Etymology
The symbol for phi, ฮฆ, originated from the Greek alphabet, where it is the 21st letter. The use of phi to denote the golden ratio is attributed to the mathematician Mark Barr in the early 20th century. Before this, the golden ratio was known by different names and discussed in relation to aesthetics and nature for centuries. The appeal of the golden ratio has been a subject of fascination since ancient times, where it was recognized by the Greeks as a ratio that reflected beauty and proportion. Philosophers and mathematicians, including Euclid, Pythagoras, and later Fibonacci, contributed to its understanding. Today, phi is a common topic in discussions on art, mathematics, and design, celebrated for its uncanny resemblance to natural forms.
