The power of highest ecstasy – in understanding Universal love

Once I believed, you’re for me

You will always stay by my side till the sun & moon perish

To protect and care for me till we cherish

Love Ecstasy of each other will continue in heaven’s place if you not stop it (that is if you ask when it ends actually, in reality, heaven exists nowhere than in your place or heart) this is always fine to react to the mystic self-transcendence of love within our boundary line which has many relationships to tie it, but death is alone… we experience death alone. but keep it in mind love is not like death, if you experience the joy of highest form of love-ecstasy other people also experience himself. it is the universal love according to me.

till moon and stars will cherish in morning, more correctly to tell in the day we never see them, then this physical existence and love to this skeleton body which is covered with limited flesh are mysterious. Love to become immortal without disturbing the reality is what life. there is a fine condition called the universal love please try to grab.. and use it for rest of life.

My dear marshmallow Never mind – [ A poem ] By Akshay Kumar

I will see your thoughts as mine

My eyes will at no time fail to pursuit you

When you hide from me,

I am looking into your eyes

 

When I am beholding into your eyes

The love you show to your pet dog & tame kitten

At least show to me half, oh sorry at least

Unconditional love towards them, why not to me

 

Aren’t my eyes telling you I will never

leave you alone?

Is that so grim to know? I’m Romeo.

Do I need to tell you all these my dear marshmallow?

 

Once I believed, you’re for me

You will always stay by my side till the sun & moon perish

To protect and care for me till we cherish

Love Ecstasy of each other will continue in heaven

 

But never mind when I will never

Turn to your words, never mind you will

Stuck with a hard time of missing me

Never mind for prodigious feeling of loneliness surrounds you

If you mind about it, write back a poem. Hee Hee !!!

A review on the analysis and application of RS-25 cryogenic engine used in NASA’s typical space missions – Astrophysics

Abstract

The cryogenic propulsion technology consists of Liquid Hydrogen (-253°C) and Liquid Oxygen (-183°C). The Newton’s third law of motion is used as a basic principle. This is the only engine that gives 100% efficiency and without any greenhouse gas, vapors emissions. This engine gives a trust of 15000 lb. This thrust can be increased to a greater extent if a proper research is carried on this technology.

When these fuels are mixed at their cryogenic temperatures they give out huge energy which can be utilized. Especially liquid hydrogen (LH2) and liquid oxygen (LO2) cryogenic propellants dramatically increased NASA’s and ISRO’s ability to explore the solar system due to their superior specific impulse capability. These cryogenic propellants can be very difficult to manage also store, cryogenic engines are advantageous over traditional hypergolic propulsion systems and are therefore enabled for many planetary science missions.

A beautiful engine namely, RS-25 took its birth in 1960, the engine produces a specific impulse which is higher in a vacuum, and the RS-25 operates at temperatures ranging from 253 °C to 3300 °C.

For RS-25, regenerative cooling is used for nozzle and MCC. The use of advanced insulation and low thermal conductivity support structures will allow for the long-term storage and use of cryogenic propellants for solar system exploration and hence allows NASA to deliver more payloads in comparison with the present generation of advancements. Targets of interest launch on smaller and less expensive launch vehicles, or both.

Also, the resulting elastoplastic deformation in the combustion chamber at cyclic thermal and mechanical loading is being analyzed and a solution strategy has been developed. This is applied to the prediction of the heat transfer and thermomechanical load-induced deformation process. It is seen that this mechanism significantly reduces the lifetime of the rocket engine.

Besides the conceptual design by the engineer, a mathematical and theoretical study is necessary in optimization to compare with finite element analysis, to increase the life of a engine, the optimization method is used, which allows the improvement of a basic design and reduction in the design variables such as plastic strain and stress, temperature.

Bio-Physics · THEORETICAL PHYSICS - 1

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 in this age where we are into bionics, artificial intelligence, many 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 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 in my mind. But in reality, I’m not saying man can become immortal. But at least live longer with healthful life.

Let me go further, what is ageing 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. Cell dies, the effectiveness of our metabolism rate decreases [ I will share some posts about 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 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 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. Heart pumps the blood, like Pump transfer water or fluids. But it’s working is not same as our mechanical pump.

Heart contacts and relaxes, 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 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.
