    Poll of Polls

    If each individual poll has a margin of error, when you combine all the polls, why do they say poll of polls has no margin of error? Shouldn't the margin of error get multiplied when you combine many polls?

    Physics snopes section

    After reading ZapperZ's recent insight, I think a physics/science specific snopes section could be an interesting idea (obviously the posting should be allowed only by selected people or after reviewed by a selected few).

    Sorry, this is a question on evolution. How did human female breasts evolve into such an important sexual organ? No other mammals other than humans seem to be interested in their corresponding female counterpart's breasts. They may be getting visually attracted, but do not seem to be interested...

    Can pull up exercise increase height?

    Can pull up exercise (at a younger age, say, before 15 years old) increase height? My guess is yes, since weight lifting could decrease height (Or that is another myth?) If yes, by how much?

    Feed all the laws into it and the robot and let the robot make unbiased judgements. Are human feelings necessary for a good court judgement? At least the first level judgement could be by a computer. If there is a dispute, it could be escalated to a higher human judge. Thoughts?
