Cool Space Facts

Everyone loves facts about the space.Everyone is intrigued by it .The chapter on space in the science books always seems the easiest one ,why? Because it's always interesting .
I was 'stumbling' around when i saw a cool space fact which inspired me to look up even more of them.Here are some of the ones i liked:

If you put Saturn in water it would float
The density of Saturn is so low that if you were to put it in a giant glass of water it would float. The actual density of Saturn is 0.687 g/cm3 while the density of water is 0.998 g/cm3. At the equator Saturn has a radius of 60,268 ± 4 km – which means you would need an extremely large glass of water to test this out.
      The light hitting the earth right now is 30 thousand years old
The energy in the sunlight we see today started out in the core of the Sun 30,000 years ago – it spent most of this time passing through the dense atoms that make the sun and just 8 minutes to reach us once it had left the Sun! The temperature at the core of the sun is 13,600,000 kelvins. All of the energy produced by fusion in the core must travel through many successive layers to the solar photosphere before it escapes into space as sunlight or kinetic energy of particles.

The Sun loses up to a billion kilograms a second due to solar winds
Solar winds are charged particles that are ejected from the upper surface of the sun due to the high temperature of the corona and the high kinetic energy particles gain through a process that is not well understood at this time. Also, did you know that 1 pinhead of the sun’s energy is enough to kill a person at a distance of 160 kilometers?
         The moon is drifting away from Earth
Every year the moon moves about 3.8cm further away from the Earth. This is caused by tidal effects. Consequently, the earth is slowing in rotation by 24 leap seconds since 1972. Scientists do not know how the moon was created, but the generally accepted theory suggests that a large Mars sized object hit the earth causing the Moon to splinter off.
 If two pieces of metal touch in space, they become permanently stuck together
This may sound unbelievable, but it is true. Two pieces of metal without any coating on them will form in to one piece in the vacuum of space. This doesn’t happen on earth because the atmosphere puts a layer of oxidized material between the surfaces. This might seem like it would be a big problem on the space station but as most tools used there have come from earth, they are already coated with material. In fact, the only evidence of this seen so far has been in experiments designed to provoke the reaction. This process is called cold welding.
There are over 20 million observable meteors per day.

Out of these,only one or two meteorites per day reach the surface of Earth. The largest found meteorite was found in Hoba, Namibia. It weighed 60 tons. The typical size of a meteor is about one cubic centimeter, which is equivalent to the size of a sugar cube.Each day, Earth accumulate 10 to 100 tons of material.
You might be thinking if the above fact is true,then what is all the fuss about 'rocks' hitting the earth?
Those are asteroids.The most dangerous asteroids, those capable of causing major regional or global disasters, usually impact the Earth only once every 100,000 years on average. Some large asteroids even have their own moon. The orbits of most asteroids lie partially between the orbits of Mars and Jupiter.
 In space, any free moving liquid will form itself into a sphere.
This happens due to surface tension.The liquid tends to acquire minimum possible surface area  for its volume.

 If you shouted in space quite literally no one could hear you scream – even if they were standing/floating right next to you.
The reason for this is the absence of atmosphere or one should say a medium for the sound waves to travel.

If you fold a piece of A4 paper in half 44 times it will reach the moon
If a piece of paper is 0.1mm thick,then the effective thickness doubles on folding.Thus on folding 44 times it will be 2^44 times which is then multiplied by 0.1mm which gives 1.76 million kilometers.

Proving that women love to do things differently, Venus is the only planet to rotate clockwise.
When Apollo 11’s lunar module touched down on the moon, it had just 20 seconds of fuel left on board.

How it Should have ended?

Film makers tend to look over some very simple and straight forward ways of 'doing the job' and make it complicated because thats how we like it.
But will we like it if it was done the easier way?
Watch the following videos and decide for yourself.

You just got to agree with this one.

Well the numbers may not win you the war but they sure give you an advantage.

Don't just trim the leaves of a weed,absolutely root it out.

Woah the film revisited all 3 parts in 6 minutes !

Captain Jack Sparrow continues to take over the clip even here leaving Mr Bloom look like a sidekick in another epic.

All the 'Twilight lovers' and 'The twilight lovers' would have a say on this.

Recover Lost Data

Accidentally deleted an important file? Lost something important when your computer crashed?

Well don't worry there are ways to recover the lost data if:

  • It hasn't been written over with new data on the disc---When your operating system deletes a file, all it really does is mark the space on your hard drive that your file occupies as free space. It's still there, but your computer is now perfectly happy to write new data on top of it—at which point the file recovery process becomes a lot more difficult.

