Books
Download The Elements (Ancient Greek: Στοιχεῖον Stoikheîon) is a mathematical treatise consisting of 13 books attributed to the ancient Greek mathematician Euclid in Alexandria, Ptolemaic Egypt c. 300 BC. It is a collection of definitions, postulates, propositions (theorems and constructions), and mathematical proofs of the propositions. The books cover plane and solid Euclidean geometry, elementary number theory, and incommensurable lines. Elements is the oldest extant large-scale deductive treatment of mathematics.
Download Philosophiæ Naturalis Principia Mathematica (Latin for Mathematical Principles of Natural Philosophy), often referred to as simply the Principia, is a work in three books by Isaac Newton, in Latin, first published 5 July 1687. After annotating and correcting his personal copy of the first edition, Newton published two further editions, in 1713 and 1726. The Principia states Newton's laws of motion, forming the foundation of classical mechanics; Newton's law of universal gravitation; and a derivation of Kepler's laws of planetary motion.

Download The Mathematical Art of M.C. Escher, From the article, "He was also fascinated with paradox and "impossible" figures, and used an idea of Roger Penrose’s to develop many intriguing works of art. Thus, for the student of mathematics, Escher’s work encompasses two broad areas: the geometry of space, and what we may call the logic of space."
Download The painter who entered the fourth dimension. Did you know Salvador Dalí painted a tesseract? From the article, "Crucifixion (Corpus Hypercubus) unites a classical portrayal of Christ with a shape that only exists in mathematical theory. Dalí’s floating cross is what Banchoff describes as “an unfolded four-dimensional cube."
Download A Statistical Analysis of the Work of Bob Ross. From the article: "Now that we know the basic probabilities of individual tags, we can also find the joint probabilities of some of these events. For instance, how often do a deciduous tree and a coniferous tree appear in the same painting? We know that 57 percent of paintings contain a deciduous tree and 53 percent of paintings contain a coniferous tree. According to our data set, 20 percent of paintings contain at least one of each."
Download Macintosh "Picasso" Artwork....The famous Macintosh “Picasso” trademark logo was developed for the introduction of the original 128k Mac back in 1984. A minimalist line drawing reminiscent of the style of Pablo Picasso, this whimsical graphic implied the whole of a computer in a few simple strokes. It was an icon of what was inside the box, and became as famous as the computer it represented.

Download The Golden Ratio: Design's Biggest Myth, The golden ratioʼs aesthetic bona fides are an urban legend, a myth, a design unicorn. Many designers donʼt use it, and if they do, they vastly discount its importance. Thereʼs also no science to really back it up. Those who believe the golden ratio is the hidden math behind beauty are falling for a 150-year-old scam.

Download A Brief Taxonomy of Numbers. By Peter James. "I have spent long periods of my life working with numbers. There are many beautiful different types of these that can be constructed (or is that discovered?). The process starts with the first building blocks, the Counting Numbers, which are known more technically as the Natural Numbers. However our journey to discover the nature of numbers will take us into much less familiar territory." Peter's Website
