8.3 Summary A fundamental musical and acoustical relationship is the octave. Pitches that are one or more octaves apart are heard musically as different instances of the same sound. A one-octave increase in pitch corresponds to a doubling of frequency. For musical purposes, a pitch range of one octave is divided into discrete steps, known as scales, the individual pitches of which are given letter names (A, A♭, B, etc.). The pattern of pitches in a

3.2.6 The creative cycle The creative cycle refers to the cycle of development that takes place within a single meeting of a group, as opposed to the longer-term cycle just described which may occur over many meetings. As in the case of the longer-term cycle, the creative cycle can be thought of as occurring in four phases: nurturing, energising, peak activity and relaxing (Author(s):
4.1 From awareness to understanding In this section the mathematical content is more obvious as we talk explicitly about what it means to know and to think in mathematics. We will also address your own personal knowledge in the subject. Like any other activity, doing and learning mathematics involves: using and adapting existing knowledge; acquiring and constructing new knowledge through thinking and learning; building up links that enable known t

21W.730-5 Writing on Contemporary Issues: Imagining the Future (MIT)
Turn-of-the-century eras have historically been times when people are more than usually inclined to scrutinize the present and speculate about the future. Now, the turn not just of a century but of a millennium having recently passed, such scrutiny and speculations inevitably intensify. What will the future that awaits us in this twenty-first century and beyond be like? And how do visions of that future reflect and respond to the world we live in now? In this course we will read and write about

System reliability is introduced. Other topics covered include Bayesian analysis and risk-based decision, estimation of distribution parameters, hypothesis testing, simple and multiple linear
Refuge: transforming a broken refugee system [Audio]
Speaker(s): Professor Alexander Betts, Professor Paul Collier | At this event in which they will talk about their new book, Paul Collier and Alexander Betts will discuss how the world is facing its greatest refugee crisis since the Second World War, yet the institutions responding to it remain virtually unchanged from those created in the post-war era. As neighbouring countries continue to bear the brunt of the Syrian catastrophe, European governments have enacted a series of ill-considered gest
ALPS Competency in Practice Assessment (CIPA) Tool
One of the key aims of ALPS is to improve the assessment of competence in practice across 16 professions, increasing the confidence of new graduates and their employers. The CIPA tool has been developed to establish measures of new graduate confidence in their ability across a number of areas of professional competence. Initially it is being piloted as a self-rating tool with new graduates with the intention of extending its use by employers of new graduates. The tool offers a way of establishin

Writing, Editing, and Publishing in Cybersp The Game of Kings: Medieval Ivory Chessmen from the Isle of Lewis 4.7 Summary Human activity has been responsible for some extinctions and othe deleterious changes to habitats. These changes have not always been the result of thoughtless or selfish behaviour; often intentions were worthy, but outcomes were not as predicted. The importance of genetic diversith is demonstrated here in relation to Dutch Elm disease. The need to retain genetic diversity in plants, used for food and medicine, is recognized in such initiatives as the Kew Milennium Seed Bank Appeal.

According to the United States Agency for International Development, 20 million people in developing countries require wheelchairs, and the United Nations Development Programme estimates below 1% of their need is being met in Africa by local production. Wheelchair Design in Developing Countries (WDDC) gives students the chance to better the lives of others by improving wheelchairs and tricycles made in the developing world. Lectures will focus on understanding local factors, such as operating en

A lecture on sustainable tourism
This paper addresses a new method to describe the remote collaborative design process from the perspective of reflective practice. We aim at understanding the mutual effect between internal and external structures in remote collaborative design. According to the cognitive coding
scheme of Suwa et al., we encoded the process into a set of indices?new, continual and revisited?that describe each primitive design move. In a case study which involved the authors as design collaborators, we identified
