Panel on Inflation

Series

Embed

Professor Joe Silk talks with Professor Robert Brandenberger, Professor Jerome Martin, and Dr. Dave Sloan about the current state of research and controversies surrounding inflation.

They discuss the possibility of connecting inflation to string theory and the likelihood of the initial conditions required by inflationary models. This lecture was conducted at the Dennis Sciama Theatre at the Denys Wilkinson Building, Oxford, on March 14, 2016.

Ending Poverty?

Series

Embed

Linda Yueh (Fellow by Special Election in Economics) talks about ending poverty.

The UN has a Sustainable Development Goal to eradicate extreme poverty, currently measured as people living on less than $1.25 a day, by 2030. Since 1990, 1 billion people have been lifted out of poverty. Linda argues that economic growth alone is insufficient to end poverty and discusses how economic theory may be able to help us solve the problem, particularly in Africa, to achieve the UN’s target.

What Does Philosophy Have to Do with Neuroscience?

Series

Embed

When you examine the brain, you can learn a lot and see chemical interactions, but you cannot find anything about the first-person nature of things we experience as humans, such as colours and pain.

This talk takes an introductory look at different philosophical theories relating to this – including dualism, epiphenomenalism, identity theory and externalism
Paul Skokowski is Visiting Fellow from Stanford University.
