Queen of My Empire

Image

When I am alone I miss you, I miss you in sleepless nights;

Even in dreams I see you, and want to make you all just mine;

I miss the day you touched my lips, and the way you wrapped my arm around;

I miss the way you used to love me and those days will never be found;

I miss giving you that beautiful smile, I miss making you laugh;

I miss those days when we were one and you said you were my half;

I miss the wonders we saw together under this beautiful sky;

I promise I won’t repeat the past, I will never again make you cry;

I need the care you gave me once, I need that kiss of yours;

I need the same affection we had while watching the sunset shores;

I cannot help but miss your eyes and the deep ocean within;

The only regret I have today is how much ignorant I had been;

I cannot pretend not to love you anymore, I can’t resist my desire;

Come with me, my love; I promise you, you will be the queen of my empire.

End of the Moore’s Law (The Silicon Era)

What’s Moore’s law? It states that every 18 months or so the computer power of a silicon chip doubles. But, how long do you think it can go on, right ? The computing efficiency of a silicon chip based computer is already on the verge and the rate is slowing down and within 10-15 years from now it will be a flat line. Why? because of overheating of the chips. When the number of silicon atoms used will reduce up to a thickness of 5 atoms of thickness or near, the chip will overheat and destroy itself in the process and as we go down to that extent the quantum phenomenon of the electron would take over and it wouldn’t be bound to a restricting path but it could be anywhere. Therefore we would not be able to do precise calculations anymore. It would be the end of Moore’s law. We no longer would be able to keep up with it using silicon chips in out computers. There would be a huge recession for sure in that period.

Don’t worry though because new candidates are coming up in order to replace the silicon chips. One of them is molecular computers. Do you know how many atoms are required to make up a single bit of memory in our ordinary memory drive ? It takes more than a million atoms; well that’s not that shocking right ! But recently IBM has managed to store a single bit of memory in exactly 12 INDIVIDUAL ATOMS. Yes only with 12 atoms. The ratio to the size of today’s memory bit is ~ 0.000012 time. But the problem with this is its very complicated to built at that scale. Building circuit in that small scale isn’t that easy. But, even with this problem we might be able to make computers with a larger number of atoms. Getting down to the size of atoms in order to compute a problem doesn’t seem like a far stretch any more. We are almost there and you can probably guess the sizes of the supercomputers in the next decade. But getting down to still smaller number of atoms create a huge problem with coherence. The coherence from outside like any kind of small vibrations can even disturb their state and would result into random rubbish in output. But, there is hope. At least we would be able to see molecular computers in the next few decades. This Picture here is taken by a Scanning Tunneling Microscope which can even interact with the atoms individually.

And here’s a model showing how they interact with the magnetic fields of the atoms.

And as you would have heard Quantum Computing has recently gained some popularity among physics enthusiasts. This can use the polarization of a single photon based on the direction of its polarization to store a single bit of date. But as it is in quantum state we would be able to attain a superimposed state i.e. both 1 and 0 at the same time. You might think that’s confusing, how is it going to give us the correct result then ? right ! But, you see when you would be able to attain a state of superposition, we would be able to perform a task with several results. What I mean is previously we used to allot a certain work or response to only two results i.e. 0 or 1 but now we would be able to respond to different polarization angles as well so we can attain any number in between 0 and 1 too. So, there will be an infinite number of responses we can perform according the the signal or information we get from a single polarization of a photon. So think of it this way; if we had to choose the correct path out of a maze which had a millions of possible paths but only one led you out, then a quantum computer can simultaneously will be able to test every possible path there is and will instantly give you the correct path; which a computer would do checking every path one by one. It gives us the ability to compute every possible outcome at a single go which a today’s computer has to do one by one.

But this is a far stretch though. Because, the biggest calculation we have been able to do with just five numbers of atoms (no where near photons) is ‘3 x 5=15’. So you can see how far we have to go. The same advantage of being able to attain more than just two possible outcome in a bit has become its greatest demerit too making it nearly impossible to engineer. To architect a system which can solve problems using these phenomenon will be a revolution in itself and whoever will successfully do that will be the inventor of the century. And let me remind you that we are no where near to make this possible. There is another big hurdle in the way i.e. decoherence. The smallest of vibrations even daily activity like putting the cup on the coffee table or walking near the apparatus is disturbing the synchronization of the atoms. So it is very difficult to maintain their stability. These reasons are what’s making this awesome technology very impossible to make. I hope we would be able to see this technology in my lifetime who knows maybe before the end of this millennium. But, don’t worry even if we won’t be seeing quantum computers in coming decades we might see molecular computers though. Look to two decades ahead and we might find ourselves with molecular computers in our hands and so much better and efficient than today’s technology.

