There appears to be some correlation between rain and pooping from trees, but it hasn’t been well-studied, to my knowledge. If it has, I’d love to see the paper.
Nevertheless, ground level sloth pooping seems to be the norm.
I’ve exhausted my expertise on the topic; I think the article I saw was in Smithsonian around 1993-4.
I just quoted this because it’s the most hilarious sentence I’ve read all day.
I aim to please.
From the tops of trees.
The symbols mean exactly what they are supposed to: the “+” terminal is at a higher potential than the “-” terminal. Nothing wrong about it.
hmm, perhaps I’m misremembering. I do know that several of the electronics books I own refer to the incident as The Mistake.
Back To The Facts
Besides common red, yellow and orange, amber comes in green, blue, opaque white, and opaque blue. Once while looking for a specimen of the rare blue types, I was told by a clerk ‘There is no such thing as blue amber. What you saw must have been dyed or something’ It is indeed taking longer than we thought.
Even more to the point, Columbus was trying to demonstrate that the Earth was much smaller than it actually is or was believed to be, even at the time.
This has no significance unless the sequence was specified before the deal. The probability of getting some sequence of 52 cards is unity.
You are likely thinking of the arbitrary choice of whether the charge on the electron was called positive or negative. It doesn’t matter which is chosen, though. Many common systems convey charge through the motion of electrons, and because of this some argue that the electron “should” have been conventionally labeled as having positive charge, but it’s really six of one, half dozen of the other. Neither convention is more right than the other. And as Crafter_Man mentioned upthread, electrical currents can involve the motion of positive charges, negative charges, or both at the same time.
I recall reading some time ago that on the scale of the Universe, certain very large numbers (e.g., the average distance between galaxies) tend to cluster around the number 10^64, while very small numbers (e.g., the average size of subatomic particles) tend to cluster around 10^-64.
Sound familiar, or is my memory flawed?
Now I see what you mean; the effect is a result of the mechanics of twisting the cable, not a conductivity phenomenon. Well, you say it’s difficult for eyes to see and I guess that must be true because I have never observed this. I also suspect that taking a straight-lay stranded cable and then twisting it may produce a different result than twisting the strands around a core as the cable is made.
Yes, it is a very subtle thing, and almost impossible for the human eye to detect. But it is there. And resistance measurements (between twisted and solid wires) prove this phenomenon is true.
Quite possibly.
Nor do you need the Coanda effect.
Lift is caused by directing air downward. A flat surface can do that, as long as it has a finite angle of attack. The advantage of an airfoil is that it allows a larger angle of attack before stalling.
There is a great tutorial on flight available here.
It only means that because we have arbitrarily decreed that + and - are the way round they are. :smack:
If “higher potential” meant “more electrons stacked up and ready to unload” then plainly the negative side, as presently defined, would be the side with higher potential.
Yes, that’s exactly what I’m saying. It’s an arbitrary convention, but the battery conforms to that convention, so there’s nothing wrong with the labeling.
Nothing rhymes with orange. That can be read in more than one way. One could be clever and say, false, nothing does not rhyme with orange.
I googled this some more, and found that the “only word in the 20-volume historical Oxford English Dictionary that rhymes with orange is sporange, a very rare alternative form of sporangium (a botanical term for a part of a fern or similar plant).”
How is this a science fact?
Titanium is like that as well. An interesting thing about Ti: it’s not expensive because it’s rare, it’s expensive because it’s difficult to refine and work with. Titanium dioxide is pretty cheap and used as an opacifier in paper, paint and even food. Another relation with aluminium, aluminium used to be more expensive than gold, also because it was hard to extract, but look where it is today. If we could find a cheap way to refine titanium, would it be as cheap as aluminium? (Maybe not that cheap, because titanium isn’t as abundant as aluminium in Earth’s crust)
Ah, I have committed heresy by forgetting that Cecil wrote about it! D:
I understood your joke, but I didn’t think that Psxer was joking.
