Scientific Computing for DPhil Students

Image
Scientific Computing for DPhil Students
Nick Trefethen FRS, Professor of Numerical Analysis at Oxford University, teaches a course for DPhil (PhD) students across all the science departments at the university. The course is distinctive for its exceptionally strong conceptual basis, focussing on fundamental ideas of numerical algorithms and the world of science and engineering they sustain. Historical and philosophical notes on many subjects make these lectures unusual, offering deeper understanding and new perspectives for anyone involved with numerical analysis or scientific computing.

Book Launch: 'Citizens' Wealth'

Series
Politics and International Relations Podcasts
Embed
Author Angela Cummine gives a brief overview of her book on Sovereign Wealth Funds: what they are, and who actually owns them.
Dr Cummine then explains some of the political disagreements that can occur when the state sees itself as the primary owner of sovereign wealth, rather than the agent of the people, who she argues, are the principal-owners of these assets. It is citizens therefore, who must enjoy meaningful control over and benefit from these assets. If sovereign funds are managed and used in a way that respects this vision of them as community funds holding citizens' wealth, they could be used for a whole range of laudable public policy goals, for example, to plug budget deficits and to tackle economic inequality.
