of mathematics and the aesthetics of art in nature. Enjoyed it. Thanks Coursera and Hong Kong University of Science and Technology
por CKMar 14, 2017
Thoroughly enjoyed this course. Interested in the Fibonacci Numbers and Golden Ratio and was looking for more information, this was clearly provided.
por BRFeb 18, 2020
Nice course to explore concepts like Fibonacci NUMBERS, Golden RATIO ,Lucas NUMBERS and many more. Very well taught by professor JEFF CHASNOV.
por TSJul 14, 2019
Fantastically explained, and very helpful when difficult in parts. Would recommend to anyone who is interested in maths, not just Fibonacci.
por NEMay 29, 2019
One of the many marvels of mathematics is that of the Fibonacci Numbers & the Golden Ratio.\n\nWeek 2 was somewhat challenging, but doable.
por MCJan 16, 2019
Fascinating course about a topic that is not usually taught in maths lessons. It is easy to follow and it has good supporting material.
por RAApr 3, 2020
Got more information about fibonacci sequence and how it is connected to nature and much more... Maths is really fun and interesting.
por HSSep 12, 2016
Very intriguing and interesting lectures. These got me thinking and venture into Fibonacci numbers and a bit of sacred geometry too.
por VAFeb 27, 2020
A good course on an interesting topic. Instruction is clear, concise and simple. Many practice sums provided to reinforce learning.
por MVJun 18, 2017
Very diverse and interesting course. Lot's of fields in mathematics are discussed. Very nice assignments and super cool teacher.
por TKJul 3, 2017
A thoroughly enjoyable course, a bit too fast paced and quite difficult some times, but the overall course is quite exciting.
por NJAug 3, 2019
I really loved this course. Amazing mathematics that was taught very well and also helped me build my mathematical skills.
por DNJun 24, 2019
Yeah, the course was fun and i knid of learned a lot of new stuff and I'm satisfied with that.\n\nGood course to learn.
por MCApr 1, 2020
Concepts were well explained and easy to understand. I enjoyed how the applications were woven together with the math
por CSApr 28, 2019
Thanks for this wonderful course, Jeff. Those Fibonacci are amazing. I hope you will give us even more MOOCs.
