Plank's time

edit

I saw that you added the following section to the Plank's time article. I moved it to the disscussion page for since it seemed out of place and confusing. I could not see what value it added to the main article. Bshoemate 15:59, 7 October 2007 (UTC)Reply

Derivation

edit

Ignoring a factor of  , the Planck mass is roughly the mass of a black hole with a Schwarzschild radius equal to its Compton wavelength. The radius of such a black hole would be, roughly, the Planck length.

The following thought experiment illuminates this fact. The task is to measure an object's position by bouncing electromagnetic radiation, namely photons, off it. The shorter the wavelength of the photons, and hence the higher their energy, the more accurate the measurement. If the photons are sufficiently energetic to make possible a measurement more precise than a Planck length, their collision with the object would, in principle, create a minuscule black hole. This black hole would "swallow" the photon and thereby make it impossible to obtain a measurement. A simple calculation using dimensional analysis suggests that this problem arises if we attempt to measure an object's position with a precision greater than one Planck length.

This thought experiment draws on both general relativity and the Heisenberg uncertainty principle of quantum mechanics. Combined, these two theories imply that it is impossible to measure position to a precision greater than the Planck length, or duration to a precision greater than the time a photon moving at c would take to travel a Planck length. Hence in any theory of quantum gravity combining general relativity and quantum mechanics, traditional notions of space and time will break down at distances shorter than the Planck length or times shorter than the Planck time.

License tagging for Image:Electricjacobsladder.gif

edit

Thanks for uploading Image:Electricjacobsladder.gif. Wikipedia gets hundreds of images uploaded every day, and in order to verify that the images can be legally used on Wikipedia, the source and copyright status must be indicated. Images need to have an image tag applied to the image description page indicating the copyright status of the image. This uniform and easy-to-understand method of indicating the license status allows potential re-users of the images to know what they are allowed to do with the images.

For more information on using images, see the following pages:


This is an automated notice by OrphanBot. If you need help on selecting a tag to use, or in adding the tag to the image description, feel free to post a message at Wikipedia:Media copyright questions. 18:07, 23 June 2006 (UTC)

Image tagging for Image:Nudelta house.JPG

edit

Thanks for uploading Image:Nudelta house.JPG. The image has been identified as not specifying the source and creator of the image, which is required by Wikipedia's policy on images. If you don't indicate the source and creator of the image on the image's description page, it may be deleted some time in the next seven days. If you have uploaded other images, please verify that you have provided source information for them as well.

OphanBot, leave me alone. —The preceding unsigned comment was added by Tyco.skinner (talkcontribs) .

It's nothing personal. Wikipedia takes copyright pretty seriously. By policy, images must have their copyright status specified, or else they are deleted. There are several bots that scan newly uploaded images to check that a copyright status has been specified. --Srleffler 00:06, 1 August 2006 (UTC)Reply

Again, welcome!  --Srleffler 00:04, 1 August 2006 (UTC)Reply

It's weird to get a welcome, because I only recently made an account, but have been reading/editting for a while. ;D --HantaVirus 12:54, 18 August 2006 (UTC)Reply

Really hoping you will come back and contribute to the discussion on some of the issues you raised. This article recently had a lot of unbalanced editing and though it retained featured article status the emphasis has shifted too far away from the reality of AS. --Zeraeph 11:13, 1 August 2006 (UTC)Reply

Strait is on my side

"Lawl! Strait is on my side, wtf!? --HantaVirus 21:02, 4 August 2006 (UTC)"

Why is this surprising? Have we been at odds before? --Strait 03:09, 10 August 2006 (UTC)Reply

Oh, I said that because several my edits have recieved further editing by you, as of late. And that was the first instance in which you were in agreement with something that I had said. Haha, I meant no foul. --HantaVirus 13:50, 10 August 2006 (UTC)Reply


Proposed deletion of Graduation year

edit
 

The article Graduation year has been proposed for deletion because of the following concern:

Dictionary definition, which is unsuitable for Wikipedia.

While all contributions to Wikipedia are appreciated, content or articles may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the {{dated prod}} notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the article to address the issues raised. Removing {{dated prod}} will stop the Proposed Deletion process, but other deletion processes exist. The Speedy Deletion process can result in deletion without discussion, and Articles for Deletion allows discussion to reach consensus for deletion. Taelus (talk) 15:43, 27 August 2009 (UTC)Reply

File source problem with File:Nudelta house.JPG

edit
 

Thank you for uploading File:Nudelta house.JPG. I noticed that the file's description page currently doesn't specify who created the content, so the copyright status is unclear. If you did not create this file yourself, you will need to specify the owner of the copyright. If you obtained it from a website, please add a link to the website from which it was taken, together with a brief restatement of that website's terms of use of its content. However, if the copyright holder is a party unaffiliated from the website's publisher, that copyright should also be acknowledged.

If you have uploaded other files, consider verifying that you have specified sources for those files as well. You can find a list of files you have created in your upload log. Unsourced and untagged images may be deleted one week after they have been tagged per Wikipedia's criteria for speedy deletion, F4. If the image is copyrighted and non-free, the image will be deleted 48 hours after 10:18, 4 May 2010 (UTC) per speedy deletion criterion F7. If you have any questions or are in need of assistance please ask them at the Media copyright questions page. Thank you. Sfan00 IMG (talk) 10:18, 4 May 2010 (UTC)Reply

Nomination of ApNano for deletion

edit

A discussion has begun about whether the article ApNano, which you created or to which you contributed, should be deleted. While contributions are welcome, an article may be deleted if it is inconsistent with Wikipedia policies and guidelines for inclusion, explained in the deletion policy.

The article will be discussed at Wikipedia:Articles for deletion/ApNano until a consensus is reached, and you are welcome to contribute to the discussion.

You may edit the article during the discussion, including to address concerns raised in the discussion. However, do not remove the article-for-deletion template from the top of the article. -- Alan Liefting (talk) - 00:12, 27 September 2010 (UTC)Reply

ArbCom elections are now open!

edit

Hi,
You appear to be eligible to vote in the current Arbitration Committee election. The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to enact binding solutions for disputes between editors, primarily related to serious behavioural issues that the community has been unable to resolve. This includes the ability to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail. If you wish to participate, you are welcome to review the candidates' statements and submit your choices on the voting page.
