Hey, I thought it would be a fun game. The objective is to or to describe a manner to disprove the statement.

Disprove: Once someone leaves your sight, they cease to exist.

This could go into a lengthly discussion,

theres always another view, however i dont think this is the place to go into quantum theory n all that

tis like saying, 'if a tree falls in a deserted forest, does it make a sound?'

Of course it f***ing does

actually, it doesn't, look in the dictionary at what "sound" means.

You could put this the other way. If you go out of somebodies way, do u cease to exist?

No. It works the other way around too.

lets establish some terms here.
true person= the person who always exists
fake = someone who disapears


so if your the real person and you leave a fake's view you do not disapear because the other person is a fake and the statement only applies to the real person. so you are the only one this applys to.[/list]

I have another one. 0/0 = 0

no, division by 0 is undefined and currently a null set Ø

> Disprove: Once someone leaves your sight, they cease to exist.

If they ceased to exist when leaving your sight, you would have to have them re-exist every time they re-enter your sight. Since memories are carried over between sightings, it is obvious that these memories have not ceased to exist and therefore when someone leaves your sight they couldn't possibly cease to exist.

> if a tree falls in a deserted forest, does it make a sound?'

This would require sounds to exist in the first place. Sound, as conceptualized by human beings are simply vibrational waves occurring within earth's atmosphere (not making any sounds). When these vibrational waves hit the eardrum, it creates an electrical signal picked up and passed to the human brain (still no sound). The electrical signal is translated into an experience of hearing (but not a true representation of reality). This also goes for vision, it could be said that nothing you see is actually what you think you see, it is only a translated experience presented by your brain... an interpretation of the reality we think is physical.

This is a round about way of saying, sound is a human quality, and therefore, if there are no humans to experience the sound, then there is no sound. There are similar experiences for other trees, plants, bugs, rocks and other bodies in nature who will each experience the waves, but in different ways than our experience termed "sound".

> I have another one. 0/0 = 0

for any non-zero number.
0/n equals zero.
n/0 equals positive or negative infinity.
n/n equals one.

for n=0, all of the above are true, and hence the undefined state.

------------------------------------------

I have two problems.

n/0= undefined, 1/0= undefined

and lets say 0/0=x so multiply each side by zero and, it is 0=0x what can x equal? any number from negative infinity to positive infinity.

people gave a new name for that so x=nullity or 0/0=nullity

What's the problem? I agree with your statement. "0 = 0n" Is just another indication that 0/0 is undefinable. Thanks for pointing that out.

u r wrong

undefinable means there is no answer but nullity means, as I said in my post is negative infinity all the way through positive infinity

I disagree... undefinable means it is not defined.

undefined: not precisely limited, determined, or distinguished; "an undefined term";

And like all undefined terms, you are welcome to define it if you like. In your case, you defined it as negative infinity through positive infinity (all real numbers, including rational and irrational numbers). I would say all complex numbers (which includes both real and imaginary numbers) and transcendental numbers (real or complex numbers which are not algebraic). I would go so far as to include the alphabet and all other symbols or combinations of symbols, since 0/0 = CAT is valid if we defined it that way, considering sequences of numbers are simply symbols as well.

this is the meaning of undefined from a dictionary (the second one) I din't choose the first one because it didn't have to do with math.

Undefined: not given meaning or significance, as by a definition; not defined or explained: an undefined term.

as this says, it is impossible to tell what the answer is or, there is no answer. As for the other stuff you said, im not far enough into math to know about that type of math.

> Undefined: not given meaning or significance, as by a definition; not defined or explained: an undefined term.

How does that say "it is impossible to tell what the answer is or, there is no answer". What it says is that it is "not given meaning or explained", so it is simply a matter of personally defining it--which doesn't sound impossible to me.
