BakeliteBakelite enabled inexpensive mass production at very high tolerances where interchangeable parts matter (ex: telephones, radios, plugs, pens, wristbands, insulators, etc…). Also, it looked fun compared to organic materials in use before Bakelite. Baekeland’s Bakelite opened the “age of plastics.” It was moldable into any shape and, once molded, kept its shape. It did not … Continue reading "Bakelite"
Matches1827 Friction matches are ordinary matches. Strike them against a flint or, for some types, any hard service and they start a fire. Friction Matches were invented by Englishman John Walker in 1827. While it seems hard to believe it took so long before the innovation of matches by Walker people would have to find … Continue reading "Matches"
In-Vitro FertilizationIn-Vitro Fertilization (IVF) allows eggs to be fertilized outside the womb. In a controlled environment, fertilization is more likely to be successful. In 1936, In-Vitro Fertilization (IVF) was first performed on rabbits by Dr. Gregory Pincus of Harvard University. He announced his invention and mentioned it might someday work on humans. Rather than celebrate the … Continue reading "In-Vitro Fertilization"
JukeboxThe Jukebox is an automated coin-operated music player which plays individual songs. The differentiating factor of the Jukebox from a simple coin-operated record player is the ability of an automated machine to replace live music in a restaurant or bar. Background Louis Glass and William Arnold modified Edison’s record players to operate by coins. These … Continue reading "Jukebox"
SubmarineSubmarines changed naval warfare, increasing the risk of maritime travel from hostile countries. Underwater ships have existed in various forms for ages. There was a semi-underwater boat built for Tsar Peter the Great in 1720, and also one allegedly built during the US revolution in 1776. Steamboat baron Robert Fulton built one for the French … Continue reading "Submarine"
Birth Control Pill“The church has ever opposed the progress of woman on the ground that her freedom would lead to immorality. We ask the church to have more confidence in women.” Margaret Sanger, Co-Inventor of the Birth Control Pill & Founder, Planned Parenthood Birth Control pills have an especially colorful history. Development of The Pill involved four … Continue reading "Birth Control Pill"
Container ShippingBefore container shipping, trucks were manually unloaded by longshoremen, loaded onto ships, and the process repeated at the destination. This added enormous cost, slowed shipping times and increased the risk of breakage. Inspired by WWII standardization, McLean designed containers that fit directly on ships. His standardized containers and ships enable faster and less expensive loading … Continue reading "Container Shipping"
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)"
Electrical Transformer1831 Michael Faraday Faraday’s transformer acted as a knowledge bridge to future innovators that electricity could be transformed. It wasn’t especially useful on its own except to signal to future scientists what is possible. His transformer was vital to the creation of the modern electricity grid and electrical innovations. The device itself is hand-built by … Continue reading "Electrical Transformer"
FM RadioHistory In 1906, Lee de Forest invented the “three-electrode Audion” cathode ray tube. However, by his own admission, saw no use for it in radio. During his time at Columbia, Armstrong worked with Audion tubes and realized they could recycle a radio signal, amplifying it by sending it repeatedly through the tube. Further, by reversing … Continue reading "FM Radio"
PhonographWe, the editors of innowiki, have reviewed thousands of inventions. We’ve read through countless idea, rejecting the vast majority not because they lacked merit but because they didn’t rock the world. Background Of the innovations we accept there are very few who have more than one invention. Granted, the raw number of innovations does not … Continue reading "Phonograph"
Ballpoint PenBallpoint pens are modern pens, where ink a tube coats a ball at the end which writes. Unlike fountain pens they are inexpensive and require no skill beyond the ability to write. Loud, an American Harvard-educated lawyer, invented and patented the ballpoint pen but failed to commercialize the pen. Other versions were released but none … Continue reading "Ballpoint Pen"
Tractor Treads1904 Benjamin Holt “In the Roberts Island tract, where a man could not walk without sinking to his knees, and where tule-shoed horses could not be used, the new traction engine was operated without a perceptible impression in the ground.” Farm Implement News, May 18, 1905 “It looks like a caterpillar,” said a photographer observing … Continue reading "Tractor Treads"
Personal Portable Music PlayerBattery operated portable personal music players are fun, enabling users to build a cocoon of their own music. Portable radios and stereos date back to the invention of the transistor. Over time, these grew in size and power. Enormous stereos run from batteries, “boom boxes,” were commonplace. However, boom boxes played music from speakers and … Continue reading "Personal Portable Music Player"
Autonomous Vehicles (Self-Driving Cars)DARPA, the US government agency that invented the internet (among other things) created a contest to build a self-driving car. The first DARPA Grand Challenge, in 2004, was a 150 mile (240 km. route). The robot-car that drove the furthest before breaking down, built by Carnegie-Mellon University (CMU), lasted 11.78km. Undeterred, DARPA tried again. Subsequently, … Continue reading "Autonomous Vehicles (Self-Driving Cars)"
