Condensing Steam EngineThe Watt condensing steam engine is widely viewed as the primary machine responsible for the Industrial Revolution. It enabled the use of engines anywhere, not only next to coal mines. Whereas factories before the Watt engines needed to be near high-volume streams, to derive power for water wheels, the Watt engine operated at a low … Continue reading "Condensing Steam Engine"
Personal Portable Music PlayerBattery operated portable personal music players are fun, enabling users to build a cocoon of their own music. Portable radios and stereos date back to the invention of the transistor. Over time, these grew in size and power. Enormous stereos run from batteries, “boom boxes,” were commonplace. However, boom boxes played music from speakers and … Continue reading "Personal Portable Music Player"
Slide RuleSlide rules are the original mechanical calculators. They could quickly multiply and divide large numbers. Slide rules are based on logarithms. These are tables of the number another number is raised to produce a third number. Scales of roots do the opposite. John Napier realized sets of log scales placed next to one another easily … Continue reading "Slide Rule"
Modern Computing v1: The Mother of All Demos.On December 9, 1968, the modern world was born. Background Douglas Engelbart, working for the Stanford Research Institute (SRI) showed the future of modern computing to a roomful of people that, for the most part, understood virtually none of it. In a tour de force, Engelbart introduced the world to video conferencing, teleconferencing, hypertext, word … Continue reading "Modern Computing v1: The Mother of All Demos."
VideoconferencingVideoconferencing is well over 50 years old. Today, it is fast and virtually free over the Internet. However, aside from extremely formal or informal events, videoconferencing has largely failed to catch on. Background AT&T introduced videoconference at the 1964 World’s Fair. People in New York waited in line to walk into a booth and spend … Continue reading "Videoconferencing"
MicrocomputerThe first microcomputer, the Altair 8800, was like a French bulldog. That is, it was ugly, expensive, and not all that bright, but people loved it. The Altair didn’t even have a display, just LED’s that lit up. Most significantly, it served as the inspiration for a small number of future computer entrepreneurs. The cover … Continue reading "Microcomputer"
Fast FoodMcDonald’s primary innovation is that food should be ready instantly. No sooner does a customer order than food appears. Individual restaurant orders, individually prepared was the norm for non-buffet restaurants before McDonald’s. In 1937, the McDonald brothers created their iconic restaurant and built several stores. Eventually, Ray Kroc was a 52-year-old milkshake machine salesman who … Continue reading "Fast Food"
Velox Photo PaperBaekeland, a chemistry student, worked on an improved photographic paper. Before his invention, photo papers required bright sunlight for exposure. This constraint limited photo developing to daylight hours on sunny days and made photo print results unpredictable. Baekeland created a high contrast reliable photo paper. His paper was sensitive enough to work with gas lighting, … Continue reading "Velox Photo Paper"
Laser PrinterLaser printing is the only Xerox research project to generate significant revenue and profit for the company. However, it predates PARC. Subsequently, most Xerox laser printing revenue came from licensing the technology to other firms. Despite their success in the enterprise market and strong brand Xerox never built a widely used Xerox-brand laser printer. Background … Continue reading "Laser Printer"
Branch BankingBranch banking allows ordinary people to utilize banks and theoretically makes banks safer since larger banks are less prone to catastrophic losses than smaller banks. Amadeo Pietro “A.P.” Giannini started life as a fruit wholesaler. He built and sold a large business, decided he was too young to retire, then innovated an entirely new type … Continue reading "Branch Banking"
Weather ForecastThe development of the telegraph in 1835 made weather forecasting possible. Before that time, people used various methods to guess changes in the weather. Some observations were accurate. For example, the correlation of barometric pressure to weather changes. However, there was not enough geographically widespread data to methodically forecast weather. The Britsh government charged Francis … Continue reading "Weather Forecast"
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"
Turing Complete Electronic Computer, ENIACBackground Commissioned in 1943, partially functional in July 1944, but not entirely finished until Feb. 1, 1946, ENIAC is the first all-electronic general-purpose Turning complete computer. Engineers built ENIAC to calculate ordinance tables. Eventually, von Neumann used the computer to perform calculations for nuclear weapons and break ENIGMA encrypted messages. Built at the University of … Continue reading "Turing Complete Electronic Computer, ENIAC"
Steam TurbineIn much the same way that Watt’s condensing steam engine vastly increased the value of Newcomen’s engine, the steam turbine vastly improved the value of Edison’s electric factory. Steam turbines allow steam, generated by heating water, to efficiently turn generators, usually to make electricity. In addition to steam, water (ex: waterfalls) or wind (ex: windmills) … Continue reading "Steam Turbine"
Rotary Printing Press (Web Offset)Rotary web printing presses revolutionized newspaper publishing. The technology enabled larger, faster newspaper printing at a far lower cost. However, digital distribution of news via the world wide web has dramatically decreased demand for paper newspapers. Hoe’s web press printed in a continuous sheet, a roll, then machines cut the paper into sheets. When connected … Continue reading "Rotary Printing Press (Web Offset)"
