  2. Divine Proportions: Rational Trigonometry to Universal Geometry

    en.wikipedia.org/wiki/Divine_Proportions:...

    The book was "essentially self-published" [1] by Wildberger through his publishing company Wild Egg. The formulas and theorems in the book are regarded as correct mathematics but the claims about practical or pedagogical superiority are primarily promoted by Wildberger himself and have received mixed reviews.

    en.wikipedia.org/wiki/Talk:Divine_Proportions:...

    Having attending several of Norman Wildeberger's talks, the rationale behind rational trigonometry is that the concept of an angle belongs to a circle (ie, Euler's formula), and that the concept of spread is far more natural for a triangle (c.f. Thales' theorem). Angles and distance also break down in fields other than the real numbers, whereas ...

    en.wikipedia.org/wiki/Metamath

    Metamath is a formal language and an associated computer program (a proof assistant) for archiving and verifying mathematical proofs. [2] Several databases of proved theorems have been developed using Metamath covering standard results in logic, set theory, number theory, algebra, topology and analysis, among others.

    Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.

    A well-known example is the Taniyama–Shimura conjecture, now the modularity theorem, which proposed that each elliptic curve over the rational numbers can be translated into a modular form (in such a way as to preserve the associated L-function). There are difficulties in identifying this with an isomorphism, in any strict sense of the word.

  8. List of conjectures - Wikipedia

    en.wikipedia.org/wiki/List_of_conjectures

    The following list is meant to serve as a repository for compiling a list of such ideas. The idea of the Pythagoreans that all numbers can be expressed as a ratio of two whole numbers . This was disproved by one of Pythagoras ' own disciples, Hippasus , who showed that the square root of two is what we today call an irrational number .

    Illustration for a proof of the Erdős–Anning theorem. Given three non-collinear points A, B, C with integer distances from each other (here, the vertices of a 3–4–5 right triangle), the points whose distances to A and B differ by an integer lie on a system of hyperbolas and degenerate hyperbolas (blue), and symmetrically the points whose distances to B and C differ by an integer lie on ...
