“[Experimental Physicist] Phys. I cannot imagine myself perceiving non-Euclidean space!
Math. Look at the reflection of the room in a polished doorknob, and imagine yourself one of the actors in what you see going on there.”

“…the differential element of non-Euclidean spaces is Euclidean. This fact, however, is analogous to the relations between a straight line and a curve, and cannot lead to an epistemological priority of Euclidean geometry, in contrast to the views of certain authors.”

Hans Reichenbach (1891–1953) American philosopher

The Philosophy of Space and Time (1928, tr. 1957)

“If you can read and have more imagination than a doorknob, what need do you have for a 'movie version' of a novel?”

“I lock eyes with my reflection and don’t look away. The day you look away you start to lose yourself. I’m never going to lose myself. You are what you are. Deal with it or change.”

“Yes, I think I am a realist. Because I make what I see. It's only the problem of seeing it. If you can imagine a thing, conjure it up in space - then you can make it, and tout de suite you're a realist. The universe is real but you can't see it. You have to imagine it. Once you imagine it, you can be realistic about reproducing it.”

Alexander Calder (1898–1976) American artist

Question, Léger once called you a realist. How do you feel about this?

“I decided to get Ph. D. in experimental physics because experimental physicists have their own room in the Institute where they can hang their coat, whereas theoretical physicists have to hang their coat at the entrance.”

George Gamow (1904–1968) Russian-American physicist and science writer

“Some forms of Kantianism put great weight on “what we can imagine” holding that this can be a source of insight into necessary connections. Thus various of Kant’s arguments about space and time depend on the purported fact that it is impossible for us to imagine certain things: we can know, Kant claims, a priori that space has only three dimensions because we cannot imagine it as having more than three dimensions. History in the form of non-Euclidean geometry and modern physics has put paid to that particular line of argument, but in general we should beware of depending too much on “What we can imagine?,” especially in politics. As Nietzsche puts it somewhere, sometimes the fact that you can’t imagine a situation in which things are very different from the way they are now is not an especially good argument for the claim that they must be as they now are, but, rather, represents a failure of your powers about which you should feel mildly apologetic.”

“Phys. I know that it is often a help to represent pressure and volume as height and width on paper; and so geometry may have applications to the theory of gases. But is it not going rather far to say that geometry can deal directly with these things and is not necessarily concerned with lengths in space?
Math. No. Geometry is nowadays largely analytical, so that in form as well as in effect, it deals with variables of an unknown nature. …It is literally true that I do not want to know the significance of the variables x, y, z, t that I am discussing. …
Phys. Yours is a strange subject. You told us at the beginning that you are not concerned as to whether your propositions are true, and now you tell us you do not even care to know what you are talking about.
Math.”

Arthur Stanley Eddington (1882–1944) British astrophysicist

“There are times in
life when the question of knowing if one can think differently
than one thinks, and perceive differently than one sees, is
absolutely necessary if one is to go on looking and reflecting
at all.”

“When you look at Russia today, you have to try to imagine to yourself "What would a country look like if it was run by a former KGB agent?"”

Fiona Hill (presidential advisor) (1965) American policy adviser

and I think what we're seeing today, with all kinds of clandestine activity, all kinds of mysterious men … taking over Crimea, the peninsula attached to Ukraine, and affecting the situation on the ground so that later Russia can annex it — and then the kind of speeches that we've heard coming out of President Vladimir Putin about the justification of Russia's takeover or Crimea, going back into the long history of grievances against the west, dating back to the collapse of the Soviet Union, and even going back many centuries before, really, a long perspective on Russian history, this is the kind of thing you would have imagined from someone who has seen themself as a servant of the state, and as someone from an institution that sees themselves as the defender of that state. The KGB used to think of itself as the sword and the shield of the system of the state, the Soviet State — and then the Russian state after it collapsed. That is the emblem of the KGB.
