    Equivalence classes for a graph

    Is there a way to figure out the number of equivalence classes for all graphs of order n, size k?

    Need suggestions for class project (poli. sci)

    How do you Fourier transform data? jhe threw out some really good ideas. I'd go with those kinds of things: comparing two sets of data and finding very simple, linear relationships. I'm almost positive that's exactly what the professor is looking for.

    What Factors Drive Genius and Creativity in Unknown Discoveries?

    I think you're mixing two different things up here. A genius is not necessarily an innovator. Geniuses merely have an innate supernormal cognitive ability. Innovators have the ideas. And you're right: ideas don't form out of vacuum and they certainly aren't innate.

    Does Randomness Exist? Evolution & Implicate Order

    "Randomness" is a term that only has meaning when you provide a context. It basically means a lack of information. For example, if we know the state of every molecule in the universe at every point in time since the Big Bang, well those genetic mutations would not be random. But we don't know...

    Why sell capital at a price higher than what it costs?

    The easy answer to francisco's question is because they can. Why would you not want to sell your product for more when you can? Also, just a silly rant but I really hate the concept of production as value-added. It's such a macroeconomic (blaaarrgh) idea that muddles complex economic, social...

    Binomial distribution - killing cells with x-rays

    That would be interesting. And you look at P(X1>=2, X2>=2, X3...)? A very simple and elegant model but I have a feeling it's been superceded. I would look at graphs, random fields, anything with that sort of mapped network type of thingie. Haven't really looked at that kind of stuff in a while...

    Semantic completeness (in linguistics)

    Yeah, that's the site. I presume interpretation means changing a sentence into a meaningful concept. But what makes a sentence interpretable? That it is syntatically and semantically complete, right? Seems like a tautology to me.

    Semantic completeness (in linguistics)

    Well I've been trying to look through a course in Psycholinguistics on MIT OCW and I got to a section about constituenthood, which requires a sequence of words to have syntactical and semantic completeness. I'm pretty sure it just means that the sequence makes sense, both in terms of meaning and...

    Semantic completeness (in linguistics)

    Yeah I think that's more the mathematical definition of semantic completeness. But thanks for the help.

    Semantic completeness (in linguistics)

    This is kind of a dumb question but I really can't find a definition anywhere. Can anyone help?

    Generating Function for Probability of Equal Sums in Multinomial Distributions?

    Actually now I understand. I'm just now sure exactly how to get to the generating function.
