Matter is composed of quarks (which make up protons and neutrons) and leptons (such as electrons).
These particles interact through four fundamental forces: Gravity , Electromagnetism , the Strong Nuclear Force (which holds nuclei together), and the Weak Nuclear Force (responsible for radioactive decay). 4. Wave-Function and Probability Introduction to the Basic Concepts of Modern Ph...
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 Matter is composed of quarks (which make up
Modern physics seeks to categorize all known subatomic particles and the forces that govern them. Quantum Mechanics: The Physics of the Very Small
At the atomic level, nature behaves in ways that defy everyday intuition.
