The Golden Ratio

raceBannon writes "The book surprised and fascinated me. I thought it was going to be solely about the Golden Ratio. Mario Livio does cover the topic but along the way he throws in some mathematical history and even touches on the idea that math may not be a universal concept spread across the galaxy." Read on for the rest of raceBannon's review. The Golden Ratio author Mario Livio pages 320 publisher Broadway rating 7/10 reviewer raceBannon ISBN 0767908155 summary Through telling the tale of the Golden Ratio, Livio explains how this simple ratio pops up in all kinds of physical phenomenon and debunks the idea that the ratio is present in many famous man-made structures and art work. Along the way, he provides historical tidbits regarding some of the well-known and not so well-known mathematicians throughout the ages and he tells the story of some of the more famous and not so famous mathematical advances. Finally, he discusses the possibility that mathematics may represent some kind of global truth that exists throughout the cosmos.

I have to admit that it is a little spooky to me that this ratio, this irrational number (1.6180339887...), pops up in many varied natural phenomena from how sunflowers grow to the formation of spiral galaxies; not to mention that the Golden Ratio and the Fibonacci Series are related. It makes you want to think that there is a God with a plan.

The Golden Ratio is defined as follows: In a line segment ABC, if the ratio of the length AB to BC is the same as the ratio of AC to AB, then the line has been cut in extreme and mean ratio, or in a Golden Ratio called Phi.

On the flip side, Livio squarely debunks the idea that the Golden Ratio is present in many famous paintings and architecture that has been postulated in previous books. He rightly points out that you can find the Golden Ratio in anything depending on where you decide to place the measuring tape. The idea that the Golden Ratio is such a symbol of universal beauty that it appears by accident in our great man-made buildings and artwork does not carry any weight. I think Livio makes his point.

He also uses the Golden Ratio as a framework to illuminate other historical tidbits about key mathematical figures, guys like Pythagoras and Euclid, who continue to affect the mathematical world to this day. I love this kind of stuff; the historical context of how and why these legends did what they did is very interesting to me. For example, I did not know that Euclid himself did not discover geometry or even make any great new contributions to the field in terms of ways to apply it. What he is famous for is organizing the information into a coherent fashion. He was a teacher of the highest order; so much so that Abraham Lincoln himself used Euclid's texts, unchanged after all those years, to learn the subject back in Lincoln's log cabin days.

The book is not all a philosophical discussion. Livio does use some simple math examples to make his points but it was at a level that I could follow. According to my college professor, I escaped College Calculus by sheer luck. Livio does provide the rigorous math examples in appendices at the end of the book (I did not bother with these).

Finally, Livio takes a shot at the idea that mathematics is a universal concept across the entire universe. To be honest, I have always assumed that it was. After all, I am a Trekkie and this concept goes unstated throughout all four TV series. The idea that mathematics is a human construction and probably holds no water in another civilization that grew up on the other side of the universe makes a lot of sense to me. I have to admit; I need to ponder that one for a while.

I recommend this book. If you like the history of science, your high school algebra class is just a little more than a dark fog in your memory, and you get a charge out of scientific mysteries, you will not be disappointed.

That is a very good and useful model, but it is entirely conceivable that some extra-terrestrial civilization has (or some future human civilization will have) a model that is just as useful but doesn't contain anything like electrons.

      You bring out a very subtle fallacy, and one that is tied to philosophical issues regarding mathematics. I bit of history is in order:

      The fundamental question is this: is, or isn't, mathematics an extension of logic? A smart man named Frege (read about him here) said, yes, it is. He showed a way to connect formal logic with set theory, which is the basis for mathematics as we know it.

      There was only one problem: Russell's Paradox. Bertrand Russell showed that, using Frege's axioms that defined set theory, we have a contradiction - Russell's Paradox. And as any student of logic knows, a contradiction can be used to prove anything at all, which means that mathematics as Frege defined it was not viable.

      To make a very long and very interesting story short, Russell (with Alfred Whitehead) attempted to create a foundation for mathematics that would not give rise to Russell's paradox - the Principia Mathematica. And everyone thought the world was cool.

      Then, in the 1930s, Kurt Godel came along and smashed a hole in Russell's approach by showing that, given a sufficiently powerful formal system, one will always find unprovable truths and irrefutible falsehoods. So mathematics was, by that line of reasoning, incomplete.

      This leaves the door open to a variety of critiques, the most relevant of which is that it is automatically not universal. After all, how could it be - there are things missing! We can't prove everything that is true, and we can't disprove everything that is false!

