Digital Video Recorder (DVR)Digital Video Recorders (DVR’s) record digitally, to disk or flash memory, rather than analog recording to tape. This allows end-users to quickly fast-forward, rewind, and jump to a section of a recording rather than slowly searching. Tivo and ReplayTV both launched DVR’s at the 1999 Consumer Electronics Show. As they did with videotapes, broadcasters and … Continue reading "Digital Video Recorder (DVR)"
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"
ImmunotherapyIt’s common for meaningful inventions to take years or even decades to reach their commercial potential. At about 110 years from discovery to practical use, immunotherapy is the second longest invention we’ve found after the Suez Canal. Immunotherapy is the process of training the body’s natural immune system to attack and destroy cancer cells. The … Continue reading "Immunotherapy"
Weather ForecastThe development of the telegraph in 1835 made weather forecasting possible. Before that time, people used various methods to guess changes in the weather. Some observations were accurate. For example, the correlation of barometric pressure to weather changes. However, there was not enough geographically widespread data to methodically forecast weather. The Britsh government charged Francis … Continue reading "Weather Forecast"
Transatlantic CablesTransatlantic cables shrunk the world, vastly increasing the speed and lowering the cost of intercontinental communications. The first cable functioned only a few weeks. Transmissions, in Morse Code, were especially slow. Field, as a young businessman, joined a paper company that failed six months later. Despite his status as a young employee, with no responsibility … Continue reading "Transatlantic Cables"
DynamiteDynamite blows up otherwise difficult to move things, like boulders, mountains, and bedrock. It lowers the cost of removing rocks to make level land and tunnels, railroads, roads, and enables foundations for skyscrapers. In 1847 chemists Théophile-Jules Pelouze and Ascanio Sobrero had synthesized nitroglycerin but the chemical was unstable and difficult to harness. Nobel encased … Continue reading "Dynamite"
Viagra (Sildenafil)It’s hard to write seriously about Viagra. No sooner did the drug help erectile dysfunction than it opened the opportunity for countless puns. Additionally, the name of co-inventor Albert Wood worsens the situation. However, in hindsight, Viagra cured a serious problem. Background Wood and Viagra co-inventor Peter Dunn were working on a blood pressure medicine. … Continue reading "Viagra (Sildenafil)"
Wire RopeWire rope is far stronger than natural-fiber rope. German mining engineer Wilhelm Albert invented wire rope about 1834. Wire rope is sometimes called Albert rope after the inventor. Early on, they were used to hoist stuff to and from silver mines in the Hartz Mountain. The first rope was three wrought-iron cables twisted around one … Continue reading "Wire Rope"
Pneumatic Tires1845 Robert Thomson The wheel is a seminal invention, widely regarded as one of the most important in human history. However, early wooden and stone wheels were far less useful than their modern air-filled rubber counterparts, the pneumatic tire. Despite their ubiquity today, it’s amazing that the pneumatic (air-filled) tire initially went all but unnoticed. … Continue reading "Pneumatic Tires"
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"
SemiconductorsSemiconductors are solid-state electronic replacements for vacuum tubes. They vastly enhanced productivity and lowered cost. Semiconductors also lowered the amount of electricity computers, or any equipment that ran on tubes, required. In 1947, John Bardeen, William Shockley, and Water Brattain co-invented the semiconductor while working at Bell Labs for which they were awarded the Nobel … Continue reading "Semiconductors"
Battery (Voltaic Pile)This was the first reliable and predictable source of electricity, a battery that generated its own power. It led to many future innovations. Most notable is the telegraph, that relied on voltaic piles as a power source. During the Civil War, wagons filled with giant batteries deployed to the front lines and powered telegraphs. Volta’s … Continue reading "Battery (Voltaic Pile)"
Social NetworkWhen they’re not rigging elections, sowing discord, or amplifying hate social networks are a fun, simple, and convenient way to stay in touch. However, they suffer serious privacy issues under current implementations. Electronic social networks, in various forms, are older than Facebook co-founder Mark Zuckerberg. The first online bulletin-board enabling people to chat and hang … Continue reading "Social Network"
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)"
Console Gaming SystemsConsole game systems are specialized computers that play games. Ralph Baer came up with the idea of a video-game system that connects to televisions in 1966. Magnavox agreed to manufacture and distribute his seventh prototype, in 1971, branded the Odyssey. Magnavox sold about 350,000 units, at the then steep price of $100, before discontinuing it … Continue reading "Console Gaming Systems"
