The Steel Greenhouse in an Ambient-Temperature Environment

Climate of Sophistry

The “steel greenhouse” concept for demonstrating the radiative greenhouse effect has been debunked many times on this blog (the least reason of which its advocates attempt to conserve temperature instead of energy!), but the solution for it sitting in an ambient-temperature environment has never been demonstrated. We will do that now here and will present the maths for both of the scenarios where for a) the ambient-temperature is zero Kelvin, and b) the ambient-temperature is greater than zero.

Willis Eschenbach’s diagram of his steel greenhouse, as advocated by Anthony Watts and Roy Spencer and others.

Advocates of the steel greenhouse think that temperature is a conserved quantity, i.e., that temperatures add together. Their diagram above shows a “core” producing 235 W/m2out of its surface area, and they think that this is conserved by the shell emitting at the same temperature at 235 W/m2 over a larger surface…

The Multiverse Can Only Kill Physics by Becoming Physics

4 gravitons

I’m not a fan of the multiverse. I think it’s over-hyped, way beyond its current scientific support.

But I don’t think it’s going to kill physics.

By “the multiverse” I’m referring to a group of related ideas. There’s the idea that we live in a vast, varied universe, with different physical laws in different regions. Relatedly, there’s the idea that the properties of our region aren’t typical of the universe as a whole, just typical of places where life can exist. It may be that in most of the universe the cosmological constant is enormous, but if life can only exist in places where it is tiny then a tiny cosmological constant is what we’ll see. That sort of logic is called anthropic reasoning. If it seems strange, think about a smaller scale: there are many planets in the universe, but only a small number of them…

Breath is viewed as observation – By Akshay Kumar Das

“Listening to your breath is viewed as observation” tuning in to the trilling of feathered creatures is a reflection.

In this, I mean Breathing a normal phenomenon is much more important, oxygen you breath with this polluted air with an unhealthy mind is not fresh breathing. If one breath good air, he is equally honored to be in heaven.

For whatever length of time that these exercises and including the exercises which happen normally are free from some other diversion to the mind-body, it’s the genuine reflection.

Understanding depth of Einstein’s Field Equations – By Akshay Kumar

I never attempted these equations until I make my own particular scientific ways to deal with the level of numerical ability of science required for this, I used to think like this when I was the student. I recommend readers of my blog to read Einstein’s field equations, but before understanding them, know that the field conditions need higher arithmetic… folks once consider the photoelectric impact, that was most prominent disclosure which Einstein got Nobel prize, but now school children discover that and they comprehend the fundamentals. Same way the field condition needs fundamentals (those we don’t think about in school) They are in harmony with the complex understanding of the universe.

learning Einstein’s certain speculations give more creative energy to the mind, I myself-got comprehend when I endeavored to find out about the Einstein exceptional hypothesis of relativity.

The Einstein field conditions (EFE) or Einstein’s conditions are an arrangement of 10 conditions in Albert Einstein’s general hypothesis of relativity which depict the essential collaboration of attraction because of spacetime being bent by issue and Relativity. In the first place distributed by Einstein in 1915 as a tensor condition, the EFE compare nearby spacetime ebb and flow (communicated by the Einstein tensor) with the neighborhood Relativity and force inside that spacetime (communicated by the stress– relativity tensor).

Like how electromagnetic fields are resolved to utilize charges and streams by means of Maxwell’s conditions, the EFE are utilized to decide the spacetime geometry coming about because of the nearness of mass-Relativity and direct force, that is, they decide the metric tensor of spacetime for a given course of action of stress– relativity in the spacetime. The connection between the metric tensor and the Einstein tensor permits the EFE to be composed as an arrangement of non-straight fractional differential conditions when utilized as a part of along these lines. The arrangements of the EFE are the segments of the metric tensor. The inertial directions of particles and radiation (geodesics) in the subsequent geometry are then ascertained utilizing the geodesic equation. As well as obeying neighborhood Relativity force protection, the EFE lessen to Newton’s law of attractive energy where the gravitational field is powerless and speeds are substantially less than the speed of light. Exact answers for the EFE must be found under rearranging presumptions, for example, symmetry. Extraordinary classes of correct arrangements are frequently examined as they show numerous gravitational marvels, for example, turning dark gaps and the expanding universe. Assist rearrangements is accomplished by approximating the genuine spacetime as level spacetime with a little deviation, prompting the linearized EFE. These conditions are utilized to ponder wonders,

