Whew, the amount of brainlets and autistic /pol/tards on here.

Most of you people don't know jack shit about what you are talking, while >>9238352, >>9239191 and others are kind of right. A course on Philosophy of Science should be enough to realize that all scientific knowledge and methods are based on inductive series, and that an inductive reasoning cannot be applied with certainty to empiric facts (facts are influenced by an infinity of factors and there is no conceivable way to track them all). Thus, the idea that we "know", if we are to understand it as the idea that we can prove our hypotheses, is an impossibility. The scientific method is no more than a means to give validity to our hypotheses and thus, the idea that we can attain "scientific knowledge" is a social construct.

t. an actual scientist.

El brainlet eres tú, esto es demasiado básico y si de verdad te interesara comprender la materia, la habrías buscado por último en Google. Hay un montón de recursos mucho mejores que preguntar en /sci/ (un board en inglés, por cierto):

No voy a darte las respuestas porque eso requeriría más esfuerzo del que estoy dispuesto a hacer, y porque si no haces el ejercicio tú no vas a aprender.
