Binary TheoryIn 1935 theoretical mathematician Alan Turing proposed a machine that would use a series of on and off switches that could represent or compute anything. Turing joined the war effort to build mechanical computers that decrypted Enigma messages. Eventually, he helped with electronic computers. His theories underpin all modern computers. Subsequently, Turing envisaged reasonably sentient … Continue reading "Binary Theory"
Industrial RobotThough understated at the time, few inventions have had as much impact as the industrial robot. Industrial robots were invented by George Devol. A prolific innovator, Devol patented the “Unimate” – a term he coined – in 1954 to name his robot. Robots have existed in science fiction for ages, often as machines in human … Continue reading "Industrial Robot"
AsphaltAsphalt increased the utility or roads by allowing horses to travel faster, carriages and bicycles ride more smoothly, and (later) enabled cars. Natural asphalt paved the Champs-Élysées in 1824. However, it was unstable and difficult to maintain. de Smedt created an artificial asphalt, manufactured from oil, that was more consistent and manageable than natural asphalt. … Continue reading "Asphalt"
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"
Instant MessagingSending instant messages by computer is fun and convenient. Moreover, text chatting is asynchronous, unlike voice or video. Accordingly, people need not communicate in real-time. Surprisingly, text messaging became extremely popular. The earliest instant messaging system designed for that purpose was “Talkomatic” and “term-talk” for the PLATO system. College students David Wooley and Doug Brown … Continue reading "Instant Messaging"
Tetraethyllead (Leaded Gasoline)Leaded gasoline prevented engine ping, making driving safer and more pleasant. Correspondingly, it also caused an enormous amount of extremely toxic pollution. Working for GM under the direct supervision of Charles Kettering at Dayton Research Laboratory, Midgley discovered the benefits of adding lead to gasoline. They named their innovation Tetraethyllead, avoiding any mention of lead, … Continue reading "Tetraethyllead (Leaded Gasoline)"
Gregorian Calendar“It is pleasant for an old man to be able to go to bed on September 2, and not have to get up until September 14,” wrote Benjamin Franklin in 1752. The reason for the shift was the adoption of the Gregorian calendar, devised in 1582. Background Roman Julius Caesar invented the modern calendar. Before … Continue reading "Gregorian Calendar"
- Blue Ocean Strategy Basics – Breaking the Value/Cost Trade-Off
Oftentimes spending more doesn’t get more and, sometimes, gets less Michael Porter is the father of modern business strategy theory and defined a few basic ideas. Core among them is that business centers around competition. Competitors, new market entrants, suppliers, customers, and substitute products are five forces that influence profitability, he argued in his famous … Continue reading "Blue Ocean Strategy Basics – Breaking the Value/Cost Trade-Off"
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"
Social NetworkWhen they’re not rigging elections, sowing discord, or amplifying hate social networks are a fun, simple, and convenient way to stay in touch. However, they suffer serious privacy issues under current implementations. Electronic social networks, in various forms, are older than Facebook co-founder Mark Zuckerberg. The first online bulletin-board enabling people to chat and hang … Continue reading "Social Network"
SecuritizationSecuritization enables income streams of pooled loans, reducing overall risk to lenders. This spreads the risk of both prepayments and defaults, lowering the cost of credit. Background Denmark created pooled mortgages, called covered bonds, in 1850. Switzerland followed in 1930. In 1970 US government pseudo-agency Ginnie Mae (GNMA) created the first securitized pool of home … Continue reading "Securitization"
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"
NickelodeonNickelodeon’s were the original movie theaters. Many had gaudy facades but, inside, they were dark dank rooms with wooden benches to watch short movies. Movies ran on a reel and people could watch as long as they wanted, or as long as they could stand the oftentimes filthy interiors. Possibly because Nickelodeon theaters are successors … Continue reading "Nickelodeon"
No-Till FarmingNo-till farming is an agricultural process where crops are planted over the prior crop without tilling. Background Since ancient times, farmers believed in the necessity of turning over the soil before planting. Shovels or plows turned over the prior crop, exposing the soil the next crop. Their belief was based on the idea that agricultural … Continue reading "No-Till Farming"
Internal Combustion EngineFew innovations throughout history are as important as the internal combustion engine. In 1807, the Niepce brothers received a patent on an internal combustion engine but failed to commercialize it. The brothers also invented photography. The first known working internal combustion engine (ICE) belongs to Lenoir. He converted a steam engine to burn coal gas … Continue reading "Internal Combustion Engine"
