New report: The reach and impact of mathematical sciences

  • PDF
Jan. 10, 2013 — The Mathematical Sciences in 2025, a new report from the National Research Council, finds that the mathematical sciences are an increasingly integral component of many disciplines -- including biology, medicine, the social sciences, business, advanced design, and climate studies.

However, the expanding role of the mathematical sciences over the past 15 years has not been matched by a comparable increase in federal funding, and the number of federal agencies that...
