    Tipu Sultan’s Contested Legacy

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Tipu Sultan

    Mains level: His legacy

    tipu

    Central idea: The article examines the controversial nature of Tipu Sultan’s legacy and the differing opinions about his reign and his place in Indian history. It discusses the contrasting views of Tipu Sultan as a hero and patriot who fought against British colonialism, or as a tyrant who persecuted Hindus and Christians.

    Rise of Tipu Sultan

    • Tipu Sultan was born on November 10, 1750, in Devanahalli, present-day Bangalore.
    • His father was Hyder Ali, who rose through the ranks of the army of the Wodeyars, the Hindu rulers of Mysore.

    Rise to power

    • Hyder Ali seized power from the Wodeyars in 1761 and ruled for 20 years, a period in which the kingdom of Mysore had slowly expanded by capturing disputed areas at its borders.
    • During this time, Tipu was educated in both matters of statecraft and warcraft, participating in his first battle at the age of only 15.
    • When Hyder Ali died in 1782, Tipu’s primary motivation was to consolidate the territory he had inherited from his father.
    • Specifically, the rebellious provinces of Malabar, Kodagu, and Bednur, were crucial to Mysore’s strategic and economic interests.
    • His rule in these areas is what is often cited as proof of his bigotry and authoritarianism.

    Contribution to freedom struggle

    • In the course of India’s freedom struggle, Tipu Sultan became a symbol of resistance against British rule.
    • His death while defending his fortress of Srirangaptna against British armies in 1799 was valorised as the ultimate sacrifice for the motherland.

    Reforms carried out by Tipu

    Administrative reforms

    • Tipu Sultan also pioneered administrative and economic reforms.
    • He introduced new coins, started a new land revenue system in Mysore, as well as introduced sericulture or silkworm cultivation, which continues to employ many Kannadigas to date.
    • Furthermore, some claim that upon hearing of the plight of lower caste women who were not allowed to wear blouses, Tipu personally supplied them with cloth.

    Modernization of weaponry: Advent of Rockets

    tipu

    • Tipu is credited for the introduction of iron-cased rockets in warfare.
    • While rocket-like weapons had previously been used in War, Tipu’s army used what can be termed as the first modern war rockets in the Anglo-Mysore Wars.
    • These rockets were used to devastating effects against much larger British armies, driving them to panic and disarray.
    • The British used Tipu’s models for their own rockets, which would go on to play an important role in the Napoleonic Wars.

    Scientific temper

    tipu

    • Tipu’s fascination with European culture was a result of what he saw while fighting Europeans.
    • Tipu wanted Mysore to be a modern rival of the European powers and made investments in technology accordingly.

    Why is Tipu branded as a tyrant?

    • Warfare in Tipu’s time was brutal and those who rebelled were dealt with an iron fist. It was common practice to set strong examples to forestall future opposition.
    • The punishments Tipu applied to rebels or conspirators included forced conversion and the transfer of people from their home territories to Mysore.
    • The forced removals occurred from both Kodagu and Malabar, the former as a response to continued resistance against Mysore rule– as a result of their resistance and perceived treachery in the Anglo-Mysore Wars.
    • The right’s narrative of Tipu’s bigotry emphasizes Tipu’s militarism as well as his perceived attacks on “Hindu” rulers and subjects.

    Historian’s justification of Tipu’s actions

    • Tipu’s actions are questionable by today’s standards, they were commonplace in the 18th century among rulers of all faiths.
    • He was a tyrant, but his motivations were not necessarily religious zealotry.
    • Rather, he was a pragmatist who ruled within the accepted conventions of kingship and warfare at the time.
    • He undoubtedly ordered forced conversions in areas he annexed, Tipu also patronized various temples and Hindu shrines, including the Sri Ranganatha temple at Srirangapatna and the Math in Sringeri.
    • Both these actions were to solidify his position as a ruler — the former to crush dissidents and the latter to gain legitimacy among his largely Hindu subjects.

    Tipu’s legacy: looking at the past from the prism of the present

    • Today, there has been an increased spotlight on his autocratic tendencies and brutal repression in annexed territories, with an increased emphasis on his religion.
    • Both portrayals fall short, missing the complexity of Tipu’s character and material circumstances.

