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 ...
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...
