Blue JeansBlue jeans are fun. The once entirely functional pants evolved to represent a lifestyle. When sold as functional work pants, Levi’s did OK. When sold on emotion sales mushroomed. Background Levi Loeb immigrated from Germany to the US and changed his name to Strauss, which sounded more American. In Germany, Jews were forbidden from owning … Continue reading "Blue Jeans"
Roll Film & Roll Film CameraKodak’s original camera contained plates. Later versions contained one-hundred exposures; customers would take their pictures, mail in their camera, and the company mailed back developed pictures and a refilled camera. Roll film changed all that, vastly lowering the cost and complexity of photography and eventually enabling the creation of movie film. Ordinary people could purchase … Continue reading "Roll Film & Roll Film Camera"
MicrocomputerThe first microcomputer, the Altair 8800, was like a French bulldog. That is, it was ugly, expensive, and not all that bright, but people loved it. The Altair didn’t even have a display, just LED’s that lit up. Most significantly, it served as the inspiration for a small number of future computer entrepreneurs. The cover … Continue reading "Microcomputer"
Why not Wikipedia? Deletionists.There is a major problem with Wikipedia, deletionists. Deletionists, as the name suggests, get off on deleting things. They tear down rather than build up. Why would they want to do this? There are two primary reasons. First, it is an easy way to increase the number of Wikipedia edits which increases the visibility and … Continue reading "Why not Wikipedia? Deletionists."
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"
Electrical Generator (Dynamo)1831 Michael FaradayJoseph Henry No one person “discovered” electricity. The story about Ben Franklin flying a kite with a key in a thunderstorm and discovering electricity when the kite was struck by lightning is especially ridiculous. A Russian apparently tried the same experiment soon after reading about it and was electrocuted. Alessandro Volta, who invented … Continue reading "Electrical Generator (Dynamo)"
HelicopterIgor Sikorsky was a Russian aircraft designer. He created various aircraft for the Russian army, including early helicopters. No sooner did the Bolshevick’s take over than Sikorsky fled to the US after the Russian Revolution in 1919. In the US, he created a business, Sikorsky Aircraft Corporation, designing aircraft. His first American airplane was a … Continue reading "Helicopter"
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"
Magnetic Resonance Imaging (MRI)MRI allows physicians to see and diagnose soft tissue without surgery. Background MRI is one of these cases where everybody argues somebody else invented it for patent priority. However, courts and historians find that physician Raymond Damadian was first to make an MRI that scans people (prior MRI’s would scan small pieces of organic material). … Continue reading "Magnetic Resonance Imaging (MRI)"
Clusters of Regularly Interspaced Short Palindromic Repeats (CRISPR)CRISPR is like a word processor for DNA. It allows easy and inexpensive gene editing. Edited genes are passed to future generations, making mutations permanent. Doudna and Charpentier Doudna and Charpentier worked on and invented the technology as a team. First, they worked on plants and, later, on animals. History becomes murkier with the involvement … Continue reading "Clusters of Regularly Interspaced Short Palindromic Repeats (CRISPR)"
Electronic Stock Exchange (NASDAQ)History In early stock markets, traders offered and accepted bids for stock prices to one another. People would stand in a stock exchange and literally yell out stock symbols and prices. Buyers would purchase blocks of stock. This system was slow and expensive. Only high-level bankers had access to the people on a stock trading … Continue reading "Electronic Stock Exchange (NASDAQ)"
Franchising & Cross-MarketingBefore McDonald’s King Ray Kroc was born Martha Harper built an enormous franchise empire. At a time few women worked in business, much less founded and owned them, she developed two vital strategic moves. Harper created cross-marketing, the concept where that stores with one purpose can sell related products. Specifically, she created hair salons to … Continue reading "Franchising & Cross-Marketing"
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"
Object-Oriented ProgrammingObject oriented programming is the first of countless Xerox PARC inventions. Vastly simplifying, there are two ways to program a computer. In procedural programming, each thing the computer does is listed. Conditional statements tell the computer which path to follow. Comparatively, in object-oriented programming, objects mimic real life. Programmers then act on these objects. For … Continue reading "Object-Oriented Programming"
Polymerase Chain Reaction (PCR)Polymerase Chain Reaction (PCR) turns a tiny bit of DNA into a much larger amount which can subsequently be sequenced. In 1983, Mullis figured out a way to multiply the tiniest piece of DNA by orders of magnitude, making millions of copies. This is how the smallest bit of DNA, from bacteria, viruses, historical artifacts, … Continue reading "Polymerase Chain Reaction (PCR)"
