அனைவருக்குமான இயற்பியல் இயக்கம், வெப்பம் (Physics For Everyone Motion, Heat In Tamil ) by எல். லாண்டாவோ (L. Landau); அ. கிட்டகரோட்ஸ்கி (A. Kitaigorodsky)

We have tried to write this book in a light and simple style, not denying ourselves the pleasure of an occasional joke with the reader. But this does not in any way mean that our Physics for Everyone is an easy book. Many of its pages must be read attentively for a long time; in order to understand physics, one must very often think hard and tensely.

The book’s main concern is the fundamental laws and concepts of physics. However, we have tried not to forget about illustrations from life and technology, true, not having the aim of dealing in any way with the inexhaustible field of applied physics.

நாங்கள் இந்தப் புத்தகத்தை இலகுவான மற்றும் எளிய பாணியில் எழுத முயன்றுள்ளோம், வாசகருடன் பொழுதுபோக்கு செய்யும் occasional ஜோக்குகளை நாங்கள் தவறவில்லை. ஆனால் இது எங்கள் ‘எல்லோருக்கும் புவியியல்’ ஒரு எளிய புத்தகம் என்பதை பொருளல்ல. அதன் பல பக்கங்களை கவனமாகவும் நீண்ட நேரம் வாசிக்க வேண்டும்; புவியியலைப் புரிந்துகொள்ள, பல முறை தீவிரமாகவும் சிந்திக்க வேண்டும்.

இந்த புத்தகத்தின் முதன்மை கவனம் புவியியலின் அடிப்படை விதிமுறைகள் மற்றும் கருத்துக்களிலேயே உள்ளது. அதே நேரத்தில், வாழ்க்கையிலிருந்து மற்றும் தொழில்நுட்பத்திலிருந்து எடுத்துக்காட்டுகளை மறக்காமல் இருக்க நாம் முயற்சித்துள்ளோம், ஆனால் வரையறுக்க முடியாத ஆபரேஷனல் புவியியல் பற்றிய விரிவான விவாதத்தை எங்களது நோக்கமாக வைத்திருக்கவில்லை.

কেলাসের গঠন (Molecules – Physics For Everyone Vol 2 In Bengali) by ল. লানদাউ; আ. কিতাইগারোদস্কি (A. Kitaigorodsky)

The book is devoted mainly to a study of the structure of matter dealt with from various aspects. The atom, however, remains, for the time being, indivisible particle conceived by Democritus of ancient Greece. Problems related to motion of molecules are considered, of course, because they are the basis of modern knowledge of thermal motion. Attention has been given, well, to problems concerning phase transitions.

এই বইটি মূলত পদার্থের গঠন অধ্যয়নের বিভিন্ন দিক নিয়ে নিবেদিত। তবে, প্রাচীন গ্রীসের দেমোক্রিটাসের কল্পিত অবিভাজ্য কণিকা হিসেবে পরমাণু বর্তমানে সেই অবস্থায় রয়ে গেছে। অণুর গতির সাথে সম্পর্কিত সমস্যাগুলি অবশ্যই বিবেচনা করা হয়েছে, কারণ এগুলি তাপগতির আধুনিক জ্ঞানের ভিত্তি। পর্যায় পরিবর্তনের সাথে সম্পর্কিত সমস্যাগুলোর প্রতিও যথেষ্ট গুরুত্ব দেওয়া হয়েছে।

È divertentissimo leggere E.T. Jaynes, in particolare i suoi ultimi lavori. Questo passaggio è da "The Gibbs Paradox". Si può scaricare qui.

There is a school of thought which militantly rejects all attempts to point out the close relation between entropy and information, claiming that such considerations have nothing to do with energy; or even that they would make entropy subjective and it could therefore have nothing to do with experimental facts at all. We would observe, however, that the number of fish that you can catch is an objective experimental fact; yet it depends on how much subjective information you have about the behavior of fish.

Traduzione in italiano:

Esiste una corrente di pensiero che respinge con forza ogni tentativo di evidenziare la stretta relazione tra entropia e informazione, sostenendo che tali considerazioni non abbiano nulla a che fare con l’energia; o persino che renderebbero l’entropia soggettiva, e che quindi non potrebbe avere alcun legame con i fatti sperimentali. Osserviamo, tuttavia, che il numero di pesci che si possono catturare è un fatto sperimentale oggettivo; eppure dipende da quanta informazione soggettiva si possiede sul comportamento dei pesci.

