New draft Rosetta Code task and starting Python solution.

Take an integer n, greater than zero. Form the next n of its series by reversing the digits of the current n and adding the result to the cuurent n. Stop when n becomes palindromic - i.e. the digits of n in reverse order == n. The above recurrence relation when applied to most starting numbers n ...

No likely about it, but we are dealing with infinite length sequences here.

Vecina ljudi zna tablicu mnozenja sa 5, ali kada se radi o velikim brojevima, teze je izvrsiti takvo mnozenje.

Sljedeca tehnika je jednostavna.

Dati broj podijeliti sa 2, a zatim pomnoziti sa 10. Ako dati broj podijeljen sa 2 daje cijeli broj dodamo samo 0 (nulu), a ako ne zanemarimo zarez.

2682*5=2682/2*5*2=1341*1=13410

5887*5=5887/2*5*2=2943,5*10=29435

All are easy to understand with little effort, except the last one, even I can prove it :).

Realization of sieve of Eratosthenes can calculate p<x and p>x part proportion to power of z(n), Bernoulli numbers time s!^2/n! in Pascal triangle can get next one, include odd one, equation similar one from random matrix, 8640 close to 25740/3, 24024 close to 25740, Bernoulli numbers can use sequence of golden ratio express by continuous fraction, even show up in SR, M=m/(1-(V/v)^2)^(1/2), let m/M=V/v=x get x^2+x=1 equation of golden ratio, can turn into x=y^2-(-1)(y=x*i) fractal equation of chaos but have order in it like random matrix of energy level of atom which be represent by nontrivial zero which are reverse of trivial zero which have nice ordered equation 2*n^2 for single atom(C*H=E*R). nature hide it's true face pretty well, at final golden ratio is it's ultimate law.

On Optimal Ordering of Service Parameters of a Coxian Queueing Model with Three Phases

We analyze a Coxian stochastic queueing model with three phases. The Kolmogorov equations of this model are constructed, and limit probabilities and the stationary probabilities of customer numbers in the system are found. The performance measures of this model are obtained and in addition the optimal order of service parameters is given with a theorem by obtaining the loss probabilities of customers in the system. That is, putting the greatest s...

How many times have you read the names of a Mathematician in a book or online and wanted to do justice to their pronunciation?

Maths student, Andrew Marcinkiewicz (who is on G+), has produced a helpful guide to the pronunciation of names of famous Mathematicians alongside some of their most notable theorems and lemmas. He includes an audio file and the International Phonetic Alphabet (IPA) code for each one on his blog.

Hi, Math Enthusiasts.

I found again today, that the awareness about mathematical concepts is somewhat arbitrary.

I think every scientist has to comprehend everything completely, making it very difficult to advance to a certain state.

The comprehension in particular is bothering me.

e.g.: Newton might have been much more advanced in his theories, than we can comprehend !

Does anybody share that thought?

In particular theory of relativity is not really a new thing. It is rather just a concept within the frame of newtons mathematical groundwork.

What is bothering me is, if newton figured out much more than anybody would be able to comprehend; then we barely touched the surface of higher concepts. Which are of course only valid in his mathematical system, which could be superior to others...

I have found a method to represent a word clearly and distinctly with a single numerical identity. For a particular word will have a particular numerical identity. The method to determine a sentence with a single numerical identity is in process.

Oh, it is a sort of computer term. I'm not sure how it works, but they feed the input data into a system which outputs a unique number that is specific to the input provided. It's used for encryption stuff mostly. I was kinda jokingly tossing that out there.

Maybe a checksum is more appropriate to what I was talking about, but that is where you read all the bits of a big file, and I guess they add it all up to produce one "sum" value which represents the file, and if any single bit of the file is different from the original, the checksum values differ and you can tell that there was a problem with a transfer or something.

I had not read your notes when I commented. It looks like you have put a lot of thought into the system you came up with, I hope you catch the eye of someone who can really interpret and appreciate what you are trying to say there.

Here is one explanation of "hashing" that I found: http://www.webopedia.com/TERM/H/hashing.html

An idea:

Can the sequence used in the**Collatz Conjecture** be reduced to a sort of a sequence similar to the *Goodstein Sequence*, from which some extension of *Goodstein's Theorem* may be used to imply the Collatz Conjecture?

Can the sequence used in the
