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।

How Clean Air Warms the Earth

Today, we’re exploring a microscopic landscape completely invisible to the naked eye—a world of 'ghost' particles that control both our climate and our own biology.

I came across the 2013 paper "The thermodynamics of direct air capture of carbon dioxide" by Klaus Lackner https://www.sciencedirect.com/science/article/abs/pii/S0360544212006901. It describes the theoretical minimum energy needed to separate CO2 from the surrounding air. One interesting takeaway is that it is energetically less costly to "skim" CO2 from the air (capture a small fraction of the CO2 in the air and then moving on to more fresh air). This means that direct air capture is not necessarily much more energy intensive than scrubbing exhaust from smokestacks. In the scrubbing use case, you want to get all the CO2 before adding the exhaust to the atmosphere.

Basics of Numerical Weather Prediction (NWP):

1. THE HORIZONTAL MOMENTUM EQUATION:
\[
\frac{d\mathbf{V}}{dt} + f\hat{k} \times \mathbf{V} = -\nabla \phi + \frac{\sigma}{p_s} \frac{\partial \phi}{\partial \sigma} \nabla p_s + \mathbf{F}
\]

2. THE CONTINUITY EQUATION:
\[
\frac{\partial p_s}{\partial t} + \nabla \cdot (p_s \mathbf{V}) + \frac{\partial}{\partial \sigma}(p_s \dot{\sigma}) = 0
\]

3. THE THERMODYNAMIC ENERGY EQUATION:
\[
\frac{1}{R} \frac{d}{dt} \left[ \sigma \frac{\partial \phi}{\partial \sigma} \right] + \frac{RT}{C_p p} \left[ p_s \dot{\sigma} + \sigma\dot{p_s} \right] = -Q
\]

4. HYDROSTATIC EQUATION:
\[
\frac{\partial \phi}{\partial \sigma} = -\frac{RT_v}{\sigma}
\]

5. SURFACE PRESSURE TENDENCY EQUATION:
\[\displaystyle
\frac{\partial p_s}{\partial t} = -\int_{0}^{1} \nabla\cdot (p_s \mathbf{V}) \, d\sigma
\]

6. MOISTURE EQUATION:
\[\displaystyle
\frac{\partial}{\partial t} (p_s q) + \nabla\cdot (p_s q \mathbf{V}) + \frac{\partial}{\partial \sigma} (p_s q \dot{\sigma}) = p_s S
\]

The six primary unknowns are: \(\mathbf{V}\) (horizontal wind velocity), \(p_s\) (surface pressure), \(T\) (temperature), \(q\) (specific humidity or moisture), \(\phi\) (geopotential), and \(\dot{\sigma}\) (sigma velocity or vertical velocity in \(\sigma\)-coordinates).

This week, let’s spotlight an excellent foundational Nordita lecture series by Dr. Ivan Khaymovich, available in #OpenAccess on Enabla. This advanced Master-level course offers a modern introduction to the principles of thermalization, ergodicity, and their breakdown in both classical and quantum systems. It's a timely and valuable resource for students and researchers working on nonequilibrium dynamics, chaos, information thermodynamics, and localization phenomena.

💡 Even better: Ivan is on Enabla and happy to help clarify any questions you may have about the lectures. Don’t miss this unique opportunity to deepen your understanding of one of the most active frontiers in theoretical physics; watch and discuss the course with its author and others at https://enabla.com/set/182
