Many people are attracted to the natural sciences, and even engineering disciplines, not because of a desire to improve the world, but because they find pleasure and abstract beauty in those fields. Yet undeniably work in those areas can lead to benefits for "society", and therefore people doing research in those areas are funded, even if their personal reasons for doing the work have nothing to do with those benefits. Likewise with mathematics, many ideas thought of as purely abstract and disconnected from practical application have turned out, later on, to be useful tools in understanding various real-world phenomena.

      It is totally unscientific and ultimately counter-productive to close off areas of inquiry because at the time they are undertaken no one can know exactly what the consequences will be. And ultimately the motivations of the people involved are irrelevant; we know based on history that there could turn out to be uses for it in the future, even if neither "we" (the society making the decision to support the research), nor those doing the research, can see any at this time, and this potentiality alone should justify providing support.

      It's a thing of beauty because it has produced fascinating finds with respect to the relationships between various prime numbers and relatively prime numbers (Euler's Totient function). Modular exponentiation is fascinating--how this works with primes (i.e. 3^1 mod 7 = 3; 3^2 mod 7 = 2; 3^3 mod 7 = 6; 3^4 mod 7 = 4; 3^5 mod 7 = 5; 3^6 mod 7 = 1; 3^7 mod 7 = 3 and it all REPEATs) -- so is fast exponentiation, exponential inverses, modular inverses, Fermat's little theory etc.

      Its a good point; even if you believe that mathematics needs to yield real world applications in order to be justified, it would be short cited to restrict research to topics with anticipated applications.

      However, I think research in mathematics should be encouraged for more idealogical reasons. We enrich our culture whenever we add to our knowledge of anything. This is why we support the study of fine arts, literature, history, anthropology etc. We do not demand applications from these subjects; the payback is less tangible than that.

The fact that pure mathematics provides a rich resevoir of knowledge that is heavily exploited by all fields of science and engineering should not be construed as its sole justification.

      If mathematicans aren't really interested in helping understand the world, why should society fund them?

      This is an important question, and in my opinion has two particularly valid answers.

      The first of these is the one that usually gets advanced - that (as with other pure scientific disciplines) we just don't know what `useless' knowledge might turn out to be useful or vital in fifty year's time. This is all well and good, and a perfectly decent reason to study something.

      The other one, which I've come to believe more strongly over the past few years, is that which is often advanced in support of arts funding - that it benefits a society greatly (often in intangible and undefinable ways) to study and research things whether or not they have any practical use.

      This is a point which, in the UK at least, a succession of education ministers have either missed or fundamentally disagreed with over the past few decades.

      Last month, Charles Clarke, the current Secretary of State for Education made some very disturbing comments about how he didn't see the point in spending taxpayers' money on maintaining a group of ``mediaeval seekers after truth''.

      He was initially misquoted as saying he didn't see the point in the study of mediaeval history, which rightly got a lot of historians angry, but a later statement clarified that he actually didn't see the point in studying any subject which didn't have a direct positive contribution to UK industrial or economic interests. Which I find even more disturbing - it's understandable (even ok) for the Chancellor of the Exchequer to have such a viewpoint, but I like to think that the Secretary for Education should at least see some worth in all of the education system.

      A friend of mine (an eminent evolutionary and reproductive biologist who's also helped design aliens for people like Anne McCaffrey, Larry Niven and Jerry Pournelle, and co-written a couple of books with Terry Pratchett) once said

      ``Most people think that the end-product of a PhD is a neatly-typeset hardback thesis. It's not - the end product of the PhD is the person who's done the PhD''

      which I rather agree with. Studying or researching any subject changes the way you look at the world - often for the better. It teaches you new or variant modes of thought which you can then apply (often unconsciously) to other areas of interest.

      For example: A former office-mate of mine now works for the NHS Breast Cancer Screening Service. The topic of her thesis (permutation group theory) is irrelevant to what she does now. But I find it tremendously reassuring to know that there are people that well-educated, and who have been trained to such a high level in thinking clearly and carefully, involved in something that important and worthwhile.

