Cosmic Ocean...

(Milky Way - our galaxy)

Our universe consists of many billions of galaxies. “Milky Way” alias Cosmic Ocean is one such galaxy where our earth, moon and the entire solar system consisting of all planets and billions of stars including the Sun are located. There are further billions of galaxies unknown to the astronomers! Each such galaxy contains billions of stars like in Milky Way.

Our Milky Way galaxy takes the shape of a “Conch shell”. There are cyclical involutions at the center point of the galaxy similar to the conch shell. The outer portion of the galaxy looks like a flat disc (chakram). Hence this galaxy is also known as Spiral Galaxy.

Sun is the embodiment of Sudarsana Chakram which is believed to give light equivalent to millions of suns. Sanghu (conch) is denoted by moon. Lord Krishna is “Shanghu-chakra dhaari” (One who holds the Chakram and Shanghu).

"சங்கொடு சக்கரமேந்தும் தடக்கய்யன்"

Sanghu is dearest to Lord Krishna as it never gets separated from him and it also enjoys the privilege of touching the beautiful lips of lord any time he blows. Sanghu produces sound for victory and its vibration will remove our ignorance. (It is believed that Lord Krishna resides in Milky Ocean or Thirupparkadal)

The universe is like a golden egg. Our Milky Way galaxy seen above is in the center of the universe. The shape of the Universe in oval shaped egg was first brought to the notice of the astronomers by the release of ever first image of entire universe by European Space Agency (ESA). Plank, the space telescope sent last year in to the sky returned with images which were assembled by ESA to give incredible images of our Universe.

As per Sri Vaishnavism, Lord Vishnu creates preserves and destroys it finally. Similar to a spider which spits from its mouth viscous liquid to create a web net around it and finally takes it back in to its stomach, Lord Vishnu after pralayam swallows the entire universe and keeps it in his stomach.

OM is the most often chanted sound among all the sacred sounds on earth. This sound is considered as the sound of the existence. It is believed that the whole universe, in its fundamental form, is made up of vibrating, pulsating energy. Om is considered as the humming sound of this cosmic energy.

OM is the sound which is not the result of the striking of two objects. It rather emanates on its own. It is the primal sound of the universe that contains all sounds in itself. This sound of OM produces instant positive vibrations and takes the listener to a state of mental stillness.

Lightning Strikes...

Lightning - "An atmospheric discharge of electricity accompanied by thunder, which typically occurs during thunderstorms, and sometimes during volcanic eruptions or dust storms " as defined by Wikipedia. But that is not the only way I would describe lightning.

Like how every natural phenomenon like rain or sunshine is essential, lightning is also essential. When the annual rainfall decreases, it affects this ecosystem one way or the other, likewise, if no lightning occurs, this planet may have to face several consequences.

I would say, this natural phenomenon is so lovely, as tremendous energy is imparted to the earth during the process. It is estimated that, with the energy liberated with just one stroke of lightning, the entire city of Chennai could be guaranteed free power supply for a month. Surprising right? It is true!

So the next question is, why do we not use this form of energy to produce electrical energy for household and various other engineering fields. The answer is simple. It is because it is just not possible to trap that enormous amount of energy.

As the air molecules breakdown due to excess potential difference, it is not possible to transfer or even store energy in form of voltages beyond a limit. Thus, it becomes absolutely impossible to obtain energy from lightning. This could be held as the reason for the Van de Graff generators to be placed in Nitrogen atmosphere. Nitrogen gas has got a high capacity to withstand potential difference. (Implicitly it means Nitrogen has a very high dielectric constant).

We in fact create a mini form of lightning everyday in our house and workplaces. Whenever we switch on a switch; the distance between 2 parallel plates of a capacitor becomes smaller and smaller, thereby increasing the potential difference. At the point when the breakdown potential (of air) is reached, there is a small spark created which is then neutralized. In other words, the mega form of spark is a lightning.

Without lightning, the nitrogen would not be available for plants and hence the humans.

The "kodimaram" in hindu temples is constructed having the science of lightning in mind. It has sharp edges here and there. Thus, due to the action of sharp points, it can store and also spray a good amount of energy all around (CORONA DISCHARGE). That is why, temples are constructed with tall and huge 'gopurams' and 'kodimaram'.

The energy I refer to here is not the electric energy, but a form of energy vibrations that is not known to many. It is the vedic energy. The chanting of vedas transforms the sound energy to vedic energy. Thus as more number of people chant the vedas coherantly, there is a constructive interference of all sound waves and hence a greater amount of sound energy is transformed to vedic energy (I use the word transform because, energy can only be transformed not created or destroyed).

The famous tamil word "Goshti" (Group)refers to this. I do not talk about the "Goshti Poosal" in State and Central Houses of the Government. It was a holy and a great practice of our fore fathers to participate in the Goshti especially during the festivals in temples. There is a place called 'Thirukkoshtiyur' near Madurai. It is said that the rishis assembled in a Goshti to sing in praise of Krishna in that place, and hence came to be known as 'Koshti'yur.

The energy I have been mentioning about so far is the positive form of energy. It is very easy to obtain this form of energy. All we need to do is to keep our souls fresh and peaceful. We always need to think about good aspects of life. We must restrain ourselves from abusing or complaining about others. Also, we must not stay idle (Idle mind is devil's workshop). To gain more and more positive energy into ourselves, it is just enough that we stay positive all the time!!!

What Nano Technology taught me……………!

