Definition and Explanation of (BCE) BCE stand for "Before Common Era, " and may be a framework of dating chronicled occasions that happened earlier than the year 1 CE. It is utilized as an elective to the conventional "BC" (Before Christ) dating framework, which is based on the birth of ... Read More

Introduction Bohr’s atomic model was a major breakthrough in the field of study of atomic structure. Atoms are a basic unit of all materials. According to the Bohr atomic model atoms contain a small central core called a nucleus which is full of positive charges. Electrons round about the nucleus ... Read More

Introduction Azimuthal quantum number and their study are important to understand the quantum nature of matter. Atoms are a basic unit of a material. According to the Bohr atom model atoms contain a small central core called a nucleus which is full of positive charges. Electrons are round about the ... Read More

Introduction Brail system is developed for visually impaired people. Generally writing systems are the visual representation that is used to share our feelings and communicate with each other. Many types of communication were followed from the early times. Braille is one such system of communication. In such systems, the conveyer ... Read More

Introduction Average Speed and Average Velocity are two important concepts of kinematics. The ratio between distance cover by an object and time taken to cover is called Speed. Velocity is the ratio of displacement of an object and time taken. Speed is a scalar quantity. Velocity is a ... Read More

Introduction Boltzmann’s constant is denoted by letter $\mathrm{k_B}$. Certain physical quantities in physics remain constant with time and are universal constants. These are called fundamental physical constants. For example - speed of light (c), Planck's constant $\mathrm{(\hslash)}$, Boltzmann constant $\mathrm{(k_B)}$ are such quantities. Boltzmann constant first time arises in physics ... Read More

Introduction Boltzmann Equation describes the reactions of fluids with temperatures. When a fluid is in motion, the change in the physical amount of thermal energy and momentum is calculated by Boltzmann's equation. This equation is also known as Boltzmann Transport Equation (BTE). Thermal conductivity, viscosity, and electrical conductivity ... Read More

Introduction Band theory of Solids is essential to understand how energy is distributed in a solid. A huge number of atoms attached closely together is called Solids. Isolated atoms are initiated closer and closer simultaneously to construct solid. Valence electrons in a crystal are grouped into a single structure for ... Read More

Introduction Archimedes’ Principle is an important principle of fluid mechanics. It is discovered by a Greek mathematician and scientist Archimedes. This principle is utilized to estimate the volume of an object that has an irregular shape, density, and distinct gravity of an object. What is Archimedes' Principle? A body placed ... Read More

Introduction Atmospheric pressure effects everything on the earth. We are using the basic concept of pressure in every action in our daily activities. For example, the pressure on the knife edge is high. But we don't know what science is behind on that knife edge. There is a high pressure ... Read More
