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)"
Dry Cell BatteryDry cell batteries are the batteries the world is familiar with, the one’s that run portable electronics. Voltaic pile batteries, that preceded dry-cell batteries, required constant maintenance. Background To contextualize this era, the telegraph was gaining widespread adoption. However, there was no power grid to run the telegraphs at this time. The first power plant, … Continue reading "Dry Cell Battery"
Rechargeable Battery1859 Frenchman Gaston Planté invented the lead-acid rechargeable battery. In the early years, his battery lacked commercial value. Planté’s battery stored electricity and recharged easily but tended to release the electric in enormous bursts that, at the time, offered limited utility value. Before the Planté battery was the Voltaic Pile and later derivatives. These were … Continue reading "Rechargeable Battery"
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)"
Portable VentilatorVentilators breathe for people when they cannot breathe on their own. John Emerson was a physician focused on breathing devices who developed the first mass produced iron lung. Building on Emerson’s work, Bird developed the portable ventilator and, later, created a company, Bird Corp., to commercialize it. Bird Corp. created a home ventilator in 1965, … Continue reading "Portable Ventilator"
FM RadioHistory In 1906, Lee de Forest invented the “three-electrode Audion” cathode ray tube. However, by his own admission, saw no use for it in radio. During his time at Columbia, Armstrong worked with Audion tubes and realized they could recycle a radio signal, amplifying it by sending it repeatedly through the tube. Further, by reversing … Continue reading "FM Radio"
Plasma Panel1964 Donald BitzerGene SlottowRobert Wilson Plasma panels form fonts, images, and other patterns using plasma, rather than tubes. The panels are flat, cool, and use less power than CRT tubes. Bitzer developed the plasma panel as the monitor for his teaching computer, PLATO. PLATO is a lesser-known fountain of innovation. Along with Bell Labs, Xerox … Continue reading "Plasma Panel"
Photocopiers“Xerography was an invention we didn’t know we needed until, suddenly, we didn’t know how we lived without it.” Carlson biographer David Owen Chester Carlson Chester Carlson had a childhood nobody would want to copy. His father was perennially ill and poor. Mom, dad, and young Chester lived in a leaky hut in Mexico until … Continue reading "Photocopiers"
Reasonably Priced Business Computer (IBM/360)The IBM/360 is the first mass computer, designed as a general-purpose computer affordable for mid-sized businesses yet powerful enough for large enterprises. Background In 1962, IBM’s revenue was $2.5 billion. CEO Thomas Watson Jr. believed in the vision of a general-purpose computer that supports timesharing, the ability of a computer to do multiple things at … Continue reading "Reasonably Priced Business Computer (IBM/360)"
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"
Floppy DiskFloppy disks allowed inexpensive, portable storage of digital information. Floppies were faster, more flexible, more convenient, and lower cost than tape drives. Floppy drives made computers simpler to use, more convenient and increased productivity for computer operators who did not have to load tapes. Noble invented the floppy disk as an IBM engineer. His first … Continue reading "Floppy Disk"
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)"
Digital Mobile PhoneDigital mobile phones vastly reduce the cost of mobile phones by enabling many more phones to utilize the same number of towers. After the successful launch of analog mobile phones, the need for a digital standard quickly became apparent. Digital phones are smaller, use less power, and require fewer towers. There are two mobile digital … Continue reading "Digital Mobile Phone"
MusketWhile Guttenberg’s forge was working to bring about the Renaissance, a more common use was to create weapons to kill one another. One of the most noteworthy is the musket. Background Early muskets were more like small cannons than the later-day rifles. Sometimes two-people needed to operate the earliest weapons due to their weight. Armies … Continue reading "Musket"
Interpress & PostScriptInterpress and PostScript enabled display technology, initially printers and eventually screens, to display output exactly as it would look between media. Printouts and screens, no matter the size, would look exactly the same. The technology is another from Xerox PARC. Background Warnock left Evans & Sutherland, a computer graphics company founded by Ivan Sutherland, to … Continue reading "Interpress & PostScript"
