"The Victorians: Culture and Experience in Britain, Europe and the World 1815-1914" This was a course of free public lectures given by Richard J. Evans, Gresham Professor of Rhetoric, during the 2010-11 academic year at Gresham College. The series looks at the Victorians not just in Britain but in Europe and the wider world. 'Victorian' has come to stand for a particular set of values, perceptions and experiences, many of which were shared by people in a variety of different countries, from Russia to America, Spain to Scandinavia and reflected in the literature and culture of the nineteenth century, up to the outbreak of the First World War. The focus of the lectures will be on identifying and analysing six key areas of the Victorian experience, looking at them in international perspective. The lectures will be illustrated and the visual material will form a key element in the presentations. Throughout the series, we will be asking how far, in an age of growing nationalism and class conflict, the experiences of the Victorian era were common to different classes and countries across Europe and how far the political dominance of Britain, the world superpower of the day, was reflected in the spread of British culture and values to other parts of the world. All information about the lectures can be found on the Gresham College website: http://www.gresham.ac.uk
The lecture transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and...
1 54:10 The Victorians: Time and Space
At the beginning of the nineteenth century, communication was slow, even relatively short journeys were uncertain and time-consuming, and people were dependant on the forces of nature for energy; this lecture charts the development of new modes of communication, from the railway to the radio, the telegraph to the telephone, the steamship to the motor-car and examines their efforts on perceptions of time and space. 2 57:33 The Victorians: Art and Culture
The Victorian age began as an age of realism, in literature and art, and of nationalism and romanticism in music and culture. By the end of the century, however, the high noon of Victorian culture was starting to give way to more disturbing developments - the disintegration of musical tonality, the emergence of abstract art, the eruption of the 'primitive' into cultural styles and the arrival of modernism onto the artistic scene. This lecture examines the characteristics of Victorian culture and the reasons for its decline. 3 52:52 The Victorians: Life and Death
The nineteenth century, above all in Europe, was the age of the 'demographic transition', from high birth and death-rates to low ones; people's health improved, they lived longer, the devastating visitations of epidemics like smallpox, typhoid and cholera gradually disappeared. This lecture explores the reasons for this change, and looks at its effects on culture and society, attitudes towards death and suffering, disease, debilitation and at the end of the century, degeneracy and the Darwinian struggle for survival. 4 59:55 The Victorians: Gender and Sexuality
'Victorian' came in the twentieth century to stand for sexual repression and social convention. Personal life was governed by complex and rigid rules of behaviour. Like other aspects of Victorian culture this began to break down in the fin-de-siécle. Yet recent research, discussed in this lecture, has undermined this rather simplistic picture and begun to explore some of the contradictions and complexities of Victorian attitudes to marriage and sexuality. The place of women in Victorian culture was by no means as passive or subordinate as conventional images of the era suggest.
If there was any single belief that characterized the Victorian era it was Christian belief. Religion pervaded social and political life to an extent almost unimaginable today. Yet this was also an age of major scientific progress and discovery. Ranging from Darwin's Origin of Species to Strauss's Life of Jesus, new techniques and approaches undermined faith in the literal truth of the Bible. This lecture looks at the relationship between science and religion and attempts to explain the growth towards the end of the century of 'secularization' and 'dechristianization' in the mass of the urban population.
Science and religion came together to help shape the attitudes of the British and Europeans towards the rest of the world, whose inhabitants were increasingly regarded as socially inferior and spiritually ignorant. This lecture looks at how these ideas framed the growth of overseas Empire in the latter part of the nineteenth century, how Britain and those European states that possessed colonies governed them and what were the consequences for politics and ideology at home, above all in the growth of the Social Darwinism, racism and extreme nationalism that led to the end of the 'Victorian' era in the First World War.

