An infinitely large set is a conceptual piece of data that can never exist in its entirety.

What is "infinity"?

Name: Anonymous 2012-09-25 16:02

is there a set which has a cardinality between that of the natural numbers and that of the continuum?

Name: FFP 2012-09-25 16:07

Infinite is that which has no end.

Sets are defined as collections of elements, not as nothings.

An empty element is an element that is 0.

Not a set anymore. The absence of anything is not a collection of elements.

Somebody step up and properly define ``Set'' and ``Empty set''.

No. Just because you haven't finished your first year of CS.

A set is a collection of distinct elements. An empty set is a set that contains all those elements that are different from themselves.

"set" is jewish buzzword, just like "collection", "infinity" and "god".

Go troll someone else, the empty set has always been a set. It's guaranteed by the empty set axiom, which is a part of the canonical set theory.

>>15
I've heard this before, but don't understand. What about the empty string?

The empty element is the only element in the empty set.

That's not true. The empty string is not in fact a part of the empty set, as it has a value (empty).

Also, an empty element could be another empty set, i.e. {{}}

You misunderstood. An empty string is not the empty element. The empty element is the element defined by the very lack of an element.

Can't see your "empty set".

Name: Anonymous 2012-09-25 18:03

An empty set is a like an empty box of goods.

The box is there, and it doesn't have anything inside, but it's there. You can't say "there are no goods so the box disappeared".

On the other hand, you can't have an infinite set, leave that to the Jews.

what if a set has one infinite element?

Then it also has infinite one elements, by definition.

Define 'infinite' as a descriptor for a single element that can be contained within a set.

Math theory involves solving problems like finding patterns in prime numbers, topology and thinking about the different kinds of infinity.

Empty set of empty boxes? If you put empty boxes inside a bigger box, it's not empty anymore.

Well, it's like that in Jewish set theory too. A set with empty sets ``inside'' is not an empty set.

Math is exactly like cooking: just follow the recipe. Symbols look confusing? Can't figure out how to solve a problem? All I hear is, "Waaah! Boo-hoo! I didn't read the introduction to the chapter that tells me exactly how to solve this generic category of problems!"
Maybe if you stop at calculus. Math isn't "following directions." That's being a human calculator. This guy is an idiot.

How is it not? Everything is rigorously well defined. You see an arrangement of symbols, you perform a sequence of tasks. Even ``figuring things out'' has a method to it.
