  • Project Udbhav: Rediscovering India’s Strategic Heritage for Modern Defense

    udbhav

    Central Idea

    • The Indian Army has launched Project Udbhav, an initiative aimed at rediscovering the profound heritage of statecraft and strategic thinking from ancient Indian texts.

    Project Udbhav

    • Project Udbhav is conducted in collaboration by Indian Army and the United Service Institution of India, a defense think-tank.
    • The primary goal is to comprehend the depths of indigenous military systems, their evolution, enduring strategies, and the strategic thought processes that have shaped the Indian subcontinent for millennia.
    • It delves into India’s rich historical narratives in the domains of statecraft and strategic thinking.
    • It encompasses indigenous military systems, historical texts, regional texts, kingdoms, thematic studies, and Kautilya Studies.

    Why such move?

    • The initiative underscores the Indian Army’s recognition of India’s ancient wisdom in statecraft, strategy, diplomacy, and warfare.
    • It seeks to establish a connection between historical wisdom and contemporary needs.

    Scholarly Outcomes and Ongoing Research

    • A study to compile Indian stratagems based on ancient texts has been ongoing since 2021.
    • A book listing 75 aphorisms selected from ancient texts has already been published under the initiative.
    • The first scholarly outcome is the 2022 publication titled “Paramparik Bhartiya Darshan…Ranniti aur Netriyta ke Shashwat Niyam,” which is meant to be read by all ranks of the Indian Army.
    • A recent panel discussion included a dialogue on the study of ancient texts ranging from the 4th century BCE to the 8th century CE, with a specific focus on Kautilya, Kamandaka, and the Kural.

  • Story of Mahatma Gandhi’s Portrait on Indian Banknotes

    gandhi

    Central Idea

    • Mahatma Gandhi seems a natural choice for the face of Indian currency as the Father of the Nation.
    • This wasn’t until 1996 that his image became a permanent fixture on legal banknotes issued by the RBI, the nation’s central bank and regulatory authority for the Indian banking system.

    Gandhi’s Portrait on Indian Currency

    • Photographic Source: The portrait of Gandhi on Indian banknotes is not a caricature but a cut-out from a 1946 photograph featuring him alongside British politician Lord Frederick William Pethick-Lawrence.
    • Expression Matters: This particular photograph was chosen for its ideal depiction of Gandhi’s smiling visage, and the portrait is a mirrored image of the cut-out.
    • Unknown Photographers: Interestingly, the identities of the photographer of this image and the person who selected it remain unknown.

    Currency Design Process

    • RBI’s Responsibility: The RBI’s Department of Currency Management is tasked with designing rupee notes, subject to approval from the central bank and the Union government.
    • Regulatory Framework: Section 25 of the RBI Act, 1934, mandates that the design, form, and material of banknotes must be approved by the central government after considering the central board’s recommendations.

    Gandhi’s Debut on Indian Currency

    • 1969 Commemoration: Gandhi made his first appearance on Indian currency in 1969 through a special series issued to commemorate his 100th birth anniversary. These notes, featuring Gandhi alongside the Sevagram Ashram, bore the signature of RBI governor LK Jha.
    • 1987 Inclusion: In October 1987, a series of Rs 500 currency notes featuring Gandhi was introduced.

    The Transition to Independent India’s Banknotes

    • Post-Independence Currency: Initially, after India gained independence in August 1947, the RBI continued to issue notes from the colonial era that depicted King George VI.
    • Symbol Selection: The government of India introduced new 1-rupee notes in 1949, replacing King George with a representation of the Lion Capital of Ashoka Pillar at Sarnath.
    • Design Continuity: The subsequent release of banknotes in 1950, in denominations of Rs 2, 5, 10, and 100, featured the Lion Capital watermark, maintaining continuity with earlier designs.

