Prelims level: Vijayanagara Empire

Why in the News?

A set of copper plates from the early 15th Century, dating back to the reign of Devaraya I of the Sangama Dynasty, were recently unveiled by the Archaeological Survey of India (ASI).

About the Sangama Dynasty 

  • The Sangama Dynasty was the first ruling dynasty of the Vijayanagara Empire, founded in the 14th century by brothers Harihara I and Bukka Raya I.
  • They were the sons of Bhavana Sangama, a chieftain from a pastoralist community with Yadava descent.
  • The Sangama Dynasty was established in 1336 CE by Harihara I and Bukka Raya I, who founded the city of Vijayanagara on the south bank of the Tungabhadra River.
  • The early rulers focused on building the foundations of the empire, both administratively and culturally.

Notable Rulers

  • Harihara I: Known for founding the empire and laying its initial foundations.
  • Bukka Raya I: Expanded the empire’s territories significantly, ruling from 1343 to 1379 CE.
  • Harihara II: Conquered coastal Andhra and important Indian ports like Goa, continuing his predecessor’s expansion.
  • Deva Raya I: Ruled from 1404 to 1422 CE, further expanding the empire.
  • Deva Raya II (Krishnadeva Raya): Regarded as one of the greatest rulers of the dynasty, he expanded the empire and promoted art, literature, and diplomacy from 1422 to 1446 CE.

Downfall

  • Internal conflicts, particularly succession disputes, and external pressures from the Bahmani Sultanate and neighboring kingdoms weakened the dynasty.
  • The final blow came when Narasimha of the Saluva Dynasty usurped the throne in 1485 CE, marking the end of the Sangama Dynasty’s reign.

Key Features of the Copper Plates

  • These plates are unique, dating back to the coronation of King Devaraya I of the Vijayanagara Empire.
    • The king granted the village of Gudipalli, along with the hamlets Rajendramada and Udayapalli, during his coronation.
    • The village was renamed Devarayapura-agrahara and divided into 61 shares allocated to various Brahmins with expertise in Vedas and Shastras.
  • They are written in Sanskrit, Kannada and Nagari characters.
  • The seal features an image of Vamana, rather than the usual Varaha (boar), which is the royal insignia of the Vijayanagara Empire.

Historical Significance:

  • Dated to Saka 1328 (November 5, 1406 CE), the plates provide insights into the Sangama Dynasty.
  • It helps trace the lineage from Chandra, Yadu, and Sangama to the five sons of King Harihara: Harihara, Kampa, Bukka, Mãrapa, and Muddapa.

Prelims Only | Economics | Mains Paper 3: Indian Economy
Note4Students

From UPSC perspective, the following things are important :

Prelims level: Evolution of RBI's Monetary Policy

Why in the News?

The first monetary policy of RBI Governor Sanjay Malhotra in 2025 marks 90 years since the Reserve Bank of India (RBI) announced its inaugural monetary policy in 1935.

RBI’s First Monetary Policy in 1935

  • On July 3, 1935, RBI set the bank rate at 3.5%, reflecting the Imperial Bank’s rate.
  • The CRR was set at 5% of demand liabilities and 2% of time liabilities on July 5, 1935.

Evolution of RBI’s Monetary Policy

  • Bank Rate in Early RBI History:
    • The bank rate was a key tool introduced by the RBI in 1935 to control credit and liquidity. On July 3, 1935, the RBI set the bank rate at 3.5%, mirroring the rate of its predecessor, the Imperial Bank of India.
    • The RBI Act (1934) mandated its use for buying or re-discounting commercial paper, and it played a crucial role in India’s interest rate structure.
  • Role of Cash Reserve Ratio (CRR):
    • The CRR, introduced by the RBI, required banks to maintain a percentage of their deposits as reserves.
    • Influenced by the Federal Reserve Act of the USA, the CRR helped stabilize the banking system, especially during failures.
    • The CRR was set at 5% for demand liabilities and 2% for time liabilities in 1935, with adjustments made over time.
  • Exchange Rate Management
    • In 1935, the RBI managed the exchange rate of the 1 Indian rupee at 1 shilling and 6 pence.
    • This caused friction between nationalists, who favoured a lower exchange rate to boost exports, and the British, who preferred a higher rate to facilitate cheaper imports.
  • Disputes Between Government and RBI
    • The RBI’s decision to reduce the bank rate in 1935 was opposed by the government, fearing rupee depreciation.
    • This led to a conflict, resulting in the resignation of Osborne Smith, the first RBI Governor.
    • The incident highlighted tensions between the RBI’s monetary autonomy and government priorities.

