# The Playsome Threesome: Maxima, Maple, and Mathematica

In this section we shall play with three lovely ladies, Maxima, Maple, and Mathematica. Of these Maxima is a little underdressed perhaps, but a discerning eye will notice lovely tidbits and morsels under her scanty rag. You will find that their accents, phrasing and pronounciation may differ a little, and yet their native tongues are close enough, so that you can understand one, while mastering the language of the other. All three can please a gentleman, and all three can frustrate him too. Their moods are capricious like April weather.

In the second part of the section we shall consign all three damsels to hard labour in the kitchen of our castle. The task will be to derive formulae for fitting. This task will let us appreciate respective strengths and shortcomings of each and every wench.

Once the formulae have been derived we shall employ them to educe the Hubble Constant, which is related to the expansion of the Universe, from experimental data of Sandage and Tamman.

This section contributes to points 5c and 3 of the Syllabus (cf. Section 1.1).
