The 1983 film EUREKA is loosely based on the true murder of Sir Harry Oakes in the Bahamas in 1943.
Directed by Nicolas Roeg, it is the story of a Klondike prospector, Jack McCann (played by Gene Hackman) who strikes it rich,
yet ends up fearing that his daughter Tracy (Theresa Russell) and his son-in-law (Rutger Hauer) are scheming to take his wealth and his soul.
Moreover, greedy investors (Joe Pesci and Mickey Rourke) are also hunting McCann's fortune.

GEOMETRY also has strong connection to Eureka. Archimedes (287 BC – 212 BC) coined the term "Eureka" in the nude, when he figured out a way
to determine whether King Hiero II of Syracuse had been duped by measuring the buoyancy of the king's supposedly solid gold crown in water.
In Greek (Archimedes' native language) Eureka means "I have found it".

Archimedes used mathematic principles calculate the areas and centers of gravity of various geometric figures including triangles, parallelograms and parabolas.

Another mathematician, Carl Friedrich Gauss, echoed Archimedes when in 1796 he wrote in his notebook, "ΕΥΡΗΚΑ! num = Δ + Δ + Δ",
referring to his discovery that any positive integer could be expressed as the sum of at most three triangular numbers. This is known as Gauss' Eureka theorem
