"India is the world's most ancient civilization. Nowhere on earth can you find such a rich and multi-layered tradition that has remained unbroken and largely unchanged for at least five thousand years. Bowing low before the onslaught of armies, and elements, India has survived every invasion, every natural disaster, every mortal disease and epidemic, the double helix of her genetic code transmitting its unmistakable imprint down five millennia to no less than a billion modern bearers. Indians have demonstrated greater cultural stamina than any other people on earth. The essential basis of Indian culture is Religion in the widest and most general sense of the world. An intuitive conviction that the Divine is immanent in everything permeated every phase of life," says Stanley Wolpert. 

Indic civilization has enriched every art and science known to man. Thanks to India, we reckon from zero to ten with misnamed "Arabic" numerals (Hindsaa - in Arabic means from India), and use a decimal system without which our modern computer age would hardly have been possible.

Science and philosophy were both highly developed disciplines in ancient India. However, because Indian philosophic thought was considerably more mature and found particular favor amongst intellectuals, the traditions persists that any early scientific contribution came solely from the West, Greece in particular. Because of this erroneous belief, which is perpetuated by a wide variety of scholars, it is necessary to briefly examine the history of Indian scientific thought. Jawaharlal Nehru wrote in his book The Discovery of India:  "Till recently many European thinkers imagined that everything that was worthwhile had its origins in Greece or Rome ." From the very earliest times, India had made its contribution to the texture of Western thought and living. Michael Edwardes, author of British India, writes that throughout the literatures of Europe, tales of Indian origin can be discovered. European mathematics  - and, through them, the full range of European technical achievement – could hardly have existed without Indian numerals. But until the beginning of European colonization in Asia, India’s contribution was usually filtered through other cultures.

"Many of the advances in the sciences that we consider today to have been made in Europe were in fact made in India centuries ago." - Grant Duff British Historian of India. Dr. Vincent Smith has remarked, "India suffers today, in the estimation of the world, more through the world's ignorance of the achievements of the heroes of Indian history than through the absence or insignificance of such achievement."

Introduction

According to American Historian Will Durant in his book, The Story of Civilizations - Our Oriental Heritage ISBN: 1567310125 1937 p.391-396:

"From the time of Megasthenes, who described India to Greece ca 302 B.C., down to the eighteenth century, India was all a marvel and a mystery to Europe. Marco Polo (1254-1323) pictured its western fringe vaguely, Columbus blundered upon America in trying to reach it, Vasco da Gama sailed around Africa to rediscover it, and merchants spoke rapaciously of "the wealth of the Indies." 

" It is true that even across the Himalayan barrier India has sent to us such questionable gifts as grammar and logic, philosophy and fables, hypnotism and chess, and above all our numerals and our decimal system. But these are not the essence of her spirit; they are trifles compared to what we may learn from her in the future. As invention, industry, and trade bind the continents more closely, and shall absorb, even in enmity, some of its ways and thoughts." 

"The indications are that Mohenjadaro was at its height when Cheops built the first great pyramid; that it had commercial, religious and artistic connections to Sumeria and Babylonia...as Sir John Marshall believes, Mohenjadaro represents the oldest of all civilizations known."

Yaqubi (9th century) Muslim historian has written: 

"The Hindus are superior to all other nations in intelligence and thoughtfulness. They are more exact in astronomy and astrology than any other people. 

"The Siddhanta is a good proof of their intellectual powers; by this book the Greeks and Persians have also profited. In medicine their opinion ranks first."

Al-Jahiz 9th century Muslim historian writes:

"The Hindus excel in astrology, mathematics, medicine and in various other sciences. They have developed to a perfection arts like sculpture, painting, and architecture. They have collections of poetry, philosophy, literature and science of morals. From India we received the book called Kalilah wa Dimnah. These people have judgment and are brave. They posses the virtues of cleanliness and purity. Contemplation has originated with them."

(source: The Vision of India - By Sisirkumar Mitra p. 226).

The medieval Arab scholar Sa'id Ibn Ahmad al-Andalusi (1029-1070) wrote in his Tabaqat al-'umam, one of the earliest books on history of sciences:

"The first nation to have cultivated science is India. ... India is known for the wisdom of its people. Over many centuries, all the kings of the past have recognized the ability of the Indians in all the branches of knowledge... The kings of China have stated that the kings of the world are five in number and all the people of the world are their subjects. They mentioned the king of China, the king of India, the king of the Turks, the king of the Persians, and the king of the Romans... They referred to the king of India as the "king of wisdom" because of the Indians' careful treatment of ulum (sciences) and all the branches of knowledge. ... The Indians, known to all nations for many centuries, are the metal (essence) of wisdom, the source of fairness and objectivity. They are people of sublime pensiveness, universal apologues, and useful and rare inventions. ... To their credit the Indians have made great strides in the study of numbers and of geometry. They have acquired immense information and reached the zenith in their knowledge of the movements of the stars (astronomy).... After all that they have surpassed all other peoples in their knowledge of medical sciences.."

“That which has reached us from the discoveries of their clear thinking and the marvels of their inventions is the (game) of chess. The Indians have, in the construction of its cells, its double numbers, its symbols and secrets, reached the forefront of knowledge. They have extracted its mysteries from supernatural forces. While the game is being played and its pieces are being maneuvered, there appear the beauty of structure and the greatness of harmony. It demonstrates the manifestation of high intentions and noble deeds, as it provides various forms of warnings from enemies and points out ruses as well as ways to avoid dangers. And in this, there is considerable gain and useful profit.”

Abu’l Hasan al-Qifti ( ? ) Arab scholar and author of Chronology of the Scholars, speaks of  Arab admiration for Indian place-value system and methods of calculation.

“Among those parts of their sciences which came to us, the numerical calculation….it is the swiftest and most complete method of calculation, the easiest to understand and the simplest to learn; it bears witness to the Indians’ piercing intellect, fine creativity and their superior understanding and inventive genius.”

