As we know it today, "science" frequently is refering to a means of pursuing knowledge, not merely the knowledge itself. It is also often limited to those branches of investigation that try to describe the phenomena of the product universe. In the 17th and 18th centuries scientists increasingly attempted to formulate know-how with regard to laws of nature for example Newton's laws of movement. And during the period of the 19th century, the term "science" became even more associated with the scientific procedure itself, as a disciplined solution to study the natural earth, which include physics, chemistry, geology and biology. It really is in the 19th century as well that the word scientist was made by the naturalist-theologian William Whewell to differentiate between those who sought know-how on nature from those that sought other styles of knowledge.

However, "science" in addition has continued to be found in an easy sense denoting reputable, teachable knowledge about a subject, as in modern terminology like library science or laptop or computer science. This is as well reflected in the names of some regions of academic study such as for example "social science" or "political science".
