Task: Text Categorization
Input (English): Anders Angstrom employed this man's namesake resonance theory to conclude that an incandescent gas emits light of the same frequency which it absorbs. He gives his name to a set of polynomials which are functions of the Bernoulli numbers, and to a function which counts all the positive integers less than and relatively prime to the argument. The general equations of motion can be derived from a differential equation named for this man and Langrange. His namesake formula relates trigonometric functions to complex exponentials. FTP, name this mathematician whose namesake constant is the base of the natural logarithm.
Output (English): Science
