Heart of Darkness: The Interplay of Galaxies and Dark Matter

Series
Oxford Physics Short Talks and Introductions
Embed
A short flash talk from Peter Hatfield, Oxford Physics, who discusses the origins of the galaxies we see in our night sky and the mysterious nature of dark matter.
Galaxies are huge clusters of hundreds of billions of stars - the Milky Way is our galaxy, itself just one of many billions more. But even these are diminutive compared with the sea in which they swim, dark matter, an unknown substance we cannot see with our telescopes. We will look back in time over more than half the age of the Universe to see how galaxies sloshed about in this ocean of dark matter during their creation and development, hopefully helping us learn more about the galaxies we see today and potentially even something about the mysterious nature of dark matter itself.

Superconductivity -- alchemy for the 21st Century?

Series
Oxford Physics Short Talks and Introductions
Embed
An exciting talk and demonstration about superconductivity and its potential practical applications by Ben Williams, Oxford Physics.
Superconductivity is a weird property of some materials that has exciting applications both in the lab and outside, in new technologies. The only problem is, we don't quite know what makes superconductivity work! In this talk, you'll see superconductivity in action and find out how, just like modern-day alchemists, physicists are looking to turn the mundane into the magical!

Sea Ice Growth: Mushy layers, Convection and Brinicles

Series
Oxford Physics Short Talks and Introductions
Embed
Joe Hitchen, Oxford University Physics Department, describe the different stages of sea ice growth and the formation of hollow tubes of ice in the ocean known as brinicles.
Every year, millions of square kilometres of the Arctic ocean freeze over as sea ice forms but this growth is controlled by processes on the scale of millimetres and centimetres. At this scale, sea ice is not a pure solid but a mixture of ice crystals and concentrated brine known as a "mushy layer". I will describe the different stages of sea ice growth and the formation of hollow tubes of ice in the ocean known as brinicles.

Matter, Antimatter and The Mystery of Existence

Series
Oxford Physics Short Talks and Introductions
Embed
In this talk Nazim Hussain, Oxford University, will provide an introduction to matter and antimatter and the interplay between them.
As far as we can tell, our universe is filled with galaxies and planets (and people) all of which are made of matter. But, our universe could have been absolutely empty with nothing in it at all! In this talk, I will provide an introduction to matter and antimatter and the interplay between them. I shall also explain how the fact that we live in a universe filled with matter is one of the mysteries of modern physics, a puzzle that particle physicists are trying to resolve using the Large Hadron Collider (LHC) at the CERN laboratory.

TORCH Book Series: ‘Thomas Wyatt - The Heart’s Forest’ by Susan Brigden

Series
TORCH | The Oxford Research Centre in the Humanities
Embed
David Starkey, Chris Stamatakis and Diarmaid MacCulloch discuss ‘Thomas Wyatt - The Heart’s Forest’ by Susan Brigden as part of the TORCH Book Series
Winner of the 2012 Wolfson History Prize, 'The Heart’s Forest' is a biography of renaissance poet Thomas Wyatt, which reveals the fascinating history of his life in Henry VIII's court. His poetry held a mirror to this secret, capricious world, and alluded darkly to events which it was dangerous for him to mention. Thomas Wyatt (1503-1542) was the first modern voice in English poetry. His poetry holds a mirror to the secret, capricious world of Henry VIII's court, and alludes darkly to events which it might be death to describe. In the Tower, twice, Wyatt was betrayed and betrayer.

But this original biography is much more than a conventional life. It is an evocation of Wyatt among his friends and his enemies, at princely courts in England, Italy, France and Spain, or alone in contemplative retreat. Using new research, Susan Brigden aims to show Wyatt in all his diversity, exploring his love, faith and politics and the beginnings of Reformation England. Above all, this new biography is attuned to Wyatt's dissonant voice and broken lyre, his paradoxical inwardness and will to 'make plain' his heart, revealing a complex, elusive, endlessly fascinating figure.

Machiavelli's The Prince-500 Years On

Professor Paolo Carta, University of Trento, gives a talk for the FLJS Seminar series
Five hundred years on from Niccolò Machiavelli’s first mention of what was to become one of the most influential works of modern political philosophy, The Prince, Professor Paolo Carta last night developed a fascinating reappraisal of the inspiration and contemporary relevance of Machiavelli’s crowning achievement, bringing our events calendar to a close for the year in fitting style at Wolfson College. Professor Carta, Professor of the History of Political Thought at the University of Trento, showed that it was Machiavelli’s observation of the law in action that provided him with the inspiration to set about writing his revolutionary treatise. It was Machiavelli’s intention, he argued, to provide policymakers with a set of tools by which to exercise good political judgement, just as the law serves the judge as the basis of sound legal decision-making. Rather than referring to abstract ideals as the Greeks had done before him, Professor Carta argued that, in providing solutions to the pressing and concrete problems of a tumultuously war-torn state, Machiavelli’s The Prince constitutes a turning point in political thought. Whilst the term ‘Machiavellian’ has come to be known in terms of the skilful but underhand acquisition of and maintenance of political power at any cost, Professor Carta showed that, while Machiavelli did indeed advocate that the means justified the ends, the end in mind was always the preservation of the state rather than the individuals presiding over it at any one time. It was Machiavelli’s principal aim to show that, with power comes responsibility, and that this requires the politician to act in a way that may not appear to be what is commonly conceived of as good, in order to preserve the state. Drawing on contemporary attempts at state-building and constitution-making in Sudan and elsewhere, Professor Carta cast new light on Machiavelli’s significance for democratic accountability. Whilst he acknowledged the passages in which Machiavelli attempts to educate the Prince on the limits of force that the state is able to exercise on its people before they will revolt, he emphasized the value of the text for the preservation of democratic values, since it not only provides a toolkit for effective governance by a ruling elite, but also a means of educating the people in the criteria by which to judge the effectiveness of their leaders.
