We hope you have enjoyed this introductory journey through the world of Computer Science. People tend to think of Science, Technology, Engineering, and Mathematics (STEM) as three separate things, they are actually closely connected.

For example, scientists use the technologies that engineers create (such as microscopes, monitors, and meters) to conduct their research. When engineers start to design a new technology, they call on the knowledge of the natural world developed by scientists (for example, the law of gravity or how fluid flows). Engineering, science, and technology connect to—and influence—each other.

STEM fields also influence (and are influenced by) society. Our human values, needs, or problems often determine what questions scientists investigate and what problems engineers tackle. Meanwhile the technologies that are the products of science and engineering influence society and change human culture (just think of the impacts of cars and mobile phones!).

The Figure below shows how STEM connects to society:

Here is another way to look at it:
