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 escakations. 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

युवा विद्यार्थियों में वैज्ञानिक दृष्टिकोण और वैज्ञानिक स्वभाव विकसित करने के उद्देश्य से एक महत्वपूर्ण पहल की गई। राष्ट्रीय विज्ञान दिवस समारोह के अंतर्गत 21 से 28 फरवरी, 2022 तक एक सप्ताह का विज्ञान जागरूकता सप्ताह आयोजित किया गया। इस दौरान विद्यार्थियों को विज्ञान प्रज्ञान सप्ताह में भाग लेने के लिए आमंत्रित किया गया, ताकि वे विज्ञान को समझें, उसे अपने जीवन से जोड़ें और वैज्ञानिक स्वभाव को आत्मसात कर सकें। यह कार्यक्रम विज्ञान एवं प्रौद्योगिकी विभाग, भारत सरकार द्वारा वित्

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

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

Step into the AMU's Physics Department’s Heritage Science Museum, and you are transported back to the early 19th century. A time when electricity was mysterious, and scientists were explorers trying to have information about invisible forces. Picture a laboratory lit by flickering oil lamps, with curious minds experimenting with wires, coils, and magnets, trying to understand currents that flowed unseen. Luigi Galvani, born in Bologna, Italy, in 1737, was a distinguished phys

India is standing at a turning point in a race to Viksit Bharat @2047. A new nuclear renaissance seems to be starting to take shape. But quietly, and powerfully heading forward. The recent Union Budget has set aside ₹20,000 crore for expanding our nuclear power capacity. This is not just adding another number in the budget. It is a message for the country. A message that India is willing and ready to dream big again. In continuation to the above, as per some reports in media,

I recently dug into the recent IAEA’s Nuclear Power Status 2025  [IAEA Power Reactor Information System (PRIS), Nuclear Power Status 2025  (21 November 2025)], on Power Reactor Information System ( PRIS). It was like reading the field’s next chapter in real time. The report doesn’t just list numbers, it signals a turning point, that policymakers, and engineers are treating nuclear as a central, real and deployable tool in the race to NET ZERO . For us, the nuclear physicists

by: Prof. B. P. Singh, Department of Physics, Aligarh Muslim University, Aligarh, INDIA Ernest Rutherford (1871–1937), born in New Zealand, is known as the father of nuclear physics . Through his famous alpha scattering (Gold Foil) experiment, he demonstrated that atoms have a tiny, dense, positively charged nucleus. This overturned the earlier plum pudding model proposed by J. J. Thomson. He also achieved the first artificial nuclear reaction by converting nitrogen into oxy

भारत लंबे समय से न्यूक्लियर भौतिकी के क्षेत्र में अग्रणी रहा है और ऊर्जा, चिकित्सा, उद्योग और पर्यावरण निगरानी में महत्वपूर्ण योगदान दिया है। इसके बावजूद, इस क्षेत्र को कई चुनौतियों का सामना करना पड़ रहा है, जैसे कि छात्रों की रुचि में कमी, जनता में सीमित पहचान, नीतिगत समर्थन का अभाव और विश्वविद्यालयों में अपर्याप्त न्यूक्लियर भौतिकी प्रयोगशाला सुविधाएँ। एक्सेलेरेटर और प्रयोगात्मक अवसंरचना तक पहुंच सीमित है, जिससे अनुसंधान की गति धीमी होती है और छात्रों को व्यावहारिक प्रशिक्ष

From Atomic Bonds to Nuclear Fusion Everything in the universe is made of atoms and at the heart of every atom lies its nucleus, held together by incredibly strong nuclear forces. When two nuclei come close enough to each other, they can merge and form a heavier nucleus, a process called nuclear fusion. Fusion is nature’s way of producing energy. It powers the Sun and stars, where extreme temperature and pressure allow light nuclei like hydrogen to fuse into helium, releasing
