GK One-Liners

What: Professor Jainendra K. Jain has become the first person of Indian origin to receive the Wolf Prize in Physics, one of the most prestigious awards in science (often called a precursor to the Nobel Prize). The 2025 Wolf Prize in Physics was awarded for his discovery of Composite Fermions, a theoretical concept that provides the definitive explanation for the Fractional Quantum Hall Effect (FQHE). He shared the prize with James P. Eisenstein (USA) and Mordehai Heiblum (Israel). The award ceremony was held at the Knesset (Israeli Parliament) in Jerusalem.

How: The FQHE is a quantum mechanical phenomenon observed in two-dimensional electron systems subjected to strong magnetic fields and low temperatures, where electrons behave collectively to produce fractional electrical conductance. Jain’s Composite Fermion theory (proposed in 1989) explained this by showing that electrons, under extreme conditions, pair with magnetic flux quanta to form new quasi-particles called composite fermions — elegantly unifying a wide range of FQHE observations. Prof. Jain is the Founding Director of the Lakshmi Teja Physics Institute (LTPI), Mumbai.

Why: The Wolf Prize is awarded by the Wolf Foundation (Israel) since 1978 across six fields. This is a landmark for Indian science on the global stage. UPSC and state PSC exams regularly test Wolf Prize winners, particularly Indian-origin recipients. Key facts: Wolf Prize founded 1978, awarded at Knesset, FQHE discovered by Tsui-Störmer-Laughlin (Nobel 1998), Jain’s composite fermion theory 1989.

What: Chennai Petroleum Corporation Limited (CPCL) has been upgraded to Navratna status, making it India’s 28th Navratna Central Public Sector Enterprise (CPSE). Previously a Miniratna Category-I CPSE, CPCL’s upgrade was approved by Finance Minister Nirmala Sitharaman under the Department of Public Enterprises (DPE), Ministry of Finance. CPCL recorded a turnover of Rs 59,400 crore in FY 2025–26.

How: India’s CPSE classification system has three tiers: Maharatna (highest), Navratna (middle), and Miniratna (Category-I and II). Navratna status grants a CPSE significantly enhanced financial and operational autonomy — crucially, the ability to invest up to Rs 1,000 crore per project without seeking government approval (compared to Rs 500 crore for Miniratna Cat-I). This status is awarded based on financial performance, including turnover, net profit, and net worth.

Why: CPSE classification is a high-yield topic for UPSC Prelims, SSC CGL, and banking exams. Key thresholds to remember: Maharatna can invest up to Rs 5,000 crore per project; Navratna up to Rs 1,000 crore; Miniratna Cat-I up to Rs 500 crore. CPCL is a subsidiary of Indian Oil Corporation (IOC) and operates refineries in Tamil Nadu. Watch for total Navratna count (now 28) as it changes with upgrades.

What: Rajendra Kumar Saboo, currently serving as Executive Director (ED) of UCO Bank, has been given additional charge as Managing Director (MD) & Chief Executive Officer (CEO) of UCO Bank. He assumed charge on June 19, 2026, and will serve in this capacity until August 31, 2026. He succeeds Ashwani Kumar, whose tenure as MD & CEO ended on May 31, 2026. The appointment was approved by the Department of Financial Services (DFS), Ministry of Finance.

How: Appointments to the top executive positions in public sector banks (PSBs) are made through the Banks Board Bureau (BBB) — an autonomous body under the Ministry of Finance — which recommends candidates to the government. For interim or additional-charge appointments (as in this case), the DFS directly approves the arrangement until a regular appointment is formalised. UCO Bank is headquartered in Kolkata and is a public sector bank under the ownership of the Government of India.

Why: Banking sector appointments are a staple in IBPS PO, IBPS Clerk, SBI PO, and RBI Grade B general awareness sections. For UCO Bank specifically, remember: HQ in Kolkata, PSB under MoF, and appointments routed through DFS/BBB. The “additional charge” mechanism is commonly tested as it applies whenever a regular appointment is pending — a frequently recurring pattern in Indian PSB governance.

