How Magnets Work

OK being the repository of the worlds knowledge, you might think this one would be on Wikipedia.

You would be wrong.

If you type it in you get a horrible choice between the the Insane Clown Posse song Miracles and the article called Magnet.  

There is no page called How Magnets Work.  Not even a redirect to someplace that explains this.  http://en.wikipedia.org/wiki/Force_between_magnets would probably be the best place for a redirect.

Using a search engine online should answer the question, if your question is actually "How is a magnetic field created?" From  http://www.howmagnetswork.com/
How is a magnetic field created?
When current flows in a wire, a magnetic field is created around the wire. From this it has been inferred that magnetic fields are produced by the motion of electrical charges.
But what most people want to know is how does a magnet attract certain metals?  Or, how does a magnet attract or repel another magnet?  What is happening in the space between magnets that causes them to act as they do?

Skeptic

Skeptic

Mind blown.  There is no article for skeptic.  So of course I check atheist.

You won't find skeptic or atheist on Wikipedia.  How is that even possible?

meta musings

Do you know of something not found on Wikipedia? Do you care?  Would you start a blog to document these things?

The "Skeptical Movement"

I know it exists.  In fact it is used on Wikipedia (and elsewhere), but there is no definition or article for it on Wikipedia.

What is the Skeptical Movement?  Usually I link to at least one good source for something not found on Wikipedia.   This one seems to not have a definition that is scientific in nature.

Temperature of the sun

You won't find the Temperature of the sun on Wikipedia.

This isn't a mystery, as nobody actually knows the temperature of the sun.

 Not that there isn't a lot of speculation and information about the sun, and the various temperatures involved.

The center might be around 15,700,000 kelvin, the Photosphere we are pretty sure about is exactly 5,778 kelvin, and the Corona around 5,000,000 kelvin.  (which means the temperature rises as you leave the surface, a lot)

This all has to be true, because it is on the Wikipedia article.

It still doesn't tell us the temperature of the sun. But this is understandable. as nobody knows the temperature of the Earth either.

Evidence Based Science

Evidence Based Science has no entry on Wikipedia. (I made it up years ago, after seeing the term, Evidence-based medicine being used).

Evidence-based medicine is defined as "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients".

Makes you wonder, what other criteria would be used in making decisions about patient care? Money? Profit? Guessing?

 Not going to go there.

 However, many years ago I started a blog about Evidence Based Science but you won't find it on Wikipedia either.  I did find 14 instances of the term evidence based science being used on Wikipedia.  It's just never defined there.

Winter of 1933-34

This one might exist somewhere, but it's certainly not showing up.

Winter of 1933-34

Nobody can argue there wasn't a winter, and it's certainly notable.  It was by far the coldest winter in the north east United States, since records have been kept.  It was notable in New England and New York for the devastating effects on the apples. source source source source

Do winters show up on Wikipedia?  Yes, yes they do.  http://en.wikipedia.org/wiki/Winter_of_2009 which redirects to http://en.wikipedia.org/wiki/Winter_of_2009%E2%80%9310_in_Europe certainly exist.

http://en.wikipedia.org/wiki/Winter_of_2009%E2%80%9310_in_United_States does not.

Winter of 2009-10 in the US?  No.

Does Winter of 1933-34 exist on Wikpedia?
