It can mean alot when you've been isolated long enough.

My 13 year old nephew has asked me to help with his science homework on electricity, which I'm not familiar with. Can you explain what I need to know. It would have helped if i knew what book he was working from but doesn't have one apparently. Click image to enlarge.

This is is a science forum, therefore, it is natural for us to see things that we discuss through the "lens" of the scientific method and expect participants here to do, or at least attempt, the same approach. "When in Rome...".

So, where's the evidence? If the NIH isn't conclusive about it how can you be? It's conclusion:

Spend some time on Physic Forums and then say this is over-strict. I'm not denigrating them because that's how they want it but they brook no deviation from the mainstream. It's my personal opinion that SFN staff give sufficient leeway without the general mission being lost in too much dross.

I fear your patience is wasted.

In the absence of anything, I suppose the most rudimentary clock is ones own internal body rhythm; rest time and active time

Photons.

The mods, on moving a thread, expect change on the part of the OP. If that action of moving it is not enough of a hint and the OP continues as they did before, why wait for more than couple of posts to lock it?

Yes, low frequencies are omnidirectional aren't they? You can't really tightly focus them like high frequencies.

It's on the same lines as the Khan Academy explanation: it's consistent with the rest of the ways mathematics is done.

Same to you mate.

If she wants to know what a jealous, obsessive and possessive person is like, that looks like a prime candidate to explore.

In a nutshell: The Lounge is not a place to to try and sidestep the rules that may be in place in the other forums. Edited for missing word

Seems like to me that you are misapplying highly technical terms and connecting them to fields where they don't belong. Like this: You pulled this out of where the sun doesn't shine.

Is skill related to innovation? If you don't have the skill how can you know how to improve it? As the guitarist Segovia once said "If you can't play it slowly, how can you play it quickly?" Both skills need to draw from imagination where existing knowledge may be permutated to create novel ideas or address novel problems.

Right. I'l look into that .Thanks. OK, thank you.

You won't find it, as written, because I composed it from knowledge I already had. I pulled the article up after to support it and give you some general info on them. It occurs when there is a steep enough temperature difference between the sunlit surface layers and lower aphotic water. http://oceanservice.noaa.gov/facts/thermocline.html

All classifications are artificial because reality is a continuum. It's our way of cutting it up into discrete parts so that we can make sense of it and talk about it

Interesting. I thought it was better for cell integrity to freeze as quickly as possible; smaller crystals. I learnt this reading about Birdseye who realised that fish frozen in the arctic temperatures i.e. really quickly, didn't go mushy when thawed.

Indeed. What does defeat feel like?

I was in the garden with my my neighbour yesterday who has a dog. We were chatting and said his Pug had been bingeing and eating aything over christmas and wasn't feeling too good from the gluttony. I noticed the dog went up to a single blade of grass, nipped it off then proceeded to chew it with apparent purpose. Didn't look like pica to me; it wasn't bored.

If we drive ourselves to extinction, is that information worth saving only to possibly infect some future intelligence with the same flaws; is a clean start not better? What we think is good for us may be bad for them.
