Sir Roger states his mathematical view of cosmology with endearing eloquence and confidence, without playing the celebrity card. A brilliant, generous, humble gentleman who clearly loves the challenges of independent thought and sharing knowledge.

I love this guy. There may never be another Roger Penrose (although I hope that, in future, there will be many). A unique, fascinating, enjoyable, brilliant man of genius.

His book "The Road to Reality" is no less than a complete mathematical physics course. It's almost unbelievable how good it is at the exposition of tricky thinking and more advanced methods in mathematics. I love that he treats readers and his audiences like curious and intelligent human beings instead of 'talking down to the plebeians' as so many science presenters do.

In our scientific age, Roger Penrose is one of those personalities who are like secular priests because he asks the biggest and most directly relevant questions about the universe and especially consciousness that many physicists shy away from, even other superstars like Hawking.

Awesome job folks, you have a very interesting collection of talks. I do hope you continue to post english language talks in future. Penrose is as thought provoking as ever.

Roger Penrose is a gift to humanity.

Good sound, good video, extraordinary content. Highly recommended!

Very rare, Roger without transparant sheets. Extraordinary. :-)

Thank you for all your efforts. I appreciate lack of translation as well. Good luck to everybody in the new year 2017. By the way: to jest naprawdę jeden z najlepszych portali. "Portalów" to niepoprawnie po polsku, ale po Sylwestrze nie można mieć pretensji. Jedno błędne słowo nikomu nie zawadza.

He belongs in that line of distinguished teachers of physics and mathematics, and much else, which includes Bertrand Russell and Richard Feynmann et al.

One of the few secular physicists who I can trust because he refuses to accept contrarieties/contradictions. If we gloss over these we've given up on the project of science. (Several years ago Sean Carrol was wavering on the axiom of casualty - heck he'd have to give up on the axiom that assumes the truth of axiomatic truths, but then anything goes).

Awesome lecture!!

Piękna grecka, filozoficzna metoda odkrywania praw fizyki. oparta na rozumie Doświadczenia z czasem też będą. Gratuluje.

When RP is using his familiar acetate OHP illustrations, he can look at the sheet on the projector in front of him and talk easily. How is it progress to have him wrestling with a not-especially-sensitive buttoned controller and craning his neck up, unable to see the writing at the top? The whole IT setup in that theatre is poorly implemented. The data should be in front of him, so he can point to parts of the image on the display he can easily see. To give a man in his 80s the setup we see here is a technically misconceived cybernetic nightmare.

Absolutely brilliant guy.

Q&A: How about consciousness? I can tell you (... only this) about it and I should talk about physics I think from this point onwards. I love it! (1:33:33....)

I also find it not convincing: first one has to choose with which class of functions one works (smooth, analytic, continuous, measurable). In the measurable setting in fact everything is the same: there is only one up to isomorphism standard probability Borel space without atoms (the interval [0,1] with Lebesgue measure). As far as I know people working with Loop Quantum Gravity work with measurable functions (I have seen this as an objection against LQG since their ,,loops'' are measurable maps from the circle-but the image of a circle by measurable map may look completely different from circle-but in fact the same is true even for continuous maps i.e. Peano curve). But what I wanted to stress: if you work with ANALYTIC functions then the smaller the set the larger class of functions: this is because being analytic is a condition for a convergence of a power series and such a series could be divergent in some bigger region being still convergent in the smaller one. There are theorems supporting this point of view: two analytic functions which are the same on a set with accumulation point are in fact identical. For smooth (or continuous) functions the situation is completely opposite: one can define smooth functions locally and then glue them together so in some sense the larger the region the more smooth functions you admit. Finally one can adopt the point of view of Fourier series: any square integrable function on a interval is determined by its Fourier coefficient and then this really comes down to ,,counting'' and this point of view ignores the size of the space on which functions are defined. Of course there are many detils here (working with open or closed sets, allowing functions to oscillate, on unbounded domains one no more has Fourier coefficient) but I think that all these details somehow support my position that the argument is not convincing.

Basically what he says is if we had a higher spacial dimensions like the 25 number string theorists claim, we would inevitably see it's effects dominate the night sky. Maybe too difficult to observe on earth. We don't have nearly enough of the energies needed to excite a particle to act upon a higher dimension, but the universe has ample energy. Milkyway has enough to spare. Supermassive black holes have the energy as well. So far it hasn't been observed, and they've been looking for a long time now.

Interesting: if you a high Number of Dimensions of Space, the Number of Components of the Field - say Electric, Gravitational, - on that Space is irrelevant! Now I may combine this Information with some other Insight I found in one of Alexander Polyakov's Papers. But more about that later, Roger. Kaluza - Klein, yes. Functional Freedom is in the Space Dims,rather than Time. Extra - Dimensions have the same issue of not being Elements of Functional Freedom. So Penrose wonders how String People give Extra Dims Compactification Shapes etc...One Quantum exited in Extra - Dim is not concerned with the Locality . It involves the whole Universe! What does that mean? QM works too well in the Domain of Physical Parameters and for the Phenomena "we" have tested observed. Scandinavian History Interlude: Hans Christian Andersen. Mermaid. Bohr's Famous Statement: Quantum Measurement = Irreversible Act of Magnification. Quantum World = Unitary Evolution. Notice Roger : You presuppose! that Quantum System's Behvior before Measurement and the Mathematical Method by means of which you describe it : are necessarily identical! What do you mean by Quantum Superposition of Gravitational Fields? Be more specific/concrete.

1:29:14 - So, is this scale factor not relevant to entropy? A really loose way of stating the CCC idea is to say that once the last black hole evaporated, and there's nothing left in the universe but photons, the universe "forgets its big." After all, he's postulating that it just kind of "bangs again" from that point. So if we could step outside the universe at watch this, we'd see each successive universe be vastly larger than the previous ones. But only by some sort of "God like" measuring stick that we could somehow maintain across cycles. Within the universe, it seems like the fundamental building blocks are going to be "much larger" on successive cycles. But even though the Planck length for cycle N+1 would be huge compared to that of cycle N (measured by this "God ruler"), it still represents the same fundamental limiting quantity in the context of the new evolving universe. So it seems to me like a lot of stuff my have to get "reset," and it's not unreasonable to me that one of them might be the "scale" of entropy calculations.

A major, and effective, objection to string theories is, that they cannot be tested against reality. Professor Penrose does not share that objection; this is natural, since he gives us here a cosmological theory which also cannot be tested against reality. As with string theory, we are confronted with a lot of mathematics which has no physical consequence.

A hope is expressed that there may be a method of coexistence. It might be found with experimental mechanisms or it might not be found. It might be found in ways not expected.
