Towards a Quantum Erlangen Program
UniverseThe classical Erlangen Program sought to classify metric spaces entirely in terms of their symmetries. In physical spacetimes, these symmetries define transformations between classical reference frames, yielding a one-to-one correspondence between frame ...

Time in Space: Velimir Khlebnikov and the “Philosophy of Hyperspace”
ArtsThis article reconceptualizes Velimir Khlebnikov’s aesthetic temporality not as a lyrical motif but as an epistemic procedure through which poetic language tests the legibility of history.

Did Lobachevsky have a model of his Imaginary geometry? [PDF]
, 2008 Lobachevsky's Imaginary geometry in its original form involved an extension of rather than a radical departure from Euclidean intuition. It wasn't anything like a formal theory in Hilbert's sense and hence didn't require anything like a model.

Some reflections on why Lobachevsky geometry was recognized
, 2013 Sometimes arguments that preceded recognition of non-Euclidean (Lobachevsky) geometry are represented in a simplified `black and white' pattern: `conservators made nonsense of genius'. Although there is something in this point of view, the real situation was more complicated, and up to some time there were decent grounds for not recognizing the ...

LOBACHEVSKY GEOMETRY – THE FIRST NON-CLASSICAL SCIENTIFIC THEORY
Вестник Тверского государственного университета. Серия: Философия, 2023 Обычно появление неклассической науки относят к началу XX в. Прежде всего имеют в виду теорию относительности, квантовую механику, излучение энергии, генетику, что совершенно справедливо. Но автор подчеркивает, что первая неклассическая теория появилась уже в первой половине XIX в. в области математики.

Nikolai I. Lobachevsky, Pangeometry
, 2010 Lobachevsky wrote his Pangeometry in 1855, the year before his death. This memoir is a résumé of his work on non-Euclidean geometry and its applications, and it can be considered as his clearest account on the subject.
