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)"
Polyethylene Terephthalate (PET Plastic bottles)PET plastic reduced the cost and weight of beverage containers. Originally, only glass and metal containers were suitable for storing carbonated drinks. Other plastics would bulge and break. However, PET plastic enabled plastic bottles suitable for carbonated drinks. Soon, it became used for all beverages. In the 1960s, plastics engineer Wyeth questioned whether carbonated drinks … Continue reading "Polyethylene Terephthalate (PET Plastic bottles)"
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"
Core MemoryCore memory enhanced the productivity of early computer operators. Not only does core memory store information but also does not need power to maintain memory. Wang & Woo created computer memory that would sit on tiny magnetic rings, strung together into cores. These were smaller than vacuum tubes and used less power. Furthermore, they did … Continue reading "Core Memory"
Caravel Oceanic ShipBefore the Caravel, ships were limited to coastal navigation. The Caravel, with its relatively small hull and large sails, enabled long-distance navigation over large bodies of water; it was the jetliner of its era. Invented in the mid-1400s, the Caravel — among other things — enabled Columbus to navigate from Europe to North America. Other … Continue reading "Caravel Oceanic Ship"
Polymerase Chain Reaction (PCR)Polymerase Chain Reaction (PCR) turns a tiny bit of DNA into a much larger amount which can subsequently be sequenced. In 1983, Mullis figured out a way to multiply the tiniest piece of DNA by orders of magnitude, making millions of copies. This is how the smallest bit of DNA, from bacteria, viruses, historical artifacts, … Continue reading "Polymerase Chain Reaction (PCR)"
Magnetic Tape RecordingPoulsen, a Danish engineer, created and patented a machine that recorded onto magnetic tape. His called the invention a Telegraphone. There was no amplification and the recording quality was poor. In 1928, Pfleumer, a German, vastly improved the magnetic tape. He named his device a Magnetophone. During WWII the Germans used it for communications and … Continue reading "Magnetic Tape Recording"
BicycleProlific innovator Karl Drais invented the bicycle, first without pedals then, later, with. He also invented the typewriter w/ keyboard, first stenograph, and player-less piano. Drais was a civil servant ineligible for patent protection but was given patents and a pension. However, he found himself on the wrong side of a Prussian war, going so … Continue reading "Bicycle"
Portland Cement1843 Joseph AspdinWilliam AspdinWilliam Beverley Portland cement is modern cement. It’s admittedly dull — unless being used on dilapidated ships by mobsters for shoes — but extremely useful with more mainstream uses. Portland cement is used to make buildings, stadiums, stairs, sidewalks, foundations, and shares the unfortunate honor of being the enabler of brutalist architecture. … Continue reading "Portland Cement"
Optical Character Recognition (OCR)Optical Character Recognition (OCR) technology increases productivity and decreases cost by alleviating the need for humans to type printed information into computers. It also reduces the risk of typos. David Shepherd’s OCR machine was used in few places. Most notably, Reader’s Digest used it to manage subscription information, transforming printed material to punch cards. Other … Continue reading "Optical Character Recognition (OCR)"
Supertall SkyscraperBuildings higher than 300 meters (984 ft.) are supertall skyscrapers. During the late 1920s there was an unofficial competition to see who could build the tallest building in New York City. Background In 1913, the Woolworth Building was the highest in New York City, at 792 feet. New York architects William Van Alen and Craig … Continue reading "Supertall Skyscraper"
InternetNikola Tesla and J.C.R. Licklider both talked about a worldwide network of computers. Licklider referred to it as an “Intergalactic Network.” Background The internet evolved slowly over time. At first, it wasn’t much more than a series of specifications, ideas about how computers might talk to one another. Eventually, towards the late 1960s, these turned … Continue reading "Internet"
Gyroscopic Navigation (Autopilot)Gyroscopic navigation enables planes and ships to stay on a straight course without human intervention. Long before GPS, airplane pilots used compasses and waypoints to navigate. Natural landmarks or even giant arrows guided planes when to turn and in which direction. Of course, between waypoints, it was necessary to fly straight or the pilot would … Continue reading "Gyroscopic Navigation (Autopilot)"
Panama CanalThe 80 km. (50 mi.) long Panama Canal connects the Atlantic and Pacific oceans, avoiding the need to sail around South America. Background Unquestionably, the French were stoked after their completion of the Suez Canal. Given that the project took 3800 years from start to finish their enthusiasm is understandable. Subsequently, they decided to undertake … Continue reading "Panama Canal"
Cotton GinWhitney’s innovation vastly lowered the price of cotton. Before Whitney’s cotton gin, producing cotton was economically inefficient because of the enormous cost to separate cotton from seeds. After the innovation, cotton became a profitable crop. Background Coming of age during the Revolutionary War, Whitney made a nail company, at the age of 15. Later, he … Continue reading "Cotton Gin"
