Are you smart?

Socrates once said "I know one thing, that I know nothing"

Hello humans, Put on a helmet, because after reading this your mind may explode 😨 (just kidding).

I will be sharing with you some famous paradoxes that will hit your brain hard.

Let's begin 

1. Do you have a brother?

 

Consider a family, where there is a mother, father, and two children.

One of the children is a boy, then what are the chances of the second one being a girl. Is it 1/2, because the other children can be either a boy or a girl.

But, wait a minute...

 

There are four possible combinations of two children ( Boy, Boy), (Boy, Girl),(Girl, Boy) and (Girl, Girl).

Since one of the children is a boy, so the combination can not be (Girl, Girl), this means we are left with 3 possible combinations. This gives us the chances of the other children being a boy as 1/3.

Uhhh... this is confusing is it 1/2 or 1/3.

You tell me🤪

2. Crocodility

Once upon a time, a mother and a son visited a zoo. Accidentally, the son fell into a lake where there was a deadly Crocodile 🐊 , the crocodile snatched her son,

the mother begged to the crocodile to leave her son.

The crocodile was intelligent and kind but hungry also, he told the mother that he will ask her a question and if the mother gives the correct answer then he will leave her son.

Mother agreed,

Crocodile asked, "Will I Leave your Son?",

Now here is the catch, If the mother says "no", then if she is right and the crocodile never intended to return her child, then the crocodile has to return the son, but in doing so he breaks his own words and contradicts the mother's answer.

but if she was right, this means the crocodile intended to return her son, but since she is wrong, he will keep him.

This paradox is very famous and is often termed as "Crocodilite" or "Crocodility", to refer to the brain-twisting situations.

3. Galileo's Infinity Paradox

You know basic maths right?

Okay, 

We know there are Perfect Squares (like 1,4,9,16,...) and Non-Perfect Squares (like 2,3,5,7,...).

So, if we add both these sets, we get a larger set = Perfect + Non-Perfect Square numbers

This means the total number of Perfect squares is less than the total number of (Perfect + Non-perfect square numbers).

Easy bro!!!

No,

We no every number multiplied by itself forms a perfect square, this means the total number of perfect squares must be equal to the total number of numbers.

What's going on here?

4.  Why is everyone still?

This one drives me crazy every time I think of it.

consider a moving Car,

Now click its photo : 

What do you see? A still car, what does this show?

This shows the position of the car at the moment we clicked its photo. This means the moment at which we clicked the photo of the car it was still at that time, and every time we click its photo, we get the position of the car at that time.

Now if the car is still at every moment in time, then when does it move???

In fact, every moving body is still at every moment, then how does it appear to be moving

Think deep, you'll understand my point.

Thank you for being in this post with me🙏!

we'll meet in the next one.
