Eric T. Bell O. Hesvi.ide Mathematics is a tool for thOUght. A highly necessary tool in a world where both feedback and non linearities abound. Similarly, all kinds of parts of mathematics serve as tools for other parts and for other sciences. Applying a simple rewriting rule to the quote on the right above one finds such statements as: ´One service topology has rendered mathematical physics .. .´; ´One service logic has rendered com puter science .. .´; ´One service category theory has rendered mathematics .. .´. All arguably true. And all statements obtainable this way form part of the raison d´t!tre of this series.
