: Overview & Introduction
Definition
General Science refers to the systematic study of the natural world through observation, experimentation, and theoretical modeling, encompassing disciplines such as physics, chemistry, biology, earth sciences, and emerging interdisciplinary fields like nanotechnology, quantum information, and artificial intelligence. In the context of competitive examinations, it also includes awareness of recent scientific breakthroughs, technological applications, and India’s contributions to global S&T.
Historical Background
Since independence, India has pursued a self‑reliant S&T trajectory anchored by institutions like the Indian Institute of Science (IISc), Defence Research and Development Organisation (DRDO), Indian Space Research Organisation (ISRO), Council of Scientific and Industrial Research (CSIR), and Department of Biotechnology (DBT). Early milestones—such as the establishment of the Atomic Energy Commission (1948), the Green Revolution (1960s), and the launch of Aryabhata (1975)—laid the foundation for today’s achievement‑driven ecosystem. The 21st century has witnessed a shift from incremental advances to disruptive innovations, supported by policy initiatives like the Science, Technology and Innovation Policy (STIP) 2013, the National Mission on Interdisciplinary Cyber‑Physical Systems (NM-ICPS) 2018, and the Anusandhan National Research Foundation (ANRF) 2023.