    Anti-encroachment drive in historic city of Mehrauli

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Mehrauli

    Mains level: History of Delhi

    mehrauli

    The Delhi Development Authority (DDA) carried out an anti-encroachment drive in the nearby villages of Mehrauli and Ladha Sarai leaving hundreds of families in uncertainty about their future.

    History of Delhi

    • Purani Dilli, commonly referred to as Old Delhi, is a misnomer as the city’s history dates back to before the establishment of Shahjahanabad.
    • The oldest evidence of habitation in Delhi, dating back to the Iron Age (around 1100-800 BC), is the painted grey ware fragments found in Purana Quila.
    • Historians recognize seven cities of Delhi, from the 11th century onwards, namely Lalkot/Quila Rai Pithora/Mehrauli, Siri, Tughlaqabad, Firozabad, Shergarh (Old Fort), Shahjahanabad, and New Delhi.
    • However, depending on what is considered a city, this number can be as high as 11.

    In focus: City of Mehrauli

    • Mehrauli is widely considered to be the oldest ‘city’ of Delhi and is the oldest area of the metropolis to be continuously inhabited.
    • It was first built by a ruler called Anangpal II in the 11th century, and it was called Lalkot.
    • Later, it was known as ‘Quila Rai Pithora’ and was fortified by the Chauhans.
    • The Mamluk dynasty took control of the city in 1192, and Qutubudin Aibak, the first ruler of the dynasty, built the Qutub Minar and the Quwwat-al-Islam mosque (oldest mosque in North India).
    • In the following century, more buildings like tombs, step wells, palaces, and fortifications were constructed during the reigns of Iltutmish, Razia Sultan, and Alauddin Khilji.

    Continued relevance and inhabitation

    • Even as the newer cities came up and the seat of power shifted northwards, Mehrauli witnessed building activity as late as the Mughal and British periods.
    • Due to its location on the lap of the Aravallis hills, the area was preferred as a summer retreat.
    • Two Mughal summer palaces (Zafar Mahal and Jahaz Mahal) and a summer abode of Sir Thomas Metcalfe (Dilkhusha) are situated here.
    • Mehrauli lay on a historic trade route, as the number of sarais (Ladho Sarai, Ber Sarai, Neb Sarai) around the area would suggest. A sarai was a resthouse for weary travellers.

    Cultural significance of Mehrauli

    • Mehrauli is also a spiritual centre. Sufi saint Hazrat Qutubuddin Bakhtiar Kaki (1173 -1235 AD) was buried in the city and his dargah remains popular till date, across religious lines.
    • Some historians cite the dargah as a reason for the city surviving the test of time – despite power shifting elsewhere, the dargah remained a revered destination for pilgrims far and wide.
    • Another spiritual centre for the community is the Yogmaya mandir, believed to be one of the oldest in the city.
    • Yoginis (semi-divine deities) have been an integral part of Indian folklore and this temple dedicated to them is believed to have been constructed by the Pandavas.

    How it ended up in encroachments?

    • Like much of the rest of Delhi, the Partition brought many changes to Mehrauli too.
    • Many refugees from the West found sanctuary here. The city has also seen sectarian tensions.

    Thwaites glacier at mercy of sea warmth increase

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Thwaites Glacier

    Mains level: Sea Level rise

    thwaites

    The new research suggests that even low amounts of melting can potentially push Thwaites glacier further along the path toward eventual disappearance.

    Thwaites Glacier

    • Called the Thwaites Glacier, it is 120 km wide at its broadest, fast-moving, and melting fast over the years.
    • Because of its size (1.9 lakh square km), it contains enough water to raise the world sea level by more than half a meter.
    • Studies have found the amount of ice flowing out of it has nearly doubled over the past 30 years.
    • Thwaites’s melting already contributes 4% to global sea-level rise each year. It is estimated that it would collapse into the sea in 200-900 years.
    • Thwaites is important for Antarctica as it slows the ice behind it from freely flowing into the ocean. Because of the risk it faces — and poses — Thwaites is often called the Doomsday Glacier.

