What is data science? An new name for something old perhaps. Nevertheless there is something new happening. Data is being acquired in ways that coudl never have been envisaged 100 years ago. This is presenting new challenges, and ones that no single field is equipped to face. As well as the need for new methodologies and theoretical underpinnings, modern data processing is having a direct effect on our citizens in real time. In this talk I’ll suggest that data science provides a banner under which the computational and statistical sciences can unite to provide an unified response.
