Definitions, specification and interpretation | Arithmetic and Geometry Math Foundations 44
We discuss important meta-issues regarding definitions and specification in mathematics. We also introduce the idea that mathematical definitions, expressions, formulas or theorems may support a variety of possible interpretations. Examples use our previous definitions from elementary ge

The Triple quad formula in Universal Hyperbolic Geometry | Universal Hyperbolic Geometry 23
The Triple quad formula is the second most important theorem in hyperbolic geometry (just as it is in Euclidean geometry!) It gives the relation between the three quadrances formed by three collinear points. It is a quite challenging theorem to prove: relying on a remarkable polynomial ide

Quadrance, perpendicularity and pedal curves | Algebraic Calculus One | Wild Egg
We want to introduce metrical structure into our affine setting, allowing us to access Euclidean geometry and physical applications. To do this logically and carefully, with precise definitions, we want to take the view point of Rational Trigonometry: with quadrance and perpendicularity pl

Trigonometric dual laws and the Parallax formula | Universal Hyperbolic Geometry 32 | NJ Wildberger
This video introduces a simple universal analog (called the Right parallax formula) to the Angle of parallelism formula found by N. Lobachevsky and J. Bolyai in classical hyperbolic geometry. First we establish the dual laws of the main trigonometric laws for Universal Hyperbolic Geometry

First steps in hyperbolic geometry | Universal Hyperbolic Geometry 4 | NJ Wildberger
This video outlines the basic framework of universal hyperbolic geometry---as the projective study of a circle, or later on the projective study of relativistic geometry. Perpendicularity is defined in terms of duality, the pole-polar correspondence introduced by Apollonius, and we explain

Seminar: Some Fundamental Formulas from Metrical Algebraic Geometry
A seminar presented to the School of Mathematics and Statistics, UNSW on June 9, 2015 by N J Wildberger. This talk discusses rather elementary but surprisingly powerful formulas which lie at the base of metrical algebraic geometry. They are presented here in the affine setting, although pr

Rational trigonometry: an overview | Universal Hyperbolic Geometry 39 | NJ Wildberger
This important video introduces Rational Trigonometry from first principles using a vector approach. The main notions of quadrance and spread replace distance and angle, and are introduced purely algebraically. The scalar/inner/dot product plays an important role, and allows us to introduc

Advice to Amateur Research Mathematicians: Poly Number theory-- future directions for greater import
Number theory is a very attractive subject, but in this video we argue that for prospective amateur researchers, the chance of making an important contribution is minimal. Better to focus on a much bigger and more wide open area: Poly Number theory! Polynumbers, developed in the Algebrai

The Spread law in Universal Hyperbolic Geometry | Universal Hyperbolic Geometry 27 | NJ Wildberger
The spread between two lines in hyperbolic geometry is exactly dual to the notion of the quadrance between two points. The Spread law is the third of the four main laws of trigonometry in universal hyperbolic geometry. Its proof also relies on a remarkable polynomial identity, just as did
