A math love song ! :-)

http://www.youtube.com/watch?v=UTby_e4-Rhg

Listen to the song first! Then enjoy the lyrics :)

The path of love is never smooth
But mine's continuous for you
You're the upper bound in the chains of my heart
You're my Axiom of Choice, you know it's true

But lately our relation's not so well-defined
And I just can't function without you
I'll prove my proposition and I'm sure you'll find
We're a finite simple group of order two

I'm losing my identity
I'm getting tensor every day
And without loss of generality
I will assume that you feel the same way

Since every time I see you, you just quotient out
The faithful image that I map into
But when we're one-to-one you'll see what I'm about
'Cause we're a finite simple group of order two

Our equivalence was stable,
A principal love bundle sitting deep inside
But then you drove a wedge between our two-forms
Now everything is so complexified

When we first met, we simply connected
My heart was open but too dense
Our system was already directed
To have a finite limit, in some sense

I'm living in the kernel of a rank-one map
From my domain, its image looks so blue,
'Cause all I see are zeroes, it's a cruel trap
But we're a finite simple group of order two

I'm not the smoothest operator in my class,
But we're a mirror pair, me and you,
So let's apply forgetful functors to the past
And be a finite simple group, a finite simple group,
Let's be a finite simple group of order two
(Oughter: "Why not three?")

I've proved my proposition now, as you can see,
So let's both be associative and free
And by corollary, this shows you and I to be
Purely inseparable. Q. E. D.

Life's Little Instruction Book

Yet another fwd mail, but I simply loved this one.

Life's Little Instruction Book:

Have a firm handshake.

Look people in the eye.

Sing in the shower.

Own a great stereo system.

If in a fight, hit first and hit hard.

Keep secrets.

Never give up on anybody. Miracles happen everyday.

Always accept an outstretched hand.

Be brave. Even if you're not, pretend to be. No one can tell the difference.

Whistle. Avoid sarcastic remarks.

Choose your life's mate carefully. From this one decision will come 90 per cent of all your happiness or misery.

Make it a habit to do nice things for people who will never find out.

Lend only those books you never care to see again.

Never deprive someone of hope; it might be all that they have.

When playing games with children, let them win.

Give people a second chance, but not a third.

Be romantic.

Become the most positive and enthusiastic person you know.

Loosen up. Relax. Except for rare life-and-death matters, nothing is as important as it first seems.

Don't allow the phone to interrupt important moments. It's there for your convenience, not the caller's.

Be a good loser. Be a good winner.

Think twice before burdening a friend with a secret.

When someone hugs you, let them be the first to let go.

Be modest. A lot was accomplished before you were born.

Keep it simple.

Beware of the person who has nothing to lose.

Don't burn bridges. You'll be surprised how many times you have to cross the same river.

Live your life so that your epitaph could read, No Regrets

Be bold and courageous. When you look back on life, you'll regret the things you didn't do more than the one's you did.

Never waste an opportunity to tell someone you love them.

Remember no one makes it alone. Have a grateful heart and be quick to acknowledge those who helped you.

Take charge of your attitude. Don't let someone else choose it for you.

Visit friends and relatives when they are in hospital; you need only stay a few minutes.

Begin each day with some of your favor Apr 27

Send a lot of Valentine cards. Sign them, 'Someone who thinks you're terrific.'

Answer the phone with enthusiasm and energy in your voice.

Keep a note pad and pencil on your bed-side table. Million-dollar ideas sometimes strike at 3 a.m.

Show respect for everyone who works for a living, regardless of how trivial their job.

Send your loved ones flowers. Think of a reason later.

Make someone's day by paying the toll for the person in the car behind you.

Become someone's hero. Marry only for love.

Count your blessings. Compliment the meal when you're a guest in someone's home.

Wave at the children on a school bus.

Remember that 80 per cent of the success in any job is based on your ability to deal with people.

Don't expect life to be fair. Keep Smiling :-)

Engineer vs mathematician

An engineer and a mathematician are sitting in a lounge. Suddenly, the coffee machine catches on fire. The mathematician grabs a bucket and leaps towards the sink, fills the bucket with water and puts out the fire. The second day, the same two sit in the same lounge. Again, the coffee machine catches on fire. This time, the engineer stands up, gets a bucket, hands the bucket to the mathematician, thus reducing the problem to a previously solved one.

Bobby Mc Ferrin

The context in which I came across this video is a bit technical( or 'researchy' if that sounds more classy), but its amazing nevertheless. Have you ever wondered if humans can produce two different tones at the same time ? Birds routinely do this, but in real life, I dont remember noticing anyone doing this for a significant amount of time. ( You can try doing it actually to get a feel of how difficult it is). It turns out that humans inherently have the physical mechanism to produce two tones, just that we have not trained our muscles enough. Some trained vocalists can actually do this !! Check out this video by Bobby Mc Ferrin

One more :

If you are not able to notice it, you can import the file into matlab and view the abrupt jumps in the spectrogram :-)

Wish I could find a er.. 'driver' to activate this incompatible-by-default hardware !! Multi tone-la mokka podalam :-)

Adiye Kolluthey !!


I have been so smitten by this song and literally lost count of how many times I have listened to this in the past 2 days.

I think its one of the best songs in recent times. Rarely in Tamil cinema do we find good Tamil lyrics set to Western tunes ( the last good song I can recollect is yakkai thiri I guess ). The last stanza is especially superb:

"Enakkaghavey vandhai en nizhal polavey nindrai
Unnai thottru nee ennai vendraye !"


Amazing lyrics, superb picturisation ( esp Sameera with her no-nonsense gal character :-) ), Krish, Benny dayal, Shruthi Hassan == Boy, I love this song ! :-)


Adiye Kolluthey azhagho alluthey

Success

To laugh often and much;

To win the respect of intelligent people
and the affection of children;

To earn the appreciation of honest critics
and endure the betrayal of false friends;

To appreciate beauty;
To find the best in others;

To leave the world a bit better, whether by
a healthy child, a garden patch
or a redeemed social condition;

To know even one life has breathed
easier because you have lived;

This is to have succeeded.

Characteristic function and Fourier transform

We were trying to prove that Linear combination of I.I.D Gaussian Rvs produce Gaussian Rvs( not necessarily independent though).

The MGF of Gaussian distribution is as follows:




The usual trick is to calculate the MGF of the sum of the IID Gaussian RVs and after a bit of re-arranging, it can be shown that this MGF has the form of that of MGF of a Gaussian RV.Since the MGF of the sum has the form of that of a Gaussian RV, he concluded that the sum is indeed a RV. I was not quite convinced as to how the inverse would be unique. I asked my prof if he could give some intuition as to how the pdf-MGF pair was unique. He said that one can look at the characteristic function as the Fourier transform of the pdf. Oh boy ! I had never looked at this way. I feel this interpretation is cool.

If - Rudyard Kipling

Recently, Shreenaath had mentioned this poem in Orkut. Brought back memories of my scouting days when I heard abt this poem from Bhuvan anna.

The actual poem :

If

If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you
But make allowance for their doubting too,
If you can wait and not be tired by waiting,
Or being lied about, don't deal in lies,
Or being hated, don't give way to hating,
And yet don't look too good, nor talk too wise:

If you can dream--and not make dreams your master,
If you can think--and not make thoughts your aim;
If you can meet with Triumph and Disaster
And treat those two impostors just the same;
If you can bear to hear the truth you've spoken
Twisted by knaves to make a trap for fools,
Or watch the things you gave your life to, broken,
And stoop and build 'em up with worn-out tools:

If you can make one heap of all your winnings
And risk it all on one turn of pitch-and-toss,
And lose, and start again at your beginnings
And never breath a word about your loss;
If you can force your heart and nerve and sinew
To serve your turn long after they are gone,
And so hold on when there is nothing in you
Except the Will which says to them: "Hold on!"

If you can talk with crowds and keep your virtue,
Or walk with kings--nor lose the common touch,
If neither foes nor loving friends can hurt you;
If all men count with you, but none too much,
If you can fill the unforgiving minute
With sixty seconds' worth of distance run,
Yours is the Earth and everything that's in it,
And--which is more--you'll be a Man, my son!

--Rudyard Kipling


Another nice read is :

ABRAHAM LINCOLN’S LETTER TO HIS SON’S TEACHER

He will have to learn, I know,
that all men are not just,
all men are not true.
But teach him also that
for every scoundrel there is a hero;
that for every selfish Politician,
there is a dedicated leader...
Teach him for every enemy there is a friend,

Steer him away from envy,
if you can,
teach him the secret of
quiet laughter.