      Godel's argument tells us that we are unable to describe the universal laws of nature using non-universal and incomplete mathematics. That dosen't make mathematics useless - it just places a limit on what we can or cannot do. For instance, we cannot use deductive mathematics to describe the laws of nature in their entirety, because we know that any effort to be complete is doomed to failure - by Godel's theorems.

      Also, there are some specific areas of mathematics that lead to direct examples of non-universal, but nonetheless consistent interpertations of nature. Take, for instance, Euclidean and differential geometry. Euclidean geometry is the geometry of flat planes, whereas differential geometry describes abstract mathematical notions. It was once thought that Euclidean geometry is "sufficient", and that it is the simplest way of representing spacial relationships. However, as it turns out, differential geometry is actually much more simpler when it comes to dealing with, say, the theory of relativity - even though it is not intuitively connected to our perception of the universe.

      So in short, we have two different "geometries", each of which can, supposedly, explain spacial representation. Both are valid, but one is much more useful. Neither is universal. And yet, there is no contradiction.

For example, the number 1 as opposed to a capital S to complete addition (which is a logical law) means that 1+1=2 is the same as S+S=* because the system is beyond the physical characters used to represent the logic. The logic would not be different in an alien society. The laws of the universe do not change, therefore the same logic would be implemented. Using a 1 or an S would make no difference.

      There is sooooo much more, but just reading this story and people's posts makes me sad on a certain level. One of the oldest "truths" in the world...The person who is always least understood is not an artist, it is a mathematician.

      One thing that is provable in one system might not be provable in the other, or could even be wrong.

      For example, if we take the mathematical subset of Logic we have Classical Logic(CL) and Intuitionist Logic(IT).

      In CL, NOT(NOT(P)) |= P.
      It is easy to see why.
      Same with A OR NOT(A).

      However, for IL, something is only True if and only if it's provable.

      So, NOT(NOT(P)) |= P becomes:
      If there is no proof that a proof of P is impossible, then P is provable. This is invalid. The absence of a counter-example doesn't prove the fact.

      So we see that NOT(NOT(P)) doesn't imply that there is a proof of P.

      Same for A or NOT(A), because we cannot assume that it's always possible to either prove A or it's negation.

      One of the fundamental differences in the 2 math systems is that, in IM, it requires a constructive proof.

      So, in IM, you cannot prove something like that:

      Proof
      (...)
      Case1: A = X then (...)
      Case2: A != X then (...)
      (...)

      This doesn't work, for the same reason as A or NOT A, you need to prove one or another, so you need to prove that A = X or that A != X.

      Ok, the point is, these are 2 working, acceptable and valid mathematical systems, but they cannot be swapped, because CM != IM.

I don't remember the title, if you've read her work you may recognise it though: it was set in the Ekumen universe, sometime after the Age of the Enemy but before the story of "Left Hand of Darkness" and about guy from the colony of delta or gamma Draconis who ends up in the wilds of ruined Earth ... he was a mathematician and the story revolves around a race of people called the Shing who supposedly came to Earth and destroyed the interplanetary civilisation because they could lie in mindspeach (telepathy). Anyway, at the end of the story the character steals a Shing starship and examines the mathematics it uses and realises that the Shing are real and not a convenient invention because the mathematics is alien. Which got me thinking, would an alien civilisation produce an alien mathematics ? And how 'alien' could it be?

Or they could construct a loose set of intuitionist proofs a la the Greeks and mid 19th century Europe. Or some other combination.

Calculus would still exist: there were several attempts at a solution to the area under a curve over time that came so close that it makes you realise that the problem would have a similar solution though it would look different.

These reproducible "facts" are of course of extreme use to our society, and I don't think postmodernists would claim that science is anything less than a boon to our society and our understanding of our universe.

It was often said during Foucault's life that his own works of history were not really postmodernist, because in order to make a strong historical argument he had to betray many of the tenets of the postmodernist "we can't really know anything" dilemma.

      Wow, the shear ignorance in this entire article and book write-up is amazing. Not to truly upset anyone, but everyone here on Slashdot also appears to have a high school alegbra or entry level college mathematics background.

      Personally, I was rather surprised at the book review myself. I have found, however, many fine folk here on slashdot who appear to have a solid theoretical background in mathematics, perhaps they are hiding out on this one.

      To start with, Mathematics is not just as human as poetry. Where do you get that idea? Yes, pure mathematics (which is my passion in life) is essentially pure thought. BUT, nothing in mathematics is just 'made up'. All mathematics is based on fundamental, logical axioms (truths), and if anything were to violate those axioms, or the completely logical conclusions drawn therefrom, it would not be mathematics.

