Sizzling Schumi


Gone are the days when F1 was a one man show with the German maestro who with this dexterous hands drove the red-machine to victory every other time. The driver, who had fans almost equal to Michael Jackson, made people frantic about this racy sport at least for a decade. Ferrari was its career best when schumi was its driver along with Barrichello. Both these men made sure that victory was the only result for the Ferrari, whatever circuit may it be, Silverstone, Magny Cours or Sepang. It was akin to the wave of the magician's wand when Schumi waves to the crowd atop the podium.


But then, every good run must come to a halt and so did Schumi. Fortunately, not for Ferrari. The Massa-Raikkonen duo seem to be doing a better job in retaining the name that the red-machine had during the tenure of Schumi. On the other side, the podium seem to enjoy this season with winners changing from circuit to circuit and this variety in the race results have also made F1 fans happy. The dominance of Schumi also yielded a boring sensation from other F1 patrons who felt that the sport had become one sided. But now, each race brings in different adventures, neck to neck podium finishes ( which was a rare phenomenon during Schumi's period when the German lead the race by more than a minute). In all, though the retirement of the flying German made F1 fans heavy hearted, it has also sparked a new phenomena of variety and surprising minutes in the world of F1 sport.

Trust


Trust goes a long way in maintaining almost every kind of relationships. An employer must trust his employee that he will produce best results. This trust gives the motivation to the worker and he ultimately gives his best. A father must trust his son/daughter that he/she will come out with flying colors. The trust of his/her father will naturally induce the much needed responsibility to achieve the goals. The trust of a father is the best motivation a child needs to progress. In team games, the Captain needs to trust his players so that there exists a cordial relationship among the players and also between the players and the Captain. Lack of trust from the Captain will induce negative thoughts into the minds of the players.

When it comes to friendship, trust means a lot. One must trust their friends always. This trust does not come in just a matter of days' acquaintance. It takes a much longer time to build this trust. The situations during which you don't let down your friends are the basic building blocks of trust. The real show of trust is exposed when you support your friend(s) when the whole society is against him/her/them, when there is nothing wrong on his/her/their part. Trust helps in building strong relationship. Lack of this trust among friends will lead to superficial relationships that may break down at any time.

The most important trust, which I believe is to "trust yourself". You need to trust yourself that you are capable. Trust yourself that you are born to win. Trust yourself that you will bring glory to your nation, to your parents, to your family and all your well wishers. Have the trust in yourself that whatever job you undertake, will surely end in success. This trust in yourself is the first step to victory. This trust will put you miles ahead of your competitors and will surely help you scale greater heights. Failing to trust yourself will bring all your skills to nonentity. So, understand how vital it is this "trust" and try to incorporate this virtue into your life as soon as possible. Once you do this, you will have better relationships and success will become a habit!

Quantum Computing


Gone are the days of Classical Computers that are designed using transistors. The era of Quantum Computing has dawned. A quantum computer works under the quantum mechanical principles of superposition and entanglement. In a classical machine data is stored in bits, whereas in a quantum machine data is stored as qubits (Quantum Binary Digits). The basic idea of quantum computing is that the properties of quantum can be used to represent data and quantum mechanics can be used to perform operations on this data.


The efficient use of quantum machines will be in the field of cryptography for cryptanalysis. The Shor's algorithm which aims to solve or crack the RSA algorithm will work perfectly in polynomial time if quantum computers are used. The RSA algorithm can be cracked if we are able to factorise a number 'n' into the two primes that constitute the product. The Shor's algorithm finds those two numbers in polynomial time while the other algorithms can solve only in exponential time.


The problems solvable by quantum computers area called BQP, "Bounded Error, Quantum Polynomial time". Quantum computers run only "probabilistic" algorithms. A quantum computer is said to "solve" a problem if for every instance the solution it provides is right with high probability. Even though, quantum computers are faster than the classical computers, quantum machines can't solve problems that are not solvable by classical machines. Since the quantum machines can be simulated using "Turing Machines", quantum computers cannot solve undecidable problems. But, a realization of quantum computers, which is still in the research phase, will add a new dimension to the Computer Science.

