1913 in science

Well kiddo, 1913 was a very important year for science. It was a time when lots of smart people were finding out new things about the world around us. Here are a few things that happened that year:

1. The Bohr Model: A scientist named Niels Bohr came up with a new way to think about atoms. He said that atoms were like tiny solar systems, with a nucleus at the center (like the sun) and electrons orbiting around it (like planets). This was a big deal because it helped people understand how atoms work, which is really important in chemistry and other sciences.

2. The Theory of General Relativity: Another scientist named Albert Einstein came up with a new theory about gravity. He said that gravity isn't a force that pulls things together, but rather a distortion in the fabric of space and time. This sounds pretty wild, but it actually explains a lot of things that we observe in space (like why planets orbit the sun).

3. The Discovery of Isotopes: Scientists discovered that some elements (like carbon and oxygen) actually come in different forms, called isotopes. This means that they have the same number of protons (which determines what element they are), but different numbers of neutrons. This was a big deal because it helped scientists understand more about how elements work and how they interact with each other.

Overall, 1913 was a really exciting time for science, with lots of breakthroughs and discoveries that still have a big impact on our understanding of the world today.