  • If you formatted your computer and did it with a different file system type,the recovery is going to be a whole lot more difficult.

If you are using Windows,there are a lot of options available as free file recovery programs.
 Recuva is a cool option.

MAC users might have to spend a few bucks and get  Data Rescue II .

You might want to take a look at the following as well.

If you are using Windows 7  or Windows Vista Ultimate/Business/Enterprise editions ,then the shadow copy feature provided by them may come to your rescue.
Shadow copy  creates copies on a scheduled basis of files that have changed.

To access this feature,all you have to do is right click on the file/folder and select "Restore previous versions."What it does is that it lets you see the file as it was some time ago and thus helps to restore it by just dragging it to the desired folder and selecting 'restore' or just click restore if you want it to go to the original location.

Curiosity killed the cat

Ever felt curious?
Wanting to do the things that you are told not to?
Well you are no different ...

Do not press?I wasn't going to but you just had to write that ,didn't you?

Hmmm,let's see what's the worst thing that can happen if the finger is inserted?Yeah,the finger might be lost.
But if he doesn't insert the finger,he can die of curiosity.

No matter what the species,men will be men.

Who the hell writes about that?

This time around,no matter how old,men will be men.

Valid Point!

Not exactly a curiosity demonstration but surely a curious thing.

Now there are many better things to do than scraping off ice,aren't there?

Who doesn't like comfort?

Job well done!

Should I pick up the thing?That's not my job!

Save your energy for the real work at the right place.

Don't tell me you have not seen this at a place near you.Part 2.

Some medium level problems on SPOJ

Here are some of the medium level problems on SPOJ:

1. Prime Generater – This question can be solved by applying sieve’s algorithm. What we do is make an array of prime numbers in the range of 1 to 32000 ( square root of 1000000000 ) .. now we have our initial setup ready .. for generating primes i used sieve’s algorithm which states that you make an boolean array of 32000 values and initialize it as true that means declare all of them as prime .. now start from 2 and if the current number is prime .. make all itz multiple in the apropriate range as composite ( i.e. set their index in the array as false .. ) .. this is the fastest method for generating prime numbers .. now we start taking the input from the user .. lets say he gives the numbers m and n as input ( m> n) now we apply sieve again .. first make an array of booleans of size m-n ….. now for all the prime numbers from 2 to the prime number next to the square root of m we make their multiples in the range n to m as composite ( i.e. set their array as false ) .. now after this procedure is over .. just a linear traversal in the second array .. and print whatever is prime .. ( i.e. flag is true .. ) .

2. Small Factorial .. – This is fairly simple problem .. you just have to make a programme to multiply arbitrary large numbers . ( stored as strings .. ) and then run a loop from 1 to n to calculate the answer .. thats it ..

3. Bytlandian cryptographer .. act 2nd .. – This is again a very easy problem .. add 1 to a number isnt it easy !!!! .. but the problem is you have to write the code in Brainf*** yeah that language does not have even a multiplication and addition operators .. just 8 instructions and the language is over .. !!! :( .. but you can try the official documention of brainf*** language .. go through may be first page and thats it for this problem easy points once you go through this page ..

4.Bytelandian gold coins -This problem can be solved by recursion using the relation:
but it times out.The solution to that is memoization.It is a technique in which we store the already calculated results in a sort of cache and use it whenever needed instead of calculating it again.
here's a sample  for the same in C++:

map reference;

long long f(n)
   if(n==0)return 0;
   return reference[n];

5.POKER:Though its a very easy problem if you know the rules of POKER but i put it in medium because i think its very easy to miss any condition in this and  get it wrong.

Best Of Luck

Its sometimes pretty difficult to find the easy problems among the thousands on SPOJ.
Here are some of the problems on SPOJ that i found easy and that pretty must guarantees that they are easy.  :)

TEST- This is the first problem I solved in SPOJ. I recommend the same for you as it will introduce with the way of accepting input and printing output that SPOJ wants. It gives a brief introduction of the whole environment. What you need to do is to accept and print the input by the user until you come across 42. The easiest problem at SPOJ and a confidence booster to begin with..!! ;)

FASHION-The explanation is quite big but it all comes down to sorting the two lists of degree of hotness and then multiplying the corresponding numbers and adding them.pretty simple huh ;).

