DDT“We are accustomed to look for the gross and immediate effects and to ignore all else. Unless this appears promptly and in such obvious form that it cannot be ignored, we deny the existence of hazard. Even research men suffer from the handicap of inadequate methods of detecting the beginnings of injury. The lack of … Continue reading "DDT"
UnixUnix is a computer operating system. Among other things, it allows a computer to do many things at once. Derivatives of the original Unix include Linux, MacOS, and BSD. You’re reading this right now due to a server running Unix derivative Linux. Background Dennis Ritchie and Ken Thompson worked at Bell Labs. Thompson worked on … Continue reading "Unix"
AirshipSporting both bodacious name, mustache, and title of nobility, Count Ferdinand von Zeppelin forever changed air travel. Zeppelin wasn’t the first to try making hot air balloons more maneuverable. That honor belonged to Frenchman Henri Giffard. Basically, a big cigar-shaped balloon, Giffard’s airship was the first aircraft that enabled navigation. In 1882, with declining health, … Continue reading "Airship"
SmartphoneIn 1909, Nicola Tesla described what eventually would be a smartphone. They’ve existed in various forms for many years. History IBM invented a phone called the Angler in 1992 with PDA like functions. Subsequently, they released a commercial version in 1994. The term “smartphone” first appears in 1995 describing AT&T’s PhoneWriter Communicator. Eventually, more phones … Continue reading "Smartphone"
Suez CanalThe Suez Canal connects the Arabian and Red Sea to the Mediterranean. The canal is one of the two most important human-engineered waterways in the world. Background Think your remodel took a long time? Or your software project went horribly over time and budget? Maybe a movie took too long to make? North Korea has … Continue reading "Suez Canal"
FiberglassFiberglass has multiple uses. It acts as an insulator, building material, and even boat hulls. First, in 1870, John Player developed a process to mass-produce glass strands with seam jets used for insulation. By and large, this is arguably the first fiberglass. Eventually, in 1880, Herman Hammesfahr patented weaving glass fibers to silk, making it … Continue reading "Fiberglass"
ParachuteParachutes lowered the risk of flight, encouraging innovation in flying. In 1782, the Montgolfier brothers launched the first hot air balloon from the grounds of the Palace of Versailles. King Louis XVI and Marie Antoinette — the last of the French aristocracy who would be beheaded during the revolution — watched as the balloon lifted … Continue reading "Parachute"
BroadcastingDavid Sarnoff David Sarnoff is the father of broadcasting. Sarnoff was a Jewish immigrant who became his family’s breadwinner at age 15. He worked as a Morse Code operator, rising up the ranks to become a supervisor. Eventually, he transitioned to radio to transmit messages over long distances. Early radio technology was for point-to-point communications, … Continue reading "Broadcasting"
Panama CanalThe 80 km. (50 mi.) long Panama Canal connects the Atlantic and Pacific oceans, avoiding the need to sail around South America. Background Unquestionably, the French were stoked after their completion of the Suez Canal. Given that the project took 3800 years from start to finish their enthusiasm is understandable. Subsequently, they decided to undertake … Continue reading "Panama Canal"
- Blue Ocean Strategy Basics – Buyer Experience Cycle
Put yourself in the shoes of your buyer The Buyer Experience Cycle (BEC) is a superficially short and often overlooked blue ocean exercise. In the books, tutorials, and even the tool itself, the BEC is always coupled with the Buyer Utility Map though they’re separate parts of the exercise. In short, the BEC is a … Continue reading "Blue Ocean Strategy Basics – Buyer Experience Cycle"
Portable ComputerPortable computers are more convenient than stationary computers. They increase productivity for people who travel, allow office workers to bring work home, and enable telecommuting. Background Portable computers were developed at (where else), Xerox PARC. The Xerox NoteTaker, released in 1978, was the first portable computer. Staying true to Xerox tradition, only about ten were … Continue reading "Portable Computer"
Integrated Circuits (Microchips)In early electronic computers, each circuit involved a vacuum tube. They were large, relatively slow, and consumed a lot of power. Shockley, Brattain, and Bardeen created the semiconductor. Their circuits eliminated the need for vacuum tubes. Kilby and Noyce discovered that semiconducting material held burned-in semiconductor circuits. Their printed circuits worked like the much larger … Continue reading "Integrated Circuits (Microchips)"
Credit UnionLet it not be forgotten that a credit union is, above all else, an association of people, not dollars. Alphonse Desjardins Banks at the turn of the 20th century were for rich people. A.P. Giannini founded his Bank of Italy, later renamed Bank of America, in 1904 as a bank for everybody else. But it … Continue reading "Credit Union"

He also experimented with helicopters, airplanes, and amusement park rides. While on vacation in Vienna he claims another American told him “If you want to make a … Continue reading "Machine Gun"
Electric Arc WeldingElectric arc welding lowered the price of joining metal pieces, eventually enabling the construction of much larger structures. Russians love to build giant things, bolshoya as they say in Russian. Therefore, it makes sense that it was a Russian, Benardos Nikolai Nikolaevic, who realized in 1881 that two metal pieces can be tightly joined together … Continue reading "Electric Arc Welding"