About Reserve Bank of India (RBI)

  • The RBI is the central bank and monetary authority of India established on April 1, 1935, under the Reserve Bank of India Act, 1934.
  • Its idea was incepted from the recommendations of the Hilton Young Commission.
  • Sir Osborne Arkell Smith, an Australian, served as the inaugural Governor.
  • He was succeeded by Sir C D Deshmukh, the first Indian to hold the position.
  • It is a centralized institution for India to effectively regulate its monetary and credit policies.
  • RBI had its initial headquarters in Kolkata, later moving permanently to Mumbai in 1937.
  • Initially, the RBI operated as a privately owned entity until its full nationalization in 1949.

Functions and Initiatives:

  • Monetary Authority: The RBI controls the supply of money in the economy to stabilize exchange rates, maintain a healthy balance of payment, and control inflation.
  • Issuer of Currency: Sole authority to issue currency and combat circulation of counterfeit notes.
  • Banker to the Government: Acts as a banker to both the Central and State governments, providing short-term credit and financial advisory services.
  • Lender of Last Resort: Provides emergency liquidity assistance to banks during crises.
  • Custodian of Foreign Exchange Reserves: Manages foreign exchange reserves and administers the Foreign Exchange Management Act, 1999 (FEMA).
  • Regulator and Supervisor of Payment and Settlement Systems: Oversees payment and settlement systems in the country, ensuring efficiency and security.
  • Credit Control and Developmental Role: Promotes credit availability to productive sectors and fosters financial infrastructure development.

Dr. Ambedkar’s Role in the Establishment of RBI:

  • Dr. B.R. Ambedkar’s contributions were particularly notable during the Hilton Young Commission discussions in 1926, where he presented his recommendations based on his book “The Problem of the Rupee – Its Origin and Its Solution.”
  • These discussions laid the foundation for establishing the RBI on April 1, 1935.

 

[UPSC 2004] Consider the following statements:

1. Reserve Bank of India was nationalized on 26 January 1950.

2. The borrowing programme of the Government of India is handled by the Department of Expenditure, Ministry of Finance.

Majorana 1 Chip and the Pursuit of Quantum Computing

Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields
Note4Students

From UPSC perspective, the following things are important :

Prelims level: Majorana 1 Chip, Majorana particles

Why in the News?

In December 2024, Microsoft introduced its quantum computing chip, Majorana 1, designed to solve industrial-scale problems by utilizing the properties of Majorana particles for practical quantum computing.

About Majorana 1 Chip and the Science Behind

  • Microsoft introduced its Majorana 1 quantum computing chip, designed to solve large-scale problems using quantum computing.
  • This chip is named after Majorana particles, which have unique properties in particle physics.
  • Majorana particles are special because they are their own anti-particles.
  • This means that when two Majorana particles meet, they destroy each other and release energy.
  • This property is different from most particles, like electrons, which have separate anti-particles (for example, the electron’s anti-particle is the positron).
  • Why Majorana Particles Matter for Quantum Computing?
    • This unique property could make Majorana particles useful in quantum computing.
    • They could help make quantum bits (qubits) more stable, which is important for improving quantum computers.
    • Using Majorana particles may also help in topological quantum computing, which makes qubits less affected by external disturbances, making them more reliable.

Beta Decay and Neutrinoless Double Beta Decay (0vßß):

  • Beta decay happens when an unstable atomic nucleus releases energy. In this process, a neutron in the nucleus turns into a proton, and an electron and anti-neutrino are emitted. There are two types of beta decay:
  1. Beta-minus decay: A neutron becomes a proton, releasing an electron and an anti-neutrino.
  2. Beta-plus decay: A proton turns into a neutron, releasing a positron and a neutrino.
  • What is Neutrinoless Double Beta Decay (0vßß)? Neutrinoless double beta decay is a rare event where two electrons are emitted instead of the usual electron and anti-neutrino. This suggests that neutrinos and anti-neutrinos might be the same particle, known as Majorana particles.
    • If scientists observe this type of decay, it will prove that neutrinos are Majorana particles and help measure their mass.
    • This discovery would improve our understanding of particle physics.

AMoRE Experiment:

  • The AMoRE experiment is being conducted in South Korea to detect this rare 0vßß decay.
  • The experiment uses molybdenum-100 (Mo-100), which is known to undergo double beta decay. The team is measuring the energy differences in electron emissions to detect the 0vßß decay.
  • While no evidence has been found yet, the experiment continues to improve its sensitivity by using 100 kg of Mo-100 for more accurate measurements.

Scientific Significance:

  • The search for 0vßß and studying Majorana particles could help answer important questions about the mass of neutrinos and improve our understanding of particle physics.
  • Learning more about neutrinos is key to both advancing quantum computing and understanding particle physics.
[UPSC 2022] Which one of the following is the context in which the term “qubit” is mentioned?

(a) Cloud Services (b) Quantum Computing (c) Visible Light Communication Technologies (d) Wireless Communication Technologies

IISc’s Bacteria-Based Technique for Lunar Habitat Construction

Prelims Only | Science Tech | Mains Paper 3: Achievements Of Indians In S&T
Note4Students

From UPSC perspective, the following things are important :

Prelims level: Bacterial Brick

Why in the News?

Researchers at the Indian Institute of Science (IISc.) have developed a bacteria-based technique to repair bricks used in lunar habitats, designed to withstand the harsh conditions of the moon’s environment.

About the Bacterial Brick:

  • The bacterial brick is an innovative material designed for building durable, eco-friendly structures in lunar habitats.
  • It is created using lunar soil simulants combined with Sporosarcina pasteurii, a bacteria that binds soil particles together, forming a solid material suitable for construction on the moon.
  • How is it made?
    • The bacteria Sporosarcina pasteurii converts urea and calcium into calcium carbonate crystals, which bind soil particles together to create a brick-like substance.
    • The process is further enhanced with guar gum, which serves as a natural adhesive, making it a low-cost, eco-friendly alternative to energy-intensive cement-based manufacturing.
    • The researchers also explored sintering, where a mixture of soil simulants and polyvinyl alcohol is heated to high temperatures, creating stronger, more pressure-resistant bricks.

Significance for Lunar Surface Conditions:

  • The moon’s surface experiences extreme temperature fluctuations, ranging from 121°C to -133°C, causing bricks to crack and become brittle.
  • A bacteria-based repair technique using Sporosarcina pasteurii helps address these cracks.
    • When mixed with lunar soil simulant and guar gum, the bacteria effectively adhere to cracks, improving durability and enabling the bricks to withstand temperatures from 100°C to 175°C.
  • This approach offers a sustainable solution by allowing on-site construction with local lunar materials, reducing the need for Earth-based materials.
    • It ensures long-term structural integrity for lunar habitats, contributing to the sustainability of space missions.
[UPSC 2011] Microbial fuel cells are considered a source of sustainable energy. Why?

1. They use living organisms as catalysts (often including bacteria) to generate electricity from certain substrates.

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Parker Solar Probe

Why in the News?

The Parker Solar Probe made history on December 24, 2024, by coming within 6.1 million kilometers of the Sun’s surface, marking the closest approach ever by a spacecraft.

