This booklet is designed to make revision faster by bringing together the topics that repeatedly matter in the exam. Instead of reading multiple bulky sources, you get crisp explanations, diagrams, fact boxes, and exam-oriented notes that help you revise important concepts within a limited time. Whether you are starting your preparation or doing the final revision before Prelims, this book helps you identify high-priority areas and build confidence. The UDAAN Prelims Wallah (Static) Science & Technology booklet by PW OnlyIAS follows a revision-first approach. It focuses on concepts that are frequently tested in UPSC Civil Services Preliminary Examination while keeping the language simple enough for beginners. The content is arranged in a structured sequence so that readers can move from basic scientific concepts to advanced applications without feeling overwhelmed. The booklet is also designed to complement standard reference books rather than replace them, making it especially useful during revision. The UDAAN series integrates concise notes with previous year question references and exam-focused presentation to improve retention. The Science & Technology booklet generally covers important themes such as the basics of Physics, Chemistry and Biology relevant for UPSC, biotechnology, genetics, DNA and genome technology, vaccines, immunology, human diseases, space technology, Indian space missions, satellites, astronomy, nuclear technology, defence technology, robotics, artificial intelligence, machine learning, quantum technology, nanotechnology, semiconductor technology, information technology, communication systems, cyber security, blockchain, cloud computing, internet technologies, renewable energy, hydrogen energy, battery technology, environmental technologies, scientific institutions of India, Nobel Prize related concepts, important discoveries, scientific organisations, and other emerging technologies that frequently appear in the examination. Concepts are presented with definitions, flowcharts, tables, and concise explanations so that revision becomes quicker and more effective. The booklet also aligns its coverage with the changing trend of UPSC questions, where conceptual understanding is more important than memorising isolated facts. This book is mainly meant for UPSC Civil Services Preliminary Examination aspirants. However, the conceptual clarity offered by the booklet also makes it useful for candidates preparing for State PSC examinations, CAPF Assistant Commandant, CDS, NDA General Studies, EPFO, and other competitive examinations that include General Science or Science & Technology sections. Students appearing for SSC CGL, SSC CHSL, SSC MTS, RRB NTPC, RRB Group D, Banking examinations, Insurance examinations, and similar recruitment tests may also find selected chapters useful for strengthening their general awareness, although the primary focus remains UPSC.