    How is Thwaites glacier melting?

    thwaites

    • Thwaites Glacier is melting due to a combination of warming ocean currents and a weakening of the ice shelf that acts as a barrier between the glacier and the ocean.
    • The cause of the melting is thought to be the influx of relatively warm bottom water drawn in from the wider ocean.
    • In the 1990s it was losing just over 10 billion tonnes of ice a year. Today, it’s more like 80 billion tonnes.

    Why is this glacier so important?

    • Huge size: Flowing off the west of the Antarctic continent, Thwaites is almost as big as Great Britain.   It is one of the largest and most important glaciers in Antarctica, as it acts as a gateway to a vast area of the continent.
    • Melting faster: It’s a majestic sight, with its buoyant front, or “ice shelf”, pushing far out to sea and kicking off huge icebergs. But satellite monitoring indicates this glacier is melting at an accelerating rate.
    • Seal level rise: Thwaites’ ice loss contributes approximately 4% to the annual rise in global sea-levels, with the potential to add 65cm in total should the whole glacier collapse.  Its melting could also destabilize the entire West Antarctic Ice Sheet, leading to a further rise in sea levels.

    Ring around a dwarf planet lies in Roche Limit: What it means, why it matters

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Roche Limit, Quaoar, Dwarf Planets

    Mains level: Not Much

    roche limit

    Central idea: A new study shows that a dwarf planet, named Quaoar, has a ring system that exists within its Roche limit.

    What is the news?

    • Astronomers have found a ring around a dwarf planet, located in the Kuiper Belt at the solar system’s edge, called Quaoar, according to a new study.
    • The ring, however, is positioned much further away from the planet than is usual and defies theoretical explanations.

    About Quaoar

    • With an estimated radius of 555 km, Quaoar is roughly half the size of Pluto and orbits beyond Neptune.
    • It also has a moon of its own, which is known as Weywot.
    • As the dwarf planet is too small and too distant to be observed directly, the researchers detected the ring with the help of a phenomenon called stellar occultation.

    How was the ring discovered?

    • A stellar occultation occurs when, as seen from Earth, a bright star passes behind a planet.
    • This allows astronomers or anybody on Earth to observe the sharp silhouette of the planet for a brief period of time.
    • The phenomenon, which rarely occurs, is used by researchers to analyze a planet’s atmosphere and determine if it has a ring around it — in 1977, scientists discovered the Uranian ring system with the help of stellar occultation.

    What is the Roche limit?

    • The most intriguing part of the findings is the distance between Quaoar and its ring.
    • Located 2,500 miles away from the dwarf planet, the ring is around 1,400 miles further away from the Roche limit, as per the calculations of the scientists.
    • It suggests that at such a distance, the particles of the ring should have come together to form a moon.
    • For a further understanding of the Roche limit, let’s look at the Earth and the moon. The Earth’s gravity pulls on the moon.
    • However, one side of the moon is closer to the planet and hence, the pull is stronger on the side facing the Earth.
    • The result is the so-called tidal force, which either stretches or compresses the moon from all sides.

    What is the reason behind Quaoar’s far-out ring?

    • As of now, nobody exactly knows how Quaoar’s ring has managed to remain stable at such a distance from the Roche limit.
    • The researchers said that there can be a variety of possible explanations but they aren’t sure about any one of them.
    • It might be possible that Quaoar’s moon, Weywot, or some other unseen moon contributes gravity that somehow holds the ring stable.
    • Another potential explanation can be that the particles of the ring are colliding with each other in such a way that they are avoiding to coalesce into a moon.

     

    Try this MCQ:

    Q.What is the Roche limit?

    A) The distance from a planet where its gravity is balanced by the gravitational force of another celestial body

    B) The minimum distance from a planet that a moon can orbit without being pulled apart by tidal forces

    C) The distance from the sun at which a planet can have a stable orbit

    D) The distance from the earth where meteoroids burn up upon entering the atmosphere

    Folk dance in news: Lavani

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Lavani

    Mains level: NA

    lavani

    Central idea: The article is based on the controversy surrounding the Maharashtra folk dance form, Lavani, which has come under criticism for being ‘vulgar’ and ‘obscene’.

