Brewster’s Angle
Brewster’s angle is a fundamental concept in optics, describing the specific angle at which light, when incident on the interface between two media, becomes perfectly polarized upon reflection. This phenomenon, first described by the Scottish…

Black Body Radiation
Black body radiation is a cornerstone of modern physics, connecting the fields of thermodynamics, statistical mechanics, and quantum theory in a unique way. It refers to the electromagnetic radiation emitted by an idealized object that…
-
Boltzmann Constant
The Boltzmann constant is one of the most fundamental constants in physics, linking the microscopic world of atoms and molecules to the macroscopic quantities we can measure, such as temperature, pressure, and energy. At its…
-
Brewster’s Law
Brewster’s Law, first articulated by Scottish physicist Sir David Brewster in 1815, stands as a cornerstone of optical science, describing the exact circumstance under which light reflected from a transparent surface becomes entirely plane-polarized. When…
-
Boyle’s Law
Boyle’s Law is one of the fundamental principles in classical physics and thermodynamics, describing the relationship between the pressure and volume of a gas when its temperature and the amount of gas remain constant. It…
-
Black Hole
Black holes are among the most mysterious and awe-inspiring objects in the universe, regions of spacetime where gravity is so strong that nothing—not even light—can escape. Born from the collapse of massive stars and predicted…
-
Interior of Black Hole
Black holes sit at the edges of both our universe and our scientific understanding. They are among the strangest objects ever predicted by physics—regions where gravity pulls so strongly that nothing, not even light, can…
-
Bernoulli’s Principle
Among the key ideas that connect classical mechanics with fluid dynamics, one of the most elegant and far-reaching is Bernoulli’s Principle. As we explore it further, we see how it beautifully explains the behavior of…

Detection of Black Hole
Black holes, once regarded as rare curiosities of physics, are now understood to be widespread features of the universe, with their frequency depending on their type and size. Stellar-mass black holes, the remnants of massive…
