This book is written for anybody who is intensely curious about nature and motion. Have you ever asked: Why do people, animals, things, images and empty space move? The answer leads to many adventures, and this book presents one of the best of them: the search for a precise, unified and final description of all motion.

The wish to describe all motion is a large endeavour. Fortunately, this large endeavour can be structured in the simple diagram shown in Figure 1. The final and unified description of motion, the topic of this book, corresponds to the highest point in the diagram. Searching for this final and unified description is an old quest. In the following, I briefly summarize its history and then present an intriguing, though speculative solution to the riddle.

The search for the final, unified description of motion is a story of many surprises. For example, twentieth-century research has shown that there is a smallest distance in nature. Research has also shown that matter cannot be distinguished from empty space at those small distances. A last surprise dates from this century: particles and space are best described as made of strands, instead of little spheres or points. The present text explains how to reach these unexpected conclusions. In particular, quantum field theory, the standard model of particle physics, general relativity and cosmology are shown to follow from strands. The three gauge interactions, the three particle generations and the three dimensions of space turn out to be due to strands. In fact, all the open questions of twentieth-century physics about the foundations of motion, all the millennium issues, can be solved with the help of strands.

The strand model, as presented in this text, is an unexpected result from a threefold aim that I have pursued since 1990, in the five previous volumes of this series: to present the basics of motion in a way that is up to date, captivating and simple. In retrospect, the aim for maximum simplicity has been central in deducing this speculation. While the previous volumes introduced, in an entertaining way, the established parts of physics, this volume presents, in the same entertaining and playful way, a speculation about unification. Nothing in this volume is established knowledge – yet. The text is the original presentation of the topic.

The search for a final theory is one of the great adventures of life: it leads to the limits of thought. The search overthrows our thinking habits about nature. A change in thinking habits can produce fear, often hidden by anger. But by overcoming our fears we gain strength and serenity. Changing thinking habits thus requires courage, but it also produces intense and beautiful emotions. Enjoy them!

This book is an introduction to communication theory — the theory of how humans share, encode, and decode what they know, what they need, and what they expect from each other.

This course is designed to provide students with a broad overview of the major theories on the relationship between ethnicity and politics. The course is divided into three sections. The first covers general theory and discusses the social construction of ethnicity as well as the limits of construction. The second section discusses ethnicity as a dependent variable. This section studies the forces that shape the development of ethnic identities and their motivating power. The third section addresses ethnicity as an independent variable. In other words, it focuses on how ethnicity operates to affect important political and economic outcomes.
This course is the first semester of a year-long sequence on ethnic politics. However, each semester is self-contained and students may take the course in either or both semesters. Ethnic Politics I aims for breadth over depth. It covers many works in the “canon” of texts on ethnic politics as well as addressing many major topics (modernization, entrepreneurship, prejudice, ethnic party formation, etc.) in one week sessions. Ethnic Politics II covers some of these topics in greater depth and also requires a major research paper.

This is the first lesson in the PIESM Development Concepts, Physical Development. In this lesson, there is vocabulary, notes, and two activity stations that require observations. At the end, there is a reflective peice that requires use of student observation and analysis using developmental concepts learned. 

Political Economy I explores the major social science paradigms for analyzing relations among state, economy, and society. Through readings, lectures and discussion of original texts in political liberalism and individualism, neo-classical economics, Marxism, sociological and cultural theories, and neo-institutionalism, the seminar examines the fundamental assumptions on which our understanding of the social world and our research are based.

Principles of Microeconomics is an adaptation of the textbook, Microeconomics: Markets, Methods, and Models by D. Curtis and I. Irvine, which provides concise yet complete coverage of introductory microeconomic theory, application and policy in a Canadian and global environment.

The course is an introduction to the approach of Reflective Practice developed by Donald Schön. It is an approach that enables professionals to understand how they use their knowledge in practical situations and how they can combine practice and learning in a more effective way. Through greater awareness of how they deploy their knowledge in practical situations, professionals can increase their capacities of learning in a more timely way. Understanding how they frame situations and ideas helps professionals to achieve greater flexibility and increase their capacity of conceptual innovation.
The objective of the course is to introduce students to the approach and methods of reflective practice by raising their awareness about their own cognitive resources and how they use them in their practice. The course will introduce theories of learning, knowledge generation, framing and reframing, theories of action, reflection-in-practice, and conceptual innovation, and provide students with opportunities to experiment with these theories in real life through practical exercises in which they reflect on real situations that they have faced in their past professional experience. Through these practical exercises, students will have the opportunity to reflect on their thinking capacities in the context of their practice.

The seminar is designed to provide advanced graduate students with a thorough understanding of selected regional economic theories and techniques and with experience in using alternative socioeconomic impact assessment models and related regional techniques on microcomputers. Discussions will be held on particular theoretical modeling and economic issues; linkages among theories, accounts, and policies; relationships between national and regional economic structures; and methods of adjusting and estimating regional input-output accounts and tables. Examples from the Boston area and other U.S. cities/regions will be used to illustrate points throughout the seminar. We will also examine how such models are used in other countries. New material on analyzing regional development issues will be covered.

This course develops skills in research design for policy analysis and planning. The emphasis is on the logic of the research process and its constituent elements. The course relies on a seminar format so students are expected to read all of the assigned materials and come to class prepared to discuss key themes, ideas, and controversies. Since the materials draw broadly on the social sciences, and since students have diverse interests and methodological preferences, ongoing themes in our discussions will be linking concepts to planning scholarship in general and considering how different epistemological orientations and methodological techniques map on to planning specializations.

This course surveys canonical and recent theories and methods in science studies. We will organize our discussions around the concept of “reproduction,” referring variously to:

Scientific reproduction (how results are replicated in lab, field, disciplinary contexts)
Social reproduction (how social knowledge and relations are regenerated over time)
Biological reproduction (how organic substance is managed in the genetic age)
Electronic reproduction (how information is reassembled in techniques of transcription, simulation, computation).

Examining intersections and disruptions of these genres of reproduction, we seek to map relations among our social, biological, and electronic lives.

Since its reorganisation in the 1990s, the English School has emerged as a popular theoretical lens through which to examine global events. Those who use the approach promote it as a middle way of theorising due to its ability to incorporate features from both systemic and domestic perspectives into one coherent lens. This volume, now in its second edition, brings together some of the most important voices on the English School to highlight the multifaceted nature of the School’s applications in International Relations.
