Explanation Definition and 982 Threads

An explanation is a set of statements usually constructed to describe a set of facts which clarifies the causes, context, and consequences of those facts. This description may establish rules or laws, and may clarify the existing rules or laws in relation to any objects, or phenomena examined.Explanation, in philosophy, is a set of statements that makes intelligible the existence or occurrence of an object, event, or state of affairs. Among the most common forms of explanation are causal explanation; deductive-nomological explanation, which involves subsuming the explanandum under a generalization from which it may be derived in a deductive argument (e.g., “All gases expand when heated; this gas was heated; therefore, this gas expanded”); and statistical explanation, which involves subsuming the explanandum under a generalization that gives it inductive support (e.g., “Most people who use tobacco contract cancer; this person used tobacco; therefore, this person contracted cancer”). Explanations of human behaviour typically appeal to the subject’s beliefs and desires, as well as other facts about him, and proceed on the assumption that the behaviour in question is rational (at least to a minimum degree). Thus an explanation of why the subject removed his coat might cite the fact that the subject felt hot, that the subject desired to feel cooler, and that the subject believed that he would feel cooler if he took off his coat.

    How can Schrödinger's Cat be both alive and dead?

    Can some one explain to me how the cat can be both alive and dead, I get the principle that since we don't know it is both at the same time because we don't know but in reality it's either alive or alive we just don't know, it's the human factor of sentience just because we don't know doesn't...

    What is most likely to be the actual explanation of gravity?

    I am studying general relativity and quantum physics at the moment and as you know each theory has a different explanation for gravity and now the string theory has a different one too (afaik) so what is most likely to be the actual explanation of gravity? General relativity seems very logical...

    Pulse Width Modulation explanation

    I have read a lot of articles on pulse width modulation and I am none the wiser as to how it generates different voltages by simply varying the pulse width of the waveform.

    Explanation of common calculus examples

    Work (J) =\int Force(N) .dx(m) I understand this one, work done = force * distance moved in direction due force, but the force can change in magnitude or direction so less/more component of the force is in the direction of movement, so in this case the area under the graph of force vs distance...

    In-Depth Pascal's Law Explanation

    Problem: The general idea makes sense intuitively to me, but most sources I've found cite Pascal's Law merely as scientific fact with not much explanation. What I'm wondering is why pressure applied at one point in a fluid is transmitted undiminished to all other points? Is it a concept due...

    Physical explanation of velocity time dilation

    In SR, pure relative velocity between two observers causes a time dilation between them. It seems that if the two observers were at rest w.r.t. each other at some point in time, then the one who accelerates to achieve the relative velocity is the one who gets time dilation (i.e. comparatively...

    [Basic question] What is the 'physical' explanation of a division by a fraction?

    For example, dividing by 2, means we cut something in two. But dividing by 0.5, can only be explained with multiplying something by 2. So, is there a "physical" explanation of dividing by 0.5? Is it "I divide by an entity that internally multiplies' or something as so bizarre?
