Genius facts about great inventions
The cardboard box was invented in England in 1817 and initially used for board game pieces. The corrugated cardboard used for shipping boxes was patented in 1871 for wrapping glassware. Today, over 400 billion cardboard boxes are made each year worldwide. Cardboard packaging is one of the most recycled materials on Earth, with recovery rates as high as 90% in some countries.
Nuclear power plants generate electricity using the heat from controlled nuclear fission — the splitting of uranium or plutonium atoms. The first full-scale nuclear power plant to generate electricity for public use opened in Obninsk, Soviet Union, in 1954. Today, nuclear power provides about 10% of the world's electricity and produces virtually no carbon emissions during operation.
The first mechanical clocks appeared in Europe around 1300 AD, using a falling weight to drive gears and a swinging escapement to regulate the speed. Before mechanical clocks, people used water clocks, sundials, or simply the position of the sun to track time. Mechanical clocks transformed daily life by standardizing time and making precise scheduling possible across society.
IBM's chess-playing supercomputer Deep Blue defeated world chess champion Garry Kasparov in a match in 1997 — the first time a computer had beaten a world champion under standard tournament conditions. Kasparov claimed the computer must have had human help, which IBM denied. The match is considered a historic milestone in the history of artificial intelligence.
Geckos can walk upside down on smooth surfaces thanks to millions of microscopic hair-like structures on their feet that create van der Waals forces — weak molecular attractions that add up to a powerful grip. Scientists have developed synthetic gecko-inspired adhesives that can support the weight of a person standing on glass. Unlike glue, these adhesives can be removed and reapplied many times.
Bakelite, the world's first fully synthetic plastic, was invented in 1907 by Belgian-American chemist Leo Baekeland. Made from phenol and formaldehyde, it was heat-resistant and did not conduct electricity, making it perfect for electrical insulation and consumer goods. Early Bakelite radios, telephones, and kitchenware are now collectible antiques.
Electric cars are not a modern invention — the first practical electric vehicle was built in Scotland in the 1880s, and by 1900, electric cars outsold gasoline vehicles in the United States. They fell out of favor when cheap oil and the electric starter made gasoline cars more practical. The modern electric vehicle revival is driven by advances in lithium-ion battery technology pioneered in the 1970s-1990s.
When Bayer began mass-producing aspirin in tablet form in 1900, it became the world's first blockbuster drug. Before this, most medicines were custom-mixed by pharmacists or herbalists. The standardized aspirin tablet introduced the concept of a reliable, consistent drug dose that could be manufactured at scale and sold worldwide — a model that forms the basis of the modern pharmaceutical industry.
The barometer was invented in 1644 by Italian physicist Evangelista Torricelli, who was studying why suction pumps couldn't lift water more than about 34 feet. His experiment with mercury revealed that air has weight and exerts pressure. The barometer not only enabled weather forecasting but proved for the first time that a vacuum — long considered impossible — could actually exist.
Michael Faraday invented the electric generator in 1831 by demonstrating that moving a magnet through a coil of wire produces an electric current. This discovery of electromagnetic induction is the principle behind every electric generator and transformer in the world today. Without Faraday's discovery, modern electrical civilization — power plants, motors, transformers — would be impossible.
