More fun with Zero

It seems that zero is not a real number, because the word "zero" has no referent.
"1", "2", "pie", "square root of two" and "-.026" - Each of these refers to one of a class of metaphysical objects whose members include all and only those quantities on a continuum between nothing and infinity (negative numbers are positive quantities with negative direction). Like infinity, zero marks one end of the conceivable quantity spectrum.
Should the book ends be called books? Or are zero and infinity limits of the set, and not to be included in it?
Mathematicians say that zero is a real number, but infinity is not. What is their reasoning for this?

You should review the number line.

I always thought about stuff like this sitting in all those calc classes... In one way, yes, zero is a number. But if its being used as a limit on things (like if youre looking at it from 0->inf), then it doesnt really exist... you cant ever get there, but you can get infinitely close to it. However, if you think about it as all numbers exist between negative infinity and infinity, then zero would be another number just like -9 or 5 or 2. But saying it the way you do, like -9 is just 9 going the other direction, you can say 0-inf are the only real numbers, and since 0 doesnt have a negative it may not be real, but it is defined. Infinity is undefined.
Therefore Ill say it's real since its definable, but Ill also say you could argue the other way just as easily and Id probably agree with you as well.

Nice post! I used to think about this sometimes, whether 0 was a real number or an imaginary number.

It's all of matter of definition. Historically, zero has meant the lack of any quantity. If you're referring to numbers as being points on a number line, then yes - zero is a number.

The word "zero" is definable, and so has meaning or semantic weight, but , by definition, it refers to nothing, and therefore lacks a referent.
One could say certainly say that 0 refers a point on a number line, or the origin in a Cartesian coordinate system, but a continuum from negative infinity to positive infinity is really just two continuums butted up against each other, something akin to a ball falling toward the floor and bouncing back in the opposite direction. The ball's, acceleration changes signs from positive to negative but its motion is never less than no motion.

I totally understand that, and do agree.
Also, when you bounce a ball, it never actually touches the ground... it just gets infinitely close. Same with everything else in the world (I would explain, but its been a few years since physics, and I dont want to say something stupid in the explaination... BUT it does make sense when explained, and it is true). Therefore, youre also right... 0 cannot be reached whatsoever.
Im not entirely sure, but i think the ball does stop for an instant tho... when it gets compressed right before it bounces back... all the energy is converted into kenetic energy as it compresses, and its spit back out again when it bounces back.

all zeros are not created equall, just as there are an infinite infinities

Wait, so how exactly does that work? When you bounce a ball, doesn't it have to touch the ground to bounce?

it does... its down at a molecular lvl where the charges or something repel the other object away from it, so they never touch. If they did touch, theyd fuse together.

is it a zong? thats what mine was. anyway, sorry for going off topic guys!
so i guess that's why different material don't bounce? do they not charge enough at the molecular level or something?

But what exactly is an empty set?
Mathematicians have hypostasized nothing by drawing brackets around it.

A set with nothing in it... like a bookshelf without any books on it.
Zero as an empty set I can understand. Zero as a number, I cannot fathom.

infinity = everything
the number 3 = something
so the number 3 = infinity
the number 4 = something
so the number 4 = infinity
something = something
infinity = infinity
3=4

Constructing surreal numbers
The basic idea behind the construction of surreal numbers is similar to Dedekind cuts. We construct new numbers by representing them with two sets of numbers, L and R, that approximate the new number; the set L contains a set of numbers below the new number and the set R contains a set of numbers above the new number. We will write such an approximation as { L | R }. We will pose no restrictions upon L and R except that each of the numbers in L should be smaller than any number in R. For example, { {1, 2} | {5, 8} } is a valid construction of a certain number between 2 and 5. (Which number exactly and why will be explained later on.) The sets are explicitly allowed to be empty. The informal interpretation of a pair { L | { } } will be "a number higher than any number in L", and of { { } | R } "a number lower than any number in R". This leads to the rule:
http://en.wikipedia.org/wiki/Surreal_numbers
but back to what i was saying
there are many zeros and and they are not all equal
just as the real numbers fill in the holes of the integers, there are yet other numbers (surreal for example) that fill in the real numbers
the real numbers seem solid, but there are holes, rather large ones
these holes are especially big when it comes to infinity and zero

This reminds me of a documentary about four mathematicians that did groundbreaking work, but suffered severely from all the paradoxes and new questions that emerged.

excellent video ! 
adjust: You mean there are different 'strong' zeros, like there are different 'big' infinities ?
I also see zero as a placeholder. Like nothingness gives possibility to something, zero gives room for numbers. The interesting thing is, that zero looses all relations for what it stands when it becomes zero (zero cows, zero water, zero trees,... all the same zero ?) An eliminator and the foundation of existence (by giving room to something) at the same time ?

Zero indicates what remains when all things are gone. That make's zero a paradox. Something to represent nothing is not nothing. But that's just talk...
Zero is just an indication for the total absence of all things. Infinity would then be just plain all!
