Nuclear Aircraft CarrierNuclear aircraft carriers are enormous ships capable of traveling the world indefinitely. Indeed, the ships feature relatively large flight-decks capable of launching and landing fixed-wing aircraft, typically fighters. At 1,123 ft. (342 m.) the USS Enterprise is an enormous ship. In contrast, only oil supertankers are larger. The Enterprise supported 4,600 service members. First launched … Continue reading "Nuclear Aircraft Carrier"
Movable Type Printing PressBackground Gutenberg’s father was a minor royal and his mother came from a merchant family; they lived in Mainz, Germany. His father was in charge of running an ecclesiastical mint; they created coins. Growing up, Guttenberg was essentially a jeweler. Gutenberg’s father died in 1419, leaving an inheritance but also a problem. Guttenberg’s father was … Continue reading "Movable Type Printing Press"
MotorcycleAfter engineering a buggy that runs on four wheels it didn’t take long to realize a motorized bicycle would work well. Motorcycles are more efficient than cars: they use less fuel and take less space. However, they’re more dangerous than cars, offering far less protection in the event of a crash. They’re also fun. In … Continue reading "Motorcycle"
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"
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"
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"
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"
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"
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"
Programmable Machine (Jacquard Loom)The Jacquard Loom is a seminal invention in the history of modern computers. Automation technology existed long before the loom but the automation was simple repetition. For example, pull the loom up, push a thread through, pull the loom down, and push another thread through then repeat. Different color threads might be used on different … Continue reading "Programmable Machine (Jacquard Loom)"
Microwave OvenPercy Spencer is a self-taught engineer who did not finish even primary school. He self-taught himself math, science, and electrical engineering while standing guard on ships in the Navy. Before, during, and after WWII, Spencer worked on top-secret magnetrons, the high-powered electrical devices at the heart of a RADAR system. One day he noticed that … Continue reading "Microwave Oven"
Blue Ocean Strategy & Finance: Margin LendingMargin lending refers to the process of using borrowed money for investing. For example, a traditional investor may purchase 100 shares of a business for $10, spending $1,000. However, using margin, that same person may purchase 150 shares, spending the same $1,000 and borrowing another $500. If the stock price goes up, they pay the … Continue reading "Blue Ocean Strategy & Finance: Margin Lending"
Time-Sharing/Multitasking ComputerEarly Computers Early computers stored programs and data on punch cards. Most cards contained 80-characters, which is why early terminal programs were typically 80-characters per line. Punch cards are exactly what they sound like, physical cards. Each card is one line of a computer program or one piece of data. As users typed, a machine … Continue reading "Time-Sharing/Multitasking Computer"
Long Playing (LP) Records & Talking MoviesLong-playing records play for a long time, enabling records with more than one song. Background As Edison’s phonograph evolved, the recordings eventually migrated to small disks played at 78 rotations per minute (rpm). Each disk held about three minutes of music per side. Filmmakers wanted to add sound to their movies. Before then, movies ran … Continue reading "Long Playing (LP) Records & Talking Movies"
StatinsStatins dramatically lower blood cholesterol, and the likelihood of heart attacks. Akira Endo discovered statins. Akira Endo & His Molds Endo is a Japanese researcher with a lifelong fascination related to fungi. Recalling that Fleming accidentally discovered penicillin, he theorized that fungi might hold other miracle drugs. Endo noted that Americans are much heavier than … Continue reading "Statins"
