INTRODUCTION TO SCIENCE Science is the effort to discover, and increasehuman understanding of how the Physical worldworks. Through controlled methods, scientistsuse observable physical evidence of naturalphenomena to collect data, and analyze thisinformation to explain what and how thingswork. Such methods include experimentationthat tries to simulate natural phenomena undercontrolled conditions and thought experiments.Knowledge in science is gained throughresearch.
INTRODUCTION TO TECHNOLOGY Technology is a broad concept that deals with a speciesusage and knowledge of tools and crafts, and how it affectsa species ability to control and adapt to its environment. Inhuman society, it is a consequence of science andengineering, although several technological advancespredate the two concepts. The word "technology" can also be used to refer to acollection of techniques. In this context, it is the currentstate of humanitys knowledge of how to combineresources to produce desired products, to solve problems,fulfill needs, or satisfy wants; it includes technical methods,skills, processes, techniques, tools and raw materials. Whencombined with another term, such as "medical technology"or "space technology", it refers to the state of therespective fields knowledge and tools. "State-of-the-arttechnology" refers to the high technology available tohumanity in any field.
Science and technology has been in the forefront of transformingthe Indian economic structure helping India evolve as a globallycompetitive economic powerhouse. With the available scientificmanpower--which is third largest in the world-- the Indianscience and technology has been growing well above worldaverage. While the Indian output of science, as measured by the qualityand quantity of Science Citation Index (SCI) papers, has beengrowing at a CAGR of 8 per cent in the past three years, the worldaverage was only 4 per cent. Also, the number of technicalworkforce is also increasing at a rapid clip and is set to cross the 2million mark, with the march from one million to two millionhappening in just about three years. Space Technology India is one of the few countries with expertise to conceptualize,design and manufacture satellites and the capability to launchthem into space. In fact, it has the largest constellation of remotesensing satellites in the world. Also, the Indian Space ResearchOrganisation (ISRO) is the worlds third non-US supplier of 1-metre imageries and holds nearly 25 per cent of the US$ 120-million global free-play imageries market
