Re: Margin of error when the sample percentage is zero?

Region of Reasonableness: x is a reasonable percentage if, given that it is x, the observation is not exceedingly unlikely. In this case, the math is really easy: (1-x)^n is the chance that on n samples you get 0 events. It is nicely monotonic, so once we find the point where it crosses our reasona...

Re: Assumptions that the Scientific Method makes?

why does so much of modern science rely on computers? To do it faster. I use computers to simulate diffraction patterns and to manipulate the model to fit the observed data. I could do all of that by hand if I wanted. Problem being it would take about a week per iteration, as opposed to several sec...

Re: GNU versus BSD

As I see it, the GPL and BSD licenses represent two extremes.

The BSD license is not viral in nature, like the GPL is, but can't guarantee that further improv...

Re: Mechanical or Electrical Engineering

Also, doing a double major in engineering in under 4 years? No chance.

A double science degree (both three years) takes ~4 yrs, a double degree BSc/BEng takes 5 years, so I'd say a full blown double degree BEng/BEng would take at least 5 years, probably 6, depending on the overlap.
