Lee Smolin - Why is the Quantum so Strange?

To know reality, one must confront the quantum. It is how our world works at the deepest level. What's the quantum?

[sharmitoboylos]

one of the many amazing things about this series is how brilliant Robert has to be even to talk with these folks and keep asking them the right questions! Sometimes they look at him like, How did you understand what i just said well enough to ask me that follow-up?

[JAYDUBYAH]

A quite smart and educated man interviewing a humble and careful genius.

[DuncanEduardo]

What I'm always amazed by is that the great thinkers of the past, including right up to early 20th century with Einstein, were more or less working with pen, paper and deep thought. No computers or advanced machinery. They didn't have the huge advantage of deep space astronomical evidence or massive computational power. Of course one could argue that theory starts on paper versus the application coming later.

Wow. What a time to be alive; to have this info in the palm of our hands.

Why so few subscribers? This is a fantastic channel.

[patinho]

If you tube had existed when I was younger I would have seen these guys as heroes and wanted to be a physicist. No doubt

[gdsm]

I feel like this channel desperately needs a marketing overhaul and perhaps a video design one as well. It may not be *absolutely* necessary but it'd REALLY help the channel grow, improve and evolve. A few ideas off the top of my head include adding another interviewer (for video diversity), figuring out something original to add to each interview (maybe a certain question you ask everyone), and creating a new series of videos.

You usually produce amazing content with very interesting/unique interviews with people most have never heard of before, on topics many never have adequately explained to them. Anyway, just the thoughts of a longtime subscriber.

at 8:23, "which is composed of what exactly" .. friends that was priceless!

Geometro Genesis - the creation of the Geo Metro.

Sounds much better than String Theory. How does it handle Dark Matter (or, rather, the problem that Dark Matter theory proposes to answer)?

[mxbishop]

Coming up with a theory of quantum gravity that is testable, and also figuring out why quantum entanglement works the way that it does - are, in my opinion, the two areas that will drive the next great leap in theoretical physics. Loop Quantum Gravity has an edge, in my view, because it is studying the emergence of space and time - whereas string theory, as originally conceived, starts with space and time as a given. Hopefully, we'll see some interesting experimental results in our lifetime - that points toward one theory or the other.

I wonder if there is a difference between the "large" and "the small" in that beyond a certain "smallness" (Plank?), it's similar to entering a black hole in which the rules are 'bent' toward quantum mechanical physics. The trick then would be to look at the warping of time and space at this horizon... i.e. to find the scale at which the laws change... ?

[theroboticscodedepot]

Fascinating! Matter is also an emergent property so perhaps this idea is really onto something.

[sngscratcher]

The quantum SEEMS so "strange" to us because we deluded ourselves into believing that we know what this reality is, based on our observations of the macro world. It is important that we don't allow our minds to become "trapped" in any dogmatic worldview or belief system, be it religion, materialism, etc.

Took me couple of time of listening to the intervju before i got it. Maybe thats why few subs

"Space is dynamical, which evolves, just like anything else building" - Lee Smolin

He said it in a nonchalant manner, with a straight face, and somehow the conversation kept going without a glitch or pause and, more importantly, without a question from the interviewer.

[myroseaccount]

WHAT?


Somebody run that by me again. It's almost as if a thunderbolt landed next to me in the High Street and nobody seemed to notice

[KaliFissure]

There is a classical model which will supplant QM. Photons physically are the entire probability sphere. An electron shell implodes and creates a low pressure shockwave which propagates at c in all directions. Which atom is in the right condition to absorb/detect that wave is the question. The resonant chamber has to be the right size. 

There is also a physical process which maintains fine tuning. Each neutron which contacts event horizon becomes vacuum energy and then Hamiltonian for Hamiltonian re emerges in lowest energy points of space.  Conservation.

Event horizons are one way pressure release valves venting energy pressure from highest energy pressure conditions to lowest energy density points of space.

[KokoRicky]

The interviews with this guy are seriously interesting, I've been hobbyist researching quantum mechanics for years yet still found some interesting nuggets after listening.

[DrakeLarson-jspx]

Lee's down a semi 'rabbit hole' without inversion physics!!... and has not listened to Edward Teller compared to other academics in this field!! I suggest that Lee not examine 'Spin-Network' - but look to geophysics super-rotation of the inner core data (Mary Fowler's input) and Rob Clarke's wisdom...
