1 57:41 The River Thames and its Architecture
The Thames is the reason that London is where it is and the river has had a decisive influence on the growth of the city since Roman Times. For 500 years it was the only reliable way to move about but in the sixteenth and seventeenth centuries changes came that were to alter the face of London and transform our relationship with the river.
This event is part of Totally Thames 2017 that runs from 1-30 September

2 57:22 House, Shop and Wardrobe in London's Merchant Community
During the Middle Ages, London was home to one of the largest and richest merchant communities in the world. These men and their families invested heavily in fine architecture both for business and pleasure.
In the first of two lectures with the theme Merchants, Money and Megalomania, Simon Thurley will unearth the lost mercantile buildings of medieval London and show how influential they were.

4 58:22 London Merchants and Their Residences
During the Middle Ages London was home to one of the largest and richest merchant communities in the world. These men and their families invested heavily in fine architecture both for business and pleasure.
Simon Thurley, Visiting Professor of the Built Environment unearths the lost mercantile buildings of medieval London and shows how influential they were.
5 55:08 Palace, Park and Square: St James's and the Birth of the West End
Based on new research into the origins of St. Jamess, Simon Thurley looks into the ingredients that went into making a court quarter there and the way it formed a blueprint for the new West End of London.
This is the first of two lectures by Professor Thurley on Buildings in the West End of London.
6 51:06 The Birth of Modern Theatreland: Covent Garden and the Two Theatres Roya
London is home to two of the oldest working theatres in the world both founded by Charles IIs patents. They shaped a whole quarter of London, and continue to do so today. In a second lecture on Buildings in the West End of London,
Professor Thurley looks at the significance and impact of these great institutions on the development of London.

1 54:46 Cleaning Up The Thames: Success or Failure?
The Thames is often hailed as an international success story. Engineering works solved 19th century sewage problems, improving Londoners' health. Salmon, otters and birdlife are now reported to be flourishing along the Thames and the waterfront has been reinvigorated with new buildings. On the other hand, Thames Water PLC has been heavily fined for environmental offences that compromised human health, contaminated land and affected ecosystems. Levels of chemicals in river water are high. Will the Thames Tideway tunnel solve flooding and pollution?
2 59:54 Organic Food: Rooted in Lies?
Organic food production is environmentally benign, better for animal welfare, has human health benefits and tastes better - or so say its proponents. Conversely, detractors allege that the rising global population cannot be fed without using artificial fertilisers, herbicides and pesticides, that the environmental impact is slight and manageable, and that organic consumers are being duped by farmers.
With a global market approaching 70 billion, there's a lot at stake. Including some blind taste tests, the environmental science evidence behind organic farming will be reviewed, exploring facts and debunking a few myths.
3 58:00 EcoTowns or EgoTowns?
A sustainable solution to the UKs housing crisis, or a flimsy excuse for high-profile, profitable construction activity in the green belt? Architects may love them, but most ecologists are sceptical. Eco-town proposals have attracted controversy, with local residents alleging that their environment will be irrevocably damaged with the arrival of sprawling new estates, thousands of cars and the loss of important wildlife habitats.
Drawing upon live audience opinion, the lecture will weigh up the evidence for and against ecotowns.

5 1:02:58 National Parks and National Park Cities
National Parks were designated to protect some of the worlds most loved landscapes from being eaten away by industrial and housing development. But Britains National Parks are exploited by intensive agriculture and sucked dry of their water for neighbouring cities. They sustain non-native invasive species and unlike National Parks elsewhere in the world, they are not natural parks. A movement is emerging with the aim of developing Greater London as the worlds first National Park City. But is there any significant environmental advantage to this and would London benefit from becoming one?
6 55:02 Is 'Green Business' a Contradiction in Terms?
Posters in shops and on trucks shout carbon neutral business, and more organisations are boasting of reducing their environmental impact by using environmentally-friendly, responsibly sourced materials. And yet we also have diesel car emission frauds, the hoax of degradable plastic, and a fashion industry that claims to be sustainable whilst suggesting that we buy new clothes each season.
There are green marketing scams, and dubious data being deployed to benefit shareholders. Are global businesses now leading politicians in moving towards more sustainable practice or is this an example of a post-truth society?

2 50:03 Homer's Iliad via the Movie Troy (2004)
Homers Iliad, the earliest Greek poem, narrates the archetypal war between Europeans and Asiatics divided by the Hellespont. Looking at Wolfgang Petersons blockbuster Troy (2004), the lecture describes the genesis of the Iliad between the Mycenaean Late Bronze Age and the 8th century, when it was first written down with the aid of the new, phonetic script adapted from the Phoenician civilisation of the Levant. It explores the poems plot, tragic perspective on the human condition, and the despair caused by untimely death on an immense scale.
3 54:01 The Age of Tyrants: Sappho via Gounod's Opera
The heroine of Charles Gounods French opera Sapho (1851) sings her last aria O My Immortal Lyre on a Greek cliff before plunging to her death. Sappho, the most famous poet of the Lyric Age of Greece, in the 7th to 6th centuries BC, addressed passionate love poems to women.
This lecture uncovers what we know about the real Sappho, an aristocrat who lived between 630 and 570 BCE on the island of Lesbos and socialised in the lavish courts of upstart tyrants. This historical context in no way diminishes her songs astonishing immediacy and erotic power.
4 51:44 Slave Stories: Aesop and Walter Crane
In 1887 the influential arts-and-crafts book illustrator Walter Crane published The Babys Own Aesop, bringing the homespun wisdom of ancient Greek peasants to a new generation of children. This lecture uses these fables to tackle the least attractive feature of ancient Greece - institutionalised slavery. Beneath the semi-legendary figure of Aesop himself, a barbarian sold to a Greek slave-owner in the 6th century BCE, lie tens of thousands of his real-life equivalents.
The lecture asks how the ancient fables address power relations in a slave society. Were they primarily stories for and by slaves, or did they serve ruling-class interests?

