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.


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.

Fabric of Space-Time [astrophysics] Part – 2

What is the best gift of modern physics?

Modern Physics has given the most valuable asset to the world of science. Principles that are used to describe our nature are limited. many laws are being stated and few of them succeed in proving them theoretically and sometimes experimentally, few are proved wrong.

One such curious concept read over decades, it’s also a mind-boggling concept. It is space – time. let’s see what I can say about it.

Do you know about space?

Space which is 3-Dimensional or multidimensional quantity along with planes in their curves [space-time fabric], entities will be much complex. Few people have believed that double slit experiment of physics leads to the wave nature of light, So usual science and its thoughts transformed then.

Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime.

space is everything in the universe beyond the top of the Earth’s atmosphere – the Moon, where the GPS satellites orbit, Mars, other stars, the Milky Way, black holes, and distant quasars. this statement defines space, which is rather part of the universe, not to consider as a physical quantity.

What about time? Good time, bad time

Time is a very fascinating thing in this universe, is that time what that clock shows? or time is beyond our imagination? research says, In the beginning of time there was a singularity, where our time started. but the concept of time breaks the laws of physics. many contradictory statements are noticed to say whether the time is absolute or time is relative. but anyway modern physics and its triumph in theoretical research declared time as a non-absolute quantity.

Time and space is a continuum, we don’t have proper evidence to say time is universal, In other words, since there is no universal time. we have no time, which we can synchronize clocks. In this real world, what we also call a macroscopic world, here it’s very difficult to notice.

but man made things like space vehicles and satellites which travel in space are synchronized. For GPS to work we must make sure those are adjusted to similar bending of space time to coordinates of systems present in the earth.

to be continued,

Whatever we see in this universe, everything is interconnected with Physical laws, they have Physical existence and physical significance in detail. I was fortunate enough to meet the legendary Bio-Physicist Wiliam Bialek, in the International center for theoretical science. Bangalore. I asked few doubts about Physics and its Interdisciplinary sciences they have worked. especially Biology and physics. Please find his lecture link below. excellent lecture ever heard about bio-physics. thank you ICTS for a wonderful lecture, and also I thank William Bialek an honorary physicist for wonderful session.

Some things about Bio-Physics

How we can Classify Bio-Physics?

Astro-biophysics It’s the of the field of connection between astrophysics and biophysics concerned with the influence of the Astrophysical phenomena upon life on planet Earth or some other planet in general. also, is concerned with the result of astrophysical procedures on life on Earth, as well as effects on likely life in any part of this universe.

Molecular Biophysics interdisciplinary field that applies methods and concepts from physics, chemistry, engineering, mathematics, and biology to comprehend biomolecular schemes and explain biological function in terms of molecular structure, structural organization, and dynamic behavior at various levels of complexity, from single molecules to supramolecular structures, viruses, and small living systems.

Medical biophysics an interdisciplinary field that applies approaches and concepts from physics to medicine or healthcare, ranging from radiology to microscopy and nanomedicine. See also, medical physics.

Clinical biophysics studies the procedure and effects of non-ionizing physical energies utilized for diagnostic and therapeutic purposes.

What is its application area?

biomolecular scale
Organismal scale
Environmental scale

Biophysics research has its research areas in Biochemistry, Bioengineering, Nanotechnology

What is Light ? [Philosophical view]

Light is more mysterious thing in universe…its source might be difficult to tell, a form of energy. all living beings, without light no life, no sight,no evolution may be in any part of the universe. light has got most significant role in our universe, without which evolution couldn’t be possible. 

In India, we celebrate festival of light called Deepawali / Diwali .One of the major festivals of Hinduism, it spiritually signifies the victory of light over darkness, good over evil, knowledge over ignorance, and hope over despair.

The name of festive days as well as the rituals of Diwali vary significantly among Hindus, based on the region of India. In many parts of India, the festivities start with Dhanteras (in Northern and Western part of India), followed by Naraka Chaturdasi on second day, Deepavali on the third day, Diwali Padva dedicated to wife–husband relationship on the fourth day, and festivities end with Bhai Dooj dedicated to sister–brother bond on the fifth day. Dhanteras usually falls eighteen days after Dussehra.

Festival of light across India and many places.

Many of worldwide religion got importance in celebration of light.Also in Egyptian civilizations used sun has their God….Sources of light and life.The figure below has clearly shows how an Nun, the embodiment of the primordial waters, lifts the barque of the sun god Ra into the sky at the moment of creation.

Sun a source of light

If we consider a future of earth The biological and geological future of Earth can be extrapolated based upon the estimated effects of several long-term influences. These include the chemistry at Earth’s surface, the rate of cooling of the planet’s interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun’s luminosity.Ancient days the speed and its properties are observed on the basis of physical existence…and more clearly i can say by observing nature of light.that what we see from our eyes.

Going back to ancient days..
Newton is one of them who started to observe the light from eyes differently..what a joke all we see from our eyes only..then what different newton had seen? 

confused , let me explain around 1690 AD newton started his studies on light.he used the special instrument called a days prism is common.but in 16th century,newton used it as one of great science device,to reveal the secrets of light. he saw not only light,but the color full light emerging from prism.(VIBGYOR)this is what i history mankind newton is the first person to observe,such phenomenon. for today its a simple thing. and started to give his conclusions.And written his book ‘Optics’.but let me give some properties which cannot be explained by just looking through naked eyes. Light can move through vacuum, Light transports energy , same as our sun provides energy to life on any planet  (if their are planets which have life other than earth ).

SCIENCE POINT : Light has angular momentum: it can rotate bodies, light being both particle and wave. It exhibits most quantum mechanical properties. Even our life sciences, polariser,  particle accelerator. .work only because of light’s this special property.Light has momentum: it can collide the particles.A special property friends my future blog will be on this,light moves with other light undisturbed..Light in outer-space moves faster than all objects in this universe.. The speed of light, its true signal speed, is the forerunner speed.299 792 458 m/s is the speed of light in vaccum. and 30c.m/n.s (30 centimeter per nano seconds.1/1000000000.The proper speed of light.another one a Shadows can move without any speed limit.

Light moves in a straight line when far from matter.High-intensity light is a wave.(credit:motion mountain_relativity),Light beams are approximations when the wavelength is neglected.In matter, both the forerunner speed and the energy speed of light are lower than in vacuum.In matter, the group velocity of light pulses can be zero, positive, negative or infinite.these are the properties of light which are gifts of quantum physics.or modern physics..the era of quantum physics was began in 1905(see my previous post for more information)this changed the world into quantum world.and some property of light is very strange and it was an miracle thing for ancients,hence may be miracle must be reveled as common things.

Light in Science
