How fast is technology is increasing?
At an exponential rate. What invention marks the beginning of the Renaissance? The Printing Press and Johann Gutenberg's movable type. What invention marks the beginning of the Industrial Age? James Watt's practical and more efficient steam engine. What invention marks the beginning of the Information Age? The programmable computer and the transistor.
Stone Age Approximately 250,000 B.C.- 3,000 B.C. During the Stone Age most tools were made of stone. Shaping rocks into sharp edges for arrows, spears, and knifes was very time consuming and the tools would easily wear with use. Most tools were used for agriculture and hunting. Bronze Age Approximately 3000 B.C. - 1200 B.C. Bronze is a metal alloy made of copper and tin. People found it easier to shape tools if metal was melted then shaped by using a mold. The metal tools were not only easier to shape, but were more durable and useful than stone tools. Most technological developments were for improved agriculture practices, growing industries and military applications. Iron Age Approximately 1200 B.C. - 500 A.D. Iron is metal, and when alloyed with other materials is stronger than bronze. Again, most technological developments were brought about to improve agriculture, trade and military weapons. Middle Ages Approximately 500 A.D. - 1500 A.D. The Middle Ages brought about a number of technological developments that led to industrialization. The agricultural advances produced a surplus of crops, which led to increased trade. Increased trade created bigger markets with more products. The spinning wheel was one of the jumpstarts of a growing textile industry. Renaissance Approximately 1450 A.D -1700 A. D. The Renaissance was a time of rebirth in the arts. Gutenberg invented the printing press with moveable type, which enabled information to be disseminated throughout the world. At first, the printing press was used for the distribution of the Bible, but as time progressed, it was used to produce other literature. Leonardo da Vinci created drawings and written descriptions of things that were later developed in the 20th Century. Industrial Age Approximately 1700 - 1940. The Industrial Age marks the point in history in which factories took over the production of most products. People began to buy items and migrate toward cities for jobs. The growing number of factories drove the need for technological improvements in machinery and systems. Trade over long distances increased which created a bigger demand for fast, reliable, efficient transportation systems. Communication advances accelerated information and coordination systems at an alarming rate. Structural systems were forced to improve as cities began to grow up instead of out. Information Age Approximately 1940 - present. The Information Age is a period of time where technological developments have and will continue to occur at an exponential rate. New developments are often outdated before the finished product arrives at the store for purchase. The microchip revolutionized the world of electronics and has made communication systems faster, cheaper, and more powerful than ever. Constant research occurs in energy systems to make them more efficient and less harmful to the environment. Manufacturing systems are highly technical and require specialized education. Structural systems are constantly changing to incorporate new materials and creative approaches to efficient building. According to the Standards for Technological Literacy, what is a trend? A trend is considered a tendency or general direction. Why might someone need to be technologically literate. In order to make better decisions about the world around them. Process for determining trends
What is a Technology Assessment? A Technology Assessment describes a variety of techniques for determining the effects of the interaction of technology and society. What is the purpose of a Technology Assessment? Because the impacts of technology profoundly affect people's lives, it is important to be able to identify desirable and undesirable consequences of technological decisions. What are two of the many techniques used to forecast paths of technological development? Normative forecasting and Exploratory forecasting Describe Normative Forecasting. Normative Forecasting helps people determine a path to take in the development of technology in order to arrive at an ultimate goal. Describe Exploratory Forecasting. Exploratory forecasting helps people look into the future by using past and present conditions to predict future events and developments. Exploratory forecasting involves identifying trends and extending them into the future. What is a Delphi Study? A Delphi Study is an example of an exploratory forecasting technique that depends on the professional opinions of experts in a given field. |

Where and in what year did the Television debut at the Worlds Fair & who was the President of the United Staes? What is the scientific name of the odd marsupial was brought to extinction as a result of hunting by sheep farmers by the beginning of the 20th century? If we have the ability to clone these animals that humans have forced to extinction, should we bring them back? Why or why not? In what year and why did Charles Lindburgh fly across the Atlantic Ocean to Europe? |
