Adding MachineBlaise Pascal was a French mathematician who lived in the 1600s. He is most known for his work in geometry and statistics but is included here for building the first non-abacus adding machine. Going back briefly, the abacus dates back to at least 300BC. Our earliest cutoff date for innovations is the printing press or … Continue reading "Adding Machine"
Voice Over IP (VOIP)Voice Over IP (VOIP) transmits voice calls over the internet, allowing people to speak to one another. Invented in 1995, VOIP came about after countless seemingly more complex inventions including web-based video. Interestingly, the likely reason for the late invention date is incentives. Businesses believed that the internet would work well for broadcasting, displacing other … Continue reading "Voice Over IP (VOIP)"

Condensing Steam EngineThe Watt condensing steam engine is widely viewed as the primary machine responsible for the Industrial Revolution. It enabled the use of engines anywhere, not only next to coal mines. Whereas factories before the Watt engines needed to be near high-volume streams, to derive power for water wheels, the Watt engine operated at a low … Continue reading "Condensing Steam Engine"
C Programming LanguageDennis Ritchie went on to create multiple aspects of modern computing culture. Indeed, odd hours, obsessed screen time, sloppy dress, funky naming conventions, and – most importantly – those attributed tied to brilliant and useful code all belong to Ritchie. Sometime between Ritchie, the software engineer straight enough to gain employment at Bell Labs, and … Continue reading "C Programming Language"
Long Lasting Light BulbEdison’s bulb is well-known but what’s less understood is the enormous infrastructure required to power it. Edison created a power plant in New York City, power cables, transformers, power meters, insulators. When the lights finally came on, at the New York Times building, it represented the end of a herculean undertaking and the beginning of … Continue reading "Long Lasting Light Bulb"
Discount AirlineAs the airline market developed, the US found it necessary to regulate interstate air transport as a “public utility.” Significantly, the “Civil Aeronautics Board” (CAB) regulated fares, routes, and schedules. The benefit of regulation was predictability and widespread routes. For example, a carrier that wanted to fly from New York to Chicago might be required … Continue reading "Discount Airline"
Combine HarvesterBackground Before the combine harvester farmers would need to hire groups of people to harvest crops before they rotted. Since there were only so many people available, the ability to harvest limited the volume of crops that could be grown. The harvester fixed that, doing the work of many people at once. This enabled the … Continue reading "Combine Harvester"
Portable ComputerPortable computers are more convenient than stationary computers. They increase productivity for people who travel, allow office workers to bring work home, and enable telecommuting. Background Portable computers were developed at (where else), Xerox PARC. The Xerox NoteTaker, released in 1978, was the first portable computer. Staying true to Xerox tradition, only about ten were … Continue reading "Portable Computer"
Credit CardMerchants have always issued credit in one form or another directly to customers. But the idea that a bank would issue credit to purchase anything then, eventually, collect from their customer is newer. In 1946, after WWII, John C. Biggins invented the first universal credit card, called “Charg-It.” However, the card only worked at participating … Continue reading "Credit Card"
Circular Saw1813 Tabitha Babbit In 1777, Samuel Miller patented the first circular saw. However, the wind-powered saw did not have enough power to be of practical use. In 1813, Tabitha Babbit, a Shaker, invented the circular. Her insight was that sawing back and forth wasted half the motion of a saw. In response, she created a … Continue reading "Circular Saw"
Lithium-Ion BatteryLithium-Ion Batteries (LIBs) power everything from smartphones to power tools and electric cars. Entire cities store power generated during the day, via solar panels, for use at night from large lithium battery arrays. One of the largest factories in the world, the Tesla Gigafactory, is devoted solely to manufacturing Lithium-Ion batteries. Background An ability to … Continue reading "Lithium-Ion Battery"
Planned Communities / Cookie-Cutter SuburbsLevitt produced inexpensive homes. He subcontracted building parts of the home to specialists who would do the same work repeatedly, from house to house. His methods reduced costs and increased quality: a standardized parts assembly line for houses. Levitt’s methods were copied with cookie-cutter style suburbs dotting the US especially, where people have limited choices … Continue reading "Planned Communities / Cookie-Cutter Suburbs"
Nuclear WeaponsCaltech professor Robert Oppenheimer lead a team of researchers at Los Alamos to invent the atomic bomb. Along with some of the most noteworthy physicists in the world, he oversaw the development of the nuclear bomb. The Manhattan Project, like the code-breaking at Bletchley Park, was intensely secretive. Los Alamos, in New Mexico, was built … Continue reading "Nuclear Weapons"
Color Photography1908 James MaxwellSergey Prokudin-Gorsky Scottish physicist James Maxwell laid the groundwork for color photography. Eventually, Russian Sergey Prokudin-Gorsky perfected the technique using three exposures through a red, green, and blue filter. Recombining each exposure into one print accurately portrays color. This method, combining red, green, and blue, remains the foundation of how color is reproduced … Continue reading "Color Photography"
