EmailRay Tomlinson would likely have lived in anonymity but for Shiva Ayyadurai, the man who claimed to invent email as a 14-year-old child. Ayyadurai is certainly bright, a Fulbright scholar who holds four degrees from MIT. He ran against Sen. Elizabeth Warren in the 2018 Senate race, attracting 91,710 votes. Ayyadurai’s claim as the inventor … Continue reading "Email"
Inexpensive Postage & StampPenny postage refers to low-cost prepaid postage. Background By the early 1800s, postage was centuries old. But many postal carriers were essentially government couriers. They were extremely expensive. However, recipients could reject mail by refusing to pay. This made the entire system unpredictable and unstable. Furthermore, postal employees sometimes opened and read mail. Government censors … Continue reading "Inexpensive Postage & Stamp"
Color MoviesThough not the first color movie, The Wizard of Oz left an indelible mark. Swapping from the old world of black and white to color the world flew over the rainbow. Movies have never been the same since. Kalmus, an MIT alum, created a process for color movies and ramped up a company, Technicolor. Initially, … Continue reading "Color Movies"
Communication Satellite“This satellite must be high enough to carry messages from both sides of the world, which is, of course, an essential requirement for peace…” President Kennedy, July 23, 1962 Communication satellites bring the world closer together, with instant communication. They are especially important for communication, beaming information from one central place to many more. For … Continue reading "Communication Satellite"
Highway (Limited Access Road)High-speed streets with minimal interruptions were a novel concept when first created. Highways, technically called limited access roads, have entry and exit ramps are few and located far between. Long Island, near New York, was home to the first highway in 1911. Americans continued to build highways, enacting the Federal Highway Act of 1921. Germans … Continue reading "Highway (Limited Access Road)"
Electricity Factory & Distribution NetworkAfter inventing the long-lasting light bulb, Edison needed an electrical grid to deploy his innovation. Remember that, at this time, all electrically powered devices ran off batteries. Background The Edison Electric Illuminating Company, founded after the light bulb company, funded both an electrical generation station, grid, and all supporting equipment. Edison innovated better dynamos, circuits, … Continue reading "Electricity Factory & Distribution Network"
AirplaneWilbur and Orville Wright invented the airplane with their first flight in 1903. Urban myth describes an easy story where the bicycle mechanic brothers built an airplane from spare parts. In reality, the innovation was a long, slow, methodical, and extremely dangerous project. Background People had been building various forms of fixed-wing gliders for years. … Continue reading "Airplane"
Hydraulic PressBefore the press, shaping metal was a slow, difficult, expensive, and laborious process. The hydraulic press allows metal to be easily and inexpensively shaped. Today, the same hydraulics power a lot of modern industrial equipment. Bramah, a farmer’s son, was an innovator who specialized in locks. He created and patented many types of locks. He … Continue reading "Hydraulic Press"
Hybrid CornGenetic modification by people have produced virtually all plants and animals in the western world. Broccoli, cauliflower, cabbage, kale, kohlrabi, and brussels sprouts are all derived from a wild mustard plant in Europe. None of these vegetables exist but-for early genetic engineering. Similarly, all dogs, cows, pigs, sheep, and chickens are modern man-made creations. Scientists … Continue reading "Hybrid Corn"
Central BanksBackground The first central bank was Swedish Riksbank. The Swedish government chartered it to act as a clearinghouse for commerce. In 1694, the Bank of England was founded. It’s primary purpose was to purchase government debt. Napoleon chartered the Banque de France to stabilize currency after the French Revolution. Early central banks, and their modern … Continue reading "Central Banks"
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"
Locomotive (High-Pressure Steam Engine)The high-pressure steam engine was invented about the same time by Richard Trevithick in the UK and Oliver Evans in the US. Neither man knew about the other. Richard Trevithick Trevithick, a mining engineer, built a high-pressure steam-powered car, the “Puffing Devil,” in 1801, taking it for a ride around town, picking up friends. He … Continue reading "Locomotive (High-Pressure Steam Engine)"
Programmable Logic Controller (PLC)Programmable Logic Controller’s (PLC’s) are small single-purpose computers. They control machines and are common in cars. You probably own more PLC’s than any other type of computer. Today, a single-car has a myriad of PLC’s, usually networked together. PLC’s replace hard-coded wiring, automating tasks. PLC’s often read input from analog sensors. Responding to temperature, sensing … Continue reading "Programmable Logic Controller (PLC)"
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"
Wire RopeWire rope is far stronger than natural-fiber rope. German mining engineer Wilhelm Albert invented wire rope about 1834. Wire rope is sometimes called Albert rope after the inventor. Early on, they were used to hoist stuff to and from silver mines in the Hartz Mountain. The first rope was three wrought-iron cables twisted around one … Continue reading "Wire Rope"