1 1:04:15 Maths with Pictures
How pictures have been used in mathematics. The use of illustrations in ancient mathematics books, the invention of the first graphs and the representation of probabilities, sets and formulae by pictures. We look at the role played by computers in exploring and displaying the behaviour of extremely large and complicated problems. This has changed the culture of applied mathematics and science and influences the way research is done and the forms in which it is presented. 2 1:03:17 Continued Fractions
What are continued fractions? How can they tell us what is the most irrational number? What are they good for and what unexpected properties do they possess? How did Ramanujan make good use of their odd features to make striking discoveries? We will look at how they have played a role in the study of numbers, chaos, gears and astronomical motions.
3 1:01:22 Mathematics and the Bounce of the Superball
The commercially available 'Superball' of hard rough rubber displays many counterintuitive properties which seem to violate Newton's laws of motion. We will see that the Superball can be understood but its behaviour is completely different to a billiard ball when it undergoes collisions with a wall. We will look also at some other unusual motions of swerving and spinning balls in sports.
4 56:15 The Uses of Irrationality: Paper Sizes and the Golden Ratio
Is there anything mathematically interesting about the paper sizes we use? We will see that their range of sizes has special features that facilitates their use in Xerox machines. The standard US Letter system of sizes is different and creates problems when you want to reduce copies in size. These examples will lead us towards the special properties of certain mathematical ratios in maths, science and art.
The first digits of randomly chosen numbers arising naturally or in human affairs display surprising statistical regularities. We will see why this distribution of digits, first found by Simon Newcomb and Frank Benford, is so ubiquitous and how it has been used to check for fraudulent accountancy and for suspicious vote counts in some national elections.
Imagine that interstellar trade is possible at speeds close to the speed of light. It must incorporate the insights of Einstein's special theory of relativity, which teaches us that clocks on board a spaceship moving at high velocity will ensure time at different rates relative to clocks at the point of departure. This means that time travel into the future is possible. Which time-keeping should we use? What would happen to economics if time-travel to the past was also possible?

The English Middle Ages saw the construction of some of the world's greatest buildings, structures that still shape our towns, cities and countryside and mould our national identity. This tradition continued into modern times and beyond. These lectures give a controversial new view of how England has been built starting with the departure of the Romans and ending in the present day. These lectures were delivered by Simon Thurley, Chief Executive of English Heritage, in his role as Visiting Gresham Professor.

1 56:43 English Architecture: Making England in the Shadow of Rome, 410-1130
When the English nation rose out of the ruins of the Roman Province of Britannia, people remained obsessed with their Roman past. Seismic social and political change in 1066 barely upset the vision of patrons and architects and Rome remained England's cultural capital driving the imagination of its architects. This is a part if the series of lectures, 'God, Caesar and Robin Hood: How the Middle Ages were Built':
The English Middle Ages saw the construction of some of the world's greatest buildings, structures that still shape our towns, cities and countryside and mould our national identity. These four lectures give a controversial new view of how medieval England was built starting with the departure of the Romans and ending with the Reformation. 2 56:17 English Architecture: Reaching for Heaven, 1130-1300
During the thirteenth century Jerusalem surplanted Rome as the inspiration for English architecture. Huge national wealth led to an outburst of building of great creativity and individuality. The new gothic style which emerged by the 1220s was a national style for England creating some of the most remarkable buildings in European history.
3 59:34 English Architecture: Exuberance to Crisis, 1300-1408
England's economic success peaked in 1300 amidst a riot of architectural excess and was followed by a series of disasters which lasted much of the fourteenth century. Yet against a catastrophic background English architectural individualism flourished and out of radically changed social structures an architectural consensus emerged.
4 1:03:35 English Architecture: Coming of Age, 1408-1530
Against a background of political instability architectural initiative was captured by a new class of patrons who built in a style that expressed confidence in their worldly position and fear of the afterlife. On the very eve of the Reformation English architecture had reached a perfection that was to be destroyed by Henry VIII and new world order.
5 59:27 English Architecture: The End of the Old World Order, 1530 to 1650
The Reformation and the Civil War, two events a century apart, created an astonishing originality and independence in English Building.
