Hey Everyone--Slow network speed is creating a delay. Episode will be available in a few minutes. Not quite relativity but things can take unexpected amounts of time.

thank you so much for your time Dr.Greene, hope you provide us with the mathematical derivation videos, and looking forward for the upcoming equations.

Hello, can you talk about physical laws simplifying in higher dimensions.

[@firstdawn108]

I really love to learn science and work as scientist. Please, help me out.

[@carolinaribeiro6868]

boltzmann's equation for entropy!

[@stevenrobertson6656]

Definitely !

[@hyperduality2838]

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.

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.

So accelerate should really be pronounced '..asskelerate' 😁

Maths and physics were the two subjects at school I found the most difficult. But I just love how communicators like Brian make it accessible to those like me who have no science background and stimulates my interest in these subjects.

Anybody can understand a well presented explanation. But not everyone can actually do the math which constitutes the true understanding of the concepts being explained. Most people love learning stories and facts about space but don't want to learn or perform math.

I had to write the following on my Facebook page together with a general link to the world science festival page. If you've always dreamed of being able to read the equations of physicists as an eye-opener, like Shakespeare's sonnets, Rumi's poetry, or a section of James Joyce's Finnegan's Wake, here's an opportunity to lift a tab of the veil into that world. A daily introduction by Brian Greene to one of the central equations of physics that lets us, mathematical illiterates, know the depth of this symbol mystery. A nice little morning gift here in our isolation.

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.

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.

Dear Prof. Greene, I'm a 66 years old quantum chemist also familiar (enough) with relativity and particle physics and biochemistry. Some 6 years ago I struggled through Einstein's field equations; unfortunately, the stuff fades away quickly if you don't do regular exercises. My primary interest is above all in the underlying brain behind that all. So I'm a really happy christian who loves to enter into discussions with "atheists". I count you among the friendliest representatives of a naturalistic world view; perhaps that is why I mention you so often in my local church community. I am looking forward to the discussions with you! Maybe a tip for the audience. It is best to learn the material through simple exercises. I highly recommend the instructional videos from Lenny Susskind. Greetings from the sunny side of Germany: Ludwigshafen, Rheinland-Pfalz!
