## Why They Matter
Nikola Tesla's work fundamentally transformed the way humanity generates, transmits, and utilizes electrical energy. By championing alternating current (AC) over direct current (DC), he enabled the efficient long-distance transmission of electricity, which is the backbone of the modern power grid. His inventions, such as the induction motor and the Tesla coil, remain critical components in industrial machinery, radio technology, and high-voltage applications today. Furthermore, his visionary concepts regarding wireless communication and energy transmission anticipated the development of radio, radar, and modern wireless power technologies. Without his contributions, the rapid industrialization of the late 19th and early 20th centuries would have been significantly delayed, and the technological landscape of the 21st century would be unrecognizable.
