Don't try Indians patiece

When I have seen the movie "Rang de basanti".. uska end dekh k mujhe laga tha k kisi bhi chiz ko leke hamari county k log iss tarah se jagrit ho k nahi ladenge..par I am really very much socked k aaj hamara pura desh ak ho k Brastachar k khilaf ki iss ladai me Anna ji k sath he.. sahi me hats of to Anna ji k unhone pure desh ko ak dhage me bandh lia he.. jahan koi alag nahi he.. har dharm k, har jati k har tarah k log iss ladai me annaji k sath he..koi cast alag nahi he.. I am really proud to be an Indian.. And the main thing is  that k  this problem is about us.. Common people.. Mujhe lagata tha k hame sehan karne ki adat ho gai he.. yahan har roj kuch naya hota he.. aur hum do din me uss chiz k hisab se jine lagte he..kisi ak akele se insan se ye dunia nahi badalti na chize badalti he.. par aaj usi ak insan ki koshish ne ye rang dikhaya he.. jahan har koi sab kuch bhul k Annaji k support me he.. har age k log he vahan.. log apni job, apni study, family sab chhod k vahan bethe hue he..  but seriously "Don't try Indians patiece".. May be kabhi Annaji ne bhi nahi socha hoga na to kabhi kisi Indian ne k hamara desh sirf ak avaz ban k gunj uthega  without any Violence..

DNA computing


A nano computer  that uses DNA (deoxyribonucleic acids) to store information and perform complex calculations.

In 1994, University of Southern California computer scientist Leonard Adelman suggested that DNA could be used to solve complex mathematical problems. Adelman found a way to harness the power of DNA to solve the Hamiltonian path problem , whose solution required finding a path from start to end going through all the points only once.


Each city was encoded as its own DNA sequence (DNA sequence consists of a series of nucleotides represented by the letters A, T, G, C).

The DNA sequences were set to replicate and create trillions of new sequences based on the initial input sequences in a matter of seconds (called DNA hybridization). The theory holds that the solution to the problem was one of the new sequence strands. By process of elimination, the correct solution would be obtained.


Adelman's experiment is regarded as the first example of true nanotechnology

The main benefit of using DNA computers to solve complex problems is that different possible solutions are created all at once. This is known as parallel processing. Humans and most electronic computers must attempt to solve the problem one process at a time (linear processing). DNA itself provides the added benefits of being a cheap, energy-efficient resource.

In a different perspective, more than 10 trillion DNA molecules can fit into an area no larger than 1 cubic centimeter. With this, a DNA computer could hold 10 terabytes of data and perform 10 trillion calculations at a time.
