HelicopterIgor Sikorsky was a Russian aircraft designer. He created various aircraft for the Russian army, including early helicopters. No sooner did the Bolshevick’s take over than Sikorsky fled to the US after the Russian Revolution in 1919. In the US, he created a business, Sikorsky Aircraft Corporation, designing aircraft. His first American airplane was a … Continue reading "Helicopter"
Long Playing (LP) Records & Talking MoviesLong-playing records play for a long time, enabling records with more than one song. Background As Edison’s phonograph evolved, the recordings eventually migrated to small disks played at 78 rotations per minute (rpm). Each disk held about three minutes of music per side. Filmmakers wanted to add sound to their movies. Before then, movies ran … Continue reading "Long Playing (LP) Records & Talking Movies"
Electron MicroscopeElectron microscopes enable scientists to see extremely small particles. In the 1920s, scientists discovered that electrons in a vacuum behave much like light except they can be manipulated with electric and magnetic fields. Since electrons curve around particles, these electron microscopes are vastly more powerful than traditional light-based microscopes. Ruska invented the electron microscope at … Continue reading "Electron Microscope"
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"
24-Hour NewsBroadcast news was a staid affair, a half-hour visual summary showing events of the day. American networks NBC, ABC, and CBS each had a newscast and each aired at the same time. Ted Turner inherited an outdoor advertising company. To build more advertising outlets he purchased a third-rate television station running old TV series and … Continue reading "24-Hour News"
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"
Fiber Optic CableFiber optic cable is extremely thin cable that uses light, rather than electricity, to send information. Background In 1854, John Tyndall demonstrated that light bends through water. In 1880, Bell showed an analog voice signal propelled by light. He called it a Photophone. However, the process was subject to interference and abandoned. Additionally, Europeans demonstrated … Continue reading "Fiber Optic Cable"
Nuclear Aircraft CarrierNuclear aircraft carriers are enormous ships capable of traveling the world indefinitely. Indeed, the ships feature relatively large flight-decks capable of launching and landing fixed-wing aircraft, typically fighters. At 1,123 ft. (342 m.) the USS Enterprise is an enormous ship. In contrast, only oil supertankers are larger. The Enterprise supported 4,600 service members. First launched … Continue reading "Nuclear Aircraft Carrier"
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"
Relational Database Management System (RDBMS)Relational databases simplify the storage and retrieval of related information. For example, rather than storing the state a person lives in a relational database might store a number to a single list of all states. Significantly, this reduces overall storage needs and makes indexing and searching significantly easier and subsequently faster. Edgar Codd, working at … Continue reading "Relational Database Management System (RDBMS)"
PsychoanalysisPsychoanalysis is a process of working with highly trained professionals. Through discussions, doctors uncover and heal often forgotten events or disturbances. Freud was a neurologist who noticed that patients under hypnosis talked about disturbing events, oftentimes from their childhood. He theorized that speaking about these events would allow a person to confront, heal, and work … Continue reading "Psychoanalysis"
Organic Light-Emitting Diode (OLED)Organic Light-Emitting Diodes (OLEDs) emit light with virtually no electricity. Lamps, televisions, mobile phone, and computer monitors are common applications. Additionally, OLEDs are bright, high-contrast, and extremely thin. OLED screens are faster, brighter, and use far less energy than LED-based displays. As the technology develops, they will eventually cost less than LED displays. OLED’s are … Continue reading "Organic Light-Emitting Diode (OLED)"
Rock & Roll“If you’re not doing something different, you’re not doing anything.” Sam Phillips Background Billboard magazine started charting songs in 1940. Eventually, they divided songs into three categories, pop, country-and-western, and “race music.” Around 1949, race music was renamed rhythm and blues (R&B). Music sales were proprietary and closely guarded so Billboard based their charts off … Continue reading "Rock & Roll"
Portable VentilatorVentilators breathe for people when they cannot breathe on their own. John Emerson was a physician focused on breathing devices who developed the first mass produced iron lung. Building on Emerson’s work, Bird developed the portable ventilator and, later, created a company, Bird Corp., to commercialize it. Bird Corp. created a home ventilator in 1965, … Continue reading "Portable Ventilator"
