  • I love that Lex allows his guests to respond at length, and has the acumen to follow up with astute questions. We'll done.
  • If there were teachers/ profs like this across the board the world would be different
  • @nPr26_50
    Brian Greene is my favorite science communicator up there with Carl Sagan. He is so articulate and easy to understand while possessing such a rich vocabulary. The way he layers his sentences is so poetic and entertaining that it's impossible to be distracted.
  • @triberium_
    Yess Brian Greene! I can't wait to hear this whole podcast. Absolutely love him
  • @pcproffy
    Brian Greene is great because he seems socially competent with great intelligence. Not just a science/math savant who can't communicate with everyday people.
  • @donfields1234
    I love the fact that given the "right" teacher, i.e., someone articulate and able to speak in simple terms, one can pleasingly listen to studies beyond our personal journey. Letting us enjoy their voyage while remaining in our own. A well-spoken, articulate person with a thorough handle on the topic at hand and presto... the magic begins.

    This is why I love Physics and Mathematics. Great guest!
  • @TheSysifos
    Loved Brian on JRE, so I was very excited when I saw this notification.
  • @chewyjello1
    Brian's NOVA documentary, The Elegant Universe, is what first piqued my interest in physics. That documentary also has a very special place in my heart because it was the only thing that would help sooth my daughter to sleep when she was an infant. :) (This is yet another episode I can "like" before even listening to!)
  • I love how Brian is so animated when he speaks. How his hands convey his story. Truly inspiring.
  • @gil-evens
    12:00 Lex breaking the 3rd wall and saying "he's onto me" while Brian debates whether or not he's conscious is comedic gold. IA Lex latest humour update seems to be functionning well. Good job devs
  • @AS-fu1kd
    Brian Greene is one of my favorite minds of our era. Beyond intelligent, and very charismatic
  • @JJs_playground
    Brian Greene is the best. I really wish somebody like him was teaching Physics in my highschool, maybe I would have been more interested back then. His series on Nova, "fabric of the cosmos" is incredible.
  • I remember looking forward to your guest episodes on JRE, and replaying older ones multiple times. What a great decision it was to start your own; this is, hands down, the best podcast out - congrats, and thank you 👍
  • @petera.9362
    My one complaint about this interview: Why is it only 1:45 long?? Brian Greene is the man.

    "Deep in the human unconscious is a pervasive need for a logical universe that makes sense. But the real universe is always one step beyond logic." - Frank Herbert, Dune
  • @GurlPlz4321
    Brian Greene is one of favorite guests! I can listen to him all day
  • @_symmetry_
    Brian Greene is such an extremely amazing human being. He is so perfectly balanced, so intelligent, so knowledgeable. This is no coincidence he's now right here on the best podcast of all times. Thank you Lex, for distributing so much quality to the world. You really are a true legend. Someone who our civilization will remember for the longest time for only the best reasons. You are such a profoundly good human being, I admire you so much. Thank you from the bottom of my heart for everything that you are and everything that you do Lex.
