Leonhard Euler Trivia Questions

In 1736, Euler proved it was impossible to cross all seven bridges exactly once, creating the first graph theory proof.

Euler was born in Basel, Switzerland, but spent the majority of his career at the St. Petersburg Academy in Russia and the Berlin Academy in Germany.

Euler was prolific even after losing his sight in 1771, dictating complex mathematics to scribes. His output actually increased post-blindness.

The Four Color Theorem was conjectured in 1852 by Francis Guthrie, decades after Euler's death. Euler did work on planar graphs, however.

Euler popularized π, but the symbol was first used by Welsh mathematician William Jones in 1706. Euler adopted it later in his 1737 work.

Euler won the Paris Academy's grand prize twelve times, including for his work on lunar theory and ship masts.

Euler first used the notation f(x) in his 1734 paper 'De progressionibus', standardizing how mathematicians denote functions.

René Descartes coined the term 'imaginary numbers' in 1637. Euler introduced the symbol i for √-1 in 1777. Since Euler did not coin the term, the statement is false.
