The Fibonacci Sequence
The Fibonacci sequence is the sequence of integers 0, 1, 1, 2, 3, 5, 8, 13, 21,… or 1, 1, 2, 3, 5, 8, 13, 21, … It is a sequence of numbers that starts with 0 (or 1) and each number is the sum of the previous two. The sequence first appeared in Liber Abaci, a book written by Leonardo of Pisa, more popularly known as Fibonacci.
The sequence appear in many branches as well as in many form. Take for instance the rectangle above. You can create a rectangle whose sides are consecutive numbers of the Fibonacci Sequence. The Fibonacci Sequence also appears in the Pascal’s Triangle. » Read more
Pascal’s Triangle is a triangular array of numbers where each number on the “interior” of the triangle is the sum of the two numbers directly above it. It was named after French mathematician Blaise Pascal.
There are many interesting things about the Pascal’s triangle. In this post, we explore seven of these properties. » Read more
This is a captivating video ‘inspired by numbers, geometry and nature’ and was created by Cristóbal Vila. The video explains the connections between the Fibonacci sequence 1,1,2,3,5,8,13, … (can you see the pattern?), and nature (the golden rectangle, the nautilus, the sunflower, etc.).
For non-math people, you will appreciate this video if you know the concepts behind it.
I came across with this video about two weeks ago, but I had no chance to post it until I was reminded by a post about it at the MathFuture wiki. On the funny side, there were more than 10 thousand who liked the video in Youtube, but 122 disliked it (plus a few more recently). One user (GatorTomKK) had the following comment for those 122 (and possibly for future ‘dislikers‘) :
122 people don’t understand math in general.
I can’t help but grin after reading the comment, and I’m sure your doing the same.
