Starting at e 0 = 1, travelling at the velocity i relative to one's position for the length of time π, and adding 1, one arrives at 0. (The diagram is an Argand diagram .) Some mathematicians see beauty in mathematical results that establish connections between two areas of mathematics that at first sight appear to be unrelated. [ 5 ]
The aesthetic appearance is more difficult to design when a changing ambigram is intended to be shown in one way only, because symmetry generally enhances the visual appearance of artwork. Technically, there are two times more combinations of letters involved in a hetero-ambigram than in a homo-ambigram .
In visual art, pattern consists in regularity which in some way "organizes surfaces or structures in a consistent, regular manner." At its simplest, a pattern in art may be a geometric or other repeating shape in a painting , drawing , tapestry , ceramic tiling or carpet , but a pattern need not necessarily repeat exactly as long as it provides ...
A Russian mnemonic is that the waxing moon is right part of letter 'Р', which is the first letter of word растущая (growing), and the waning moon looks like 'C' which is first letter of the word стареющая (getting old). A Norwegian mnemonic is "When it looks like a comma, it's coming!"
Corner quotes, also called “Quine quotes”; for quasi-quotation, i.e. quoting specific context of unspecified (“variable”) expressions; [3] also used for denoting Gödel number; [4] for example “⌜G⌝” denotes the Gödel number of G. (Typographical note: although the quotes appears as a “pair” in unicode (231C and 231D), they ...
Whether you're heading home after the holidays or have festive plans to celebrate New Years Day, the busy holiday travel period continues, and weather may be a factor. For some, snow, rain ...
In category theory, write Hom-sets, or morphisms from A to B, as Hom(A,B) rather than Mor(A,B) (and with the implied convention that the category is not a small category unless that is said). The semidirect product of groups K and Q should be written K × φ Q or Q × φ K where K is the normal subgroup and φ : Q → Aut(K) is the homomorphism ...
Donald Trump mocked Canadian Prime Minister Justin Trudeau after his top minister’s surprise resignation following a clash on how to handle the president-elect’s looming tariffs.
