    13:59 the Latin word celeritas comes from celer, meaning swift, fast, and the suffix -tas, a Latin equivalent to our English -ty or -ness. The word celer also appears in words like accelerate. In Classical Latin the c is usually pronounced as a k.

      Syntropy is dual to increasing entropy. Syntropy is the integration, convergence or union of information to form predictions, expectations -- mutual information.
      Integration is dual to differentiation.
      Entropy is the differentiation, divergence of information into new states.
      Consciousness is an active process, you focus your attention on objects, intentionality or teleology.
      Teleological physics is dual to non-teleological physics.

    Thanks so much Brian! I love everything about the World Science Festival and this opportunity to hear discussions about the structure of the reality of our world and universe. So do we move through space/time or does space/time move through us? Some years ago, I lay on a stone bench under a russian olive tree next to a flowing river and I felt as if space/time was flowing through me. However, when I got on my bike to ride home, I felt as if I was moving through space/time. So it seems that the opposing perspectives regarding position and space/time are marvelously relative.

    I truly love the way you explain things just so precise to my cerebral cortex and neurons !!!

    What a wonderful release from current stresses. I'd love to hear about the Schrodinger equation.

    I probably would have been a lot better in math and science if I had Mr Dr Greene as an educator. To myself, the teachers just threw the alphabet into a math problem and asked me to solve.. not understanding what I’m trying to solve so my algebra level is very low. I’m now in my mid 30s and find the way he explains and articulates everything so much easier to understand and think about. This is what the internet was meant to be for.

    Dear Professor Greene, thank you so much this.I I was one of those who thought that e=mc2 was only really relevant to nuclear processes (i.e. it's what happens in the sun). Apparantly it's all around us, including every time I put the kettle on! For feedback, I'm very much they layest of the lay people, and I thought it was pitched really well for someone like me. I would say, though, that don't worry too much if some of us get lost some of the time, we're learning from the stuff we do understand, and it's a bit of a thrill to be making our own voyage into what (for us!) is the unknown

    Although I only had through high school physics +40 yrs ago, I find these videos to be both fascinating and easy to follow. My question about this equation concerns C2. Why is the speed of light squared?

    Hey Brian I just became aware of these ‘daily equations’ which are most informative and well explained, especially for a somewhat dull tool in the shed like me. I watched the most recent first then went back to E=mc^2. I’m glad that at some point you figured out the split screen thingy 😄
