DUCT TAPE (1942) There is a truth behind any jest, and you have all heard the saying that one can fix any problem as long as you have duct tape. There cannot be a household in the universe that has not at one time or the other turned to this magical roll of ugly, sticky grey tape to fix a problem. Yet, duct tape first started out in military green colours during World War II, when Johnson & Johnson’s Revolite Permacell division developed the multi-purpose tape known for its ease of use, durability and waterresistance. It was used to seal containers and fix windows and equipment during the war. Post-war, duct tape got its boost from the construction industry. Much of success in business depends on the ability to spot arbitrage moments. To see gaps where others miss it, and to come up with cost effective ways of servicing that gap for profit. GPS (EST 1959) If you have to lob bombs and missiles over long distances and into areas that you cannot see, geographical accuracy becomes a kind of necessity. But first, the US Navy and Air Force developed this system in order to be able to navigate better. As satellite technology improved, and the triangulation of positions anywhere around the globe became increasingly possible with more and better satellite signals, the sophistication of these systems also improved. Today, you can locate your Aunt Betty’s flat in Kempton Park’s old age home when you combine your GPS and some of the modern mapping systems. And, it is also possible for us to know where you are! Next big thing – tracking your teenage kids through the GPS positioning of their cellphones. No more sneaking off to parties pretending to be busy with homework at a sleepover. MICROWAVES (1945) Its use for food preparation was accidental. A Raytheon employee, working on military contracts, realised that the chocolate bar in his pocket had melted. That opened up a new universe for the magnetron, originally the result of research conducted on radio transmission and radar detection. The magnetron produced much smaller radio waves, known as microwaves, and was small and powerful enough to be used in airplanes. Its detection capabilities helped solve the persistent problem of accurately bombing towns. In 1954, the first microwave oven came to market. 35
