Basic Concepts of String Theory

### Article: Basic Concepts of String Theory String theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects known as strings. These strings can vibrate at different frequencies, and the various modes of vibration are thought to correspond to the elementary particles of the Standard Model. String … Read more

Relationship Between Energy and Light Frequency

Studies on Particle Physics

# The Fascinating World of Particle Physics: Studies and Discoveries Particle physics is an enthralling branch of science that delves into the fundamental building blocks of matter and the forces governing their interactions. By studying particles such as quarks, leptons, bosons, and hadrons, scientists strive to unravel the mysteries of the universe at its smallest … Read more

Theory of Mechanical Waves

# Theory of Mechanical Waves Mechanical waves are disturbances that travel through a medium, transferring energy from one location to another. Unlike electromagnetic waves, mechanical waves require a material medium (like air, water, or a solid structure) to propagate. As the wave moves, particles in the medium oscillate around their equilibrium positions, but they do … Read more

Material on Static and Dynamic Fluids

# Understanding Static and Dynamic Fluids: Concepts, Equations, and Example Problems Fluid mechanics is the branch of physics concerned with the behavior of fluids at rest (statics) and in motion (dynamics). It addresses numerous phenomena and practical applications, from the circulation of the blood in the body to the design of complex fluid machinery. ## … Read more

Working Principle of Carnot Engine

# The Working Principle of a Carnot Engine ## Introduction The Carnot engine is the most efficient theoretical heat engine as defined by the laws of thermodynamics. Devised in 1824 by French physicist Sadi Carnot, it serves as a fundamental benchmark for all heat engines. Although a Carnot engine cannot be practically constructed, its principles … Read more

How to Calculate Work and Energy

# How to Calculate Work and Energy Understanding the concepts of work and energy is essential in the field of physics. These concepts are not only theoretical but also have practical applications in everyday life.