    Gandhi’s Permanence on Banknotes

    • Security Concerns in the 1990s: By the 1990s, the RBI recognized the need for enhanced security features on currency notes due to advancements in reprographic techniques. A human face was deemed less susceptible to forgery than inanimate objects.
    • Gandhi’s Enduring Appeal: Mahatma Gandhi’s national significance made him the ideal choice. In 1996, the RBI introduced a new ‘Mahatma Gandhi Series’ of banknotes, replacing the previous Ashoka Pillar notes and incorporating advanced security features.
    • Continuity in 2016: The ‘Mahatma Gandhi New Series’ of banknotes, introduced in 2016, continued to feature Gandhi’s portrait, with the addition of the Swachh Bharat Abhiyan logo and enhanced security elements.

    Other Suggestions for Currency Faces

    • Varied Proposals: Over the years, there have been calls to feature different personalities on banknotes apart from Gandhi.
    • Lord Ganesha and Goddess Lakshmi: In October 2022, Delhi Chief Minister Arvind Kejriwal appealed to the Prime Minister and the Union government to include images of Lord Ganesha and goddess Lakshmi on currency notes.
    • Previous Proposals: Suggestions in the past included Noble Laureate Rabindranath Tagore and former President APJ Abdul Kalam. However, the RBI and Indian authorities have consistently upheld Gandhi’s representation, considering him the most fitting embodiment of India’s ethos.

    Conclusion

    • Gandhi’s Enduring Legacy: Mahatma Gandhi’s presence on Indian currency notes stands as a testament to his indelible impact on the nation’s history and values.
    • Challenges to Change: While various proposals have emerged over the years, the symbolism and significance of Gandhi on banknotes remain unwavering, reflective of his towering stature in India’s collective consciousness.

    pmi manager

    Central Idea

    • Surge in PMI to 31-month high: The S&P Global India Manufacturing PMI soared to 58.7 in May, the highest level in 31 months.

     

    Service Sector

    The service sector, also known as the tertiary sector, includes a wide range of economic activities that are focused on providing intangible goods and services to customers.

    Some examples of activities that fall under the service sector include:

    1. Hospitality and tourism: This includes activities such as hotels, restaurants, travel agencies, and tour operators.
    2. Retail and wholesale trade: This includes businesses that buy and sell goods, such as supermarkets, department stores, and online retailers.
    3. Financial services: This includes banks, insurance companies, and investment firms.
    4. Professional and business services: This includes activities such as legal services, accounting, consulting, and advertising.
    5. Information and communication technology: This includes activities such as software development, telecommunications, and data processing.
    6. Healthcare and social assistance: This includes activities such as hospitals, clinics, nursing homes, and social services.
    7. Education and training: This includes activities such as schools, colleges, universities, and vocational training.
    8. Transportation and logistics: This includes activities such as shipping, warehousing, and distribution.

    Purchasing Managers’ Index (PMI)

    • PMI is an indicator of business activity — both in the manufacturing and services sectors.
    • The S&P Global India Services PMI is compiled by S&P Global from responses to questionnaires sent to a panel of around 400 service sector companies.
    • It is a survey-based measure that asks the respondents about changes in their perception of some key business variables from the month before.
    • It is calculated separately for the manufacturing and services sectors and then a composite index is constructed.

    How is the PMI derived?

    • The PMI is derived from a series of qualitative questions.
    • Executives from a reasonably big sample, running into hundreds of firms, are asked whether key indicators such as output, new orders, business expectations and employment were stronger than the month before and are asked to rate them.

    How does one read the PMI?

    • A figure above 50 denotes expansion in business activity. Anything below 50 denotes contraction.
    • Higher the difference from this mid-point greater the expansion or contraction. The rate of expansion can also be judged by comparing the PMI with that of the previous month data.
    • If the figure is higher than the previous month’s then the economy is expanding at a faster rate. If it is lower than the previous month then it is growing at a lower rate.

    Key insights of recent trend

    • Fastest factory order growth: Factory orders rose at the fastest pace since January 2021.
    • Unprecedented accumulation of inputs: Producers accumulated inputs at an unprecedented pace due to lower costs.
    • Improvement in operating conditions: The index reflects a substantial improvement in operating conditions, with a significant increase from 57.2 in April.
    • Strong growth in order books and exports: Order books grew for the 23rd consecutive month, supported by a rise in export deals.
    • Highest output levels in 28 months: Output levels reached the highest point in 28 months.
    • Increased hiring: Pressure on capacities led firms to increase hiring, reaching a six-month high.

