Review of General Relativity in a Nutshell 1

Jorge Pinochet published General Relativity in a nutshell in two chapters. Here we are going to review the first one. This chapter was published in 2023, still it is highly recommended for beginners who are just starting to explore the writing and reading journey of physics research papers. In this paper Jorge discussed it in the following order. Abstract Introduction Reimann Geometry and the concept of metric Curvature and geodesics: An intuitive Look The matric of a non-Euclidean manifold: A simple example Riemannian Geometry and the Minkowski Metric of flat space-time We will discuss every single one of these headings. Let’s start with the Abstract; In abstract, Jorge claims that; “Einstein’s general relativity is the best available theory of gravity” . There was a time when Newton’s & Kepler’s gravitational theory was popular for centuries, but now Einstein’s general relativity is being considered as the best available theory of gravity. Einstein's General relativity has ...

Common ground of a science and non-science person

  In the context of the prefaces, we discussed in two previousbooks of our, the terms "science person" and "non-science person" refer to individuals with different levels of familiarity, interest, and expertise in scientific subjects, particularly in fields like chemistry and physics. 1.     Science Person: This term typically refers to individuals who have a background or education in science, technology, engineering, or mathematics (STEM). Science people are generally comfortable with scientific principles, theories, and mathematical concepts. They approach information with a critical and analytical mindset, relying on evidence, logic, and reason to evaluate scientific ideas and concepts. 2.     Non-Science Person: Non-science persons, on the other hand, often lack formal training in STEM fields. They may approach information using intuition, personal experience, or popular opinion rather than scientific reasoning. They might not be as familia...

Difference between science and non-science person

The world around us is governed by the laws of physics, and understanding these laws is essential for making sense of the world we live in. Whether you're interested in the mysteries of the universe or the everyday phenomena we encounter in our daily lives, a fundamental understanding of physics is necessary. If you have already gone through my previous book “ Beyond Reaction ”, you know that the core reason I am writing this book series is to decrease the difference between a science and non-science person. The differences between a science person and a non-science person can be quite significant. Here are some potential differences: Approach to information: A science person is likely to approach information with a critical and analytical mindset. They are likely to evaluate information and arguments based on evidence, logic, and reason. In contrast, a non-science person may rely more heavily on intuition, personal experience, or popular opinion. Familiarity with scientific c...

Science and non-science sphere of knowledge

  There are two spheres of human knowledge, science and non-science. The scientific knowledge deals with the ideas about the world based on inductive reasoning. The scientific research and studies are always open to test, change, improvement, and development. The other sphere of knowledge also known as non-science deals with religions, ethical beliefs, moral precepts, and philosophical ideas. As, the scientific research and studies are generally filled with complicated and long methods of mathematical reasonings, calculations, and equations. A non-science person doesn’t even bear to have a look over it. They also hesitate to even discuss about the scientific theories and studies. In a conversation with a research scholar of Islamic Studies at Jamia Millia Islamia, I was shocked to know about how much they fear from those mathematical calculations and equations. He also told me that, they often require scientific point of view about anything to support their research paper. But ...

Thoughts of Nehru and Tagore

Tryst with Destiny Theme In this speech, delivered at midnight, on August 14, 1947, Nehru speaks about India’s past and remembers the trials and tribulations the people faced to achieve independence. He especially mentions Mahatma Gandhi as the architect of Indian freedom. He emphasizes equality for all sections of society. The speech reveals Nehru’s internationalism, asserting that Indian dreams and those of the world are similar. For Nehru, no nation can exist in isolation. Highlights of speech “ At the stroke of midnight hour, ” Said Nehru, “ when world sleeps , India will awake to life and freedom.” In the first paragraph of speech Nehru is talking about the tryst made with destiny. Now it is time to redeem them very substantially. He said there is time for every suppressed soul to utter and after a long time, it’s ours. “ Are we brave enough and wise enough to grasp this opportunity and accept the challenge of the future? ” In this quotation Nehru is asking to the brave an...
