The polyhedra pages are spilt into four main
chapters. You can read the chapters simply by starting at the top, but
you can of course also pick out the subjects you might like. If
applicable the pages are linked to the puzzle section if this
Note that I have tried to keep out all kind of
mathematical formulas, so that anyone who is not familiar with
mathematics can follow the text. People interested in the mathematical
background of the polyhedra can find a lot of other stuff on the
internet. Check out the link section for more information.
This is the first chapter of this
'book' in this section is told what you can expect from these
pages. Also some general terms and definitions related to
polyhedra are captured in this chapter. Readers novice to
polyhedra may start her to get some understanding (or just go
to other pages viewing nice pictures.
Convex polyhedra are polyhedra which
are more or less spherical. Examples of these convex polyhedra
are the Platonic solids, the Archimedic solids and Catalan
solids. Also prisms, delta solids, pyramids and Johnson solids
belong to the large family of convex polyhedra
Non-convex polyhedra (or concave
polyhedra) are polyhedra which are not spherical, but more or
less star shaped. Examples of these non-convex polyhedra are
the Kepler-Poinsot polyhedra, uniform polyhedra, stellations
and compound polyhedra.
A lot of puzzlescan be reduced to a
collection of polyhedra which are ordered in some kind of
fashion. This chapter is dealing with the possibility (or
impossibility) of piling up polyhedra
This part of the website is still under
construction. Subjects in gray are not yet accessible. Please return
on a regular basis to see if there are new items added.
Second Important note: In several occasions I
have given my own interpretation on the subject of polyhedra which is
sometimes different from the general accepted 'rules'. This because I
feel that there are some gaps and inconsistencies within this subject.
In case a text is based upon my own interpretations aor fantasies,
than this text has been printed in italic. Please note that these
texts are not general truth, but just the chimeras of the author,
without any scientific or mathematical review.
