منظور ما از پدیدارگی یا emergence در سیستمهای پیچیده چیه؟!
انگاره پیچیدگی عینک جدیدی برای مطالعه طبیعت به ما میدهد. سیستمهای پیچیده از تعداد زیادی اجزا تشکیل شدهاند که در مقیاس ریز، اجزایشان برهمکنشهای موضعی دارند و در مقیاس درشت، رفتارهای «پدیداره» از خود نشان میدهند که شبیه به رفتار اجزای آنها در مقیاس ریز نیست. پدیدارگی در مورد این جور پدیدههاست.
این ویدیو دعوتی است برای خواندن این مقاله مروری کوتاه:
What is emergence, after all?

74% of MPI postdocs are international (immigrants).
Only about 25% of those international postdocs are certain they want to stay in Germany after their postdoc ends. Many cite family reasons, better opportunities abroad, or language barriers as factors.

🎞 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.
