One Voice in the Cosmic Fugue
The Early Earth
The meaning of fugue (fyoog) is a musical composition in which a short melody is successfully repeated by different voices or instruments. “Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live . In a hundred billion galaxies, you will not find another.”...Carl Sagan, Cosmos.

3. The early earth
carbon atom plays the central role in all complex or simple or microscopic beings.¬¬¬¬ Billions of years ago our earth was lonely and barren. There was no life. How the carbon based elements made? How did they come together to form a single cell... then multicellular organisms formed and complex beings as we came into existence?
4. Charles Darwin
Probably all the organic beings which have ever lived on this Earth have descended from some one primordial form into which life was first breathed—There is a grandeur in this view of life that, whilst this planet has gone cycling on according to the fixed laws of gravity from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.....Charles Darwin...The Origin of Species 1859”
5. Structure of DNA
According to the Research carried by Scientists & paeleantalogists our Earth was formed some 4.5 billion years ago. The Hydrogen rich molecules of the primitive Earth were broken due to lightening and ultra violet radiations.They recombined into more complex molecules they were the earliest ancestors of “deoxyribose neuclic acid”DNA the master molecule of Life on Earth.
6. paramecium
What is DNA? DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms It is located in the Nucleus.The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
7. dna cropped
The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences. The DNA molecule resembles like a spiral strands called double helix.
8. cosmos
The structure of the double helix is somewhat like a ladder, the rungs of this ladder is made of the four bases A(adenine)G(guanine)C(cytosine)T(Thymine) The sides of this ladder is made of sugar and phosphorus. Together a base sugar and phosphorus is termed nucleotide.
9. Paramecium
know from the fossil records that the origin of life happened soon after in ponds and oceans of the primitive Earth. The first organisms were unicellular (single cell) algae then by mutation they evolved to multi cellular .
10. unicellular organisms
Cambrian Explosion: Around 500 million years ago in the Cambrian era rocks the fossils of different animals were found at the floors of Cambrian oceans. It spoke about their existence. After the Cambrian Explosion new adaptations took place with speed. First fish and the first vertebrate appeared winged insects arose , amphibians creatures like lung fish who survived both on land and water .
11. single celled creatures
The first trees and the first reptiles emerged. The dinosaurs evolved the first mammals appeared. The first flowers and birds appeared; the dinosaurs became extinct , the earliest cetaceans, ancestors to the dolphins and whales, arose and in the same period primates the ancestors of monkeys the apes and the humans arose.. (Carl Sagan)
12. cosmos
Few million years ago the first true humans emerged. We have known and heard the voice of life on one small world only. Will we be able to hear the voice of life on other worlds? Although it may not be that easy but at least we have begun our search to listen for voices (extraterristial life) in cosmic fugue.
13. COSMIC SEARCH
The Title of my blog One Voice in the Cosmic Fugue is taken from Carl Sagans book COSMOS.

Time The Fourth Dimention
Few days back when i woke up i experienced that my head was spinning vigoresly.
I caught hold of my bed I thought i am travelling through a wormhole. Now i will land in another dimention...i had read...
I screamed my family came to help. I landed at doctors clinic, he pronounced that it was cervical spondylosis. I thanked almighty that i got well. My mind was thinking of the wormholes, time travel the dimentions.....
WHAT IS TIME?
In physics, time is described as a dimention much like length, width, and height.When you travel from your house to the grocery store, you are travelling through a direction in space, making headway in the spatial dimention -length width and height. But you are also travelling forward in time, the fourth dimention.(Sara Goudarzi)
What does a dimention mean?
A dimention is a degree of freedom of a system. In simple words it is a numberof ways or direction in which change can take place in a system. we can understand by the following example.
Imagine an ant walking on a thread. It can move forward and backward only.It cannot move side ways That means its degree of freedom of movement is in one dimention only. Now imagine that ant is placed on a flat surface. It can move forward sideways but not upwards or downwards. That means its degree of freedom of movement is two dimention. Now imagine an ant has wings . Its degree of freedom of movement is upwards downwards sideways forward and backwards. Therefore its degree of freedom of movement is three dimention like us.
Bob Singer NASA Engineer says , an object that actually exits from the time it came into existantance until it ceases to exist has a duration the fourth dimention.
That means the ant that was moving on the thread had not one but two dimention one was space and the other time. In the same way we live in this world in three dimentions plus one time dimention.
Special relativity propounded by Einstein demolished the concept
of absolute time. He unified time and space terming spacetime
He termed it as our fourth dimention. In space we can move forward and backwards but dimention of space time we can move in
one direction that is forward only. the concept of time dilation in special relativity t ells us that time slows down for an object as it speeds up to the speed of light. For example, a person A who is travelling in space with a speed of light, and a person B who is stationary B on Earth, the person A who returns to Earth say after five years in space sees that the person B on Earth has aged in decades. The faster you move the slower time changes for you! It is a fact which has been verified through experiments.
Time is unique dimention you can move in one direction that is forward you cannot move backward.
Can we Time Travel?
Time Travel has been mans wildest fantasies for centuries..
H. G Wells "The Time Machine" and the latest fiction movie "INTERSTELLAR"
Intersteller is a science fiction the film is directed by Chritopher Nolan the film features a crew of astronauts who travel through a wormhole in search of a new home for humanity.


(Matthew McConaughey and Anne Hathaway star as Joseph "Coop" Cooper and Dr. Amelia Brand respectively.)
According to Einstein's theory of general relativity, a wormhole could act like a bridge though space-time by connecting two distant points with a shortcut the Einstein Rosen bride in 1935.
In the late 1980s, Thorne said that a wormhole could be made into a time machine.

Colonizing the Planet Mars
1. Our life when we colonize on Mars
Colonizing Mars. With the release of Ridley Scott’s movie The Martian
on 2nd oct. it is acclaimed that it is one of the most realistic
portrayals of human space exploration ever filmed. Based on the 2011
science fiction novel by Andy Weir the film stars Matt Damon as Mark
Watney,a botanist turned astronaut marooned on Mars. He was accidently
left behind by his crewmates. The Ares III manned mission to Mars is hit
by intense storm Mark Watney is lost and presumed that he is dead. The
mission commander Mellisa Leewis is forced to leave the planet as the
rest crews lives were at stake.
2. An Artists view of Mars Colony
As NASA workers struggle to launch a mission to bring him back home,
Watney improvises one ingenious scheme after another to stay alive. He
turns his habitat into a chemistry lab and a greenhouse, extracting
potable water from rocket fuel and growing potatoes in nutrient-poor
Martian soil fertilized with his own feces.
3. An Artists concept of Colonized Mars
Coming to the fact and not fiction, NASA has plans to send men on
Mars in 2030. “Journey to Mars Programme.” Its facing quite big other
problems inspite of the advanced Technology and accuracy they have
developed.
4. Terraforming
The recent discovery of water on Mars has developed hopes of
colonizing humans on Mars. Terraforming .. Mars is more suitable for
human inhabitation than any other planet or our moon. NASA’s robotic
mission, the ‘Mars Exploration Rovers’ has sent unmanned rovers,
‘Spirit’ and ‘Opportunity’ and Curiosity.
5. Marsone astronaut
There are Many similarities between Mars and Earth that make viable
options for colonization . for eg, Nearly similar lengths of days….Axial
tilt is similar therefore basic seasonal patterns as Earth (albeit for
longer periods of time). Mars is in Suns habitable zone Goldilock zone.
But Mars has 95% carbon dioxide . Mars has no global magnetic field , to
protect from radiations pouring in its thin atmosphere. It will be a
herculean task to create oxygen for breathing and growing crops for
surviving on Mars.
6. ELON MUSK
Advocating Colonization of Mars ‘Mars Society’, an organization
founded by Robert Zubrin, promotes and advocates the colonization of
Mars. It was established in 1998 and does the work of educating people
and governments about benefits of space exploration and colonization of
Mars.
7. PLANET MARS
‘Mars Drive’ is another group that supports space exploration and
colonization of Mars. Founded in 2005, this group has spread out in
Europe, North America and Australia. ELON Musk stated that the goal of
Space x is to help humans to get to Mars . They are designing rockets
landers and equipment to support this. Musk would like to build a Mars
colony with 80,000 people second most habitable place in the solar
system. Let us hope that humans make another (second giant)leap for the
Mankind by Colonizing Mars.

