Is there a name for a set of numbets that includes: 0 Numbers obtained by negating numbers of this set Numbers obtained by multiplying numbers of this set Numbers obtained by raising a prime to a number of this set I know for sure that this includes 1 (Prime to the power of 0), all prime numbers (Prime to the power of 1), all natural numbers (Because each of them has a prime factorization), all whole numbers (By negating positives), and all rational numbers (Using negative powers). Not all, but some irrational numbers are possible as well, even transendental. I want to know because I was pl ..read more

We know that certain kinds of sense can be rather described with clearly studied mathematical structures, say vision is just a 2D field of R^3; and there are also kinds of sense that haven't been managed to be embedded into a nice structure, say smelling. To be rigorous we're only talking about their input spaces, we're not looking at what's happening behind the sensors. We also know that there's a thing called synesthesia, where a stimulation of one kind of sense might trigger another kind. A person with synesthesia might taste an almond flavor then see a color of blue, or more directly they ..read more

Hi, I was wondering if anyone had some good material, books or any other resource that's not overly theoretical and has to do with Statistical Analysis. I'm currently studying for a Master's in Statistics and Computer Science and wanted to at least touch upon the real-life business applications before my internships. So what I'm looking for is a resource on Statistical Business Analysis that works with real-world examples and is at least somewhat up to date. Thanks for any suggestions. submitted by /u/Jakov123123123 [visit reddit] [comments ..read more

I once saw a post where somebody found several hundreds consecutive numbers down the decimal expansion of e or pi, which, when put one row below the other, looked like a photo of some mathematician, i think Riemann. Does anybody else know about it? I couldnt find the photo ever since and I think it's exceptionally beautiful piece of maths submitted by /u/Acceptable_Wall7252 [visit reddit] [comments ..read more