    What is the Lavani folk art form?

    • The word Lavani comes from ‘lavanya’ or beauty.
    • Lavani is a traditional folk art form in which women dancers wearing nine-yard-long sarees in bright colours, make-up, and ghunghroos perform on dholak beats on a stage before a live audience.
    • As an indigenous art form, Lavani has a history going back several centuries, and it attained particular popularity in the Peshwa era in the 18th century.
    • Traditionally, performances were held in front of kings or lords, and for the entertainment of tired soldiers resting during breaks in fighting.

    Genres of Lavani

    • There are several types of Lavani, of which the most popular is the Shringarik (erotic) kind, in which the lyrics are often teasing, with sensuous dance steps and delicate gestures employed to convey erotic meaning.
    • Over the years, Lavani has gained more acceptability among the people, even though certain taboos around it continue.
    • The audience has historically been all-male, but in recent years, some women too have begun to attend performances.

    Why is it under fire these days?

    • Lost its original form: Some also argue that the commercialization of Lavani has led to a loss of authenticity and cultural significance.
    • Objectifying women: The criticism of Lavani dance centres on the traditional dance form’s alleged objectification and commodification of women’s bodies.
    • Public obscenity: It has been accused of promoting obscenity and vulgarity and reinforcing patriarchal attitudes towards women.
    • Communalizing/Stereotyping: Critics have also argued that the dance form perpetuates negative stereotypes of women from marginalized communities, such as the notion that Dalit women are “loose” or sexually promiscuous.

    InfoCrop v2.1: Indigenous Crop Simulator

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: InfoCrop v2.1

    Mains level: Use of AI in agriculture

    infocrop

    Central idea: Scientists at the Indian Agricultural Research Institute conducted an experiment using InfoCrop version 2.1 to quantify the impact of hot weather on crop yield in Punjab and Haryana.

    What is InfoCrop v2.1?

    • InfoCrop version 2.1 is India’s only dynamic crop simulation model developed and released by the IARI in 2015 to study the long-term impact of climate change and crop management practices on yield.
    • InfoCrop is more suited for India as it has the life cycle data for almost all the local varieties of 11 crops: paddy, wheat, maize, sorghum, pearl millet, pigeon pea, chickpea, soybean, groundnut, potato and cotton.

    How does it work?

    • In InfoCrop, the parameters are already calibrated to Indian crop varieties and they are updated at regular intervals by the institute.
    • The parameters deal with aspects of-
    1. Weather (precipitation, temperature, radiation and others)
    2. Crop growth (phenology, grain characteristics, leaf growth, temperature and flooding sensitivity and others)
    3. Soil (texture and organic carbon, water holding characteristics and pH levels) and
    4. Pests and crop management (organic matter, fertiliser and irrigation).

    Efficiency of InfoCrop model

    • The model has an 85 per cent accuracy rate.
    • This is on par with widely used dynamic models such as the Decision Support System for Agrotechnology Transfer model, developed by the US, and Agriculture Production Systems sIMulator, developed by Australia.

    Utility of this tool

    • Prevent on-field corruption: India currently relies on field trials, which are expensive and resource-intensive as well as highly corrupt practise.
    • Crop insurance prediction: Government and insurance companies can use this for climate impact projections and for pre- or in-season crop yield forecasts to improve accuracy.
    • Assess crop loss: Besides forecasting, simulation models can be used to assess crop loss in the aftermath of an extreme weather event, which can then be used to provide relief packages.

    Marburg Virus

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Marburg Virus

    Mains level: Rise in zoonotic diseases

    Central idea: Equatorial Guinea has confirmed its first-ever outbreak of Marburg virus disease.

    Where is Equatorial Guinea located?

    marburg

    • Equatorial Guinea is a country located in Central Africa.
    • It is situated on the west coast of Africa, bordered by Cameroon to the north and Gabon to the south and east. It also includes two small islands, Bioko and Annobon, which are located in the Atlantic Ocean.