6 56:08 English Architecture, 1650 to 1760: The Rise of Consensus
Opened up to the world once more England drank in influences and ideas from abroad which were to infuse English building with widely held ideas and values.
7 59:10 English Architecture, 1760 to 1830: Engine House
England's take off as the first industrial nation created a whole new language of building underpinned by technology and by an emerging view of the rest of the world.
8 58:43 English Architecture, 1830 to 1914: On Top Of The World
Economic dominance brings cultural dominance and the architecture of Empire was, in part, a template for the world. But as the century turned there were already signs of big changes which were to go on to shape the England we now live in.
9 56:09 Building the Victorian City: Splendour and Squalour
By 1900 Britain had produced the world's largest cities and the first industrial cities. These phenomena led to vast technical, social and architectural challenges. Victorian architects and engineers met these with some of the most impressive feats of construction since the cathedrals of the middle ages.
10 52:16 English Architecture and the First World War
The First World War had a devastating effect on Britain. Human and economic loss was accompanied by a loss of confidence and direction. This lecture looks at both the cultural effects of the War and its architectural impact. Both saw a struggle to reconcile a rejection of the pre-war world and a longing for it. 11 1:01:06 Forwards and Backwards: Architecture in inter-war England
The First World War brought far reaching changes to England. These included a huge expansion of the suburbs, the massive growth of motoring and a debate about how England should look in the future. This was not a simple battle between conservationists and developers; it was a search for the soul of England.
This is a part of the lecture series, English Architecture: Into the Modern World.
Simon Thurley's four lectures complete his survey of English building from the Saxons to the present day. The theme is modernity and tradition. This is the story of how British architects struggled to find an architectural language that met the needs and aspirations of a society in a state of rapid change while negotiating deep and popular traditions and beliefs. Two World Wars shook the nation producing the seemingly contradictory emotions of nostalgia and progress. Out of this has come the world in which we live. 12 49:44 Coming to Terms with Modern Times: English architecture in the post-war era
The Second World War intensified and magnified debates that had been current amongst architects since 1914. It also marks a fault line in English architectural history. Architects, supported by politicians, decisively moved away from tradition and sought to create a new language of architecture. Some loved it, but unfortunately the public grew to hate it.
This is a part of the lecture series, English Architecture: Into the Modern World. 13 48:57 The Building of England: Retrospect and Prospect 410 AD to 2000
In this the final lecture in his series on the history of English building Simon Thurley looks back. What can be concluded from a survey of 1,400 years of English architecture and social life? How English is English building and how are Saxon halls and modern skyscrapers intimately related?

4 35:00 Decoding the Heavens: Solving the mystery of the World's First Computer - Jo Marchant
In 1900 a group of sponge divers blown off course in the Mediterranean discovered an Ancient Greek shipwreck dating from around 70 BC. Lying unnoticed for months amongst their hard-won haul was what appeared to be a formless lump of corroded rock. It turned out to be the most stunning scientific artefact we have from antiquity.
For more than a century this 'Antikythera mechanism' puzzled academics. It was ancient clockwork, unmatched in complexity for 1000 years - but who could have made it, and what was it for? Now, more than 2000 years after the device was lost at sea, scientists have pieced together its intricate workings and revealed its secrets.

An investigation into the performance style required by Corelli in his Op 5 solo violin sonatas and their arrangements as concertos by his pupil Geminiani.
To be performed by a Royal Academy of Music historical performance ensemble. 2 1:03:03 London: Music under the shadow of Handel
Music by Boyce, Arne and Geminiani.
To be performed by a Royal Academy of Music historical performance ensemble.
This is a part of the series of lectures and concerts, European Capitals of Music.
Famous musical capitals provide the framework for this series of lectures with live music. The first three concentrate not only on 19th century Vienna, but on Schubert in Vienna and writing chamber music. Why did this music happen then, where was it played, who provoked, preformed and paid for it. And was it considered successful?
