Background
George E. Hrabovsky was employed as a Mathematica
consultant in the Department of Physics at the University of Wisconsin in
Madison between October 1997 and August 1999. Since 1991 he has been developing
Mathematica programs for use in a wide variety of applications, including
database systems, military simulations, accretion disk studies, dynamical systems theory,
and theoretical mechanics. He has also trained many people in the use of Mathematica
over the years, and he continues to assist others in learning.
In the past Mr. Hrabovsky has worked on creating interactive textbooks for advanced
undergraduate physics courses, data conversion routines, a system for generation of
Feynman graphs, fluid dynamics routines, and a system for calculating Lyapunov exponents
geometrically. While having no degrees, he does research into dynamical systems theory,
meteorology, mathematical physics, high-energy astrophysics, compact objects
(black holes, neutron stars, etc.), and relativity.
Since May 1999, Mr. Hrabovsky has been the president of Madison Area
Science and Technology (MAST), a nonprofit organization dedicated to
scientific and technological research and education. MAST is a branch
of the Society for Amateur Scientists (SAS). Current interests of MAST
include severe weather research and computational science (using
Mathematica). In 2010, MAST began the Institute for Scientific
Computing, dedicated to developing high-efficiency code for
scientific applications using Mathematica.

Consulting Case Study
Situation
Client is a research scientist at a major university.
Critical Issue
Solution of a set of renormalization group equations is required.
Why Client Is Having Difficulty
The equations are impossible (or at least prohibitively difficult) to
solve by hand.
Capabilities Needed
The client requires these solutions for frontier-level research into
supersymmetry.
Provided
The client was given expertise in coding and plotting that allowed these equations to be
solved. Then FortranForm code was generated to verify the results using a Monte
Carlo scheme.
Result
The work resulted in a published paper that contributed to a
verification of aspects of supersymmetry and also addressed a previously
unsolved problem--the so-called mu-problem. The work was completed in five
two-hour sessions.