     

    Marburg Virus

    • The Marburg virus is a highly dangerous pathogen that targets several organs and reduces the body’s ability to function on its own.
    • Depending on the strain and case management, the fatality rates for the virus range from 24% to 88%.

    Transmission and Prevention

    • The natural carrier of the Marburg virus is the African fruit bat, which carries the virus but does not fall sick from it.
    • Human-to-human transmission occurs through contact with blood or other bodily fluids.
    • Rehydration treatment to alleviate symptoms can improve the chances of survival.

    Its outbreaks

    • The virus has caused simultaneous outbreaks of disease in laboratories in Marburg, Germany and Belgrade, Serbia in 1967, resulting in seven deaths.
    • During an outbreak in Angola in 2004, the virus killed 90% of the 252 people who were infected, and in Ghana last year, two people died of Marburg.

    What is ‘Office of Profit’?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Office of Profit

    Mains level: Read the attached story

    Central idea: Jharkhand CM’s chair remains uncertain as the Election Commission (EC) is understood to have conveyed its decision in an office-of-profit complaint against him to the Governor.

    Why in news?

    • Under Section 9A of the Representation of the People Act, 1951, the CM could face disqualification for entering into a government contract.
    • The Constitution of India does not define the Office of Profit. It has only mentioned it under Article 102 (1) and Article 191 (1).

    What is ‘Office of Profit’?

    • In India, the concept of an “Office of Profit” refers to a situation where a person holds a government position that brings them financial gain or other advantages, while at the same time they hold an elected or other public office.
    • The idea behind this concept is to prevent any conflict of interest and ensure that elected representatives do not hold positions that may compromise their independence and impartiality.

    Indian context to this

    • MPs and MLAs, as members of the legislature, hold the government accountable for its work.
    • The essence of disqualification is if legislators hold an ‘office of profit’ under the government, they might be susceptible to government influence, and may not discharge their constitutional mandate fairly.
    • The intent is that there should be no conflict between the duties and interests of an elected member.
    • Hence, the office of profit law simply seeks to enforce a basic feature of the Constitution- the principle of separation of power between the legislature and the executive.

    What governs the term?

    • At present, the Parliament (Prevention of Disqualification) Act, 1959, bars an MP, MLA or an MLC from holding any office of profit under the central or state government unless it is exempted.
    • However, it does not clearly define what constitutes an office of profit.
    • Legislators can face disqualification for holding such positions, which bring them financial or other benefits.
    • Under the provisions of Article 102 (1) and Article 191 (1) of the Constitution, an MP or an MLA (or an MLC) is barred from holding any office of profit under the Central or State government.

    An undefined term

    • The officials of the law ministry are of the view that defining an office of profit could lead to the filing of a number of cases with the Election Commission and the courts.
    • Also, once the definition is changed, one will also have to amend various provisions in the Constitution including Article 102 (1) (a) and Article 109 (1) (a) that deal with the office of profit.
    • It will have an overarching effect on all the other sections of the Constitution.

    Factors constituting an ‘office of profit’

    • The 1959 law does not clearly define what constitutes an office of profit but the definition has evolved over the years with interpretations made in various court judgments.
    • An office of profit has been interpreted to be a position that brings to the office-holder some financial gain, or advantage, or benefit. The amount of such profit is immaterial.
    • In 1964, the Supreme Court ruled that the test for determining whether a person holds an office of profit is the test of appointment.

    What is the ‘test of appointment’?

    Several factors are considered in this determination including factors such as:

    1. whether the government is the appointing authority,
    2. whether the government has the power to terminate the appointment,
    3. whether the government determines the remuneration,
    4. what is the source of remuneration, and
    5. power that comes with the position

     

    Try this MCQ:

    Q. What is an “Office of Profit” in India?

    a) A position that is controlled by the government and comes with no financial gain or other benefits.

    b) A position that is controlled by the government and comes with some financial gain or other benefits.

    c) A position that is controlled by the private sector and comes with no financial gain or other benefits.

    d) A position that is controlled by the private sector and comes with some financial gain or other benefits.

