Sparks That Changed the World
The Discovery of Fire
The ability to create fire was a pivotal skill for early humans, who learned to produce sparks by striking stones together or generate heat through the friction of rubbing sticks. This innovation played a significant role in human evolution.
Years Ago
The Discovery of Gunpowder
Chinese alchemists inadvertently invented gunpowder when they combined sulfur, charcoal, and saltpeter, with the mixture probably being ignited by sparks. This invention dramatically changed the trajectory of world history by facilitating the ascent and descent of empires.
The Discovery of Radio Waves
Heinrich Hertz discovered radio waves by demonstrating their existence through experiments with spark-gap transmitters. This laid the foundation for the development of wireless communication, which revolutionized global communication and technology.
Innovations in AC Electricity
Nikola Tesla, renowned for his impressive electrifying coils, received multiple patents for his alternating current (AC) designs and played a pivotal role in the widespread adoption of AC as the preferred electrical power distribution system, surpassing the far riskier direct current (DC) systems developed by Thomas Edison.
