The worlds biggest chin vs. the worlds biggest forehead. Go figure...

[Arcadian Daze]

i cant see how that's a paradox in any way

[Hostile]

Well it could have been two big chins or two big foreheads, instead it was one of each, I find that amazingly paradoxical.

Fox News. I find it paradoxical that anything they say could be considered news by anyone. Well, maybe less paradoxical and more... just plain wrong.

Also, Zeno's Achilles-tortoise and arrow paradoxes. They're the real deal.

arrow paradox?
i dont know that one tell me please

If a crocodile steals a child and promises its return if the father can correctly guess what the crocodile will do, how should the crocodile respond in the case that the father guesses that the child will not be returned?

and of course the double paradox of the haning man;

A judge tells a condemned prisoner that he will be hanged at noon on one weekday in the following week but that the execution will be a surprise to the prisoner. He will not know the day of the hanging until the executioner knocks on his cell door at noon that day. Having reflected on his sentence, the prisoner draws the conclusion that he will escape from the hanging. His reasoning is in several parts. He begins by concluding that the "surprise hanging" can't be on a Friday, as if he hasn't been hanged by Thursday, there is only one day left - and so it won't be a surprise if he's hanged on a Friday. Since the judge's sentence stipulated that the hanging would be a surprise to him, he concludes it cannot occur on Friday. He then reasons that the surprise hanging cannot be on Thursday either, because Friday has already been eliminated and if he hasn't been hanged by Wednesday night, the hanging must occur on Thursday, making a Thursday hanging not a surprise either. By similar reasoning he concludes that the hanging can also not occur on Wednesday, Tuesday or Monday. Joyfully he retires to his cell confident that the hanging will not occur at all. The next week, the executioner knocks on the prisoner's door at noon on Wednesday — which, despite all the above, will still be an utter surprise to him. Everything the judge said has come true.

The arrow paradox works by blank logic in the face of reason. Aristotle once said "If everything when it occupies an equal space is at rest, and if that which is in locomotion is always occupying such a space at any moment, the flying arrow is therefore motionless." This was said after Zeno conjectured that if, at any moment, the arrow is stationary, it must therefore transfer to another point in space instantly and without the passage of time. Basically, in any instant of time there is no motion occurring because an instant is like a screenshot, a single moment captured. Therefore, if the arrow cannot move in a single instant, it cannot move in any instant, thus rendering motion impossible.

[some_weirdGuy]

except even in logic that fails as you don't measure movement in an instant. The very definition of movement is the change of position for an object between atleast TWO instants(or, over time). not 'the instantaneous relocation of an object'.

I'd say your thing is hardly paradoxical at all.
proper paradoxes are like the one i have said before:
(the below is said by a person who either always lies, or always tells the truth[otherwise the paradox doesn't work ])
"i always lie"
is the person telling a lie, or the truth?

Of course you don't measure movement in an instant, you pillock. But let me put this in more idiot-proof terms: if you take a photograph of something, you have captured a single moment in time. If you take a photograph of an arrow being shot through the air, the arrow will not be moving in the picture. If you take a picture of the same arrow a tiny fraction of a second later, it will no longer be in the same place. You, sir, are clearly no logician.

[Arcadian Daze]

the "i always lie" paradox isnt really a paradox
its jsut a phrase of funny things that cant be solved and have no logic involved
real ones like the arrows and the tirangle are diffucult ones competing with logic
heap paradox;
since there is no exact number of how many object you need to form a heap(its not that 37 grans of sand is a heap and 36 isnt) you can make heaps as small as oyu want
for instance 1 grain of sand isnt a heap. you cant argue about that
2 still isnt, but if you take 1 million grains you have a heap without doubt.
take one away and its still a heap because a heap doesnt consit of a set number of objects
now that we know that you can take away 999,998 more grains of sand away and you'll still have a heap because of the number thats not set.

and one wich is hard to explain in words
as i assume you all know the saying of phytagoras wich goes; a2 + b2=c2
you can put anopther triangle on top of it and it would still fit with the saying
also the same goes for 2 triangles of half the size of the main one
if you continue to make them smaller and smaller you could make a staight line and at that point its not a2+b2=c2, but a+b=c

maybe this(bad drawed by me) pictue will help a little
my english is not good so if oyu cant understand it ill try to clear it up a little bit

There are two in my signature. See if you can spot them.

Boooo! Poor effot!

[Ash]

I thought that was quite witty, myself.

[Vortigern]

I'd have to go with Olli on this one, mate. You know you can do better!

[Bart]

Actually the triangle thing is incorrect. No matter how small you make the step, they still remain jagged stairs and not a single straight line. It might appear as such, but if you zoom in the steps will come back.

[Phil]

Just make them infinitely small

Ok, i don't get what you are trying to say, as how does this in any way contradict what i said? Or prove that your original post is a paradox? I'm still not seeing whats so paradoxical about the whole thing.

But then again i'm smart enough to know how movement works, maybe only people who don't know how it works would be confused and see paradoxes in what you originally said.

(I take what you originally said to mean: an arrows motion in 1 instant = 0, so it can never move cause its movement in an instant is always 0 and 0 + 0 etc is still 0. To which i said that doesn't work cause you don't measure movement in one instant making that all wrong)

Oh and when you take a photo, you don't measure an instant, but an interval. Most of the time this interval is so small you can't see the movement, but often it also is not:
