 Nov 7 comment Is possible to determine the biggest number in universe? Yes, please move it to math.se, infinity is not a number. Oct 27 comment Largest prime number with all digits different One of course has to show that this number acually is a prime and the other two aren't. What would be the quickest way to do it? Jul 1 awarded Critic May 16 comment How to find the best interpolating function if we know $y(x_i)$ and $dy(x_i)/dx$ Big thank you! Very nice of you to share these references! May 15 comment How to find the best interpolating function if we know $y(x_i)$ and $dy(x_i)/dx$ Thank you! Indeed, rather simple and natural an approach. Do you know, what ideas are there behind when chosing $\beta_1$ and alike? Jan 2 awarded Notable Question Dec 24 awarded Nice Question Oct 22 awarded Commentator Oct 22 comment Can one define informational content of a mathematical expression? @AbdulhKhazzakGustavElFakiri: Nevertheless, the concept of encoding seems so much more obvious, when applied to strings, rather than exressions. Latter tend to have a complex underlying structure. Saying 1.0000.. is not the same as writing all the zeros, for example. Here you use a convention, that zeros continue. Oct 21 comment Can one define informational content of a mathematical expression? @AbdulhKhazzakGustavElFakiri: So, is it meaningful to assign the concept of information to an expression? And why does the informational content of an expression (seemingly compact) seem to differ so much from that of an irrational number (seemingly infinite)? Oct 20 comment Can one define informational content of a mathematical expression? Dear @AbdulhKhazzakGustavElFakiri, your link is really interesting and somewhat relevant to my question. However, it is far from obvious to me, how exactly does it provide the answer. Can you please kindly state it more explicitly? Oct 11 comment Can one define informational content of a mathematical expression? @Potato: Indeed looks very relevent. Thank you (10^10 times)!

May 15 comment Links between difference and differential equations? Mostly I am interested to know if it is possible to reformulate ones in terms of anothers, but more general possible studied relations would be also interesting.
