I was watching a nature programme the other day, and saw the most amazing bird. It was an exotic bird, possibly a bird of paradise. Fairly small, black, but the striking thing it did was a weird courtship dance, where it lifted its wings up and held them over itself, and it had neon yellow markings that looked like a weird face against the black background. It was so weird, I want to find a picture of it but didn't catch what it was called!!! Any ideas?

I'm doing a Science Fair experiment on it. I think it'll work depending on where you drop the food.

Prove that the centroid of a plate triangle of uniform thickness, and the center of mass of 3 identical bodies, one at each vertice of the triangle, are the same point? Any short cuts to this besides looking up the formulas? Why are both the intersection of the medians of the triangle?

Sorry for asking a question and then answering it ... but this question was recently posted here, and I don't think anybody had the correct answer:

People all correctly pointed out that the Apollo missions went to the moon. But the comment was that since the moon orbited the earth, that the Apollo missions had technically never left the earth's orbit. I disagree.

It is unclear whether being in orbit around the moon is in fact also being in orbit around the earth. But I'm not talking about that.

But what is clear to me is that *while in transit* to the moon, the Apollo spacecraft was NOT in earth's orbit by any definition of the word "orbit." It had achieved escape velocity and had escaped the earth's orbit. Had the moon not been there to *decelerate* the spacecraft (and capture it in a lunar orbit), it was gone.

Anyone disagree? If so, why?