ADDREV-Take two numbers as input. Reverse both. Add the reversed number. Reverse again.

MIRRORED- Print "Mirrored pair" wherever you confront "bd" or "db" or "pq" or "qp", otherwise print "Ordinary pair"

OFORTUNE- The explanation is frightening and large.But the problem is really simple.It just needs six inputs and a simple interest and compound interest formula implementation .Due to the large explanation not many people have solved this you'll get a lot of points too.

FEYNMAN-If you observe for a while ,you will find that the answer is just the sum of the squares of the numbers 1 to N.

Some more easy problems are SIZECON ,NSTEPS,TABLES,JULKA,CANDY,CANDY 3

Best of Luck !

Getting Started with SPOJ...

SPOJ is the perfect place to practice coding in any language you matter how good or bad you are at will find problems for your level.

This is a quick how to begin on SPOJ:

The first thing you need to do is to register (it's free and spamless). Then find problem from one of the extensive problemsets, write a solution in your favorite language and submit it. Next switch to status page and watch progress of judging of your solution. After few moments you will see the result:
1. AC - accepted - your program ran successfully and gave a correct answer (this you will like most :) )

2. WA - wrong answer - your program ran successfully, but gave an incorrect answer

3. TLE - time limit exceeded - your program was compiled successfully, but it didn't stop before time limit
These are status codes you will see most often. To know all of them, see FAQ or this tutorial.

Once you get up and running,you get points for the problems you solve on the following basis:

  • for solving classical problem p: 80/(40+number_of_people_who_have_solved p) points
  • for a top score in any challenge: 3 points,
  • for any lower score in a challenge: (user's_score relative_to_the top_score) points.
Numbers given in brackets beside the scores correspond to the number of solved classical problems and the number of challenges for which the user's best score is also the top score, respectively.

Now check out your programming skills.For a start look at these for hints:

Albert Einstein Quotes

The genius was surely good with words.His sayings are perfectly relevant even today and most of them tend to tickle your funny bone,

Here are some of them:

"Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius -- and a lot of courage -- to move in the opposite direction."

"Imagination is more important than knowledge."

"Gravitation is not responsible for people falling in love."

"I want to know God's thoughts; the rest are details."

"The hardest thing in the world to understand is the income tax."

"Reality is merely an illusion, albeit a very persistent one."

"The only real valuable thing is intuition."

"A person starts to live when he can live outside himself."

"I am convinced that He (God) does not play dice."

"God is subtle but he is not malicious."

"Weakness of attitude becomes weakness of character."

"I never think of the future. It comes soon enough."

"The eternal mystery of the world is its comprehensibility."

"Sometimes one pays most for the things one gets for nothing."

"Science without religion is lame. Religion without science is blind."

"Anyone who has never made a mistake has never tried anything new."

"Great spirits have often encountered violent opposition from weak minds."

"Everything should be made as simple as possible, but not simpler."

"Common sense is the collection of prejudices acquired by age eighteen."

"Science is a wonderful thing if one does not have to earn one's living at it."

"The secret to creativity is knowing how to hide your sources."

"The only thing that interferes with my learning is my education."

"God does not care about our mathematical difficulties. He integrates empirically."

"The whole of science is nothing more than a refinement of everyday thinking."

"Technological progress is like an axe in the hands of a pathological criminal."

"Peace cannot be kept by force. It can only be achieved by understanding."

"The most incomprehensible thing about the world is that it is comprehensible."

"We can't solve problems by using the same kind of thinking we used when we created them."

"Education is what remains after one has forgotten everything he learned in school."

"The important thing is not to stop questioning. Curiosity has its own reason for existing."

"Do not worry about your difficulties in Mathematics. I can assure you mine are still greater."

"Equations are more important to me, because politics is for the present, but an equation is something for eternity."

"If A is a success in life, then A equals x plus y plus z. Work is x; y is play; and z is keeping your mouth shut."

"Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe."

"As far as the laws of mathematics refer to reality, they are not certain, as far as they are certain, they do not refer to reality."

"Whoever undertakes to set himself up as a judge of Truth and Knowledge is shipwrecked by the laughter of the gods."

"I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones."

"In order to form an immaculate member of a flock of sheep one must, above all, be a sheep."

"The fear of death is the most unjustified of all fears, for there's no risk of accident for someone who's dead."

"Too many of us look upon Americans as dollar chasers. This is a cruel libel, even if it is reiterated thoughtlessly by the Americans themselves."

