# Week 03 – Core Principles

October 21, 2020 - Blogs

In week 3 we looked at a range of core design principles which we can use to develop the foundations upon which we can build. This included the Golden Ratio which is a prime example of the Fibonacci sequence. The Fibonacci sequence exhibits a certain numerical pattern which originated as the answer to an exercise in the first ever high school algebra text. This pattern turned out to have an interest and importance far beyond what its creator imagined. It can be used to model or describe an amazing variety of phenomena, in mathematics and science, art and nature. The mathematical ideas the Fibonacci sequence leads to, such as the golden ratio, spirals and self- similar curves, have long been appreciated for their charm and beauty, but no one can really explain why they are echoed so clearly in the world of art and nature.

The golden ratio is sometimes called the “divine proportion,” because of its frequency in the natural world. The number of petals on a flower, for instance, will often be a Fibonacci number. The seeds of sunflowers and pine cones twist in opposing spirals of Fibonacci numbers. Even the sides of an unpeeled banana will usually be a Fibonacci number—and the number of ridges on a peeled banana will usually be a larger Fibonacci number. The image here was created in Figma. This was from a class exercise which we were given the task of creating two points in three different patterns using the Fibonacci sequence as a way of structuring the content. Another class exercise we had was to create a simple layout of three favourite apps using planes. I chose Snapchat, Facebook and YouTube. I created them in Figma.
