Any sufficiently advanced technology is indistinguishable from magic . It deals with observing and understanding the natural world. We explain how and why things happen and predict what will happen next. To gain an expanded awareness of the universe. To address the problems of modern society and their solutions. Science is based on direct experience and rational thought. Theory: well confirmed set of ideas that explains what we observe. Hypothesis: reasonable, but unconfirmed idea. (becomes theory when confirmed) Theory has predictive power, but theories are not absolutely certain. Science: a set of methods designed to describe and interpret observed and inferred phenomena, past or present, aimed aimed at building a testable body of knowledge open to rejection or confirmation. Pseudoscience: claims presented so that that they appear scientific even though they lack supporting evidence. Defined natural philosophy a branch of philosophy examining the natural world.
