Warning: confusion might happen when reading this.
Anyway, today during math, the teacher was explaining that an object always wants to get to it's destination by cutting the distance in half. and again and again.
Now I asked: how can it ever reach it's destination if it always cuts in half?
Teacher: Now that is a like philosophy question. But what Socrates or other philosophic person did was take a dart and throw it against the wall. It did reach it's destination. Even if it always halfs it's distance.
Then I was thinking:
If it always halfs..or..Just makes it smaller in general like: 0,9 and then 0,99, then 0,999... and even 0,9999999999... It will go endlessly. So it's endless here. But if it's endless, it will never reach it's destination. But the dart did reach the wall. And yet math said: 0,9999 etc..
And I thought, But if it keeps going endless but still reaches the wall, doesn't that mean there is actually a limit? A point where the the line of 0,999999..just stops and turns into a 1?
Like:
0,99999999999999999999999999999*(limit/ wall) Bam!-> 1.
Then you might say, how can you compare the enviroment with math?
Well..Why not? If math is used to describe everything and to solve stuff. The enviroment is here as well. Like for example m² is area based.
Why can't we imagen a line of 0,99999..hitting an invisible or visible(wall) and then somehow turns into a 1?
One thing I also didn't get. The math sign: PI, an endless number, used in alot of formulas or excercises. But if you use something endless with another thing. How can it give a solution? It's endless.
So that means there is really a limit. Only we haven't found it yet.
-------------
I can go on like this and such..But just to ask, is what I was thinking all crap or do I make some sense here? :p and if yes, is it already stolen by someone? :p
Umm deep. ::) ::)
Way past my little brain.
Here is another one for you to think on.
Do two lines drawn parallel drawn to infinity ever touch?
Do they final join at their starting point making two parallel circles?
----------------------->
----------------------->
OO
Well, here is the flaw in the arguement.
The thing is 1/9 = 0.11111111111..... ie. 0.1 recuring
Then 2/9 = 0.2 recuring and 3/9 = 0.3 recuring etc.
So, 0.9 recuring, ie. 0.99999999999999999999999999999999999999999999999999999999999999999999999999999999....... is actually equal to 9/9 = 1
It is true that you can travel by continuously halving the distance, but each halving of the distance does not take the same amount of time. Assuming constant speed, the time taken for each step reduces according to a geometric pregression where the common ratio is 0.5 and the theory tells us that as long as the common ratio is less than 1, the sum of this infinite series will be a finite number.
Well, imo there is no infinity. As i said at my previous post :) What might be possible is that they do go straight ahead without touching eachother. But imo it can happen they will form a circle at a certain point but that means the straight line isn't completely straight.
But to get a complete perfect straight line is almost impossible.
Just like infinity..
See this as the line:
0,9999999999999999999999999999999 (almost perfect straight line but still a tiny flaw that will make a circle of itself at some point)
Which can be compared with the dart and the wall. Where is that missing piece that maked it 1?
The dart did reach it's point..But we don't know the destination of a line.. So 1 with a line =perfect straight. But perfection isn't possible according to math because it will keep adding a 9 to the enormous collection of 0,9999.. Yet closer to it. But not still not there.
But if the dart somehow could turn into a 1 to hit the wall (else it doesn't reach it) then so could the line. But how?
Hmm..Sounds interestign Akesha :o never thought math interests me like this x_x
Infinity is more of a concept than an actual number. Let me give you an example;
There are obviously fewer whole numbers, than there are actual numbers. Given any two whole numbers, 3 and 4 say, I can think of lots of other numbers which lie between them, like 3.1, 3. 5, 3.67 etc
Now, there are an infinite number of whole numbers, and an infinite number of numbers ... but, there are more numbers than there are whole numbers. Therefore we must conclude that some infinities are bigger than others, despite both being infinite.
To put it another way, it is possible to choose an infinite subset of an infinite set, meaning that if I have an infinite number of things to choose from, I can choose an infinite number of them, without choosing them all.
Hmm tough one.. But if we can keep adding numbers..How come 3 did go to 4? If there is an 'infinit' amount of numbers between 3 and 4 how come 4 does excist? Because 4 is the end of the 3 series and the beginning of the 4 series to 5.
Unless of course 4 can be put everywhere after 3. And that means we can decide when it's the end of 3?
Which means..We can keep adding stuff by free will. There is always a limit. But we humans keep making it longer by adding more numbers. But always after that comes 4.
Conclusion..There is no infinity..We only make the distance between 3 and 4 bigger. But there is always an end.
Edit: Did I just found something against infinity? :o
Oh and about 9/9. If you do 1/1 or 9/9 or 3/3 it's always 1. Because imo. If you (part?) somethign with itself, it will always leave a neutral part behind. Which is in this case 1?
....
Can ye eat et?
Greggar, don't start it with Akesha, Akesha actually -likes- math and makes a living out of it.. Crazy person...
And yes, Nergie.. Yer can eat et.
I agree with all of the above. ::)
How do i make my brain work over time even to read that lot. :-\ :-\

