Instant MessagingSending instant messages by computer is fun and convenient. Moreover, text chatting is asynchronous, unlike voice or video. Accordingly, people need not communicate in real-time. Surprisingly, text messaging became extremely popular. The earliest instant messaging system designed for that purpose was “Talkomatic” and “term-talk” for the PLATO system. College students David Wooley and Doug Brown … Continue reading "Instant Messaging"
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"
Water Frame Spinner / Modern FactoryRichard Arkwright’s Water Frame Spinner created factories that did not require highly skilled labor. Women and children, with no training, worked in factories that churned out low-cost good enough quality fabric at high volumes. This vastly lowered the cost of fabric. Arkwright was from a poor family: his father was a tailor. He improved on … Continue reading "Water Frame Spinner / Modern Factory"
Personal Computer, Xerox Alto (the “interim Dynabook”)Dynabook was at the heart of Xerox PARC. Eventually realized as the Xerox Alto, it is essentially the first personal computer. Easy-to-use with a graphical interface, what-you-see-is-what-you-get (WYSISYG) programs, icons, the mouse, networking. Everything we take for granted today started as the Dynabook/Alto. Background The Dynabook dates to Kay’s doctoral thesis and the first interview … Continue reading "Personal Computer, Xerox Alto (the “interim Dynabook”)"

Synthetic Drugs via Genetic Manipulation (Biotech)Synthetic hormones via genetic manipulation allow for new and improved drugs. For example, insulin that remains stable at room temperature, growth hormones grown in a vat instead of harvested from cadavers, and countless others. Background Herbert Boyer was a scientist working on synthesizing DNA, one of many. Robert Swanson was a venture capitalist. He left … Continue reading "Synthetic Drugs via Genetic Manipulation (Biotech)"
Tetraethyllead (Leaded Gasoline)Leaded gasoline prevented engine ping, making driving safer and more pleasant. Correspondingly, it also caused an enormous amount of extremely toxic pollution. Working for GM under the direct supervision of Charles Kettering at Dayton Research Laboratory, Midgley discovered the benefits of adding lead to gasoline. They named their innovation Tetraethyllead, avoiding any mention of lead, … Continue reading "Tetraethyllead (Leaded Gasoline)"

Ironclad ships reduced the cost and risk of shipping by enabling larger ships that were more difficult to sink. The first known ironclad warship was The Nemesis, built for the East India Company, in 1839. Soon, … Continue reading "Steel Ships"
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"
Is there a source of Newcomen engine models for sale anymore? I have a future event/opportunity to explain and educate students about early steam. There used to be working tabletop models from the UK available for about $250 US, perhaps 8 to 12 years ago.
I’d suggest trying the Trevithick Society of England – they may know where to find something like that. http://www.trevithicksociety.info/