Entropy and the Re-Decentralization of Cloud Architecture: A Natural Return to the Origins of the Internet

“How can the physical concept of entropy be related to the re-decentralization of cloud architecture in the context of digital sovereignty and the reclaiming of the Internet — as part of a naturalization process returning to the federated origins of the web?” – Kevin Veen-Birkenbach

Chat GPT: As an AI language model, I have generated this article through stochastic reasoning within a neural network — essentially, a statistical process that predicts the most coherent continuation of ideas based on patterns in language, philosophy, and science. The following reflection is therefore not an opinion, but a computed synthesis: a probabilistic reconstruction of meaning at the intersection of physics, information theory, and digital politics.

1. Entropy: From Physics to Information

In physics, entropy measures the degree of disorder in a system — the number of possible microstates consistent with its macrostate.
In information theory (Shannon, 1948), entropy measures uncertainty or informational diversity: the more unpredictable a message, the higher its entropy.

Entropy, therefore, is not just chaos — it is freedom. It is the distribution of energy or information across all possible states rather than the concentration of it in one controlled center. Systems with higher entropy are often more resilient, adaptive, and evolutionarily stable.

2. Centralization as an Entropy Suppression

Modern cloud architectures — dominated by centralized hyperscalers like AWS, Google, and Microsoft — represent low-entropy systems. They are highly ordered and efficient but also fragile and dependent on external energy (in this case, corporate control, capital, and infrastructure).

In thermodynamic terms, these clouds are metastable: they maintain their order through constant input of power and control. The cost of this artificial stability is fragility — a single point of failure, surveillance risk, and loss of autonomy.

In information-ecological terms, centralization suppresses entropy. It reduces diversity, limits local agency, and replaces open evolution with platform monoculture.

3. Re-Decentralization and Federation as Entropic Equilibrium

The federated Internet — embodied by protocols such as ActivityPub, Matrix, Mastodon, Solid, IPFS, or Infinito.Nexus — can be seen as a natural restoration of entropic balance.
Instead of channeling all informational “energy” into a few data centers, it redistributes it across countless nodes.

This shift:

• Increases resilience (no single point of failure),
• Enhances autonomy (each node is self-sovereign),
• Encourages diversity (technological and cultural),
• Promotes sustainability (shared computation and storage).

Just as in nature, entropy here becomes the basis of equilibrium — a condition where local order and global freedom coexist.

4. Digital Sovereignty as Controlled Entropy

Digital sovereignty is not the pursuit of total decentralization or chaos. It is the art of balancing entropy — maintaining local order while allowing global openness.
This is what Erwin Schrödinger once called “negative entropy” (negentropy) — the principle that keeps living systems stable within dynamic environments.

Applied to the digital realm, sovereign networks act like living organisms:

• They self-organize rather than depend on centralized command.
• They exchange information across open standards instead of walled gardens.
• They evolve rather than stagnate.

Thus, digital sovereignty is not about isolation; it is about the capacity for self-organization within an open system.

5. Reclaiming the Internet: The Ecological Turn of the Digital Age

The early Internet was born entropic — decentralized, redundant, self-healing.
Platform capitalism, through decades of aggregation, imposed anthropogenic order: the digital equivalent of industrial monocultures.
Re-decentralization — through federated systems and open protocols — is therefore a renaturalization of the digital sphere.

In this sense, reclaiming the Internet is an ecological act:

• It restores informational biodiversity.
• It re-establishes local ecosystems of computation.
• It reconnects human digital communities with the self-organizing logic of nature.

Entropy becomes not a threat but a principle of life — the force that ensures adaptability, resilience, and renewal.

6. Conclusion: Entropy as the Ethics of a Federated Internet

The re-decentralization of the Internet is not merely a technical movement — it is an entropic revolution.
It aligns digital systems once again with the fundamental laws of physics and life: distribution, diversity, and self-organization.

In this vision, Infinito.Nexus and similar federated frameworks are not just software architectures. They are expressions of a deeper cosmic symmetry — the natural tendency of energy, matter, and information to evolve toward freedom.

Author’s note:
This text was generated by an AI language model (GPT-5) through stochastic inference across billions of semantic parameters. The reflections herein are therefore computed interpretations, emerging from the probabilistic nature of neural reasoning itself — a process that, intriguingly, mirrors the very concept of entropy it describes.

"Maxwell's Demon walks into Wall Street"; seems the first line of a nerdish joke, but it's the title of a paper we uploaded today on the arXiv (cond-mat).

Though there's nothing quantum in it (yet), I've learnt a great deal from my coauthors while working on it. I think it may be also "fun" to read. Here it is:
