Agenda

1.  Prepared Talks

Tick Tock, by Dan Martinez

ABSTRACT.   Using Mathematica's Music package, Dan will present a
gratuitously dynamic exercise that makes his tourbillon clock audibly
"tick."

Trouble with DSolve[ ], by Dave Vasholz

ABSTRACT.   Here I discuss a very simple differential equation which =
even
Wolfram Tech Support acknowledges is completely flubbed by our beloved
software. It is further shown how, in the end, Mathematica can be used =
to
recover from its own folly.

Confirming and Generating Probability Density Functions of Two Random
Variables With Mathematica, by Mel Friedman

ABSTRACT.  Given continuous random variables X and Y having known
probability density functions, let W = g(X,Y) and Z = h(X,Y), where =
g and h
are known.  Here we use Mathematica to find the density functions of W, =
Z
and W*Z.  We also show how to use Mathematica to confirm the correctness =
of
the analytical results by simulation.

2.  Mathematica Gems and Discoveries

Sharing of Mathematica programming oddities
Applications of Mathematica to some areas of science
Something recently read and worth sharing

3.  Mathematica Questions, Possible Approaches and Discussion
