Random Thoughts 3 continues Dr. Partha Majumdar's acclaimed series of reflections that bridge ancient wisdom and modern disruption. This third volume is both a meditation on Dharma and a practical exploration of how Data and Decisions shape our world in an age of Artificial Intelligence, disrupted education, and accelerating change. The book opens with "Vignaharta in the Valley", where Lord Ganesha's timeless symbolism is reframed as a blueprint for Artificial Intelligence. Each element of Ganesha's form-his large ears, pot belly, single tusk, and even his mouse vehicle-is interpreted as an ethical and operational metaphor for data, algorithms, and responsible technology. Here, AI emerges as the modern Vignaharta: a remover of obstacles in healthcare, logistics, and finance, but also a placer of new challenges such as bias, opacity, and disruption. Ganesha's form provides guidance for ensuring that intelligence remains transparent, fair, and human-centred. In "The Project of Life", Dr. Majumdar presents a personal and national philosophy: living not through unconscious operations, but through conscious projects. Drawing on Independence Day reflections, daily practices, and historical examples from Leonardo da Vinci to Marie Curie, he articulates the Project Mindset. This perspective transforms routine tasks into meaningful engagements, cultivating flow, novelty, and continuous improvement. It is a call for individuals and nations alike to treat life as a series of purposeful projects, turning the mundane into a source of meaning and vitality. "From Blueprint to Intelligence" explores the mechanics and ethics of modern AI, Industry 5.0, and data-driven governance. Here, the author connects philosophy with prescriptive analytics, examining how explainability, fairness, and accountability are not just technical goals but moral imperatives. The broken tusk of Ganesha becomes a metaphor for the sacrifices required in developing AI-whether environmental, human, or ethical-and a reminder that progress without responsibility is incomplete. In "The Compulsion of 1991", he turns to economics and history, reflecting on the liberalisation of India's economy and its ripple effects on society, technology, and thought. This chapter places national transformation within the same frame as personal and technological change: a continuous negotiation between opportunity and responsibility. The volume culminates in "Town Planning and the Power of Linear Programming", where the author demonstrates how mathematical optimisation can balance competing demands of cost, equity, and sustainability in urban development. Through a detailed case of housing allocation, he illustrates how surplus and bottlenecks in data mirror societal challenges, and how Dharma ensures that optimisation is guided by fairness, inclusivity, and long-term vision. Across these chapters, Random Thoughts 3 remains true to the spirit of the series: not an academic manual or a prescriptive doctrine, but a collection of lived insights. The essays blend professional expertise, personal experience, and philosophical depth. They open doors rather than close debates, encouraging readers to think freely and responsibly. At its heart, this book embodies the framework of 3D: Data, Dharma, and Decisions. Data provides clarity, Dharma ensures ethical grounding, and Decisions transform knowledge into action. In a disrupted world-where speed often overwhelms depth-Dr. Majumdar reminds us that slowing down to reflect is itself revolutionary. Whether you are a technologist, policymaker, student, or seeker, Random Thoughts 3 offers a unique lens to engage with today's challenges. It is a meditation on wisdom in the algorithmic age, a philosophy of life in project form, and a call to align progress with purpose.
