Sit-Flat Paper BagsSure, sit-flat paper bags are not the condensing steam engine, the telegraph, pneumatic tools, or the dynamo generator but they represent something new: a woman entrepreneur. After realizing the hassle of bags that would not stand Margaret Knight set out to create a machine for a bag with a flat bottom. She worked with three … Continue reading "Sit-Flat Paper Bags"
eLearning / Computer Based Training, PLATOIn 1960, Prof. Donald Bitzer introduced an educational computer system, the Programmed Logic for Automatic Teaching Operations, PLATO. In hindsight, PLATO is arguably one of the least known but most important technological advances ever. Countless elements of the world wide web were first introduced via PLATO. Background Bitzer was a professor of electrical engineering at … Continue reading "eLearning / Computer Based Training, PLATO"
Autonomous Vehicles (Self-Driving Cars)DARPA, the US government agency that invented the internet (among other things) created a contest to build a self-driving car. The first DARPA Grand Challenge, in 2004, was a 150 mile (240 km. route). The robot-car that drove the furthest before breaking down, built by Carnegie-Mellon University (CMU), lasted 11.78km. Undeterred, DARPA tried again. Subsequently, … Continue reading "Autonomous Vehicles (Self-Driving Cars)"
Container ShippingBefore container shipping, trucks were manually unloaded by longshoremen, loaded onto ships, and the process repeated at the destination. This added enormous cost, slowed shipping times and increased the risk of breakage. Inspired by WWII standardization, McLean designed containers that fit directly on ships. His standardized containers and ships enable faster and less expensive loading … Continue reading "Container Shipping"
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)"
Steam Engine (Newcomen)The Newcomen steam engine removed water from mines. It worked but was extremely inefficient. Steam was not recycled (re-condensed) so the Newcomen engine required an enormous amount of coal to continually boil water. When used at a coal mine, where scrap coal was essentially free, this cost less than having workers remove water by the … Continue reading "Steam Engine (Newcomen)"
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)"
Breach Loaded FirearmsFlintlock guns required the user to pour gunpowder into the barrel of the weapon, stamp it down, add a bullet, then carefully pick the whole thing up and fire it. By the time all that finished, soldiers could be chased down and stabbed with a knife. Breach-loading firearms opened the rifle near the back. They … Continue reading "Breach Loaded Firearms"
Automated Flour MillOliver Evans’ mill vastly lowered the cost while increasing the quality of flour. These mills automated the milling of flour much like Arkwright automated the creation of fabric. The automatic mills were popular with farmers. Evans automated mill reduced the time and increased the quality and consistency of flour. George Washington purchased one that is … Continue reading "Automated Flour Mill"
BasketballWe only have two sports on innowiki we think merit inclusion, football (soccer in the US and Australia) and basketball. Global diffusion is the reason for their inclusion. Of course, there are countless regional sports. Fierljeppen is our favorite. However, no matter the appeal of canal jumping, football and basketball are the only two that … Continue reading "Basketball"
Transistor RadioDeveloped in 1947 but commercialized in 1954, transistor radios are small. Battery-operated portable radios that fit in a pocket. They rely on transistors rather than vacuum tubes. There were several attempts to build radios with transistors but none were optimal until 1954. Eventually, a Texas Instruments team invented the Regency TR-1, the first radio miniaturized … Continue reading "Transistor Radio"
Options & Futures“I’ll gladly pay you Tuesday for a hamburger today,” cartoon character Wimpy Wellington repeatedly offers. If he worked as an options trader he’d probably say “I’ll gladly pay you 1/10th the price of a hamburger today if I can buy a hamburger, sometime in the next year, at the price they are today.” You’d answer: … Continue reading "Options & Futures"
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)"
Spread Spectrum Frequency Hopping1941 Hedwig Eva Maria Kiesler (Hedy Lamarr)George Antheil Spread spectrum frequency hopping synchronizes devices to speak over changing frequencies. The technology jumps from one frequency to another in a predetermined but predictable manner so that the sender and recipient can change simultaneously. Lamarr and Antheil created the technology to contribute to the WWII effort, though … Continue reading "Spread Spectrum Frequency Hopping"
Random Access MemoryRandom Access Memory (RAM) is a type of fast memory. The Central Processing Unit (CPU), the brain of a computer, relies on RAM. RAM exists to this day. Every computer, including smartphones, contains RAM. The “random” in RAM refers to its ability to access memory anywhere, instantly, unlike a disk drive that must search for … Continue reading "Random Access Memory"
