Magic Definition and 109 Threads

"The arrangement of numbers with n rows and n columns to be a true magic square is that it contains all the integers 1, 2, 3, n(squared)" What does this mean? I have to write a program that checks to see a n rows and columns is a magic square, how do I check for this?

Greetings, I suppose all of us have at one time or another been fascinated by "magic squares" My question is: has the relationship of numbers in a magic square been found to be useful in the mathematical sciences in any advanced analytical work? Or is is just a mathematical curiousity?

This thread is not to be here (it is not speculative, nor it proposes any alternate theory, not it gives hints about building one). It was moved from "nuclei & particles". I have tryed to delete it, but the system does not let me to do it. In any case, the preprint is already out, it can be...

New Geometrical Polar-Ring Solution for Magic Numbered Nuclei. It is well known that if the neutron- or proton number within atomic nuclei have the following quantities (2, 8, 20, 28, 50, 82 and 126: the magic numbers), then the atoms are showing a more than average stability. As an example...

This is related to the Banach-Tarski paradox. One of the sites mentioned in that thread has a beautiful "experiment" on equidcomposability: Let A be a unit circle, and B be a unit circle with one point missing. It turns out that you can divide B into two subsets, rotate one of them, and then put...
