about Wilson-Sommerfeld's Quatization

[edit]

NOTA:For I'm convinient to read at short time,do the following articles for myself.

I've read Modern Physics about Wilson-Sommerfeld's Quatumzation Theory. I don't understand:

1.Why did they consider that ?
Because it is the action (physics)
2.By 1.,I think that was just correct with some limit of
Uncertainty Principle if P represents(ed) "Poition". I said
right? Or it obeyed U.P.?
No, P is the momentum.
Thanks for correction. Previously I wanted to show was that P stands for "Period",not for "Positon". Actually I know it stands for momentum.--HydrogenSu 11:34, 27 January 2006 (UTC)[reply]
3.Why does ? Then we by this to solve A
(amplitude)? And however,by what theory? See please
File:Modern physics.jpg
That snapshot of the whiteboard shows that P is the momentum. You may also choose to think of the action as if it were the total angular momentum; the Bohr-Sommerfeld quantization condition states that the total angular momentum is quantized. The theory is thier own: they invented it in order to try to explain atomic spectra. linas 22:00, 26 January 2006 (UTC)[reply]

Hi SU:

The use of the action variable was useful in classical physics long before Wilson (1915) and Sommerfeld (1916) used it to extend Bohr's theory of the hydrogen atom.

Some terms the integral of p with respect to q is called the phase integral and its value, usually denoted by J, is called the action variable. The integral is taken over one period. (q is a generalized coordinate and p is the conjugate momentum.)

So the question, of course, is what does it mean. The best way to see this is to form the partial derivative of J with respect to E the energy. This produces the period.

When you have something moving in a plane it will be described by two vasriables. These two may be periodic. If the periods are commensurate the path of the object will be closed and periodic. If the individual periods are not commensurate the path need not close. An example is a Lissajous figure. The action variable is used to derive frequency information for the system.

I hope this breif reply helps.

**Modern Physics: Radiation of Blackbody

[edit]

Q:Please derive all of Rayleigh-Jeans’s Black Body Radiation Theory. And tell out why they failed.

My solution is as the followings:

In a cavity,there exists some EM-waves to travel all-in it.

  • (1)EM-waves' frequency ,
With
which gives that the more frequency(as),the more State-Numbers(as N). In the formula, is as Volume.
Considering one dimensional standing-wave
It can be set be a shell's radius.
Because EM-waves have 2 modes,
Where is a state-number which keeps a constant :
And can have different combinations to each other.( is for a shell volume of whole-circle speed.)
By , gives
  • (2)With "Energy continued distrubution of S.H.O." and with Boltzmann speed distribution, so energy released by a vibrating frequency on atoms
By the difinition of energy density:
Total energy is that average energy multiplies state-numbers
  • (3)In a cavity, the energy density of
With. Which we can ignore both sides of it.


Obviously, as then the energy becomes ,any blackbody are broken, it is impossible! (Tragedy of UV-light) So their theory was wrong when higher frequencies.--HydrogenSu 17:07, 4 February 2006 (UTC)[reply]

Can anyone talk about your thoughts? Thanks.

By their math expression we can clearly find angular frequency of which keeps constant when a wave vibrates up and down localized. That may because of energy transports into a wave is conservative,just like a particel moves up and down in a Y axis,localizedly(which keeps energy conservative).
But for another one,it travels in an X axis,that hints its phase-angular is the function of time. By time changes,then naturely changes either.

I'm a little not sure above. Could anyone discuss with me? For the reason of I rarely coming here,so email me: as any new reply about this question appears.

Laplace transform calculation (暫存文件)

[edit]

I have a question on[19] Anyone please help me.

(On which,why do for-all ,therefore they all equal to 0?)

--HydrogenSu 12:16, 4 February 2006 (UTC)[reply]

your question seems to be unclear. I think perhaps you want to ask why

equals 0. I think the explanation is supposed to go like this: a function f is odd if for all x, f(x)=f(–x). Odd functions satisfy

since the positive area on one side of the y-axis cancels out with the negative area on the other side. With some care, this result can be extended to improper integrals. For even functions, you can't cancel out the area, but you can say that the total area from –∞ to +∞ is twice the area from 0 to +∞. This is used in the subsequent step, and accounts for the 2 in front of the cosine.

