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)"
Electricity Factory & Distribution NetworkAfter inventing the long-lasting light bulb, Edison needed an electrical grid to deploy his innovation. Remember that, at this time, all electrically powered devices ran off batteries. Background The Edison Electric Illuminating Company, founded after the light bulb company, funded both an electrical generation station, grid, and all supporting equipment. Edison innovated better dynamos, circuits, … Continue reading "Electricity Factory & Distribution Network"
Web Search EngineNoteworthy early search engines include Archie, from 1990, that searched filenames, and Gopher, from 1991, that organized files. Early Search Engines In March 1994, Stanford students David Filo and Jerry Yang created “Jerry and David’s Guide to the World Wide Web.” Their website contained lists arranged by category of the burgeoning World Wide Web. Sites … Continue reading "Web Search Engine"
- Fourdrinier Paper Making Machine
Fourdrinier machines transform wood pulp into enormous rolls of paper. They vastly reduced the manufacturing cost and, subsequently, the price of paper. Even the smallest Fourdrinier machine is massive and requires an enormous amount of water. Frenchman Louis Roberts invented the papermaking machine. His friend and confidant, Sealy Fourdrinier, patented and commercialized the technology in … Continue reading "Fourdrinier Paper Making Machine"
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)"
ChemotherapyChemotherapy refers to a group of drugs that fight cancer. Surgery and radiation were the two common anti-cancer therapies before the discovery of effective chemotherapy. Immunotherapy was also studied but showed little promise. Background In the 1800s, scientists thought drugs might be able to fight cancer. However, none of them worked well. In the 1910s, … Continue reading "Chemotherapy"
Electronic Maps – Geographic Information Systems (GIS)Electronic maps simplify planning and routing. They lower the cost of transportation by sharply reducing the cost of getting lost. Furthermore, they allow optimization of store and advertisement placement. The reason Starbuck’s always seems to be “on the way” is due to the use of GIS. Dangermond found Environmental Systems Research Institute (ESRI) in 1969 … Continue reading "Electronic Maps – Geographic Information Systems (GIS)"
Optical Character Recognition (OCR)Optical Character Recognition (OCR) technology increases productivity and decreases cost by alleviating the need for humans to type printed information into computers. It also reduces the risk of typos. David Shepherd’s OCR machine was used in few places. Most notably, Reader’s Digest used it to manage subscription information, transforming printed material to punch cards. Other … Continue reading "Optical Character Recognition (OCR)"
Gas MaskGas masks lower the risk of damage for firefighters and soldiers. Garret Morgan, the son of freed slaves, developed an early gas mask for use in fires. Hoses dragged along the ground where air was cleaner, because smoke rises. There was also a 15-minute air supply for when air became hopelessly polluted. Patented in 1914, … Continue reading "Gas Mask"
SecuritizationSecuritization enables income streams of pooled loans, reducing overall risk to lenders. This spreads the risk of both prepayments and defaults, lowering the cost of credit. Background Denmark created pooled mortgages, called covered bonds, in 1850. Switzerland followed in 1930. In 1970 US government pseudo-agency Ginnie Mae (GNMA) created the first securitized pool of home … Continue reading "Securitization"
Postal System1497 Franz von TaxisHenry BishopRowland HillWilliam Dockwra Franz von Taxis created the postal system, with regular routes between far-flung cities throughout Europe. Eventually, von Taxis mail routes included mail delivery between Brussels and: Innsbruck, 5.5 days (6.5 days winter) Paris, 44 hours (54 hours winter) Blois, 2.5 days (3 days winter) Lyon, 4 days (5 … Continue reading "Postal System"
Assault RifleAssault rifles can shoot repeatedly and rapidly without reloading. Nazi’s realized that in most fire-fights soldiers were less than 400 meters. While traditional machines guns could shoot considerably further, their range was unhelpful. Furthermore, the weight of both the weapons and ammunition became a liability. In response, Nazi’s invented a light weapon with smaller and … Continue reading "Assault Rifle"
Global Positioning System (GPS)GPS uses satellites to compute positioning in 3D space, allowing automatic mapping and advanced navigation. The Soviet Union launched the Sputnik satellite on October 4, 1957. Sputnik did nothing but send out radio pings audible on radio receivers on earth. Conveniently, they launched the satellite to fly over then arch-enemy the United States. As scientists … Continue reading "Global Positioning System (GPS)"
Turing Complete Mechanical Computer (Z1, Z2, Z3, Z4)The Z-series computers are notable as the first recognized as the first “Turing complete” (modern) computer. The Nazis did not see the computer as strategically important and invested little in it. The company survived the war but there was little demand for their machines. They eventually sold the patents to the Americans. Zuse worked for … Continue reading "Turing Complete Mechanical Computer (Z1, Z2, Z3, Z4)"
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"
