🔖 Meaning = Information + Evolution by Carlo Rovelli

Bookmarked Meaning = Information + Evolution (arxiv.org)
Notions like meaning, signal, intentionality, are difficult to relate to a physical word. I study a purely physical definition of "meaningful information", from which these notions can be derived. It is inspired by a model recently illustrated by Kolchinsky and Wolpert, and improves on Dretske classic work on the relation between knowledge and information. I discuss what makes a physical process into a "signal".

🔖 Irreversibility and Heat Generation in the Computing Process by R. Landauer

Bookmarked Irreversibility and Heat Generation in the Computing Process (ieeexplore.ieee.org)
It is argued that computing machines inevitably involve devices which perform logical functions that do not have a single-valued inverse. This logical irreversibility is associated with physical irreversibility and requires a minimal heat generation, per machine cycle, typically of the order of kT for each irreversible function. This dissipation serves the purpose of standardizing signals and making them independent of their exact logical history. Two simple, but representative, models of bistable devices are subjected to a more detailed analysis of switching kinetics to yield the relationship between speed and energy dissipation, and to estimate the effects of errors induced by thermal fluctuations.
A classical paper in the history of entropy.

🔖 Why Boltzmann Brains Are Bad by Sean M. Carroll

Bookmarked Why Boltzmann Brains Are Bad (arxiv.org)
Some modern cosmological models predict the appearance of Boltzmann Brains: observers who randomly fluctuate out of a thermal bath rather than naturally evolving from a low-entropy Big Bang. A theory in which most observers are of the Boltzmann Brain type is generally thought to be unacceptable, although opinions differ. I argue that such theories are indeed unacceptable: the real problem is with fluctuations into observers who are locally identical to ordinary observers, and their existence cannot be swept under the rug by a choice of probability distributions over observers. The issue is not that the existence of such observers is ruled out by data, but that the theories that predict them are cognitively unstable: they cannot simultaneously be true and justifiably believed.

📖 Read pages 86 – 115 of 430 of Dealing with China by Henry M. Paulson, Jr.

Cleaning the Stables in Guangdong was interesting, but could have had some more details and data (or a better case study, given its potential value). Alas it was just a quick overview of two years of work, possibly because editors thought it might be overly boring, but really who is going to read this book, but people who want these types of details.

I find at times in the book, he becomes overly gracious and almost too complimentary which I take to mean that he is still ingratiating himself to colleagues and potential future relations.

The chapter on School for Success could itself have been a better and more in-depth case study, but was a short historical outline.

There are some occasional interesting tidbits hidden throughout the chapters which are generally illuminating, but I wish there were more useful insider tidbits of true value. So far I’m not reading anything much more valuable than could be found in overview newspaper articles covering some of the same topics.

What a lovely little volume, though a bit sappier in the end than I would have liked or expected given the realities of the earlier portions.

I’ve an interesting thesis about what the book is really about. Details to come…

Read Don’t Cancel the Academy Awards Over Trump. Oscar Nominees, Try This Instead. (Slate Magazine)
With the news that that the latest disaster in Donald Trump’s Lizard Brain Jamboree will bar Oscar nominee Asghar Farhadi from attending the Academy Awards (and Farhadi’s later decision to skip them whether he is allowed to come or not), the film community has been scrambling to find an effective response.
