Matches Piles Puzzle

The matches piles puzzle , actually a game that is very widely played

The game is as follows:
Make three piles of matches, the first pile containing three matches
the second containing four matches
the third containing five matches...

Each player can pick any number of matches from any but one of the pile on his/her turn. For example player 1 picks 1 match from pile 1 , player 2 picks 3 from pile 2 etc...
Both the players keep on picking the matches one by one on their turns. The one picking the last match will be the looser

Given that all the players play a perfect game, who amongst the player starting first and second will win the game!!

The Triangle Rearrangement Puzzle

You must have come across this puzzle many a times that said you have a triangle that have different tiles arranged in it. Now when you rearrange those tiles in the same triangle there is a place in the triangle that is unfilled. Now how can that happen?? Try it make cut outs on paper , rearrange them. It really happens, the first triangle was completely filled but later there is a tile of 1x1 size missing in the triangle
The puzzle rearrangement of triangle is as follows:Now how is that possible?

Solution to the so called Triangle Rearrangement or Disappearing Tile Puzzle (click here) :

It just looks as if the both the triangles are of same size, but actually they are not. There is only a slight difference in both the triangles which you tend to miss out even when you try them on paper cut outs, thinking that you were not perfect with cutting!!
The main difference comes in the inclined line of the triangle, i.e. the slope of the line.
The small change is slope is from 0.4 to 0.375. This small change is enough to accommodate the area of 1x1 area in the triangle.

My Stupid Suicide Plan - CHETAN BHAGAT

Found somewhere!! Really tells the story of most of the IITians. May not always be the suicidal but it comes as i have seen in my IIT Tenure, may it be a topper or average or loser. It really have a darker side. Many of the successful and unsuccessful don't even come to notice. Even the person 3-4 rooms away wont even know it. So here it is by Chetan Bhagat :

Last week, an IITian committed suicide. People who commit suicide do it when they feel there's no future. But wait, isn't IIT the one place where a bright and shining future is a foregone conclusion? It just doesn't add up, does it? Why would a young, hardworking, bright student who has the world ahead of him do something like this? But the answer is this-in our constant reverence for the great institution (and I do believe IITs are great), we forget the dark side. And the dark side is that the IITs are afflicted by the quintessential Indian phenomenon of academic pressure, probably the highest in the world.

I can rant about the educational system and how it requires serious fixing, or I can address the immediate-try my best to prevent such suicides. For this column I have chosen the latter, and I do so with a personal story.

News of a suicide always brings back one particular childhood memory. I was 14 years old when I first seriously contemplated suicide. I had done badly in chemistry in the Class X half yearly exam. I was an IIT aspirant, and 68% was nowhere near what an IIT candidate should be getting. I don't know what had made me screw up the exam, but I did know this, I was going to kill myself. The only debate was about method.

Ironically, chemistry offered a way. I had read about copper sulphate, and that it was both cheap and poisonous. Copper sulphate was available at the kirana store. I had it all worked out.

My rationale for killing myself was simple-nobody loved me, my chemistry score was awful, I had no future and what difference would it make to the world if I was not there. I bought the copper sulphate for two rupees-probably the cheapest exit strategy in the world.
I didn't do it for two reasons. One, I had a casual chat with the aunty next door about copper sulphate, and my knowledgeable aunty knew about a woman who had died that way. She said it was the most painful death possible, all your veins burst and you suffer for hours. This tale made my insides shudder. Second, on the day I was to do it, I noticed a street dog outside my house being teased by the neighborhood kids as he hunted for scraps of food. Nobody loved him. It would make no difference to the world if the dog wasn't there. And I was pretty sure that its chemistry score would be awful. Yet, the dog wasn't trotting off to the kirana store. He was only interested in figuring out a strategy for his next meal. And when he was full, he merely curled up in a corner with one eye open, clearly content and not giving a damn about the world. If he wasn't planning to die anytime soon what the hell was I ranting about? I threw the copper sulphate in the bin. It was the best two bucks I ever wasted.

So why did I tell you this story? Because sometimes the pressure gets too much; like it did for the IITian who couldn't take it no more. On the day he took that dreadful decision, his family and friends were shattered, and India lost a wonderful, bright child. And as the silly but true copper sulphate story tells you-it could happen to any of us or those around us. So please be on the lookout, if you see a distressed young soul, lend a supportive, non-judgmental ear. When I look back, I thank that aunt and that dog for unwittingly saving my life. If God wanted us to take our own life, he would have provided a power off button. He didn't, so have faith and let his plan for you unfold. Because no matter how tough life gets and how much it hurts, if street dogs don't give up, there is no reason why we, the smart species, should. Makes sense right?

Really makes sense!!

Lights out Puzzle Revisited - the solution

Solution to the puzzle game Lights out Puzzle posted on 10th June 2007

Looking at the puzzle from a mathematical perspective, with a small board like this we can solve the problem on paper. The way would be to formulate this problem as a system of linear simultaneous equations in modulo 2 number system. Then it can be solved using gaussian ellimination or if the matrix comes out to be symmetric cholesky decomposition can also be used.
Since, for different board (bulb) configurations matrix doesn't change, a single LU (or some similar) decomposition will suffice. Once, we have such decomposition available, all board configurations can be easily solved easily on paper.

The other generic way for solving any board size for such puzzles is the following C Program based on exponential complexity!! If the problem is really solvable, the program is sufficient to do this.
Download the code here : Lights out puzzle Code in C

How to survive changes - Corporate Lessons

Three lessons from large corporations to help you survive change….

