What is Paradox mean ?

The paradox is that the region's most dynamic economies have the most primitive financial systems.

Conditional statements in formal logic sometimes have counterintuitive interpretations, and the drinking paradox is a great example.

A paradox is a statement in which it seems that if one part of it is true, the other part of it cannot be true.

In fact, all it's saying is that it would be impossible for everyone in the bar to be drinking unless every single customer were drinking.

Therefore, there is at least one customer there (i.e., the last customer not drinking) who by drinking could make it so that everyone in the bar was drinking.

At first glance, the paradox suggests that one person is causing the rest of the bar to drink.

The pieces that the ball gets cut into are very strange-looking, and the paradox only works for an abstract, mathematical sphere:

It seems paradoxical: fewer miles driven wears out discs and pads more quickly.

As nice as it would be to take an apple, cut it up, and reassemble the pieces so you have an extra apple for your friend, physical balls made of matter can't be disassembled like a purely mathematical sphere.

Another surprising math result, the birthday paradox comes from a careful analysis of the probabilities involved.

To this layman's eyes, there is something paradoxical about it.

If two people are in a room together, then there's a 364/365 chance they do not have the same birthday (if we ignore leap years and assume that all birthdays are equally likely).

A paradox is a statement or problem that either appears to produce two entirely contradictory (yet possible) outcomes, or provides proof for something that goes against what we intuitively expect.

since there are 364 days that are different from the first person's birthday that can then be the second person's birthday.

If there are three people in the room, then the probability that they all have different birthdays is 364/365 x 363/365:

As above, once we know the first person's birthday, there are 364 choices of a different birthday for the second person, and this leaves 363 choices for the third person's birthday that are different from those two.

Paradoxes have been a central part of philosophical thinking for centuries, and are always ready to challenge our interpretation of otherwise simple situations, turning what we might think to be true on its head and presenting us with provably plausible situations that are in fact just as provably impossible.

Continuing in this fashion, once you hit 23 people, the probability that all 23 have different birthdays drops below 50%, and so the probability that at least two have the same birthday is better than even.

The Paradox of Achilles and the Tortoise is one of a number of theoretical discussions of movement put forward by the Greek philosopher Zeno of Elea in the 5th century BC.

The trick here is not to think of Zeno’s Achilles Paradox in terms of distances and races, but rather as an example of how any finite value can always be divided an infinite number of times, no matter how small its divisions might become.

The Bootstrap Paradox is a paradox of time travel that questions how something that is taken from the future and placed in the past could ever come into being in the first place.

It’s a common trope used by science fiction writers and has inspired plotlines in everything from Doctor Who to the Bill and Ted movies, but one of the most memorable and straightforward examples—by Professor David Toomey of the University of Massachusetts and used in his book The New Time Travellers—involves an author and his manuscript.

magine that a time traveller buys a copy of Hamlet from a bookstore, travels back in time to Elizabethan London, and hands the book to Shakespeare, who then copies it out and claims it as his own work.

Imagine you’re holding a postcard in your hand, on one side of which is written, “The statement on the other side of this card is true.” We’ll call that Statement A. Turn the card over, and the opposite side reads
