In this context, it is the current state of humanity's knowledge of how to combine resources to produce desired products, to solve problems, fulfill needs, or satisfy wants; it includes technical methods, skills, processes, techniques, tools and raw materials. This new-found knowledge may then be used by engineers to create new tools and machines, such as semiconductors, computers, and other forms of advanced technology. For example, science might study the flow of electrons in electrical conductors, by using already-existing tools and knowledge. Various implementations of technology influence the values of a society,and new technology often raises new ethical questions. Additionally, technology is the application of math, science, and the arts for the benefit of life as it is known. As the Paleolithic era progressed, dwellings became more sophisticated and more elaborate; as early as 380,000 B.C.E., humans were constructing temporary wood huts.[20][21] Clothing, adapted from the fur and hides of hunted animals, helped humanity expand into colder regions; humans began to migrate out of Africa by 200,000 B.C.E. This flaking produced a sharp edge on the core stone as well as on the flakes, either of which could be used as tools, primarily in the form of choppers or scrapers. Science is the reasoned investigation or study of phenomena, aimed at discovering enduring principles among elements of the phenomenal world by employing formal techniques such as the scientific method.[7] Technologies are not usually exclusively products of science, because they have to satisfy requirements such as utility, usability and safety.
Engineering is the goal-oriented process of designing and making tools and systems to exploit natural phenomena for practical human means, often (but not always) using results and techniques from science. It is a far-reaching term that may include simple tools, such as a crowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons.

The use of tools by early humans was partly a process of discovery, partly of evolution. In human society, it is a consequence of science and engineering, although several technological advances predate the two concepts. The development of technology may draw upon many fields of knowledge, including scientific, engineering, mathematical, linguistic, and historical knowledge, to achieve some practical result.
Technology is often a consequence of science and engineering — although technology as a human activity precedes the two fields. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact on a global scale. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms.
Definition and usage
The invention of the printing press made it possible for scientists and politicians to communicate their ideas with ease, leading to the Age of Enlightenment; an example of technology as a cultural force.
In general, technology is the relationship that society has with its tools and crafts, and to what extent society can control its environment. The term can either be applied generally or to specific areas: examples include "construction technology," "medical technology," or "state-of-the-art technology."
Technology has affected society and its surroundings in a number of ways. In this sense, scientists and engineers may both be considered technologists; the three fields are often considered as one for the purposes of research and reference.[8]
Role in human history
The human race's use of technology began with the conversion of natural resources into
