Advanced technology" redirects here. For the Advanced Technology form factor, see AT
By the mid 20th century, humans had achieved a mastery of technology sufficient to leave the atmosphere of the Earth for the first time and explore space.Technology deals with human as well as other animal species' usage and knowledge of tools and crafts, and how it affects a species' ability to control and adapt to its natural environment. The word technology comes from the Greek technología the study of something, or the branch of knowledge of a discipline.[1] A strict definition is elusive; technology can be material objects of use to humanity, such as machines, but can also encompass broader themes, including systems, methods of organization, and techniques. The term can either be applied generally or to specific areas: examples include "construction technology", "medical technology", or "state-of-the-art technology".
