Where have you heard this?Originally posted by Thallium

I have heard that today's mathematicians are discussing what zero really is.

I guess this might help: http://members.aol.com/EgyptMaths/EgyptZero.htm and this http://reference.allrefer.com/encyclopedia/Z/zero.html, but I'm not really sure what you are trying to say about zeroOriginally posted by Thallium

There are two basic FACTS about zero.

1. for any number x, x + 0 = x

2. for any number x, x*0 = 0

.

Some people make a great fuss about limits involving zero. For example:

lim

lim

, but it won't work. The problem lies in the theory of limits, not in the meaning of zero.

I did not understand these symbols. What are these all about?Originally posted by quartodeciman

lim_{x->a}f(x)/g(x), where lim_{x->a}g(x)=0. They want to use as a general rule

lim_{x->a}f(x)/g(x) = lim_{x->a}f(x)/lim_{x->a}g(x)

, but it won't work. The problem lies in the theory of limits, not in the meaning of zero.

For me zero is the true balnced number and it represents the equilibrium point in my physics. You see zero has equal amount of positive and negative. On the other hand infinity is the point of extreme chaos.Originally posted by Thallium

Thank you!!

These are about functions and limits. I try to express in general terms what some people puzzle over specifically. For example: what happens to 1/x as x goes to 0. Well, you get 1/.1. 1/.01, 1/.001 and so on and these are 10, 100 1000 and so on. In view of this, many conclude that 1/0 is infinite. Other cases get more complicated.Originally posted by quartodeciman

It not the value that people find "special" it the idea of nothingness or the whole concept of nothingness as a value.. The NULL representation was invented by the INCAS thousands of years ago and has helped mankind ever since.

Sit on this: The most important numeric value to mankind has no numeric value.. Profound.. hey?
