Hello!
How are you? Today, let's look at some important scientific discoveries of the last 200 years. There are so many, so we'll look at some key ones!
Look at the picture above. What is it? It's a model of the atom, proposed by Nils Bohr and Ernest Rutherford in 1913. While we already knew what atoms were, this model helped us understand the structure of atoms better than what we had before.
