Contact LensesLeonardo DaVinci proposed the first contact lens idea in his Codex of the Eye, published in 1508. His invention involved putting a fishbowl over one’s head filled with water to refract light. This is arguably not his finest work though, in hindsight, he was onto something. René Descartes picked up DaVinci’s work in 1636, proposing … Continue reading "Contact Lenses"
Electrical Transformer1831 Michael Faraday Faraday’s transformer acted as a knowledge bridge to future innovators that electricity could be transformed. It wasn’t especially useful on its own except to signal to future scientists what is possible. His transformer was vital to the creation of the modern electricity grid and electrical innovations. The device itself is hand-built by … Continue reading "Electrical Transformer"
Carbon Fiber1958 Roger Bacon Paper airplanes glued together are fun but not something anybody would actually fly on. But that is essentially what modern jet aircraft are. Carbon fiber is essentially threads glued together into a fabric and turned into the bodies of aircraft, the wings, cars, bicycles, and countless other objects. Carbon Fiber is stronger … Continue reading "Carbon Fiber"
MinicomputerComputers were big. They were enormously expensive and physically giant machines. IBM’s nickname from this time was Big Blue on account of the size of the company and their computers. History Olsen developed, by current standards, small transistor-based computers at MIT. He left in ’57 to form a company, the Digital Computer Corporation. It was … Continue reading "Minicomputer"
Computer Numerical Control (CNC) MachineComputer Numerical Control (CNC) machines create identical interchangeable parts. They simplify manufacturing and reduce the risk of human error producing parts. Starting in 1949, John Parsons worked with Frank Stulen at Gordon S. Brown’s Servomechanisms Laboratory at MIT to develop a system where punch cards controlled a machining tool, called Numerical Control (NC). This evolved … Continue reading "Computer Numerical Control (CNC) Machine"
Stainless Steel1913 Harry BrearleyW.H. Hatfield Stainless steel is strong and has high heat resistance, just like ordinary steel. It resists corrosion, it’s formable and weldable and, unlike regular steel, does not rust. It lowered the cost of everyday items. For example, rather than silver, tableware could be made from stainless steel. Stainless steel also lowered the … Continue reading "Stainless Steel"
MimeographMimeographs are essentially low-cost but low-quality and easy-to-use printing presses. They produced good-enough copies at a cost far lower than hand copying. Copies are produced from user-created stencils. Mimeographs remained the dominant form of document duplication for almost a century until photocopy machines became inexpensive and ubiquitous. For decades, mimeographs were the only way to … Continue reading "Mimeograph"
Nuclear SubmarineNuclear submarines can stay underwater for an unlimited amount of time, or at least until the food runs out. Prior to nuclear subs, there were diesel-electric subs, that still exist today. However, these subs use diesel engines to recharge batteries. Therefore, diesel subs must surface to turn on the diesel engines and recharge their batteries, … Continue reading "Nuclear Submarine"
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"
Niche MarketingWalker, daughter of freed slaves, is the first self-made millionaire woman and the first self-made millionaire African American (maybe – tax returns suggest it was $600K but she did very well for herself). She invented beauty products for Black people. Walker was born in a sharecropper’s cabin. She is orphaned at seven. A freelance launderer, … Continue reading "Niche Marketing"
Archie McCardell: Worst CEO EverArchie McCardell is the worst CEO in history. Sure, there are CEO’s who committed crimes, CEO’s who bankrupt their businesses, and CEO’s who looted their businesses. There are crooks, those who hire cronies, people who paid bribes, plenty who demanded sex or servitude, and countless sociopaths. In fairness to him, Archie did none of these … Continue reading "Archie McCardell: Worst CEO Ever"
Water Frame Spinner / Modern FactoryRichard Arkwright’s Water Frame Spinner created factories that did not require highly skilled labor. Women and children, with no training, worked in factories that churned out low-cost good enough quality fabric at high volumes. This vastly lowered the cost of fabric. Arkwright was from a poor family: his father was a tailor. He improved on … Continue reading "Water Frame Spinner / Modern Factory"
ChemotherapyChemotherapy refers to a group of drugs that fight cancer. Surgery and radiation were the two common anti-cancer therapies before the discovery of effective chemotherapy. Immunotherapy was also studied but showed little promise. Background In the 1800s, scientists thought drugs might be able to fight cancer. However, none of them worked well. In the 1910s, … Continue reading "Chemotherapy"
Viagra (Sildenafil)It’s hard to write seriously about Viagra. No sooner did the drug help erectile dysfunction than it opened the opportunity for countless puns. Additionally, the name of co-inventor Albert Wood worsens the situation. However, in hindsight, Viagra cured a serious problem. Background Wood and Viagra co-inventor Peter Dunn were working on a blood pressure medicine. … Continue reading "Viagra (Sildenafil)"
Health InsuranceBackground Germany has the oldest health insurance system, the Sickness Insurance Law of 1883. Employers paid one-third and employees two-thirds. The insurance covered both medical treatment and sick leave. In 1911, the UK created basic health insurance. Russia followed in 1912, nationalizing all healthcare after the Russian Revolution of 1917. Most countries rolled out some … Continue reading "Health Insurance"
