“I don't believe that the ultimate theory will come by steady work along existing lines. We need something new. We can't predict what that will be or when we will find it because if we knew that, we would have found it already!”

— Stephen Hawking

Science Watch (September 1994)
Context: I don't believe that the ultimate theory will come by steady work along existing lines. We need something new. We can't predict what that will be or when we will find it because if we knew that, we would have found it already! It could come in the next 20 years, but we might never find it.

“Very often when we have found ourselves forever separated from what we had intended to achieve, we have already, on our way, found something else worth desiring.”

Johann Wolfgang von Goethe (1749–1832) German writer, artist, and politician

Und doch sehr oft, wenn wir uns von dem Beabsichtigten für ewig getrennt sehen, haben wir schon auf unserm Wege irgend ein anderes Wünschenswerthe gefunden, etwas uns Gemäßes, mit dem uns zu begnügen wir eigentlich geboren sind.

“We don't believe something by merely saying we believe it, or even when we believe that we believe it. We believe something when we act as if it were true.”

“The reality is; there is something which exist but what that something is; remains a question. Either because we are not capable to reveal it yet or because with time and movement it changes itself and has no truth in it. But what’s the reason for its existence without having or revealing any truth, that’s the evidence we need to find.”

Zaman Ali (1993) Pakistani philosopher

“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.”

Context: 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. As philosopher of science Karl Popper has emphasized, a good theory is characterized by the fact that it makes a number of predictions that could in principle be disproved or falsified by observation. 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.

“Science books go out of date. We throw the old one away when a newer one comes out, when we have new theories. But we don't throw away our old data; we merely interpret them differently. New theories try to account for old data (and new data) in new ways.”
