I know I don’t get to tell you this enough, but I care about you a hell of a lot. Hank during the family intervention at the Whites’ house So, chiral, chirality, mirrored images, right? Active, inactive. Which is precisely what happened in the 1950s. But make the mistake of giving that same pregnant woman the left-handed isomer of the drug Thalidomide and her child will be born with horrible birth defects. The right-handed isomer of the drug Thalidomide is a perfectly fine good medicine to give to a pregnant woman to prevent morning sickness. But although they may look the same, they don’t always behave the same.

Well, so too organic compounds can exist as mirror image forms of one another all the way down at the molecular level. The concept here being that just as your left hand and your right hand are mirror images of one another, right? Identical and yet opposite. Walt: So the term “chiral” derives from the Greek word hand. Walt teaching his students about chirals If you’ve gone crazy or something I mean, if you’ve if you’ve gone crazy or depressed, I’m just saying that’s something I need to know about. Jesse: It’s weird is all, okay? It doesn’t compute. Jesse: Nah, come on! Man, some straight like you, giant stick up his ass, all of a sudden at age, what, 60, he’s just going to break bad? We will produce a chemically pure and stable product that performs as advertised. Jesse: You want to cook crystal meth? You? You and, uh and me? I’m thinking maybe you and I could partner up. What’s his name? Emilio? Emilio is going to prison. Jesse: You ain’t “Welcome Back Kotter,” so step off. I mean, if you’re planning on giving me some bowl-winder about getting right with Jesus by turning myself in– Jesse: Look, I don’t know what you think you’re doing here, Mr. Walt: Cap’n Cook? That’s not you? Like I said, no one is looking for you. Jesse: I don’t know what you’re talking about. Honestly, I never expected you to amount to much, but methamphetamine? I didn’t picture that. Because your heart’s in the right place, man. Walt, you got a brain the size of Wisconsin, but we’re not going to hold that against you.

Hank: Everybody listen up, listen up, listen up! I’m going to give a toast, a little toast to my brother-in-law. Hank during Walt’s birthday party at Walt’s house But I prefer to see it as the study of change. Walt: Well, technically, chemistry is the study of matter. Walt to high school students in his classroom I just want you to know that no matter how it may look, I only had you in my heart. There are going to be some things–things that you’ll come to learn about me in the next few days. To all law enforcement entitles, this is not an admission of guilt. I live at 308 Negra Arroyo Lane, Albuquerque, New Mexico, 87104. Walt speaking into camcorder in the desert
