  • Incredible

    Great podcasts, incredibly interesting. Just listened to attempting to create a model of quantum gravity in the lab. Would love to hear more on that. Thank you for super listening!

  • Robots

    I’ve only admittedly listened to only one episode, but it was about the development of robots. The scientist went on and on about how great it will be when humans don’t have to do repetitive tasks and she gave an example of watching a man move a box from one place to the other. I have to laugh when people who live in cloud castles think that robots are going to make everyone happy. That guy only has the brain capacity to move boxes from one side to the other. You look in any industry, any place,... more

  • So good! And they respect your time!

    I love the variety of the guests, and Janna and Steven are great interviewers. In a podcasting world filled with fluffy 90 minute episodes, these folks keep it tight and interesting. I never find myself skipping or even speeding up the playback rate. Highly recommend!

  • Interesting topics, too simplified

    Excellent guests, but it’s a shame that they stop and explain basic math instead of keeping the talk more technical.