      I find this is an odd thing for a self-styled mathematician to say. First, I would not label axioms as "truths" but rather as "putative truths". That is their purpose (to be putative). They are styled from not only as "seeming to be true" or appealing to intuition, but also in their ability to form a basis of thought, their simplicity, a small number is required for important results (as in defining a system), and their seeming irreducibility. Axioms are usually formed "post hoc", with an idea of the desired results in mind. Don't you find it disconcerting that in Topology the definition for an open set in a metric is a union of open balls, but an open set in a topologcial system is definied simply as that which exists in the topology? It's a function of how strong of results you have, and later developments are "force fit" into prior studies. Much like topological systems are "force fit" into Metric systems by how they are to be constructed, thus claiming itself an abstraction of the latter.

      Furthermore, you claim that any results that contradict the "fundamental" axioms, is not properly called mathematics? You are aware of the results of Godel and his Incompleteness Theorem? It's more than the latest rave, it has results that bear directly on what you are oh-so-devoutly avering. In this light, what is mathematics, when it is either incomplete or contradictory? And quite often it is contradictory? Which set of axioms is the more fundamental one you wish to choose? And how do you choose it? These are problematic questions, with unforthcoming answers. Modern mathematics is rattled as it has been faced with it's own, ultimate, incompetence. It describes nothing but itself.

      You can think of mathematics as a grand puzzle, with each discovered piece and each mathematical truth found spelling out a larger picture. You can create bogus logic, bogus mathematical problems but it does not make it true mathematics.

      Disregarding your mixed metaphor "spelling out a larger picture", this doesn't make much sense to me. I guess I don't understand how you are differentiating bogus mathematics and true mathematics.

      E.g., the Constructivists accept only those proofs of the Classicists which do not use the Principal of the Excluded Middle (in the unsafe infinite cases). (This is a slight over simplification.) PoEM is a rule of inference, not an axiom per se; and it is a matter of philosophical contention.

      As another poster has mentioned, there are some postulated like the Axiom of Choice which are independent of the main axioms which seem to be required to prove some things, but we can otherwise live without.

A Mathematician will likely have a strong preference for using or not using AoC or PoEM, but as with the Parallel Postulates, can verify (or debunk) a proof as being correct with (or without) the assumption of the additional postulate -- as could an alien mathematician.

I won't even mention the Formalists, or labelling the computational exploratory dynamicists and their opponents, or try to differentiate the Intuitionists from the Constructivists (since I'm not sure which I am, or wish I was).

      In Geometry, there are several different geometries with the several different Parallel postulates (which map to different physical models: flat, hyperbolic, and spherical), the infinity (normal) or discreteness of points (which has more computer-like models!); some proofs work in all or most of these geometries, some work in only one; some theorems require different proofs in them. With AC and PoEM, however, you have layers of proven theorems; more things are demonstrably true the more axioms you have, but since alternate axioms are not on offer, there aren't alternate theorems. (Sometimes alternate proofs are possible, shorter with the high-power axioms, longer without; of course, with one too many axioms, even FALSE is provable, so you must avoid that ... but it is proven that there are unprovable truths if FALSE is unprovable, alas.) The Constructivists have reconstructed almost all (the useful bits anyway) of Classical Analysis ("Calculus made Difficult"), thus demonstrating that the Science and Engineering built on Calculus is not falsified by Constructivist logic questioning the (in their minds) dubious assumptions of the original proofs.

      Constructivists and Classicists recognize that each other are doing Mathematics, getting the mostly same results, but by different rules, different means -- and cherishing where there are demonstrable differences in what can be proven. Geometers may specialize in Hyperbolic or Spherical or Discrete, only because looking nearer the lamppost is better hunting ... not because the others are "false" in their eyes.

      So yes, 'blue' is an advanced concept that would have to be nailed down after months or years of discussion with the BEMs, possibly involving retinex algorithms to 'decide' if a thing is blue or not. There is, however, a 'blue' out there in reality to point at, and however they percieve it, we can explain to them that 'that' is 'blue'. Perception is relative, but reality is objective, for an agreed frame of reference.

      The arguement made by the original poster regarding blue is an argument that has been around for some time, and is not one that is directly related to postmodernism. Further, while it is my personal believe that postmodernism is in fact based on pure stupidity, that is tangential, as the question of blue is a legitimate and viable philosophical question.

      Your answer to that question is a nearly canonical definition of physicalism -- This is the belief that everything there is to know about the world is contained in the physical description of the world.

      This specific claim is answered by Nagel in his paper titled, "What is it like to be a bat?" and by Jackson in his paper, "What Mary Didn't Know."

      Nagel argues that if you knew everything there was to know about neurology and biochemistry and every other part of how a bat works, you would still not know what it was like to be a bat. This lack of knowledge is not explained in physicalism.

