Oberth effect

I hope I didn't give offense: I only replaced the explanation because I was certain I was right. The paradox does need a resolution.

The potential energy difference does not explain the effect. Consider a modified version of the example I give on Oberth effect, where the difference in speed comes from the speed being invested into potential energy, that is, the spacecraft was moving away from some mass. We now have two different cases. One, the rocket at a certain distance from a mass moving away from it below escape velocity, two, the rocket after its speed has reached zero, converting all of the speed from case one into potential energy, 1/10 of which was invested into the propellant. It started with a speed of 9. We don't need to know the size of the mass or the exact distances. A speed of 9 gives initial kinetic/potential energy of 81, 8.1 of which is held in the propellant. The rocket fires in the same way as in my previous example, and kinetic energy is assigned in the same way. Potential energy does not change because nothing has changed its height. We still have an 89.1 difference in kinetic energy of the rocket between the two cases, and the difference in potential energy of the propellant is 8.1 between the two cases, insufficient to explain the effect.

Well... the Oberth effect only happens when there is a change in potential energy. Your explanation doesn't cover potential energy, so is clearly incomplete. The kinetic energy of the propellant is generated from potential energy before it gives it up that energy to the body of the rocket, so the ultimate source of the energy is potential energy. In some cases the vehicle can have no significant initial kinetic energy until it falls close to the gravitating body.- ( User) Wolfkeeper ( Talk) 04:13, 25 February 2009 (UTC) reply
Sorry for not replying quickly, I've been away for awhile. The Oberth effect absolutely requires a change in kinetic energy, and this is almost always due to a change in potential energy, however it is not required: The kinetic energy could come from another supply of kinetic energy, such as after a collision, or a transfer from a skyhook-like device. My example above does in fact cover potential energy: I refer to the change in both the potential energy of the propellant and the rest of the craft, and it is not sufficient to explain the change in kinetic energy. The difference between the kinetic energy of the rocket between the two examples is 89.1, the difference in potential energy of both the propellant and the rocket is only 81, it is the difference between the initial kinetic energy between the two examples. The first example has a potential energy of 81, the second kinetic energy of 81 instead (it's the rocket if it had fallen and then used its engine).
I think I had already satisfied you that the potential energy of the propellant alome could not provide the energy, the equations are clear. I am surprised you reverted the article to your old version. Unless this argument convinces you, I think we need to ask for arbitration. Wingedsubmariner ( talk) 05:12, 1 March 2009 (UTC) reply
Sorry, arbitration means something else...I mean "dispute resolution", as described at Wikipedia:DR. Wingedsubmariner ( talk) 05:22, 1 March 2009 (UTC) reply
Sorry, you're simply talking nonsense. First you need to analyse everything in an inertial reference frame- we'll use Saturn. If the vehicle is travelling at 5 km/s and falls in towards Saturn and gains 20km/s, it then fires a thruster that emits exhaust at 3km/s relative to the rocket. It would leave the exhaust moving at 22km/s; whereas if it applies this burn in mid-space then the propellant would be left at 2 km/s; if it applies this close to saturn. The propellant has *more* kinetic energy when fired close to Saturn than when fired away; as does the rocket, and the rocket, when it has left the planet will be moving much faster than if it had applied it in deep space. The reason is that the potential energy of the propellant ends up much lower in the first case than the second, and the rocket was able to benefit from that.- ( User) Wolfkeeper ( Talk) 14:08, 1 March 2009 (UTC) reply
Yes, but it is the change in total energy that matters. 5 -> 2 means 25 - 4 = 19 change in potential energy, or 19, whereas 25 -> 22 means 625 - 484 = 141. Close to the planet the propellant loses more kinetic energy. It gained kinetic energy for its potential energy when falling into Saturn just as the rocket did, and still has this energy, less the 141 lost as a result of the rocket.
The Oberth effect also works when slowing down a rocket. Firing the engines to slow down the rock in this case gives 5 -> 8 which means 25 - 64 = -39 as compared to 25 -> 28 which means 625 - 784 = -159. In this case, the propellant gains more energy despite being expended lower in the gravity well.
The Delta-v page gives a good description of the dependency on speed and direction of speed: "when applying delta-v in the direction of the velocity the specific orbital energy gained per unit delta-v is equal to the instantaneous speed." Wingedsubmariner ( talk) 15:41, 1 March 2009 (UTC) reply
I copy and pasted our discussion onto Talk:Oberth_effect#Disagreement_over_explantion_of_paradox, can we continue it there? I added a request onto the WikiProject Physics page for help settling the dispute. Wingedsubmariner ( talk) 16:26, 1 March 2009 (UTC) reply
Sure, but they're not going to agree with you. The problem is you're only looking at one side of the coin. The Oberth effect isn't simply that rockets gain/lose more speed when their velocity is high; it's that you can gain/lose more speed by plunging into a deep gravity well. Or at least, that seems to be the way the term is used currently.- ( User) Wolfkeeper ( Talk) 16:57, 1 March 2009 (UTC) reply

