Description
Science and Technology is no longer just a chapter in the UPSC syllabus—it is the engine driving India’s governance, economy, defence, health, climate strategy, and global standing. From ISRO’s satellite launches to DRDO’s strategic systems… from India’s AI and semiconductor missions to breakthroughs in biotechnology, vaccines, and quantum technologies—S&T shapes every major decision of the government today. UPSC expects you to understand these technologies as they work in the real world and connect them with governance, public policy, and international developments.
These notes have been created to help you do exactly that.
Every concept—AI-ML, robotics, ICT, 5G-6G, cybersecurity, biotechnology, gene editing, vaccines, nanotech, quantum communication, nuclear energy, space tech, renewable energy, supercomputing, climate tech—has been explained in simple, logical language.
