### 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. I understand the rationale behind the GPL, because it guarantees that any modifications to GPL'd code are contributed back to the community. The BSD license is not viral in nature, like the GPL is, but can't guarantee that further improv...

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.