    India’s first Law Minister Dr. Ambedkar’s resignation letter missing from records

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Read the attached story

    Mains level: Social reforms stipulated by Dr. Ambedkar

    ambedkar

    Dr. BR Ambedkar was India’s first Law Minister after independence. The letter of his resignation is now missing from official records.

    Dr Ambedkar as Law Minister

    • Dr. B.R. Ambedkar served as Independent India’s first law minister.
    • He was an Indian jurist, economist, politician, and social reforme, who was posthumously awarded the Bharat Ratna in 1990.
    • It is believed that Sardar Patel and Mahatma Gandhi proposed Dr. Ambedkar’s name for the post of Law Minister in the Nehru Cabinet.

    Why was he selected for the post?

    • Being father of our Constitution: Sardar Patel, then deputy PM, had a high regard for Dr. Ambedkar’s intellectual abilities and his contributions to the drafting of India’s Constitution.
    • Political urge for inclusivity: Additionally, Dr. Ambedkar’s role in the Dalit movement and his fight against caste discrimination also made him a significant political figure.
    • Representation of the marginalized: His appointment as the Law Minister was seen as a symbol of inclusivity and representation of marginalized communities in the government.

    Why did Dr. Ambedkar resign?

    • Political differences with Nehru: He resigned as Law Minister, due to differences with the then PM, Jawaharlal Nehru, over the Hindu Code Bill. He specifically wanted to reform Hindu Personal Laws and not every personal laws in India.
    • Row over reforming Personal Laws: The bill aimed to reform Hindu personal laws related to marriage, divorce, and inheritance, but Dr. Ambedkar believed that it did not go far enough in granting women’s rights and wanted more radical changes.
    • Injustice to women: Ambedkar had proposed a more comprehensive set of reforms that would have given women greater rights in matters such as property ownership and inheritance, but his proposals were met with resistance from Nehru and other members of the government.

    Efforts to locate his resignation letter

    • The letter was not found in the National Archives of India and the Ministry of Home Affairs.
    • The Maharashtra government has also been unable to locate the letter in its archives.
    • RTI (Right to Information) requests were also unsuccessful.

    Significance of his letter

    • The missing letter is a matter of concern as it is an important historical document.
    • Ambedkar’s resignation was a significant event in India’s political history and the reasons behind it are still relevant today.
    • The letter could shed light on the differences between the visionary Dr. Ambedkar and then mainstream politicians.

    Scientists discover new ‘Quasicrystals’

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Quasicrystals

    Mains level: NA

    quasicrystals

    Scientists have discovered a new type of quasicrystal, one with 12-fold symmetry, in the Sand Hills of north central Nebraska, USA.

    What is a Quasicrystal?

    • Quasicrystal is essentially a crystal-like substance.
    • However, unlike a crystal, in which atoms are arranged in a repeating pattern, a quasicrystal consists of atoms that are arranged in a pattern that doesn’t repeat itself regularly.
    • For the longest time, physicists believed every crystalline arrangement of atoms must have a pattern that repeats itself perfectly over and over again.
    • However, this changed in 1982, when material scientist Dan Shechtman discovered crystal structures that are mathematically regular, but that do not repeat themselves.

    How are they formed?

    • Electrical discharge triggered quasicrystal formation in the recent finding.
    • It’s also the first time that researchers have found a quasicrystal somewhere other than meteorites or the debris from nuclear blasts.

    Applications of quasicrystals

    • There is no major commercial applications yet exploit properties of the quasicrystalline state directly.
    • Quasicrystals form in compounds noted for their high strength and light weight, suggesting potential applications in aerospace and other industries.
    • They can be used in surgical instruments, LED lights and non-stick frying pans.

    Prelims level: Agasthyarkoodam Observatory

    Mains level: NA

    agasthyarkoodam

    Agasthyarkoodam was once home to a forgotten and long-lost 19th-century observatory established by Scottish meteorologist John Allan Broun.

    Agasthyarkoodam Observatory

    • The Agasthyarkoodam Observatory is an astronomical research observatory located in the state of Kerala.
    • The observatory is situated at an altitude of 1600 meters above sea level and is owned and operated by the Indian Institute of Astrophysics (IIA).
    • The observatory is equipped with a 1-meter optical telescope and various other instruments for studying the night sky.
    • The observatory is used for research and educational purposes and is open to the public for viewing night-sky objects.

