Dear Friends, 

In view of a recent posting on a non-standard models congress, it may be of 
interest to the FOM community that infinitesimals, in the form of appropriate 
power series, are used in efficient algorithms for computing the ranges of 
functions and in describing dynamical systems ranging from supercolliders to 
checking whether an nearby-flying asteroid hits the Earth. 

For details, see webpage of Martin Berz http://bt.pa.msu.edu/berz/ and 
references therein. In particular, connection to
infinitesimals is described in the following papers:
