A pink granite inspection table here where I work comes up radioavtive when read with a gieger counter. The Geiger counter says beta emissions are coming from this table. When I scan the gray granite table the geiger counter reads almost nothing. Note: I don't know the level of radiation...

I've created a new html table of the nuclides that allows you to only show even, odd or every 4th nuclide making it easier to see patterns in the overall chart. See the image below. The horizontal axis can be either 'the number of neutrons' or 'the number of neutrons minus the number of...

Is anybody aware of how to solve the following infinite sum: \sum\frac{1}{n^2} for all positive odd integers? Is this the sort of thing you just look up in a math table or solve? If math table, do I need a "sum of reciprocal powers" table or a "riemann zeta function" table? If...

If the Cayley table, of a finite set G, is a latin square (that is, any element g appears once and only once in a given row or column) does it follow G is a group? I know the converse is true, and it seems reasonable that this is true. Since the array will be of size |G|x|G|, inverses exist and...
