Prime Minister Narendra Modi’s Independence Day address from the Red Fort on 15th August 2026 presented a significant development framework under the idea of ‘Shakti ki Saptadhara’, the seven streams of national strength. These streams are Manufacturing, Agriculture and Food Production, Technology and Innovation, Gati Shakti and Infrastructure, Raksha (Defence) Shakti, Green and Blue Economy, and Soft Power. Rather than viewing them as seven independent sectors, the speech presents them as mutually reinforcing capabilities that can raise India’s productive capacity, technological competence, economic resilience and global influence. The Prime Minister called for these streams to generate new momentum over the…
In recent years, the term ‘Net Zero’ has become central to discussions about climate change, energy security, and sustainable development. Governments, industries, scientists, and environmental organisations across the world are working toward reducing greenhouse gas emissions and building a cleaner future, but achieving Net Zero is not an easy task. It requires revolutionary technologies capable of transforming the way we produce energy, manufacture goods, manage waste, and protect the environment. The Earth’s average temperature is rising due to increasing greenhouse gases such as carbon dioxide (CO₂), methane, and nitrous oxide. Fossil fuel combustion, industrial processes, transportation, agriculture, and waste disposal…
In January 1935, Sir Chandrasekhara Venkata Raman wrote a remarkable letter to the German physicist Max Born, inviting him to join the Indian Institute of Science (IISc), Bangalore, as a visiting faculty member in Theoretical Physics. At first glance, the letter may appear to be a routine academic invitation. In reality, it was a bold and visionary intervention, one that revealed Raman’s deep grasp of the unfolding quantum revolution and his determination to anchor India firmly within its intellectual core. This single act, among many others, helped lay the conceptual and institutional foundations for what we today recognise as India’s…

Rapid economic growth, expanding digital infrastructure, urbanisation, and rising aspirations have led to an unprecedented surge in electricity demand. At the same time, climate change, environmental degradation, and geopolitical uncertainties linked to fossil fuels have made the existing energy paradigm increasingly unsustainable. It is within this complex scientific, environmental, and policy landscape that the SHANTI Act 2025 (Sustainable Harnessing and Advancement of Nuclear Technology for India) assumes critical importance, it was introduced in the Lok Sabha on 15 December 2025 and passed…
In an increasingly interconnected and complex world, the boundaries of diplomacy have expanded beyond traditional politics and trade agreements. One of the most significant developments in the modern era is the rise of science diplomacy, the use of scientific cooperation and knowledge sharing as a tool for fostering international relations, solving global challenges, and enhancing a nation’s influence. India, with its rich scientific heritage and rapidly growing research capabilities, has embraced science diplomacy as a means to further its geopolitical ambitions, strengthen international partnerships, and address global challenges. Science diplomacy has become an essential instrument for India in its efforts…

Shampoo has deep roots in India, tracing back thousands of years and reflecting the country’s strong connection to natural remedies and hygiene practices. In the Indian subcontinent, various herbs and their extracts have long served as hair cleansers. The earliest forms of shampoo can be traced back to the Indus Valley Civilisation. An effective ancient shampoo was created by boiling soapberries (Sapindus) with dried Indian gooseberry (Amla) and other herbs, then straining the mixture.…
Sanskrit, an ancient language with a rich heritage, possesses substantial potential as a modern scientific language due to its inherent precision, structure, and historical contributions to various scientific disciplines. The renewed interest in Sanskrit stems from its unique characteristics, which align well with the demands of contemporary scientific discourse. Its phonetic precision, grammatical rigour, and extensive vocabulary make it an excellent medium for clear and unambiguous communication. A key factor in Sanskrit’s suitability for science is its highly structured and systematic grammar, exemplified in Panini’s Ashtadhyayi. This foundational work provides an algorithmic approach to language, making it particularly effective for…

The first volume of the article laid the groundwork by exploring the nuanced characteristics of musical sound and providing a comprehensive classification of Indian musical instruments. It then delved into Tantu Vadya, or stringed instruments, elucidating their operation through a scientific lens, unraveling the physics behind their melodic expression. Building upon this foundation, the second volume expanded the discourse to include Sushir Vadya, or wind instruments, and Avanaddha Vadya, encompassing percussion instruments or drums. Readers were treated…
Editor’s Note: This is the second of the three-part series presented by Science India to explore the scientific basis of the rich heritage of Indian music The first volume of this article embarked on a comprehensive journey through the intricate world of music, beginning with a meticulous examination of the characteristics inherent in musical sound. These characteristics serve as the foundational pillars upon which the subsequent exploration unfolds. Following this insightful discussion, the article meticulously delved into the classification of Indian musical instruments, providing a structured framework to navigate the rich tapestry of traditional music. Transitioning seamlessly from this classification,…
Editor’s Note: Given the immense richness of musical traditions of the subcontinent, Science India presents a three-part series that takes an in-depth look at what gives Indian music its unparalleled strength The appreciation of art, particularly music and visual arts, relies heavily on the human senses of hearing and sight. These senses afford us the highest aesthetic pleasures derived from experiencing the beauty of sound and imagery. Our comprehension of the world is greatly enriched through these sensory organs, upon which our very existence depends. Sound and light are foundational elements in our daily lives. While light can traverse through vacuum, sound…