Lesson 1:
A crow was sitting on a tree, doing nothing all day.
A small rabbit saw the crow, and asked him, "Can I also sit like you and do nothing all day long?”
The crow answered: "Sure, why not.”
So, the rabbit sat on the ground below the crow, and rested.
All of a sudden, a fox appeared, Jumped on the rabbit... and ate it.

Moral of the story :
To be sitting and doing nothing you must be sitting very, very high up.

Lesson 2:
A turkey was chatting with a bull.
"I would love to be able to get to the top of that tree," sighed the turkey, "but I haven't got the energy.”
"Well, why don't you nibble on some of my droppings?" replied the bull. They're packed with nutrients."
The turkey pecked at a lump of dung and found that it actually gave him enough strength to reach the first branch of the tree.
The next day, after eating more dung, he reached the second branch. Finally after a fortnight, there he was proudly perched at the top of the tree Soon he was spotted by a farmer Who promptly shot the turkey out of the tree.

Moral of the story:
Bullshit might get you to the top, but it won't keep you there.

Lesson 3:
A little bird was flying south for the winter.
It was so cold, the bird froze and fell to the ground in a large field.
While it was lying there, a cow came by and dropped some dung on it.
As the frozen bird lay there in the pile of cow dung, it began to realise how warm it was. The dung was actually thawing him out!
He lay there all warm and happy, and soon began to sing for joy.
A passing cat heard the bird singing and came to investigate.
Following the sound, the cat discovered the bird under the pile of cow dung, and promptly dug him out and ate him!

Moral of the story:
1) Not everyone who drops shit on you is your enemy.
2) Not everyone who gets you out of shit is your friend.
3) And when you're in deep shit,
keep your mouth shut

Y2K Bug caused global warming !!!!

Great article for the climate bugs that said
Not only are the methods for gathering climate change data inaccurate, but there was also a bug in the NASA Climate Data. As it turned out, a Y2K bug caused 1998 to appear as the hottest year on record, when in reality 1934 was. Also, after NASA corrected their records, 5 of the 10 hottest years on record occurred before WWII (after WWII, industry boomed, and CO2 levels began to rise). If human activity is supposed to be the cause of global warming, how can the 5 years before industry boomed be explained?
Well now, even the the global warming sounds dubious. Everything is supposed to be because of the human activities around. But not even the used bombing in WW II could make an effort to be the hottest year.
Get more about the same at Changing The Climate Change Models…

Solution to Microsoft Direction Puzzle

The solution to the Microsoft Direction Puzzle posted on 25th July. Please visit the puzzle if unseen.

Several suggested a set of points 1 mile north of the South Pole. This is not a legitimate answer, because once you arrive at the South Pole, you can not proceed to "walk" eastwardly. Any forward motion whatsoever is, by definition, northward. And I just can't accept stationary spinning as a form of walking.

However, that is very close to the answer, both in concept and in location. Back up an infinitesimal distance further north (slightly more than a mile away from the South Pole). You now have a "ring" around the globe, an infinite set of points all slightly more than a mile away from the South Pole. From any one of these points, following the southern directed 1 mile trek, you will end up just north of the South Pole. You now *can* walk east for 1 mile. You will complete a LOT of tiny circles around the South Pole. If your rings of starting points was located at the proper distance away, you will complete the 1 mile eastward trek exactly where you started that leg of the journey (completing exactly "N" circles). And then you can follow your path in the snow (north this time) back to the exact starting point!

But wait, that's not all. Let's start over. This time start from another ring that is slightly further north. Just the right distance away from the South Pole so that your eastward 1 mile trek will complete exactly "n-1" complete circles. Now you have found 2 rings, each with an infinite number of points.

As you might imagine, you can keep backing up further north, creating add'l starting point rings, until you are about 1.16 miles away from the South Pole, at which point, following your 1 mile southward trek, your eastward leg will complete only 1 full circle. At this point, you will have found "N" rings.

So, you will have N rings starting just slightly more than 1.00 miles away from the South Pole, and ending at about 1.16 miles away.

N = infinity, since the closer you get to 1.00 miles away will work, as long as you can complete exactly "n" circles during the eastward trek. As you can see, there are actually "I^2+1" points that work, where I = infinity. The "+1" brings in the one point in the Northern hemisphere that also works, which is, of course, the North Pole (pick either true or magnetic north).

Needle in a haystack Puzzle (Intuitional Puzzle)

Intuitions plays this puzzle. Lets work on finding the needle in the haystacks
It follows:
You are one of ten contestants in the game described as below:
A field contains 100 haystacks, 10 of them have a needle. On entering the field, the first contestant searches haystacks until he finds one that contains a needle. Assume that his search of each haystack is exhaustive - that is, if he can't find a needle in the haystack, there isn't one. Assume also that each needle is hidden deeply enough within its haystack that it cannot be found without seriously disturbing the haystack.

The second contestant then enters the field, and searches haystacks until he too finds a needle. He will not search any of the haystacks searched by the first contestant, because he knows that they never contained or no longer contain a needle. Each subsequent contestant repeats this process. The winner is the contestant who has searched the fewest haystacks before finding a needle.

Suppose that you could choose whether to be the first, second... tenth contestant. Would your intuition tell you:
1. choosing to search after certain number of contestants, at what position?
2. it doesn't really matter (the positions), choose any
Do tell the reasons for doing so!!
