Why “Rhombus Explora”?

Well Henk and Pien both being avid Gemologists and heavily into Faceting and so on we tried to find something, anything that they could relate to and that would also be fitting of their Motorhome, easy task? NOOOOT!!!!

We thought Diamond, it being white, and as it was reborn/rebuilt, what could match, it had to resemble travel and journeys and the van and the work that was done to it??? HMMMMMM….

Suggested names were………………

Sponge-Bog Square Bus

Sponge Bob Square Bus

Van-essa

VanDiemen

DeeBill

Vantastic

Gembusta

The Haunted House

None of these quite had that “Pow” to them

We went back to gemstones, back to Diamond, Diamond in the rough……. it HAD to be something that was easily identified, easily known and short.

We looked up words, Diamond, Gemstone, Travel, Journey, Enjoyment……..

When we typed in Diamond, this is what came up.

Diamond

- An extremely hard, highly refractive crystalline form of carbon that is usually colourless and is used as a gemstone and in abrasives, cutting tools, and other applications.
- A piece of jewellery containing such a gemstone.
- A figure with four equal sides forming two inner obtuse angles and two inner acute angles; a rhombus or lozenge.

When we typed in Rhombus, this is what came up……………..

Rhombus

Main Entry – Diamond

Part of Speech – Noun

Definition – Gemstone

Synonyms – Allotrope, Bort, Brilliant, Corundum, Gem, Ice, Jager, Jewel, Lozenge, Paragon, Rhinestone, Rhombus, Rock, Solitaire, Zircon

We were onto something!!!!!!! It was very much a well known term, so we were very excited to have this name that not only was to do with the Gem world it was also a funky name! If you break it up into two words, Rhom and Bus it could almost sound like Roam – Bus, or if we add on even more to it. The Roaming Bus!!!! PERFECT!!!!!

As for travel and exploration and journey we kept going back to the word, “Explore”. What do Henk and Pien like to do the most, (other than eat) is explore!! Looking and finding and searching a seeing new things!!! Then we added a twist to make it that bit more modern day by dropping the “e” and putting in the “a” and saying “Explora”

So the Rhombus Explora would be defined as a van that is a Diamond in the rough, it was rough and now its not!! Hahahaha!! It is going to shine and sparkle like a Diamond when we are done too!

The van will roam and go to many a place, many places will be explored……Look at the van on an angle and you get a Rhombus shape!!!!!

Pretty damn cool!!!!

Below is photos of Rhombus’s that we found all over the internet

And finally just for Pien to settle the arguement on what a Rhombus is as she tells us it does not exist, despite all the evidence that we have found that it does!

Rhombus is referred to the shape of a Diamond, a Rhombohedron is made up of 6 Rhombus’s to create a Prism type shape. :)-

So the reference to Rhombus as to what we were saying is correct, we are talking about the shape of ONE FACE, she it talking about the entire shape!

Weeks later…….

So *sigh* even presenting Pien with Assher Diamond Princess cut, famous for the Rhombus, a family that Pien has a lot of dealings with, Pien still maintains a Rhombus does not exist (stubborn old woman!!), but is now calling it two more things a Rhombic and a Rombic Dodecahahedron. This is now three very different shapes she has said claiming that they are what a Rhombus is. We keep saying we are talking about ONE FACE not the ENTIRE shape. Still she remains indignant that the Rhombus does not exist and that her 17 year old dictionary tells her the truth, she is the Gemmologist and we are mere mortal idiots! She eventually tried to say it was a new shape, I think that the ancient greeks would have something to say about that! Obviously she cannot understand that she does not know everything!! LOL

## Rhombohedron

## From Wikipedia, the free encyclopedia

In geometry, a **rhombohedron** is a three-dimensional figure like a cube, except that its faces are not squares but rhombi. It is a special case of a parallelepiped where all edges are the same length.

In general the rhombohedron can have three types of rhombus faces in congruent opposite pairs.

If all of the non-obtuse internal angles of the faces are equal (all faces are same), it can be called a trigonal trapezohedron.

Another special case is that, where there is a plane of symmetry through four vertices (with symmetry group *C*_{2h}), and a special case of that, where there is another plane of symmetry through the other four vertices (with symmetry group *D*_{2h}).

The cube combines these special properties, and so is a special case of the rhombohedron.

Rhombohedrons may have their polar edges more, or less, acute than their lateral edges. The first are known as “acute rhombohedrons”, and the latter are known as “obtuse rhombohedrons”. The limiting form between these two kinds of rhombohedrons would have all of its edges similar, and would correspond to a triagnoal pyramid whose axial ratio is 1:1.2247. The interfacial angles on such a form would all be 90 degrees, and it would therefore not differ geometrically.

## Rhombic Dodecahedron

It is the polyhedral dual of the cuboctahedron, and a zonohedron. The long diagonal of each face is exactly √2 times the length of the short diagonal, so that the acute angles on each face measure cos ^{−1 }(1/3), or approximately 70.53°.

Being the dual of an Archimedean polyhedron, the rhombic dodecahedron is face-transitive, meaning the symmetry group of the solid acts transitively on the set of faces. In elementary terms, this means that for any two faces A and B there is a rotation or reflection of the solid that leaves it occupying the same region of space while moving face A to face B.

The rhombic dodecahedron is one of the nine edge-transitive convex polyhedra, the others being the five Platonic solids, the cuboctahedron, the icosidodecahedron and the rhombic triacontahedron.

The rhombic dodecahedron can be used to tessellate 3-dimensional space. It can be stacked to fill a space much like hexagons fill a plane.

This tessellation can be seen as the Voronoi tessellation of the face-centred cubic lattice. Some minerals such as garnet form a rhombic dodecahedral crystal habit. Honeybees use the geometry of rhombic dodecahedra to form honeycomb from a tessellation of cells each of which is a hexagonal prism capped with half a rhombic dodecahedron

## Rhombic

See Rhombus

Rhombic may refer to:

##
- Rhombus: A quadrilateral whose four sides all have the same length (often called a diamond).
- Rhombic antenna: A broadband directional antenna most commonly used on shortwave frequencies.

So Pien we did the homework, you don’t have to, the answer is above, we are still right!!! Hahahahahaha!!! So whats the next shape we will be thrown! Stay tuned people!
