It's a short story about the "Monte Carlo project" to randomly generate viruses. A pertinent quote:
The theory also included the best containment facilites in the world, and five hundred and twenty people all sticking scrupulously to official procedure, day after day, month after month, without a moment of carelessness, laziness or forgetfulness. Apparently, nobody bothered to compute the probability of that.
Especially his "Cabinet of mathematical curiosities".
"The music of the primes", by Marcus de Sautoy, is also worth reading.
I have found one problem with open source toolchans - producing good quality graphics. At the end of the day you have to present the data, and gnuplot just isn't cutting it anymore.
Try R instead. It's FOSS and the graphics are fantastic. (I haven't used Mathematica, but the 2D plots are better than Matlab's. You can also easily link it up to ggobi or Mondrian for visualising multidimensional data.)
