Revisiting nano robots!/ or Photonic crystals! or entirelt diff Motivation?

Now I have so much in mind that I wanna put everything here. my fever and head ache is so severe that I cant stand sit or sleep! So thoguht of slowly writing a big post defining nano robots ( it may seem todays fiction but tommorow's reality. ) and their uses. I am always bothered about biological (medical?) usage.

Nano Robots : First any particle which is very small is nanoparticle. Now if you ask small. then the answer will be a question like this : " How Small? " Heres the answer : When the particle size is comparable to the Bohr exciton radius ( some value unique to each material ) then you find classical mechanics obsolete. There comes Quantum Mechanics. all are Quantum effects. Now the particles are confined to a smaller region ( about the order of few Bhor exciton radiuses ) Then each particle with fewer atoms acts as as indivdual. Now they wont interact ordinarly. For example nano particle paints, there will not be any dust on it. Just it expuls everything. so no ned of cleaning the walls for festivals or repainting it just dust it with a cloth. Then the nano robots in my last post on nanorobots I said that it should have a computing power. Then chemical computer is the best. Beacuse what happens in our body is just nothing but a few not few exactly many chemical reactions or some some ion imbalance. For example when we want to move our hand our brain sends a signal through. So now the signal is just simply a change in the Na/K( Sodium/Pottasium ) concentration. Now in the same way when our nano robot interacts with the pathogen it should sense that its a pathogen and simply destroys some or the other thing( like protein or RNA. primitive organisms have RNA rather than DNA or both. ). There should be a mechanism ( suggested by my friend Sasikanth ) a control sytem like where all the nano robots communicate with each other so that they dont attack the same and also they should self destroy after certain amount of time without poisoning the body. This makes it very very complex to make it pathogen specific. But time gives the solution and I remember this statement : " world is so fast that there are days when the person who says it can't be done is interrupted by the person who is doing it.. " Three cheers to Material Science and Biophysics!

Phoonic Crystals : What if you have a TeraHertz powered PC? wow....Thrilling to even think. But soon its going to be a reality. Whats at the heart of such a PC? Its this the OPTICAL PROCESSOR! Normal electrical processor is limited by the speed of electrons. But light has the Ultimate speed. So the faster is the communication and more is the bandwidth. A simle optical processor is a lens. Just put some light(signal form) on a lens what we get on other side is its Fourier transform.( Anybody who knows fourier optics can realise it. )As simple as that. Where to calculate a fourier transform sometimes a very tedious calculation of integrals is required. Ineterestin and Exciting to hear. But very difficult to fabricate such a thing. We have all logic gates and everything but the problem is how to generate light & guide light( simultaneously ) in such small space. Solution is photonic crsytal. To define it first whats a crystal? Any periodic arrangement. Simply the samething. periodic arrangement of two dielectric materials with diff refractive indices. Now create a microcavity. They simply give a lasing action and generates light. Then by creating some defects in the photonic crystal it simply directs the light in the required diretion. A 2D photonic crystal is easy to build. But real problem maintainf such an accuracy in a 3D crystal. here I end beacuse this too techy & lot of stuff is not clear( Though I wanna expalin each and every term then It would be a big book. )

Motivation : Motivation is a very important chapter in Psychology. Its not only important in textbooks but also its very important factor in your life. After seeing this movie " Swarnakamalam " Venky and Banupriya starrer. In that what happens is BanuPriya hates Bharatanatyam but because of his father's pressure she has to learn it. Simply she hates to dance. Once a big dancer comes and offers her to take to USofA. Then this motivates her to dance. Then she dances and finds it as a passion. What happens is when work for something( motivated by some goal ) after you are involved into it the passion drives. I will make another post on motivation. Do come back soon.

Another test of patience!

Today I uploaded 138 photos 138 thumbnails 138 html pages and some files on the occasion of Asif bday. Woh my gaurd it took more than 2 hours time continuously doing the same thing choosing the file upload. uffff.....

Hey Asif's Brithday....

Me Asif & Thulasi!
Today is our loving pra'asif' birthday. Many Many Happy Returns of The Day Dude!
