[i][Mathematics that is}[;)][/i]
Since it's popular now to bring up "apparent" inconsistencies in certain fields of inquiry (Biblical theology for one), I'd thought I'd continue this with a few inconsistencies or contradictions in other fields.
I'll start with a just few easy ones... Mathematics and Euclidian Geometry:

#1)
Point: a zerodimensional figure.
Line Segment: the set of points consisting of two distinct points and all inbetween them.
A line segment has a defined dimension (i.e. exact length)
[u]Based on these definitions[/u], since a single "point" has zero dimensions, how can a set of zero dimension points have a defined dimension?
Does a line segment have width? By definition  no.
Then how do dimensionless points aligned sequentially in a segment create length but no width?
How can many line segments placed next to each other create a plane with defined width if each line segment creating it has no width individually?

#2)
According to the Pythagorean Theorem, the length of a hypotenuse (C) of a right triangle is equal to the square root of the sum of the other sides (A and B) each squared. (A^2 + B^2 = C^2)
If A and B are exactly equal to one, the length of the hypotenuse is an irrational number (square root of 2).
I can conceive that there exists a real, physically tangible triangle with two sides that measure exactly 1.000000... meters long, but the hypotenuse cannot be exactly measured.
How can the physical length of this hypotenuse be exact (i.e. it does have an exact beginning point and ending point), yet its measurement proves not to be exact (the measurement has no ending)?
In other words, since this hypotenuse is a line segment with definite beginning and ending points, how can its measurement have no ending?
(this one is not exactly the same as Zeno's paradox so don't use that solution)

#3) (my favorite)
There is no logical answer to the question, "What is the square root of negative one?"
So Einstein CREATED the imaginary number "i" to fill in the gap in his work in relativity.
Since the imaginary number "i" has no real (i.e. physical or logical) origin, it's a fudgefactor and without it, conventional mathematics or logic can not fill in the gaps in relativity.
Yet "i" is used to link space, time, matter, energy, gravity, and inertia, all to a single unit of conversion.
So why not just call "i" an "invisible spirit" and say that this "mysterious spirit" is the inexplicible, unexplainable, illogical force missing from our understanding of relativity?
Isn't "i" to mathematicians what "God" is to theologians  both are undetectable, untestable, illogical entities simply used to fill in the gaps to problems where no logical answer will suffice?

Okay, I do welcome insightful explanations to these "apparent" inconsistencies in the way many here delighted in thrashing out the inconsistencies of the Bible.
Once these "apparent" mathematical inconsistencies have been thoroughly hashed out, I'll bring up the apparent inconsistencies and contradictions in Chemistry, Physics and Biology to toss around.


I am not the means to any end others may wish to accomplish. I am not a tool for their use. I do not surrender my treasures to be flung to the winds as alms for the poor.

Please list the rest of the inconsistencies. I am fascinated. No sarcasm.


That's PERSEC, not OPSEC. AvengeR15

What's wrong with the square root of 2 being irrational? If that tickles your bum too much you could always measure the sides in inches instead of meters that would probably help hehe. BTW I like where you are going though.



I just finished a semester of algebra on Thursday. You people are making my head hurt. [BD]

Imagine a man when it all began

Hey you're right! That's really messed up.
Seriously, you are gonna compare the sqaure root of a negative number being represented by "i" in certain "theories of relativity" to the absurdities in the bible?
Furthermore the formulas that use "i" are just that "theories." They are not fact but assumptions used to search for the truth. There are scientific knowns such as E=mc2 which are no longer just theory because we have proven them.
You see in math and science, when something is not known for sure it is assigned a hypothosis, theory or a variable unknown. This is science saying "Gee, we really don't know but lets see if we can find out." Science and to a lesser extent, math are based upon the fact that we don't know something. They are a search for the answer. Much of science is categorized as "current theory" this means our best guess based upon available data. Science freely and readily admits when it doesn't know and when it has been wrong. Because REAL science is simply the search for truth and understanding.
If you presented bible stories as theoretical history and theology, nobody would object. But it is presented as fact. And it never admits when it is wrong.



And now for something completely different:
111,111,111 times 111,111,111 =
12345678987654321 [:D]



I hated math in school and I hate it now....[rolleyes]



"less filling" or was that "tastes great"?

science if different from math in that science is based in part on physical measurements, while math is based only on logic.
scientific hypotheses, after being tested in the physical world, are either rejected or accepted as working theory. on the other hand, with mathematical theories, the only test is that of logical consistency.
regarding mathematics, you're not describing logical inconsistencies or contradictions. you're saying that it doesn't make sense to you. there's a difference.
#1)
infinitesimals are infinitely small numbers.
when you add an infinite number of infinitesimals together, you can arrive at a finite number.
particular to your question: a point has an infinitesimal length, and when you add together an infinite number of points, you can arrive at a finite lengthed linesegment.
#2)
there are different ways that numbers can be "exactly known". many numbers are exactly known, though they cannot be expressed as rational numbers.
the squareroot of 2 is exactly known. however, it cannot be expressed as m/n, where m and n are integers. so it is not a rational number, but it is still a number.
#3)
there is nothing "imaginary" about i. it was named inappropriately. it has as every bit as much physical and logical reality as 1.

A point has ZERO length. Zip, Zilch, Naught, Nothing, Nada  NOT "infinitesimal length" but "0.0000..." length.
0 + 0 = 0 (except with geometric points it seems)

If so, can someone explain why Euclidean geometry is the exception to the basic rules of addition using zero? View Quote Originally Posted By The_Macallan:

but you wish to discuss euclidean points, not newtonian points. you seem to think that euclid writes "0+0=1", but he does not write this. what is the inconsistency/contradiction you find in euclid's theory? where is the logical breakdown?

in logic and mathematics, a theory is assumed to be consistent unless a specific logical contradiction is found in the theory. you are pointing to a phenomenon that challenges your intuition (it challenges mine too), but you are not pointing to any contradiction.
to prove that euclid's theory is inconsistent, you have to write out a mathematical proof that ends with the statement "0+0=1". (in thousands of years, no one has succeeded in finding a logical inconsistency in euclid's theory.)
