Atmosphere of Earth by Pandit Gurudutta Vidyarthi M.A.
Layer of Atmosphere

There is nothing which so beautifully illustrates the bounteous dispensation or providence in Nature, as the atmosphere, which surrounds our earth to a certain height all rounds. This gaseous envelope, which is elasty and at the same time so rare, is especially characterized by its lightness, which renders it amenable to the influence of disturbances even the slightest. Airship Science in the Vedas .
Imagine a huge mass or iron lying inert, say in one position, and suppose a heavy stone or a dense ball dashed against this grotesque ball of iron, and see what follows. You will see how sluggishly the grotesque mass obeys the impulse, how reluctantly, as it were, the idle mass parts with its inert condition to be alive with the activity of the impinging stone ! what vide contrast does the atmosphere present to this inert mass. Each molecule of the air, on account of its lightness and elasticity, so readily succumbs to all forces from without, so mechanically multiplies, the impulse, as it were, by its mobility, that even the slightest tremor first communicated to it sends it dashing along the free path or molecules in air, until it meets a fresh encounter with another molecule. This molecule, like a waiting position, immediately stands up and proceeds on its errand. The next molecule obeys the first and the third obeys the 2nd and so on. Only a few moments elapse, in the (twinkling of an eye, when a vast tract in the expansive ocean of air-a tract of almost a mile in area, 5 times 1,100 feet long,–is furrowed over with ripples of exquisite beauty. Just imagine how sensively delicate the molecules or air must be, There is not a faint flutter of wings, not a noiseless breath that ever escapes and does not furrow tracts of air with equisite waves.
Tremors are thus communicated with gigantic velocity by this mobile air. The invisible artistic designs into which the molecules of air thus cast, are only beautiful beyond description. A genuine transcript of the true state of things are the word of poet Emerson. Ancient Telegraphy Science in the Vedas.
“Thou canst not wave thy staff in air,
Or dip the paddle in the lake.
But it craves the brow of beauty there,
And the ripples in rhymes the oars forsake.”
It is one the mobile wings of air that the fragrance of flowers, the odour of essences and the effluvia of substances are wafted to immense distances creating a diffusiveness that blends motion into uniformity and harmony. Is not, then, a light, mobile, tremor-communicuting, effluvia-carrying medium a better and a more exact appellation for this masterly creation of the Architect of Nature than the ugly, unmeaning, inexact and half-articulate word air. It is exactly this sense, italicized in the above lines, which the Vedic word vayu conveys, the word with which the mantra quotes above beings. Birth of Gold and Minerals in the Vedas.
We have seen what the physical properties of the molecules, which compose the air, are. Let us now consider the phenomena which it gives rise to. The rays of the sunf falling upon the earth hear the layers of earth. Which in their turn heat the layers of air in contract with them. These layers of air, when heated, become lighter and ascend. Colder layer of air rush in to fill up the vacumm created by the ascending hot layersm they heated in their turn, similar layers of air. Thus a rapid circulation of hear goes on, which gives rise to currents. Of exactly similar nature are all the winds that blow. From the same cause originate those north-eastern, south-eatern winds known as trade-winds. The protions of earth near the equator always receive a greater quantity of heat form the sum than others do. The layers of air in contract with those protions of earth rise, and colder air from northern and southern quarters rushes in tomotions of earth, gives rise to north-eastern and south-eastern winds. Firstly, then, we find that the air is always circulating and giving rise to currents in perpetual motion. This vayu, then, is always moving in the form of currents.
Next, see what effect it has in modifying the phenomena of light. The rays of light, which traverse through solar and interplanetary regions, ultimately strike upon the highly-rarefied layers of air, high above in the skies. In passing from vacuum into air, these rays of light deviate in their course, and pursue a bent direction on account of refraction. Had the lower rays or air, through which these rays have to pass, been of uniform temperature, once having bent in its course in contact with have then pursued its course undeviated in air. But meeting with layers of air of different temperatures and, therefore, of different densities, it is, at each step that it advances a little refracted again and again so that these rays, having passed through all curious path, all zigzag ways that it is possible to imagine, ultimately meet terrestrial objects, including the eyes of man, and there excite vision. Ancient Biology Science in the Vedas.
How wonderfully it modifies and extends the range of vision, will then be apparent. Even the most delusive appearance known as “the mirage” that is often seen by travelers in the hot sandy deserts, is dur to the reflection and refraction of light at innumerable surfaces presented by the heated layers of air. It is through air, then, that we are able to see not Only in the direction of the source of light, the sun, but in all other possible directions. It is also dur to air that such delusive phenomena or appearances as the mirage start into vision. Our atmosphere, then, besiders giving rise to currents, extends the range of our vision and is the cause of the phenomena like that of mirage. Hence it is, that we have, in the Vedic mantra quoted above, the word darshata, the cause of extension of vision and of other appearances. Human Brain Science in Vedas.
Another and a very important part which the air playes in the economy of nature is the purpose it serves of the maintenance of vegetable world. Always there is a certain quantity of carbonic acid present in the air, which how ever slight, is sufficient to maintain the equilibrium between the animal and the vegetable worlds. The trees and plants, the main body of which essentially consists of carbon, derive all their carbon from the air. The leaves of plants possess a kind of substance called chlorophyll, which in the presence of light decomposes the carbonic acid gas present in the air. The carbon which results from this decomposition is assimilated by the plants, and the oxygen is set free. This oxygen, freed from carbonic acid, so to say is what animal inspire. Animal life is maintained by the continuance of animal heat, which is dur to the combustion of oxygen with carbon of the animal frame. The Galaxay in the Vedas.
Thus all animals inhale oxygen and exhale carbonic acid, whereas all plants absorb carbon of the carbonic acid. Air thud stands a common vehicle between the vegetable and the animal kingdoms. Due to these causes, all plants and animal life depends upon the presence of air. Not only is air necessary for the existence of plants and animals, but is also necessary for the maintenance of dynamical equilibrium between these two classes or organic nature. The word soma used in the Vedas means something that springs out of breathm and especially designates the vegetable kingdom which as such, is necessarily dependent upon the soil from which it springs. Hence we have soma arankritah tesham pahi in the Vedic mantra, meaning thereby that the atmosphere preserves the equilibrium between the vegetables and the animal kingdoms.
Another fact worth noticing in discussing the phenomena of air, is that it is the vehicle of all sounds, man has been often called speaking animal; and, no doubt, the capacity of speech distinguishes man to a very great extent from other members of the animal kingdom. Now this speech, which, in this sense, is at the root of our advancement and civilization, essentially consists of articulated sounds, the utility of which would have been entirely marred, if there had been no air. Air, then, is also a vehicle of sound, a fact which is mentioned in the mantra in the last two words, shrudhi havam-it makes our sounds and all others’ as well heard. Agriculture Science in the Vedas.