the distance between 3 and 4 remains fixed, we just chop it into very small pieces. think of it like a cake - you can chop it in half, then quarters.. with a large enough cake and a fine enough blade you could chop it into millionths or billionths. No matter how many pieces of cake you cut from a single cake, they will never amount to more than 1 cake, for more you need to get a second cake (mmm, cake :) )
Eventually with a cake you will be limited by physics - can you cut down to individual atoms? can you split quarks? With number theory you don't have these physical restrictions - you can split it down into an infinite number of parts which fit in the fixed 'space' between 3 and 4 simply because they are infinitely small.
Claws, in a theoretical sense, 2 parallel lines of infinite length should never meet. In the universe as we know it (or think we know it) we face the idea that space is curved by mass/gravity - even time gets messy. So I suppose 2 infinite parallel lines could be effected by gravity in diferent ways due to the distance between them and appear to curve, eventually meeting.
Typhek is absolutely right. What we have here is the principle of continuity. Another way to think about it is if you stick two very thin pins into a line. No matter how close together your two pins are, it is possible to stick a third pin in between them.
now I can harass my math teacher even more! yay! oh, and I thought I was good at maths... now I'm just depressed... ::)
Ahh but.
Curved Space:
The concept of a 'curved space', which is essential for present cosmological models, is logically flawed because space can only be defined by the distance between two objects, which is however by definition always given by a straight line. Mathematicians frequently try to illustrate the properties of 'curved space' through the example of a spherical (or otherwise curved) surface and the associated geometrical relationships. However, a surface is only a mathematical abstraction within the actual (3-dimensional) space and one can in fact connect any two points on the surface of a physical object through a straight line by drilling through it.
Strictly speaking, one can not assign any properties at all to space (or time) as these are the outer forms of existence and it makes as much sense to speak of a 'curved space' as of a 'blue space'. Any such properties must be restricted to objects existing within space and time.
The concept of a distorted space around massive physical objects for instance, as promoted by General Relativity, is therefore also inconsistent and should be replaced by appropriate physical theories describing the trajectories of particles and/or light near these objects.
:P :P
So There. ;)
I Blame Greggar for all this. ;)

Ah, the old relativist arguement promoted by Protagoras and the Sophists. You
know something when you perceive it to be true. Therefore all knowledge is merely perception and man is the measure of all things. However perception is mutable, different people can experience the same event in different ways. This leads the Sophists to the conclusion that all truth is subjective.
Plato however, rejected this idea. If truth is changable, then it becomes meaningless. How can you describe some thing as
white if everyone has a different idea of
whiteness? In such a world it becomes impossible to know anything.
Instead Plato argued that there are truths which lie at the centre of all things. We may argue about the nature of a particular truth, but that is because we perceive it imperfectly. Simply because we cannot agree on truth, does not mean that the truth does not exist. Our perceptions lead to beliefs and our beliefs give us a foundation on which to build our own experience of the nature of knowledge.
SHUT UP
My head hurts ;)

Good old Plato, I never liked him much :(. Very nicely written tho, the
idea is far better explained in your post than in the school books I had although it still doesn't answer this time's philosophy bomb. Plato could be wrong. *flops around helplessly*

All discussions end with Nazhra. For one simple reason: noone understand what she writes. that is fact. That is different then truth.
Doesn't change the fact that Kieth Jardine got KTFO by my man Wanderlei ;)
Ah, good old Pi. It does crop up in some surprising places. Sure it's all to do with circles, but when you think about it, there is something very fundamental about circles ... something that gets right to the heart of geometry and so right to the heart of how the universe works. It is true that it doesn't work well as a decimal, but then it does work as a fraction either, what with it being an irrational number and all.
Funny thing is, everyone assumes that the ancient Greeks called it Pi. It wasn't actually called that until relatively recently. It used to be called the Archimedian Constant, but that was a bit of a mouthful. Pie can be a bit of a mouthful too.

Now here's a strange thing ... today we regard numbers like Pi as deeply significant, but to the ancient mathematicians, one of the most important numbers was 153. Why 153? Well it is down to the idea of sacred geometry and the strange properties that the number 153 has.
For a start, 153 is a triangle number. Triangle numbers are got by adding consecutive whole numbers, the first being 1, then 1+2=3, 1+2+3=6, 1+2+3+4=10 etc. 153 is the sum of the numbers 1 to 17.
153 also has the strange property that it is also the sum of the cubes of it's digits. 1x1x1 + 5x5x5 + 3X3X3 = 153.
Most importantly, at the time of Pythagoras, 153 was part of the best known approximation of the square root of 3, 265/153. This number was important to the Pythagorean philosophers as being the vesica piscis, the measure of the fish. Now, if you arrange two equal circles so that the circumference of each one passes through the centre of the other, then you get this sacred shape. They called it the vesica piscis because it looks a bit like the body of a fish, but it is also thought to have been considered sacred because of its resemblance to female genetalia. If you do the maths, you can calculate that the ratio of its width to its length is 1 to root three, or 1 to 265/153 if you're an ancient Greek.
Now here's the really interesting part. There is a story in the Bible about Jesus meeting the apostles after his resurrection. The apostles are busy fishing and do not recognise Jesus, but he asks them how many fish they have caught. They reply that they have been fishing all day but have caught nothing. Jesus tells them to cast their net once more and they pull it back into the boat to find it filled with a great number of fish. The wierd part is, the Bible tells us that they count the fish and there are exactly 153 of them.
Many people have commented that this cannot be a coincidence and that the story must be a referrence to the sacred number of the vesica piscis, something that an educated Greek audience would have recognised as being part of Pythagorean philosophy.
