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.

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…
