Science & Technology
for Judiciary
Eight chapter notes covering science and technology as tested in state judiciary general knowledge papers — basic physics and chemistry concepts, biology and human health, India’s space programme (ISRO, missions), India’s defence technology (DRDO, missiles), information technology and cybersecurity basics, and environmental science with constitutional and legal dimensions. Concept first, institution second, legal dimension third.
Science for judiciary — with a legal and constitutional lens.
Science and Technology is tested in the General Knowledge paper of most State Judiciary examinations. The testing pattern favours applied and institutional questions over theoretical ones — the examiner tests knowledge of India’s space missions, defence programmes, and digital initiatives alongside basic science concepts. The judiciary-specific lens on science focuses on the legal dimensions — the IT Act, environmental protection legislation, drug regulation, and the legal framework for biotechnology.
These notes anchor every chapter to its science or technology topic and its exam relevance. The most-tested areas are India’s space programme (ISRO, Chandrayaan, Mangalyaan, PSLV, GSLV), India’s defence technology (DRDO, Agni and Prithvi missile series, INS Vikrant), information technology basics and cybercrime, environmental science (climate change, renewable energy, pollution), and the interface between science and law.
Each chapter is designed to be read in twelve to fifteen minutes and to leave the reader with the science or technology concept, the Indian institutional framework, the legal dimension where applicable, and the likely exam question types.
How to read these notes
Start with the institution.
Every science and technology chapter begins with the institutional anchor. Space: ISRO (Indian Space Research Organisation). Defence technology: DRDO (Defence Research and Development Organisation). Nuclear: DAE (Department of Atomic Energy) and the Atomic Energy Commission. Environment: MoEFCC (Ministry of Environment, Forest and Climate Change) and CPCB. Biotechnology: DBT (Department of Biotechnology).
Link to the legal dimension.
Every science topic has a legal dimension that is the judiciary examiner’s preferred territory. Cyber technology — IT Act. Environment — EPA 1986, Air Act, Water Act. Drugs — Drugs and Cosmetics Act 1940, NDPS Act. Food safety — FSSAI and the Food Safety and Standards Act 2006. Biotechnology — Biological Diversity Act 2002. The legal hook converts a GK question into a law question.
Test on the leading case.
If you can restate the holding of ISRO missions, DRDO programmes, IT Act and cybercrime, environmental law statutes, and science-law interface PYQ patterns in state judiciary GK papers in two sentences, you understand the chapter. If not, return to the statutory section and rebuild from there.
All 8 chapters, in 3 groups
Sequenced through the natural structure of the subject — every chapter sits in a doctrinal cluster.Basic Science & Human Health
Physics, Chemistry, Biology basics
Physics basics tested in judiciary GK — Newton’s laws, light and optics, electricity, sound. Chemistry basics — periodic table essentials, acids and bases, metals and non-metals, important compounds. Biology basics — cell biology, human organ systems, genetics and DNA, diseases and pathogens. Human health — vitamins and deficiencies, vaccines, communicable and non-communicable diseases. Drugs and the NDPS-Drugs and Cosmetics interface.
India’s Space & Defence Technology
ISRO, DRDO, and key programmes
ISRO — history, major launch vehicles (PSLV, GSLV, LVM-3), major missions (Chandrayaan 1/2/3, Mangalyaan, Aditya L1, Gaganyaan programme). DRDO — missile systems (Agni series, Prithvi, BrahMos), defence platforms (INS Vikrant, Tejas). India’s nuclear programme — the three-stage nuclear programme, the Atomic Energy Act, the nuclear doctrine. India’s satellite navigation system — NavIC.
IT, Environment & Science-Law Interface
Cybercrime, environment, legal hooks
Information technology basics — internet, cybercrime categories, IT Act 2000 offences (Sections 65 to 67B), Section 66A struck down in Shreya Singhal, cyber security frameworks. Environmental science — climate change and the Paris Agreement, renewable energy, air and water pollution, biodiversity. Environmental law interface — Environment Protection Act 1986, the Precautionary Principle, the Polluter Pays Principle, the National Green Tribunal. DNA evidence and the Evidence Act. Narco-analysis and the Selvi decision.
