Apple is well-known for its love of the so-called golden ratio, an “extreme and mean” mathematical ratio that designers as far back as the third-century B.C. had identified as most likely to lead to harmonious design. The iCloud logo, for example, is designed with the golden ratio in mind… and it’s widely believed that the iconic Apple logo is also designed using the golden ratio.
It’s a nice thought, isn’t it? That Apple’s logo is constructed out of mathematically perfect circles and partial circles? Unfortunately, not only is it not true, but Apple has different logos it uses even in its own official materials: the Apple icon etched into the back of your iPad is very different than, say, the official Unicode symbol.
