JSH: Understanding your worth
To me knowledge is not something that is a birthright. It does not matter to me if most of you die in ignorance, or not. But for your lives, if you do any mathematical work, does it matter if it's wrong? Does it? An experiment is in progress: how valuable is your time, really. If I am right, then the ans... 10 Feb 2010 22:28

About transportation problem
Is transportation problem generally solved, so there are no big problems to solve it now? For ex., if some data are subdetermined (lie in some interval [a,b]), is it also difficult to solve them with modern methods? Can someone give a system of constraints (Constraint satisfaction problem) related to transportatio... 12 Feb 2010 20:14

existence of real root(s) of a transcendental equation
Hi, Is there an algorithm for checking the existence of real root(s) of an arbitrary (uni-variate) transcendental equation (not polynomial equation)? I'd appreciate it if you can provide references to the algorithm or the proof of the non-existence of such an algorithm (if either of them exist). Thanks. Simo... 10 Feb 2010 00:09

JSH: NSA is listening to you
JSH has been threatening for several years to release his factoring algorithms to "third parties" that will cause complete financial collapse. Well, the Financial collapse happened. JSH continues to threaten the world with his math, a technical terrorist. NSA is investigating with great vigor all possibili... 8 Feb 2010 14:32

Conditions to Have Mean=Median
Hi, everyone: I am trying to see what the necessary/sufficient conditions on a distribution , to have the mean equal the median. It seems like symmetry is at least sufficient; the normal distribution obviously has this property. In general, it would seem that if there is a value ... 8 Feb 2010 03:27
