Nuclear energy often sparks debate, is generally considered unsafe. But very few people realize its significant role in protecting the environment and saving lives as well, apart from many other advantages. Just for information, since 1979, nuclear power has helped prevent more than 1.8 million deaths. This is by way of reducing harmful pollution from coal-fired power plants. This CLEAN ENERGY source offers a path to cleaner air, less pollution, and a safer future. As the wor

As per recent Times of India News Report entitled “Proposed nuclear power project by state sparks fresh concerns in Uttara Kannada”. My comments are as below: The recent developments like this clearly show that while India is moving forward in nuclear energy, public concerns and local engagement cannot be ignored. Progress must be accompanied by transparency, dialogue, and trust-building at the grassroots and basic level. India is making rapid achievement in nuclear energy (r

अंतरराष्ट्रीय खगोल विज्ञान दिवस दुनिया भर में मनाया जाता है। इसका उद्देश्य लोगों में खगोल विज्ञान के प्रति रुचि बढ़ाना है। यह किसी एक तय तारीख को नहीं होता। इसे साल में दो बार मनाया जाता है, एक बार वसंत में और एक बार शरद ऋतु में। यह दिन ऐसे शनिवार को चुना जाता है जो प्रथम चतुर्थी चंद्रमा के पास हो, ताकि आकाश को आसानी से देखा जा सके। आज हम सूर्य ग्रहण के बारे में बात कर रहे हैं, जो एक महत्वपूर्ण खगोलीय घटना है। इस दिन लोगों को आकाश देखने, तारों को समझने और विज्ञान के प्रति रुच

Introduction The spark counter is a classic yet visually striking detector used in nuclear physics to observe ionizing radiation. It was first explored in the 1940s. This device provides a direct and fascinating way to detect alpha particles through visible sparks produced in air. Unlike conventional detectors that require thin windows, the spark counter operates in a windowless configuration. This makes it especially suitable for detecting alpha particles with very short ran

Now.. we are in April, 2026.. On 7 December, 2021, I had an opportunity to deliver a public talk on the salient features of the National Education Policy (NEP)-2020. At that time, the policy had just been introduced. The universities across the country were in the initial phase of understanding and preparing for its implementation. In universities and many institutions, authorities there had formed committees and special cells to study/prepare its framework and explore possib

भारत की ऊर्जा यात्रा में नाभिकीय ऊर्जा एक महत्वपूर्ण भूमिका निभा रही है। नाभिकीय ऊर्जा संयंत्रों में ऊर्जा परमाणु नाभिक के विखंडन से प्राप्त होती है। जब किसी भारी परमाणु का परमाणु नाभिक टूटता है, तो बहुत बड़ी मात्रा में ऊर्जा उत्पन्न होती है और साथ-साथ कुछ न्यूट्रॉन भी निकलते हैं। ये न्यूट्रॉन आगे अन्य परमाणु नाभिकों का विखंडन करते हैं और इस प्रकार एक सतत श्रृंखलाबद्ध प्रक्रिया चलती रहती है, जिसे श्रृंखला अभिक्रिया कहा जाता है। उदाहरण के रूप में, जब यूरेनियम-२३५ के एक परमाणु

Presently, India, with a population of over 1.4 billion people, is the world’s fifth-largest economy. To meet the needs of society and industry, the country faces a growing energy crisis. The enormous demand for energy production must be balanced with environmental sustainability. The current energy mix includes coal, natural gas, hydro, nuclear power, and increasing contributions from renewable sources such as wind and solar energy. Policymakers must ensure that this energy

Why discussions about nuclear power, deterrence, and security matter today... In recent months, global discussions have increasingly focused on rising geopolitical tensions and military escalations between several nations. Many nations are involved at the moment in these escalations. There are discussions on the issues, with colleagues and friends. There are debates on news channels, there are discussions, as well. The public conversations have once again raised an important

Today, we will explore the life and scientific legacy of Ernest Rutherford, one of the pioneering scientists who laid the foundation of nuclear physics. Ernest Rutherford, often referred to as the " father of nuclear physics " made some of the most groundbreaking contributions in the fields of physics and chemistry. His experiments not only changed our understanding of the atom but also laid the foundation for nuclear science and quantum mechanics. Rutherford’s discoveries, s

If India wants growth, jobs, and security, it must secure its energy future today. The vision of Viksit Bharat 2047 depends on a large and steady supply of energy. Energy is the backbone of development and supports every sector of the nation. India uses many energy sources such as coal, solar, wind, and hydropower. Each source has its own advantages and limitations. Renewable energy is clean but not always available, as energy demand continues day and night regardless of sunl

