LASERLASER’s allow light to be intensely focused. There are many uses, from reading digital media at low power to cutting at higher powers. Countless applications rely on LASER technology. In 1957, Arthur Schawlow and Charles Townes, of Bell Labs, worked on an infrared LASER, called an “optical MASER.” They patented the invention in 1958. In … Continue reading "LASER"
Core MemoryCore memory enhanced the productivity of early computer operators. Not only does core memory store information but also does not need power to maintain memory. Wang & Woo created computer memory that would sit on tiny magnetic rings, strung together into cores. These were smaller than vacuum tubes and used less power. Furthermore, they did … Continue reading "Core Memory"
Shareholder Value Theory: Milton Friedman ReduxOn September 13, 1970, Milton Friedman published one of the most arguably economically destructive articles in history, “The Social Responsibility Of Business Is to Increase Its Profits,” in the New York Times. The article is available, in PDF form, for subscribers from the New York Times website. Friedman advanced the idea that managers are agents … Continue reading "Shareholder Value Theory: Milton Friedman Redux"
Fast FoodMcDonald’s primary innovation is that food should be ready instantly. No sooner does a customer order than food appears. Individual restaurant orders, individually prepared was the norm for non-buffet restaurants before McDonald’s. In 1937, the McDonald brothers created their iconic restaurant and built several stores. Eventually, Ray Kroc was a 52-year-old milkshake machine salesman who … Continue reading "Fast Food"
LinuxLinux is a stable and secure operating system. The operating system is open-source and free. However, there are many companies that sell support for Linux, and maintenance is typically the source for most of the cost comes of maintaining an operating system. Background Limited to 16 concurrent users at his school’s computer, Linus wanted a … Continue reading "Linux"
DynamiteDynamite blows up otherwise difficult to move things, like boulders, mountains, and bedrock. It lowers the cost of removing rocks to make level land and tunnels, railroads, roads, and enables foundations for skyscrapers. In 1847 chemists Théophile-Jules Pelouze and Ascanio Sobrero had synthesized nitroglycerin but the chemical was unstable and difficult to harness. Nobel encased … Continue reading "Dynamite"
Electric MotorMore inspirational to future innovators than practical, the Faraday motor shows that electricity can do the same function as a steam engine, but without the smoke. Faraday’s DC motors, like modern DC motors, had limited functionality. But his innovation served as the first step towards electrification. Faraday has three major innovations, the electrical motor, generator … Continue reading "Electric Motor"
Time-Sharing/Multitasking ComputerEarly Computers Early computers stored programs and data on punch cards. Most cards contained 80-characters, which is why early terminal programs were typically 80-characters per line. Punch cards are exactly what they sound like, physical cards. Each card is one line of a computer program or one piece of data. As users typed, a machine … Continue reading "Time-Sharing/Multitasking Computer"
StatinsStatins dramatically lower blood cholesterol, and the likelihood of heart attacks. Akira Endo discovered statins. Akira Endo & His Molds Endo is a Japanese researcher with a lifelong fascination related to fungi. Recalling that Fleming accidentally discovered penicillin, he theorized that fungi might hold other miracle drugs. Endo noted that Americans are much heavier than … Continue reading "Statins"
Precision Guided Munitions“In the past, wars’ slaughter has been largely confined to armed combatants. Obviously the airman, riding so high above the earth that cities look like ant hills, cannot aim his deadly cargo at armed males. All below will be his impartial target.” Major Gen. James Fechet, US Army Air Corps, 1933 Precision Guided Munitions (PGM’s) … Continue reading "Precision Guided Munitions"
InsulinInsulin keeps diabetics alive. Banting and Best discovered insulin, winning them the Nobel Prize. Banting stole most of the credit, but historians argue they co-discovered insulin together. They won the Nobel Prize together. Banting despised Best and the two never spoke again. To continue his work, Banting received a lifetime annuity by the Canadian government. … Continue reading "Insulin"
Chlorofluorocarbons “Freon”Freon is the brand name of a Chlorofluorocarbon gas. It replaced other refrigerant chemicals that were more toxic or volatile, including ammonia. Throughout the 20th century, Freon became the dominant refrigerant gas. The team that invented Freon was led by Thomas Midgley, Jr., who earlier had invented leaded gasoline. It was a joint venture between … Continue reading "Chlorofluorocarbons “Freon”"
Transistor RadioDeveloped in 1947 but commercialized in 1954, transistor radios are small. Battery-operated portable radios that fit in a pocket. They rely on transistors rather than vacuum tubes. There were several attempts to build radios with transistors but none were optimal until 1954. Eventually, a Texas Instruments team invented the Regency TR-1, the first radio miniaturized … Continue reading "Transistor Radio"
Braille Writing1829 Louis BrailleCharles Barbier Most of the innovations on Innowiki are for-profit inventions. While it could be argued that Braille’s writing technique opened new markets, the size of that market was limited to blind people. However, the impact of the innovation — a process enabling the disabled to regain one of the most important human … Continue reading "Braille Writing"
Interchangeable Standardized Parts: the “American Manufacturing Method”Standardized parts allow parts of a machine to be swapped out, enabling factories to manufacture parts without worrying about the larger machine. Interchangeable parts vastly lowered manufacturing costs. Check out the video we created about interchangeable standardized parts: Today, everything from cars to computers, software and even food, is interchangeable. We’re annoyed that a USB … Continue reading "Interchangeable Standardized Parts: the “American Manufacturing Method”"