Why the Parker Solar Probe is trying to ‘touch’ the Sun?

About Parker Solar Probe

  • The Parker Solar Probe, launched in August 2018, is a car-sized robotic spacecraft named after Eugene Newman Parker, an American solar astrophysicist.
  • It is the first NASA mission named after a living researcher, and its mission is humanity’s first to explore within 3.8 million miles of the Sun’s corona.
  • The spacecraft is equipped with an advanced carbon-composite heat shield capable of withstanding temperatures up to 1,370°C.
  • This shield, which weighs only 73 kg, is designed to protect the probe from the Sun’s intense heat.
    • The probe’s instruments remain at a manageable 29°C due to the shield’s protection.
  • The primary goals are:
    • Approach the Sun: The probe aims to get as close as 6.5 million kilometers to study the Sun’s energy flow, solar corona heating, and the sources of solar wind.
    • Explore Solar Wind: Investigate the origins and behaviour of solar wind, the high-speed streams of charged particles that impact space weather.
    • Study Solar Corona: Delve into the mystery of why the Sun’s corona is 200 times hotter than its surface.
    • Investigate Plasma and Magnetic Fields: Study the structure and dynamics of plasma and magnetic fields at the sources of solar wind.
  • The Parker Solar Probe is equipped with four primary instruments:
    • FIELDS: Measures the electric and magnetic fields of the Sun’s atmosphere.
    • ISoIS: Observes energetic particles that lead to solar storms.
    • SWEAP: Records the properties of solar wind particles.
    • WISPR: Takes images of the solar corona.
    • Faraday Cup: Measures ion and electron density in the solar wind.

Impact of the Mission on Solar Science

  • Understanding Solar Wind: The mission provides crucial data on the origins and behavior of solar wind, enhancing predictions of space weather and its impact on Earth.
  • Solving the Solar Corona Mystery: The probe’s findings suggest that Alfvén waves, plasma oscillations, may be the key mechanism responsible for the heating of the Sun’s corona, addressing a long-standing puzzle in solar physics.
  • New Discoveries on Space Dust: The probe’s discovery of dust-free pockets near the Sun challenges previous assumptions about the interaction of space dust with solar energy, offering new insights into solar dynamics.
  • Space Weather and Solar Flares: By monitoring the Sun’s activity, the probe aids in understanding solar flares and coronal mass ejections (CMEs), helping to mitigate the effects of space weather on Earth’s satellites and infrastructure.
  • Advancement in Solar Exploration Technology: The mission’s success in utilizing advanced heat shields and high-speed space travel techniques paves the way for future solar missions and deeper exploration of stellar physics.

Judicial Reforms

What are the Norms for Disclosure of Judges’ Assets?

Prelims Only | Polity | Mains Paper 2: Executive & Judiciary
Note4Students

From UPSC perspective, the following things are important :

Prelims level: Judges' Asset Disclosure

Why in the News?

The discovery of large sums of cash at Delhi High Court judges’ residence has raised concerns about corruption in India’s judiciary and reignited the debate over the public disclosure of judges’ assets and liabilities.

Current Stance on Judges’ Asset Disclosure

  • Supreme Court’s Historical Approach:
    • 1997 Resolution: The Supreme Court, under Chief Justice J.S. Verma, resolved that judges should disclose their assets to the Chief Justice of India (CJI), but this did not involve public disclosure.
    • 2009 Resolution: The full Bench of the Supreme Court agreed to publish judges’ asset declarations on the court’s website, though this was done voluntarily. However, the website has not been updated since 2018, and the assets of current judges are not publicly available.
    • 2019 Ruling: The Supreme Court ruled that judges’ personal assets and liabilities are not private information, making them subject to the Right to Information (RTI) Act.
  • High Court’s Position:
    • As of March 2024, only 13% of High Court judges have publicly disclosed their assets and liabilities. Many High Courts, including Uttarakhand and Allahabad, have opposed public disclosure and argued that such information is outside the scope of the RTI Act.
  • Resistance to Full Disclosure:
    • The Uttarakhand High Court (2012) passed a resolution opposing the disclosure of judges’ assets under the RTI Act. Similarly, many High Courts have rejected RTI applications seeking information about judges’ assets.

