UPSC Prelims 2009 Q140: Science & Technology – Physics
- (a) European Space Agency
- (b) European Organization for Nuclear Research
- (c) International Atomic Energy Agency
- (d) National Aeronautics and Space Administration
Answer: (b) European Organization for Nuclear Research
Explanation
Who conducted the 2008 subatomic particle acceleration experiment
This landmark physics experiment involved accelerating particles to near light-speed, conducted by a specific major research organization.
| Option | Verdict | Reason |
|---|---|---|
| (a) European Space Agency | Incorrect | Focuses on space exploration, not this particle physics experiment |
| (b) European Organization for Nuclear Research | Correct | CERN conducted this landmark experiment in 2008, using the Large Hadron Collider (LHC) to accelerate subatomic particles to near light-speed |
| (c) International Atomic Energy Agency | Incorrect | Focuses on nuclear safety/non-proliferation, not this specific experiment |
| (d) National Aeronautics and Space Administration | Incorrect | Focuses on space exploration, not this particle physics experiment |
CERN's 2008 experiment facts:
| Point | Detail |
|---|---|
| Organization | CERN (European Organization for Nuclear Research) |
| Facility | Large Hadron Collider (LHC) |
Answer: (b) European Organization for Nuclear Research.
Why each option is right or wrong
- (a) Incorrect. The European Space Agency focuses on space, not this particle physics experiment.
- (b) CORRECT. CERN conducted this landmark experiment using the Large Hadron Collider.
- (c) Incorrect. The IAEA focuses on nuclear safety/non-proliferation, not this experiment.
- (d) Incorrect. NASA also focuses on space, not this particle physics experiment.
Key point
CERN (European Organization for Nuclear Research) conducted the 2008 experiment accelerating subatomic particles to near light-speed, using the Large Hadron Collider.
Remember
The 2008 subatomic particle acceleration experiment was conducted by CERN (European Organization for Nuclear Research).
Common mistakes
- Confusing CERN's particle physics work with space agencies (ESA, NASA).
- Mixing up CERN with nuclear-safety-focused bodies like the IAEA.
- Not knowing the specific Large Hadron Collider facility behind this 2008 experiment.
Exam tip
CERN = Large Hadron Collider, particle acceleration experiments — distinct from space agencies (ESA, NASA) or nuclear-safety bodies (IAEA).