Insert passive-aggressive subject line here

If the first line of an article gives an inaccurate description of what the article is actually about, I would consider that a fault of the article and not the person reading it. (Also, conforming a disambiguation page to guidelines in the face of someone who doesn't appear to understand those guidelines is not edit-warring.) Propaniac ( talk) 15:40, 8 March 2009 (UTC) reply

I would consider it a fault of the editor if they edit war, and this clearly was. When an article is on synonymous usages, which in general they are, then the first sentence cannot necessarily capture the whole topic.- ( User) Wolfkeeper ( Talk) 16:25, 8 March 2009 (UTC) reply
You might also like to look up the term 'passive-aggressive', you don't seem to know what that means, either.- ( User) Wolfkeeper ( Talk) 16:25, 8 March 2009 (UTC) reply
Okay, seriously, I have to ask since you apparently know: how can one person edit-war? If you can provide a satisfactory answer, I'll applaud you with only one hand.
Also, apparently you can capture the whole topic with one sentence in this case, since your preferred version of the disambig page was still able to summarize the topic of the linked article with a single phrase. If you think the topic of the article is X, it doesn't make sense to begin with "Originally, glamour meant Y" and then get around to mentioning X several sentences later. A better beginning would be "Glamour is X. The word originally referred to an item, such as jewelry..." blah blah blah. Your version is like beginning the article about the film Titanic with "The Titanic was a huge passenger ship" and not mentioning the movie until the second paragraph.
In regard to passive-aggressiveness in section titles such as "Sigh," let me see. A sigh is a fairly passive act. The implication, however, that you're sighing to express your immense weariness from dealing with foolish incompetents who expect that an article's opening will mention what the article is actually about? I would call that aggressive. Perhaps you could have saved yourself some heartache by simply including a more helpful edit summary on the dab page, such as "The article begins by talking about items but goes on to discuss this more general definition." But instead you chose to point out (as if I would have any reason to know or care) that you wrote the article's misleading introduction yourself. Well, to each his own, but you might have saved yourself some oxygen. Propaniac ( talk) 23:15, 8 March 2009 (UTC) reply
Unfortunately, that's not what the term 'passive aggressive' means. I'll get back to you with what it is.- ( User) Wolfkeeper ( Talk) 23:35, 8 March 2009 (UTC) reply
Well, perhaps you've been as busy as I am over the past two days and haven't had time to check in on Wikipedia either. But since the definition of "passive-aggressive" could not be further from the real point of my last message, I don't mind your failure to enlighten me.
I think there's little point in prolonging this discussion much further, but I do want to reiterate the following facts:
  1. I made a mistake, due to a combination of my failure to check the linked article as well as I should have, the failure of the linked article to be as clear as it should be, and my being accustomed to cleaning up edits on disambig pages by people who have no idea what they're doing.
  2. Since you understood the mistake I had made that had led me to revert your changes, you could have tried to politely explain the misunderstanding in an edit summary (as I attempted to do, in this diff, when I thought you were the one making the error). If you had, I doubt there would have been any need for us to correspond further. Instead, you chose to leave me an indisputably obnoxious note (regardless of whether the subject line was passive-aggressive or not) on my talk page accusing me of edit-warring (which was a ridiculous accusation, as I implied above; if you had pointed out my mistake and I had said "I don't care" and continued to revert your changes, that could have been edit-warring, but I was clearly acting in good faith and assuming the same of you).
I suppose that's all I have to say about the matter, and hopefully all that I will be saying. Propaniac ( talk) 02:15, 11 March 2009 (UTC) reply

