Artist!

When I was an artist [:(]

Friendship with Gaurds of IIT Delhi

In the morning around 6:30 I am taking a short walk around the hostels. Suddenly one person came from back and said, " Namashkaar ji ". He is none other than our IIT hostel gate's gaurd saab. I replied back, " Namashkaar ji ".
Knowing gaurds really pays you. No need to check my letters. Daily when I go to the desk gaurd saab says, " Sir! aapka Money order hai " or " Sir! aapka registered post hai. patha nahi usme aapka room no galath likha hua hai. " ( My dad has this very bad habit. He writes different room nos each and everytime. )
And whenever I go to computer services center, gaurd saab doesnt ask ID card. Just I enter just giving a small smile at him. Whenever I enter into other hostel I just give a hand shake without showing any ID card.
Moral of the story is just say Hi to everyone with a smile. One day it pays back.

Back to Quantum Mechanics!

Not to forget
Sir Richard P feynman : I think that I can safely say that nobody understands quantum mechanics.

Yes. But what I have in picture I will give you.

Rule : Nothing exists unless until you measure it.

So whatever you observe are the observables. Once you observe it that means you are mesauring it. Like position, mommentum. In order ot measure you should operate observables operator on the Wave Function or what it represents the particle or the system. system can be anything from electron to atom to group of atoms to human anything. now if you want to find the position act the operator for the position on the wave function. Then it gives the position. oooo...wait wait... Im confusiing.

Let me put it in a humorous way.

Suppose a boy wanted to have a relation with a girl. so what are the possibilities. he will have realtion, no relation, or just he will meet her and never meet her again and so and so on....
So if I write the wavefunction of the guy with respect to the variable relationship with the girl.

WF = P1|long lasting realtion>+P2|few days realtion>........+Pn|he will never meet her>

|function> is nothing but a state. |Fn> form a complete orthonormal set. i.e There is no other possibilty.
Now the question is wats the propability of finding the guy with gal. Now operate it with relation operator or multiply it with ket (<> ) and
<>=1 if m=n
=0 for others.
so we get the required Pn value. Pn's are nothig but probabilities associated with each ket.
So now unless until we go and see /observe both we dont know wats the relation between them. Once we measure it All the values dimish and just we see the only relation...

Hope u "dint" understand. Yes you will not....Its nothig but Qunatum Mechanics. No body can understand....as Feynman says. Doubts are abosolutely welcome...to get urself more confused.[:P]

Strategy to kill HIV virus.

First the idea is design nano robots. Which are intelligent enough to detect the right species i.e virus. Then make these robots such that they get sticked to the virus and either it destroys the RNA or simply disables its function by modifying some of the nucleotides. Solution seems very simple no? Then wheres the problem?
The problem is design the nanorobot and teach it how to detect the virus and disable them. Now solution to these problem can be given in two parts.
1. The nano robot. Making it is very tough. But I think it will soon be made. They already claim to make a nano piston. just a few molecules.
2. Now the biggest problem is teacching it. It may require a lot of memory. Then here comes the Quantum computing. Qubits. The quantum bits. nothing but the spin of an electron. When the spin is Up say 1 when its down say 0. Or may be if the probability of finding an electron is more than half then 1 when its less than 0.5 its 0. Anway it doesnt matter whether its first or second. Now the problem is making the Qubit. Once its made you design the rest.
3. Destroying the RNA. Its pretty tough rite now for me to write aboutit. but one thing is that comes into handy is molceular docking. Yes. It requires Biologist, Chemist, Mechanical Engineer( for the docking ) Last but not least a Physicist!

Another way I saw it in New Scientist! ( BTW the above idea is mine. ) The thing is first to kill the virus we have to rip them from the WBC.( White blood cells ) For this I forgot the name. But What it does is it rips of the virus from WBC. Now use the retroviral drugs to kill them.

A flight ticket to Sweeden!

This happened when I was in Germany. My friend and fellow guest researcher Florian Sommerer, Austrian was leaving. He arranged a small party.
We three Dr.Katia Parodi, Florian and myself were talking about Sir. C V Raman, a Nobel laureate in Physics from India. They asked me that Sir. C V Raman used to buy a ship ticket to Sweeden 2 years before he got the Nobel Prize, i.e expecting it from 2 years before, is that true?

Yesterday I remembered this incident and thought may be I should also start buying the Flight ticket every year from now onwards. :))
All the bets Subbu! Nothing can stop you.

Dual nature of my interests.

The branch i opted for is Physics. I am so fascinated with physics that most people from Andhra Pradesh generally prefer Mathematics in which they seem to be more strong. But me being a student of Srinivasa Chary Sir( of Mega Study Cirlce fame. ) , was much more interested in Physics.

All this happened because of my dad. Man he is too practical. I still remember his explaination of 7 continents and 5 oceans and easy way to learn 5 table in LKG. He took a basin of water and put 6 cardpieces with 6 continents names written and an Ice cube with a paper sticked on it named Antarctica. I still have that picture in my mind. And he also explained the platlet movement just by moving these cardboards.

And for the 5 multiplication table he first taught us how to tell the time. Later he just simply asked to multiply the no with 5 and say the time the minute hand shows. He took a lot of pain for myself to pronounce fifteen. I used to say Fiveteen.:)

Around the same time one day it was heavily raining, he brought a bed bulb, bulb holder, battery and long wire. Without changing his wet dress he started connecting the circuit.
In 3rd class Freezing mixture experiment. For this me and my dad wasted almost 8hrs + 1kg of salt. Simply add salt to ice 1:16 ratio and this makes a small cup of water to freeze. These kind of things increased my appetite for Science rather than physics. Opted for MPC group in inter and Engineering Physics in my Engineering.

I love my dad. soooooo much. 21 years happy. then started struggle. Father says beta phataphat IAS banjaa. Beta sochtha hain ki is duniya mein physics ke alawa kuch bhi nahin. Relates everything with Uncertainity Principle and Quantum Mechanics, Nanoparticles, Biophysics...what not.

Never love any two things too much which contradict each other/which makes the other timely impossible. Now if i become an IAS my Physics will end and if I opt for PhD in Physics I will never in my life be an IAS officer. They seem to be complimentary like the wave-particle like Dual nature of matter. If we observe the wave nature then we dont observe the particle nature and vice versa.

Then wheres the problem? I want both. :(((

But there seems to be a hope, a little hope. After an Iranian-American scientist rebels Quantum Mechanics rules where Einstein failed. ( Remember the famous quote : " God does not play dice " )
Rule 1: Nothing exists unless until you measure it.
Rule 2: Ignore the rule 1. ( New one. )

So what exactly this Ashrafar (Iranian-American scientist) does is that he setup ineterference experiment such that he can simultaneosuly know the path of the photon and have the interference pattern. Here the path and pattern are the complimentaries.

Hope that there will be such a logic or solution to my problem too.. that simulataneously I can be an IAS officer and a Physicist. May be in "my" life "my" Dad can be Asrafar for "my" problem. ( Too many my's no? Because as in Bagavadgitha Srikrishna says, " I am the problem. I am the solution. " :P)

Three cheers to Quantum Mechanics.
