This is an audio version of the Wikipedia Article: Explanatory power Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

For a statistical measure of explanatory power, see coefficient of determination or mean squared prediction error.Explanatory power is the ability of a hypothesis or theory to effectively explain the subject matter it pertains to. The opposite of explanatory power is explanatory impotence. In the past, various criteria or measures for explanatory power have been proposed. In particular, one hypothesis, theory, or explanation can be said to have more explanatory power than another about the same subject matter if more facts or observations are accounted for; if it changes more "surprising facts" into "a matter of course" (following Peirce); if more details of causal relations are provided, leading to a high accuracy and precision of the description; if it offers greater predictive power, i.e., if it offers more details about what we should expect to see, and what we should not; if it depends less on authorities and more on observations; if it makes fewer assumptions; if it is more falsifiable, i.e., more testable by observation or experiment (following Popper).Recently, David Deutsch proposed that theorists should seek explanations that are hard to vary. By this expression he intends to state that a hard to vary explanation provides specific details which fit together so tightly that it is impossible to change any one detail without affecting the whole theory.
