On January 3, 1496 AD, Leonardo da Vinci experienced a setback in his pursuit of flight, as his self-designed flying machine failed during its first test. This early challenge didn’t define the Italian Renaissance master, however, and serves as a potent reminder that innovation often arises from initial failures.
Leonardo da Vinci
Da Vinci’s fascination with aviation wasn’t born from abstract thought, but from meticulous observation of the natural world. He keenly studied the mechanics of bird flight, dissecting their movements and documenting his findings in now-famous notebooks. These studies led to designs for various flying machines, including the ornithopter – a plane with flapping wings intended to mimic birds – as well as glider-like concepts and even an early conceptualization of the helicopter, known as the air screw.
Despite his visionary designs, practical limitations hindered da Vinci’s aviation project. The absence of lightweight engines, insufficient materials, and an incomplete understanding of aerodynamics at the time proved insurmountable obstacles. Yet, the true significance of da Vinci’s efforts lies not in achieving flight, but in his methodical, observation-based approach to problem-solving.
Thomas Edison
Early in life, Thomas Edison faced criticism from a schoolteacher who deemed him “depraved” due to his frequent daydreaming. However, this didn’t derail his path to becoming a prolific inventor. Edison credited his mother, who homeschooled him, and his reading of Parker’s The School of Natural Philosophy for fostering his education. He fondly recalled, “My mother was the one who made me. She had confidence in me. At that time, I felt that my life had a purpose, and a person whom I could not let down.”
Edison also battled hearing problems from a young age, stemming from repeated bouts of scarlet fever and untreated ear infections. He later attributed the cause to a train conductor lifting him by his ears as a child. Despite these challenges, Edison persevered, ultimately securing 1,093 patents.
Before achieving fame, Edison experienced financial hardship, working as a vegetable seller. In 1854 AD, he sold candy and vegetables on trains in Michigan, and later secured exclusive rights to sell newspapers along a rail line, launching a weekly bulletin with four assistants. This venture marked the beginning of his entrepreneurial career, eventually leading to the establishment of 14 companies.
