“Mathematicks and Philosophy”
John Adams believed "Mathematicks and Philosophy" fell between the science of "Politicks and War" and the art of "Painting, Poetry, Musick, Architecture." He felt his sons should study these fields, as well as "Geography, natural History, Naval Architecture, navigation, Commerce and Agriculture."
In these respective disciplines, Benjamin Franklin, Richard Gridley, and Samuel Dexter each made significant contributions to American independence and to the advancement of human knowledge.