for example, gravitational waves. Similar to how electromagnetic fields are resolved utilizing charges and streams through Maxwell’s conditions, the EFE are utilized to decide the spacetime geometry coming about because of the nearness of mass-Relativity and straight force, that is, they decide the metric tensor of spacetime for a given course of action of stress– Relativity in the spacetime. The connection between the metric tensor and the Einstein tensor permits the EFE to be composed as an arrangement of non-straight incomplete differential conditions when utilized as a part of along these lines. The arrangements of the EFE are the segments of the metric tensor. The inertial directions of particles and radiation (geodesics) in the subsequent geometry are then computed utilizing the geodesic condition.

And in addition, obeying neighborhood Relativity force preservation, the EFE lessen to Newton’s law of attractive energy where the gravitational field is frail and speeds are considerably less than the speed of light.

Exact answers for the EFE must be found under streamlining presumptions, for example, symmetry. Uncommon classes of correct arrangements are frequently contemplated as they demonstrate numerous gravitational wonders, for example, pivoting dark gaps and the expanding universe. Promote disentanglement is accomplished by approximating the genuine spacetime as level spacetime with a little deviation, prompting the linearized EFE. These conditions are utilized to think about marvels, for example, gravitational waves.

Gravitational “Anomalies” Caused by Shapiro Delayed Traveling Energy Quanta Around Galactic and Cosmic Scale Structures

ENERGY FELT HYPOTHESIS

Abstract.  In 1964, Irwin Shapiro pointed out that electromagnetic waves traveling near a gravitational well of a star were delayed due to relativistic Gravitational Time Dilation (GTD). This paper proposes that traveling energy quanta (mainly vacuum energy and gravitational waves, as well as neutrinos, electromagnetic waves, cosmic rays, stellar winds, and all other kinds of waves and relativistic particles yet to be discovered) accumulate in a Density Wave like mechanism around the galactic and cosmic scale structures because of Shapiro Delay. Ultimately, the accumulative effect is a substantial increase in energy density when seen from frames of reference far from the regions where it occurs. The higher energy density is imperceptible for an observer within its own frame of reference since the proposed mechanism nature is relativistic. The higher concentration of travelling energy quanta around galaxies and galaxy clusters is creating extra gravitational distortion in spacetime with its mass equivalent.Ramen EquationThe…

How to live longer? Physics perspective of this biological heart.[the analogy with machine & heart]

In this massive place of living systems, Homo sapiens emerged into a pioneer in technological revolutions since from early ages. It’s the technological optimism. We are at this age where we are into bionics, artificial intelligence, much more. due to the much more complex understanding of this nature made us to clearly understand the neutrons to neurons in our brain, as we are also running towards other planets, happen to see extra-planetarily voyages in future. To know the universe better.

One of the keen thought emerged within me, it’s how long we enjoy these things? can we break that barrier of death and diseases in future? Can the man win himself in preventing him from ageing? Yes, why can’t we live forever? These are somethings which are challenging questions which are running through my mind. But in reality, I’m not saying the man can become immortal. But at least live longer with healthful life.

Let me go further, what is aging actually? is that only changes in physical appearance, changes in biological structure? Truly, Ageing is the process of growing old chronologically, it’s the normal process occurs to all living bodies. We can say a functional state of the living organism changes gradually when our age increases. Even the organs and organ systems show different rates of decline. The cell dies, the effectiveness of our metabolism rate decreases [ I will share some posts about the thermodynamics of human metabolism in my next post], weakening of nerves system, finally we become like neonate, I wonder Indian knew this as Kala Chakra. Human Cycle of birth and death. Growing old and person becoming the man of wrinkles in his bodies, a skin becomes as soft as babies’ skin, I visit old age houses they literally become small babies, just to add the point, please take care of elderly senior citizens, they are like small kids.