      Jackson tells the thought experiment of a girl named Mary who is born in a black and white room, is educated through black and white books and TV and film, and learns everything there is to know about physics, optics, the structure and workings of the eye, the optic nerve, the brain, etc. (Including of course that 'blue' has a wavelength of 475nm.) She is then let out of this room, and sees a blue light, and a wavelength meter that indicates the light is 475nm. Does she recognize the color blue as such, before she reads the indication on the meter? Does she respond by saying, "This is just as I have been taught, this is blue?" Then, knowing from her color-blind education that a sunset is considered by most people to be an intrinsically beautiful thing, she sees a sunset for the first time, the whole sky aglow in red and orange. Does she learn anything when she sees this? Does it surprise her? Specifically, before she leaves the room, she has an idea of what people experience when tey see a sunset. Do these ideas change after she has seen it? The key thing that mary learns in this experiment is non-physical information, called qualia. Defined loosely, qualia is the "What it's like" knowledge you have. And if you tell a colorblind person that blue is 475nm and red is 650nm, you haven't given them a shred of this qualia. They have no way to relate to your ideas, and have gained nothing from your descriptions but a few numbers to toss about in their heads. Their perceptions of the world will be fundamentally different. Their understanding of beauty will be based on things like proportion, or form, or contrast. What would a field of tulips look like to a colorblind person?

      To quote: If you are colorblind, it doesn't change the fact that the sky is, indeed, blue.

      No. If you are colorblind, it doesn't change the fact that the sky is, indeed, illuminated with a light with a wavelength of 475nm. That is a wholly different thing from "Blue."

      This is basically a postmodern viewpoint, that reality is socially constructed.
      A very naive--and misleading--way of putting it.

      A more accurate way would be to say that we cannot know anything in an objective (that is, absolute and unambiguous) sense: everything we learn comes through our senses, and so what we know is limited by what our senses can tell us and how we interpret the information our senses give us. What our senses tell us is in turn limited by our position (think relativity) and the limitations of our senses (we cannot perceive nearly so many colors as certain species of new world monkeys, for example). In fact, it has been demonstrated that just by the simple act of observing or measuring something we actually change the characteristics of that something (the unertainty principle).

      What these limitations mean is that what each of us percieves as reality is not only inaccurate with respect to 'objective' reality, but also differs from what other human beings perceive.

      More, those perceptions are meaningless until we interpret them. A particular frequency of electormagnetic radiation isn't 'blue light' unless the person perceiving that radiation interprets it as such. How we interpret our perceptions is socially determined. To use the light example, one could think of it as blue light, blaue Licht, lumiere bleu or perhaps even as shades of green light in some rainforest cultures.

      At its most basic, postmodernism is the recognition that what we understand as reality is actually a construct of our minds based on our interpretations of what we perceive, and that those interpretations are in turn based both upon what we learn from others (e.g., from a college professor or an author). That learning, and the process of acquiring it, are both social processes. Ergo, our 'reality' is, in a real sense, a social construct.

      Certainly, they recognize each other as "doing" mathematics. Just as we might recognize another species or such as "doing" mathematics even if it does appear radically different from ours. I appologize if you found my use of the word "politics" inflammatory, perhaps I was simply using it in looser manner than you might expect, I also don't wish to single out mathematics in this charge--I believe much of what we hold as acceptable means for establishing "truth" is indeed "politically" motivated. Or to put it another way, is ultimately determined through appeals to power. Certainly we cannot appeal to reason in establishing what reason is, as it is not yet properly established (or would you say we can as this argument itself is based on reason--eh? You see the difficulty? How do we escape what we've already assumed?). Now, you would be right to say that I'm using an exlcuded middle within this argument (in a rather fallacious way).

That said, I do not believe that thinking this way about mathematics diminishes mathematics in any way, nor is it my intention to use this push some other agenda.

Take insects for example, with some insects as they progress through the different stages of their lives they can greatly alter the type of food required to sustain them. Apples might be poisonous to them at one stage of their life, and at another stage they might be the only thing they can possibly eat. This could cause a race to evolve into a state where objects are not defined by quantity, but by their effect upon the race in question. They would simply convey to each other the state they wished to achieve, and then negotiate based on that.

An extremely socially structured species might have a much more complex system of resource delegation. With apes, for example, you are fed based on your status within the group, with the silverback getting first choice, and then all the others getting their pick from the leftovers based on their status with the silverback. If everything was delegated in such a way trade would simple come down to contests of social dominance, with the losers simply being left with the scraps. Very little need to quantify.

