🎉 Did you know? On a cold day in December 1864, James Clerk Maxwell dropped a science bomb on the Royal Society of London. He read out his paper, "A dynamical theory of the electromagnetic field." Sounds fancy, right? Let's break it down!

• Maxwell presented just four equations (talk about being concise!). But, oh boy, did they pack a punch!
• These equations weren't just some random thoughts. They summed up EVERYTHING about electricity and magnetism. Kinda like the Avengers of Physics!

In the Real World: Think of these equations like the rules of a video game. No matter how you play, these rules determine how everything works. Flip a switch, and a bulb lights up? Thank Maxwell!

• Maxwell’s equations made a young chap named Albert Einstein scratch his head.
• According to Maxwell, electromagnetic waves (like light) should have the same speed no matter how the observer is moving. This was like telling people that no matter how fast you run alongside a train, it will always seem to move at the same speed.

Before Einstein's Insight: Imagine driving a car at 60 mph and throwing a ball forward at 10 mph. You'd think the ball's speed would be 70 mph, right? Well, that's how people thought about light too!

• But Einstein shook the world by saying, "Nah, light's speed is always constant!" This idea was so wild that it turned 200 years of physics on its head.

Fun Fact: Thanks to this thinking, Einstein gave us the theory of Special Relativity!
