Maxwell's Equations changed how we understand classical physics. They brought together electricity and magnetism into one big idea called electromagnetism. These four equations help us see how electric and magnetic fields work together and move through space.

1. Bringing It All Together: Before Maxwell, people thought of electricity and magnetism as two separate things. His equations showed that they are connected. For example, when an electric field changes, it creates a magnetic field. This is explained by something called Faraday's Law.

2. Traveling Waves: Maxwell's Equations tell us that electromagnetic waves move through empty space at the speed of light. This meant that light is actually an electromagnetic wave! This idea changed how we think about light.

3. Technology Foundations: These equations are the basis for many technologies, like radios, microwaves, and even how we communicate today. They have had a huge impact on both science and everyday life.

In short, Maxwell's Equations not only changed classical physics but also opened the door for many modern discoveries in science and technology.
