I've always been a big fan of @RadioLab but especially like when they take on mathematics. You can always count on something off from centre. In this case, the philosophy of dividing by zero featuring @karimkai & @StevenStrogatz. I've added it to my list of #math based podcasts. This and all of the rest can be found at the link

One thing I've come to on this topic is that it's really about the balance of success and challenge. And you want to start out with more success than challenge, especially for students who don't see themselves as successful in a field. Initial success fuels perseverance.