Parliament’s Role – Proposed Reforms

  • Committee Recommendation (2023):
    • The Parliamentary Committee on Personnel, Public Grievances, and Law and Justice recommended that legislation be introduced to make the disclosure of judges’ assets and liabilities mandatory for Supreme Court and High Court judges.
    • However, there has been no progress on implementing this recommendation as of now.
  • Need for Legislation:
    • Despite the RTI Act requiring public servants to disclose their assets, judges have largely remained exempt from such transparency.
    • Legislative action is seen as essential to ensure accountability and transparency within the judiciary, with several advocating for mandatory public disclosure similar to other public officials.
[UPSC 2017] With reference to the appointment of the High Court Judges, consider the following statements:

1. Chief Justice of India is consulted by the President in the appointment.

2. Governor of the State is consulted by the Chief Justice of India in the appointment.

Which of the statements given above is/are correct?

(a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Earthquakes

Why in the News?

A powerful 7.7 magnitude earthquake struck Myanmar, with its epicentre near Mandalay, the country’s second-largest city.

Massive Earthquake hits Myanmar and Thailand

What caused the Earthquake in Myanmar?

  • Myanmar is situated between the Indian Plate and the Eurasian Plate, which makes the region seismically active.
    • The Sagaing Fault, running from north to south through Myanmar, marks the boundary of these plates.
    • It is an active fault line that has caused significant earthquakes in the past, including a 7.9 magnitude earthquake in 1912 and a 6.9 magnitude earthquake in 2016.
  • The Indian Plate was moving northward along the Sagaing Fault relative to the Eurasian Plate. The friction and stress built up along this fault led to a sudden release of energy, resulting in the earthquake.
  • The earthquake’s epicentres was located 17.2 km from Mandalay, Myanmar’s second-largest city, at a depth of just 10 km.

Why are Shallow Earthquakes more destructive?

  • Proximity to the Surface: Shallow earthquakes (less than 70 km deep) cause intense shaking. For example, the Myanmar earthquake occurred at 10 km, leading to rapid, forceful seismic waves and extensive damage.
  • Energy Release: Shallow earthquakes retain more energy in seismic waves, causing stronger surface shaking and greater destruction.
  • Higher Intensity: Shallow quakes produce higher intensity shaking, resulting in more structural damage compared to deeper quakes, where seismic waves lose energy.
  • Aftershocks: Shallow earthquakes often lead to more intense aftershocks, further damaging already weakened structures. The Myanmar earthquake had aftershocks, including one with magnitude 6.4.

Back2Basics: Earthquake and Related Terminologies

  • Earthquake is a sudden shaking of the ground caused by energy release from tectonic plate movements or volcanic activity, generating seismic waves.
  • Key Terminologies:
    • Focus (Hypocenter): The point inside the Earth where the earthquake originates, deep beneath the surface.
    • Epicenter: The point on the Earth’s surface directly above the focus, usually the most affected area.
    • Seismic Waves: Waves that carry the energy released during an earthquake and cause ground shaking.
    • Fault: A crack or fracture in the Earth’s crust where movement occurs, often causing earthquakes.
    • Magnitude: A measure of the earthquake’s size or energy, commonly measured on the Richter scale.
    • Intensity: The strength of shaking at specific locations, measured by the Modified Mercalli Intensity (MMI) scale.

Types of Earthquake Waves:

  • Body Waves: Travel through the Earth’s interior, detected first by seismographs.
    • Primary Waves (P-Waves): Fastest, compression waves that move through solids and liquids.
    • Secondary Waves (S-Waves): Shear waves, slower than P-waves, that move through solids only.
  • Surface Waves: Travel along the Earth’s surface, slower but cause more damage.
    • Love Waves: Move side-to-side horizontally, causing significant damage.
    • Rayleigh Waves: Cause elliptical ground motion, similar to ocean waves, very destructive.

