Refrigerator
In 1876, German engineer Carl von Linde developed a more efficient refrigeration system using a compression-expansion cycle with ammonia as a refrigerant. This innovation significantly improved cooling efficiency, making refrigeration practical for industrial use and food preservation. Von Linde’s work laid the foundation for modern refrigeration technology, which transformed food storage, medicine, and various industries worldwide. -
Invention of the telephone
The telephone was invented by Alexander Graham Bell in 1876. Bell's breakthrough came when he successfully transmitted sound via electrical signals, allowing voice communication over long distances. His first words spoken into the device were, "Mr. Watson, come here, I want to see you." The invention revolutionized communication, shaping modern society and global connectivity. -
Light bulb
The light bulb was famously invented by Thomas Edison in 1879, though several inventors contributed to its development. Edison perfected a practical, long-lasting incandescent bulb by using a carbon filament in a vacuum. His success led to widespread adoption of electric lighting, revolutionizing how people lived, worked, and illuminated their homes, ultimately shaping modern society. -
Internal combustion engine
In 1885, Karl Benz developed the first practical internal combustion engine for his Benz Patent-Motorwagen, widely considered the first automobile. The engine was a single-cylinder, four-stroke design, powered by gasoline. This innovation marked a key moment in automotive history, leading to the development of modern vehicles and changing transportation forever by replacing horse-drawn carriages with motorized ones. -
The first automovile
The first automobile is generally credited to Karl Benz, who built the Benz Patent-Motorwagen in 1885-1886. It was a three-wheeled, gasoline-powered vehicle with a simple internal combustion engine. Benz’s invention marked the beginning of the modern automobile industry, demonstrating the potential for self-propelled vehicles, and paving the way for future innovations in transportation. -
The Cinématographe
The Cinématographe, developed by the Lumière brothers in 1895, was an early motion picture camera and projector. It could both film and project moving images, unlike previous devices. Compact and efficient, it revolutionized cinema, allowing for public screenings. The Lumières' first commercial projection in Paris marked the birth of cinema as a mass entertainment medium. -
Invention of the radio
The radio was invented through contributions from multiple scientists, but Guglielmo Marconi is often credited with its practical development. In 1895, he successfully transmitted radio waves over long distances, leading to the first wireless communication. Marconi’s work laid the foundation for radio broadcasting, revolutionizing communication by allowing information and entertainment to be transmitted over vast distances without wires. (the date is for the first transmision) -
Invention of the plain
The first successful powered flight was achieved by the Wright brothers, Orville and Wilbur, on December 17, 1903, in Kitty Hawk, North Carolina. Their plane, the Wright Flyer, flew 120 feet in 12 seconds. The brothers' innovations in control, propulsion, and aerodynamics laid the foundation for modern aviation, transforming travel and shaping the future of air transport.
