My problem with infinity
-
Which infinity? There are many.[^]

That's just too deep for a Sunday!

I've counted till infinity. Cheers, Chuck.

In non-scientific terms, such a situation is a paradox. In scientific terms, such a situation cannot exist. :rolleyes:
There are only 10 types of people in this world — those who understand binary, and those who don't.
Correct. :)

Woken up plagued by the concept of infinity again. Precursor to a difficult day ahead methinks. Infinity in my mind is that place you never get to. Try counting to infinity and you won't get there. Purists might argue that you would if you spent an infinite amount of time counting. But, seemingly we do get there. The abstraction I have in my head is this: A clock face with a straight line through it, going straight through the 6 and 12 and extending where else, but to infinity. Draw another parallel line to the left of the clock. Then, when the hour hand is on the 9 it points to the nearest point on the second line. As time progresses, the point on the second line moves up, heading straight for infinity. Now by rights, it should never get there, but it does, 3 hours later. It got there I believe at 3 hours - (1/infinity). It's a theoretical place, but it's also real because we just went through it to get to midday. So, where is it? I've expressed my concerns to my wife but she just gives me that slightly desperate lonely look. Oh dear, deep questions about the Universe always leave me feeling edgy.

That is a contradiction in terms. Infinity is by definition unreachable...

Seems to me you delved into the concept of an asymptote.

As others have stated, you sadly stumbled on (over?) a singularity point. Shame though, many of us would attest to having empirical evidence supporting your theory: 3 hours = (1/infinity) => infinity = 1/3 hours = 20 minutes - mind you in the (in)appropriate context.

Infinity is not a number therefore by trying to represent it with numbers you are doomed.

how can there be an edge? there is more space beyond......
<geek mode> The latest thinking is that space is finite in three dimensions. Four dimensional space-time is collapsed into a finite three-dimensional volume by the effect of gravity. As an example, concrete over the whole world (ignore the environmental impact for now), and then smooth out all the mountains with a really big bit of sandpaper. The surface of the earth (a two dimensional object) is finite (in three dimensions) but has no edges. Now exapnd that concept from a two-dimensional object in the three dimensions into a three-dimensional object in a four dimensions. </geek mode>

There's the rub! That's where our spatial, or solids, models of perception break down.

You *can* reach infinity by counting - you just have to e.g. permanently double your speed. :cool: Is "Horizon" an equally complicated concept for you?

Hi Rob, Both Cantor and Godel went insane working on the problem of the "Aleph," or the ordinality of infinities : careful, there. I like Blaise Pascal's words : "A fearful sphere whose center is everywhere, and circumference is nowhere." Jorge Borges, one of my favorite writers, traces the origins of that metaphor from ancient Greek times, up through the middle ages, in one of his best known essays (citation on request : note the word 'fearful' was first used in a 1941 scholarly translation that, for the first time, accurately included and translated the French word "effroyable" (fearful) : whereas earlier translations/editions rendered the quote starting with "Nature is a sphere ..."). best, Bill
"Many : not conversant with mathematical studies, imagine that because it [the Analytical Engine] is to give results in numerical notation, its processes must consequently be arithmetical, numerical, rather than algebraical and analytical. This is an error. The engine can arrange and combine numerical quantities as if they were letters or any other general symbols; and it fact it might bring out its results in algebraical notation, were provisions made accordingly." Ada, Countess Lovelace, 1844

But that's just convention - arguably a sensible one. But Troll is right (something you read only on CP...) - infinity is not on that line, and it sems to me you are still looking for it there.

Not at all. There are at least two infinities on every straight line, so we'll never run out of infinities. Unless you start claiming there is no such thing as a straight line... :)

That is not infinity, that is undefined. If you replace the 0 with an x, you can argue about what happens once x creeps closer to 0, but that's about it.

Sorry Josh, but you sometimes end up quite elusive. Can I take a CPhog issue to Web Development, or can I email you?