 

[UPSC 2021] Consider the following statements:

1. In a seismograph, P waves are recorded earlier than S waves.

2. In P waves, the individual particles vibrate to and fro in the direction of waves propagation whereas in S waves, the particles vibrate up and down at right angles to the direction of wave propagation.

Who was Rana Sanga (1484–1527)?

Prelims Only | History and Art & Culture | Mains Paper 1: Arts & Culture
Note4Students

From UPSC perspective, the following things are important :

Prelims level: Rana Sanga

Why in the News?

A recent statement by an MP in Parliament labelling Rajput ruler Rana Sanga a “traitor,” has sparked controversy over his role in inviting Babur to invade India.

Who was Rana Sanga?

  • Rana Sanga, also known as Maharana Sangram Singh, was a Rajput king who ruled the kingdom of Mewar in present-day Rajasthan from 1509 to 1527.
  • He expanded his kingdom significantly, conquering parts of Madhya Pradesh, Gujarat, Haryana, and Sindh.
  • He formed a powerful Rajput confederacy and led a massive army of 80,000 warhorses and 500 elephants.
  • He was known for his military campaigns against the Lodi dynasty of Delhi, the Sultanates of Malwa and Gujarat, and even the Mughals.
  • His most notable victories include the Battle of Gagron against Sultan Mahmud Khilji of Malwa and the Battle of Dholpur in 1519 against Ibrahim Lodi of Delhi.
  • Battle with Babur:
    • Rana Sanga eventually came into conflict with Babur, the founder of the Mughal Empire.
    • The two fought in the Battle of Khanwa in 1527, where Babur’s forces defeated Sanga’s Rajput army.
    • This marked the end of Rajput resistance to the Mughals in Northern India.
  • Legacy:
    • Despite his defeat at Khanwa, he is remembered as a hero of Rajput resistance and is considered one of the last independent Hindu rulers in Northern India before the rise of Mughal dominance.

Recent Controversy:

  • The remarks were made amid growing debates about Medieval Indian history, particularly surrounding Aurangzeb and the role of various historical figures in Indian politics.
  • Historians are divided on whether Rana Sanga explicitly invited Babur to invade India.
  • Babur’s memoirs, the Baburnama, mention that Rana Sanga offered assistance against Ibrahim Lodi.

Why in the News?

Opposition parties have raised concerns over the Digital Personal Data Protection (DPDP) Act, 2023, demanding the repeal of Section 44(3), claiming it could undermine the Right to Information (RTI) Act, 2005.

About DPDP Act and Section 44(3)

  • Recognizing the right to privacy as fundamental in India, the Supreme Court in Justice K.S. Puttaswamy vs. Union of India (2017) led to the introduction of the DPDP Act in 2023.
  • The Act regulates the processing of personal data, balancing individual privacy rights and lawful processing needs.
  • Key Provisions: It mandates informed consent, establishes a Data Protection Board of India (DPBI), and outlines the responsibilities of data fiduciaries in ensuring data protection.
  • Section 44(3) modifies Section 8(1)(j) of the RTI Act, which previously exempted personal information from disclosure unless public interest justified it.
  • The amendment broadens this exemption, stating that all personal information should be exempt from disclosure, without requiring a public interest justification.

Concerns Related to Section 44(3)  

  • Reduced Transparency: Activists and critics argue that this section undermines the RTI Act, which has been a cornerstone of transparency and accountability in governance.
  • Limited Access to Public Information: The broad exemption allows government officials to shield information like asset disclosures, which are critical for public accountability.
  • Potential for Misuse: There are concerns that personal data protection could be used as an excuse to block vital information about government activities, weakening the public’s right to know.
  • Conflict Between Public Interest and Privacy: Critics argue that privacy protection should not override the principle of transparency.
