Chapter 14: Science and Technology “We have arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces. ” —Carl Sagan, astronomer and astrobiologist
Science and Technology Introduction • Science – The process of discovering, explaining, and predicting natural or social phenomena. • Technology – Activities that apply the principles of science and mechanics to the solutions of a specific problem.
Science and Technology Introduction • Automation – Dominant in an industrial society, the replacement of human labor with machinery and equipment that is self-operating. • Mechanization – Dominant in an agricultural society, the use of tools to accomplish tasks previously done by hand. • Cybernation – Dominant in a postindustrial society; the use of machines to control other machines.
The Global Context: The Technological Revolution • The world is a much smaller place than it used to be, and it will become even smaller as the technological revolution continues. • In 2011, the Internet had 2. 1 billion users in more than 200 countries with 240 million users in the United States.
The Global Context: The Technological Revolution • The decline of U. S. supremacy in science and technology is likely to be the result of several interacting forces: – First, the federal government has been scaling back its investment in research and development. – Second, corporations, the largest contributors to research and development, have begun to focus on short-term products and higher profits as pressure from stockholders mounts.
The Global Context: The Technological Revolution • Decline of U. S. Supremacy Cont’d: – Third, developing countries, most notably China and India, are expanding their scientific and technological capabilities at a faster rate. – Fourth, there has been a drop in science and math education in U. S. schools, both in terms of quality and quantity. • STEM: An acronym for science technology, engineering and mathematics.
Sociological Theories of Science and Technology Structural-Functionalist Perspective • Science fulfills the need for an assumed objective measure of truth. • If society changes too rapidly, problems may emerge. • Cultural lag is a condition in which the material part of culture changes faster than the nonmaterial part.
Sociological Theories of Science and Technology Conflict Perspective • Technological advances are motivated by profit. • Funding of research is determined by dominant groups. • Science and technology also further the interests of dominant groups to the detriment of others. • Finally, conflict theorists as well as feminists argue that technology is an extension of the patriarchal nature of society that promotes the interests of men and ignores the needs and interests of women.
Sociological Theories of Science and Technology Symbolic Interactionist Perspective • Knowledge is relative, it changes over time and between societies. • Scientific “truths” are socially constructed and result from interactions between scientists, researchers, and the public. • Who becomes involved in what aspects of science and technology is socially defined.
Technology and the Transformation of Society Technology and the Workplace • Some technology lessens the need for supervisors and makes control by employers easier. • Technology can also make workers more accountable by gathering information about their performance. • Technology is also changing the location of work. – Telecommuting has increased as the result of several interacting social forces over time. – Telepresencing, a much more technologically sophisticated version of teleconferencing, allows lifesized participants in the virtual presence of one another to realistically communicate through broadcast quality sound and images.

Technology and the Transformation of Society Information and Communication Technology and the Internet • Politics and e-Government – Technology is changing the world of politics. In 2010, approximately 73 percent of U. S. adult Internet users went online to find news or information about the 2010 midterm elections, or to send or receive political messages through e-mail, instant messaging, Twitter, and the like.
Technology and the Transformation of Society Information and Communication Technology and the Internet • Social Networking and Blogging – Social network sites (e. g. , Facebook, Twitter) and blogs comprise a sector of the Internet called membership communities. Membership communities have changed in recent years in three substantively significant ways. 1. First, the number of people who visit membership communities has increased. In 2010, Facebook topped 500 million members around the world. 2. Second, the amount of time members spend at a membership community site has grown dramatically. 3. Finally, who joins membership communities is changing.
Technology and the Transformation of Society Science and Biotechnology • Genetics – Molecular biology has led to a greater understanding of the genetic material found in all cells, DNA, and with it the ability for genetic screening. – Gene therapy involves identifying defective or missing genes to get a healthy duplicate and transplant it to the affected cell. – Genetic engineering is the ability to manipulate and alter the genes of an organism.
Technology and the Transformation of Society Science and Biotechnology • Food and Biotechnology – Genetic engineering is the ability to manipulate the genes of an organism in such a way that the natural outcome is altered. – Genetically modified (GM) food, also known as genetically engineered food, and genetically modified organisms involve this process of DNA recombination —scientists transferring genes from one plant into the genetic code of another plant. – In the United States, genetically modified organisms (GMOs) are in an estimated 80 percent of all packaged food sold in the United States and Canada.