Hash tables: order of sections

Hi there. About hash table: would you consider rearranging the sections in the order "Uses"/"Advantages+Drawbacks"/"Algorithms" ? That order seems better matched to the readers' interests. Namely, for each implementor who wants to know the algorithms, there is likely to be 10 readers who need to choose between hashtable package or or other structures, and 100 readers who meerely want to know what is a hashtable and what it is good for.

Right now, the article doesn't even cover the algorithm properly, somebody who doesn't know the algorithm will find it fairly difficult to understand. That's really bad.

Hi Wolfkeeper. We've had many discussions over the past 12 months about the applicability of Newton's Second Law to variable-mass systems. Please see the discussion page section called "Constant mass? Special case?" and the article section on open_systems (in particular references 17 and 18.

It's wrong, and harmfully so.

The article, after merger was over 85k. I kinda doubt that you would be able to remove 2/3 of the article without losing something. The fact is, the articles were already split, and that split was self-evidently consensus.

The split was done in the same way as my merge was. See Talk:Copyrighted_content_on_file_sharing_networks#Article_creator.27s_note. This removed a very large chunk of content from the file sharing article. While something like file sharing in Canada deserves its own article, the legality of file sharing in general is probably the most important issue in file sharing as a whole. Before I made significant edits to file sharing (I think over a month ago), the gap left by the split was filled with all sorts of uncited, pov, and OR stuff on the subject of the legality of file sharing. The articles need cleanup (or do you disagree?). I'm willing to do that cleanup. If you don't like how I'm doing it, please join me and we can work together. But don't just revert a bunch of work that is obviously in progress, and then walk away.   M   22:32, 14 June 2009 (UTC) reply

Whilst the reasoning for reverting 15 edits on this article may have been valid, I was slightly surprised to see no description of the change given, as well as slightly disappointed to see you had not noticed edits by other users in addition to those of M's that you contest. For example, I removed a cyclic link to a page that just re-directs to the original topic, but after your revert this was added back in. I'm sure this wasn't deliberate, but as a fairly an extremely new user to editing Wikipedia, it would be easy for me to get put off making edits if I thought they were going to be reverted without checking to see what they were.

It was impractical for me to go through all the edits and reapply them, and the longer his edits stood, the worse it would have been. The editor involved was unilaterally making major changes to the wikipedia, the quality had suffered, and he was violating a whole slew of the wikipedia's guidelines.- ( User) Wolfkeeper ( Talk) 02:52, 16 June 2009 (UTC) reply
At one point, you apologized for not being motivated enough to 'save' those edits. After a somewhat minor disagreement, your position has reversed, and you have been reverting when possible, without regard for the work others have put in. This isn't about me and you - when you revert, you don't undo "my work", you undo improvements to the article - who cares who made them. If someone makes a mistake (which they say they will correct!), this doesn't give you license to undo all the other changes to the article just to make a point, especially the changes of other editors. It would have taken you an extra 30 seconds - much, much less time than it takes other editors to make their changes.   M   17:47, 16 June 2009 (UTC) reply
I will always revert to an earlier article if that earlier article is higher quality than the current one; I will not, in general, reintroduce others edits in that situation, that's their problem.- ( User) Wolfkeeper ( Talk) 19:17, 16 June 2009 (UTC) reply
There are a bunch of other editors trying to work on articles, so unfortunately it quickly becomes your (our) problem. Some minor consideration for their edits would have made this entire section unnecessary. Anyway, would you mind having a look at my recent individual edits to file sharing, starting with this one? I'd like to run them by you before continuing to work on that article, in case you have objections. If you do, please let me know and we can work them out.   M

Cars with Turbojets

There are some dragsters and land speed record cars with turbojets, there are equally few roadworthy cars with turboshaft gas turbines. To claim from this that "turbojets have been used for cars" is vague and wilfully misleading in a way that's unacceptable in an encyclopedia.

