 Jan 20 comment Is there an interval that contains more squares of primes than primes? Sorry, didn't mean to "spank." I probably should have said, "Maybe there were additional constraints that you meant to describe?" Jan 17 comment How to parameterize an orange peel This answer was given a long time ago, but I'm curious... would a loxodrome really "start in (0,0,−1) and end in (0,0,1)"? Looking at the linked article on spherical spirals, it seems that those curves never quite reach the poles. Jan 17 comment Is there an interval that contains more squares of primes than primes? Trivially, yes. Any interval where $a = p^2-1$ and $b = p^2+1$, for some prime $p$. Oct 28 awarded Notable Question Oct 3 comment Mean Inequality @BjörnFriedrich: please be careful, when editing a post, not to change the meaning of equations unless it's really obvious the OP meant something different from what they said. Jul 24 awarded Nice Question Jul 18 comment what size is a “unit torus”? Interesting answer ... thanks. Jun 17 revised What's the smallest number with first digit 1 that triples when this digit is moved to the end? clarified title: "put in" sounds like maybe it means "appended" Jun 17 suggested approved edit on What's the smallest number with first digit 1 that triples when this digit is moved to the end? Jun 1 awarded Yearling May 25 comment Identification of a quadrilateral as a trapezoid, rectangle, or square I would be curious to ask, (1) why and (2) how was she "publicly humiliated" in front of the class? (1) How did she present and argue for her answer? If she did that badly (e.g. arrogantly, confrontationally, or tactlessly), then this would be an important learning opportunity for her. (Not that it excuses the teacher.) I've been in that boat and had to learn the hard way. (2) Do you mean someone intentionally insulted and shamed her, or do you just mean she was embarrassed because people concluded she was wrong? The former is a real problem; the latter, more of a life lesson. Mar 14 comment Why do 4 circles cover the surface of a sphere? A "plate" here just means a very short cylinder, right? Mar 14 comment Surface area of quarter of a Sphere What did you use to make the diagram? Jan 7 comment Is arrow notation for vectors “not mathematically mature”? Maybe not the only question, but I agree that clarity is much more important than projecting a professional image. Jan 7 comment Is arrow notation for vectors “not mathematically mature”? While this answer is true, I don't think it's an answer to the question asked. Dec 8 awarded Caucus Nov 25 comment The number of the circles which are tangent to two circles and to a line Are the two circles allowed to be tangent to the line? (I don't know if that changes the answer.) Jul 2 awarded Curious May 27 comment What is mathematical research like? @DisplayName, can you explain why the mathematician has hope of finding the cat? As opposed to, say, a physicist, an engineer, or an animal trainer. I'm not seeing it. The mathematician is well-versed in logic and proofs, but this won't help find the cat in the complete absence of empirical data. I think we're straying from the original point, but since I don't understand the original point it's hard to get back there. Maybe the search for the meaning of this quote is like a search for a cat that doesn't exist. Feb 18 revised What is wrong with this equations? attempting to improve wording
