23. Point and Line Defects I (Intro to Solid-State Chemistry)
Happy Monday everyone! How you all doing? You know it's good because it's a goodie bag day  and so I'll get to what you have in your hands in this lecture. Today-- So we've been talking about  these things for a while now, right? We've built up an understanding of the stamp and the basis,  and then we understood how to talk about it like in terms of the planes and the symmetries,  and then we shined x-rays on it, and now we're going to start taking them all apart. And so don't  be sad, don't be sad, because actually that's more real-- that's more real. And that's what we'll  talk about today. So what our plan is-- you know-- So today we're going to start creating defects  in the perfect order that we've had so far. And in your goody bag you have a defect generation  machine, which we'll talk about. And then on-- And so today we're gonna talk about one kind  of defe...
