Lily is a Great Dane that has been blind since a bizarre medical condition required that she have both eyes removed. For the last 5 years, Maddison, another Great Dane, has been her sight. The two are, of course, inseparable.”

I know these photos have been reblogged to death but that first one, with Lily nudging her buddy, did me in.

Any physical theory is always provisional, in the sense that it is only a hypothesis - you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory. On the other hand, you can disprove a theory by finding even a single observation that disagrees with the predictions of the theory. […] Each time new experiments are observed to agree with the predictions, the theory survives and our confidence in it is increased; but if ever a new observation is found to disagree, we have to abandon or modify the theory.
