After reading one interesting science paper last week, I'd like to hear opinion of someone experienced or who is "in the theme":
Modern processors have some finite level of precision, so what processors are used in nuclear physics or genetics, for example? What's their level of precison when we talk about numbers like 10e-19 (unit charge) or 10e-34 (Planck constant)?
Take a look at Gravitational constant definition @Wired.com, difference is about "240 x 10e-6". I am confused a bit, what kind of processors did they use?
"small changes in input parameters should produce correspondingly small changes in the output"—except for chaotic systems. ☺ – Paul A. Clayton – 2014-06-19T18:58:10.347
Even for chaotic systems, there is typically a scaling such that smaller changes in inputs produce smaller changes in outputs. Rounding errors generally appear different. Nevertheless, the expert needs to be aware of potential rounding errors, test for them, and compensate where needed. – sudoodus – 2014-06-19T19:24:49.990