    Reasons behind this rise

    • Rise in selling prices: Producers raised selling prices at a solid and quicker rate in May, the highest in a year.
    • Mild input costs but adjusted charges: Input costs remained historically mild, but producers adjusted their charges due to sustained cost increases and a supportive demand environment.
    • Improved business confidence: Business confidence about growth improved, reaching a five-month high.
    • Public faith in economy: Factors such as publicity and demand resilience contributed to the optimistic outlook.

    Why discuss this?

    • Passwords have become nearly synonymous with cybersecurity in the 21st century, albeit with an unsavory connotation.
    • Despite efforts to promote robust password practices, “password” and “123456” continue to dominate the list of common passwords, underscoring the pervasive vulnerability of most accounts.

    Passkeys: Need for Change

    • Ineffectiveness of Passwords: The prevailing authentication method, based on passwords, falls short in ensuring adequate security.
    • Big Tech Solution: In response to this predicament, major tech companies propose a solution – passkeys.

    Understanding Passkeys

    • Web Authentication Standard: Passkeys are a security feature built on the WebAuthentication (WebAuthn) standard.
    • Public-Key Cryptography: Passkeys employ public-key cryptography, a potent technique employing a public key (server-side) and a private key (user-side).
    • Authentication Process: When users log in, a challenge is sent to their device, which utilizes the private key to solve it and respond. The server then validates the response with the public key, all without storing any secrets, enhancing security.

    Getting Started with Passkeys

    • Wide Compatibility: Leading tech companies, including Microsoft, Google, and Apple, have collaborated to make passkeys accessible to most recent phones and PCs.
    • Operating Systems: Passkeys are available on iOS 16+, iPadOS 16+, macOS Ventura, Android 9+, Windows 10, and Windows 11.
    • Web Browsers: Passkeys are supported on popular browsers like Chrome, Edge, Safari, and Firefox.

    Creating and Using Passkeys

    • Account Requirement: Users need an account with a provider supporting passkeys, such as Microsoft, Google, or Apple.
    • Activation Process: To enable passkeys, sign in to a compatible app or website, activate the passkey option, and obtain a unique passkey linked to your account and device.
    • Usage: Passkeys can be used with biometrics (e.g., Touch ID, Face ID), QR codes, or device verification.

    Future of Passwords

    • Inevitable Evolution: While passkeys offer notable advantages over traditional passwords in terms of security and user-friendliness, they still face challenges related to compatibility and user adoption.
    • Industry Push: Notably, Google, Apple, and Microsoft are driving the passkey agenda strongly, suggesting that passwords may eventually become obsolete.

    Conclusion

    • A Security Evolution: The emergence of passkeys as an alternative to traditional passwords marks a significant shift in the realm of cybersecurity.
    • Ongoing Transition: As passkeys gain momentum and garner support from tech giants, they may gradually pave the way for a password-free future, promising enhanced security and user convenience in the digital realm.

  • Lesser-Known Facets of Bhagat Singh’s Life

    bhagat singh

    Central Idea

    • Bhagat Singh, born on September 28, 1907, in the village of Banga (now in Faisalabad, Pakistan), is celebrated as a charismatic revolutionary who sacrificed his life for the cause of Indian independence at the young age of 23.

    Five Lesser-Known Aspects of Bhagat Singh’s Life

    [1] A Family of Progressive Freedom Fighters

    • Anti-Colonial Roots: Bhagat Singh’s father, Kishan, and uncle, Ajit, were actively involved in anti-British activities. Kishan faced imprisonment in 1910 for disseminating seditious literature, while Ajit was deported to Mandalay in 1907 for his inflammatory speeches against the Punjab Colonisation Bill. Both played significant roles in the freedom struggle, influencing Bhagat Singh’s upbringing in an anti-colonial environment.
    • Dissent within the Family: Despite the family’s strong anti-British stance, Bhagat Singh publicly criticized his father for submitting a mercy plea to the Viceroy when he and other revolutionaries faced the gallows, revealing his unwavering commitment to the revolutionary cause.

