Noyes-Whitney Equation
Along with Willis Rodney Whitney, he formulated the Noyes-Whitney equation in 1897, which relates the rate of dissolution of solids to the properties of the solid and the dissolution medium. It is an important equation in pharmaceutical science. The relation is given by: In mathematics, one often (not quite always) distinguishes between an identity, which is an assertion that two expressions are equal regardless of the values of any variables that occur within them, and an equation, which may be true for only some (or none) of the values of any such variables. ... 1897 was a common year starting on Friday (see link for calendar). ...

Noyes was a chemistry professor at MIT and its former acting president when Hale persuaded him in 1913 to come on a part-time basis to Caltech, or Throop College of Technology, as it was then known.
Noyes had early recognized the importance of the new field of X-ray crystallography and he encouraged his former MIT graduate student C. Burdick (who was doing postdoctoral research in Europe) to go and study with William Bragg (a future Nobel laureate) in London.
Noyes was constantly on the alert for new developments and new experiments under way in England or on the continent, and equally vigilant about sending his people there to learn about them so that they could bring that expertise back to Caltech.