The sine function is indeed an odd function, and the cosine function is indeed even. However, the integrand above is not the sine function, but rather the product of a sine and an exponential. As far as I can see, the integrand is not odd, and therefore this step of the calculation is an error. Nor is the 2 in front of the cosine correct.

This calculation seems to be proceding with a Fourier transform, which isn't really appropriate for doing a Laplace transform.

What I would suggest instead would be to start with the identity

then square it, and integrate the resulting exponentials. -lethe talk + 13:10, 4 February 2006 (UTC)[reply]

After trying it myself, I think that the above suggestion isn't so great, and you'd be better served with the identity

Some thoughts

[edit]

Your past 200+ edits to Wikipedia are nearly exclusive to the reference desk, and when I look a bit further into your contributions, most of your contributions are for soliciting ideas, and do not seem to indicate that you have a desire to contribute much to the main article namespace. Of your 742 edits, only 34 are actually to articles - the rest of them are discussion posts.

Your recent contributions to the reference desk have flooded it with your questions - we all love helping out with questions, but I think you have to be a bit more mindful that there are others who use the reference desk - we are all sharing the same space, and sometimes we need to make room for others. This might mean posting questions in a more concise way, or following up by staying on topic - as opposed to introducing other irrelevant ideas and shouting other editors down.

I know some of BluePlatypus' comments came across as a bit harsh, which prompted you to respond in the way you did - sometimes, we just need to refrain from doing that, or relegating it to somewhere else. It isn't necessary to broadcast your dissatisfaction to everyone - when you do this, it is easily misinterpreted as attention seeking or even trolling behaviour - behaviours which do not reflect accurately of you, nor positively of you. I'm sure you would be a wonderful person to meet and talk to, but today I was a bit disappointed to see that the better side of you did not shine through as much.

Now, I think what happened today was that BluePlatypus was trying to encourage some insight for you by suggesting a different approach to calculate your integrals. Perhaps it was a bit offensive to you when he suggested that you needed to go back to the basics. Yes, perhaps it could have, and should have been worded differently. Even though it might have sounded harsh to you, I don't think BluePlatypus actually intended his/her comments to be deliberately malicious - so for this reason, may I ask that you set the issue aside and move on? There are better things to do, like conveying the elegance of the physics that is in those equations. The integrals are part of a rich family of related equations, and they are very well established in the literature. If you have time after your exams, it will be very worthwhile to look these up.

If you have other questions you want to post on the reference desk, please feel free to do so - but I also hope that you can integrate some of my suggestions here as well. It would make your experience on Wikipedia much more enjoyable, and it would also make all the volunteers who help you feel good knowing that they were able to assist you in your aspirations to become a physicst. I hope this helps, and if anything I hope it makes you feel better :-) --HappyCamper 18:51, 10 February 2006 (UTC)[reply]

Thanks for your thoughts. I'm tired and the same time see your messege then get in. Maybe I made a lot of mistakes. It's now dark-night in Taiwan. Something's out of my brain. I just now read about your posts above. Some English vocabulary I don't understand. But I guess what you expressed was that I posted too much a day and made some issues with others or I typed too much Chinese....?
I'm going to sleep....Sorry--HydrogenSu 19:07, 10 February 2006 (UTC)[reply]
Much better on reading English words. I'll move on the issue articles.--HydrogenSu 19:17, 10 February 2006 (UTC)[reply]
Yes, go to sleep :-)
Well, I typed all that because I'm not sure what was the best way to approach you, but you do seem to be a reasonable person. Well, what I had an issue with was just how you responded to everything. I felt that we stopped listening to each other when we started talking about politics and God. Those are important too, but it was also making it difficult to be approachable and to answer the questions which you were really interested in. I think everyone became a bit hurt and defensive - me included.
By the way, a significant number of editors on Wikipedia have PhDs in physics, so it is nice to see some questions from our earlier years show up once in a while. You do have quite a bit of enthusiasm for science and physics!
In short:
  1. Keep the questions on topic - we do like to help
  2. Be nice. Sometimes if we get a response that doesn't seem helpful, just wait - another person will come by and give a better one soon.
  3. Chinese is wonderful :-)
That is all. See you around! --HappyCamper 19:22, 10 February 2006 (UTC)[reply]
P.S. By the way, in English, it is very rare to see the word "vocabularies" - in fact, I have never seen it myself. This is because the word "vocabulary" is both singular and plural. Your sentence was right the first time around. :-) --HappyCamper 19:22, 10 February 2006 (UTC)[reply]