    [2] A Scholar and Writer

    • Prolific Writer: Bhagat Singh contributed to Urdu and Punjabi newspapers in Amritsar during the 1920s and authored pamphlets and ‘seditious’ literature condemning British colonial rule.
    • Eclectic Reading: His jail notebooks revealed his interests extended beyond politics, encompassing literature from renowned poets and writers, including Rabindranath Tagore, William Wordsworth, Wajid Ali Shah, Mirza Ghalib, and Iqbal.

    [3] An Atheist and Marxist with Anarchist Leanings

    • Religious Critique: Bhagat Singh was an avowed atheist who criticized religion in his essay ‘Why I am an Atheist’ (1930), rejecting the concept of one true religion. He viewed religious beliefs as divisive and demoralizing.
    • Inspirations: Bhagat Singh drew inspiration from Marxist thinkers such as Marx, Lenin, Trotsky, and Bakunin. In his final testament, ‘To Young Political Workers’ (1931), he advocated for “social reconstruction on new, i.e., Marxist, basis.” However, he did not fully align with orthodox Marxist views, particularly on authoritarianism.

    [4] Support from Jinnah

    • Jinnah’s Defense: While Mahatma Gandhi refrained from intervening in Bhagat Singh’s trial, MA Jinnah ardently defended him. Jinnah vehemently opposed a proposed Bill that would have allowed trials in absentia, delivering a compelling speech in the Central Assembly in 1929.
    • Successful Opposition: Jinnah’s staunch stance led to the foiling of the attempt to pass the law, but Bhagat Singh’s trial continued under dubious circumstances, resulting in his death sentence in 1930.

    [5] Jawaharlal Nehru’s Support

    • Nehru’s Critique: Jawaharlal Nehru criticized the British legal process and the injustice inflicted on Bhagat Singh. He admired Bhagat Singh’s courage and self-sacrifice.
    • Historic Visit: Nehru, along with other leaders like Subhash Chandra Bose, visited Bhagat Singh in prison. Despite their differences in methods, Nehru’s respect for Bhagat Singh remained unwavering.
    • Congress Resolution: After Bhagat Singh’s execution, Nehru moved an official resolution in a Congress session, condemning the execution and demanding commutation, even though the Congress officially rejected violence as a means of achieving independence.

  • India’s Current Account Deficit (CAD) Widens: Implications and Outlook

    Central Idea

    • Data released by the Reserve Bank of India (RBI) reveals that India’s Current Account Deficit (CAD) expanded significantly to $9.2 billion, equivalent to 1.1% of GDP, during the April-June quarter.
    • This represents a substantial increase from the preceding three months when it stood at $1.3 billion, or 0.2% of GDP.
    • Contrasting with the year-earlier quarter of fiscal 2022-23, where the CAD was $17.9 billion (2.1% of GDP), the current scenario reflects evolving economic dynamics.

    What is Current Account Deficit (CAD)?

    • A current account is a key component of balance of payments, which is the account of transactions or exchanges made between entities in a country and the rest of the world.
    • This includes a nation’s net trade in products and services, its net earnings on cross border investments including interest and dividends, and its net transfer payments such as remittances and foreign aid.
    • A CAD arises when the value of goods and services imported exceeds the value of exports, while the trade balance refers to the net balance of export and import of goods or merchandise trade.

    Components of Current Account

    Current Account Deficit (CAD) =  Trade Deficit + Net Income + Net Transfers

    (1) Trade Deficit

    • Trade Deficit = Imports – Exports
    • A Country is said to have a trade deficit when it imports more goods and services than it exports.
    • Trade deficit is an economic measure of a negative balance of trade in which a country’s imports exceeds its exports.
    • A trade deficit represents an outflow of domestic currency to foreign markets.

    (2) Net Income

    • Net Income = Income Earned by MNCs from their investments in India.
    • When foreign investment income exceeds the savings of the country’s residents, then the country has net income deficit.
    • This foreign investment can help a country’s economy grow. But if foreign investors worry they won’t get a return in a reasonable amount of time, they will cut off funding.
    • Net income is measured by the following things:
    1. Payments made to foreigners in the form of dividends of domestic stocks.
    2. Interest payments on bonds.
    3. Wages paid to foreigners working in the country.