The final three ask similar questions of other capital cities: 20th century chamber music in Paris, baroque music in London under the shadow of Handel, and virtuoso violin playing in Rome focused on Corelli, the 300th anniversary of whose death is being celebrated this season.
The works in each programme are played by present members of the Royal Academy of Music. 3 1:00:04 Paris: Debussy and Ravel
Debussy's Sonata for Flute, Viola and Harp is contrasted with Ravel's very different Sonatine for the same combination.

The lecture is punctuated by musical examples and followed by a full performance of the piece, played by Florian Mitrea and Alexandra Vaduva. 7 1:01:21 The Challenge of the Solo: The Baroque Violin - Christopher Hogwood & Pavlo Beznosiuk
Pavlo Beznosiuk, one of the world's leading baroque violinists, explains and demonstrates the challenge of music for solo violin; works by Nicola Matteis and Heinrich Biber lead to a discussion and performance of the famous Chaconne from Bach's Solo Partita in D minor. Can such a work be satisfactorily analysed or does "music begin where words leave off"? 8 55:02 The Opening Salvo: Beethoven's String Quartet in F major - Christopher Hogwood & the Wilhelm Quartet
A talk and performance of Beethoven's String Quartet in F major, Op. 18 No.1
By Professor Christopher Hogwood and the Wilhelm Quartet
How to be revolutionary without scaring away your public? How to announce yourself as a new broom without alienating the more stalwart connoisseurs?
Beethoven faced these problems when presenting his first six string quartets for publication as opus 18; did he win his public and allay their fears with his choice of opening?
The Wilhelm Quartet presents the evidence.
The Wilhelm Quartet comprises:
- Marciana Buta (violin)
- Charlotte Skinner (violin)
- Daisy Spiers (viola)
- Hetty Snell (cello)
9 53:28 Is it possible? - Mozart's Oboe Quartet in F major, K.370
A lecture and performance on Mozart's Oboe Quartet in F major, k.370
by Christopher Hogwood, with Mea Wade and players from the Royal Academy of Music.
Harnessing virtuosity to good taste and fireworks to fine craftsmanship is a permanent challenge for the composer. Purely technical show will have little lasting effect, and Mozart was especially scrupulous at linking what sounded effective with what was musically needed. We examine with Mea Wade the requirements of good oboe playing and some of that instrument's special qualities, and hear a performance of the quartet with players from the Royal Academy of Music.
The quartet comprises Mea Wade (oboe), Eleanor Corr (violin), Richard Waters (viola) and Antonio Novais (cello).
10 54:12 Remember Me: Pachelbel, Purcell and Fauré
An analysis of what makes the following music masterpieces: Pachelbel's Canon, Purcell's Dido's Lament, and Fauré's Violin Sonata.
Memorability is sometimes achieved by the simple technique of repetition, in addition to more high-flown inspiration. Some of the simplest sustaining devices of great music are ground bass, ostinato or chaconne; this lecture shows that a canon can be more than simply "Three Blind Mice".
Professor Christopher Hogwood, Gresham Professor of Music, with players from the Royal Academy of Music
The choice of instrumental grouping can make or break a composition; the string sextet, a notoriously difficult combination, takes on a forward-looking guise with Strauss in probably the most exquisite of all music designed to be played off-stage, while Brahms looks back to the baroque with his solutions: sonority is the key.
Six players from the Royal Academy of Music offer the live experience: Kiann Chow and Charlotte Skinner (violins), Rhoslyn Lawton and Ana Monteverde (violas), Amy Jolly and Romain Lapeyre (cellos).
The art of being succinct is not one always associated with the works of Bach; in his compact setting of the Magnificat he employs economy and symbolism to illustrate each verse in a few minutes of music which challenge the reader of "de-code" the full message.
13 1:02:15 From Printed Page to Performance - Christopher Hogwood, Emma Kirkby and Jakob Lindberg
When so much in music education is formulated on the principle of imitation, and the passing down of received 'traditions' from teacher to pupil, it is important to readdress the significance of original and informed opinion in performance.
