In the last hundred years, modern physics and cosmology have shown that there exist regions of the universe forever beyond our reach, hidden by truly ultimate horizons. Such regions exist in those remote parts of the universe where, from our point of view, space expands faster than the speed of light. They are found in black holes, where the gravity is strong enough to retain even light within its field of attraction. And in the realm of the very small, quarks must remain forever confined to their world of extreme density and can never be removed from it. The aim of this book is to describe these ultimate horizons, how they were discovered, how they shape our view of the world, and what clues we have about a world beyond them.

Horizons Math Kindergarten builds the foundation for the method of study that is used all the way through the Horizons Math program. Every concept follows a deliberate pattern of introduction and gradual development. Each lesson begins with a new concept or an expansion of a previously covered concept. This introduction starts a cycle of repetition and review that students will experience as they work through the lessons. Horizons Math Kindergarten lays a foundation for order and exactness. The daily practice in the student books teaches the recognition and printing of the numerals 0 to 100. Simple addition and subtraction from 0 to 10 are taught. the addition-subtraction concept is extended through 99 with the aid of counters and the number line. Counting through 100 is presented by 1's, 10's, 5's, 2's, 3's, and 4's. Principles of place value, measurement, calendar use, telling time, graphing, comparisons, and money concepts are also introduced.

Critical Conversations provides a series of theological engagements with the work of Michael Polanyi, one of the twentieth century's most profound philosophers of science. Polanyi's sustained explorations of the nature of human knowing open a range of questions and themes of profound importance for theology. He insists on the need to recover the categories of faith and belief in accounting for the way we know and points to the importance of tradition and the necessity sometimes of conversion in order to learn the truth of things. These themes are explored along with Polanyi's social and political thought, his anthropology, his hermeneutics, and his conception of truth. Several of the essays set Polanyi alongside the work of other thinkers, particularly Karl Barth, Lesslie Newbigin, Hans-Georg Gadamer, and Rene Girard, and they discuss points of comparison and contrast between the respective figures. While all the essays are appreciative of Polanyi's contribution, they do not shy away from critical analysis--and take further, therefore, the critical appreciation of Polanyi's work.
