Given the spirited postings from the recent math threads, I decided to ask a question I asked a while ago: How does one calculate the complex non-trivial zeroes of the Riemann Zeta function. I've seen various books about the Riemann hypothesis, but they all either assume you know how to do the calculation, or they simply state that the calculation is beyond the scope of the book. I haven't found any web sites that discuss how to do the calculation. Most simply discuss the existence of such zeroes, with maybe an example or to, but no computational issues are addressed.
