What are the basics of computer science? Computer science is the study of what computers can do, and the processes that make them function. Computer science is extremely relevant in our daily lives, at school, work, and in our free time. Computers and computer programs are everywhere in our everyday lives. Whether you just want to learn more about something that affects your life, or if you’re thinking of going further into the field, we’ve provided a quick overview of some important computer science principles. Physics uses the scientific method to help uncover the basic principles governing light and matter, and to discover the implications of those laws. It assumes that there are rules by which the universe functions, and that those laws can be at least partially understood by humans. It is also commonly believed that those laws could be used to predict everything about the universe’s future if complete information was available about the present state of all light and matter.