THE ENCOUNTER!
THE ENCOUNTER
(Its a true story of my Father in Law)
A six year old boy was playing in the backyard of his house. There
stood an iron pole inserted vertically. The children used to climb up
and then slide down. The elder ones performed all sorts of exercises.
But that day he was all alone. He found a leather belt. He held
it tightly in his little hand and started whipping the pole
relentlessly.. His mother stood at the doorstep watching him. He
whipped the pole again and again murmuring “why did you kill my father.”
He was red with rage. Not knowing the child’s sudden behavior she
rushed at him. He screamed “why did you kill my father.” The words
deafened her ears and she consoled her young one took him in her arms.
She knew she could not bring back his father. Her husband would never
return! He was killed by the dacoit.
Her husband was an Inspector in the Police force. He was posted at
Badnaver, in Madhya Pradesh. Everybody addressed him as Raosaheb.
Raosaheb was very handsome strongly built and a brave person. He
caught hold of dangerous thieves and vagabonds and put them behind the
bars.
life went on.. he found a beautiful lady fell in love and
eventually married her. They were blessed with five children. As soon
as he returned home from his tour, the children would cluster round him.
He played with them. He would pick the young ones and swing them on his
arms. Their reverberating laughter and chuckles freshened him up.
Night was pleasant to be in parents arms. This bliss lasted for a
very short period. The darkness enveloped the twinkling stars which
foretold a grievous future for the family.
That very night the Inspector spoke to his wife about his plans to
catch the dacoit. A pall of gloom spread over her. She was
dumbfounded as all her plans to desist him from venturing his arduous
task.
Parting with his dear ones he strode away in the eerie jungles with
his small coup—a handful of men and meager ammunition. The dense
forest near Badnawar in Madyapradesh was the dacoit’s hideout. They
drove in the deep forests in bullocarts – it was the only means to
travel in those days. The narrow lanes of the village, after village
was traversed until one village was spotted for supplying huge amount of
chicken meat and wines. At ones the Inspector acumen directed his men
towards that place. soon they confronted a fierce looking person clad
in military uniform with broad mustache. No doubt that he was the
famous dacoit Nathakanjar the most wanted by the police force. He was
surrounded by his men.. They were well equipped with ammunition. He
roared aloud to bring the Inspector before him. After much
interrogation the dacoit had insisted the Inspector to give up his
Police uniform his belt and guns and surrender before them. The brave
Inspector preferred to fight with him unto his death. It would be an
insult to his profession to go back and cowardly submit to the dacoit’s
demands. A fierce battle raged between the two troops. A sepoy who fled
for his life had climbed a tree and saw the drama with his naked eye.
He was a sole survivor and later narrated the whole incident to the
family members and the villagers all that had transpired between the two
parties. The fearless Inspector was none other than the little boy’s
father.
The body of Raosaheb was brought home and laid for last darshan.
The small boy caught hold of his weeping mother’s hand, consoled her and promised to take care of her henceforth.
The heavens rumbled as the guns were fired..a mark of salutations for the Martyr. The last rights were performed..
Years later,
the promise he had made to his mother had been fulfilled when his
mother breathed last. A huge void left him, but this time he was not
alone, his better half held him to share his griefMonday, June 8, 2015
THE SHORES OF THE COSMIC OCEAN

The Shores of the Cosmic Ocean
“The surface of the Earth is the Shore of the Cosmic Ocean. Recently we have waded a little out to Sea, enough to dampen our toes or, at most,wet our ankles. The water seems inviting. The Ocean calls. Some part of beings knows this is from where we came. We long to return”….(Carl Sagan)

Welcome to this beautiful Planet Earth. It’s full of Life a place of blue nitrogen skies oceans of liquid water cool forests and soft meadows. In all our journeying through space and time this place is unique and rare. There must be many such worlds scattered through space but we have yet to find life elsewhere. With the accumulated knowledge from our ancestors
over million years, we have begun our voyage to home from where we
humans are born from stars and now inhabiting a world called Earth. .Carl says
Something in us recognizes the Cosmos as home. We are made of stellar ash. Our origin and evolution have been tied to distant cosmic events. The exploration of Cosmos is a voyage of Self –discovery…..
Our History:
During third B.C. in Egyptian city of Alexandria, was flourished with scholars.
Eratosthenes was a one of them. He was a Greek astronomer historian geographer philosopher poet theatre critic and mathematician. He was the director of the the great ‘Library of Alexandria’. He deduced with experiment that our Earth is round(360 degrees) and not flat. He calculated its circumference very correctly. ..40,000kms. Its very interesting about his discovery… He had read in one of the papyrus book from the Library that at southern frontiers outpost of Syene at noon on June 21 vertical sticks casts ‘no’ shadows. He observed that in Alexandria that the vertical sticks did cast shadows at noon on June 21. A very simple experiment with these sticks he calculated that the surface of Earth is curved and not flat which was presumed. The sun is far away its rays are parallel when they strike the Earths .Sticks placed at the different angle to the sun rays casts shows of different lengths .(see dia.1) For the observed differences of the shadow lengths, the distance between Alexandria and Syene had to be about seven degrees along the surface of the Earth
.
Seven degree is 1/50 of three hundred and sixty degrees Eratostheses
quoted. How very correct his calculations were 2200 years ago. Really
Amazing!The city was founded by Alexander the Great. Alexander encouraged knowledge from all around the world. He respected their Gods and Culture. The greatest marvel during his rule was the Library of Alexandria. He invited great scholars from India China Japan etc.etc. The Greek kings of Egypt who succeeded Alexander supported research and entertained the best minds for centuries. The Alexandrian Library is where we humans first collected seriously and systematically the knowledge of the world.
Seven centuries after its founding a Greek female Scholar Hypatia a mathemation philosophe
r
an astronomer surpassed the philosophers of her time. Around 400 AD she
became the head of Platonist school of Alexandria and taught the
knowledge of Plato and Aristotle. Egypt then was ruled by Romans. By
contemporary sources it is said that she was brutally murdered. The
Library of Alexandria was destroyed…Hypatia was the last light of the Library.
Socrates has written about her in his Ecclesiastical History.
We shall see more about these Scientist and Philosphers in coming
blogs..

