Introduction The immense importance of Einstein Field Equations ("EFE") warrants a thorough understanding of every single element contained within them. Einstein's equation is another name for the Einstein Field Equation. Ten equations make up this set which is derived from the General Theory of Relativity of Albert Einstein. This tutorial aims to present a tight, clear, and simple logic of EFE that is also comprehensive so that any general mathematician can understand EFE by simply reading this tutorial. In this tutorial, we will describe Einstein Field Equations, metric tensor, Einstein tensor, properties of Einstein tensor, the cosmological constant, and Practical ... Read More

Introduction Whenever we do some work experiment with water or any liquid, we observe that some objects are immersed in water whereas some float over it. For example, ice cubes float on water. Because ice cubes are less dense than water. But if we put a stone in water it will sink. Because stone is denser than water. This is happen because every substance has a different density. Specific gravity is very closely related to Density. And it is also known as relative Density. At the industry level, various techniques, like hydrometer, hydrostatic balance, pycnometer, etc., are used to calculate ... Read More

Introduction Centroid is the term that applies to a geometrically balanced figure or an object. It is the center of that figure or object. The methods to find the center of a symmetrical entity differs, but it exists, and there is no confusion about that. For example, a triangle has the centroid which is the meeting point of three medians. In contrast to the centroid, the center of gravity is a broader term that encompasses symmetrical and asymmetrical objects and figures. It is interesting to note that the center of gravity and the centroid are the same for a symmetrical ... Read More