This is my first ever post in these ‘blogs’. So I am not a professional or an expert in writing blogs.…Why I say that at first is, you can just close this window if you feel that this useless fellow has no other job than writing some ‘idiotic’ and ‘senseless’ blogs or in short a ‘mokkai’... J So I warn friends! Please do close this window if you feel so!

So that’s the introduction, as to what I am gonna discuss here. But I repeat! Please do close this window if you feel so, right now. And I also do not want you to say “I have really wasted time reading your blog!”. But please note that I am not going to discuss the engineering part of it.. So then it must be interesting only…:P

Fine… So that’s ok… I can get into my topic now… So the topic says ‘What nano technology taught me’. So then it’s my duty to first define what nano technology is… The term ‘nano technology’ is a little abrupt term. Why I call that abrupt is, the words do not convey the full meaning, as any teacher would expect precise answer from students.

The word is just like the word ‘Oorugai’. Does the word ‘Oorugai’ convey full meaning to you? No right??.. Because, is it “Oorina Kai” or “Oorugindra Kai’ or “Oorapogum Kai”. Similarly, the word Nano technology can be taken in these ways – Is it the technology of making products of nano scale??? Then how are we going to handle such small particles… So the catch is we are gng to produce items with nano particles to make the product with better properties and features.

So that’s the definition part of it. And its study is important because many natural forms are only in nano scale... What about the human cells…. They are in nano scale and its malfunctioning can lead to various diseases.

The concept of nano technology is also well discussed in Indian literature part… especially in Tamil…i.e. “Kanninun Siruthambinal kattunnappanniya perumayan” Lord Krishna was tied to a pillar by Yasoda. He increased his belly size and all ropes got detached. Thus Yasoda was highly troubled and she wanted to cry in front of Krishna so that he could understand her plight. After having seen that, Krishna allowed himself to get tied, but to a special rope which is “Kanninun Siruthambu” i.e. a very small rope with very little knots. So that’s just to tell how Krishna was tied to a nano rope… Interesting right?? Am happy J

All that’s okay.. But the topic is “What nano technology taught me” And I have not touched even a bit on that! Having said all this, I must quickly come to the point… The above paragraphs s just like adding water for preparation of noodles….Yet to use masala to make it tastier… So ill start….

As said earlier, nano particles, are particles of the nano scale, used to prepare products of great properties and characteristics.…. Thus, the nano particles are of such small sizes and can perform wonders! Yes!!!!! WONDERS!! They can turn ‘colourless’ objects into colourfull substances! They can covert fuel to a poison, render an inedible substance edible, replace a pungent odour with a fragnant one and so on…. Such small particles having great consequences!! And I want you to realize that, and appreciate all that is said above! I mean about nano particles and not my words! After all...they are ordinary words and my words are not energetic and sufficient enough to completely appreciate them! So assume that I have not even shown you a drop from the ocean! The rest is up to you to imagine…..

All right…. So then, what was taught to me by Nano technology???? -And another point here… All poets personify various things to show their skill in writing poems….But now that I have said “What nano technology has taught me”, does it mean I am giving it human qualities, and I am making it speak and teach me??? So does it mean I am a good poet?? No way!!! So then, I should have put the title as “What I learnt from Nano technology” right…? Thought about that for a while and again changed the title back. Why??? Because of the occurrence of the letter “I” in that. Never should one think “I did it, it was all possible because of me etc…” They are dangerous statements capable of pushing one to the most pathetic position that the person would have not even imagined. So the moral here is that it was not me who learnt from Nano technology, but the other way round….

The first thing I was told was, “Never think things that are small are ineffective” I have seen people in ma life who are extremely intelligent and loaded with stuffs to the maximum possible extent and are short”. Here the adjective ‘short’ is just one among the adjectives used. The shortness is definitely not a cause for concern.

“Moorthy sirusa ka irunthalum Keerthy Perusu” goes a tamil saying! Meaning, the moorthy is small i.e. the figure being talked about and keerthy refers to the knowledge. Just appreciate the saying as to how it supports the very concept of Nano Technology! J And that’s why I really respect tamilians. Their various sayings have a brilliant scientific background! Another example is the saying “Pon kidaithalum, Bhutan Kidaikkathu!”. “Pon” is gold! Gold was a rarity in those days! And that’s why they lead a happy life! They were never greedy of money and gold… But time has changed and now we see lots of ‘greedy’ people shopping in “Thanga Maligai” under the false belief that buying gold on “Akshay Trithya” day, will result in down pouring of gold coins from the ceiling! Never shall it happen! The least thing that can happen is the complete failure of foundation and collapse of ceiling! There were great mahans who led a peaceful life without a penny in their hand! Continuing with the explanation for the saying, we are left with the other part – “Bhutan Kidaikkathu”. “Bhutan” here does not refer to Wednesday! It refers to the planet “Mercury”. So the complete essence of the saying is that “It is even possible to get gold, but not mercury!” I am fond of this particular saying as it establishes the fact that it is impossible to spot Mercury, the planet with naked Eyes!” Tamilians had discovered this particular fact long back even before NASA scientists could do! This accounts for their immense knowledge in Astro-physics!

The second thing is “Uyarvu enbathu manathil iruppathu, Udalil iruppathalla!” Meaning, we need to be a taller person, not wrt to height, but wrt our qualities! A tall person with no good qualities is just like an animal that knows nothing! You can call a person tall if he is bestowed with all good qualities!

So that’s it with this particular blog! I shall definitely try to make a better one next time! Please feed in your comments…….!
