Planar

Crystals in the rhombohedral lattice system are always in the trigonal crystal system, but some crystals such as quartz are in the trigonal crystal system but not in the rhombohedral lattice system.

(This refers to the six books concerned with planar geometry.)

They can be planar formations, they can be three dimensional formations.

Structure The crystal structure of AuF3 consists of spirals of square planar AuF4 units.

And what he did in Elements (especially the six volumes concerned with planar geometry),

It crystallizes in the trigonal crystal system in space group R. It is the silicon analogue of geikielite (MgTiO3).

As you can see here, they collapse from a three dimensional formation into planar formation.

As you can see here, they collapse from a three dimensional formation into planar formation.

How do you do that? You know, we're supposed to have a planar foot, so we can't get off on the springboard.

Research is ongoing to use nanowires and other nanostructured materials with the hope of to create cheaper and more efficient solar cells than are possible with conventional planar silicon solar cells.

Well the triangle inequality, and this might seem a little mundane to you, but it really shows us that we can always define a regular planar triangle based on these vectors in this way.

The following space groups have inversion symmetry the triclinic space group 2, the monoclinic 10 15, the orthorhombic 47 74, the tetragonal 83 88 and 123 142, the trigonal 147, 148 and 162 167, the hexagonal 175, 176 and 191 194, the cubic 200 206 and 221 230.

I had just done the long jump, and a guy who was missing two legs came up to me and says, How do you do that? You know, we're supposed to have a planar foot, so we can't get off on the springboard.

A pyranometer is a type of actinometer used to measure broadband solar irradiance on a planar surface and is a sensor that is designed to measure the solar radiation flux density (in watts per metre square) from a field of view of 180 degrees.
