5.13 Other primary vibrators You saw in the previous two sections that stringed instruments and wind instruments possess primary vibrators that have harmonically related natural frequencies. As a result, these two classes of instruments produce notes that have a well-defined sense of pitch. In this section, I want to briefly introduce you to some primary vibrators that don't have harmonically related natural frequencies. Specifically we shall take a look at a rectangular bar, a circular membrane and a circular plat
5.11 Vibrating air column: standing waves in a conical tube The third configuration of air column that we shall consider is that enclosed by a conical tube. Figure 17 shows the normal modes of vibration for a conical tube plotted in terms of pressure. As you would expect, there is a pressure antinode at the closed tip of the cone and a pressure node at the open en
3 Sound production in musical instruments Musical instruments come in all shapes and sizes and produce an enormous variety of different sounds. Yet, with the exception of certain electronic instruments, the basic physical principles by which sound is produced are the same for all instruments – including the human voice. In this section, I shall introduce some of these principles. These will then be expanded upon over the rest of the unit. Remember I told you that when a musician plays an instrument they cause it to vibrate. T
2 What is a musical instrument? 3.3 The experiential model of learning The main proponent of this approach to learning, David Kolb, put forward a theory which he intended to be sufficiently general to account for all forms of learning (Kolb, 1984). He argued that there are four distinctive kinds of knowledge and that each is associated with a distinctive kind of learning. The four kinds of learning are: concrete experiencing reflective observation abstract analysis activ 3.2 The constructivist model of learning This model of learning concentrates on what happens during the process of learning. It identifies the central role of concepts and understandings that learners bring to new learning and the way in which new and old ideas interact. Its starting point is that learners use their existing frameworks of understanding to interpret what is being taught, and that these existing ideas influence the speed and effectiveness with which new ideas are learned. Learners are actively involved in processing w 3.4.2 Analysis of the eye-bar steel Many sections were taken of the steel near the fracture to examine its microstructure, and were compared with different parts of the same eye bar as well as with other eye bars. The sections showed a steel core surrounded by a zone that could be identified as being of higher strength due to the presence of martensite. Martensite is a strong, hard phase of steel usually formed by rapid quenching from a high temperature. XPS, X-ray photoelectron spectroscopy, gives information about Buildings of ancient Rome A tribute to the world of myth: Ovid and Holkham Hall Art history: C17th to C19th Introduction The case studies in this course introduce various typologies of heritage and the methods used to study them. The case studies help to draw attention to the fact that the heritage traditions in England, Scotland and Wales are not the same and are enshrined in slightly different legislation. Every study of heritage requires an understanding of the legal context and the traditions and history governing the object of heritage. This OpenLearn course provides a sample of Level 1 study in Introduction Reading is easy, isn't it? On any ordinary day without even noticing, you read shop signs, newspaper headlines, TV listings, a magazine, or a chapter of a paperback. So why would a message like this one appear in an online student chat room in the early weeks of a course?

Helen Langdon's Caravaggio is an attractive and well-written narrative of the life and work of an important and allegedly infamous artist. We learn about a set of artworks in a particular context and at the same time get to know a ‘new friend’ whose personality and environment seem to speak through the illustrations. The biographical structure is also a convenient way of con 3.4 Further reading Baxandall, M.

(eds) Critical Terms for Art History, Chicago and London, The University of Chicago Press, pp. 208–19. 2.7 Art, life and the interpretation of pictures David Carrier's book, Principles of Art History Writing (1991) considers the way that Caravaggio has been constructed as an artistic personality (the relevant chapter is below). The objective of Carrier's book as a whole is to demonstrate that the ‘appeal to the artist's intention adds nothing’ to the interpretation of his artworks (recall the discussion of Wimsatt and Beardsley in Author(s):
Rome: a majestic city with a rich past, spanning over two and a half thousand years. What remains to be seen of ancient Rome? As the heart of the Roman Empire, ancient Rome’s archaeological remains have been studied and admired for centuries, many being well-preserved due to their incorporation into newer structures. This album explores the sites of some of the republican temples in Rome’s Campus Martius, and relates them to the men who built them. The Roman Forum, centre of political and so
How do the themes of classical mythology come to be refashioned through the ages? Holkham Hall in Norfolk, England, is the estate of an 18th century gentleman, Thomas Coke - a scholar of epic classical authors and avid collector of the cultural beauties of the past. This album offers an opportunity to explore his house and prolific art collection, including his lavishly illustrated manuscript of Ovid's "Metamorphoses". Ovid inspired artists ranging from 2nd century sculptors to medieval illustra
This collection transports you to Europe of 1600 to 1850. Many of the foundations of European culture were being laid: commerce, arts institutions, art displays, terraced houses … even tattooing. Things we now take for granted in the fabric of our lives. Yet here we glimpse them through the eyes of a society for whom they weren’t yet set in stone. The shape of the urban environment was being defined. Yet there was a burgeoning nostalgia for all things rural, and a hunger for the trappings

What does Christopher Marlowe's Doctor Faustus tell us about the author and the time at which the play was written? This free course, Christopher Marlowe, Doctor Faustus, will help you to discover the intricacies of the play and recognise how a knowledge of the historical and political background of the time can lead to a very different understanding of the author's intended meaning.
