One day in 1991 at Cambridge University, a researcher needed a cup of coffee. Battling eyestrain and foggy brain (one imagines), he trudged down the hall, up the stairs, around the corner, up another flight of stairs, and on and on to the coffeemaker that was stationed in the corridor outside the computer lab’s Trojan Room. Alas, the so-called Trojan coffeepot was empty.The book is a mixture of erudite etymology, strange connections between words, odd humour and even challenge questions, 'make a cocktail, write the ingredients in the margin'. It's good but I wish it was either less light humour and more solid etymology, or conversely, light and humorous perhaps the linguistic equivalent of Mary Roach and her popscience books.
To guard against caffeine disappointment in the future, a couple of plucky researchers thought up a plan. They focused a camera on the pot and connected the feed to a video frame grabber in the Trojan Room, then created a program that allowed researchers to see a frequently updated image of the coffeepot. No more wasted to-ing and fro-ing to check on the coffee supply. Thus, the serendipitous but nevertheless spectacular invention of what eventually became the webcam, now used by zillions of Zoomers, FaceTimers, and other lookers every day.
The live feed remained active for a decade, and the coffeepot became so famous that when it was retired, it sold on eBay for thousands of pounds. The coffeepot is now living out its retirement in a German museum.
