Mathematicians delight in finding surprising connections between seemingly disparate areas of mathematics. Whole domains of modern mathematics have arisen from exploration of such connections--consider analytic number theory or algebraic topology. Finding Ellipses is a delight-filled romp across a three-way unexpected connection between complex analysis, linear algebra, and projective geometry. The book begins with Blaschke products, complex-analytic functions that are generalizations of disk automorphisms. In the analysis of Blaschke products, we encounter, in a quite natural way, an ellipse inside the unit disk. The story continues by introducing the reader to Poncelet's theorem--a beautiful result in projective geometry that ties together two conics and, in particular, two ellipses, one circumscribed by a polygon that is inscribed in the second. The Blaschke ellipse and the Poncelet ellipse turn out to be the same ellipse, and the connection is illuminated by considering the numerical range of a $2 \times 2$ matrix. The numerical range is a convex subset of the complex plane that contains information about the geometry of the transformation represented by a matrix. Through the numerical range of $n \times n$ matrices, we learn more about the interplay between Poncelet's theorem and Blaschke products. The story ranges widely over analysis, algebra, and geometry, and the exposition of the deep and surprising connections is lucid and compelling. Written for advanced undergraduates or beginning graduate students, this book would be the perfect vehicle for an invigorating and enlightening capstone exploration. The exercises and collection of extensive projects could be used as an embarkation point for a satisfying and rich research project. You are invited to read actively using the accompanying interactive website, which allows you to visualize the concepts in the book, experiment, and develop original conjectures.

Ellipses is a literary expression that represents an implied ending. In print, it looks like this: "..." In life, on the other hand, when we find ourselves smack dab in the middle of one these implied endings, we find ourselves waiting. It's a pause far longer than a comma and can occur out of nowhere, leaving us asking, "What just happened?" and "What am I supposed to do now?" What do we do when we find ourselves in the middle of an ellipsis? Author Dave Guerrero offers us a glimpse of what to do when we face one of these ellipses in our life. Dave points out that the author and perfecter of our faith has woven these moments into our life, and it's what we do when we find ourselves here in the ellipsis that makes all the difference. Using memoirs from his own life, Dave takes his readers through his "God story" to show how the ellipsis is a crucial junction where our "so far, so God" meets "the best is yet to come." With these memoirs, Dave shows how we must find hope for the unknown and for the darkness and often pain-filled moments of the ellipsis to look forward and proclaim the promises of God who smiles at us and says, "The best is yet to come." Dave's own journey was filled with depression, cutting, cancer, eating disorders, and derailed dreams. But David shows how scripture is clear that God is always in control. As you travel through the ellipsis that he has, his prayer is that you will find hope in looking back at your God story and see the all-loving author and perfecter of your faith smiling and saying, "You ain't seen nothing yet."

The development of man's understanding of planetary motions is the crown jewel of Newtonian mechanics. This book offers a concise but self-contained handbook-length treatment of this historically important topic for students at about the third-year-level of an undergraduate physics curriculum. After opening with a review of Kepler's three laws of planetary motion, it proceeds to analyze the general dynamics of 'central force' orbits in spherical coordinates, how elliptical orbits satisfy Newton's gravitational law, and how the geometry of ellipses relates to physical quantities, such as energy and momentum. Exercises are provided, and derivations are set up in such a way that readers can gain analytic practice by filling in the missing steps. A brief bibliography lists sources for readers who wish to pursue further study on their own.

Between what is meant and what is said, between what is said and what is not conveyed, between what is conveyed and what is understood and between what is understood and what is actually meant – there are, always, ellipses. These silent spaces are home to all the poems that form this collection, which attempts to fill the void with words. Some of these poems manifest sublimated angst, while others are peace offerings. Some of them are like prayers whispered in gratitude, while others are like documentaries of bitter truths. Some come across as manifestos of new dreams, while others are just coffins for her unfulfilled desires. Covering a wide array of experiences, these poems unravel the poetry at the heart of a woman’s life’s myriad situations.

