Note that the edges of these cells all connect lattice points in the structure, points with the same environments.

  Be sure that when you draw a unit cell, if you place the 'left' edge against the 'right' edge, they have the same lattice points touching!

  Covalency has to do with how polar/non-polar the bond is. The more equal a partnership, the more covalent the bond is. Thus: compare electronegativities. Metal/non-metal pairs form ionic (extreme of polar covalent to the point of being NOT covalent) bonds.

  I think that the Digolet is actually easier, and doesn't require an install. The toolbar is more powerful, and the show/hide feature is nice. Try visiting this website to see where a show/hide feature would be nice: http://mashable.com/2006/07/24/diigo-launches-nobody-cares/

Waves can take many forms, but there are two fundamental types of waves: “longitudinal” and “transverse” (see Figures 1 and 2).
- ChemPaths UW-Madison on 15 Sep 08
  
  We didn't talk about this in class, but it helps explain why some waves can't even be seen moving - like longitudinal waves in the stones during earthquakes!

  When a wave is confined to a specific place, only certain wavelengths--those that can fit the space available--are allowed. These allowed waves reflect from the boundaries of the space and the reflection reinforces the original wave (constructive interference). All other wavelengths cancel each other out by destructive interference.