If you're determined to describe jet cars here (which are so rare they have almost no place in an article on turbojets, see WP:UNDUEWEIGHT) then at least make this a decently clear paragraph that clarifies how rare any gas turbine cars are, and at least draws the distinction between gas turbine, turboshaft and turbojet. Andy Dingley ( talk) 16:31, 19 August 2009 (UTC) reply

Don't be an idiot. They're not that uncommon, and never have been. I live near a drag strip, I hear them firing up every few months. You know of Richard Hammond? Guess what he was driving when he nearly died?- ( User) Wolfkeeper ( Talk) 16:37, 19 August 2009 (UTC) reply
No-one is questioning that there's at least one jet dragster in the world, which means that "turbojets have been used for cars" isn't demonstrably false. However it's still inappropriate for that statement to appear in an encyclopedia, without further qualification. It would cause confusion amongst readers, which is bad. In particular, we would need to make it very clear that "jet cars" like the Chrysler Turbine Car or the more outrageously styled examples like the Fiat turbine car or the General Motors Firebird have never used turbojets.
Incidentally, if you're going to note an example of an LSR jet car, then rather than Thrust 2 I'd suggest either the first Spirit of America or the Green Monster as the most notable of the lot. Andy Dingley ( talk) 16:57, 19 August 2009 (UTC) reply
Add one of those as well if you want. Thrust2 held the world record for 14 years though, none of the others came close to that.

Not sure what you want for proof. Would having Prof. Soljacic email you help? I have emails back and forth from he and I. I sold his group the domain name and any rights or interest in trademark, etc..., which I had registered as part of a project to trickle charge cell phone batteries using a ladder of capacitors connected to a rectifying antenna. As far as I know the name is now a trademark. I did not add the wikipedia entry - had always assumed he had because in the sale I had expressed interest in wanting credit for coining the term. —Preceding unsigned comment added by David.gerding ( talkcontribs) 02:30, 9 September 2009 (UTC) reply

Wolfkeeper, I was just editing the page again. As I indicated, I have email records to prove the claim - which, while I don't want to publish I am happy to forward to you. More importantly, www.archive.org shows the domain name witricity active in 2004 (I registered it January 6, 2004 at domainbank.com and have the email receipt to prove it. Your diligence is cool... it actually helped me drag up the documentation to substantiate the assertion.) I will add a link to the www.archive.org wayback that points to the domain name being active by their measure as early as March, 2004. Hope this helps. Going back in and editing again. —Preceding unsigned comment added by David.gerding ( talkcontribs) 15:21, 9 September 2009 (UTC) reply

To be honest even if you could prove that, it's of peripheral interest at best. The WiTricity article isn't about the word 'WiTricity' it's about a particular type of resonant power transmission. The etiology of the term used for a different wireless system would be better off being covered in wiktionary; but I warn you, they also require references, and what you have so far proves nothing. Even if you were the one that registered the domain, that still doesn't prove you coined it (although it may be evidence towards that). You actually need something that says you coined it in so many words.- ( User) Wolfkeeper ( Talk) 16:13, 9 September 2009 (UTC) reply

Since you seem locked in on this, what's verifiable to you? I hope you noted that in the progression of way back machine thumbnails, my own company's site became the destination for the witricity domain. There aren't publicly linkable versions of the domain name record, though I can send it to you directly. This is a bit weird to me. I have the earliest "documentable" use of the word. Will you tell me an acceptable way to present that to you, since you are the one that seems to be disputing it? I'm sincere in asking for help here. Thanks. —Preceding unsigned comment added by David.gerding ( talkcontribs) 16:25, 9 September 2009 (UTC) reply

