What's That Mysterious Spot on Uranus?

Alex

All right, stop laughing.

In all seriousness, there is a mysterious spot on the gas giant. No, really. Discover Magazine explains:

Uranus, like the other giant planets in the solar system (Jupiter, Saturn and Neptune), is made up almost entirely of gas, although it differs in composition to Jupiter and Saturn -- it has higher quantities of water, methane and ammonia ices. Unlike conventional ice, it's a super dense liquid. Uranus, like Neptune, is often referred to as an "ice giant." [...]

An image taken by planetary scientist Larry Sromovsky, with the Gemini 8.1 meter telescope shows a bright patch that is thought to be an eruption of methane ice high in the atmosphere. [...]

Understanding the nature of this spot is important, Hammel explained to Discovery News.

"The reason we care about the clouds on the planet Uranus is that they seem to be seasonally driven," said Hammel. "Uranus spins tipped over on its side, giving rise to extreme changes in sunlight as its seasons progress.

"The changes are therefore much more dramatic than for other planets. Uranus thus gives us unique insight into the energy balance in a planetary atmosphere."

A good place to get your "i.e's" and "e.g's" right you should get the podcast called "Grammer Girl's Quick and Dirty Tips for Better Writing."

Good stuff, yo!

I specifically remember learning that i.e. can also mean "in exemplum," which makes that usage of it identical to e.g. Anybody know of a debunking of that notion?

For people, I use "et alia" (or "et al.") rather than "etc." It means "and others." I've never heard of "i.e." meaning "in exemplum," but a quick search via Google shows that this is a common (mis?)perception.

Reminds me of my favorite sequence from Get Shorty:

"Ray "Bones" Barboni: Let me explain something to you. Momo is dead. Which means that everything he had now belongs to Jimmy Cap, including you. Which also means, that when I speak, I speak for Jimmy. E.g., from now on, you start showing me the proper fucking respect.
Chili Palmer: "E.g." means "for example". What I think you want to say is "I.e.".
Ray "Bones" Barboni: Bullshit! That's short for "ergo".
Chili Palmer: Ask your man.
Bodyguard: To the best of my knowledge, "e.g." means "for example".
Ray "Bones" Barboni: E.g., i.e., fuck you! The point is this: is that, When I say "jump", you say "OK", okay?"

Shabby! Not only is a commenter trying to pull a fast one (with a phony phrase, "in exemplum," for "i.e."), but also the main post has an error in each explanation of three additional abbreviations,
(1) "C.f." should be "Cf." -- without the extra period.
(2) "Etc." is not "the abbreviation for "etcetera" -- but rather the abbreviation for "et cetera" (with a space between the two Latin words).
(3) "QED" is not the "abbreviation for quod erat demonstradum" -- but rather the abbreviation for "quod erat demonstrandum" (with an "n" before the second "d."
Tsk, tsk!