What: The Insurance Regulatory and Development Authority of India (IRDAI) has constituted an Artificial Intelligence (AI) Working Group (WG-AI) to assess AI adoption across the insurance sector and recommend a comprehensive AI governance framework. The group is chaired by Prof. Sandeep K. Shukla, Director of the Indian Institute of Information Technology (IIIT) Hyderabad, and comprises 7 members. The member-convener is Deepak Gaikwad, General Manager (GM) and Chief Information Security Officer (CISO) of IRDAI. The group is mandated to submit its report within 3 months.

How: The WG-AI will evaluate how AI technologies — including machine learning, generative AI, and automated underwriting tools — are being used by insurance companies for claims processing, fraud detection, customer onboarding, and risk assessment. It will then design guardrails covering transparency, accountability, data privacy, and algorithmic fairness specifically for India’s insurance sector, benchmarking global regulatory approaches.

Why: IRDAI is the apex regulator for India’s insurance sector (established 1999, HQ Hyderabad). This initiative reflects the broader push under India’s National AI Mission to embed responsible AI across regulated financial sectors. For UPSC and banking exams, IRDAI’s composition, mandate, and major policy decisions are high-frequency topics. AI governance in BFSI (Banking, Financial Services, and Insurance) is also a hot theme for mains essay and interview.

What: The men’s javelin throw event at the 2026 Doha Diamond League was held on June 19, 2026, at Suhaim bin Hamad Stadium, Doha, Qatar. Rumesh Tharanga Pathirage of Sri Lanka won with a throw of 88.68 m. Anderson Peters (Grenada) finished 2nd (86.38 m), Curtis Thompson (USA) 3rd (85.99 m), and Neeraj Chopra (India) finished 4th with 85.69 m. The Diamond League is the premier annual athletics circuit organised by World Athletics.

How: The Diamond League consists of a series of one-day track and field meetings held across major global cities. Athletes earn points across the season leading to Diamond League Finals. Neeraj Chopra — the 2020 Tokyo Olympics gold medallist and 2024 Paris Olympics silver medallist — is India’s most prominent figure in athletics. His 4th place finish here, while below the podium, reflects a competitive global javelin field where throws of 85+ m are common at elite level.

Why: Neeraj Chopra-related questions appear regularly in sports GK for all competitive exams. Key facts to retain: Tokyo 2020 gold (87.58 m), Paris 2024 silver (89.45 m), World Championships 2023 gold. The Diamond League format, venue names, and winners are tested in SSC, UPSC, and state PSC current affairs sections. Watch for any subsequent competitions where Chopra may improve his standings in the 2026 season.

What: The Government of Maharashtra signed a Letter of Intent (LoI) with Google for Education at Mantralaya, Mumbai, to train over 4 lakh (400,000) school teachers in Artificial Intelligence (AI) and digital technology. The LoI was signed by Dadaji Bhuse, Maharashtra’s School Education Minister. Training will be conducted over 18 months, is free of cost, and will be delivered in Marathi, Hindi, and English to ensure accessibility across the state’s diverse teacher workforce.

How: The programme will be implemented through Google’s AI Educator Series, which trains Master Trainers who then cascade training to larger groups of teachers — a train-the-trainer model. The initiative aligns with the National Education Policy (NEP) 2020, which mandates technology integration and 21st-century skills across school education. Master trainers will be certified and equipped to deliver AI literacy modules at the district and school level.

Why: This initiative sits at the intersection of EdTech, NEP 2020 implementation, and state-level digital governance — all high-yield areas for UPSC Mains GS-II (governance, education policy) and state PSC exams. For Maharashtra-specific exams, the Mantralaya venue and Dadaji Bhuse as signatory are key details. The free-of-cost, multilingual delivery model is noteworthy as a benchmark for AI skilling at scale.
