The Engineering and Physical Sciences Research Council (EPSRC) has published the report it commissioned from Deloitte on the economic benefits of mathematical science research in the UK. The Council for the Mathematical Sciences (CMS) and the learned societies worked in partnership with the EPSRC and provided evidence, but the report is an independent study by the consulting firm Deloitte. The report reflects the excellence of the UK mathematics research base, and the impressive and far-reaching impact of the mathematical Sciences.
A full CMS press release is available here and the report can be accessed here.
