This is definitely my favorite guest. Lee Cronin is the kind of thinker I wish I could be. I bet he was a weird kid but the way his mind works, right or wrong, just makes my mind wander in a great way. I want to take whatever class he teaches.,(reply>), Cronin was my professor for biological inorganic chemistry and i'm currently taking his class on metals in medicine as part of my final year undergrad, and it's definitely strange to see him talk in this podcast as it's very different to how he delivers his lectures. He definitely comes off as more passionate about the topics discussed here even though he mentions life on mars etc. in his lectures at some points, and granted, his lectures are around an hour long as opposed to this 4 hour video but he seems way more engaged here and genuinely more interested and eager in this video than what i've seen from him before, so i've definitely got a new appreciation for how he approaches chemistry &amp; science in general now
