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"
Computer Assisted Design (Sketchpad)“The cinema camera doesn’t make movies; it allows movies to be made. It’s the creative people who make it real to people.” Ivan Sutherland Computer Assisted Design (CAD) uses mathematics to do the geometry and calculations necessary to draw and design. CAD is faster and more accurate than hand drawing. Sutherland’s “sketchpad” software, part of … Continue reading "Computer Assisted Design (Sketchpad)"
Ballpoint PenBallpoint pens are modern pens, where ink a tube coats a ball at the end which writes. Unlike fountain pens they are inexpensive and require no skill beyond the ability to write. Loud, an American Harvard-educated lawyer, invented and patented the ballpoint pen but failed to commercialize the pen. Other versions were released but none … Continue reading "Ballpoint Pen"
AirshipSporting both bodacious name, mustache, and title of nobility, Count Ferdinand von Zeppelin forever changed air travel. Zeppelin wasn’t the first to try making hot air balloons more maneuverable. That honor belonged to Frenchman Henri Giffard. Basically, a big cigar-shaped balloon, Giffard’s airship was the first aircraft that enabled navigation. In 1882, with declining health, … Continue reading "Airship"
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"
Synthetic DyeAs the Industrial Revolution gained steam (OK – bad pun), England’s population became denser. Eventually, the resulting pools of water bred mosquitos that eventually became a malaria epidemic. Perkin, a 15-year-old student, ran crude experiments to create lower-cost quinine, a malaria medicine. One of his processes accidentally produced a strong purple liquid. Useless as a … Continue reading "Synthetic Dye"
Heavy-Duty DC Motor / Trolley / SubwayFaraday proved an electric motor was possible but, like his many inventions, neither scaled the idea up nor commercialized it. Voltaic piles at that time were the sole source of electricity. Because they produced little electricity high-power motors seemed pointless. Background The new field of electricity interested Sprague, a Navy officer. While serving in the … Continue reading "Heavy-Duty DC Motor / Trolley / Subway"
Game TheoryGame theory serves as the foundation of systematized decisionmaking and modern economics. Indeed, Minimax game theory underlies modern economics and is responsible for countless economic insights, many of which won Nobel Prizes. Besides game theory, von Neumann eventually modeled the lenses behind the Los Alamos plutonium nuclear bomb. As a Jewish refugee from Europe whose … Continue reading "Game Theory"
Polyethylene PlasticPolythene (PE) is the world’s most common plastic. Plastic bags, packaging cups, plates are all made from polyethylene plastic. Only carbonated beverage bottles use a different type of plastic because PE does not expand well. Despite its ubiquity today, PE has an odd history. It was an accidental discovery by Reginald Gibson and Eric Fawcett … Continue reading "Polyethylene Plastic"
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)"
Screw PropellerScrew Propellers vastly reduced the amount of power needed to move ships. The propellers look like fans and work on similar principles except they displace water instead of air. Countless people, from James Watt onward, claim to have invented the screw propeller. Early experiments, in the late 1700s and early 1800s, functioned but propelled ships … Continue reading "Screw Propeller"
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"
Spinning JennySpinning Jenny’s are significantly more efficient spinning wheels, allowing wool to be produced at a much lower price. Each Jenny did the work of multiple spinners. The Jenny (slang for Engine in British English) was unwelcome in Hargreaves’ village because it caused yarn prices to decline. Chased by angry tradesmen, he fled from the spinning … Continue reading "Spinning Jenny"
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"
LithographyLithography allows highly detailed drawings to be inexpensively reproduced at high volumes. Before lithography, printing remained similar from Gutenberg until Senefelder’s lithographic process. Senefelder worked as an actor and playwright. Unable to earn a living, he turned to printing as a trade but could not afford the typographic fonts and materials. Frustrated, he started experimenting … Continue reading "Lithography"
