لا وجود لفئةٍ خاصة من العلوم تُسمّى العلوم التطبيقية؛ هناك العلمُ وتطبيقاتُه، وهما مرتبطان ببعضهما كما يرتبط الثمرُ بالشجرة التي أنتجته.

“There is no such thing as a special category of science called applied science; there is science and its applications, which are related to one another as the fruit is related to the tree that has borne it.”Louis Pasteur
