Skepticism is not a position; it is an approach to claims.

I see, thanks Chas. why use it (zero) at all when dividing then?

Strictly seeking, mathematically, one cannot divide by zero, but there are many quantities in physics where this can occur, for instance QFT is plagued with these infinities. There are several techniques to deal with such instances.  (October 4, 2014 at 11:05 am)Deidre32 Wrote: I see, thanks Chas. why use it (zero) at all when dividing then? I like the sandwich idea. Why would you try to divide a sandwich between zero people and how would you know when you were through?
