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

Albert Einstein’s theories revolutionized our understanding of space, time, and mass.

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

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.

Proposed by Werner Heisenberg, this principle states that it is impossible to know both the exact position and the exact momentum of a particle simultaneously. The more precisely we measure one, the less precisely we know the other. 2. Relativity: The Physics of High Speeds and Gravity

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 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
