Sculptures of basic mathematical functions

The calculation of percentage can be performed with
the formula p = W / G, where W stands for the relative
number and G for the whole number. The result p times
100 gives the result in percentage.

It is possible to interpret the formula as
as functional equations:
p(W,G) = W / G, W(p,G) = p G, G(W,p) = W / p.

The first and and third equation have the form f(x,y) = x / y
and the second one f(x,y) = x y. Two of the three designs
are 3D 'plots' of these functions. They can be used
in the 7th class to provide an additional view
on percentage calculation, or later as an inverse
problem: Find a function with which this shape has
been created!

The third design is a 3D 'plot' of the equation for the
kinetic energy: E(m,v) = 1/2 m v^2, with m for mass
and v for velocity.

A further application of the objects is to demonstrate
iso-lines by dipping the objects e.g. into colored water.

The objects are no "remixes", but have been inspired
