## What is a Fibonacci clock?

The screen of the clock is made up of five squares whose side lengths match the first five Fibonacci numbers: 1, 1, 2, 3 and 5. The hours are displayed using red and the minutes using green. When a square is used to display both the hours and minutes it turns blue. White squares are ignored.

**How does Fibonacci spiral clock work?**

The clock works by combining a spiral arm, designed using a Golden Ratio rectangle or a rectangle comprising contiguous squares whose sides are Fibonacci numbers (i.e. the same thing).

**Is the Fibonacci sequence applicable in real life?**

We observe that many of the natural things follow the Fibonacci sequence. It appears in biological settings such as branching in trees, phyllotaxis (the arrangement of leaves on a stem), the fruit sprouts of a pineapple, the flowering of an artichoke, an uncurling fern and the arrangement of a pine cone’s bracts etc.

### Which kind of electric clock uses a row of numbers to tell the time?

The Fibonacci clock lets you know the time more subtly, by changing colours and requiring you do some adding up. Philippe Chrétien from Montreal, Canada, noticed that these numbers are all you need to express all the numbers from 1 to 12.

**Why does the number on a clock add up to 13?**

Harry from the Beacon School solved this using an algebraic method. The sum of all the numbers is 78. If we call x the total on the small side, then 5x+x=78, so 6x=78 and x=13. So the sum on the small side is 13.

**How is Fibonacci used in everyday life?**

leaf arrangement in plants, to the pattern of the florets of a flower, the bracts of a pinecone, or the scales of a pineapple. The Fibonacci numbers are therefore applicable to the growth of every living thing, including a single cell, a grain of wheat, a hive of bees, and even all of mankind.

#### Why Fibonacci is related to golden ratio?

The golden ratio describes predictable patterns on everything from atoms to huge stars in the sky. The ratio is derived from something called the Fibonacci sequence, named after its Italian founder, Leonardo Fibonacci. Nature uses this ratio to maintain balance, and the financial markets seem to as well.

**Where can you find the Fibonacci sequence in nature?**

The Fibonacci sequence in nature We can easily find the numbers of the Fibonacci sequence in the spirals formed by individual flowers in the composite inflorescences of daisies, sunflowers, cauliflowers and broccoli.

**Is golden ratio and Fibonacci the same?**

The golden ratio is about 1.618, and represented by the Greek letter phi, Φ. The golden ratio is best approximated by the famous “Fibonacci numbers.” Fibonacci numbers are a never-ending sequence starting with 0 and 1, and continuing by adding the previous two numbers.
