Learn some math
The human eye finds certain mathematical patterns particularly appealing because of their symmetry
and beauty in proportion. Appearing everywhere in nature, they address the biophilia effect reducing
our stress and increasing our focus and concentration.

Positive psychological responses to images featuring particular math sequences are explained by the
human eye’s and, therefore, brain’s capability to scan and interpret them faster, subconsciously
recognizing them as an expression of perfection.

The Golden Ratio and the Fibonacci Sequence are the top math patterns explaining the idea why visuals
are so powerful and demonstrating it with the rule of thirds.

The Fibonacci sequence
When the next number in the series is the sum of the previous two, we get the Fibonacci Sequence:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, etc…

Here’s how it is figured….
• 0+1 = 1
• 1+1 = 2
• 1+2 = 3
• 2+3 = 5
• 5+3= 8 and so on.

According to Ross Johnson from 3.7 Designs, “the series is one of the leading patterns in both math and
design.”

If you divide any number from the sequence by its forerunner, it
will result in the golden number creating the Golden Rectangle,
a shape present in arts, nature, and architecture.

The golden number is 1.618.
• 8/5 = 1.6
• 5/3 = 1.67
• 3/2 = 1.5

This is how the Fibonacci sequence works in
