Niels Bohr

Hello! My name is Niels Bohr. I was born on October 7th, 1885, in a beautiful city called Copenhagen in Denmark. My house was full of books and interesting conversations. My father was a professor, and he taught me to always ask questions. I loved figuring out how things worked, and I knew from a young age that I wanted to be a scientist.

When I grew up, I went to a university to study science, especially physics, which is the study of how everything in the universe moves and works. I was fascinated by the tiniest things you can imagine: atoms! Atoms are the building blocks of everything—you, your chair, and even the stars in the sky. In 1911, I traveled to England to work with other great scientists. We all wanted to understand what an atom actually looked like on the inside.

Other scientists thought atoms had parts, but they weren't sure how they were arranged. In 1913, I had a big idea! I imagined that an atom was like a tiny solar system. It had a center, called a nucleus, just like the sun. And flying around the nucleus were even tinier parts called electrons, like planets in orbit. My new picture, called the Bohr model, helped everyone understand atoms better. For this discovery, I was given a very special award in 1922 called the Nobel Prize in Physics. I was so proud!

Later in my life, there was a very difficult time in the world called World War II. Because my family was in danger, we had to escape from our home in 1943. I always believed that science should be used to help people and bring peace to the world. I lived to be 77 years old, and I spent my life sharing ideas and learning new things. Today, scientists still use my ideas to understand the world, and there is even a tiny element on the periodic table named Bohrium, in my honor.