    Why in news?

    • Agasthyarkoodam in the Western Ghats once housed a magnetic observatory that was established by Scottish meteorologist John Allan Broun.
    • Broun used it to record magnetic and meteorological observations in tandem with the Thiruvananthapuram astronomical observatory.
    • Broun’s astronomical research in India began after he was invited by the ruler of the erstwhile Travancore Uthram Tirunal Marthanda Varma to helm the Thiruvananthapuram observatory following the death of its first director John Caldecott in 1849.
    • The observatory started recording observations in July 1855.
    • However, it was closed in 1881 by the then Madras Governor Sir William Denison.

    What are magnetic observatories?

    • Magnetic observatories continuously measure and record Earth’s magnetic field at a number of locations.
    • In an observatory of this sort, magnetized needles with reflecting mirrors are suspended by quartz fibres.
    • Light beams reflected from the mirrors are imaged on a photographic negative mounted on a rotating drum.
    • Variations in the field cause corresponding deflections on the negative.
    • Their magnetograms are photographed on microfilm and submitted to world data centres, where they are available for scientific or practical use.

    From UPSC perspective, the following things are important:

    Prelims level: Solar Prominence

    Mains level: Not Much

    solar

    Recently, the sun puzzled many scientists with a large prominence near its north pole.

    What is Solar Prominence?

    • A solar prominence (also known as a filament when viewed against the solar disk) is a large, bright feature extending outward from the Sun’s surface.
    • Prominences are anchored to the Sun’s surface in the photosphere, and extend outwards into the Sun’s hot outer atmosphere, called the corona.
    • A prominence forms over timescales of about a day, and stable prominences may persist in the corona for several months, looping hundreds of thousands of miles into space.

    How are they formed?

    • Scientists are still researching how and why prominences are formed.
    • The red-glowing looped material is plasma, a hot gas comprised of electrically charged hydrogen and helium.
    • The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun’s internal dynamo.
    • An erupting prominence occurs when such a structure becomes unstable and bursts outward, releasing the plasma.

    Today in History: Treaty of Alinagar

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Treaty of Alinagar

    Mains level: Not Much

    alinagar

    Signed on February 9, 1757, the Treaty of Alinagar between the Nawab of Bengal and the East India Company raised the curtains for British colonial expansion in India.

    Treaty of Alinagar, 1757

    • Signed on February 9, 1757, the Treaty of Alinagar was signed between Robert Clive of the East India Company and Mirza Muhammad Siraj Ud Daula, then Nawab of Bengal.
    • It is said to be one of the key events leading up to the Battle of Plassey later that year.
    • Plassey was where the English laid a significant blow, defeating the nawab. It paved the way for the East India Company’s takeover of Bengal.
    • The name Alinagar was a short-lived reference to modern-day Kolkata, and the treaty came about after the nawab was faced with both the British and Afghan forces.
    • He compromised with the former; however, the peace was short-lived.

    British advent in India: A quick backgrounder

    • After the Anglo-Mughal War which took place between 1686 and 1690, the British began consolidating their presence in the subcontinent.
    • It had established the Fort St. George in what was Madras, Fort William in then Calcutta and Bombay Castle by the beginning of the 18th century.
    • The British initially helped local princes and nawabs quell uprisings or revolts and they, in turn, gave them concessions.

    Course of the treaty

    • In January 1757, the British attacked the town of Hooghly, close to then Calcutta, with over 700 men.
    • The Nawab of Bengal, Siraj-ud-daulah, who had just come to power a year earlier in his early 20s, mobilised forces.
    • His troops would overpower the British and reach Calcutta on January 10, 1757, having lost over 600 men.
    • However, the losses sustained in the war had resulted in the nawab losing confidence.
    • He signed what came to be known as the Treaty of Alinagar with Robert Clive – who became the first British Governor of the Bengal Presidency – on February 9, 1757.
    • Siraj-ud-daulah agreed to the restoration of the company’s factories and allowed for the fortification of Calcutta.

