Types of Science



Our goal is to help readers be healthy, wealth and wise and we regularly partner with companies that share that same vision.  Some of the links in this post may be from our partners who may pay us a small commission.

Science is the organized art of trying to understand something that we find, observe, or experience in life. Its applications are very broad so, as you may have guessed, the types of science cover every category imaginable.

Subsets of science focus their studies on everything from ancient fossils (known as paleontologists) and ancient structures (known as archaeologists) to the more obscure, such as the study of sound (known as acoustical science).

It’d be impossible to cover every single scientific discipline at such a pinpointed level, but if you’re looking to better understand how scientists understand things, here’s an overview of the three branches of science and some of the popular subsets within each.

1. Life Sciences

Life sciences are all about better understanding living organisms, and subsets include some of the most well-known areas of scientific study.