Misunderstanding

[edit]

I do apologize for criticizing your English and embarrassing you. I thought your first comment was inappropriate. I thought you meant something like "This problem is so easy, any Chinese junior high school student could do it." I probably misinterpreted you. But my next comment was even more inappropriate and I should not have made it, so I apologize. No hard feelings? —Keenan Pepper 22:57, 12 February 2006 (UTC)[reply]

BTW, "I'm sorry" can mean two different things, regret, or sympathy. Sympathy is when you feel bad for something that happened to someone else, but it's not your fault. Regret is when you feel bad for something you've done and wish you hadn't done it. Google says "sympathy" is 同情 and "regret" is 遗憾. Does those sound right to you? How do you pronounce them? —Keenan Pepper 23:03, 12 February 2006 (UTC)[reply]
It's ok. Much better. I also did wrong very much. I do apologize too to you. I'll delete some motioned words in that math question. I get tired and to sleep.--HydrogenSu 23:33, 12 February 2006 (UTC)[reply]

Adding comments

[edit]

Hey HydrogenSu. I noticed that sometimes when you comment, your new comment is on top of your old comment. This is sometimes very confusing for readers so could you try to remember to sign comments on the bottom?

It is too bad that there are not many Taiwanese (or Chinese) speakers on Wikipedia right now, because I'm sure they could help you with your questions much easier. Even though you say Chinese is very hard for westerners, I don't find it so difficult, and I can understand maybe 50% of what you say in Chinese (though the new characters you use for Taiwanese sometimes confuse me). Unfortunately I don't have a lot of knowledge about the questions that you ask, so I can't really help.

Anyways, please try to keep your questions neat, and they will be easier to read; easier to answer! If you have any questions about my English, please leave me a message on my talk page.  freshgavinΓΛĿЌ  15:57, 23 February 2006 (UTC)[reply]

Just a note about Chinese is very hard for westerners... Speaking and listening to Chinese is very hard. Reading and writing Chinese is not. In fact, it is easier than English. You don't have to memorize tons of past/present/future tenses for verbs, pronouns for he, she, and it, conjunctions for comparisons, contrasts, and unions... Chinese grammar is much easier than English and the Chinese characters are much more fun to write. --Kainaw (talk) 01:06, 24 February 2006 (UTC)[reply]

Warning sign
This media may be deleted.

Thanks for uploading Image:Modern physics001.jpg. I notice the 'image' page currently doesn't specify who created the content, so the copyright status is unclear. If you have not created this media yourself then there needs to be an argument why we have the right to use the media on Wikipedia (see copyright tagging below). If you have not created the media yourself then it needs to be specified where it was found, i.e., in most cases link to the website where it was taken from, and the terms of use for content from that page.

If the media also doesn't have a copyright tag then one should be added. If you created/took the picture, audio, or video then the {{GFDL-self}} tag can be used to release it under the GFDL. If you believe the media qualifies as fair use, consider reading fair use, and then use a tag such as {{Non-free fair use in|article name}} or one of the other tags listed at Wikipedia:Image copyright tags#Fair_use. See Wikipedia:Image copyright tags for the full list of copyright tags that you can use.

If you have uploaded other media, consider checking that you have specified their source and copyright tagged them, too. You can find a list of 'image' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "Image" from the dropdown box. Note that any unsourced and untagged images will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you. 82.83.96.38 12:33, 19 May 2006 (UTC)[reply]

[edit]

Thanks for uploading Image:Modern physics001.jpg. However, the image may soon be deleted unless we can determine the copyright holder and copyright status. The Wikimedia Foundation is very careful about the images included in Wikipedia because of copyright law (see Wikipedia's Copyright policy).

The copyright holder is usually the creator, the creator's employer, or the last person who was transferred ownership rights. Copyright information on images is signified using copyright templates. The three basic license types on Wikipedia are open content, public domain, and fair use. Find the appropriate template in Wikipedia:Image copyright tags and place it on the image page like this: {{TemplateName}}.