The main focus is disseminating research results regarding the pencil of ellipses inscribing arbitrary convex quadrilaterals. In particular, the author proves that there is a unique ellipse of maximal area, EA, and a unique ellipse of minimal eccentricity, EI, inscribed in Q. Similar results are also proven for ellipses passing through the vertices of a convex quadrilateral along with some comparisons with inscribed ellipses. Special results are also given for parallelograms. Researchers in geometry and applied mathematics will find this unique book of interest. Software developers, image processors, along with geometers, mathematicians, and statisticians will be very interested in this treatment of the subject of inscribing and circumscribing ellipses with the comprehensive treatment here. Most of the results in this book were proven by the author in several papers listed in the references at the end. This book gathers results in a unified treatment of the topics, while also shortening and simplifying many of the proofs. The book also contains a separate section on algorithms for finding ellipses of maximal area or of minimal eccentricity inscribed in, or circumscribed about, a given quadrilateral and for certain other topics treated in the book. Anyone who has taken calculus and linear algebra and who has a basic understanding of ellipses will find it accessible.

Rules, rules, rules! English grammar is full of rules. How are we supposed to remember when or why to use all those pesky punctuation marks? Why bother, anyway, in an age of texting and rampant emojis? When a proper foundation is laid, all forms of communication benefit: Punctuate It! gently instructs young readers (and writers) to think carefully about the marks they see and to choose their punctuation to create meaningful sentences. Vibrant, off-the- wall illustrations lend visual appeal, and Punctuation Practice sessions offer opportunities for interacting with key ideas presented in each short chapter. A brief activity closes each book. An illustrated guide to the punctuation marks known as parentheses and ellipses, including descriptions and examples of how to properly use them

Donn Byrne riddled his novel The Wind Bloweth (1922) with ellipses. For example, page 158 alone features no fewer than 27 of them. The ellipses don't merely omit superfluous words or mark pauses. Far from it! In an astonishing number of cases, the ellipses illustrate the narrative, inviting the reader to "connect the dots." What follows is an illustrated celebration of Byrne's eccentric use of ellipses. Snippets of his text are here presented in a new order, to tell a story hidden within the ellipses.

Kepler's three laws of planetary motion were a stunning development in human intellectual history. This second edition is a concise, self-contained treatment of Kepler/Newton planetary orbits at the level of an advanced undergraduate physics student. New to this edition are elements such as a detailed derivation of Newton's shell-point equivalency theorem, a revised derivation of the polar equation for an ellipse, Kepler's third law for non-inverse-square central potentials, a chapter on transfer and rendezvous orbits, and an expanded treatment of methods of calculating the average distance between the Sun and a planet. The approach is student-friendly, featuring brief sections, clear notation and diagrams, and mathematics that undergraduates will be comfortable with, accompanied by numerous exercises.

Ellipsis is the non-expression of one or more sentence elements whose meaning can be reconstructed either from the context or from a person's knowledge of the world. In speech and writing, ellipsis is pervasive, contributing in various ways to the economy, speed, and style of communication. Resolving ellipsis is a particularly challenging issue in natural language processing, since not only must meaning be gleaned from missing elements but the fact that something meaningful is missing must be detected in the first place. Marjorie McShane presents a comprehensive theory of ellipsis that supports the formal, cross-linguistic description of elliptical phenomena taking into account the various factors that affect the use of ellipsis. A methodology is suggested for creating a parameter space describing and treating ellipsis in any language. Such "ellipsis profiles" of languages will serve a wide range of practical applications, including but not limited to natural language processing. In contrast to earlier work, this theory focuses not only on what can, in principle, be elided but in what circumstances a given category actually would or would not be elided--that is, what renders ellipsis mandatory or infelicitous. A theory of ellipsis has been elusive because to produce an adequate account of this ubiquitous phenomenon one needs to address and integrate data from a wide variety of linguistic research areas. Using data primarily from Russian, English, and Polish, McShane looks at the big picture of ellipsis, integrating the syntactic, semantic, morphological, and pragmatic heuristics and bridges work on ellipsis with the larger study of reference. This is groundbreaking linguistic scholarship that bridges the theoretical and the applied, and will interest scholars in the fields of computational, descriptive, and theoretical linguistics.
