Great fact about mathematics!!

You will never look at a deck of cards the same way after reading this.

How many ways can a deck of cards be arranged?

Any mathematician will tell you that it’s a simple calculation - the answer is

52!

But how big is this number really?

52 Factorial has found a creative way to visualize this number. I have simplified it for better readability.

Set a timer so that it would take $52!$ seconds for it to reach 0.

Choose any spot on the equator. You have to walk around the Earth along the equator. But there’s a the catch — you can only take one step every billion years.

(Did I leave the stove on?)

After you complete one journey around the equator and reach the point where you started, remove one drop of water from the Pacific Ocean.

(No peeking at the timer!)

Now repeat the whole process — walk around the Earth at one billion years per step, removing one drop of water from the Pacific Ocean every time you circle the globe. Continue until the ocean is empty.

(How long has it been?!)

After you have emptied the Pacific Ocean, take one sheet of paper and place it flat on the ground.

Fill the ocean back up and start the entire process all over again, adding a sheet of paper to the stack every time you empty the ocean.

Do this until the stack of paper reaches the Sun.

(You’re almost there!)

Once the stack reaches the Sun take it down and do it all over again.

One thousand times more.

(Is there a point to this?)

Surely the timer must have reached 0 by now?

Nope.

You’re only done with one-third of the time!

Now you can imagine how big 52! really is.

MIND = BLOWN

*52! = 52 * 51 * 50 … 3 * 2 * 1

Audiobook of the week

Braving the wilderness ‘True belonging doesn't require us to change who we are. It requires us to be who we are.’ Social scientist Brené Brown, PhD, LMSW has sparked a global conversation about the experiences that bring meaning to our lives – experiences of courage, vulnerability, love, belonging, shame and empathy. In Braving the Wilderness , Brown redefines what it means to truly belong in an age of increased polarisation. With her trademark mix of research, storytelling and honesty, Brown will again change the cultural conversation while mapping out a clear path to true belonging.

3n+1 conjecture!!!?? What is it?? This will make you think really hard.

Let's start with a game. Think of a positive number (say n). If it is even then replace it with it's half (n/2). If it's odd then replace it with three times of itself plus one (3n+1). for e.g., let's take 15. since its odd, so it becomes 15*3+1 i.e., 46 now 46 changes to 46/2 i.e., 23 agin 23 changes to 23*3+1 i.e., 70 continuing this we get a sereis.... 15,46,23,70,35,106,53,160,80,40,20,10,5,16,8,4,2,1.....---> so this continues. You would be thinking, this is not hard.....Beacause it's not the problem. The problem is that if you start with any of the positive number eventually it ends up with 1. Try with some numbers like 11 - 11,34,17,52,26,13,40,20,10,5,16,8,4,2,1 7 - 7,22,11,34,17,52,26,13,40,20,10,5,16,8,4,2,1 13 - 13,40,20,10,5,16,8,4,2,1 This problem drives mathematicians crazy because there don't seems to be any clear pattern. There are certain amazing numbers like 8192 that collapse down to 1 very quickly i.e in only 13 step...