Well, In this article, I choose the Heart and its physics of working phenomena, not exactly a biological point of view. But rather some light on analogy with a machine.

I heard that heart grows larger slightly with age, But it’s similar kind of analogy with machines, where we call durability of machines. We care them we maintain them for longer usage. soon scientists finding a way to increase the average lifespan. man is finding solutions to heart diseases. But this beautiful heart is complex & interesting we sometimes relate heart to our emotions. love, livelihood. Truly who has got good heart will live longer.

Mechanical Pumps VS Heart pumps

Yes, you read it right, I think the heart is a biological pump in a human body. a bit similar to a mechanical pump. But it’s not a single pump it’s two pumps in one organ. The heart pumps the blood, like Pump transfer water or fluids. But it’s working is not same as our mechanical pump.

Heart contracts and relaxes, the heart actually squeezes itself. So, what makes the heart squeeze? It’s the “shock”. The heart is a muscle and like every muscle is going to contract when a shock is produced. they contract and forces the blood downwards.

If anyone wants to know how the shock is produced in living creatures, physics point of view here it comes, it’s Bioelectric/bioelectromagnetic.

I wish to show an illustration which is about 250 years old, Luigi Galvani an Italian physicist first demonstrates the twitch or contacts/expand of frog legs. When two metallic arcs are brought near the frog legs they twitch. This is something like “life force”. Like Actuating phenomena in mechanical systems and even similarly modern electrical actuating and robotic systems. Galvani concluded that electricity is generated in the animal and that with this special metal arc this ‘life-force’ can be discharged, which makes the leg twitch.

 

as

Illustration of Galvani’s twitching frog leg, when touching it with an arc made of zinc and copper.

 

 Hope it was the agreeable answer for how really electric current generated in muscles, but let me tell you it’s much more complex in heart muscles than this frog legs twitch.

What is that complex thing?

There are complex things happening in living human heart. It’s nothing but action potential occurs when the membrane potential of an axon location rapidly rises and fall back. This depolarizing causes other locations to work similarly. We cannot go further without saying about the sinoatrial node. These have some sort of cells which produce electric impulse.sinoatrial node and it’s working can be analyzed with modern computational techniques. cardiac graphical representations, thanks to the modern world of engineering, especially Bio-medical engineering are focused and developing largely.

What are these above sentences saying about longevity? 

The heart is going to increase its size slightly with the ageing. Maximal oxygen consumption during exercise declines in men by 10 percent with each decade of adult life and in women by about 7.5 percent. These data are from the data by book written by Dr. HK Bakhru.

How complex things happening but we less consider this personally, people smoke, follow unhealthy things and make this beautiful creation of life to end with disease… and finally deaths. Whatever this technological revolution may come but unless man follows the nature’s rule, survival of fittest. Evolution of intellectual values of human is important but a big neglect may make him fly away from this earth.

But let me come back to the actual topic of longevity, now we come to know that heart requires electric current but anyway they generated and functionally not requires our support, but they require healthy habits to work properly so this system may deploy gradually when aging continues. So, it’s pretty similar to our day to day machines. Improper maintenance may lead to failure of the machine. For longer life maintain your heart with proper exercise. Follow many good habits to increase the health of the heart, we have plenty of articles on fitness read them. I recommend to concern periodic checkups will help, just our machines servicing. Yes, finally I end this article with a small analogy of heart and machine.

Please do follow some things here below to make a healthy heart.

  1. Maintain a healthy weight.
  2. Eat well-suited foods.
  3. Do yoga regularly, if possible mediations.
  4. Manage blood pressure, Control cholesterol level, how? sorry, I’m physics geek, ask Dietitian and ask your family doc. Well, just kidding.
  5. Stop smoking, please do it from the heart, for your heart. Also for others heart.
