Applied Sciences & IPR
🎯 PYQs — Applied Sciences (High Frequency)
Most Asked Topics:
- Standard Model of Particle Physics
- Higgs Boson vs Neutrinos
- Dark Matter vs Dark Energy
- Intellectual Property Rights (Patents, GIs, Ever-greening)
Common Traps:
- ❌ Neutrinos are NOT the God Particle (Higgs Boson is)
- ❌ Dark Matter absorbs light (No, it's invisible/non-interactive)
- ❌ Section 3(d) of the Patent Act allows ever-greening (No, it specifically prevents it)
- ❌ Copyright lasts forever (No, it lasts 60 years after the author's death)
1. Particle Physics
Standard Model & Fundamental Forces
| What are fundamental particles, and what are quarks and leptons? | Fundamental Particles: Elementary particles that cannot be divided further. Divided into: - Quarks: 6 types (Up, Down, Charm, Strange, Top, Bottom). They clump to form Hadrons (like Protons/Neutrons). - Leptons: 6 types (Electron, Muon, Tau, and their corresponding Neutrinos). - Bosons: Force-carrying particles. |
| Name the four fundamental forces of nature and their force-carrying bosons. | -
|
Elementary Particles: Higgs & Neutrinos
| Explain the Higgs Boson: function, mass, and spin properties. | - Higgs Boson (God Particle): Function: Confers mass on other fundamental particles via interaction with the Higgs Field. Properties: Mass of ~125 GeV; Spin 0 (the only elementary particle with no spin). |
| What are Neutrinos, and where is India's proposed observatory? | - Neutrinos (Ghost Particles): Properties: No electric charge, negligible mass, travel near the speed of light. They pass through matter with almost no interaction. Observatories: IceCube (South Pole); proposed India-based Neutrino Observatory (INO) in Theni, Tamil Nadu. |
CERN & The Large Hadron Collider (LHC)
| What is CERN, and identify key LHC detectors. | - CERN: European Organization for Nuclear Research (Geneva). India is an Associate Member. LHC (Large Hadron Collider): World's largest particle accelerator (27km ring). Detectors: ATLAS and CMS (discovered the Higgs Boson in 2012), ALICE, LHCb. |
2. The Universe & Cosmological Matter
Dark Matter vs Dark Energy
| Compare Dark Matter and Dark Energy: functions, proportions, and detection. | - Dark Matter: Acts as a gravitational "glue" pulling cosmic structures together. Accounts for ~27% of the Universe. Inferred via gravitational lensing. Experimentally detected using the LZ Experiment. Dark Energy: Repulsive force driving the accelerated expansion of the universe (antigravity). Accounts for ~68% of the Universe. Discovered via Type Ia Supernovae observations. |
Antimatter
| Define antimatter and explain the annihilation process. | - Antimatter: Subatomic particles with the same mass as ordinary matter but opposite electrical charge (e.g., Positron is the anti-electron). Annihilation: When matter and antimatter collide, they destroy each other, releasing pure energy. The heaviest antimatter nucleus observed is Anti-hyperhydrogen-4. |
3. Deep Ocean & Environmental Sciences
Deep Ocean Mission & Samudrayaan
| Explain Matsya-6000: crew capacity, depth limit, endurance, and target resources. | - Matsya-6000: India's first self-propelled manned scientific submersible under the Deep Ocean Mission. Specifications: Carries 3 humans to a depth of 6,000 meters. Endurance is 12 hours (normal) / 96 hours (emergency). Objective: Map and explore resources like Polymetallic Nodules (containing manganese, nickel, cobalt, and copper) in the Central Indian Ocean Basin. India is the 6th nation to possess this capability. |
Desalination Technologies
| Compare LTTD and Reverse Osmosis (RO) desalination technologies with Indian examples. | - LTTD (Low Temperature Thermal Desalination): Uses the temperature gradient between warm surface seawater and cold deep-sea water to evaporate and condense water. Implemented by NIOT in Lakshadweep. RO (Reverse Osmosis): Uses high pressure to force water through a semi-permeable membrane, rejecting salts. South Asia's largest RO plant is located at Nemmeli, Tamil Nadu. |
4. Intellectual Property Rights (IPR)
Patents: Protecting Inventions
| What is a Patent, its term, and the eligibility criteria? | - Patent: Exclusive right granted for an invention. Valid for 20 years from filing. Criteria: Novelty, Inventive step (non-obviousness), and Industrial application. |
| Explain Section 3(d) of the Indian Patent Act and ever-greening. | - Ever-greening: Extending the patent life of a drug by making minor, non-therapeutic changes. Section 3(d): Specifically prevents ever-greening by rejecting patents for mere discoveries of new forms of known substances unless they show significantly enhanced therapeutic efficacy (upheld in Novartis-Glivec case). |
| What is Compulsory Licensing and its status under TRIPS? | - Compulsory Licensing (Sections 84/92): Allows the government to license third parties to manufacture a patented drug without the owner's consent in national emergencies, fully permitted under WTO TRIPS. |
| Define TKDL and its primary objective. | - TKDL (Traditional Knowledge Digital Library): A digital database documenting traditional Indian medicine (Ayurveda, Unani, Siddha) in multiple languages to prevent biopiracy and erroneous patents abroad. |
Other IPR Categories
| Detail the term and scope of Copyright, Trademark, GI, and Industrial Design. | - Copyright: Protects literary, musical, and artistic works. Valid for 60 years after the author's death. Includes a "Fair Use" clause (Section 52) for education and research. - Trademark: Protects distinctive brand signs/logos. Registered for 10 years (renewable). - Geographical Indication (GI): Identifies goods originating from a specific region with unique qualities (e.g., Darjeeling Tea). Registered for 10 years (renewable). - Industrial Design: Protects aesthetic aspects (shape/pattern). Valid for 10 years, extendable to 15 years. - Trade Secrets: Protects confidential business formulae (e.g., recipes) indefinitely, as long as kept secret. |
5. Specialized Space & Earth Concepts
Quasars & Earth Dynamics
| What is a Quasar and the Chandler Wobble? | - Quasar: An extremely luminous active galactic nucleus powered by a supermassive black hole at the center of a distant galaxy. Chandler Wobble: A small, natural deviation in the Earth's axis of rotation relative to the solid Earth, occurring over a period of roughly 433 days. |
