Eric T. Bell O. Heaviside Mathematicsis 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 seIVe 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 seIVice
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'etre of this series.
