In reality the cycles we have the occasion to observe are generally not damped. How can the maintenance of the swings be explained? Have theses dynamic laws deduced from theory and showing damped oscillations no value in explaining the real phenomena, or in what respect do the dynamic laws need to be completed in order to explain the real happenings? They (dynamic laws) only form one element of the explanation: they solve the propagation problem. But the impulse problem remains.

But oppression by your Mock-Superiors well shaken off, the grand problem yet remains to solve: That of finding government by your Real-Superiors! Alas, how shall we ever learn the solution of that, benighted, bewildered, sniffing, sneering, godforgetting unfortunates as we are? It is a work for centuries; to be taught us by tribulations, confusions, insurrections, obstructions; who knows if not by conflagration and despair! It is a lesson inclusive of all other lessons; the hardest of all lessons to learn.
Thomas Carlyle
Since the universe is infinitely old, you should see some very old stars. According to the big bang theory the universe is only 13 billion years old. No stars should be older than 13 billion years. In our cosmology, stars older than this should exist. So we are on the lookout for very old stars. We made some observations [a year ago] which we are still trying to explain but the simplest explanation seems to be that there stars that are 20 billion years old.

We should observe the place, the occasion, the temper in which we find the person who listens to us, for if there is much art in speaking to the purpose, there is no less in knowing when to be silent. There is an eloquent silence which serves to approve or to condemn, there is a silence of discretion and of respect. In a word, there is a tone, an air, a manner, which renders everything in conversation agreeable or disagreeable, refined or vulgar.
François de La Rochefoucauld
Three principles - the conformability of nature to herself, the applicability of the criterion of simplicity, and the "unreasonable effectiveness" of certain parts of mathematics in describing physical reality - are thus consequences of the underlying law of the elementary particles and their interactions. Those three principles need not be assumed as separate metaphysical postulates. Instead, they are emergent properties of the fundamental laws of physics.
Murray Gell-Mann
When scientists need to explain difficult points of theory, illustration by hypothetical example - rather than by total abstraction - works well (perhaps indispensably) as a rhetorical device. Such cases do not function as speculations in the pejorative sense - as silly stories that provide insight into complex mechanisms - but rather as idealized illustrations to exemplify a difficult point of theory. (Other fields, like philosophy and the law, use such conjectural cases as a standard device.)