Nature and Discretion


It was those periods of mankind when man knew nothing of this Universe and of the Earth. He was roaming over this planet as a pristine being and dint have rational thinking powers and powers of discretion. Life was peaceful as he ate the Mother Nature's offering of fruits and vegetables, and of course some animals. He was completely dependant on Nature and was thankful for what the Mother has given him.


Then this mind of man started pondering over things as to make life easy, it was then the wheel was invented, to make transport easier. This rational thinking of man did not stop with this and ventured deep into inventing many more things that made his life more easy. This led to a well settled life and a better understanding of the laws of nature. But, the confusing aspect, which I view, is when nature was sure in making the rules governing the Universe a profound for humans, why did we strive much to understand this recondite concept? Why do we strain ourselves beyond our limits to get things cleared about the periodic happenings of Earth and the Universe? Call it discretion or violation of the living rules?

Man was for long years only because he enjoyed the nature's offerings and dint get beyond his limits. He was in harmonium with nature and he enjoyed the every speck of his surrounding. The competition among the humans led to acquirement of wealth, leading to imbalanced distribution of property. This gave rise to greed and jealousy. Man had to think more and more to get over the other person and this led to a life of misery and man detached away from the pleasures of nature. He neglected nature and concentrated more on material life. Material benefits became a matter of prime importance for him and respect for humans was completely lost.

The life we lead today is not for us, but for our status, for what we want people to think of us, for what dignity we want in our society and so on... Many of us forget what happiness is and get ourselves going with this world. We don't spend a minute a day to think of what our real interests are and are we pursuing our passion. In today's world enjoying the nature and admiring it is too ambitious but try to make sure that you don't get yourself hooked up with the thought that you control the nature with technology and other gizmos. One thing that is proven right for sure is that our lifetime is strongly reduced once these innovations came into practice. In the older times people lived hale and healthy for longer years but now we battle with nature to keep ourselves alive!! One thing which I feel dangerous is that, too much investigation into something which is deliberately kept abstruse will bring unpleasant results unless it is done on gregarious grounds, example exploring "Nature".

Just for Laughs


~~~~~~~~~~~~~~~~~~~~~~~~~
A programmer is walking along a beach and finds a lamp. He rubs the lamp, and a genie appears. "I am the most powerful genie in the world. I can grant you any wish, but only one wish."
The programmer pulls out a map, points to it and says, "I'd want peace in the Middle East."
The genie responds, "Gee, I don't know. Those people have been fighting for millenia. I can do just about anything, but this is likely beyond my limits."
The programmer then says, "Well, I am a programmer, and my programs have lots of users. Please make all my users satisfied with my software and let them ask for sensible changes."
At which point the genie responds, "Um, let me see that map again."

The Enigma Cipher



There is an interesting encryption technique using some hardware called "three rotor machine" or "The Enigma Cipher". The device was invented by the Germans during the II World War. There will be three rotors, to start with. The plain text will be typed in through the key board. When the first character is typed, it passes through the first rotor and gets encrypted according to the position of the rotor, because the rotor has 26 teeth, one for each alphabet. The first rotor passes it's output to the second rotor and the encryption takes place according to it's position, similarly with the third rotor. The new letter that we get for the plain text character, will be bounced off a reflector and we obtain at the first rotor.


The beauty of this machine lies in the complexity that it imposes by rotating. Initially, the first rotor makes its first move for the first character and the other two rotors remain stationary. Once the first rotor completes 26 moves, the second rotor makes a single move. Even now the third rotor is stationary. Till now, we have 26x26=676 combinations, coz the first rotor makes 26 moves for each of the 26 teeth in the second rotor. When the second rotor completes 26 moves, the third rotor makes a single move. The entire process repeats now. To sum it up, we have 26x26x26=17576 combinations.



The initial position of the rotors act as the key. The decoding people must know the initial configuration to decode the message. In those times, the configuration was written on a diary which had the configuration for each day. This was insecure, coz if someone happens to get the diary, he may form the machine of his own. The Enigma cipher was broken(decrypted secretly) by Alan Turing (In picture) and group of scientists for America. Had this not been broken, the Germans would have had a different course of war!