Even things like counting from one to ten is a model for concrete objects, and provides a way of, say, making sure the number of cows you have today is the same as the number of cows you had yesterday. At the higher level, mathematics lets you model shapes, motion, acceleration, and gravitational collapse of entire stars.

Hundreds of other branches of mathematics exist to model different things in different ways, and none of them are "right" -- they all are optimized for particular problem-solving.

    The golden mean (proportio divina or sectio aurea), also called golden ratio, golden section, golden number or divine proportion, usually denoted by the Greek letter phi, is the number phi = (1 + sqrt 5)/2 = approx. 1.618033 ... the unique positive real number with phi^2 = phi + 1 and the equally interesting property phi-1 = 1/phi.

    Two quantities are said to be in the Golden ratio, if "the whole is to the larger as the larger is to the smaller", i.e. if (a+b)/a = a/b. Equivalently, they are in the golden ratio if the ratio of the larger one to the smaller one equals the ratio of the smaller one to their difference: a/b = b/(a-b).

    After simple algebraic manipulations (multiply the first equation with a/b or the second equation with (a-b)/b), both of these equations are seen to be equivalent to (a/b)^2 = a/b + 1 and hence a/b = phi.

    The fact that a length is divided into two parts of lengths a and b which stand in the golden ratio is also (in older texts) expressed as "the length is cut in extreme and mean ratio".

    The ancient Egyptians and ancient Greeks already knew the number and, because they regarded it as an aesthetically pleasing ratio, often used it when building monuments (e.g., the Parthenon). The pentagram so popular among the Pythagoreans also contains the golden mean. It is also sometimes used in modern man-made constructions, such as stairs and buildings, woodwork, and in paper sizes, however it is a myth that the European formats (such as A4, which is actually cut to 4 decimal places of sqrt 2) are cut in the golden mean. Recent studies showed that the Golden ratio plays a role in human perception of beauty, as in body shapes and faces.

    A possible reason for its supposed attractiveness is shown by the Golden rectangle, which is a rectangle whose sides a and b stand in the Golden ratio. If from this rectangle we remove a square with sides of length b, then the remaining rectangle is again a Golden rectangle, since its side ratio is b/(a-b) = a/b = phi. By iterating this construction, one can produce a sequence of progressively smaller Golden rectangles; by drawing a quarter circle into each of the discarded squares, one obtains a figure which closely resembles the logarithmic spiral theta = (pi/2 log(phi)) * log r.

    Since phi is defined to be the root of a polynomial equation, it is an algebraic number. It can be shown that phi is an irrational number. Because of 1+1/phi = phi, the continued fraction representation of phi is 1+1/(1+1/(1+...)) = [1; 1, 1, 1, ...]

    The number phi turns up frequently in geometry, in particular in figures involving pentagonal symmetry. For instance the ratio of a regular pentagon's side and diagonal is equal to phi, and the vertices of a regular icosahedron are located on three orthogonal golden rectangles.

    The ratios of justly tuned octave, fifth, and major and minor sixths are ratios of consecutive numbers of the fibonnaci sequence making them the closet low integer ratios to the golden mean. James Tenney reconceived his piece For Ann (rising), which consists of up to twelve computer generated upwardly glissandoing tones, as having each tone start so it is the golden ratio (in between an equal tempered minor and major sixth) below the previous tone, so that the combination tones produced by all consecutive tones are a lower or higher pitch already, or soon to be, produced.

    The explicit expression for the Fibonacci sequence involves the golden mean. Also, the limit of ratios of successive terms of the Fibonacci sequence equals the golden mean. From a mathematical point of view, the golden ratio is notable for having the simplest continued fraction expansion, and of thereby being the "most irrational number" worst case of Lagrange's approximation theorem. It is also the fundamental unit of the algebraic number field Q(sqrt 5) and is a Pisot-Vijayaraghavan number.

    I can certainly see most people's point of view that math is some universal, even metaphysical, system. In some ways it certainly is. However, one only needs to study a bit of math history to see how much this viewpoint has changed from the time of Newton through Godel to the present. A very convincing book by Morris Klein called "Mathematics: The Loss of Certainty" is a really great read on these subjects. Klein is a great mathematical historian, and this book tracks the progress of both the theoretical and philosophical viewpoints of math throughout history. I think when people say that 'math is not universal', it means mostly what Klein's conclusion is. There is no 'right' system of mathematics.

    Take geometry for instance, it 'seems' right and it works in lots of situations. But change one or two of your axioms, and you've got a completely different geometry, which is equally valid in theory and application. Math like anything, is about choosing the right tool for the job. Now geometry is one thing because we have a physical conception of it mostly, but as for other things, take number theory, I don't know. Are there different number theorys based on choosing different sets of axioms? Probably. So which one is the right one? Whichever one works for what you need it for. The fact that math is somehow 'out there' is a very Platonic concept. That's not to say it's wrong, before I read Klein's book, I was definitely a supporter of that viewpoint. But after that book, it seems a little shortsighted, and to tell you the truth, it takes a little of the mystery behind math away, which is too bad really.

