Interior of Black Hole
The question of what lies inside a black hole sits at the intersection of gravitation, quantum theory, and the philosophy of physical law. In classical general relativity, a black hole is not a material object…

Enthalpy
Enthalpy is a fundamental concept in thermodynamics, one of the most important branches of physics that deals with the relationships between heat, work, and energy in physical systems. It is a state function that helps…
-
Entropy
Entropy stands as a cornerstone of physics, encapsulating the measure of randomness or disorder within any physical system and governing the natural direction of physical processes. At its essence, entropy reflects how energy disperses or…

Evanescent Wave
An evanescent wave is a fascinating and subtle phenomenon in physics that arises when a wave encounters a boundary or an interface in such a way that it cannot propagate through the second medium in…

First Law of Thermodynamics
The First Law of Thermodynamics represents one of the most profound and universal statements in all of physics, asserting that energy is an indestructible quantity—it can shift forms or move between systems, but it can…
-
Force
Force stands as one of the deepest and most essential ideas in the entire domain of physics, forming the backbone of our understanding of movement, interaction, and the nature of matter itself. The notion of…

Frame of Reference
A frame of reference is one of the most fundamental concepts in physics, serving as the basis for describing and understanding motion, rest, and the laws governing the physical universe. It is the conceptual or…
