Gravity (The movie) - A marvellous experience

Plot - Two astronauts are stranded in space after a storm of space debris destroys their space craft. The debris is created by the chain reaction, occurred as a result of Russia destroying one of it's old satellites.
The story revolves around how the astronauts plan their way back to earth, in an acute shortage of life-sustaining resources.

The film has SCIENCE, WILDERNESS, PHYSICS REVISION, PHILOSOPHY, SACRIFICE and COURAGE in it.

I am writing this for those who have watched the film already. So don't expect me to tell the story.

The parts I liked the most was when the debris destroys the structures and the pieces of shrapnel come right towards you. ( Watched it in 3D, folks)

Around 7-8 times I tried to jerk my head back, to avoid the debris hitting me in the head with bullet speed.

One more scene that I liked was, when Ryan (Sandra Bullock) lies in the ISS escape probe ready to die in silence. But she hallucinates about Matt ( George Clooney) coming inside and asking her the question, "You lost your child. That's a pretty bad thing. So the point is- Is it worth living or just stay here and die silently? because that is also nice."

Also I find the death of Matt, quite interesting. I mean, how would it feel when you are going in a total void of space with no hope at all and you are constantly trying to encourage your fellow mate who may live.

Matt just about to leave his last hope (the rope), in order to increase chances of Ryan's survival.

It would be a great death. Watching the serenity of earth from outside after having achieved almost everything (he was a frequent astronaut, man!!!!), and doing a final act of sacrifice and still guiding your junior to life, and knowing that what a great impact, you would leave in her heart and your story will leave in rest of the world, while you die in absolute silence and peace.

AMAZING!!!!!

Nothing is Not NULL

Well, today's topic is 'nothing'. That doesn't mean, there is no topic. "Nothing" itself is the topic.

OK, I know that is quiet muddling, but believe me, this thing needs your attention.

This thought of 'nothingness' astonished me when I was wondering about the value of 'zero factorial', which is said to be 'one'.

Let's first get acquainted with the idea of 'Factorial':

If I have 4 balls (Green, Blue, Red, Yellow) and 1 dog (Cody) and I instruct Cody to bring all the balls, one by one. At first trip, Cody has 4 choices (Green, Blue, Red, Yellow). Let's assume, it brings 'Red' one first. At the second trip only 3 choices are left (Green, Blue, Yellow) and Cody grabs the Yellow one. Similarly, at the third trip only Green and Blue are there and it grabs the Blue one. Finally, with no choice left Cody gets the Green one.

So the order in which Cody brings the balls is: Red, Yellow, Blue, Green.
But how many, orders in which Cody gets the balls, are there??

It is quiet simple - 4 choices at first, then 3 choices, then 2 and lastly one.

Therefore the total number of cases are 4 x 3 x 2 x 1 = 4 factorial = 4 ! = 24. ( I hope you get that, otherwise you can always trouble your school teachers).
* '!' stands for factorial.

Let's say if there is only one ball. Then??
You are right...Only one case. And 1 factorial = 1! = 1.

Here comes the twist, there are no balls.
Now what ?? What are the number of orders in which the dog gets the balls.

Mathematically it's 0!, which is said to be 1.

Now what is this one case. This one case is the case of Cody coming back to me in a confused state, while wagging his tail, when it finds no balls over there. The case of getting no ball is itself a case.


When I came to realize this, it caused a paradigm shift in me.

Zero value or 'nothing' is an instance of an entity with zero magnitude
 but when an entity is not having any magnitude (not even zero ), then this itself is an instance of that entity having an uncertain magnitude or no instance at all. This can be termed as NULL.
We can say that in the equation 0! = 1, the '1' is not representing the magnitude, it is representing the presence of an instance with no magnitude.

Artwork (sort of)

This is a galaxy.

 

This is something related to science, think about it yourself

This is the reflection of my changing moods in a regular metro trip.

 

This is Electronics related.

 This is just something I don't know. It came out of my mind randomly.

That's it, I will post more afterwards.