Basically, cultures have tended to spawn organizing systems, which are in essence mathematical. The lack of such a system would suggest the lack of ability of abstraction of patterns, etc., which would suggest a creature without the means for formal reasoning. If we seek a dialogue between us and the inhabitants of another world, they will certainly have to decypher or reason out our messages (e.g. the golden record aboard the voyager 1), which would then suggest an ability to reason, and understand mathematical ideas.

      Yes, and no.

      It is important to understand that we invented math. It wasn't just out there, on its own, waiting to be discovered.

      We defined the number 1, and what it means. We defined the number 0, and what that means. We defined addition and multiplication, and the results of performing those operations on various numbers.

      Now, you take a computer. Interesting enough, its "math" is not based on addition and subtraction. It's based on AND, OR, NOT, and so forth -- the basic bit-twiddling operations. And it's still able to do "our" math, despite the fact that "its" math is completely and utterly different. That's interesting, but not important, because the two mathematical systems are easily interchangeable.

      However, it's easy to envision systems which are *not* easily interchangeable. Take imaginary numbers. Why is sqrt(-1) == i? Because we said "Let there be a number i such that i * i = -1". That's it. i is the square root of negative one because we said it is, and for no other reason. We could just as easily have said "there is no number i such that i * i = -1", and it would be just as valid of a way of looking at things. Sure, it would completely change the way we do higher math, but it would not be wrong. We made these constructs, and defined their behaviors, and they work the way we say they do.

      What if an alien race had introduced a number q, such that q = [result of some other impossible operation], and then based half of their mathematics around it? That's exactly what we did with imaginary numbers. If we have i and they have q, and these two concepts have nothing to do with each other and aren't easily convertible, you've got two entirely different, but both perfectly valid, mathematical systems.

      It's likely that all intelligent species will have pretty compatible basic arithmetic, but as soon as you get to higher-order math, all bets are off, because we will have defined the axioms differently.

    Then, for more complicated mathematics, you start having lots and lots of Axioms. An Axiom isn't TRUE or FALSE, it's just an Axiom. If you agree with the Axiom, then that's great. However, no universal concepts precludes you from not agreeing to an Axiom, and if you do you change a LOT of things, but it doesn't mean it's wrong.

    For example, X ** 0 = 1. Or a division by 0 is impossible. Why? No reason, those are axioms, so you have to agree that it's that if you want to do lots of classical mathematics. You can 'Argue' axioms, but it's just that, arguying, you cannot prove without a single doubt an Axiom(beause then it's not an Axiom =)

    Another example, in logic this time, is P = NOT(NOT(P)) and NOT(NOT(P)) = P. However, you could disagree with the second one and agree with the first and then(in additions to new and/or modified Axioms) you'd end up with a NEW logical system, vastly different from the classical logic: it's called Intuitionist Logic and isn't less valid than Classical Logic, just different.

    One thing proven in one of the system might not be provable, or even could be false, in the other system.

    This just is a small glimpse of why Math is certainly not universal. Simple counting(add/sub) MIGHT be universal, but I do believe it stops there if it does start there(you'd have to enter philosophical debates over this).

The scientist (and, indeed, the philosophy of science) requires that the rules are cast by something external to humanity, that is, the rules are unalterable and are the same for each person. This is the basis of repeatable experimentation, and has proven itself far more successful than the alternative explanation.

You can look into the past and see where the "softer" sciences, especially psychology and medicine, have made errors based on prevailing social beliefs. But more fundamentally, I believe there are limits to scientific thought. For instance, perception is an important place to attack science, since science hasn't had much success in probing perception. This is probably because science deals in concrete concepts that can be described cleanly with language (e.g., the universe is expanding, the Earth goes around the sun every 365 1/4 days, every cell contains protein, etc.), but we can't describe perceptions in any way that is simple or concrete.

    I studied the history of mathematics back in college, and one interesting culture we discussed were the Mesopotamians. While base-10 systems were typically used amongst ancient civilizations, these guys went out and used a base-60 system. So, if you wanted to count to 61, for instance, you would count all the way from 1 to 59, then place a "1" in the 60s place holder, and add another "1" in the 1s place holder.

