  • Mohenjo-daro’s “Dancing Girl”: History, Identity and the Debate on Modesty

    Why in News?

    The National Council of Educational Research and Training (NCERT) restored the original image of the iconic Mohenjo-daro bronze figurine in a Class 9 textbook after an earlier version had shaded its bare torso, reviving debates over cultural representation and historical interpretation.

    About the Figurine

    • A bronze statuette discovered at Mohenjo-daro (1926), dating to the Indus Valley Civilization (c. 2500 BCE).
    • About 10.5 cm tall, created using the lost-wax casting technique.
    • Depicts a young female figure adorned with numerous bangles and ornaments.

    Why is its Identity Contested?

    • Archaeologist John Marshall identified it as a “nautch girl” (dancing girl) based on posture and appearance.
    • However, scholars argue there is no archaeological evidence that she was a professional dancer.
    • Historian Upinder Singh notes that the figure “may not have been dancing at all.”
    • Archaeologist Gregory L. Possehl also questioned the dancer interpretation.

    Partition and Ownership Debate

    • After Partition, around 12,000 Harappan artefacts in Delhi became subjects of dispute between India and Pakistan.
    • Both countries agreed to a 50:50 division of artefacts from Mohenjo-daro and Chanhu-daro.
    • Pakistan chose the “Priest King” figurine over the Dancing Girl, reportedly due to concerns over the latter’s nudity.
    • The Dancing Girl remains in India and is viewed by many scholars as part of the shared heritage of South Asia.

    Significance

    • Demonstrates the advanced metallurgical skills of the Indus Valley Civilization.
    • Highlights how colonial interpretations and contemporary moral values shape our understanding of the past.
    • Reflects debates on heritage ownership, gender, modesty, and cultural identity.

    Value Addition

    • Lost-Wax Casting Technique: A metal casting process in which a wax model is covered with clay; molten metal replaces the melted wax to create the final sculpture.
    • The Dancing Girl is one of the most iconic artistic representations of the Indus Valley Civilization.

  • GRAPES-3: A Cosmic-Ray Tracker

    Why in the news?

    Researchers from India and Japan used the Gamma Ray Astronomy PeV EnergieS phase-3 (GRAPES-3) telescope to analyse 22 years of muon data, enabling real-time monitoring of changes in the Earth’s upper atmosphere.

    What is GRAPES-3?

    • GRAPES-3 (Gamma Ray Astronomy PeV EnergieS phase-3) is a muon telescope and cosmic-ray observatory located at Ooty, Tamil Nadu.
    • It detects muons, rather than visible light.
    • It is designed to study Cosmic rays, Solar magnetic fields, Space weather, and Atmospheric processes.

    What are Muons?

    • Muons are high-energy subatomic particles produced when cosmic rays collide with atoms in the Earth’s upper atmosphere.
    • They can penetrate deep into the Earth’s surface due to their high energy.

    How does GRAPES-3 Work?

    • Comprises 16 detector modules.
    • Each module contains 232 proportional counters filled with argon-methane gas and a tungsten wire.
    • Passing muons generate electrical pulses, recorded as “hits.”
    • Four layers of detectors arranged at right angles help determine the trajectory and angle of incoming muons.
    • Reinforced concrete layers filter out low-energy particles, allowing only high-energy muons to be detected.

    Significance

    • Enables real-time monitoring of upper atmospheric temperature changes.
    • Helps study the Sun’s magnetic field and space weather.
    • Improves understanding of cosmic-ray interactions with Earth’s atmosphere.
    • Contributes to research in astroparticle physics and atmospheric science.

    Value Addition

    • Cosmic Rays: High-energy charged particles originating from outer space.

      • Seasonal rainfall forecast revised from 92% to 90% of the Long Period Average (LPA).
      • Assigned a 60% probability of a deficient monsoon, the most pessimistic pre-season forecast since 2015.
      • No positive Indian Ocean Dipole (IOD) expected to offset El Niño effects.

    Significance

    • Threatens kharif sowing and agricultural output.
    • May increase food inflation and rural distress.
    • Necessitates timely contingency planning and climate-resilient agriculture.