WHAT IS GRAVITY?
May 3, 2015
What is GRAVITY?
In the year 2013 a Science fiction movie GRAVITY was awarded with OSCAR My daughter persuaded us to see this movie on big screen in Cinema Hall to get the 3D effect. It was amazing to see a Medical Engineer Astronaut Dr. Ryan Stone (Actress Sandra Bullock) and a veteran Astronaut Matt Kowalsky (Actor George Clooney) on a space shuttle to repair the damaged Hubble Telescope. During their space walk , disaster strikes their shuttle and other crew members gets destroyed leaving the two astronauts stranded in Space. No link with the Earth, the terrifying expanse of space how they make to International Space Stations and another Chinese Space station close by…
and board a Soyuz model and return home (Earth).A unique grand movie
Everything floats in Space as there is no Gravity there.
Due to this gravity we have a firm foothold on Earth. What will be Life without this force?
I kept pondering…
Had learnt about Newton’s Laws of Gravitation in School…
Sir Isaac Newton (25 December1642-20 March 1726) was an English Physicist and Mathematician one of the most influential scientist of all times.

What is Gravity?
Gravity is an invisible force that pulls/attracts all matter towards itself. But this force is very very weak that is why the matter does not get pulled with other objects. The fundamental forces of the universe include the electromagnetic, strong nuclear, weak nuclear and gravitational forces. Gravity is the weakest of all but in cases where matter is involved in massive quantities (for example: a black hole), it is the strongest and most dominant one. Gravity is the reason everything gets attracted towards the Earth’s surface, and also for the formation and movement of all the planets and other heavenly bodies.

(Gravity keeps the moon where it’s supposed to be — in orbit.

Gravity also is important on a larger scale. It is the Sun’s gravity that keeps the Earth in orbit around the Sun; otherwise Earth would fling drifting in space. Life on Earth needs the Sun’s light and warmth to survive. Gravity helps the Earth to stay just the right distance from the Sun, so it’s not too hot or too cold. It’s the Earth’s gravity that keeps the moon in orbit around the Earth.

.
Isaac Newton discovered Gravitational Force
Newton’s law of universal gravitation, which postulates that the gravitational force of two bodies of mass is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. He also postulated the Law of Motion.
Gravitational Force = G* ___(M1*M2) ______________
(d2)
where ‘G’ is the gravitational constant, ‘m1′ and ‘m2′ are the masses of the two objects, for which the force has to be calculated, and ‘d’ is the distance between the centers of gravity of both masses.
Albert Einstein:
In modern physics, gravity is most accurately described by the general theory of relativity (proposed by Einstein) which describes gravity as a consequence of the curvature of spacetime. (Albert Einstein called gravity a distortion in the shape of space-time. Photo by keystone/getty images)
In 1806, a British physiologist called A. Knight demonstrated through an experiment, the control of gravity on the direction of a plant’s root growth. The term geotropism was first coined by A. B. Franck in 1868. It is a growth movement by a plant in response to gravity.

If you were to put a plant on its side you would notice that after a while the roots start growing downward while the stem grows upward. This response to gravity is called geotropism, or gravitropism. The roots are exhibiting positive geotropism (growing with gravity) and the stem is exhibiting negative geotropism (growing against gravity).

Fun facts about gravity:
Ocean tides are caused by the gravity of the moon.
Mars is smaller and has less mass than Earth. As a result it has less gravity. If you weigh 100 pounds on Earth, you would weigh 38 pounds on Mars. Moon