    Aftermath of the battle

    • The British then moved on to wrest the remaining territories in Bengal from the French, laying siege to Chandannagar.
    • However, the move did not go down well with the nawab.
    • But, Daulah was also wary of Afghan forces under Ahmad Shah Durrani and the Marathas.
    • Traders in his kingdom were already wary of him and there was a conspiracy led by the likes of his military general, Mir Jafar.
    • Events would later culminate in the Battle of Plassey on June 23, 1757.
    • It resulted in the East India Company gaining hold of Bengal and was a significant event in its rise to power in the subcontinent.

  • Russian Invasion of Ukraine: Global Implications

    US bombed Nord Stream Gas Pipeline

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Nord Stream Pipelines

    Mains level: Not Much

    nord

    An American investigative journalist has claimed that the September 2022 bombing of the undersea Nord Stream gas pipelines was carried out by the US Central Intelligence Agency (CIA).

    What is Nord Stream Pipeline?

    (1) Nord Stream 1:

    • Nord Stream 1 is the biggest pipeline transporting natural gas between Russia and Europe via Germany.
    • It is a system of offshore natural gas pipelines running under the Baltic Sea from Russia to Germany.
    • Nord Stream 1 is a 1,224 km underwater gas pipeline that runs from Vyborg in northwest Russia to Lubmin in northeastern Germany via the Baltic Sea.

    (2) Nord Stream 2:

    • Russian threats to choke this gas supply to Europe present an economic threat to Germany.
    • To expand options and double the supply from Russia, Germany decided to build Nord Stream 2.
    • The construction of the $11 billion-worth Nord Stream 2 was completed in 2021 but never began commercial operations.

    Why the Nord Stream pipeline is so much in news?

    • For Germany: Energy prices in Germany, Europe’s largest economy, are among the lowest in the continent because of the cheap gas supplies via Nord Stream 1. This also makes German manufactured goods more competitive in the international market.
    • For European Union: In 2021, Russia supplied nearly 40 per cent of the EU’s natural gas needs through this pipeline. The flows through Nord Stream play a vital role in filling up the national storage tanks of EU. It is crucial to provide the required heating in the upcoming winter.
    • For Russia: Russia is using the supplies via the crucial pipeline as a bargain to navigate its economy through sanctions from the western countries.

    What is the current status of Nord Stream Pipeline?

    • Nord stream pipeline is the largest single supply route for Russian gas to Europe. The Russian state owned gas company Gazprom has a majority ownership in the pipeline.
    • While it was running at just 20% of its capacity since the Russia-Ukraine conflict began, the company, in early September fully cut gas flows from the pipeline on the pretext of maintenance.
    • According to Bloomberg, while 40% of Europe’s pipeline gas came from Russia before Russia Ukraine the war, the number now stands at just 9%.
    • Even though both pipelines were not running commercially, they had millions of cubic metres of gas stored in them.

    • It will be a four stage launching vehicle.
    • The first three stages will use Hydroxyl-terminated polybutadiene (HTPB) based solid propellant, with a fourth terminal stage being a Velocity-Trimming Module (VTM).

    SSLV vs. PSLV: A comparison

    • The SSLV was developed with the aim of launching small satellites commercially at drastically reduced price and higher launch rate as compared to Polar SLV (PSLV).
    • The projected high launch rate relies on largely autonomous launch operation and on overall simple logistics.
    • To compare, a PSLV launch involves 600 officials while SSLV launch operations would be managed by a small team of about six people.
    • The launch readiness period of the SSLV is expected to be less than a week instead of months.
    • The SSLV can carry satellites weighing up to 500 kg to a low earth orbit while the tried and tested PSLV can launch satellites weighing in the range of 1000 kg.
    • The entire job will be done in a very short time and the cost will be only around Rs 30 crore for SSLV.

    Significance of SSLV

    • SSLV is perfectly suited for launching multiple microsatellites at a time and supports multiple orbital drop-offs.
    • The development and manufacture of the SSLV are expected to create greater synergy between the space sector and private Indian industries – a key aim of the space ministry.
