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)"
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"
PlasticAs described in the post about rubber, Charles Goodyear created the vulcanization plastic making mass-market rubber possible. Goodyear’s durable rubber enabled an entire field of new products from tires to raincoats. However, rubber is both thick and spongy, giving it limited utility. Nobody is going to create a rubber telephone and a rubber water bottle … Continue reading "Plastic"
- Blue Ocean Strategy Basics – Breaking the Value/Cost Trade-Off
Oftentimes spending more doesn’t get more and, sometimes, gets less Michael Porter is the father of modern business strategy theory and defined a few basic ideas. Core among them is that business centers around competition. Competitors, new market entrants, suppliers, customers, and substitute products are five forces that influence profitability, he argued in his famous … Continue reading "Blue Ocean Strategy Basics – Breaking the Value/Cost Trade-Off"
24-Hour NewsBroadcast news was a staid affair, a half-hour visual summary showing events of the day. American networks NBC, ABC, and CBS each had a newscast and each aired at the same time. Ted Turner inherited an outdoor advertising company. To build more advertising outlets he purchased a third-rate television station running old TV series and … Continue reading "24-Hour News"
TelevisionBefore Farnsworth, there were various types of mechanical TV that used spinning disks (Nipkow disks) and electrical transmitters, none of which ever gained traction. John Logie Baird invented the most widely known mechanical TV. Electrical Television Farnsworth had a small group of innovators, who invested $25,000. They eventually told him to give up so he … Continue reading "Television"
Mass Market Broadband Internet (DSL & Cable Modems)Broadband definitions continually change, but in 2017 the US definition of broadband is 25Mbps (megabytes per second) downstream and 3Mbps upstream. This is fast enough to stream music, movies, web surf, and read blurbs on innowiki. Background Early internet users used slow dial-up modems. The last mass-produced dial-up model ran at 56Kbps, about 1/450th the … Continue reading "Mass Market Broadband Internet (DSL & Cable Modems)"
Inkjet PrinterInkjet printing produces affordable, high-quality printouts using low-cost personal desktop printers. Background Ichiro Endo, of Canon, was the first to realize the idea that ink could be heated to form a small bubble, then deposited on a page to form a pixel, inkjet printing. John Vaught, a college dropout working at Hewlett-Packard, was working on … Continue reading "Inkjet Printer"
LASERLASER’s allow light to be intensely focused. There are many uses, from reading digital media at low power to cutting at higher powers. Countless applications rely on LASER technology. In 1957, Arthur Schawlow and Charles Townes, of Bell Labs, worked on an infrared LASER, called an “optical MASER.” They patented the invention in 1958. In … Continue reading "LASER"
BakeliteBakelite enabled inexpensive mass production at very high tolerances where interchangeable parts matter (ex: telephones, radios, plugs, pens, wristbands, insulators, etc…). Also, it looked fun compared to organic materials in use before Bakelite. Baekeland’s Bakelite opened the “age of plastics.” It was moldable into any shape and, once molded, kept its shape. It did not … Continue reading "Bakelite"
The Role of Education in Automation TechPart I, “Automation Armageddon: a Legitimate Worry?” reviewed the history of automation, focused on projections of gloom-and-doom. Part II, “Automation: Robots in Real Life” reviewed how robots are ubiquitous and create jobs. My first real job was creating a print estimating and production control system for five print plants scattered around the US. Each had … Continue reading "The Role of Education in Automation Tech"
Multi-Shot Revolver“God created men equal, Sam Colt made them equal.” Samuel Colt Overview Colt’s revolver reduced the cost and risk of settling the US. Before the revolver, Native Americans could shoot arrows faster than pioneers could reload muskets, making westward travel and settlement dangerous. The Colt revolver reversed the dynamics and is widely credited with winning … Continue reading "Multi-Shot Revolver"
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"
DefibrillatorClear! Defibrillators are the electric paddles that restart hearts. In 1957, Dr. Pantridge and Dr. John Geddes invented cardiopulmonary resuscitation (CPR). Eventually, he went on to innovate a portable defibrillator that weighed 70kg and ran from car batteries, installing it in a Belfast ambulance. No sooner did the devices prove effective then, by 1968, they … Continue reading "Defibrillator"
Audion TubeThe Audion acts as an amplifier, transforming quiet electric signals into loud ones. Background In 1906, Lee de Forest invented the “three-electrode Audion” vacuum tube. In 1906, Lee de Forest invented the “three-electrode Audion” vacuum tube. The Audion acts as an amplifier, transforming quiet electric signals into loud ones.
