Here is the corrected and divided text: Their coffee or tea or bagel or cookies. Okay, good morning everybody. We have dealt with reciprocal space in the last couple of lectures. Today, we will go a little bit further in that. We will be talking about structure practice and you've seen that already on one of the handouts somewhere, I think. I promise you that we will get back to them, so here we are. Structure factors are really a thing that allows you to get more than just a unit size. The unit cell size or shape from your diffraction data. So, these are very important when it comes to actually getting a crystal structure. Once again, we need to explain some convenient concepts, but the good news is this is the last time that we have to do that. Okay, so we're almost there. Originally, we introduced the concept of reflection of excess from lattice planes, right? It was a nice concept because it allowed us to come up with a very simple drawing and derive Bragg's law, which describes to us where we see diffraction, right? So we could derive Bragg's law and we could actually explain where we saw the fraction. The next thing that we introduced was we said, "Okay, it's not really a lattice plane", right? We get scattering from all of the atoms. And what we kind of then did was we made a simplified view of things by saying, "Okay, we can consider all of those atoms kind of accumulated in the lattice point, which is how we draw bright lattices", right? Where we have the dots at the corners, at the centers. It doesn't mean that the atom has to sit at just much easier for us to see what the relationship between essences....