    I realize for most of us this concept is old hat, since we know binary, or hex, or octal. However, this relates to the discussion of alien mathematics because here we have a system of non-traditional mathematics that was actually used and had its own structure. Many people argue that aliens may not understand concepts such as "prime numbers" or such. But even the Mesopotamians understood these concepts and had their own problems that we face in a base-10 number system.

    For example, the Mesopotamians loved the number 60. After all, it is evenly divisible by 1, 2, 3, 4, 5, and 6, right off of the bat. But the number 7 always gave them headaches. Why? It's the first number where its reciprocal does not terminate (i.e. 1/4 = .25) or have a predictable pattern (i.e. 1/3 = .33333...). Just because the enumeration or base of a number system may be different, the rules of mathematics are still the same. And, as other Slashdot readers state, the very laws of nature and movements in the heavens will accurately adhere to different number systems.

    Now, aliens may have a different way of looking at mathematics, or may have come up with different structures for representing mathematical ideas. Think of the Indian man who found a book on algebra and without any sort of education or outside intervention devised many proofs, some of which were old, some of which were new (I think his name was Ranmujon). Alien mathematics may not include things know, and vice versa. But I must agree with the general thought--Mathematics is universal.

All of those classes have stuff that students are required to know, and there's not enough time in the day, or energy in a teacher to a) teach the required stuff, b) teach the important stuff, and c) deal with a classroom with 30+ kids with understanding levels that span the bell curve. The required stuff is universally accepted as required, or the kids don't get into college X, and that's why the ideals go out the window.

    The ratio of sequential numbers in any Fibonacci-generated sequence converges to phi.

It turns out that the successive iterations of the fraction (in simplest terms) follow the following pattern: the next numerator is the old denominator. The next denominator is the sum of the old numerator and the old denominator. If we ignore the division for a second, we're generating a sequence of numbers where each number is defined as the sum of the previous two. So, essentially we're generating a Fibonacci sequence out of the numbers (1/x + 1) and (1/x + 2), but with the ratio (division) baked in.

      Aliens would not necessarily even communicate with anything but their environment. But their methods of communication would probably differ into inscrutability. If their spatial metaphor were, for example, "noneuclidean", perhaps fractally self-reflexive in semi-imaginary space, or mapped onto a moebius bottle, etc, would 19th Century Europeans, even French ;), be able to communicate mathematically with them? Scale that outwards, as there's little chance that unnsynchronized mental evolution across the Universe will coordinate even as closely as that example. Even "subtraction" has an Earth human bias of conservation in our maps of physical reality. On the Internet, for example, when I give you a file, I still have it; subtraction isn't fundamental. Likewise, there are other nonzero-sum scenarios which could dominate the organization of an alien consciousness. Only humans would see it as "nonzero-sum"; aliens would see it as the basic reality, like a fish doesn't notice the water it's in.

      But again, I still hope there's enough diversity in alien intelligences that we will find at least one with which we share some consensus reality, and with which we will safely communicate.

    Cursive's a hair different---reading cursive is HARDER than reading printed letters.

    Cursive is about speed - you don't have to ever lift your pen/pencil/quill.

    If you were to sit beneath a palm tree on a beach and write the great american novel with a pen and pad, you'd do it in cursive. Print would cramp your style.

    The point of courtesy here is that it's for _you_ to read. If you need to write for others, always print. For substantially alphanumeric writing, always use smallcaps, to avoid numeral/letter confusion.

  187. Vedic Math and Indian Math. by The+Cydonian · · Score: 2, Interesting

    I read the book in question a couple of years back. Just would like to say this:- you'd like to distinguish between arithmetic and mathematics, as also, perhaps, between actual scientific history and propaganda.

    Vedic 'math' is mostly arithmetic; it's about how to multiply numbers faster (cool method that; helped me throughout most of school) and, like you said, long form division. Even in that, I doubt it was from the Vedas themselves; I remember reading about those 'tricks' (using the term in a broad sense; not a negative connotation) even before I read Tirthaji's book in an old book published in 1936. The book claimed it was a translation of an even earlier Sanskrit book on mathematics (an absolutely fascinating treatise called Leelavati Ganitham); don't quite think it mentioned any Vedic references.

    Indian mathematics, OTOH, was mostly from the Medieval Ages, between 5th and 10th centuries CE, when mathematicians such as Bhaskaracharya and, of course, Aryabhatta, wrote their treatises. The reason, apparently, was astronomy and trade; when you are the center of a globalised trade in gems and spices, you want to get your math right.

    Quite possible that ancient India knew about calculus, but it's more likely than not that it was a result of a gradual excellence in the sciences, not something that's been left to us automagically by our Vedic ancestors.

    The flaw in that line of thinking, which many on /. are making, is assuming that what we percieve singularly is similarly percieved by another species....

