[edit] Deleted redirect
I've removed the redirect and started a new article. This needs a bit of more work, please feel free to edit (although I think the mathematical formalism should be kept to a minimum).O. Prytz 22:16, 9 January 2006 (UTC)
[edit] Errors in diagrams
Unfortunately all of the diagrams showing three angles here are wrong. The angle gamma as shown can be calculated from the angle alpha since they are both part of the same quadrilateral, whose angles must sum to 180 degrees. New diagrams with the angles in the correct places are needed. --Chymicus 19:33, 24 July 2006 (UTC)
[edit] Is anyone planning to DEFINE Bravais lattices???
This article has one of the most deficient definitions among all mathematics articles. There are 14 Bravais lattices in what sense? In other words, what makes two Bravais lattices equivalent? Without this information, the article may as well be chicken scratchings.Daqu 15:52, 28 November 2006 (UTC)
Furthermore, the description of the different kinds of Bravais lattices makes great use of the word cell without once mentioning what cell is being discussed.
Lastly, please note the the expression "a ≠ b ≠ c", used repeatedly in describing various diagrams, does not exclude the possibility a = c.Daqu 16:00, 28 November 2006 (UTC)
- I believe that wikipedia articles are by definition "works in progress". If you are knowledgeable in this area, perhaps you can pitch in and do the necessary? --Rifleman 82 16:12, 28 November 2006 (UTC)
[edit] Monoclinic lattice images
I've replaced images for Monoclinic lattices from Monoclinic.svg to Monoclinic.png / Monoclinic-base-centered.svg to Monoclinic-base-centered.png. Maybe the png version of these are more correct in the description of their angles. -- Anonymous
- I'm an idiot. Images have now been corrected, and will go back to the SVG versions. Thanks for pointing this out. Stannered 14:33, 18 March 2007 (UTC)
