Lewis Carroll (1832 - 1896) is best known for 'Alice's Adventures in Wonderland'. It is less widely known that he worked as a lecturer for mathematics at Christ Church college, Oxford for 27 years. 'A tangled tale' merges his two talents as storyteller and mathematician. It consists of 10 short humorous stories which present one or more mathematical problems. The 10 'knots' as they are called, were first published in 'The Monthly Packet' magazine between April 1880 and March 1885, where readers were invited to solve the problems, and the solution was discussed in a later issue.

The golden section is a line segment sectioned into two according to the golden ratio. The total length a+b is to the longer segment a as a is to the shorter segment b. In mathematics and the arts, two quantities are in the golden ratio if the ratio between the sum of those quantities and the larger one is the same as the ratio between the larger one and the smaller. The golden ratio is a mathematical constant, approximately 1.6180339887.... At least since the Renaissance, many artists and architects have proportioned their works to approximate the golden ratio—especially in the form of the golden rectangle, in which the ratio of the longer side to the shorter is the golden ratio—believing this proportion to be aesthetically pleasing. Mathematicians have studied the golden ratio because of its unique and interesting properties. (From Wikipedia)...

Although Lieh Tzu's work has evidently passed through the hands of many editors and gathered numerous accretions, there remains a considerable nucleus which in all probability was committed to writing by Lieh Tzu's immediate disciples, and is therefore older than the genuine parts of Chuang Tzu. There are some obvious analogies between the two authors, and indeed a certain amount of matter common to both; but on the whole Lieh Tzu's book bears an unmistakable impress of its own. The geniality of its tone contrasts with the somewhat hard brilliancy of Chuang Tzu, and a certain kindly sympathy with the aged, the poor and the humble of this life, not excluding the brute creation, makes itself felt throughout. - From Lionel Giles Introduction...

The Monadology ( La Monadologie , 1714) is one of Gottfried Leibniz’s best known works representing his later philosophy. It is a short text which sketches in some 90 paragraphs a metaphysics of simple substances, or monads. What he proposed can be seen as a modification of occasionalism developed by latter-day Cartesians. Leibniz surmised that there are indefinitely many substances individually 'programmed' to act in a predetermined way, each program being coordinated with all the others. This is the pre-established harmony which solved the mind body problem at the cost of declaring any interaction between substances a mere appearance, something which Leibniz accepted. Indeed it was space itself which became an appearance as in his system there was no need for distinguishing inside from outside. True substances were explained as metaphysical points which, Leibniz asserted, are both real and exact — mathematical points being exact but not real and physical ones being real but not exact.

The Bab Ballads are a collection of light verse by W. S. Gilbert, illustrated with his own comic drawings. Gilbert wrote the Ballads before he became famous for his comic opera librettos with Arthur Sullivan. In writing the Bab Ballads, Gilbert developed his unique topsy-turvy style, where the humour was derived by setting up a ridiculous premise and working out its logical consequences, however absurd. The Ballads also reveal Gilbert's cynical and satirical approach to humour. They became famous on their own, as well as being a source for plot elements, characters and songs that Gilbert would recycle in the Gilbert and Sullivan operas. The Bab Ballads take their name from Gilbert's childhood nickname, and he later began to sign his illustrations Bab. (summary from wikipedia)

After several years working on a treatise putting forth his mechanistic philosophy and physics, Descartes shelved the project when his contemporary, Galileo, was charged with heresy. That work, The World, was only published after Descartes’ death. It seems that Descartes must have had this, in part at least, in mind when writing his more famous philosophical works. This is especially clear in the Meditations , not only in the obsequiousness of the Letter of Dedication, but also in the specific mode of argument, which does not seek merely to found science upon grounds acceptable to religious authority, but to specifically found a mathematical science; one which clearly privileges mathematical demonstrations even over common sense judgments based upon everyday and constant experience. His Copernicanism, put forth posthumously in The World, would require just such a defense. The Meditations are a central work of early modern philosophy, and play a crucial role in the conceptual development of basic perspectives and problems in the Western tradition, including substance dualism, external world skepticism, and the modern notion of the su...

Mary Everest Boole (1832-1916) was born Mary Everest in England and spent her early years in France. She married mathematician George Boole. She was the author of several works on teaching and teaching mathematics in particular. This short book, Philosophy and Fun of Algebra, is meant to be read by children and introduces algebra and logic. She uses the word “algebra” broadly, defining it as a “method of solving problems by honest confession of one’s ignorance”. Using this definition, Boole introduces, in a conversational manner, the concepts of logic and algebra, illustrating these concepts with stories and anecdotes, often from biblical sources. At times, her discussion seems somewhat mystical, speaking of the imagination and angels as messengers which guide one toward the next step in a logical investigation. Boole ends the book with a reminder that algebra’s essential element is “the habitual registration of the exact limits of one’s knowledge” and a call for the public to keep this principle in mind when encountering any situation.