    Now another lifeform comes along, one which can percieve the entirety of the book in time/space. They percieve not only a different book than we are capable of, but further, they may percieve each temporal book as a seperate item, just as we percieve spacially translated objects as seperate. So where we see a single book, they see an infinite number of books. We can only assume that their method of counting would differ from ours, or that we would be unable to correlate ours to theirs because we can not percieve the many, only the one.


    So close to right that I can't resist replying... The problem is that if lifeform X perceives the book as some kind of collection over time (or something), it still has a concept of `the book'. Even if X can't differentiate between `the book now' and `the book always' (or something), it can still count by noting the existence of `the book' and `the other book' or `the book now' and `the book a little while ago'. It doesn't matter if X and you or me think that `the book' is the same thing; we're still enumerating.

    In fact, as long as lifeform X can determine that [something] exists and [something else] exists (or even may exist), maths sneaks back in. If X cannot distinguish objects, the question of how it can interact with the world becomes much more interesting.

    And this leads to a problem that's been bugging me for years: What is an object anyway? What I think of as `my desk' is just a local irregularity in the chemical soup on the surface of what I like to think of as a `planet' which is just...

    Mathematics and Logic are just models, founded on postulates assumed to be true. An entirely different civilaztion may have developed their own math and logic using entirely different axioms, or they may model their universe in a completely different manner.

    Since *our* mathematics relies on the set theory, we should realize that we can never truly define the universe (universal set) with mathematics (a subset). The best we can do is increase the scope of the mathematics in a way that it accurately models a good portion of the universe for enough applications.

  192. Social Construct?! Mathematics is too universal by n1vux · · Score: 1

    This is the social construct that is mathematics.

    Thank you, that is a more felicitous phrasing than "politics", especially in a debate where the audience are largely likely to use the engineering mis-definition thereof. This is indeed where we disagree. The Formalist claim that mathematics was doable strictly formally without recourse to social process was disproved, within mathematics, around these questions of Axioms and Proof, before "Social Contract" theory was the rage; you are effectively correct, in that it was demonstrated that there was a matter of taste in deciding what was formal enough. Thus, Peer Review is always required; machine verification of proof will always require at least peer review of the machine, and likely a Peer Review that what the Machine reviewed matched the theorem claimed.

    I gather you are fond of post-modern social-relativist deconstruction of everything to morally equivalent social constructs. This may be invogue in the liberal arts. It is not a mere coincidence that when Trudeau/Doonesbury poked fun at this sort of thing it was a Math professor who was charged with cultural insensitivity because a student claimed 2+2 wasn't 4 in his culture.

    There is a social contract in doing mathematics, but it does not follow that all of mathematics is a social construct ; Mathematics is discovered, not created. Our matters of taste (over how it is done, our "rules") will affect the texture of the mathematics found, how it's organized, and what is found early or at all; it affects what of True Platonic Mathematics we know or accept to be true.

    If Mathematics were as you claim a "Social Construct", there could be more than one such, with mutually incompatible conclusions. This is not so. It is demonstrable that no consistent logic can prove all true statements -- that means no logic can prove all true statements and only true statements. Thus each Mathematics(as we know it) for different "rules" will have a different subset of all true theorems proved, grow asymptotically closer annually -- but none will have things that the others prove false. As described in my prior post, the varying philospophies of mathematics admit more or fewer theorems, based on what is available for proof by their evidence, but never do different philosophies get different answers -- only sometimes only some get no answer or assert no answer is possible. (Differing Geometries differ from differing philosophies of mathematics, since one must switch back and forth at will, they are not matters of taste, it is imperative to explore all 3+N geometries and catalog the differences.)

    That all Mathematics is intrinsically the same and discovered can be seen in a simpler experiment, at the level of Arithmetic -- the mathematics of the Babylonians and the Mayans and each other civiilzation which developed their own enumerations are commensurable, some of more power and expression, but all equivalent -- in each of the 5 or so different formal schools of "doing" mathematics.

    "truth" is indeed "politically" motivated. Or to put it another way, is ultimately determined through appeals to power.

    We definitely have parted company long since if you think this applies to Mathematics.

    There is be power in editing journals and chairing departments, a power particularly strong in some academic fields. When new theories must wait for the Chairs and Editorships to be relinquished by the heirs of the theory to be displaced before it can be published, one can speak of Truth by Power. This can be the case in fields that work by approximation, as in the hard sciences, and is very much the case in "soft science" fields where "theory" is fashion, not tested. I won't cast aspersions on certain so-called sciences with this sort of cycle by naming names, but we know who they are.

    Mathematics does not create new truth by tearing down old, but by building upon old, so Truth by Power
