DNA SequencingDNA sequencing creates a map of DNA. The process reads DNA like a computer reads a hard drive. Eventually, the technology will allow scientists to understand and manipulate life functions. In 1955, Sanger discovered how to sequence DNA, which would later win him the Nobel Prize. He is one of four people in the world … Continue reading "DNA Sequencing"
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"
Automation: Robots in Real LifePart I, “Automation Armageddon: a Legitimate Worry?” reviewed the history of automation, focused on projections of gloom-and-doom. “It smells like death,” is how a friend of mine described a nearby chain grocery store. He tends to exaggerate and visiting France admittedly brings about strong feelings of passion. Anyway, the only reason we go there is … Continue reading "Automation: Robots in Real Life"
JukeboxThe Jukebox is an automated coin-operated music player which plays individual songs. The differentiating factor of the Jukebox from a simple coin-operated record player is the ability of an automated machine to replace live music in a restaurant or bar. Background Louis Glass and William Arnold modified Edison’s record players to operate by coins. These … Continue reading "Jukebox"
General Purpose CatalogBackground The general purpose catalog increased the selection and decreased the costs of small-town stores that could only afford to carry limited innovatory. Tiffany’s Blue Book is one of the oldest catalogs, from 1845. There were book, seed, and fabric catalogs in Europe dating back centuries. Ben Franklin created the first US catalog, for scientific … Continue reading "General Purpose Catalog"
Portable ComputerPortable computers are more convenient than stationary computers. They increase productivity for people who travel, allow office workers to bring work home, and enable telecommuting. Background Portable computers were developed at (where else), Xerox PARC. The Xerox NoteTaker, released in 1978, was the first portable computer. Staying true to Xerox tradition, only about ten were … Continue reading "Portable Computer"
Lithium-Ion BatteryLithium-Ion Batteries (LIBs) power everything from smartphones to power tools and electric cars. Entire cities store power generated during the day, via solar panels, for use at night from large lithium battery arrays. One of the largest factories in the world, the Tesla Gigafactory, is devoted solely to manufacturing Lithium-Ion batteries. Background An ability to … Continue reading "Lithium-Ion Battery"
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"
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)"
Inexpensive Postage & StampPenny postage refers to low-cost prepaid postage. Background By the early 1800s, postage was centuries old. But many postal carriers were essentially government couriers. They were extremely expensive. However, recipients could reject mail by refusing to pay. This made the entire system unpredictable and unstable. Furthermore, postal employees sometimes opened and read mail. Government censors … Continue reading "Inexpensive Postage & Stamp"
Vacuum Tube (Diode)Working for the Edison Electrical Light Company of England, Sir John Fleming invented the diode, a vacuum tube at the heart of all early electronics. Radios, television, telephones, computers – virtually every electronic we’re familiar with today – was first built with diodes. Diodes are typically vacuum tubes, though some have specialized gasses in them. … Continue reading "Vacuum Tube (Diode)"
Visual Web BrowserTim Berners-Lee original world wide web was entirely text-based, mainly used to link textual papers to one another. Mosaic Marc Andreesen, then a student at the University of Illinois Champaign-Urbana, extended Andreesen’s HTML. Andreesen extended the original HTML, adding components describing not only the contents of a page but also how it should be laid … Continue reading "Visual Web Browser"
Digital CameraIn 1975, Kodak employee Steven Sasson invented and patented the digital camera in 1975. Sasson’s camera used a CCD to capture 100×100 pixels and stored those on a cassette tape. He chose to store 30 photos per cassette due not to technical limitations but because Kodak sold film in 24 and 36 exposure rolls. Kodak … Continue reading "Digital Camera"
PhonographWe, the editors of innowiki, have reviewed thousands of inventions. We’ve read through countless idea, rejecting the vast majority not because they lacked merit but because they didn’t rock the world. Background Of the innovations we accept there are very few who have more than one invention. Granted, the raw number of innovations does not … Continue reading "Phonograph"
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"
