Book review The Changing World Order by Ray Dalio

Book Review: The Changing World Order by Ray Dalio Ray Dalio, the founder of Bridgewater Associates, presents a compelling analysis of global economic and political cycles in The Changing World Order: Why Nations Succeed and Fail. Drawing from history, economics, and geopolitics, Dalio explores how major powers rise and fall, offering a framework for understanding today’s shifting global landscape. Summary The book is structured around Dalio’s research into historical cycles of prosperity and decline, using data spanning over 500 years. He argues that nations follow predictable patterns, rising through innovation, economic strength, and stability before succumbing to debt crises, internal conflicts, and external pressures. By comparing past empires—such as the Dutch, British, and American—with the current rise of China, Dalio provides insights into where the world is heading. A key theme of the book is the interplay between debt cycles, wealth gaps, and shifts in global power. Dalio explains how economic bubbles and debt accumulation often precede declines, while social and political divisions exacerbate instability. He highlights China’s rapid ascent as a global superpower, suggesting that the U.S.-China rivalry will define the coming decades. Analysis Dalio’s strength lies in his ability to distill complex financial and geopolitical concepts into accessible narratives. His use of historical parallels makes the book engaging, while data-driven analysis adds credibility to his arguments. The book is particularly valuable for investors, policymakers, and anyone interested in understanding global trends. However, some critics argue that Dalio’s deterministic approach oversimplifies the nuances of history. While cycles exist, unique factors—such as technological disruptions and cultural shifts—can alter trajectories. Additionally, his predictions, while well-reasoned, are not guarantees. Final Verdict The Changing World Order is an insightful and thought-provoking book that provides a valuable perspective on global economic and political trends. While not without its limitations, it offers a compelling framework for understanding the forces shaping our world. Highly recommended for those interested in history, economics, and global affairs. Rating: 4.5/5

Energy management teqniq- episode 1

Like water is the lifeline of human civilisation. Energy also is another lifeline which can make and break our entire ecosystem of this planet. It has a profound influence on our healthy lifestyle and inclusive growth. Industries and commercial establishments are bulk consumers followed by retail domestic consumers. If we look our energy consumption pattern in India, it is seen that  we consume energy for Industry set up 44% whereas the global industry consumption is 50%. The second highest consumer of energy is transport sector that consumes 17% nationally and 20% globally. This transport sector consumes 40% petroleum energy. The third highest consumer is the residential and commercial setup which consumes 14% nationally and 30% globally and there are other energy users that consumes 10%.  Most common form of primary energy sources are Oil, Coal & Gas and the global data point for those sources are Oil: 33%, Coal: 30% & gas: 24%.Energy reserves are measured in number of years to exhaust based on current consumption rate. Therefore our depleting Energy reserves identified for three primary energies. Coal we have : 113 years reserve (globally) & 100 years nationally. Whenever we are referring nationally it refers to India. Oil we have: 53 years reserve globally and 17.5 years nationally. Gas we have: 55 years reserve globally & 40 years (Nationally)  Considering all these we must understand the need for energy conservation strategy to reduce our energy dependence. Otherwise we will hit a point of no return. Please remember we have just one planet “the earth.”Therefore energy audit is a must have KPI for every energy consumers irrespective of size whether big or small. What is an energy audit. The moment we use the word audit it subtly popped the image of finance auditing methods where mistakes finding approach in the books of account are prime objective. Unlike finance auditing energy audit is a suggestive interaction and deliberation between users and team of energy experts to optimise the use of energy to bring down the rate of energy depletion on this earth.  Therefore, Energy audit is an investigation of all types facilities which consumes energy. Both historical & current consumption are thoroughly studied and strategies are formulated to optimise the consumption without affecting the business need. Energy such as electrical, oil, coal, natural gas are consumed in business establishment depending on their respective business need. Energy are classified into various category which we will understand in this series of episode. It is classified as primary or secondary, commercial or non-commercial/ and renewable or non-renewable. Energy audit is the foundation of successful energy management programme and act as an benchmark for managing energy efficiently for the entire facility bringing in commercial advantage as the days progress this will be a costlier line items which business house won’t be able afford without selling out more from their pocket. It reduces a good amount of money making the establishment uncompetitive in the market.  In this series we will discuss: An introduction to energy – in this segment, we will discuss the scenario of global & national energy situation it’s present and future Scope of audit: Types of audit: Method of audit: Step by step guide to provide: Criteria of audit: Substitution and solution: Implementation method Measurement of saving

Joshi Math sinking Why

Why Joshi math is sinking? The recent trouble in Joshi math, is it a man-made disaster or a natural calamity? Though blaming each other is going on, let us still find out why these settlement cracks are becoming prominent. By the way, this podcast shall be treated as an academic work not to be correlated with any political mandate. How this Himalayan mountain was formed, let us visit history a bit. 50 -60 million years ago 2 large plates came closer to the Tethys ocean. Indian continental plate moved towards the Eurasian continental plate. Because of this movement, the bed-level soil sediment crust between the plates formed the mountain Himalayas. This oceanic bed soil is very loose by its source as oceanic sediment. This Indian continental plate is still moving towards the Eurasian plate, and therefore, the Himalayan mountain is gradually becoming higher. During this movement, seismic tremors cause multiple earthquakes, which we all know. So primarily, it is a natural phenomenon that we can not escape. So what went wrong, and how went wrong? This underlying soil profile of Joshi math is extremely loose, and therefore its bearing capacity is very low, and the engineering behavior of this soil changes with %age of the water inside it. Since River alakananda flows heavily through Joshi math, it has many narrow & micro water channels seeping through the soil, and the change of the water level in the river, it affects the bearing capacity of the soil. You may experiment in your house with a handful amount of Wheat flowers over a newspaper sheet and shape it like a conical shaped mountain and then add a few drops of water and see the mountain made of wheat-flower will slowly lose its height. The same way the soil of Joshi math is behaving. Now the question is why it happens after so many years of existence. It is happening now because of some over-exploiting man-made activities; before going into that, let me explain two forces in Geologic evolution. Endogenic      force Exogenic      force Endogenic force is created by nature to develop and adjust the earth's plate to create more hills, lakes, mountains, deserts, etc. It is a natural adjustment by the mother earth Exogenic force is the external force that comes from rain, snow, flood, man-made activity like construction, etc. Exogenic forces are more dangerous than endogenic forces. So, in a nutshell, we can conclude that nature should not be overexploited, and we have to find a balance between development and protecting nature. So sustainable development is a must in today’s context otherwise, nature’s fury might end up killing our development in no time.
