Einstein redefined gravity not as a force between masses, but as the curvature of spacetime . Massive objects like stars and planets warp the "fabric" of the universe, and this curvature dictates how objects move. 3. The Standard Model: The Building Blocks

At the atomic level, nature behaves in ways that defy everyday intuition.

Modern physics seeks to categorize all known subatomic particles and the forces that govern them. Introduction to the Basic Concepts of Modern Ph...

Matter is composed of quarks (which make up protons and neutrons) and leptons (such as electrons).

This theory introduces the idea that the laws of physics are the same for all observers moving at a constant speed, and that the speed of light is a universal constant. It famously led to the equation , showing that mass and energy are interchangeable. Einstein redefined gravity not as a force between

Introduction to Modern Physics Modern physics is the study of the underlying principles that govern the universe at its most extreme scales—from the subatomic to the cosmological. Emerging at the dawn of the 20th century, it moved beyond the certainties of "Classical Physics" (Newtonian mechanics and Maxwell’s electromagnetism) to address phenomena that the old laws could not explain. 1. Quantum Mechanics: The Physics of the Very Small

Objects like electrons and photons exhibit properties of both particles and waves. They are neither one nor the other exclusively, but a "quantum" entity that behaves differently depending on how it is measured. The Standard Model: The Building Blocks At the

Unlike the deterministic nature of classical physics, modern physics is built on . The state of a particle is described by a mathematical "wave-function." Until an observation is made, a particle exists in a superposition of multiple states at once.
