Atkins

This must be very familiar name to the peple who wants to loose weight. The famous Atkin's diet. What they plan is High protein diet. But I always doubt about it. Beacuse our body has this mechanism to convert proteins to carbohydrates & vice versa.
So may be I have to clarify this...

Patience!

Haa...this word is the one like I went to extremes of it.
The two classic examples I give you are like this :

1. MY suitcase is numberlocked. While travelling somehow the no changed. Its a four digit no. Then I tried all the 9999 nos and it took almost 2 hours. But still it din't so I have to break it up.
2. Once I wanted to delete all my scraps in my profile of orkut. Like there are more than thousand scraps. And not only that I wanted to delete the ones that I replied in others also. Then it roughly amounts to 2000 odd...Then I started and the whole night I was searching for scraps in others scrapbooks and deleting deleting and Finally I almost acheived the task. Except that I wanted to leave few scraps in my scrapbook which I liked.

Then where is the Flaw!

Many times I like to find the flaws in the problems. Like the one I will demonstrate to you which my friend Banta explained to me.

If the professor sasy that next week there is a Surprise quiz. Then Banta argues that there will not be any quiz next week!

His argument goes like this. If its a surprise quiz then it can't be on Friday because till thursday there is no quiz mean then Firday there will be a surprise quiz and its no more surprise. As we know damn sure there is a quiz. Then if Friday there is no quiz then on Thursday there can't be a surprise quiz because till wednesday there is no quiz then on Thursday it will not be a quiz.( As Friday there will not be a quiz. )
Then by similar argument there will not be a surprise quiz on Wednesday, Tuesday and Monday! Voila!( bad usage )Then next week there isnt any quiz.

Now where is the Flaw?

Dirac-Fisherman fishing problem!

The problem goes like this.

Three fihserman go fishing in the middle of a stormy noght. They catch some fish, then land on a desert island and go to sleep. Later one of them wakes up and he says to himself, " I'll take my one third of the fish and I'll go away. " So he divides them into three parts. He finds one extra fish. He throws the extra fish into the sea. Then he takes his share and leaves that place. Next fisherman does the samehting...divides into three parts, one extra fish is left. Throws that into the sea. ( Without knowing that the first fisherman departed. )
Finally the third one also wakes up. Then he too does the samething. Divides it into three parts and throws the extra fish into the sea.
Now the question is, " What is the minimum number of fish? "
WHy Dirac comes into picture? Because it was given quickie problem to him at St. John's college. Quick as a flash he gives the answer as minus two.

The reasoning for the minus two is : Minus one + minus one + minus one + plus one = minus two. Now divide into three the extra one is plus one. But you have to throw the plus one into the sea. again minus two.
Clearly you must add a definite positive no. to get a sensible no fish.( of course positive.)
Answer : 25 ( Solved by me! )

[ The above problem is taken from the book " Unification of fundamental forces " by Sir. Abdus Salam, Nobel prize winner along with Sir. Weinberg and Sir. Glashow for Unification of wek forces with Electromagnetism. Hmmmm....I'm on the track. ]

Too hilarious...on http://manjuvijay.blogspot.com

Just I was browsing through Orkut and found a blog of lady Manju from BITS-Pilani. The posts were very long. Somehow I coul manage to read this post. Trip from Delhi to Pilani May be the reason might once me saran shivaji asif had the same but not this kind of experience.
Man the above post I mentioned i too hilarious. Its big but do have a look at it.
Go Manju go...thats all I can say to her...

My Dad & Me

One day may be two days...ok one, two days back three persons were walking.
I was just passing by and saw them. Mother Father and his Son. Father is putting his hand on his Son and walking.
So, I remembered my Daddy. Because whenever we used to have a walk I used to put hand on him and used to walk like that. Let me tell you one thing. Except his height I am an exact clone of him. When we walk there goes hell lot of discussions.
Let me give some examples.( some conversations might be in telugu )

