Charge-Coupled Device (CCD)1969 William BoyleGeorge Smith “We are the ones who started this profusion of little cameras all over the world.” William Boyle Charged Coupled Devices (CCD’s) are a special type of chip that reacts to light. They are inexpensive and especially useful in imagining, enabling digital photography and video. William Boyle and George Smith worked for … Continue reading "Charge-Coupled Device (CCD)"
Tractor Treads1904 Benjamin Holt “In the Roberts Island tract, where a man could not walk without sinking to his knees, and where tule-shoed horses could not be used, the new traction engine was operated without a perceptible impression in the ground.” Farm Implement News, May 18, 1905 “It looks like a caterpillar,” said a photographer observing … Continue reading "Tractor Treads"
Commercial Business Computer (EDVAC/UNIVAC)Mauchly and Eckert, inventors of the ENIAC, set out to create a commercial computer. They worked with government officials who needed fast computing, including military and census officials. Eventually, their employer, the University of Pennsylvania’s Moore School of Engineering announced an intent to keep all patents produced by faculty. Henceforth, the two promptly resigned and … Continue reading "Commercial Business Computer (EDVAC/UNIVAC)"
Audion TubeThe Audion acts as an amplifier, transforming quiet electric signals into loud ones. Background In 1906, Lee de Forest invented the “three-electrode Audion” vacuum tube. In 1906, Lee de Forest invented the “three-electrode Audion” vacuum tube. The Audion acts as an amplifier, transforming quiet electric signals into loud ones. Originally de Forest wasn’t quite sure … Continue reading "Audion Tube"
Three Phase PowerOne extra wire allows transmission of triple the amount of electricity via three-phase power. With three wires rather than two, electrical operators can transmit triple the electricity. “Polyphase” is another term for three-phase power. Three phase power usually transmits enormous amounts of electricity. These are the large transmission lines on tall polls. Electricity is converted … Continue reading "Three Phase Power"
Roll Film & Roll Film CameraKodak’s original camera contained plates. Later versions contained one-hundred exposures; customers would take their pictures, mail in their camera, and the company mailed back developed pictures and a refilled camera. Roll film changed all that, vastly lowering the cost and complexity of photography and eventually enabling the creation of movie film. Ordinary people could purchase … Continue reading "Roll Film & Roll Film Camera"
Coke Fueled Blast Furnace / Pig Iron1709 Abraham Darby used Coke instead of coal to fire blast furnaces, making the production of iron from pig iron (a weak iron), much more economical. Coke burns significantly hotter than coal which, combined with his new design to concentrate the heat, his factory was significantly more efficient than prior methods. He created the Bristol … Continue reading "Coke Fueled Blast Furnace / Pig Iron"
Index Investment Funds“Don’t look for the needle in the haystack. Just buy the haystack!” Index investment funds are simpler and vastly less expensive than individual stock picking. Firms mimic index funds which, themselves, are created to mimic market strength. Not only do 85 percent of hedge fund managers trail returns in the S&P 500 but also they … Continue reading "Index Investment Funds"
Chemical WarfareChemical warfare refers to using chemicals as a weapon of mass destruction, killing many people at once. Fritz Haber, the inventor of the ammonia extraction process, is also the father of modern chemical warfare. On Jan. 31, 1915, Germany used a type of tear gas on allied troops. Due to the temperature, the chemicals failed … Continue reading "Chemical Warfare"
Heart-Lung Machine / Cardiopulmonary BypassHeart-Lung machines temporarily do the work of the heart and lungs allowing surgeons to operate on the heart or lungs. Despite the sci-fi nature, it was a husband-wife garage invention. Background In 1931, surgeon John Gibbon lost a patient he felt sure would have lived if he could temporarily keep blood circulating and oxygenated. He … Continue reading "Heart-Lung Machine / Cardiopulmonary Bypass"
- Blue Ocean Strategy Basics – Making Competition Irrelevant
A different way of thinking. It’s right there on the front of the jacket of the book Blue Ocean Strategy, “How to Create Uncontested Market Space and Make the Competition Irrelevant.” It’s also one of the most misunderstood concepts of blue ocean strategy. I’ve been working on blue ocean strategy since 2001, when it was … Continue reading "Blue Ocean Strategy Basics – Making Competition Irrelevant"
High-Yield Rice (IR8)Asia was on the edge of an epic famine large enough to cause widespread death and civil unrest. Both the Ford and Rockefeller Foundation responded by founding and funding a thinktank to create higher-yield rice, the International Rice Research Institute (IRRI). Straightaway, they sent a team of mainly American scientists to research if anything could … Continue reading "High-Yield Rice (IR8)"
Wind-Driven SawmillCornelis Corneliszoon van Uitgeest invented a sawmill driven by a windmill. It cut wood about 30 times faster than sawing by hand. Corneliszoon received a patent for his wind-driven sawmill. Workers found the mill during a 2004 excavation. The windmill used a crankshaft to convert the steady wind into the up-and-down motion necessary to saw … Continue reading "Wind-Driven Sawmill"
LinuxLinux is a stable and secure operating system. The operating system is open-source and free. However, there are many companies that sell support for Linux, and maintenance is typically the source for most of the cost comes of maintaining an operating system. Background Limited to 16 concurrent users at his school’s computer, Linus wanted a … Continue reading "Linux"
Pneumatic Tires1845 Robert Thomson The wheel is a seminal invention, widely regarded as one of the most important in human history. However, early wooden and stone wheels were far less useful than their modern air-filled rubber counterparts, the pneumatic tire. Despite their ubiquity today, it’s amazing that the pneumatic (air-filled) tire initially went all but unnoticed. … Continue reading "Pneumatic Tires"
