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"
NylonNylon is a popular low-cost high-strength silk alternative. It vastly lowered the cost of producing silk-like fabric. Carothers started undergraduate school, at Tarkio College in Missouri, as an English major but switched to chemistry due to an influential professor. He excelled, working as an instructor during his undergraduate years. He went on to earn a … Continue reading "Nylon"
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"
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"
Paid Cable Television ChannelsBackground Charles Dolan was a cable TV pioneer who received a license to build a cable television system in lower Manhattan. Due to New York City restrictions, cables needed to run underground, vastly increasing the cost of the infrastructure. New Yorkers lacked enthusiasm. By 1971, Dolan only had 400 subscribers. To increase sales, Dolan eventually … Continue reading "Paid Cable Television Channels"
Optical Disk (CD/DVD)“If it was any good, IBM would have already invented it.” James Russell CD’s and DVD’s increase convenience from analog tapes for music and video. Users may instantly jump to songs or parts of a video. Unlike tapes, CD’s and DVD’s never wear out reducing replacement media cost. David Paul Gregg In 1961, Gregg claims … Continue reading "Optical Disk (CD/DVD)"
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"
Computer GameBackground Early computers used punch cards to load programs and data into computers. The software was a stack of cards, each card one line of a program. Data input were cards on the top of the stack. Eventually, then the entire thing fed into a card reader. The reader read the stack, processed the data, … Continue reading "Computer Game"
Transatlantic CablesTransatlantic cables shrunk the world, vastly increasing the speed and lowering the cost of intercontinental communications. The first cable functioned only a few weeks. Transmissions, in Morse Code, were especially slow. Field, as a young businessman, joined a paper company that failed six months later. Despite his status as a young employee, with no responsibility … Continue reading "Transatlantic Cables"
Reasonably Priced Business Computer (IBM/360)The IBM/360 is the first mass computer, designed as a general-purpose computer affordable for mid-sized businesses yet powerful enough for large enterprises. Background In 1962, IBM’s revenue was $2.5 billion. CEO Thomas Watson Jr. believed in the vision of a general-purpose computer that supports timesharing, the ability of a computer to do multiple things at … Continue reading "Reasonably Priced Business Computer (IBM/360)"
Mobile PhoneMobile phones allow calls from anywhere that’s within range of a tower. They vastly increase productivity, convenience, lower the risk of a missed call, and they’re fun. Mobile phones work by beaming voice (and, later, data) to a tower, seamlessly switching from tower-to-tower as the person moves. Cooper Creates the Mobile Phone Battery-operated gadget maker … Continue reading "Mobile Phone"
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"
Air ConditioningCombining prior innovations and ideas, Carrier added his own ー related to humidity ー and created modern air conditioning. Tasked with controlling the humidity in a printing plant, because humidity affects paper, he found the connection between humidity and temperature. Carrier designed equipment to control humidity that also controlled temperature, modern air conditioning. By 1911, … Continue reading "Air Conditioning"
RailroadRailroads vastly lowered the cost of moving people and goods over land. Richard Trevithick invented the locomotive engine. However, he never quite created a fully functioning railroad: Trevithick’s locomotive was a literal circus act, pulling children around a track at a circus. His core innovation was the idea of a high-pressure steam engine. Prior steam … Continue reading "Railroad"
Object-Oriented ProgrammingObject oriented programming is the first of countless Xerox PARC inventions. Vastly simplifying, there are two ways to program a computer. In procedural programming, each thing the computer does is listed. Conditional statements tell the computer which path to follow. Comparatively, in object-oriented programming, objects mimic real life. Programmers then act on these objects. For … Continue reading "Object-Oriented Programming"
