@LaloMedecigoMR WOW nunca nos contestaron ni por aquí ni por face ni por las páginas oficiales @LaloMedecigoMR ni modo

@LaloMedecigoMR Quisiera presentarle una propuesta para uná área deportiva en nuestro municipio. En una zona como lo es los #FracccionamientosLasReynas, en la cual no contamos con áreas deportivas cercanas y que son de gran importancia para el municipio

@henrikl1967 @LensScientific I'll share a unifying proposal with you. However, the time flow is not considered the same. Fourth Law of thermodinamyc researchgate.net/publication/39…

Time is We propose the Fourth Law of Thermodynamics, completing the classical framework by explaining what the first three laws leave unaddressed: why physical processes require time. The Fourth Law — the Latency Law — states that no state change in a connected system can occur instantaneously; observed time (dt) represents the processing latency required for tension regulation. This transforms time from a mysterious external dimension into an emergent system property arising from finite information processing in physical arrays. We derive the Fourth Law from the Theory of Cosmic Architecture (TOCA), demonstrate its necessity for completing thermodynamics, and show it unifies the previous three laws while providing the physical foundation for consciousness, computation, and causality. Time is not a backdrop against which physics occurs — it is the signature of physics occurring. doi.org/10.5281/zenodo…

Albert Einstein, in 1905, revealed something that shook the foundation of knowledge. “Time is not absolute.” Imagine standing there, knowing you have just rewritten the way humanity understands reality.

@PhysInHistory But don't conclude that entropy decreases as things in the system cool. As energy shifts, the parts that cool do so at a higher temp (larger denominator) than the temp of the parts that heat up, so they lose less entropy than the cooler parts gain.

Erwin Schrödinger on entropy ✍️ What is entropy? ...a measurable physical quantity just like the length ...temperature ...the heat of fusion ...or the specific heat of any given substance. At ...absolute zero ...the entropy of any substance is zero. When you bring the substance into any other state by slow, reversible little steps ...the entropy increases by an amount computed by dividing every little portion of heat you had to supply ...by the absolute temperature at which it was supplied ...and by summing up all these small contributions. -- as mentioned in his book "What is Life?"

@PhysInHistory "measure of disorder". the higher the entropy, the more random and disordered the system is

@LjiljanaGruden2 @PhysInHistory Check this researchgate.net/publication/39…

@PhysInHistory Erwin Schrödinger's explanation of entropy in What is Life? is celebrated for its clarity because it connects entropy to familiar physical quantities, grounds it in fundamental thermodynamic laws, & uses math that bridges macroscopic processes and microscopic behavior.

@PhysInHistory Schrödinger beautifully simplifies entropy—a measurable quantity rising with every bit of heat added, like nature's bookkeeper of disorder. A fascinating glimpse into the laws of life!

@PhysInHistory Sadi Carnot, through his analysis of steam engines, discovered a simple linear mathematical relationship between heat energy, work energy, temperature of the heat energy and entropy... chem.tamu.edu/class/majors/c…

@PhysInHistory Used in information theory. Entropy measures uncertainty in data. Higher entropy means more unpredictability; lower entropy means more order. It’s the foundation of data compression, cryptography, and efficient communication systems.

What Odum called transformity can be written as: A/E = (T0·S_gen)/(U − T0·S_gen). Same idea, different language. Emergy counts the history. The 4th Law provides the physical foundation. modynamics

Two ecosystems can receive the same solar energy and still have very different costs. Why? Because usable energy E shrinks as entropy is generated: dE = dU − T0·dS_gen. That’s Odum’s hierarchy, written in thermodynamics. researchgate.net/publication/39…

Energy is conserved, but its quality is not. Odum showed this ecologically. The 4th Law shows it physically: dU = dE + dA, with dA = T0·dS_gen. More complexity → more degraded energy → less usable energy.

@gilbertoromboli Same 100 kW of rejected heat, two design effects: Raising radiator temperature: Area drops sharply (Stefan–Boltzmann, T⁴) Anergy drops as well (4th Law: Q·T₀/T) Smaller hardware and less energy degradation at the same time. Efficiency is about energy quality, not just heat.

Is it possible to reduce the size of a radiator by increasing the temperature of the fluid that reaches the radiator? Yes, and this example shows how, for the same 100 kW, it is possible to reduce the radiator size by up to 80%. The key lies in the fourth power dependency of the Stefan-Boltzmann law. Let's look at the calculations: Temperature ratio: T₂ / T₁ = 450 / 300 = 1.5 But radiated power depends on T⁴, so the required area scales inversely: A ∝ 1 / T⁴ Therefore: A₁ / A₂ = (T₂ / T₁)⁴ = (1.5)⁴ = 5.0625 This matches exactly the ratio you can see in the example: A₃₀₀ / A₄₅₀ = 256.16 / 50.60 ≈ 5.06 In simple terms: By increasing the temperature by 50% (×1.5) → the required radiator surface area is reduced by approximately 80% (÷5.06).

@gilbertoromboli Radiator area ↓ ~80%, exergy destruction ↓ ~33%. Manuscript available for journal consideration. researchgate.net/publication/39…

@gilbertoromboli Exergy of heat: Ė = Q̇ (1 − T₀ / T) At 300 K (T₀ = 300 K): Ė = 0 kW → all heat is anergy At 450 K: Ė = 100 (1 − 300/450) ≈ 33 kW Higher temperature = higher energy quality. Smaller radiator, less exergy destroyed.
