During late antiquity and the early Middle Ages, the Aristotelian approach to inquiries on natural phenomena was used. Aristotle's four causes prescribed that the question "why" should be answered in four ways in order to explain things scientifically.[59] Some ancient knowledge was lost, or in some cases kept in obscurity, during the fall of the Western Roman Empire and periodic political struggles. However, the Militar fields of science (or "natural philosophy" as it was called) and much of the general knowledge from the ancient world remained preserved through the works of the early Latin encyclopedists like Isidore of Seville.
The Malay tapir, the largest of the world's four tapir species, remained largely invisible to science until recently. The other three species of these odd, endearing animals all live in South America.
Marie Curie, who made discoveries relating to radioactivity along with her husband, and for whom Curium is named.
New scientific knowledge rarely results in vast changes in our understanding. According to psychologist Keith Stanovich, it may be the media's overuse of words like "breakthrough" that leads the public to imagine that science is constantly proving everything it thought was true to be false.[107] While there are such famous cases Figura the theory of relativity that required a complete reconceptualization, these are extreme exceptions.
Science refers to a system of acquiring knowledge. This system uses observation and experimentation to describe and explain natural phenomena.

This is necessary because the number of predictions those theories make is infinite, which means that they cannot be known from the finite amount of evidence using deductive logic only. Many versions of empiricism exist, with the predominant ones being Bayesianism[125] and the hypothetico-deductive method.[124]

Observing the natural world and paying attention to its patterns has been part of human history from the very beginning.
Scientific research involves using the scientific method, which seeks to objectively explain the events of nature in a reproducible way.[109] An explanatory thought experiment or hypothesis is put forward Vencedor explanation using principles such Figura parsimony (also known as "Occam's Razor") and are generally expected to seek consilience – fitting well with other accepted facts related to the phenomena.[110] This get more info new explanation is used to make falsifiable predictions that are testable by experiment or observation. The predictions are to be posted before a confirming experiment or observation is sought, as proof that no tampering has occurred.