The Universe: just a roll of a dice…

My dear lovely human beings,

I know you don’t understand me and I can say the same about you too. Thanks to education that taught me that I don’t have to beg at some lifeless portrait or statue to fulfill my dreams and thanks to it for it taught me to have faith in myself. People like me who see the beauty in this nature, this universe and its versatility can surely understand how lucky we are to have evolved in this planet and to have understood our world and its deep secrets (although I am not saying that creationists are incapable of admiring the nature). Yes, we are very lucky indeed. Look at this universe, never ending, never seizing, very violent but sometimes very calm.

Don’t get me wrong. I am a religious man but I don’t believe in a creator or GOD as you might say. My religion is science. Religious in the sense that I prosper this universe and science, I certainly have a strong believe in science that we one day would be able to answer everything about this world. It might take a long time but we definitely will be able to answer the biggest mysteries this world. If I started believing in God I would be obligated to believe that any mystery I see is God’s tricks or work and this will never let me accomplish anything. As a scientist, as a human being I am inclined to get curious about everything I see and tend to interact. We are the only species that we know of who is capable of asking questions; we won’t be humans without it, our race would not have survived in this versatile world if it wasn’t for that curiosity. I believe, through scientific developments and new discoveries will change the way we see the world now. And from this prospective we would have understood everything this universe has to teach us and then we would have conquered the universe.

If you understand mathematics you can pretty much predict what the chances are of evolution of an intelligent species in our universe. As we can see it took more than 13.7billion years to convert that lump of weird particles and gases in Big Bang into us; yes, us; we are that special. When the earth came into existence around 4.5billion years ago, who would have thought that such a harsh planet could one day become a home for such a vast ecosystem prospering their livelihood? But, here we are the living proof. Back then there must have been a huge numbers of stars created and still larger numbers of planets along with it which could number in billions and more. But as we see we are the only planet that has life on it. We have been recently able to explore so much of the universe near us (although it’s a tiny fraction), still we are yet to find life on any planet. It’s all about math, it’s all just probability. In such a vast majority of stars and planets we are the only living planet. It all finally comes to the chances of creating the perfect environment for life, a perfect home. What were the chances? We are just a small needle in millions of haystacks.

Image

No, there wasn’t any God, there wasn’t any creator watching over us who created the world out of thin air. But, it evolved. The universe itself evolved within itself like millions of species evolved in our planet; some of its parts were able to sustain life and some weren’t. It was just the matter of chances.

The Evolution of Science

We live in a generation where the biggest discoveries and the biggest questions has raised. Questions that are so fundamental that even a single answer could change the whole world as we know it.

Image

In just the last century the biggest discoveries have been made and new fields of science has been developed to deeply understand the universe we live in. In the last few decades the technology as predicted has exponentially increased its capabilities and still improving each day. Now on this day we are capable of asking ourselves the questions like “can we ever find an alien intelligent life?”, “are there other universes out there?”, “how will the universe end?”, “why is the light’s speed 299 792 458 m / s?”, “does god exist?”, “what is consciousness?”, “can we travel to the past?”. These are the question many of our ancestors have pondered around with to their death bed and which till now has not been answered.

Image

You see, this is the era where we are able to ask the big questions. We can see the that the most basic questions took a very long time to answer like gravity, relativity, electricity etc. But the technology created from it expanded like a virus. And now that these discoveries were made we have faced even greater and more complicated scenario.

Almost 4 billion years ago the earth and the solar system was created. The evolution took this long to make such a beautiful creature who was able to ask questions to himself and the world around it, who is passionate to know the meaning of life, who is able to discover and experiment with the world and tamed the whole world around it.

Maybe we will be able to answer these questions one day too. It may take a long while but I am so happy and fortunate to have born in this era and to witness the biggest revolution that science will go through till now. And gladly I can say that I am up for this roller-coaster ride.

Drops of love… RAIN

I must say I love the rain. Rain brings with it the sweet feeling of happiness. I can stand in the rain forever listening to the sound of the raindrops, feeling the raindrops on my cheeks and imagining any 90s movie scene with me as the hero. I don’t know why but its cold breeze has a wonderful charm on me. The feeling of being free and unpredictable; the feeling of joy and pure happiness; the feeling of just being yourself; that’s all I can ask for.

Image

Some of you will say its the weather for lazy people to sleep off the whole day and believe me when I say this, I am the laziest person I have ever known in my entire life. But rain makes me wanna celebrate and cherish it instead of just lying around day dreaming. I agree its dirty, unhygienic and a recipe for disaster when you would have planned for outing. But that’s the fun part right, not caring about yourself, costly clothes, your brand new shoes or your favorite watch; and just carelessly dancing to the rain. And of-course the thunder is the best thing that can happen when a girl is around. The freezing cold wind giving goosebumps creates such a rush in my blood.

When everyone is in rush to get under a shed or go their homes I like to walk wishing the moment to last forever. It brings a big smile on my face. It gives me the feeling of being in love and makes me forget the world behind me. That’s why I love the rain. Its just a small time vacation from this busy life to a wonderland.