Maybe you're just not out of secondary school yet, but for your information, trig, calculus and the rest are useful for a lot more stuff than what you mention. All the different areas of maths often intermingle in any physical subject.

    For the interesting tidbit of information, there has yet to be a mathematical discovery which has not found practical applications. Even group theory, which at first was thought to have nothing to do with physics or any engineering sciences, was found to be very applicable to some extremely interesting problems of fundamental physics (describing the symmetries of fundamental particles).

    A mathematician, the Hungarian lover of numbers Paul Erdos once said, is a device for converting coffee into theorems.

    Erdos himself was a device for converting speed into theorems. Ironically he lived to be 83 years old, prolifically creating new math until the very end.

    Like all of Erdos's friends, Graham was concerned about his drug-taking. In 1979, Graham bet Erdos $500 that he couldn't stop taking amphetamines for a month. Erdos accepted the challenge, and went cold turkey for thirty days. After Graham paid up--and wrote the $500 off as a business expense--Erdos said, "You've showed me I'm not an addict. But I didn't get any work done. I'd get up in the morning and stare at a blank piece of paper. I'd have no ideas, just like an ordinary person. You've set mathematics back a month." He promptly resumed taking pills, and mathematics was the better for it. - Paul Hoffman, The Man Who Loved Only Numbers

      The question should be unambiguous, otherwise you are testing to see if people "think like you". If you call it an intelligence test then you must be the definition of intelligence. The question should have opened by stating that these symbols should not be interpretted as representing mathematical numbers.

      The Mensa/ Ockham's razor based approach is to find the solution which makes the fewest possible assumptions.

      I think you are misusing Ockham's razor. Ockham said entitites should not contain any uneccesary multiplications. Theorizing that one number is unique because it is prime and the others are not does not contain any unecessary assumptions as primality is a basic feature of certain numbers that is true of them regardless of the system used to express them.

      If you a) Write the number in binary it is not symmetric. Mind you, it is:) OK.

Try Adobe WoobBlock or something weird. So symmetry is NOT a property of the number itself. Primeness is though.



      Yes, but the whole issue here was whether the symbol should be just a character or treated as an abstraction for a numerical quantity. All these points assume that we have decided that it is an abstraction for a numerical quantity (and that the symmetric property should hold for other ways of writing the same numerical quantity).

      If the figure 8 is just a meaningless character, then you write it as 8, with the same font, in Maya as well.

      Well, I am probably extrapolating it beyond what he would ever have done; but I am not the first to realize it's applicability to this type of problem.

      So you are saying because numerical symbols are simpler to explain as shapes than as a field of philosophy, that any problem involving numbers should first consider their shape since any solution involving that would be simpler to explain?

      No, you haven't realized a valid use of Ockham's razor. You are simply using the validity given to it, and twisting its meaning to make your argument seem more valid.

      Ockham's razor, as it applies to philosophy, eliminates one of two theories trying to explain the same thing. For example, why do planets in the sky move in such a peculiar way? One theory says "the sun is at the center and we and the other 8 are going around it" the other theory spends a few pages of explanation about the earth being at the center and the planets going around it, and on another sub orbital on their major orbit... all kinds of craziness. Clearly one requires less multiplications than the other.

      If you want to apply Ockham's razor here, you must have two theories explaining the same thing. But they don't. One theory says "8", the other says "5".

      By your logic, 1 + 1 = X, because you can make an "X" by crossing the two shapes and it is much easier to explain two shapes overlapping than elementary arithmetic. Just because there is an easier explanation to get a different answer doesn't mean the easier explanation is right, or that Ockham's razor is in any way involved.

      This is a circular argument. The whole point with the other solution is that "8" can be analyzed by just the properties of the symbol itself, and not by the properties of the mathematical abstraction. You assume it is a mathematical abstraction, and then use that assumption to prove itself.

      Please quote me proving that it is a mathematical abstraction. I assume that they are numbers and not shapes and then using that assumption evaluate that one and only one is prime. But that doesn't prove that they are abstractions, merely that there is a valid answer if they are.