Daddy asks, " Nanna...nuvvu chese project entra? "
Myself " Daddy...naadhi nano particles midha. "
There comes the first question.
Daddy " nanparticles ante entra pedha? "
Myself " daddy nano particles ante ippudu sudha mukka ni rendu baagalu cheyyi entha 2.5 cms kadha. malli rendu mukkalu cheyyi...1.25 malli ila chesukuntooo pothuu unte... oka stage lo aa particle size konni nanometre's size vachevaraku ante... millimetre lo 10 lakshalo vanthu anamata...dani valla bollanni advantages untai daddy. like many things... "
No there comes another question from daddy , " avunura pedha Dr. Vijay Prakash garu enti research papers publication antunnaru. ante enti? "
My self , " Ante adhe daddy monna naa paper publish ayyindhi ante..ee news paper lo annavu chudu adhi. Actually entante ante to say to the world that Yes I did it first than anyone revealing some mystery of nature or something... "
Now its my turn , " Daddy Habeas Corpus writ ante adhi fundamental rights lo Right to Constitutional remedies kindhaki vasthundhi kadha "
daddy says , " Yes correct. ante evaranna e writ kindha case files chesthe the person or the victim should be presented to the court within 24 hours. inka ilani writ of mandamus, certiorari, quo warranto.. "
And he says.. " Do you know what is perestroika glasnost? "
I say , " That one termed by Gorbachev. appudu cheppav kadha. "
daddy says, " Yeah...Russia lo emayyedhi ante...lopala antha poverty. bayataki maathram emi thelavanichevaru kadhu. so appudu Gorbachev vachi yes we will open it ani...Perestroika meaning Openness... "
Whenever he wants to say greatness of India, " Orei pedha ippudante mana vallu inni scientific equipments vachayi kaanni....appatlo mana munulu veellu antha eppudo BC nati kaalam lo panchangam lo rasesaru kadha... "
It goes on like that for hours..some times these kind of discussions go on while my dad is driving the scooter. He is too fast. Sometimes there times it reaches to a speed of 80 on scooter...ooof...but still confident.
Whenever we go to books shop or exhibition we take gud amount of money. When we see some book cover page. Daddy...that is the nuclear reactor design. He says pointing to interpretation of dreams " he is sigmund freud. "
Whenever he goes out he asks , " what shall I bring for you? "
Some times my answer is , " Daddy.. Medical dictionary pattukunira daddy " or " Dad get me Psychology by Morgan et al " or " Mahaprasthanam " or " nothing "
He brings books with two others which he likes, like Firadousi( By Gurram Jaashuva ) and some Furits or mirchi bajji or something.
like these it goes on......

Extension of Feynman's Problem Solving Algorithm!

After reading the post of Sasikanth, I thought of extending the Algorithm.
The Original one goes like this :

The Feynman Problem-Solving Algorithm:
(1) write down the problem;
(2) think very hard;
(3) write down the answer.

Subbaraju's/Subbu's Extension of Feynman's Problem Solving Algorithm:
(1) write down the problem;
(2) think very hard;
(3) write down the answer.
(4) if the answer is true/consistent then end else go to step (1)

Subbu's trick to Nobel Prize!

[This might be boring to ppl who are not that interested in physics]

Yes! Are you desperate to win a Nobel Prize? Then there a very simple way to bag it. All the big shots in Physics are Unifiers. That is what they do is just simply unify two things.
Like see Electricity and Magnetism -- Faraday and Ampere.
Electromagnetism and Radiation -- Maxwell
Terrestrial Gravity and Earthly gravity -- Newton
Electromagnetism and Weakforces -- Weinberg, Salam and Glashow

Now to get the Nobel Prize ( Already Weinberg, Salam and Glashow got their piece for Unifying weak and force and electromagnetism. ) just unify gravity and Electromagnetism or Strong interactions with Electromagnetic ones. Well I would choose unifying Strong Interactions and Electromagnetic interactions. Beacuse already Eistein tried and died unifying gravity and electromagnetic interactions. ( in a sarcastic way. )
Well once again I have to make a point in choosing Theoretical Physics because its doesnt require big big equipments or laboratories. Just a few books pen/pencil and may be a computer with internet.
All the Best!

Fever( Biology revisited )

Now a days I am having a preiodic doses of normal fever. So what happens when there is fever? Or let me put it this way. What is fever?
Anybody temperature elevation above 100 degrees Farenheit.
How do we get fever?
There is an organ in our body called Hypothalamus which is located in the brain is the one which controls the temperature. Its like the thermostat of the body. So, when the thermostat is set to a higher temperature i.e above 100 degrees Farenheit,then the condition is known as Fever. High metabolism, rush of blood to the cooler parts that is to the skin, shivering of muscles to generate heat are the effects.
How do we control fever?
Just say to the hypothalamus to reset to normal temperature. That is by some chemical messenger like aspirin or paracetamol( more famous in US as Tylenol )
When you dont have these just try the bark of willow tree which has salicin which is a crude form of Salicylic acid. Well aspirin is Acetytl Salicylic acid. It is also used to save patients from minor strokes.
Coming to paracetamol or tylenol, chemically p- acetylamino phenol.
What they do is just resets hypothalamus to a lower temperature. For best results take paracetamol 6hourly. Take two more tablets even after fever is gone.
Warning!! Take care of the intake of aspirin. It can be dangerous.

Coming to the malarial fever caused by plasmodium malariae ( in which case fever is periodic with a period of approximately 72hrs ) or plasmodium vivax take dose of quinine. Or crudely from the bark Cinchona ( Cinchona Officinalis ) which has this alkaloid quinine.
Ok! thats it. I know this much only....

caffeine/teaine

What is the alkaloid in coffee?
Straight away the answer is Caffeine.

Now what is the alkaloid in tea?
The answer is little bit time dependent. Time dependent in the sense if you asked the same question 8 or 9 years back the answer is " Teaine ".
But later they found it to be the same as Caffeine. First when they found this alkaloid they put the name as Teaine. Later its structure resembled caffeine.

As a fact tea in its raw form has more caffeine than coffee( in raw form ). But when you prepare tea and coffee coffee has more caffeine than tea. And tea has antioxidants ( which help in fighting cancers and heartattack ) in which many times they are not available naturally.
