Intrauterine Device (IUD)Intrauterine Devices (IUD’s) are long-lasting passive birth control for women. Once inserted they work anywhere from ten years to life. IUD’s are the most common birth-control method in the world. Background IUD’s were first developed in 1909 by Richard Richter of Waldenburg, Germany. Ernst Gräfenberg also supported the devices. He is the doctor the “G-Spot” … Continue reading "Intrauterine Device (IUD)"

Wi-FiIn 1941, Hollywood actress Hedy Lamarr devised a system and submitted a patent for radio signals that changed frequencies. Background Hedwig Eva Maria Kiesler (Heidi Lamar) was born in Vienna. She is most famous as the first woman to appear nude in a mainstream film. In the same movie, she was also the first woman … Continue reading "Wi-Fi"
Surgical AnesthesiaAnesthesia enables modern surgery, reducing pain and risk. Before anesthesia, patients were held down and surgeons would have to operate quickly. Amputations were common because surgeons did not have the time to do more complicated work before a patient went into shock from the pain. Ether is the first anesthesia. William Morton, a dentist, is … Continue reading "Surgical Anesthesia"
Musical Instrument Digital Interface (MIDI)MIDI allows instruments to talk to computers and to one another. As engineers began connecting instruments to computers it became clear there needed to be a standard interface so that each instrument did not need to “talk” differently to each computer. Smith, who holds degrees in computer science and electrical engineering. He created the MIDI … Continue reading "Musical Instrument Digital Interface (MIDI)"
Credit CardMerchants have always issued credit in one form or another directly to customers. But the idea that a bank would issue credit to purchase anything then, eventually, collect from their customer is newer. In 1946, after WWII, John C. Biggins invented the first universal credit card, called “Charg-It.” However, the card only worked at participating … Continue reading "Credit Card"
PasteurizationFrench scientist Louis Pasteur disproved the theory of spontaneous generation, the idea that certain organisms are ever-present in nature. For example, early scientists believed fleas came from dust and maggots from dead meat absent anything else. Pasteur theorized and later proved that all organisms come from something else, that nothing exists in a vacuum. He … Continue reading "Pasteurization"
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)"
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"
Blockchain Explained? Hype or Hope?Blockchain is like the gluten diet a few years back; everybody’s into it but nobody’s quite sure why and few people really need it though to those who do it’s important. I’ll analyze it through the only metric that really matters, value. But before doing that, we need to understand what the it actually is. … Continue reading "Blockchain Explained? Hype or Hope?"
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)"
Relational Database Management System (RDBMS)Relational databases simplify the storage and retrieval of related information. For example, rather than storing the state a person lives in a relational database might store a number to a single list of all states. Significantly, this reduces overall storage needs and makes indexing and searching significantly easier and subsequently faster. Edgar Codd, working at … Continue reading "Relational Database Management System (RDBMS)"
Facsimile (FAX) MachineAlexander Bain created a telegraph that transmitted light and dark dots that were reproduced on the other side, the fax machine, long before the telephone. Early faxes were popular with newspapers due to their ability to quickly transmit crude images. Countless modifications and improvements followed over the years. Despite the obvious differences in the innovation, … Continue reading "Facsimile (FAX) Machine"
Photocopiers“Xerography was an invention we didn’t know we needed until, suddenly, we didn’t know how we lived without it.” Carlson biographer David Owen Chester Carlson Chester Carlson had a childhood nobody would want to copy. His father was perennially ill and poor. Mom, dad, and young Chester lived in a leaky hut in Mexico until … Continue reading "Photocopiers"
Modern Computer Programming LanguagesEarly computers were programmed by literally connecting wires then turning the machine on. Eventually, that evolved to assembly language; a one and zero type exercise telling the computer exactly what to do. Modern computer programming languages are more like English. Programmers write in an English-like language and a computer program turns that into the ones … Continue reading "Modern Computer Programming Languages"