Sir William Wilson Hunter ( ? )author of the book, The Indian Empire, said India," has even contributed to modern medical science by the discovery of various chemicals and by teaching you how to reform misshapen ears and noses. Even more it has done in mathematics, for algebra, geometry, astronomy, and the triumph of modern science -- mixed mathematics -- were all invented in India, just so much as the ten numerals, the very cornerstone of all present civilization, were discovered in India, and are in reality, Sanskrit words."

Beginning with the earliest known Indian civilization, the Indus Valley, with its pottery wheel, cotton textiles, Indus script, and two wheeled carts, there is a good deal of material and texts to work from. By the beginning of the third millennium B.C. in India, as in China, Egypt, and Mesopotamia, scientific development was well advanced. Excavations carried on at the sites of the Indus civilization have revealed remnants of an ancient civilization unsurpassed in civil engineering accomplishments, particularly baths and drainage. Whilst much is known of the hygienic measures of the period, little is known of the scientific knowledge upon which it was based. From the town Planning and Great Baths of Indus Valley it is evidence in the neat arrangement of the major buildings contained in the citadel, including the placement of a large granary and water tank or bath at right angles to one another. The lower city, which was tightly packed with residential units, was also constructed on a grid pattern consisting of a number of blocks separated by major cross streets. Baked-brick houses faced the street, and domestic life was centered around an enclosed courtyard. The cities had an elaborate public drainage system, Sanitation was provided through an extensive system of covered drains running the length of the main streets and connected by chutes with most residences. In the valley of the Indus River of India, the world's oldest civilization had developed its own system of mathematics. 

This civilization is known for its well planned cities, brick built houses, excellent drainage system and water storage tanks. Benjamin Rowland (1904-1972) author of Art and Architecture of India wrote: "Indeed it could be said that the population of the Indus cities lived more comfortably than did their contemporaries in the crowded and ill-built metropolises elsewhere. People were literate and had their own script. Dance and music formed essential part of their daily life."

They had wide main streets and were magnificently laid out in grid form, reflecting careful town planning. They had sewers, municipal water systems, public baths, and well-fortified citadels. The private houses were well built, of fine solid baked bricks which have not crumbled over the centuries. Many of them were two stories high, and had seat latrines and chutes for refuse. Homes were built around courtyards. The people of the Indus Valley civilization had an advanced technology. They knew how to make cotton cloth and copper and bronze castings and forgings. Some of their art objects have a wonderful simple realism. The torso of one small dancing figure is so unbelievably alive that one can almost feel the easy muscles at work under the smooth skin. 

(source: India: A World in Transition - By Beatrice Pitney Lamb p. 20).

"Mohenjo-daro had some of the most advanced toilets and sewers, with lavatories built into the outer walls of houses. There were “Western-style” toilets made from bricks with wooden seats on top. They had vertical chutes, through which waste fell into street drains or cesspits. Sir Mortimer Wheeler, the director-general of archaeology in India from 1944 to 1948, wrote: “The high quality of the sanitary arrangements could well be envied in many parts of the world today.” 

Nearly all of the hundreds of houses excavated had their own bathing rooms. Generally located on the ground floor, the bath was made of brick, sometimes with a surrounding curb to sit on. The water drained away through a hole in the floor, down chutes or pottery pipes in the walls, into the municipal drainage system. Even the fastidious Egyptians rarely had special bathrooms."

The Indian architects designed sewage disposal systems on a large scale, building networks of brick effluent drains following the lines of the streets. The drains were seven to ten feet wide, cut at two feet below ground level with U shaped bottoms lined with loose brick easily taken up for cleaning. At the intersection of two drains, the sewage planners installed cesspools with steps leading down into them, for periodic cleaning. By 2700 B.C. these cities had standardized earthenware plumbing pipes with broad flanges for easy joining with asphalt to stop leaks."  

The Harappans employed a variety of plumb bobs that reveal a system of weight based on a decimal scale. For example, a basic Harappan plumb bob weighs 27.584 grams. If we assign that a value of 1, other weights scale in at 0.5, .1., 2, .5, 2, 5, 10, 20 50, 100, 200, and 500. Archaeologists have found a “ruler” made of shell lines drawn 6.7 millimeters apart with a high degree of accuracy. Two of the lines are distinguished by circles and are separated by 33.5 millimeters or 1.32 inches. This distance is the so-called Indus inch.

Harappan bricks contain no straw or binding material and are still in usable shape after five thousand years. Most interesting are their dimensions: while found in fifteen different sizes, their length, width, and thickness are always in the ration of 4:2:1.

In ancient India, as in Greece, there was much speculative thought about astronomy, mathematics, physics, and biology. But mathematics and mysticism were inextricably mixed in early Greek thought, and Greek belief in magic, divination and oracles was perhaps more pronounced than its counterpart in India.

It is therefore untrue to assert, as recent European writers particularly have done, that Greece was the home of pure science. 

Both India and Greece, whilst having their own traditions, had direct and indirect effects on each other in science as they did in philosophy. In fact, long before the Greeks, the Indians had learned to employ the dialectic method to grasp empirical and transcendental truths, although in India, more perhaps than in ancient Greece or the modern West, reason and truth, logic and mysticism, the visible and invisible, have always been regarded as inseparable. The practical application of science to human affairs, was as poor in India as it was in any other ancient society. In fact, this was not achieved until the eighteenth century, until then science and technology developed separately.
When it did as in the case of Galileo Galilei, who was the first to employ the modern scientific method in its fullness, he incurred the wrath of the Church and was incarcerated by the Inquisition at the advanced age of seventy. There is hardly any parallel in India where a difference in interpretation either in metaphysics or scientific thought was so unkindly suppressed. 

The spirit of scientific enquiry and a rigorous correlation of cause and effect in explaining natural phenomenon were particularly evident in ancient India. The connection between Indian philosophy and medicine, mathematics, astronomy, and technology is, strangely enough seldom realized much less recognized.

Ancient Indians "measured the land, divided the year, mapped out the heavens, traced the course of the sun and the planets through the zodiacal belt, analyzed the constitution of matter, and studied the nature of birds and beasts, plants and seeds." Whilst in Western civilizations the  interest has been increasingly focused on single sciences, in the Indian world the ontological viewpoint has been generally preferred, and it would appear that "in India, through all periods,  the special sciences are rooted in and developed on the underlying cosmic concepts and presuppositions. This universal vision in India has never been lost. 

India's contribution to the sciences of mathematics and medicine have been unique. In other sciences, especially linguistics, metallurgy, and chemistry, Indians made trail-blazing discoveries. 

(source: An Introduction to India - By Stanley Wolpert  p. 192).

The Vedic Shulba Sutras (fifth to eighth century B.C. E.) meaning "codes of the rope," show that the earliest geometrical and mathematical investigations among the Indians arose from certain requirements of their religious rituals. When the poetic vision of the Vedic seers was externalized in symbols, rituals requiring altars and precise measurement became manifest, providing a means to the attainment of the unmanifest world of consciousness. "Shulba Sutras" is the name given to those portions or supplements of the Kalpasutras, which deal with the measurement and construction of the different altars or arenas for religious rites. The word Shulba refers to the ropes used to make these measurements. Although Vedic mathematicians are known primarily for their computational genius in arithmetic and algebra, the basis and inspiration for the whole of Indian mathematics is geometry. Evidence of geometrical drawing instruments from as early as 2500 B.C.E. has been found in the Indus Valley.

The beginnings of algebra can be traced to the constructional geometry of the Vedic priests, which are preserved in the Shulba Sutras. Exact measurements, orientations, and different geometrical shapes for the altars and arenas used for the religious functions (yajnas), which occupy an important part of the Vedic religious culture, are described in the Shulba Sutras. Many of these calculations employ the geometrical formula known as the Pythagorean theorem.

This theorem (c. 540 B.C.E.), equating the square of the hypotenuse of a right angle triangle with the sum of the squares of the other two sides, was utilized in the earliest Shulba Sutra (the Baudhayana) prior to the eighth century B.C.E. Thus, widespread use of this famous mathematical theorem in India several centuries before its being popularized by Pythagoras has been documented. The exact wording of the theorem as presented in the Sulba Sutras is: "The diagonal chord of the rectangle makes both the squares that the horizontal and vertical sides make separately." The proof of this fundamentally important theorem is well known from Euclid's time until the present for its excessively tedious and cumbersome nature; yet the Vedas present five different extremely simple proofs for this theorem. 

One historian, Joseph Needham, has stated, "Future research on the history of science and technology in Asia will in fact reveal that the achievements of these peoples contribute far more in all pre-Renaissance periods to the development of world science than has yet been realized." 

Meticulous planning and architectural brilliance in the layout of the city are the established and striking features of the Harappan civilisation. 

Recent excavations at the small township of Dholavira, in Kutch, Gujarat, have presented to the world some of the oldest stadiums and sign board.  

One of the stadiums is huge. The multipurpose structure, with terraced seats for spectators, around 800 feet in length (around 283 metres) can accommodate as many as 10,000 persons. The other stadium is much smaller in size.    

The dimensions of the town of Dholavira (777.1 metres in length and 668.7 meters in width) establishes that the Harappans had great knowledge of trigonometry.   They were also mathematical experts as all the dimensions at the site are based on squares and cubes, 

(source: Oldest Harappan signboard at Kutch township - timesofindia.com). 

Ancient Indians already operated with a time span of astronomical proportions long before the earliest signs of natural science in ancient Greece. It is undeniable that ancient Indian texts present astonishingly exact scientific calculations even by today's latest scientific standards, such as the speed of light, exact size of the smallest particles and the age of the universe. 

The Surya Siddhanta, a textbook on astronomy of ancient India - last compiled in 1000 BC, believed by Hindus to be handed down from 3000 BC by aid of complex mnemonic recital methods still known today - computed the earth's diameter to be 7,840 miles, the distance earth - moon as 253,000 miles. These compare to modern measurements resp. as 7,926.7 miles and 252,710 miles for max. dist. moon-earth.

Manu's texts in Sanskrit propounded evolution thousands of years before Lamarck & Darwin. "The first germ of life was developed by water and heat. Man will traverse the universe, gradually ascending and passing through the rocks, the plants, the worms, insects, fish, serpents, tortoises, wild animals, cattle, and higher animals. These are the transformations declared, from the plant to Brahma, which have to take place in the world."

Brihath Sathaka operates with divisions of the time of one day into:- 60 kalas or ghatika - 24 mins each. Subdivided into 60 vikala (24 secs.each) 60 para then into tatpara, then into vitatpara then into ima then into kasha.... the smallest unit, equal to approx. o.ooooooo3 of a second (one 300 millionth). This smallest unit (3 X 10 -8 second) is surprisingly close to the life-spans of certain mesons and hyperons, according to some Western physicist who was interviewed on the BBC World Service in the early 1990s. 

The 14th century 'Rigveda of the Sun' (dated by manuscript age only), says that the sun covers 2,202 yoganas in half a mimesa - which calculates as 300,000 metres a second, fairly exactly the speed of light.

Francois Marie Arouet Voltaire (1694-1774) France's greatest writers and philosophers, was a theist, and a bitter critic of the Church said :

" It is very important to note that some 2,500 years ago at the least Pythagoras went from Samos to the Ganges to learn geometry...But he would certainly not have undertaken such a strange journey had the reputation of the Brahmans' science not been been long established in Europe....We have already acknowledged that arithmetic, geometry, astronomy were taught among the Brahmans. From time immemorial they have known the precession of the equinoxes and were in their calculation far closer to the real figure than the Greeks who came much later. Mr. Le Gentil (a French astronomer who spent several years in India) has with admiration acknowledged the Brahmans' science, as well as the immensity of time these Indians must have needed to reach a knowledge of which even the Chinese never had any notion, and which was unknown to Egypt and to Chaldea, the teacher of Egypt."

Beginning of Indian Scientific Thought

The beginning of Indian scientific thought are traced to the same source as those of Indian metaphysics and religion, the Rig Veda. The Vedas, being essentially works of poetic imagination, cannot be expected to contain much spirit of scientific inquiry, yet there are remarkable flashes of intuitive conjecture and reason. 
They explain the nature of the universe, of life, while admitting that Creation itself is the one unknowable mystery. 
To the Vedic sages, creation indicated that point before which there was no Creator, the line between indefinable nothingness and something delineated by attributes and function, at least. Like the moment before the Big Bang Theory. These concepts preoccupy high wisdom, the Truth far removed from mere religion.  

Indeed, in one of the most remarkable of the Vedic hymns - In the Hymn of Creation (Rig Veda 10.129.3)   a searching inquiry as to the origin of the world is made; it is certainly the earliest known record of philosophic doubt. 
            

" There was not non-existent nor existent;
There was no realm of air, no sky beyond it.
What covered it, and where? and what gave shelter?
Was water there, unfathomed depth
of water?

 

Yet the Vedas go further, being philosophy, or really spiritual sciences, rather than myth.  The hymn goes to say that in the beginning there was neither death nor immortality, nor day nor night. All that existed was void and formless. Then arose, desire, the primal seed and germ of spirit. But, 

Who verily knows and
who can declare it,
Whence it was born and
Whence comes this creation?

The gods are later than this
world's production
Who knows, then, whence it
first came into being?

Vedas are the most sophisticated, most profoundly beautiful, and most complete presentations of what Aldous Huxley termed the “perennial philosophy” that is at the core of all religions. In modern academia, of course, there is not supposed to be any “ancient wisdom”.  In this hymn, which contains the essence of monism, can be seen a representation of the most advanced theory of creation. The germ of free speculation and skepticism were already present in the Rig Veda. 

(source: The Empire of the Soul: Some Journeys into India - By Paul William Roberts  published by Riverhead Books ASIN: 1573226351 p 300-301).

The statue of Nataraja (dance pose of Lord Shiva) is a well known example for the artistic, scientific and philosophical significance of Hinduism. 

Freedom was born in India. Doubt, the mother of freedom, was born with the Rig Veda, the most sacred scripture of the Hindus which has the following:

What are words, and what are mortal thoughts!
Who is there who truly knows and who can say,|
Whence this unfathomed world
And from what cause!

Freedom of the mind created the wondrous world of the intellect — the world of Hindu rishis, philosophers, poets and dramatists. It was the freedom of the mind and freedom of the senses which led to India’s diversity and contributed to the richness of its civilization. No other civilization, not even that of the Greeks, could have enjoyed the freedom that we had. We have to remember, Socrates was forced to drink hemlock! The Inquisition burnt the Christian apostates at the stake and Islam beheaded dissenters.

Concept of Time

"After a cycle of universal dissolution, the Supreme Being decides to recreate the cosmos so that we souls can experience worlds of shape and solidity. Very subtle atoms begin to combine, eventually generating a cosmic wind that blows heavier and heavier atoms together. Souls depending on their karma earned in previous world systems, spontaneously draw to themselves atoms that coalesce into an appropriate body." - The Prashasta Pada.

***

Grandiose time scales

Hinduism’s understanding of time is as grandiose as time itself. While most cultures base their cosmologies on familiar units such as few hundreds or thousands of years, the Hindu concept of time embraces billions and trillions of years. The Puranas describe time units from the infinitesimal truti, lasting 1/1,000,0000 of a second to a mahamantavara of 311 trillion years. Hindu sages describe time as cyclic, an endless procession of creation, preservation and dissolution. Scientists such as Carl Sagan have expressed amazement at the accuracy of space and time descriptions given by the ancient rishis and saints, who fathomed the secrets of the universe through their mystically awakened senses.

(source: Hinduism Today April/May/June 2007 p. 14).

As in modern physics, Hindu cosmology envisaged the universe as having a cyclical nature. The end of each kalpa brought about by Shiva's dance is also the beginning of the next. Rebirth follows destruction.

wpe32.jpg (3455 bytes)The transcendence of time is the aim of every Indian spiritual tradition. Time is often presented as an eternal wheel that binds the soul to a mortal existence of ignorance and suffering. "Release" from time's fateful wheel is termed moksha, and an advanced ascetic may be called kala-attita (' he who has transcended time').

Hindus believe that the universe is without a beginning (anadi= beginning-less) or an end (ananta = end-less).  Rather the universe is projected in cycles.

Time immemorial is measured in cycles called Kalpas. A Kalpa is a day and night for Brahma, the Lord of Creation. After each Kalpa, there is another Kalpa. Each Kalpa is composed of 1,000 Maha Yugas. 

A Kalpa is thus equal to 4.32 billion human years. Kirtha Yuga or Satya yuga (golden or truth age) is 1,728,000 years; Treta yuga is 1,296,000 years; Dvapara yuga is 864,000 years; and Kali Yuga is 432,000 years. Total duration of the four yugas is called a kalpa.  At the end of kalyuga the universe is dissolved by pralaya (cosmic deluge ) and another cycle begins. Each cycle of creation lasts one kalpa, that is 12,000,000 human years ( or 12,000 Brahma years).

One Maha Yuga is 4,32 million years.  

Krita or Satya  golden age  1,728,000 years
Treta silver age 1,296,000 years
Dvapara copper age 864,000 years
Kali  iron age 432,000 years

 
A Brahma, or Lord of Creation, lives for one hundred Brahma years (each of made up of 360 Brahma days). After that he dies. So a Brahma lives for 36,000 Kalpas, or 36,000 x 2,000 x 4,30,000 human years – i.e., a Brahma lives for 311.4 trillion human years. After the death of each Brahma, there is a Mahapralaya or Cosmic deluge, when all the universe is destroyed. Then a new Brahma appears and creation starts all over again. 

(source: Am I a Hindu - by Ed Viswanathan  p. 292 - 293). For more on Yugas, refer to One Cosmic Day of Creator Brahma)

Time in Hindu mythology is conceived as a wheel turning through vast cycles of creation and destruction (pralaya), known as kalpa.  In the words of famous writer, Joseph Campbell:

"The Hindus with their grandiose Kalpas and their ideas of the divine power which is beyond all human category (male or female). Not so alien to the imagery of modern science that it could not have been put to acceptable use."

According to Guy Sorman, visiting scholar at Hoover Institution at Stanford and the leader of new liberalism in France: 

"Temporal notions in Europe were overturned by an India rooted in eternity. The Bible had been the yardstick for measuring time, but the infinitely vast time cycles of India suggested that the world was much older than anything the Bible spoke of. It seem as if the Indian mind was better prepared for the chronological mutations of Darwinian evolution and astrophysics."

Huston Smith a philosopher, most eloquent writer, world-famous religion scholar who practices Hatha Yoga.  Has taught at  MIT and is currently visiting professor at Univ. of California at Berkley. Smith has also produced PBS series. He has written various books,  The World's Religions,  "Science and Human Responsibility", and "The Religions of Man" says: 

“Philosophers tell us that the Indians were the first ones to conceive of a true infinite from which nothing is excluded. The West shied away from this notion. The West likes form, boundaries that distinguish and demarcate. The trouble is that boundaries also imprison – they restrict and confine.”  

“India saw this clearly and turned her face to that which has no boundary or whatever.” “India anchored her soul in the infinite seeing the things of the world as masks of the infinite assumes – there can be no end to these masks, of course. If they express a true infinity.” And It is here that India’s mind boggling variety links up to her infinite soul.” 

“India includes so much because her soul being infinite excludes nothing.” It goes without saying that the universe that India saw emerging from the infinite was stupendous.” 

While the West was still thinking, perhaps, of 6,000 years old universe – India was already envisioning ages and eons and galaxies as numerous as the sands of the Ganges. The Universe so vast that modern astronomy slips into its folds without a ripple.”

Dr. Carl Sagan in his book Broca's Brain: Reflections on the Romance of Science, remarks:

"Immanuel Velikovsky (the author of Earth in Upheaval) in his book Worlds in Collision, notes that the idea of four ancient ages terminated by catastrophe is common to Indian as well as to Western sacred writing. 

However, in the Bhagavad Gita and in the Vedas, widely divergent numbers of such ages, including an infinity of them, are given; but, more interesting, the duration of the ages between major catastrophes is specified as billions of years. .. "

"The idea that scientists or theologians, with our present still puny understanding of this vast and awesome cosmos, can comprehend the origins of the universe is only a little less silly than the idea that Mesopotamian astronomers of 3,000 years ago – from whom the ancient Hebrews borrowed, during the Babylonian captivity, the cosmological accounts in the first chapter of Genesis – could have understood the origins of the universe. We simply do not know.

The Hindu holy book, the Rig Veda (X:129), has a much more realistic view of the matter: 

“Who knows for certain? Who shall here declare it?
Whence was it born, whence came creation?
The gods are later than this world’s formation;
Who then can know the origins of the world?
None knows whence creation arose;
And whether he has or has not made it;
He who surveys it from the lofty skies,
Only he knows- or perhaps he knows not."

(source: Broca's Brain: Reflections on the Romance of Science - By Carl Sagan   p. 106 - 137).

The theory of animal life and particularly of man was correctly understood by the ancient thinkers. The Brihat Vishnu Purana states that "the aquatic life precedes the monkey life" and that "the monkey life is the precursor of the human life." The same theory was explained in an interesting way by the dashavatara (ten incarnations). But evolution, as everything else, was the manifestation of the supreme spirit (Atman) as is testified by Chandogya Upanishad.

wpe33.jpg (4159 bytes)Hinduism is the only religion that propounds the idea of life-cycles of the universe. It suggests that the universe undergoes an infinite number of deaths and rebirths. Hinduism, according to Carl Sagan, "... is the only religion in which the time scales correspond... to those of modern scientific cosmology. Its cycles run from our ordinary day and night to a day and night of the Brahma, 8.64 billion years long, longer than the age of the Earth or the Sun and about half the time since the Big Bang" 

Long before Aryabhata (6th century) came up with this awesome achievement, apparently there was a mythological angle to this as well -- it becomes clear when one looks at the following translation of Bhagavad Gita (part VIII, lines 16 and 17), 

"All the planets of the universe, from the most evolved to the most base, are places of suffering, where birth and death takes place. But for the soul that reaches my Kingdom, O son of Kunti, there is no more reincarnation. One day of Brahma is worth a thousand of the ages [yuga] known to humankind; as is each night." 

Thus each kalpa is worth one day in the life of Brahma, the God of creation. In other words, the four ages of the mahayuga must be repeated a thousand times to make a "day ot Brahma", a unit of time that is the equivalent of 4.32 billion human years, doubling which one gets 8.64 billion years for a Brahma day and night. This was later theorized (possibly independently) by Aryabhata in the 6th century. The cyclic nature of this analysis suggests a universe that is expanding to be followed by contraction... a cosmos without end. This, according to modern physicists is not an impossibility.

Count Maurice Maeterlinck (1862-1949) was a Belgian writer of poetry, a wide variety of essays. He won the 1911 Nobel Prize for literature. In his book Mountain Paths, says:

"he falls back upon the earliest and greatest of Revelations, those of the Sacred Books of India with a Cosmogony which no European conception has ever surpassed."

In Hindu thought, interspersed between linear, time-limited existences lie timeless intervals of non-existence. The creation hymn of the Hindus, Nasadiya-sukta of Rig-Veda, affirms an absolute beginning of things and describes the origin of the universe as being beyond the concepts of existence and non-existence 

“The Hindu ... pictured the universe as periodically expanding and contracting and gave the name Kalpa to the time span between the beginning and the end of one creation. The scale of this space or time is indeed staggering. It has taken more than two thousand years to come up again with a similar concept.” 

Hindu culture had this unique vision of the infiniteness of time as well as the infinity of space. When modern astronomy deals with billion of years, Hindu creation concepts deal with trillions of years. Vedanta upholds the idea that creation is timeless, having no beginning in time. Each creation and dissolution follows in sequence. The whole cosmos exists in two states -- the unmanifested or undifferentiated state and the manifested or differentiated state.

Princeton University’s Paul Steinhardt and Cambridge University’s Neil Turok, have recently developed The Cyclical Model. 

They have just fired their latest volley at that belief, saying there could be a timeless cycle of expansion and contraction. It’s an idea as old as Hinduism, updated for the 21st century. The theorists acknowledge that their cyclic concept draws upon religious and scientific ideas going back for millennia — echoing the "oscillating universe" model that was in vogue in the 1930s, as well as the Hindu belief that the universe has no beginning or end, but follows a cosmic cycle of creation and dissolution.

Dick Teresi ( ? ) author and coauthor of several books about science and technology, including The God Particle. He is cofounder of Omni magazine and has written:

"The big bang is the biggest-budget universe ever, with mind-boggling numbers to dazzle us – a technique pioneered by fifth-century A.D. Indian cosmologists, the first to estimate the age of the earth at more than 4 billion years. The cycle of creation and destruction continues forever, manifested in the Hindu deity Shiva, Lord of the Dance, who holds the drum that sounds the universe’s creation in his right hand and the flame that, billions of years later, will destroy the universe in his left. Meanwhile Brahma is but one of untold numbers of other gods dreaming their own universes.  The 8.64 billion years that mark a full day-and-night cycle in Brahma’s life is about half the modern estimate for the age of the universe. The ancient Hindus believed that each Brahma day and each Brahma night lasted a kalpa, 4.32 billion years, with 72,000 kalpas equaling a Brahma century, 311,040 billion years in all. That the Hindus could conceive of the universe in terms of billions."

The Hindus, according to Sir Monier-Williams, were Spinozists more than 2,000 years before the advent of Spinoza, and Darwinians many centuries before Darwin and Evolutionists many centuries before the doctrine of Evolution was accepted by scientists of the present age.

The French historian
Louis Jacolliot says,  "Here to mock are conceit, our apprehensions, and our despair, we may read what Manu said, perhaps 10,000 years before the birth of Christ about Evolution:
 
' The first germ of life was developed by water and heat.' (Book I, sloka 8,9 )
' Water ascends towards the sky in vapors; from the sun it descends in rain, from the rains are born the plants, and from the plants, animals.'  (Book III, sloka 76).

Sir John Woodroffe, (1865-1936) the well known scholar, Advocate-General of Bengal and sometime Legal Member of the Government of India. He served with competence for eighteen years and in 1915 officiated as Chief Justice. He has said: 

"Ages before Lamarck and Darwin it was held in India that man has passed through 84 lakhs (8,400,000) of birth as plants, animals, as an "inferior species of man" and then as the ancestor of the developed type existing to-day. 

"The theory was not, like modern doctrine of evolution, based wholly on observation and a scientific enquiry into fact but was a rather (as some other matters) an act of brilliant intuition in which observation may also have had some part."

Thus, in Hinduism, science and religion are not opposed fundamentally, as they often seem to be in the West, but are seen as parts of the same great search for truth and enlightenment that inspired the sages of Hinduism. Fundamental to Hindu concept of time and space is the notion that the external world is a product of the creative play of Maya (illusion).

To the philosophers of India, however, Relativity is no new discovery, just as the concept of light years is no matter for astonishment to people used to thinking of time in millions of kalpas, 

***

"To the philosophers of India, however, Relativity is no new discovery, just as the concept of light years is no matter for astonishment to people used to thinking of time in millions of kalpas, (A kalpa is about 4,320,000 years). The fact that the wise men of India have not been concerned with technological applications of this knowledge arises from the circumstance that technology is but one of innumerable ways of applying it."

It is, indeed, a remarkable circumstance that when Western civilization discovers Relativity it applies it to the manufacture of atom-bombs, whereas Oriental civilization applies it to the development of new states of consciousness."

The late scientist, Carl Sagan, asserts that the Dance of Nataraja (Tandava) signifies the cycle of evolution and destruction of the cosmic universe (Big Bang Theory). According to Carl Sagan, (1934-1996) astro-physicist, in his book Cosmos says:

"The Hindu religion  is the only one of the world's great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths. It is the only religion in which the time scales correspond, to those of modern scientific cosmology. 

 "It is the clearest image of the activity of God which any art or religion can boast of." Modern physics has shown that the rhythm of creation and destruction is not only manifest in the turn of the seasons and in the birth and death of all living creatures, but also the very essence of inorganic matter.

 For modern physicists, then, Shiva's dance is the dance of subatomic matter. Hundreds of years ago, Indian artist created visual images of dancing Shiva's in a beautiful series of bronzes. Today, physicist have used the most advanced technology to portray the pattern of the cosmic dance. Thus, the metaphor of the cosmic dance unifies, ancient religious art and modern physics. 

"The Hindu religion  is the only one of the world's great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths. It is the only religion in which the time scales correspond, to those of modern scientific cosmology.  Its cycles run from our ordinary day and night to a day and night of Brahma, 8.64 billion years long. Longer than the age of the Earth or the Sun and about half the time since the Big Bang.  And there are much longer time scales still."

Fritjof Capra (1939 - ) Austrian-born famous theoretical high-energy physicist and ecologist wrote:

"Modern physics has thus revealed that every subatomic particle not only performs an energy dance, but also is an energy dance; a pulsating process of creation and destruction. The dance of Shiva is the dancing universe, the ceaseless flow of energy going through an infinite variety of patterns that melt into one another’’. For the modern physicists, then Shiva’s dance is the dance of subatomic matter. As in Hindu mythology, it is a continual dance of creation and destruction involving the whole cosmos; the basis of all existence and of all natural phenomenon. Hundreds of years ago, Indian artists created visual images of dancing Shivas in a beautiful series of bronzes. In our times, physicists have used the most advanced technology to portray the patterns of the cosmic dance."

Nancy Wilson Ross (1901 -1986) made her first trip to Japan, China, Korea and India in 1939. She was the author of several books including The World of Zen and Time's Left Corner. Miss Ross lectured on Zen Buddhism at the Jungian Institute in Zurich. She served on the board of the Asia Society of New York which was founded by John D. Rockefeller III since its founding in 1956 and was on the governing board of the India Council. In private life she was known as Mrs. Stanley Young.

She has written:

"Anachronistic as this labyrinthine mythology may appear to the foreign mind, many of India’s ancient theories about the universe are startlingly modern in scope and worthy of a people who are credited with the invention of the zero, as well as algebra and its application of astronomy and geometry; a people who so carefully observed the heavens that, in the opinion of Monier-Williams, they determined the moon’s synodical revolution much more correctly than the Greeks."

" Many hundreds of years before those great European pioneers, Galileo and Copernicus, had to pay heavy prices in ridicule and excommunication for their daring theories, a section of the Vedas known as the Brahmanas contained this astounding statement: 

“The sun never sets or rises. When people think the sun is setting, he only changes about after reaching the end of the day and makes night below and day to what is on the other side. Then, when people think he rises in the morning, he only shifts himself about after reaching the end of the day night, and makes day below and night to what is on the other side. In truth, he does not see at all.” 

"The Indians, whose theory of time, is not linear like ours – that is, not proceeding consecutively from past to present to future – have always been able to accept, seemingly without anxiety, the notion of an alternately expanding and contracting universe, an idea recently advanced by certain Western scientists. In Hindu cosmology, immutable Brahman, at fixed intervals, draws back into his beginningless, endless Being the whole substance of the living world. There then takes place the long “sleep” of Brahaman from which, in course of countless aeons, there is an awakening, and another universe or “dream” emerges. "

"This notion of the sleeping and waking, or contracting and expanding, of the Life Force, so long a part of Hindu cosmology, has recently been expressed in relevant terms in an article written for a British scientific journal by Professor Fred Hoyle, Britain’s foremost astronomer. "

"Plainly, contemporary Western science’s description of an astronomical universe of such vast magnitude that distances must be measured in terms as abstract as light-years is not new to Hinduism whose wise men, millennia ago, came up with the term kalpa to signify the inconceivable duration of the period elapsing between the beginning and end of a world system.  

"It is clear that Indian religious cosmology is sharply at variance with that inherited by Western peoples from the Semites. On the highest level, when stripped of mythological embroidery, Hinduism’s conceptions of space, time and multiple universes approximate in range and abstraction the most advanced scientific thought. "

Dr. Heinrich Zimmer (1890-1943), the great German Indologist, a man of penetrating intellect, the keenest esthetic sensibility observed:

“In one of the Puranic accounts of the deeds of Vishnu in his Boar Incarnation or Avatar, occurs a casual reference to the cyclic recurrence of the great moments of myth. The Boar, carrying on his arm the goddess Earth whom he is in the act of rescuing from the depths of the sea, passingly remarks to her: 

“Every time I carry you this way….” 

For the Western mind, which believes in single, epoch-making, historical events (such as, for instance, the coming of Christ) this casual comment of the ageless god has a gently minimizing, annihilating effect."

Professor Arthur Holmes (1895-1965) geologist, professor at the University of Durham. He writes regarding the age of the earth in his great book, The Age of Earth (1913) as follows:

"Long before it became a scientific aspiration to estimate the age of the earth, many elaborate systems of the world chronology had been devised by the sages of antiquity. The most remarkable of these occult time-scales is that of the ancient Hindus, whose astonishing concept of the Earth's duration has been traced back to Manusmriti, a sacred book."

When the Hindu calculation of the present age of the earth and the expanding universe could make Professor Holmes so astonished, the precision with which the Hindu calculation regarding the age of the entire Universe was made would make any man spellbound.

(source: Hinduism and Scientific Quest - By T. R. R. Iyengar p. 20-21).

The Upanishads developed this spirit of inquiry, and traces of naturalistic and scientific thought in them are quite significant. The Samkhya system, which has been described as the ruling philosophy of pre-Buddhist India and an orthodox system having its roots in the Upanishads, is essentially rational, anti-theistic, and intellectual. According to Richard Garbe, it was in Samkhya doctrine that complete independence and freedom of the human mind was exhibited for the first time in history. Samkhya, probably the oldest Indian philosophical system, furnished the background for the Yoga system, and the early Buddhist biography Lalitavistara includes both Samkhya and Yoga in the curriculum of study for the young Buddha. Samkhya is generally ascribed to Sage Kapila and Yoga to Sage Patanjali. Ideas of natural selection, atomic polarity and evolution. 

Like in other ancient civilizations, in Hindu India priests and scientists were often the same persons; the conflict between religion and reason is not the primitive condition but a contingent historical development in post-classical Europe, paralleled to an extent by the stagnation of Muslim culture from the 12th century onwards. The Sankya philosophy of Kapila, in short, is devoted entirely to the systematic, logical, and scientific explanation of the process of cosmic evolution from that primordial Prakriti, or eternal Energy. There is no ancient philosophy in the world which was not indebted to the sankhya system of Kapila. The idea of evolution which the ancient Greeks and neo-Platonists had can be traced back to the influence of this Sankhya school of thought.

Professor Edward Washburn Hopkins (1857-1932)  Indologist, Chair of Sanskrit Studies of Yale, says:

"Plato is full of Sankhyan thought, worked out by him, but taken from Pythagoras. Before the sixth century B.C. all the religious-philosophical idea of Pythagoras are current in India (L. Schroeder, Pythagoras). If there were but one or two of these cases, they might be set aside as accidental coincidences, but such coincidences are too numerous to be the result of change. "

And again he writes: "Neo-Platonism and Christian Gnosticism owe much to India. The Gnostic ideas in regard to a plurality of heavens and spiritual worlds go back directly to Hindu sources. Soul and light are one in the Sankhyan system, before they became so in Greece, and when they appear united in Greece it is by means of the thought which is borrowed from India. The famous three qualities of the Sankhyan reappear as the Gnostic 'three classes.'

(source: Religions of India - By Edward Washburn Hopkins   p. 559-560).

Some sources even credit Pythagoras with having traveled as far as India in search of knowledge, which may explain some of the close parallels between Indian and Pythagorean philosophy and religion. These parallels include: 

  1. a belief in the transmigration of souls;
  2. the theory of four elements constituting matter;
  3. the reasons for not eating beans;
  4.  the structure of the religio-philosophical character of the Pythagorean fraternity, which resembled Buddhist monastic orders; and
  5. the contents of the mystical speculations of the Pythagorean schools, which bear a striking resemblance of the Hindu Upanishads

According to Greek tradition, Pythagoras, Thales, Empedocles, Anaxagoras, Democritus and others undertook journey to the East to study philosophy and science. By the time Ptolmaic Egypt and Rome’s Eastern empire had established themselves just before the beginning of the Common era, Indian civilization was already well developed, having founded three great religions – Hinduism, Buddhism and Jainism – and expressed in writing some subtle currents of religious thought and speculation as well as fundamental theories in science and medicine.

A 9th century Hindu scripture, The Mahapurana by Jinasena claims the something as modern as the following: (translation from [5])

"Some foolish men declare that a Creator made the world. The doctrine that the world was created is ill-advised, and should be rejected. If God created the world, where was he before creation?... How could God have made the world without any raw material? If you say He made this first, and then the world, you are faced with an endless regression... Know that the world is uncreated, as time itself is, without beginning and end. And it is based on principles."

Modern people divide the day into 24 hours, the hour - into 60 minutes, the minute - into 60 seconds. Ancient Hindus divided the day in 60 periods, lasting 24 minutes each, and so on and so forth. The shortest time period of ancient Hindus made up one-three-hundred-millionth of a second.

Speed of Light: 

Sayana (c. 1315-1387) was a minister in the court of King Bukka I of the Vijayanagar Empire in South India; he was also a great Vedic scholar who wrote extensive commentaries on several ancient texts. In his commentary on the fourth verse of the hymn 1.50 of the Rig Veda on the sun, he says:

Tatha cha smaryate yojananam sahasre dve dve shate dve cha yogane ekena nimishardhena kramamana namo ‘stu ta iti   

Thus it is remembered: (O Sun), bow to you, you who travers 2,202 yojanas in half a minute. 

The Puranas define 1 nimesha to be equal to 16/75 seconds. 1 yojana is about 9 miles. Substituting in Sayana’s statement we get 186,000 per second.  

Sayana’s statement was printed in 1890 in the famous edition of Rig Veda edited by Max Muller, the German Sanskritist . He claimed to have used several three or four hundred year old manuscripts of Sayana’s commentary, written much before the time of  Romer. Further support for the genuineness of the figure in the ancient book comes from one of the earliest Puranas, the Vayu, conservatively dated to at least 1,500 years old. The Puranas speak of the creation and destruction of the universe in cycles of 8.64 billion years, that is quite close to currently accepted value regarding the time of the big bang.

Physics

In the realm of physics, remarkable contributions have been made by Indian scientists. Some hint at the theory may be contained in the views of Uddalaka Aruni, preserved in the Chandogya Upanishad. Uddalaka says: "matter was at first a chaotic mass, like the juices of various trees indiscriminately blended together in honey. In order to develop names-and-forms, to discriminate things from one another, or to set them in order, the universal spirit came not in its universal form but as the living, principle, and entered into Fire, Water and Earth. After separating their component but qualitatively distinct parts (dhatus), it made numerous new combinations of them. By propounding the theory of combination and separation of particles, Uddalaka anticipated the atomic theory of Kannada.'

Kanaada, the founder of the Vaisesika system of philosophy, expounded that the entire matter in this world consists of atoms as many in kind as the various elements. Kanaada's atom would then correspond to the modern atom. He said:

 "The cause of creative motion is believed to be adrsta, unseen moral force which guides the destiny of souls according to their karma and requires them to be provided with properly equipped bodies and an appropriate objective world for the experience of pleasure and pain. It is due to the operation of this metempirical force that atoms start moving to get together in order that they may be integrated into countless varieties of things."

Some Jain thinkers went a step further. They thought that all atoms are the same kind and variety emerged because they entered into different combinations. Kanaada taught that light and heat are variations of the same reality. 

Vacaspati interpreted light as composed of minute particles emitted by substances and striking the eyes. This is a clear anticipation of the corpuscular theory of light, which was proposed by Newton but rejected till the discovery of the proton.

Modern physics confirmed that the sun's rays travel in a curved way, but not in a straight line. Our ancestors told that the sun's chariot was drawn by seven horses tied by snakes. As the movements of the snakes are crooked and curved, so also the sun's ray. The phenomenon is described in a metaphysical poetic line bhujagana mita sapta turaga. The chapter on light says that there are seven colors in the white ray of the sun. Artharveda says that there are seven types of sun's rays, sapta surayasya rasmayah. 

The law of gravitation discovered by Brahmagupta anticipated Newton by declaring "all things fall to the earth by law of nature; for it is the nature of the earth to attract and keep things."

Kannada was an expounder of the law of causation and of the atomic theory. He classified all the objects of creation into nine elements, namely: earth, water, light, wind, ether, time, space, mind and soul. According to his theory every object of creation is made of atoms, which in turn are joined with each other to form molecules. His statement ushered in the Atomic theory for the first time in the world, early 2500 years before John Dalton. Kanaada has also described the dimension and motion of atoms and their chemical reactions with each other. 

T. N. Colebrooke, has said: "Compared to the scientists of Europe, Kanaada and others Indian scientists were the global masters in this field."

(source: Calendar 2002 - VHP of America).

Umasvati, who lived in the first century A.D. suggested that atoms of opposite qualities alone combined and the atoms attracted or repelled as they were heterogeneous or homogenous. Commenting on these theories, A. L Basham remarks: "Indian atomic theories were not of course, based on experiment, but on intuition and logic..."

Gravity was considered a peculiar cause of primary descent or falling...In the absence of counter-balancing cause, as adhesion, velocity or some act of volition, descent results from this quality. Thus a coconut is withheld from falling by adhesion of the foot-stalk, but this impediment ceasing on maturity of the fruit, it falls. The penetrative diffusion of liquid was explained by capillary motion and the conduction of water in pipes was said to be due to the pressure of air. They were familiar with an accurate method of calculating velocity which facilitated the measurement of the relative pitch of musical tones with great precision. They anticipated the Pythagorean law of vibration of stretched strings. viz. the number of vibrations varies inversely as the length of the string.

The believed that energy was indestructible and thus anticipated the law of conservation and e
