Hypothetical Quotes
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.)
Stephen Jay Gould
Ether is, in effect, a merely hypothetical entity, valuable only in so far as it explains that which by means of it we endeavor to explain - light, electricity, or universal gravitation - and only so far as these facts cannot be explained in any other way. In like manner the idea of God is also an hypothesis, valuable only in so far as it enables us to explain that which by means of it we endeavor to explain - the essence and existence of the Universe - and only so long as these cannot be explained in any other way. And since in reality we explain the Universe neither better nor worse with this idea than without it, the idea of God, the supreme petitio principii, is valueless.
Miguel de Unamuno
In fact, there is something puzzling about the Higgs mass we now do observe. It is generally known as the "hierarchy problem.” Since it is the Higgs mass that sets the scale for the masses of all other known elementary particles, one might guess that it should be similar to another mass that plays a fundamental role in physics, the so-called Planck mass, which is the fundamental unit of mass in the theory of gravitation. (It is the mass of hypothetical particles whose gravitational attraction for one another would be as strong as the electric force between two electrons separated by the same distance.) But the Planck mass is about a hundred thousand trillion times larger than the Higgs mass. So, although the Higgs particle is so heavy that a giant particle collider was needed to create it, we still have to ask, why is the Higgs mass so small?
Steven Weinberg
I adopt Mr. Darwin's hypothesis, therefore, subject to the production of proof that physiological species may be produced by selective breeding; just as a physical philosopher may accept the undulatory theory of light, subject to the proof of the existence of the hypothetical ether; or as the chemist adopts the atomic theory, subject to the proof of the existence of atoms; and for exactly the same reasons, namely, that it has an immense amount of primâ facie probability: that it is the only means at present within reach of reducing the chaos of observed facts to order; and lastly, that it is the most powerful instrument of investigation which has been presented to naturalists since the invention of the natural system of classification and the commencement of the systematic study of embryology.
Thomas Henry Huxley
Early on, presenter Mark Evans observes that a snake is essentially just "one massive tube with a head at the end", which, coincidentally, is also how he might describe his genitals to an audience of blind women in a hypothetical situation I've just invented in which hen nights for the visually impaired are held in special strip clubs where naked men describe their bodies in time to disco music. For what it's worth, I don't know what I'm going on about, either.
Charlie Brooker
I really was more intent on getting out of Iowa than everybody else. I just felt I didn't quite fit in exactly, the way other people did. Then I came here and discovered by living in Britain that being a foreigner is really a treat. It is such a great position to be in. When things are going well you can step forward and take part in the ceremonies and everything is great. And when things are not going well, being entirely hypothetical here, if for example your national football team got beat by Germany, you can stand back and say what a shame.
Bill Bryson
To know the quantum mechanical state of a system implies, in general, only statistical restrictions on the results of measurements. It seems interesting to ask if this statistical element be thought of as arising, as in classical statistical mechanics, because the states in question are averages over better defined states for which individually the results would be quite determined. These hypothetical 'dispersion free' states would be specified not only by the quantum mechanical state vector but also by additional 'hidden variables' - 'hidden' because if states with prescribed values of these variables could actually be prepared, quantum mechanics would be observably inadequate.
John Stewart Bell
Vampires can't exist. There'd be detailed records in the archives; they couldn't possibly evade detection by the state for any significant period. Besides which...there'd be corpses everywhere. Human blood is a poor nutrient source; it's about 60 percent plasma by volume and only provides about 900 calories per liter, so your hypothetical blood-sucking fiend is going to have to drink about two and a half liters per day. Those calories don't come in the form of useful stuff like glucose and fat: it's mostly protein from circulating red blood cells. Dracula would have to exsanguinate a victim every day just to stay alive, and would suffer from chronic ketoacidosis. The total number of intentional homicides for the whole country is around 700 a year; a single vampire would cause a 50 percent spike in the murder rate. Or they'd have to take transfusion-sized donations about two thousand times a year.
