Partial Differentiation of Complex Functions. Hi: I am trying to find a good answer to one of my students questions: why, if f is a function of _one_ complex variable, can we meaningfully talk about partial derivatives.?. Partial derivatives make sense (at least in the real case) when we have more than one variable, e.g., f(x_1,..,x_n). But, if we hav... 16 Jul 2010 01:15
If Economics is one of the "Soft Sciences" how can it betrusted determine so much in society?

What is the difference between a value judgment and a fact (description vs prescription) I see many people try and disguise a value judgment as some sort of fact or just a value free description. How can one tell when someone is explaining some facts or just trying you to get interested in what he or she likes? You know, how some people insist that it is factual that certain kinds of music is better th... 18 Jul 2010 11:36
0-1 knapsack problem: uniqueness of optimal solutions Hello: This is a problem in theoretical computer science and algorithms. When solving the 0-1 knapsack problem using dynamic programming, how can you use the resulting table to determine whether the optimal solution is unique? The problem is the following: A thief is going to steal some items and put them in... 16 Jul 2010 12:08

JSH: Some math history After Gauss died in the mid-1800's, other mathematicians attempted to take up his mantle in various areas of number theory, and a lot of issues I'm currently discussing trace back to that period so it's worth a quick bit of math history, and I like to start with Riemann. Riemann decided to solve a bit of a myster... 16 Jul 2010 09:54