"Heroism on command, senseless violence, and all the loathsome nonsense that goes by the name of patriotism -- how passionately I hate them!"

"No, this trick won't work...How on earth are you ever going to explain in terms of chemistry and physics so important a biological phenomenon as first love?"

"My religion consists of a humble admiration of the illimitable superior spirit who reveals himself in the slight details we are able to perceive with our frail and feeble mind."

"Yes, we have to divide up our time like that, between our politics and our equations. But to me our equations are far more important, for politics are only a matter of present concern. A mathematical equation stands forever."

"The release of atom power has changed everything except our way of thinking...the solution to this problem lies in the heart of mankind. If only I had known, I should have become a watchmaker."

"Great spirits have always found violent opposition from mediocrities. The latter cannot understand it when a man does not thoughtlessly submit to hereditary prejudices but honestly and courageously uses his intelligence."

"The most beautiful thing we can experience is the mysterious. It is the source of all true art and all science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed."

"A man's ethical behavior should be based effectually on sympathy, education, and social ties; no religious basis is necessary. Man would indeeded be in a poor way if he had to be restrained by fear of punishment and hope of reward after death."

"The further the spiritual evolution of mankind advances, the more certain it seems to me that the path to genuine religiosity does not lie through the fear of life, and the fear of death, and blind faith, but through striving after rational knowledge."

"Now he has departed from this strange world a little ahead of me. That means nothing. People like us, who believe in physics, know that the distinction between past, present, and future is only a stubbornly persistent illusion."

"You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat."

"One had to cram all this stuff into one's mind for the examinations, whether one liked it or not. This coercion had such a deterring effect on me that, after I had passed the final examination, I found the consideration of any scientific problems distasteful to me for an entire year."

" of the strongest motives that lead men to art and science is escape from everyday life with its painful crudity and hopeless dreariness, from the fetters of one's own ever-shifting desires. A finely tempered nature longs to escape from the personal life into the world of objective perception and thought."

"He who joyfully marches to music rank and file, has already earned my contempt. He has been given a large brain by mistake, since for him the spinal cord would surely suffice. This disgrace to civilization should be done away with at once. Heroism at command, how violently I hate all this, how despicable and ignoble war is; I would rather be torn to shreds than be a part of so base an action. It is my conviction that killing under the cloak of war is nothing but an act of murder."

"A human being is a part of a whole, called by us _universe_, a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest... a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty."

"Not everything that counts can be counted, and not everything that can be counted counts."

LOTR Would Have Been Completely Different If:

I am a big fan of the Lord of The Rings and just love its storyline,its representation and its grandeur.I have my favorite moments from the trilogy as have been quoted
here as well.

Here's a little piece on how a few lines by the characters of the epic by J.R.R Tolkien could have completely changed the story line.

Frodo: "You mean you summoned Eagles to carry you off of Saruman's tower?"
Gandalf: "Yes".
Frodo: "So why not summon them to carry me to Mount Doom? If we walk all the way there one of us may die."

Gandalf (to the Balrog): "You may pass if you wish."

Elrond:“Sorry, Isuldur, we’ve spilled too much blood for you to go muck it all up with a momentary fit of self-delusion. Either that ring goes into the fire or both of you do.”

Sauron :"Let's see, we have quite enough orcs to wipe out Gondor.Witch-King why don't you just put a few hundred by the mountain,just in case"

Sam: "Please mister Frodo, I know I'm being subjective and I'm not making myself out to be a detective but I can't trust that hideous slimy bastard.His teeth are disgusting and I don't like his hobbling and hissing.So I have a proposition, put simply:Cage Match, no DQs, him and me."

Pippin: "All right Treebeard,great job with Isengard.But it's still not the time to relax,just gather your tree friends and we are going to Gondor.Let's finish this thing."

Sam : "Frodo,you know as well as I do that you are becoming way too attached to the ring.Let's not wear it from now on.Keep it in the bag and we can take turns with it,I am not going to run away with it."  

Frodo: "Hey Sam, I'm heading off to Aman to lead an eternal life of bliss. You are my best friend, and basically carried my punk ass up Mount Doom and all... Alright fine, you can come, but just this once."

Faramir: "Frodo, I have heard terrible stories about Cirith Ungol.But if you insist you need to go that way ,me and my friends here would love to help you to the place.Anyways my father doesn't give a damn if i live or die."

Witch-King: "I got an idea.Lets not just screech like hell and scare them but jump into the battle field and do some real serious damage."
