We also learn about: 

I’m biggly judging, the only thing I love more than science is a weird bit, Caroline’s 4 year plan to get in a zoom call with these bozos, kind of feels like you came to the top of the mountain and came down to meet us, Brian Cox does Not follow Tom, I know something that will fix Ella’s connection, the corry-luke scale, the peripheral nervous system, free opiod receptors, endogynous, different kind of needles for that opiod, fake accupuncture, treating sever hiccups, min-maxing heroin, it’s tricky to study pain, maybe therapy works more than accupuncture, by the way I don’t need you to share everything, dolphins weren’t so great at finding land mines, I’ll just leave some dead air, an open bar for editting, the sensory deprivation tank, you’re paying for this open bar Tom, I won’t tell you the name of the paper but I will tell you about lisa simpson, was really hoping the apartment would have a dolphinarium, now do your duolingo, this was all to communicate with aliens, Tom tries to have a teachable moment, well someone was certainly “arriving”, raising a chimp as a human, Bunny’s backlash, weird studies, language is complicated and we don’t even think about it so we underestimate it, did we not all read coco transcripts in college - oh i guess not, Corry’s corona mistake, double checking even when we know someone’s wrong, can you believe there are podcasts where people try to learn everything? a meta message not about being right but about science, QI’s mistake rate, the science debunking complex can get toxic, when we debunk it’s not with antagonism but curiosity, the mould effect saga, I think what you were trying to say correy is that it’s important to foster curiosity.