Dame Emma Kirkby, who has done more than any other musician of our generation to reassess the vocal approach to earlier music will discuss with the Lecturer her approach to singing, teaching, recording and performing and the effect her performances have had on singing world-wide over the last forty years.
The lecture is illustrated by live examples taken from Renaissance lute songs and other repertoire, including the following pieces:
Musical notation is both inexact and changeable; the assumptions of one period may be lost on following generations, and the greater part of written music still remains unpublished at the present day. The challenges of editing and presenting a text, either of a well-known classic or of an unknown writer differ in music from those faced in the similar worlds of literature or Biblical criticism. The dilemmas created by composers' second thoughts and revisions, and disciples' 'improvements' require a 'correct' way of presenting obsolete information to the modern performer and raise questions which can both change our attitude to familiar works and resurrect forgotten treasures.
15 1:09:57 The Authenticity of Genius - Christopher Hogwood with players from the Royal Academy of Music
Although Mozart is the usual example of genius that springs to mind (a combination of youth and perfection), in this lecture Felix Mendelssohn is proposed as a more precocious example of the same qualities, with an even greater range of abilities (painting and languages in addition to both composing and performing). As a test case we will examine his Octet for Strings, Op. 20, written at the age of sixteen and performed for this lecture by players from the Royal Academy of Music.
16 1:00:00 Classical Music: Fakes, Completions and the Art of Borrowing
Although Mozart's unfinished Requiem is the most publicised composition requiring a helping-hand, there are many similar incomplete may-be masterpieces which have been assisted in some way, plus a number of well-loved classics which have very little connection with their supposed author ('Albinoni's Adagio' heads such a list). In addition composers of all periods have been open to the 'art of borrowing' - Handel was particularly active in this area and the reasons and results of his 'borrowings' shed a new light on some very familiar compositions.
18 49:46 The Past is a Foreign Country
In its passage from manuscript composition to audible performance, a musical work passes through the hands of editors, teachers, interpreters, recording engineers and many others, all of whom make decisions, often based on personal choices, and have to satisfy the tastes and needs of a changing public. With over a century of recorded sound as evidence, we can now assess the options and expectations of the modern performer, and measure these against the evidence available to the interpreter today, and the range of choices to be made.
source: Лекториум 2013年6月16日 Спецкурс призван заполнить один из самых одиозных пробелов в общем образовании, возникающих у студентов мат.-меха. после общих курсов. Все геометрические объекты, которые изучаются в этих курсах (скаляры, векторы, ковекторы, линейные отображения, скалярные произведения, алгебры и т.д.) являются примерамитензоров. Между тем, имеются столь же важные геометрические объекты, которые тензорами не являются, а именно, спиноры. Нам кажется, что повернув объект на 360^o вокруг какой-то оси, мы возвращаем его в исходное положение. Но электрон твердо знает, что при этом он не возвращается в исходное положение, так как меняется проекция его спина. С точки зрения электрона группой симметрий этого мира является вовсе не ортогональная группа, а ее односвязная накрывающая, спинорная группа. В курсе планируется систематически изложить классическую теорию алгебр Клиффорда (являющихся широким обобщением внешней алгебры) и спинорных групп, доказать основные структурные теоремы, классификацию над классическими полями и т.д., и рассказать о некоторых приложениях. Это абсолютно фундаментальные общеобразовательные вещи, знание которых совершенно необходимо всем, кто специализируется по алгебре, геометрии, топологии, и математической физике. Ну и, разумеется, в особенности тем, кто конкретно интересуется алгебраическими или конечными группами, простыми алгебрами, теорией представлений, однородными многообразиями, и т.д. Планируется, что основная часть материала будет понятна САМЫМ МАЛЕНЬКИМ, начиная с 1-го или 2-го курса, но многие аспекты (явное задание спинорных групп уравнениями, обобщения на формы старших степеней и т.д.) могут быть новыми и для взрослых, включая аспирантов.
