What are some best example of 'cleverness' in history?

 In ancient Greece, the renowned mathematician Archimedes showcased remarkable cleverness in problem-solving. King Hiero II sought to determine the purity of a gold crown, and Archimedes ingeniously discovered a method while immersed in his bath. By observing the water displacement caused by the crown, he could accurately assess its gold content. This clever insight not only solved the king's problem but also led to Archimedes' famous exclamation of "Eureka!"

During World War II, the brilliant mind of Alan Turing played a pivotal role in the Allied victory. Turing's cleverness in codebreaking, particularly deciphering the German Enigma code, provided crucial intelligence to the Allies. His groundbreaking work at Bletchley Park significantly impacted the course of the war, showcasing the power of intellectual cleverness in the face of adversity.

The Renaissance polymath Leonardo da Vinci exemplified cleverness through his myriad inventions and conceptual designs. His notebooks reveal an extraordinary breadth of innovative thinking, encompassing flying machines, anatomical studies, and artistic techniques. Da Vinci's clever insights transcended traditional boundaries, leaving an indelible mark on fields ranging from engineering to the arts.

In the realm of military strategy, the Trojan Horse remains an iconic example of clever tactics. During the Trojan War, the Greeks devised a cunning plan by constructing a massive wooden horse concealing soldiers within. Presented as a gift, the Trojans brought the horse into their city, unwittingly allowing the Greek soldiers to emerge and conquer Troy. This clever ruse became a legendary example of strategic thinking and deception in warfare.