Nuclear science plays a vital role in modern life and national development. It supports clean and reliable nuclear power, helping meet India’s growing energy demand while reducing carbon emissions. Thus nuclear energy is environment friendly. Nuclear technologies are also widely used in healthcare, especially in medical imaging, radiotherapy, and cancer treatment, improving early diagnosis and saving lives. These applications directly contribute to the sustainable development

A Legacy Shaped by Marie Curie: “Her work is still affecting the world, even today” More than ninety years after her passing, Marie Curie remains a guiding light for science and humanity. Her discoveries reshaped physics and chemistry, laid the foundation of nuclear science, and transformed medicine forever. Few scientists have left a legacy so powerful, and so personal. Born as Maria Salomea Skłodowska on 7 November, 1867 in Warsaw, Poland, Marie Curie rose from modest begin

(UNESCO International Year of Quantum Science and Technology) UNESCO-declared 2025, as the International Year of Quantum Science and Technology to celebrates a century the ideas that transformed our understanding of nature. One of the most beautiful aspects of this celebration is to tell the young generation that the foundations of quantum physics are not confined only to the high-end research facilities. However, they can be explored and experienced through hands-on experim

जब हम radiation शब्द सुनते हैं, तो आमतौर पर nuclear reactors, X-rays या atomic accidents हमारे दिमाग में आते हैं। लेकिन वास्तव में natural radiation हमारे चारों ओर हर समय मौजूद रहती है। यह पृथ्वी के बनने के समय से ही environment का हिस्सा रही है और हवा, मिट्टी, पानी, भोजन तथा हमारे शरीर के भीतर भी पाई जाती है। इसलिए radiation केवल मानव-निर्मित तकनीकों से जुड़ी चीज़ नहीं है, बल्कि यह प्रकृति का भी एक अभिन्न भाग है। Natural radiation मुख्य रूप से तीन स्रोतों से आती है—cosmic, t

2025 का भौतिकी का नोबेल पुरस्कार तीन महान वैज्ञानिकों: जॉन क्लार्क, मिशेल एच. डेवोरेट और जॉन एम. मार्टिनिस, को दिया गया है। यह पुरस्कार उन्हें इसलिए मिला क्योंकि इन वैज्ञानिकों ने क्वांटम यांत्रिकी के नियमों को बड़े और दिखाई देने वाले सिस्टमों में लागू करके दिखाया, जिन्हें हमारी आँखों से भी देखा जा सकता है। इससे पहले क्वांटम सिद्धांत केवल सूक्ष्म कणों जैसे इलेक्ट्रॉन, प्रोटॉन और परमाणु तक सीमित समझे जाते थे। विशेष रूप से,यह पुरस्कार इस वर्ष के लिए और भी महत्वपूर्ण बन जाता है

SHANTI Bill 2025: Energy for Development, Stability, and a Peaceful Future S ustainable H arnessing and A dvancement of N uclear energy for T ransforming I ndia ( SHANTI ). It’s a well-chosen acronym because it also carries the meaning of “peace, stability, and balance,” which aligns nicely. India is moving steadily on the path of development. As our population grows and our economy expands, the demand for electricity continues to rise. Power is needed everywhere, at home, in

Spontaneous fission lets heavy nuclei split on their own. The process releases neutrons and lots of energy. Scientists use it to study nuclei and test various types of detectors. Spontaneous Fission is a natural process in which a very heavy atomic nucleus splits into two smaller nuclei on its own, without being struck by any external particle. It is the only known spontaneous nuclear process that produces heavy, energetic charged particles heavier than alpha particles. The f

क्वांटम दुनिया में कण एक ही समय में दो जगह हो सकते हैं। वे ऐसा इसलिए कर पाते हैं क्योंकि उनका अस्तित्व एक निश्चित बिंदु पर नहीं, बल्कि एक वेवफंक्शन के रूप में फैला होता है, जो बताता है कि कण कहाँ–कहाँ मिलने की संभावना है। इसी कारण वे एक साथ कई तय ऊर्जा स्तरों में रह सकते हैं , इसे सुपरपोज़िशन कहा जाता है। वे ऊर्जा की बड़ी बाधाएँ भी बिना किसी बल के पार कर लेते हैं।क्योंकि उनकी वेवफंक्शन बाधा के भीतर और उसके पार तक फैलती है, और इसी फैलाव की वजह से कण के पास बाधा को पार करने की

China has recently demonstrated a significant advance in nuclear technology by successfully converting thorium to uranium fuel inside its operating molten salt reactor, the 2-MWth TMSR-LF1. This achievement is the first experimental proof of thorium breeding in a liquid-fuel molten salt reactor (MSR) anywhere in the world. It represents the culmination of a decade-long effort involving nearly a hundred Chinese institutions and a fully indigenous supply chain. For India, this
