The National Science Foundation and the philosophy of chemistry.

Since its founding in 1950, the National Science Foundation has provided support for a variety of studies in history, philosophy, and social studies of science. The fact that a relatively small number of projects dealing with the philosophy of chemistry have received NSF support is due to the small number of such proposals that have been submitted. The NSF Science and Technology Studies Program (STS) welcomes proposals dealing with philosophy of chemistry.
