Effects of Technological Developments Tradeoff A technique of reducing one or more desirable outcomes in exchange for increasing or increasing other desirable outcomes in order to maximize effectiveness under given circumstances.
Steel • Evidence of steel tools dates back 4,000 years • The alloy was not mass-produced until the invention of the Bessemer Process, a technique for creating steel using molten pig iron, in the 1850s. • Steel exploded into one of the biggest industries on the planet and was used in the creation of everything from bridges and railroads to skyscrapers and engines. • It proved particularly influential in North America, where massive iron ore deposits helped the United States become one of the world’s biggest economies.
The Telegraph • First in a long line of communications breakthroughs that later included radio, telephones and email. • The telegraph used Samuel Morse’s famous Morse code to convey messages by intermittently stopping the flow of electricity along communications wires. • Telegraph lines multiplied throughout the 1850s, and by 1902 transoceanic cables encircled the globe. • The ability to send messages rapidly across great distances made an indelible impact on government, trade, banking, industry, warfare and news media, and formed the bedrock of the information age.
