  2. 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.

  3. 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।

  5. My Book “The Physics of Creation” Now on Sale on Creation Today

    My book “The Physics of Creation: The Creator’s Ultimate Design for Earthis now on sale on CreationToday.org. The PDF of the book can be downloaded for less than just $5. The book contains a lot of content that no other creation book presently has. Visit the site and support the Creation Today ministry by buying a copy.

    The following are excerpts from the Creation Today webpage.

    What if the laws of physics are evidence of a Creator rather than products of chance? In The Physics of Creation, physicist Dr. John Hartnett explores the universe through a biblical creation worldview, revealing how the laws of nature, the Earth, life, energy, the Flood, and even the future restoration of creation point to God’s purposeful design. Combining decades of scientific research with a deep study of Scripture, Hartnett presents a compelling case that the universe was created with intention, order, and purpose.

    Can modern physics help us better understand the biblical account of creation?

    In The Physics of Creation: The Creator’s Ultimate Design for Earth, renowned physicist and cosmologist Dr. John Hartnett takes readers on a fascinating journey through the physical universe from a biblical perspective. Drawing on more than fifty years of studying physics, mathematics, and Scripture, Hartnett argues that the laws governing the universe are not accidents of nature but evidence of an intelligent Creator.

    Beginning with the six days of creation described in Genesis, Hartnett examines the physics behind Earth’s formation, the heavens, life, thermodynamics, energy, Earth’s magnetic field, climate, geology, and the global Flood. He explores how the physical laws of the universe reveal remarkable design and purpose, while also addressing the effects of the Curse, the reality of decay, and God’s sustaining power over creation.

    If you want a different perspective of the history of Genesis creation to the present day get a copy.

  6. Cooling is rarely steady. Experiments show how heat transfer changes dynamically during rapid temperature drops.

    These transient effects matter for boiling regimes and could help refine models of vapor layer formation.

  7. The glider now has 12 pounds of lead shot and epoxy added to dead space in the very end of the tail boom.

    My initial estimate of volume indicated that I could add 8 - 10 pounds this way. I'm pleasantly surprised, and I didn't make a chocolate covered mess of things as I was pouring this goop into the tail.

    I need to add a few more pounds to the tail. Phase two of this project will use lead plate, bolted to the vertical fin spar. (I need to unroll the 1/4-inch plate first, then develop a template to cut the lead.)

    I could not add the epoxy/lead shot mix all at once because of the exothermic reaction of epoxy. When mixed epoxy is in a thick blob (instead of a thin layer), it generates enough heat to warm itself...which accelerates the chemical reaction...releasing more heat...further accelerating the reaction.... I have seen epoxy smoking hot because of this, so I added a bit, waited a half hour, checked temperature with an IR non-contact thermometer, added a bit more when it was clear that the exotherm was only very mild, etc. That took a while, but turned out well.

    I note that Roto Metals has a discount on some 1-inch lead plate. Get your fork lift ready. No free shipping!

  8. 🔬 Metasomatic Zonation as a Model of Groundwater Contamination

    One of the key theoretical bases in my research is the classical metasomatic zonation model (Korzhinskii, 1960s).

    I interpret the contamination halo formed by mine waters not as passive dispersion — but as an active metasomatic system, where aggressive fluids drive alteration and re-precipitation reactions within the carbonate aquifer.

    Highly mineralized mine waters create a complex interaction front.
    Thermodynamic modeling (based on well-monitoring data) allows identification of several geochemical zones partly analogous to Korzhinskii’s metasomatic sequence.

    📊 The image shows my preliminary zoning concept.

    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:

    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).

  13. How Cooling Towers Work

    Power plants (and other industrial settings) often need to cool water to control plant temperatures. This usually requires cooling towers like the iconic curved towers seen at nuclear power plants. Towers like these use little to no moving parts — instead relying cleverly on heat transfer, buoyancy, and thermodynamics — to move and cool massive amounts of water. Grady breaks them down in terms of operation, structural engineering, and fluid/thermal dynamics in this Practical Engineering video. Grady’s videos are always great, but I especially love how this one tackles a highly visible piece of infrastructure from multiple engineering perspectives.

  14. #STRATCOM (STRATospheric COMposition) was a long-term, multi-purpose program for integrated, correlated measurements of #stratospheric parameters related to composition, #thermodynamics, and radiative balance, primarily by the use of balloon-borne instruments.

    The program was run between 1968 and 1977.

    Below these lines, we can see the preparation, #balloon inflation, and #payload release of STRATCOM VIa. That mission was carried out at #Holloman AFB (NM) on September 23, 1975.

    Calling #Theil's #inequality measure an "#entropy" irritated #AmartyaSen. From Amartya Sen's "#OnEconomicInequality" (#OEI) I learned a lot about #InequalityMeasures. But entropy seems not do go down too well with him (1973) and his co-author #JamesEricFoster (1997): When describing the "interesting" "#TheilEntropy" (chapter 2.11), Sen sees a contradiction between entropy being a measure of "#disorder" in #thermodynamics and entropy being a measure for "#equality".