As a satire, Flatland offered pointed observations on the social hierarchy of Victorian culture. However, the novella's more enduring contribution is its examination of dimensions; in a foreword to one of the many publications of the novella, noted science writer Isaac Asimov described Flatland as The best introduction one can find into the manner of perceiving dimensions.

Jules Henri Poincaré (1854 – 1912) was one of France's greatest mathematicians and theoretical physicists, and a philosopher of science. As a mathematician and physicist, he made many original fundamental contributions to pure and applied mathematics, mathematical physics and celestial mechanics. He was responsible for formulating the Poincaré conjecture, one of the most famous problems in mathematics. In his research on the three-body problem, Poincaré became the first person to discover a chaotic deterministic system which laid the foundations of modern chaos theory. He is considered to be one of the founders of the field of topology. Poincaré introduced the modern principle of relativity and was the first to present the Lorentz transformations in their modern symmetrical form. He discovered the remaining relativistic velocity transformations and recorded them in a letter to Lorentz in 1905. Thus he obtained perfect invariance of all of Maxwell's equations, an important step in the formulation of the theory of special relativity. (Summary from Wikipedia)...

This is an introduction to Einstein’s space-bending, time-stretching theory of Relativity, written by the master himself. Special and General relativity explain the structure of space time and provide a theory of gravitation, respectively. Einstein’s theories shocked the world with their counterintuitive results, including the dissolution of absolute time. In this book he brings a simplified form of his profound understanding of the subject to the layperson. In the words of Einstein: “The present book is intended, as far as possible, to give an exact insight into the theory of Relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics.” The book is challenging at times but, when approached patiently, proves itself one of the most lucid explanations of Relativity to be found anywhere.

Grace Abounding is the spiritual autobiography of John Bunyan, who also penned Pilgrim’s Progress, perhaps one of the most significant pieces of Christian literature, second only to the Bible. Grace Abounding follows Bunyan’s struggle to find true repentance and forgiveness, his battle with Satan’s temptations of unbelief, his comfort found in the Bible and his overarching victory gotten by the grace of God through Jesus Christ his Son. Readers familiar with Pilgrim’s Progress will recognize that many of the allegorical points in his famous work came out of Bunyan’s own struggles and discoveries, and it has been said that Bunyan could not have written Pilgrim’s Progress without first going through the battles chronicled in Grace Abounding.

The Annals was Tacitus' final work, covering the period from the death of Augustus Caesar in the year 14. He wrote at least 16 books, but books 7-10 and parts of books 5, 6, 11 and 16 are missing. Book 6 ends with the death of Tiberius and books 7-12 presumably covered the reigns of Caligula and Claudius. The remaining books cover the reign of Nero, perhaps until his death in June 68 or until the end of that year, to connect with the Histories. The second half of book 16 is missing, ending with the events of the year 66. We do not know whether Tacitus completed the work or whether he finished the other works that he had planned to write; he died before he could complete his planned histories of Nerva and Trajan, and no record survives of the work on Augustus Caesar and the beginnings of the Empire with which he had planned to complete his work as an historian.

Het episch dierdicht Van den Vos Reynaerde, geschreven in het Middelnederlands in de 13e eeuw, geldt als een hoogtepunt in de Nederlandse middeleeuwse literatuur. Het epos verhaalt van de schurkenstreken van Reinaert de Vos, die zo listig is dat hij iedereen weet beet te nemen. Deze vertaling uit 1885 is van Julius de Geyter. Uit zijn inleiding: Reinaart de Vos, dat meesterstuk onzer Letterkunde, bestaat uit twee deelen: het eene, dat men gewoonlijk het eerste boek noemt, is omtrent den jare 1250 in Vlaanderen geschreven door een man van genie; het zoogenaamde tweede boek , ongeveer 150 jaren later waarschijnlijk ook door een Vlaming opgesteld, is nauwelijks het werk van een man van talent. De eerste onzer beide dichters, zooals d'eposschrijvers immer deden, had al d'avonturen van zijnen held bijeengezameld, er met een meesterhand de grondstof uitgegrepen, en ze tot een kunstjuweel verwerkt. Naar zijn eigen oordeel, was zijn gedicht gansch de geschiedenis van Reinaart, wat er dan ook over dezen nog meer was geschreven of in den mond des volks voortleefde.

Naturalis Historia (Latin for Natural History) is an encyclopedia published circa AD 77-79 by Pliny the Elder. It is one of the largest single works to have survived from the Roman empire to the modern day and purports to cover the entire field of ancient knowledge, based on the best authorities available to Pliny. The work became a model for all later encyclopedias in terms of the breadth of subject matter examined, the need to reference original authors, and a comprehensive index list of the contents. The scheme of his great work is vast and comprehensive, being nothing short of an encyclopedia of learning and of art so far as they are connected with nature or draw their materials from nature. The work divides neatly into the organic world of plants and animals, and the realm of inorganic matter, although there are frequent digressions in each section. He is especially interested in not just describing the occurrence of plants, animals and insects, but also their exploitation (or abuse) by man, especially Romans. The description of metals and minerals is particularly detailed, and valuable for the history of science as being the m...
