Electrical Generator (Dynamo)1831 Michael FaradayJoseph Henry No one person “discovered” electricity. The story about Ben Franklin flying a kite with a key in a thunderstorm and discovering electricity when the kite was struck by lightning is especially ridiculous. A Russian apparently tried the same experiment soon after reading about it and was electrocuted. Alessandro Volta, who invented … Continue reading "Electrical Generator (Dynamo)"
AutomobileIt’s difficult, and arguably pointless, to separate the innovation of the automobile and Internal Combustion Engine (ICE). The use of an ICE for a “horseless carriage” was so obvious that early engines were all used for cars. Engine propelled buggies were, by far, the most popular use case though ICE’s also powered other applications. Early … Continue reading "Automobile"
Microcomputer Operating System (CP/M)Operating systems tie the parts of a computer together, transforming it from silicon into something we can interact and use. Gary Kildall In 1973, Gary Kildall wrote the first widely used microcomputer operating system, CP/M. It gained popularity over the years. Kildall had a Ph.D. in computer science of Univ. WI. He created a simulator … Continue reading "Microcomputer Operating System (CP/M)"
Cathode-ray Tube (CRT)Cathode ray tubes are a vacuum tube with an electron gun at the back. The gun shoots electrons through the vacuum onto a screen which creates images. Thick screens that predate flat-screen televisions and computer monitors are cathode ray technology. Background German scientists Julius Plücker and Johan Hittorf discovered cathode-ray tubes. Hittorf noticed a negative … Continue reading "Cathode-ray Tube (CRT)"
TelegraphBackground Samuel Morse invented the telegraph. He learned that his wife was sick while working in a different city. By the time he arrived home, she had died. Morse determined to invent a faster message delivery system. Like Fulton, Morse was an artist before going into business. He had no background in science or engineering. … Continue reading "Telegraph"
Wi-FiIn 1941, Hollywood actress Hedy Lamarr devised a system and submitted a patent for radio signals that changed frequencies. Background Hedwig Eva Maria Kiesler (Heidi Lamar) was born in Vienna. She is most famous as the first woman to appear nude in a mainstream film. In the same movie, she was also the first woman … Continue reading "Wi-Fi"
Sound Over RadioAfter a series of other innovations involving radio, Fessenden invented sound over radio in 1906. Before then radio typically carried Morse Code signals. He created a company, NESCO, that struggled with IP, financing, and people issues. The owners, including Fessenden, hoped to sell the company to AT&T or GE but that deal did not close. … Continue reading "Sound Over Radio"
Washing MachineBefore washing machines, wealthier families hired maids or brought their laundry to cleaners. Most people did laundry by hand, a time-consuming process usually tasked to women. Washing machines dramatically lowered the cost of washing clothes while increasing cleanliness. A patent issued to Fisher on Aug. 9, 1910, for an electric washing machine. Many people claim … Continue reading "Washing Machine"
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"
Clusters of Regularly Interspaced Short Palindromic Repeats (CRISPR)CRISPR is like a word processor for DNA. It allows easy and inexpensive gene editing. Edited genes are passed to future generations, making mutations permanent. Doudna and Charpentier Doudna and Charpentier worked on and invented the technology as a team. First, they worked on plants and, later, on animals. History becomes murkier with the involvement … Continue reading "Clusters of Regularly Interspaced Short Palindromic Repeats (CRISPR)"
- Blue Ocean Strategy Basics – Buyer Experience Cycle
Put yourself in the shoes of your buyer The Buyer Experience Cycle (BEC) is a superficially short and often overlooked blue ocean exercise. In the books, tutorials, and even the tool itself, the BEC is always coupled with the Buyer Utility Map though they’re separate parts of the exercise. In short, the BEC is a … Continue reading "Blue Ocean Strategy Basics – Buyer Experience Cycle"
Machine GunMaxim is a colorful character who claims to have invented everything from the asthma inhaler to automated fire sprinklers and even the lightbulb, despite Edison’s well documented account. He also experimented with helicopters, airplanes, and amusement park rides. While on vacation in Vienna he claims another American told him “If you want to make a … Continue reading "Machine Gun"
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"
Global Positioning System (GPS)GPS uses satellites to compute positioning in 3D space, allowing automatic mapping and advanced navigation. The Soviet Union launched the Sputnik satellite on October 4, 1957. Sputnik did nothing but send out radio pings audible on radio receivers on earth. Conveniently, they launched the satellite to fly over then arch-enemy the United States. As scientists … Continue reading "Global Positioning System (GPS)"
Microwave OvenPercy Spencer is a self-taught engineer who did not finish even primary school. He self-taught himself math, science, and electrical engineering while standing guard on ships in the Navy. Before, during, and after WWII, Spencer worked on top-secret magnetrons, the high-powered electrical devices at the heart of a RADAR system. One day he noticed that … Continue reading "Microwave Oven"
