Talk:Orders of magnitude (energy)
From Wikipedia, the free encyclopedia
I created this page to consolidate the information on the various 1 E* J pages. I think this format makes the information much more accessible and useful to readers. Future edits should probably concentrate on making it easier to scan and digest. See Orders of magnitude (length) for an idea (unfortunately I found that article after I created this one). There are similar collections of pages for length, area, volume and time — and probably others, but I gave up looking for them all. User:Onebyone was gracious enough to merge the info from the various "mass" pages into Orders of magnitude (mass). Below are the individual pages from which the information came (note that some are missing and some redirect to others).
- 1 E-31 J, 1 E-23 J, 1 E-21 J, 1 E-19 J, 1 E-18 J, 1 E-15 J, 1 E-14 J, 1 E-13 J, 1 E-12 J, 1 E-11 J, 1 E-10 J, 1 E-9 J, 1 E-8 J, 1 E-7 J, 1 E-6 J, 1 E-5 J, 1 E-4 J, 1 E-3 J, 1 E-2 J, 1 E-1 J, 1 E0 J, 1 E1 J, 1 E2 J, 1 E3 J, 1 E4 J, 1 E5 J, 1 E6 J, 1 E7 J, 1 E8 J, 1 E9 J, 1 E10 J, 1 E11 J, 1 E12 J, 1 E13 J, 1 E14 J, 1 E15 J, 1 E16 J, 1 E17 J, 1 E18 J, 1 E19 J, 1 E20 J, 1 E21 J, 1 E22 J, 1 E23 J, 1 E24 J, 1 E25 J, 1 E26 J, 1 E27 J, 1 E30 J, 1 E33 J, 1 E36 J, 1 E39 J, 1 E42 J, 1 E45 J, 1 E48 J, 1 E69 J,
Never had articles:
- 1 E-30 J, 1 E-29 J, 1 E-28 J, 1 E-27 J, 1 E-26 J, 1 E31 J, 1 E32 J, 1 E35 J, 1 E37 J, 1 E38 J, 1 E40 J, 1 E43 J, 1 E44 J, 1 E46 J, 1 E49 J, 1 E50 J, 1 E51 J, 1 E52 J, 1 E53 J, 1 E54 J, 1 E55 J, 1 E56 J, 1 E57 J, 1 E58 J, 1 E59 J, 1 E60 J, 1 E61 J, 1 E62 J, 1 E63 J, 1 E64 J, 1 E65 J, 1 E66 J, 1 E67 J, 1 E68 J
Now redirect here, to Orders of magnitude (energy):
- 1 E-25 J, 1 E-24 J, 1 E-22 J, 1 E-20 J, 1 E-17 J, 1 E-16 J, 1 E28 J, 1 E29 J, 1 E34 J, 1 E41 J, 1 E47 J, 1 E70 J.
See Talk:Orders of magnitude for more discussion. - dcljr 09:27, 29 Aug 2004 (UTC)
- I'm messing with dcljr's list above, grouping them as I weed them out, getting to here. Gene Nygaard 06:26, 22 Jan 2005 (UTC)

[edit] Weed-eat
This is a hopeless mess, useless as tits on a boar. It is extremely difficult to wade through by moving from one magnitude to the next with the navigation links on each, with little useful information on any page and no useful information on most of them.
I'd suggest changing it to only powers of 1000 in the middle ranges, with 1 E-6 J, for example, covering from 1 µJ to 1 mJ.
Then, at the both ends of the list, one broader category, covering perhaps 10-33 to 10-15 joule on the low end, and 1021 to 1069 on the high end (just suggestions for the neighborhood I'd have in mind. Gene Nygaard 22:07, 21 Jan 2005 (UTC)
- Now that all these separate pages have been combined here, they can all be made redirects to this page.--Patrick 22:48, Jan 21, 2005 (UTC)

- I'll start by deadening the links to nonexistent pages on this talk page. Hope I'm not violating protocol by messing with postings by dcljr, who appears to have had the same idea of eliminating the other individual pages in mind in starting this page, judging by what is said above.
- Then I'll look for others not linked to (other than from here or similar pages) and containing no real information. Maybe some of them can be deleted rather than making redirects?
- Then the ones that are linked to can be redirected here. -- Gene Nygaard 23:26, 21 Jan 2005 (UTC)
[edit] Error notice posted at ref desk
I have not made the changes suggested. I agree this is not a page I'd like to engage. Could one of you who watch it check this out? alteripse 14:48, 6 Feb 2005 (UTC)
[edit] http://en.wikipedia.org/wiki/1_E48_J
(Obvious) errors in the "Orders of magnitude (energy")- page, where at least two lines are not correct.
A.) Assuming the line 1.74 × 1016 J — total energy from the Sun that hits the Earth in one second is correct, then the line
B.) 6.2 × 1020 J — total energy from the Sun that hits the Earth in one hour would have to read: 6.2 × 1019 J — total energy from the Sun that hits the Earth in one hour
and the next in context should NOT be
C.) 1.5 × 1023J — total energy from the Sun that hits the Earth in 24 hours
but is either: C1.) 1.5 × 1021J — total energy from the Sun that hits the Earth in 24 hours
and would hence have to be moved upwards in the list, or (what would probably be of higher interest), should read:
C2.) 5.49 × 1023J — total energy from the Sun that hits the Earth in ONE YEAR
Commentary: The fact that the above two lines -lines, which, unlike most others, can easily be checked- are so drastically wrong, leaves the user with a rather unpleasant feeling: "How many figures are wrong too, resp., even worse, are there figures, which are correct?"
Who is capable of double-checking all these informations?

Thanks for noticing and taking the trouble. The answer to your question is "You are." Welcome to the community. Accepted procedure would have been to make the corrections in the article and put a note like this on the article's Talk page (where it says, "discuss this page"). Alternatively, if you don't want to make the edit, just put a note like yours above on the talk page. I copied your note to the appropriate talk:Orders of magnitude (energy) page. We'll let those who watch that page confirm and make your corrections. alteripse 14:48, 6 Feb 2005 (UTC)
[edit] The 2004 Indian Ocean earthquake?
In this article:
- 1.33 × 10^20 J — energy released by the 2004 Indian Ocean earthquake
In 2004 Indian Ocean earthquake:
- The total energy released ... has been estimated as 2.0 exajoules (2.0×10^18 joules). (http://earthquake.usgs.gov/eqinthenews/2004/usslav/neic_slav_faq.html)
I don't want to change it. There may be other numbers. -- Toytoy 17:05, Feb 6, 2005 (UTC)
- The largest ever underground nuclear test was the 5 megaton Cannikin conducted on Amchitka island in Alaska. (This test was the reason Greenpeace was formed). I thought I remember this test registering as a 5.9 magnitude earthquake, although google searches say 7.0. In any case, the Cannikin result gives an megaton == earthquake relation that can be used to estimate energy released in earthquakes. Jeff Carr 22:59, 21 January 2006 (UTC)
[edit] LHC
From the page: "2 × 10−4 J (1250 TeV) — Expected ion collision energy level of the Large Hadron Collider being built at CERN (2005)."
Uhmm isn't this way WAY high? I thought the center of mass energy for the LHC was only like 14 TeV....--Deglr6328 03:52, 21 Feb 2005 (UTC)
[edit] Need more magnitudes near origin
I'd like to see more energy magnitude examples near 0, such as 10^-1 and 10^2. Arguably, these are the most common magnitudes of energy perceived by most individuals in our daily lives, and perhaps the most useful as a reference. Presently, it goes straight from "small apple" to subatomic particles... 68.228.0.128 03:39, 28 October 2006 (UTC)
