SLOW DECAY. “It has also been conjectured that information becomes highly scrambled. We show that all the above properties are shared by other well-defined systems with enhanced memory storage capacity that seemingly have nothing to do with black holes.” https://www.d-itp.nl/shared-content/events/events/scientific/00/2018-okt-18-georgi-dvali-iop-colloquium.html?cb View in LinkedIn

GENERALIZABLE. “These systems can be described as quantum fields or neural networks. This striking similarity suggest that there exists an underlying universality in enhancement of information storage capacity that extends across the disciplines. All the phenomena have counterparts in the classical limit, with the role of quantum scrambling taken up by a classical chaos.” https://www.d-itp.nl/shared-content/events/events/scientific/00/2018-okt-18-georgi-dvali-iop-colloquium.html?cb View in LinkedIn

IMAGINE THE UNIMAGINABLE. “Could there be worlds where contradictions are normal parts of existence-worlds where contradictious are not contradictions? Is Number Theory the Same In All Conceivable Worlds? https://lnkd.in/dmfn9qW View in LinkedIn

Barcelona has some of the most exquisite old stucco work of any city, done by an army of highly skilled artesans, but the skill has almost entirely vanished and few know how to do this today. View in LinkedIn

BLACK HOLES AND ENTROPY is the theme for the next section of posts. The introductory posts are from Jacob Bekenstein’s prescient Princeton PhD thesis in 1972. https://lnkd.in/d_-_tga View in LinkedIn

COMMON IRREVERSIBILITY. “There are a number of similarities between black-hole physics and thermodynamics. Most striking is the similarity in the behaviors of black-hole area and of entropy: Both quantities tend to increase irreversibly. In this paper we make this similarity the basis of a thermodynamic approach to black-hole physics. https://lnkd.in/d_-_tga View in LinkedIn

THE HIDDEN INSIDE. “We show that it is natural to introduce the concept of black-hole entropy as the measure of information about a black-hole interior which is inaccessible to an exterior observer.” https://lnkd.in/d_-_tga View in LinkedIn

THE EQUATION. “Considerations of simplicity and consistency, and dimensional arguments indicate that the black-hole entropy is equal to the ratio of the black-hole area to the square of the Planck length times a dimensionless constant of order unity.” https://lnkd.in/d_-_tga View in LinkedIn

BLACK HOLE ENTROPY. “A different approach making use of the specific properties of Kerr black holes and of concepts from information theory leads to the same conclusion, and suggests a definite value for the constant.” https://lnkd.in/d_-_tga View in LinkedIn

THE RABBIT HOLE. “The physical content of the concept of black-hole entropy derives from the following generalized version of the second law: When common entropy goes down a black hole, the common entropy in the black-hole exterior plus the black-hole entropy never decreases.” https://lnkd.in/d_-_tga View in LinkedIn
