Science on Goodpoint is when factual information is obtained by combining observation, trust, insight and logic.

The aim of science is, on the one hand, a comprehension, as complete as possible, of the connection between the sense experiences in their totality, and, on the other hand, the accomplishment of this aim by the use of a minimum of primary concepts and relations.

—Albert Einstein

How is science based on combining observation, trust, insight and logic?

Science generally refers to the study of nature and the behavior of natural things. Inherently, this means insightful conclusions about more complex phenomena. Therefore, achieving this requires all the building blocks of understanding reality. Observation is the most basic building block allowing one person to perceive, trust essentially means people will work together, insight is clearly necessary to consider the possible answers to more difficult questions and logic is an obviously ingredient to making sense.

Science doesn't purvey absolute truth. Science is a mechanism. It's a way of trying to improve your knowledge of nature. It's a system for testing your thoughts against the universe and seeing whether they match. And this works, not just for the ordinary aspects of science, but for all of life. I should think people would want to know that what they know is truly what the universe is like, or at least as close as they can get to it.

— Isaac Asimov
