Diabetes is an increasingly common disease causing raised blood sugar with serious long-term consequences. Type 1 diabetes was almost always fatal until the discovery of insulin, and causes serious medical consequences. Type 2 diabetes, where the body does not fully respond to insulin is often associated with obesity. This lecture will consider the treatment, prevention and recent advances in the science of diabetes. The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-an... Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 2,000 lectures free to access or download from the website.

46:20 The History of Pain - Professor Joanna Bourke
Pain is often seen as universal and timeless, but how have peoples understandings of pain changed over time? Did the invention of more effective analgesics and anaesthetics really revolutionise medical practices and human relationships to suffering?
Pain forces sufferers to pay attention to their bodies. The way people-in-pain communicate their suffering has a profound effect on the type and quality of care they receive.

46:50 China: New Nation, New Art, 1911-1932 - Professor Craig Clunas
As the imperial system collapsed in China, the New Culture Movement focused debate on new categories of modernity and tradition.
This lecture was part of the 2017 Being Human Festival. For more information about the festival, please visit: http://www.beinghumanfestival.org/
For artists, it posed the questions of what it meant to be both modern and Chinese challenging them to show how ancient techniques could remain relevant. Artists began to travel abroad (to France, Japan, Germany, Britain and the USA) and become part of an increasingly international art world. The 1920s in China saw both the political chaos of warlordism, but also a flowering of creativity which drew on the keen awareness by many of Chinas potential as part of a global modernism.

57:21 What is Value in Healthcare? - Professor Martin Elliott
Value is the importance, worth or usefulness of something. In healthcare, it has been argued that the only value that matters is that to the patient.
This lecture considers this hypothesis and the relationship between clinical outcome and cost of treatment. The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-an...

Christopher Page - For Courtesan, Queen and Gallant: The Guitar in England From Henry VIII to Samuel Pepys

# playlist (click the video's upper-left icon)

Few people now remember that the guitar was popular in England during the age of Queen Elizabeth and Shakespeare, and yet it was played everywhere from the royal court to the common tavern.
In 1559 Queen Elizabeth herself received a case of three guitars as a New-Years day present.
This opening lecture of the series, with musical illustrations, will use documents, poetry and images to bring the instrument to life, with a particular focus on the autobiography of the beguiling Tudor musician Thomas Whythorne.

(русский / in Russian) Integrable models of random growth and branching graphs by Alexei Borodin

# playlist (click the video's upper-left icon)

The goal of the mini-course is to explain how representation theory helps to discover and analyze integrable structures in probability. The relevant representation theoretic constructions involve representations and characters of symmetric and unitary groups and their infinite-dimensional analogs, Schur and Macdonald symmetric polynomials, and Whittaker eigenfunctions of the quantum Toda lattice. The probabilistic counterparts are random growth models in one and two space dimensions, last passage percolation and directed polymers, solutions of the stochastic heat equation and Kardar-Parisi-Zhang equation and associated quantum many-body systems.

One aim of the course is to describe the close connections, some old and some new, between three basic parameters of a Markov chain: Mixing time, hitting time and cover time. In particular, following classical results of Aldous, recent work ([2] and independently, [3]) shows that mixing time is equivalent to the maximal hitting time of large sets. Another aim is to present some useful methods for analyzing a Markov chain, namely coupling, stationary stopping times, optional stopping for suitable martingales, and the spectrum. Key examples will include random walks on the symmetric group (card shuffling), Glauber dynamics for the Ising model, and lamplighter groups. We will also describe the connection [6] of the cover time to the maximum of the Gaussian Free Field. Open problems we will explore are (1) Diaconis’ challenge to understand which chains exhibit cutoff (an abrupt change of the total variation distance to stationarity from near 1 to near zero); (2) for Glauber dynamics, when do extra updates assist mixing, and how do random updates compare with systematic updates? (3) On a Cayley graph, for how long is the rate of escape at least the square root of t/d,where t denotes time and d is the degree? (4) On a transitive graph, is mixing time always bounded above by the diameter squared times the degree? (5) In what generality is the diameter squared divided by log(n) a lower bound for the mixing time on an n-vertex graph?References:[1] Markov Chains and Mixing Times, (2008). David A.
