Quote by Hendrik Antoon Lorentz

“The question: 'is the Euclidean geometry true?' has no significance for Poincaré, for these is no such thing as one geometry being more true…

— Fulton J. Sheen

“Of the two alternatives - a curved manifold in a Euclidean space of ten dimensions or a manifold with non-Euclidean geometry and no extra…

— Arthur Stanley Eddington

...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…

— Hans Reichenbach

“If there is a lot of matter, gravity will cause space to curve back on itself, yielding the spherical shape. If there is little…

“There are really four dimensions, three which we call the three planes of Space, and a fourth, Time.”

— H.G. Wells

“He said that when you're a point, all you see is the point. When you're a line, all you see is the line and…

In reality the universe has no geometry.

“There are really four dimensions, three which we call the three planes of Space, and a fourth, Time. There is, however, a tendency to…

— H.G. Wells

Not that the propositions of geometry are only approximately true, but that they remain absolutely true in regard to that Euclidean space which has…

— Arthur Cayley

“This picture of matter curving space and curvaceous space dictating how matter and light will move has several striking features. It brings the non-Euclidean…

— John D. Barrow

I regret that it has been necessary for me in this lecture to administer a large dose of four-dimensional geometry. I do not apologize,…

— Alfred North Whitehead

“A consequence of Maxwell's theory of electromagnetism is that light rays move in straight lines. Thus it makes sense to use light rays when…