    (3) Net Transfers

    • In Net Transfers, foreign residents send back money to their home countries. It also includes government grants to foreigners.
    • It Includes Remittances, Gifts, Donation etc

    How does Current Account Transaction takes place?

    • While understanding the Current Account Deficit in detail, it is important to understand what the current account transactions are.
    • Current account transactions are transactions that require foreign currency.
    • Following transactions with from which component these transactions belong to :
    1. Component 1 : Payments connection with Foreign trade – Import & Export
    2. Component 2 : Interest on loans to other countries and Net income from investments in other countries
    3. Component 3 : Remittances for living expenses of parents, spouse and children residing abroad, and Expenses in connection with Foreign travel, Education and Medical care of parents, spouse and children

    What are the reasons for the current account deficit?

    deficit

    • Intensifying geopolitical tensions and supply chain disruptions leading to crude oil and commodity prices soaring globally have been exerting upward pressure on the import bill.
    • A rise in prices of coal, natural gas, fertilizers, and edible oils have added to the pressure on trade deficit.
    • However, with global demand picking up, merchandise exports have also been rising.

    How will a large CAD affect the economy?

    • A large CAD will result in the demand for foreign currency rising, thus leading to depreciation of the home currency.
    • Nations balance CAD by attracting capital inflows and running a surplus in capital accounts through increased foreign direct investments (FDI).
    • However, worsening CAD will put pressure on the inflow under the capital account.
    • Nevertheless, if an increase in the import bill is because of imports for technological upgradation it would help in long-term development.

  • Alzheimer’s Research: Mystery of Brain Cell Death

    brain cell

    Central Idea

    • Scientists have long sought medical treatments for Alzheimer’s disease but have faced limited success.
    • The approval of the drug Lecanemab by the US FDA in 2023 has brought renewed optimism, as it shows promise in slowing the progression of Alzheimer’s in its early stages.

    How brain cells die?

    • Revealing the Connection: Researchers from Belgium and UK have shed light on the connection between abnormal proteins (amyloid and tau) and a process called necroptosis, which leads to cell death.
    • Cell Death Mechanism: Necroptosis is a form of cell death typically triggered by immune responses to infection or inflammation, serving to eliminate damaged cells.
    • Inflammatory Response: The study suggests that in Alzheimer’s patients, amyloid protein entering brain neurons triggers inflammation and alters the internal chemistry of the cells. Amyloid forms plaques, while tau forms tangles.
    • MEG3 Molecule: When amyloid and tau processes occur simultaneously, brain cells produce a molecule called MEG3, which appears to be linked to cell death.
    • Blocking MEG3: The researchers experimented by blocking the MEG3 molecule and found that brain cells survived when this molecule was inhibited.
    • Experimental Approach: Human brain cells were transplanted into genetically modified mice that produced significant amyloid, allowing researchers to make these groundbreaking observations.

    Hope for Alzheimer’s Treatment

    • Historic Discovery: Researchers highlighted that this discovery marks the first time, after several decades of speculation, that scientists have found a plausible explanation for cell death in Alzheimer’s patients.
    • Path to New Medicines: Some are optimistic that their findings will pave the way for new medical treatments targeting Alzheimer’s.
    • Lecanemab’s Target: Lecanemab, a drug that specifically targets the amyloid protein, aligns with the potential to block the MEG3 molecule, offering the prospect of halting brain cell death in Alzheimer’s disease.

    Understanding Brain’s Complex Processes

    • Brain’s Enigma: The development of Alzheimer’s drugs has been hampered by a lack of understanding of the disease’s mechanisms within the brain.
    • Amyloid and Tau: Amyloid and tau proteins are known to accumulate in the brain of Alzheimer’s patients, but their precise roles and how they contribute to cell death remained unclear.

    Alzheimer’s Global Challenge

    • Widespread Impact: Approximately 55 million people worldwide are affected by various forms of dementia, with Alzheimer’s being one of the prominent diseases.
    • Disproportionate Burden: Two-thirds of dementia cases are found in developing countries, and with the aging global population, projections indicate that the number of dementia cases could reach 139 million by 2050, with China, India, Latin America, and Sub-Saharan Africa facing the greatest challenges.
