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

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

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

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

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

END OF PAPER. This concludes this difficult and extraordinary paper by Gia Dvali of the Max Planck Institute in Germany. It illustrates the type of extreme thinking that is possible when physicists turn their minds to biology, and the novelty of their whole approach. It will be a great day when more physicists think about biological complexity with their very special way of analyzing reality. https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=GdPRXs_tGLEAAAAA%3Ag-pxPMtkcleTYDUNK3mYGfpEzKRyc2LqQknTgFFB7dkYFDL8rDe2s0f4_0Q0oKjXD4_AEgFPGWolVTQ View in LinkedIn
