Leonard Susslknd is one of those rare scientists who can help folks understand incredibly tough physics. He is so pure, i get high just watching his explanations! Thanks Propfessor Susskind for taking time to share with us\. And thanks Brian Greene for facilitating this wonderful interview!

[@nocancelcultureaccepted9316]

I take my hats off to Professor Greene anytime any day.

[@bilinguru]

And yet when attempting to explain it, he confesses that he "can't do it properly without a piece of paper and the equations" which is an admission that the answers are strictly mathematical and defy explanation in only words, which I find extremely frustrating, as I am not a mathmetician. Not only do I find it frustrating, but it makes me suspect that the explanation is inadequate in some way. I believe that answers must be communicable in linguistic terms. Einstein's theories, whicle are admittedly difficult to grasp at first hearing, can ultimately be understood through thought experiments, which by their very nature are metaphorical and therefore relateble linguistially.

[@steliosp1770]

Leonard is like a rockstar of physics. What a legend. Could listen to him for hours.

[@1112viggo]

yeah and with Green as an interviewer its just gold. I mean who else could just casually answer off the top of their head questions like, "how many particles are there in the universe" when his guest forgets the number and ask?🤣

[@jakelabete7412]

Leonard Susskind always succeeds in conveying the sense of struggle that he experienced while grappling with difficult matters. It takes Brian Greene to ask the right questions and then stay quiet while the explanation unfolds.

Information has mass (it can actually be weighed in some fundamental sense).
