Calculus and Infinitesimals*

**ABSTRACT:**

*In this talk we will review a few
results from the early history of calculus where infinitesimals (or their
reciprocals) were used. Though such
results are today not regarded as rigorous, there are some insights to be gained
which might not be apparent in modern approaches. If there is time we will sketch some connections to current
research on analysis over non-archimedean extensions of the real numbers.*