Let him learn early that
the bullies are the easiest to lick...
Teach him, if you can,
the wonder of books...
But also give him quiet time
to ponder the eternal mystery of birds in the sky,
bees in the sun,
and the flowers on a green hillside.

In the school teach him
it is far honourable to fail
than to cheat...
Teach him to have faith
in his own ideas,
even if everyone tells him
they are wrong...
Teach him to be gentle
with gentle people,
and tough with the tough.

Try to give my son
the strength not to follow the crowd
when everyone is getting on the band wagon...
Teach him to listen to all men...
but teach him also to filter
all he hears on a screen of truth,
and take only the good
that comes through.

Teach him if you can,
how to laugh when he is sad...
Teach him there is no shame in tears,
Teach him to scoff at cynics
and to beware of too much sweetness...
Teach him to sell his brawn
and brain to the highest bidders
but never to put a price-tag
on his heart and soul.

Teach him to close his ears
to a howling mob
and to stand and fight
if he thinks he's right.
Treat him gently,
but do not cuddle him,
because only the test
of fire makes fine steel.


Let him have the courage
to be impatient...
let him have the patience to be brave.
Teach him always
to have sublime faith in himself,
because then he will have
sublime faith in mankind.

This is a big order,
but see what you can do...
He is such a fine fellow,
my son!

Copyright & information theory

Came across this at http://yann.lecun.com/ex/fun/index.html

"All copyrights and trademarks are property of their respective owners".
Bleeding-edge research in a new branch of mathematics (the application of non-standard elliptical analysis to information theory), has recently proved that the above sentence carries exactly 0 bit of information.
Researchers in yet another field of applied mathematics (applications of non-standard elliptical analysis to decision making) have conjectured that only the fear of lawsuits will drive people to write sentences with provably zero information content !


I was not able to track the original paper, anyway I think this is cool !

36 Methods of Mathematical Proof

36 Methods of Mathematical Proof
http://osl.cs.uiuc.edu/~ksen/proof.html

Some are particularly nice ;-)

Proof by obviousness
"The proof is so clear that it need not be mentioned."

Proof by general agreement
"All in favor?. . . "

Proof by intimidation
"Trivial."

Proof by mumbo-jumbo

" (B Ì P ) , $ (C Î W )

Proof by profanity
(example omitted)

Proof by illegibility
(scribble, scribble) QED

Proof by clever variable choice
"Let A be the number such that this proof works. . "

Proof by intuition
"I just have this gut feeling. . ."

Top 10 most stupid questions people usually ask in obvious situations

1. At the movies:
When you meet acquaintances/friends…
Stupid Question:- Hey, what are you doing here?

Answer:- Dont u know, I sell tickets in black over here..

2. In the bus:
A heavy lady wearing pointed high-heeled shoes steps on your feet…
Stupid Question:- Sorry, did that hurt?

Answer:- No, not at all, I’m on local anesthesia…..why don’t you try again.

3. At a funeral:
One of the teary-eyed people ask…
Stupid Question:- Why, why him, of all people.

Answer:- Why? Would it rather have been you?

4. At a restaurant:
When you ask the waiter
Stupid Question:- Is the “Butter Paneer Masala” good??

Answer:- No, its terrible and made of adulterated cement. We occasionally also spit in it.

5. At a family get-together:
When some distant aunt meets you after years
Stupid Question:-Munna,Chickoo, you’ve become so big.

Answer:- Well you haven’t particularly shrunk yourself.

6. When a friend announces her wedding, and you ask…
Stupid Question:- Is the guy you’re marrying good?

Answer:- No,he’s a miserable wife-beating ,isensitive lout…it’s just the money.

7. When you get woken up at midnight by a phone call…
Stupid Question:- Sorry. were you sleeping?

Answer:- No. I was doing research on whether the Zulu tribes in Africa marry or not. You thought I was sleeping…. you dumb witted moron.

8. When you see a friend/colleague with evidently shorter hair…
Stupid Question:- Hey have you had a haircut?

Answer:- No, its autumn and I’m shedding……

9. At the dentist when he’s sticking pointed objects in your mouth…
Stupid Question:- Tell me if it hurts?

Answer:- No it wont. It will just bleed.