1 48:04 Shakespeare's London and Ancient Rome
William Shakespeare spent his schooldays learning Latin. When he arrived in London and became an actor and playwright, he discovered a city and a culture that modelled itself on ancient Rome.
Jonathan Bate tells the story of how and why Shakespeare was steeped in the classics, from his earliest plays such as Titus Andronicus and The Comedy of Errors to his dramatisations of the stories of Julius Caesar and Antony and Cleopatra.
2 49:01 Shakespeare's Heroes
What do we mean by a hero and where does our understanding of the heroic idiom come from?
In this lecture, Jonathan Bate will show how Shakespeares idea of the hero was shaped by the classical tradition, going back to the ancient tale of Troy and Virgils epic poem The Aeneid. But in Hamlet and Troilus and Cressida we meet a Shakespeare who was profoundly sceptical about the heroic ideal.
3 51:51 Shakespeare's Lovers
William Shakespeare made his name as a poet before he became famous as a playwright. His erotic poem Venus and Adonis was the most popular work of literature of the Elizabethan Age, while its dark companion piece The Rape of Lucrece set the mould for Shakespeares exploration of the tragic consequences of sexual desire turning to violence.
Jonathan Bate will show how Shakespeare developed these themes from his reading of the great Roman poet Ovid.
4 48:10 Shakespeare's Politics
It is well known that Shakespeare lived in an age of monarchy and wrote powerfully in his English history plays about the duties of the sovereign.
In this lecture, Jonathan Bate will tell another, forgotten story: of how Shakespeare was also fascinated by Roman political models, especially the theory of civic duties expounded by Cicero, who appears as a character in Julius Caesar. He will also show how Shakespeare looked to Horace for a model of the public role of the writer.

6 50:32 Shakespeare's Ghosts and Spirits
Where do the ghosts in Shakespeare come from? And what about the magic? In this lecture, Jonathan Bate will summon up the ghosts of Old Hamlet, the victims of Richard III and Julius Caesar, revealing their origins in the bloody plays of Seneca. He will then show how such figures from classical mythology as Theseus and Medea provide a key to the association between supernatural powers and Shakespearean art.

1 54:51 English Landscape: The Picturesque
The late eighteenth and early nineteenth- century vogue for the Picturesque and for forging an English landscaping tradition (with frameable landscape scenery and managed wildness) will be the starting point for discussion.
Proponents of the Picturesque, preferring to explore British scenery rather than go on the European Grand Tour, explicitly cultivated notions of Englishness and stress the native elements in landscape scenery, such as castle or abbey ruins (real or folly) in grand gardens, not classical temples.

3 50:58 English Landscape: Constable and Clare
Constable's Stour landscapes of the Regency period, during and just after the War with France, and his publication English Landscape Scenery, champion local and low-key rural England.
John Clare's vernacular poetry in the same period celebrates the kind of rural scenery that escapes the notice of those for whom the paintings of Claude or Poussin are the ideal of landscape. Both Constable's and Clare's localism springs from a very powerful emotional connection with the idea of 'home'.
4 51:16 Samuel Palmer and the Pastoral
Samuel Palmer, in his Shoreham period in the 1820s and 30s, seized on the long tradition of classical pastoral landscapes, and wrested it into an English idiom. He effectively naturalised a foreign import, bringing an idyll to life in a Kentish valley, with sheep, shepherds and cornfields under a harvest moon, and the village church nestling in the fold of the hills.

Branching Random Walks and Maxima of Gaussian Free Fields | Ofer Zeitouni
# playlist (click the video's upper-left icon)
source: Лекториум 2013年7月16日
The model of branching random walks, and its close relative branching Brownian motion, describes the evolution of particles that undergo both random motion (diffusion) and branching. The analysis employs a mixture of analytical tools (the KPP equation, recursions, monotonicity) as well as probabilistic ones (changes of measures, first and second moment methods, large deviations), especially in dimension 1, to which this mini-course will be devoted. The classical main results are due to Fisher and Kolmogorov-Petrovsky-Piscounov, as well as McKean and Bramson.There has been much recent progress concerning fine properties of the leading particles, as well as in exploiting the link with other problems involving random walk, and in particular cover time. Of particular interest is the link with a class of Gaussian fields called the (discrete) Gaussian free field, in dimension 2.These lectures will present an introduction to both Branching random walks and Gaussian free fields. A rough plan is the following:
1) Definition of branching random walks, law of large numbers, recursions, tightness of maxima via the Dekking and Host argument, first and second moments methods, location of maximum. Introduction to the genealogy of the front. Inhomogeneous media and phase transitions.
2) Rough tree structures and cover times.
3) Gaussian free fields on graphs: definitions, fluctuations of maxima, basic inequalities (Borell-Tsirelson, Sudakov-Fernique). Subsequences and tightness: the Dekking-Host argument revisited. An introduction to the Dynkin isomorphism theorem.
4) Tightness of maximum for the 2D Gaussian free field: link with modified branching random walks, fluctuations.
5) Discussion of open problems.курс прочитан в рамках St. Petersburg School in Probability and Statistical Physics
