Euler’s identity is an equality found in mathematics that has been compared to a Shakespearean sonnet and described as " the most beautiful equation." It is a special case of a foundational ...

Leonhard Euler, one of the greatest mathematicians of all time, was born 300 years ago on April 15, 1707.

Arguably, his most notable contribution to the field was Euler’s identity formula, (eiπ + 1 = 0) Euler also made contributions in the fields of number theory, graph theory, logic, and applied ...

When invited to elucidate its meaning, the visitor just chuckled. In fact, this equation, familiar to mathematicians and greatly admired for its elegance, is known as Euler’s Identity.

A stretch too far, perhaps, but Nahin’s tale of the formula ei π + 1 = 0, which links five of the most important numbers in mathematics, is remarkable.
