🎞State-Space Compression, Coarse-Graining, and the Averaging of Life and Mind
Simon DeDeo
Abstract Renormalization is a principled coarse-graining of space-time. It shows us how the small-scale details of a system may become irrelevant when looking at larger scales and lower energies. Coarse-graining is also crucial, however, for biological and cultural systems that lack a natural spatial arrangement. I introduce the notion of coarse-graining and equivalence classes, and give a brief history of attempts to tame the problem of simplifying and "averaging" things as various as algorithms and languages. I then present state-space compression, a new framework for understanding the general problem. At the end, I present recent empirical results, in an animal social system, that show evidence for the coupling of scales: the reaction of coarse-grained facts about a system "downwards" to influence the microphysics.

On Tuesday, some local media outlets included Sing Tao Daily cited sources as saying the Hong Kong government was considering restricting access to Telegram. Privacy Commissioner for Personal Data Ada Chung told to the Legislative Council on Monday that government officials, police and lawmakers remain the targets of “doxxing” despite a privacy law amendment last year that criminalised the malicious disclosure of personal information. Telegram is a leading cloud-based instant messages platform. It became popular in recent years for its privacy, speed, voice and video quality, and other unmatched features over its main competitor Whatsapp. Today, we will address Telegram channels and how to use them for maximum benefit. Your posting frequency depends on the topic of your channel. If you have a news channel, it’s OK to publish new content every day (or even every hour). For other industries, stick with 2-3 large posts a week. With the administration mulling over limiting access to doxxing groups, a prominent Telegram doxxing group apparently went on a "revenge spree."
