Induction Motors“Intelligent people tend to have less friends than the average person.” Nikola Tesla There are two types of electricity, Direct Current (AC) and Alternating Current (AC). Vastly simplifying, in DC electrical systems the current flows in one direction, like current in a stream. This makes designing certain appliances easier; the motor turns in the direction … Continue reading "Induction Motors"
Micro-Electro-Mechanical Systems (MEMS)MEMS are literally microscopic-machines. The best-known MEMS are the accelerometers that have become ubiquitous in smartphones, allowing precise tracking of movement on the X, Y, and Z-axis. Significantly, MEMS are the reason your phone can sense movement. Additionally, other MEMS devices include miniature microphones, projectors, cameras, and countless others. MEMS were first proposed in 1959 … Continue reading "Micro-Electro-Mechanical Systems (MEMS)"
Game TheoryGame theory serves as the foundation of systematized decisionmaking and modern economics. Indeed, Minimax game theory underlies modern economics and is responsible for countless economic insights, many of which won Nobel Prizes. Besides game theory, von Neumann eventually modeled the lenses behind the Los Alamos plutonium nuclear bomb. As a Jewish refugee from Europe whose … Continue reading "Game Theory"
Catalytic ConverterCatalytic converters prevent knocking in engines without leaded fuel. Houdry was a Frenchman working on high-octane fuels. His initial focus were race cars. Sun Oil sponsored the early work, in the 1930’s, moving Houdry to the US. The fuel work was a success but could not be use in mass production because the catalysts that … Continue reading "Catalytic Converter"
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"
Lithium-Ion BatteryLithium-Ion Batteries (LIBs) power everything from smartphones to power tools and electric cars. Entire cities store power generated during the day, via solar panels, for use at night from large lithium battery arrays. One of the largest factories in the world, the Tesla Gigafactory, is devoted solely to manufacturing Lithium-Ion batteries. Background An ability to … Continue reading "Lithium-Ion Battery"
Polio VaccineAppearing out of nowhere in the late 1900s, polio terrified American communities in the early 20th century. 1 in 200 infections led to irreversible paralysis. Of those, 5-10% died from breathing paralysis. Iron lungs that breathed for polio sufferers also trapped them. The virus paralyzed President Roosevelt. No sooner did the virus appear than entire … Continue reading "Polio Vaccine"
Jet EngineAn RAF pilot he thought up the jet engine and tried convincing the English military to fund development. When they refused, he created a private company to develop his jet engine, Power Jets Ltd. Undercapitalized, development of the new engine plodding along slowly. During WWII, the Allied forces realized the military potential of the jet … Continue reading "Jet Engine"
- 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"
Aspirin1899 Arthur EichengrünFelix Hoffman Aspirin is often referred to as a miracle drug. The inexpensive medicine relieves pain without addiction, reduces fever, and even helps prevent heart attack. There is some evidence Aspirin even prevents cancer. Aspirin is the distilled and purified version of medicine known since ancient times. Hippocrates, he of the Hippocratic Oath, … Continue reading "Aspirin"
Alternators / Long-Distance Transmission of ElectricityAlternators and Alternating Current enabled the long-distance transmission of electricity. Edison’s electrical plant ran on DC which does not transmit far. Under Edison’s system, there were electric plants every few blocks in cities (the inner Chicago loop had 25 electric plants at one point). Tesla’s AC system transmitted electricity much further; it’s the same we … Continue reading "Alternators / Long-Distance Transmission of Electricity"
Shareholder Value Theory: Milton Friedman ReduxOn September 13, 1970, Milton Friedman published one of the most arguably economically destructive articles in history, “The Social Responsibility Of Business Is to Increase Its Profits,” in the New York Times. The article is available, in PDF form, for subscribers from the New York Times website. Friedman advanced the idea that managers are agents … Continue reading "Shareholder Value Theory: Milton Friedman Redux"
Antibiotics“I did not invent penicillin. Nature did that. I only discovered it by accident.” Sir Dr. Alexander Fleming Few medical discoveries impacted life expectancy and quality of life more than antibiotics. Before their discovery, simple wounds were often fatal. For example, during the US Civil War, most soldiers eventually died from infection, not from their … Continue reading "Antibiotics"
AirlineCount von Zeppelin, inventor of the airship, partnered with a group of other German industrialists to create a Zeppelin manufacturing company and also an airline. Airships Their first airship, the enormous LZ1, launched July 2, 1900. It crashed and survived but the test was not successful for the German government to invest more funds in … Continue reading "Airline"
Kodak Brownie“You press the button, we do the rest” announced Kodak introducing the camera their first mass market camera. In May 1888, George Eastman invented and sold a camera packed with film for 100 photographs. Customers snapped their hundred photos then mailed the camera back to Kodak. Kodak mailed back the prints and the camera reloaded … Continue reading "Kodak Brownie"