I'm going to respectfully disagree a bit about the naming issue, since the notion of witricity as a portmanteau has been in the article for a long time - and someone since added the additional information that it's a pending trademark. You've left in the WiTricity coporation's claim to have invented the word - but I think I've already provided usage documentation that precedes theirs. Since I believe that the term is likely to become a household name, I did in fact want to be credited for it. I always assumed that someone from MIT added my name as a nod to me - and I admit I was grateful and pleased. —Preceding unsigned comment added by David.gerding ( talkcontribs) 16:31, 9 September 2009 (UTC) reply

I think there is a strong argument though that this shouldn't even be on this page- that use of the term is about a different, non synonymous topic; resonant wireless transmission is not synonymous with microwave beamed power. However, provided you can get it down to one sentence and get really, really solid references then it's probably just about OK.- ( User) Wolfkeeper ( Talk) 16:40, 9 September 2009 (UTC) reply

Accelerated electrons

See my delayed answer in Talk:G-force. Basically, the radiation seen FROM a cyclotron electron DOES depend on jerk as seen in the inertial frame. Even if you're in an accelerated constant V frame where you see a constant acceleration around a circle, the radiation you see from the electron still comes from the Euler retarding radiation reaction force: see the cyclotron section in the special relativity article: http://en.wikipedia.org/?title=Special_relativity&section=16. If you (de)accelerate dw/dt tangentially to match THIS, so you're at rest to the electron, you no longer see it radiate (not all frames need to see an accelerated electron radiate-- accelerated frames where it is at TOTAL rest, obviously will not!). The same is true if you sit next to it in a g-field. S B H arris 02:50, 22 September 2009 (UTC) reply

Resolution

You blanked your reply before I was even able to see it, but I wanted to at least reply myself. The thing is that I completely agree with your view. Dictionary articles should not co-exist on Wikipedia (they have Wikitionary anyway!). This isn't about the substance of the document(s) at all! WP:NOT is a hard edged policy, absolutely. It's used all of the time, and that's proper. WP:NAD supports WP:NOT, and that relationship isn't going to change simply by marking it a "policy". It's a guideline on how to implement one aspect of the WP:NOT policy. These claims about "weakening" it are just... silly!

Right, I agree, I just don't see how that changes anything. That doesn't seem to be a distinction that matters to users (based on the usage and watchlist numbers). I don't see how labelling WP:NAD is a "demotion" or "weakening" of the document at all, and I would say that correctly classifying it as a guideline directly supporting WP:NOT should actually lend it additional credence. The statement "Wikipedia is not a dictionary" alone is something I would classify as policy. The rest of the material in WP:NAD I would classify as guidance on how to apply that policy statement. I think that the current relationship between the two documents is actually perfect (and they are both very well written for policy documents) except for the fact that the label is wrong on WP:NAD.

Hate sex

I put that amount of work into finding sources, I argue against most of the proffered deletion rationales, I write a Wiktionary entry on the term, I suggest moving the article to the Article Incubator - which is not deletion - and you think I'm trying to be a deletionist?! You're getting me wrong. I would like to write a coherent article on the topic, but we need decent sources in order to do this. The current article content, "It is related to the fact opposition between two people can heighten sexual tension, attraction and interest. The polarity[clarification needed] generated by a man who demonstrates comfort with, and lack of neediness for, a woman by verbally pushing her away, even playfully teasing her and issuing negs[clarification needed] (similar to the Mystery Method) can play into this" is pretty pathetic and is pure original research; the sources just added by Ash don't actually support the article contents. I have looked hard for discussion of the topic rather than just uses of the term and mostly I've come up blank. The Virginia Ironside quote and some of the law journal info is the closest I've found to discussion of the concept, but it's in passing and pretty flimsy material for basing an article on.

Secularity and Secularism are distinct concepts

Wolfkeeper, you redirected Secularity to Secularism, however these are two distinct concepts and have seperate entries for that reason. The rationale you stated in your edit summary is not correct as "secularity" is a noun. "Secular" is the adjective form, as the entry clearly states. If you believe "secularity" is only appropriate for a Wictionary entry, then the correct avenue is AfD since secularlity and secularism are, once again, not synonymous. Please discuss this matter here or on the entry talk page instead of simply reverting without as much as an edit summary. Please take note of WP:BRD as well. Thanks.
