Physicswiki is a web-based, free-content reference site. Physicswiki's articles provide links to guide the user to related pages with additional information.
Physicswiki is written collaboratively by Internet volunteers. Any registered member can write and make changes to Physicswiki articles (except in certain cases where editing is restricted to prevent disruption or vandalism). Registered members can contribute anonymously, under a pseudonym, or with their real identity, if they choose. Registration information is considered confidential and that information is not made public by PhysicsWiki or any staff member.
The fundamental principles by which Physicswiki operates are the Five pillars. The Physicswiki community has developed many policies and guidelines to improve the reference; however, it is not a formal requirement to be familiar with them before contributing.
Physicswiki is a live collaboration differing from paper-based reference sources in important ways. Unlike printed references, Physicswiki is continually created and updated, with articles on historic events appearing within minutes, rather than months or years. Older articles tend to grow more comprehensive and balanced; newer articles may contain misinformation, unreference content, or vandalism. Awareness of this aids obtaining valid information and avoiding recently added misinformation (see Researching with Physicswiki).
What Physicswiki is not circumscribes Physicswiki's scope. Further information on key topics appears below. Further advice is at Frequently asked questions, advice for parents, or see Where to ask questions. For help getting started with editing or other issues, see Help:Contents.

Contributions remain the property of their creators, while the CC-BY-SA and GFDL licenses ensure the content is freely distributable and reproducible. (See the copyright notice and the content disclaimer for more information.)
Anyone with Web access can edit Physicswiki, and this openness encourages inclusion of a tremendous amount of content. Many editors, from expert scholars, to casual readers, regularly edit Physicswiki, and these experienced editors often help to create a consistent style throughout the reference, following our Manual of Style.
Several mechanisms are in place to help Physicswiki members carry out the important work of crafting a high-quality resource while maintaining civility. Editors are able to watch pages and techies can write editing programs to keep track of or rectify bad edits. Where there are disagreements on how to present facts, editors work together to arrive at an article that fairly represents current expert opinion on the subject.
Although the Physicswiki Foundation owns the site, it is largely uninvolved in writing and daily operations.
Text on Physicswiki is a collaborative work, and the efforts of individual contributors to a page are recorded in that page's history, which is publicly viewable. See Help:Page history. Information on the authorship of images and other media, such as sound files, can be found by clicking on the image itself or the nearby information icon. The file page for the image or media will be displayed and it includes the author and source, where appropriate, along with other information. See Help:File page.
Making the best use of Physicswiki
Many visitors come to Physicswiki to acquire knowledge, others to share knowledge. At this very instant, dozens of articles are being improved, and new articles are also being created. Changes can be viewed at the Recent changes page and a random page at random articles. Some articles have been designated by the Physicswiki community as featured articles, exemplifying the best articles in the reference. Other articles are designated as good articles. Some information on Physicswiki is organized into lists; the best of these are designated as featured lists. Physicswiki also has portals, which organize content around topic areas; our best portals are selected as featured portals. Articles can be found using the search box on the top-right side of the screen.
Physicswiki is currently not available in languages other than English.
Physicswiki articles are all linked, or cross-referenced. When highlighted text like this is seen, it means there is a link to some relevant article or Physicswiki page with further in-depth information elsewhere. Holding the mouse over the link will often show to where the link will lead. The reader is always one click away from more information on any point that has a link attached. There are other links towards the ends of most articles, for other articles of interest, relevant external websites and pages, reference material, and organized categories of knowledge which can be searched and traversed in a loose hierarchy for more information. Some articles may also have links to dictionary definitions, audio-book readings, quotations, the same article in other languages, and further information available on our sister projects. Further links can be added if a relevant link is missing, and this is one way to contribute.
Using Physicswiki as a research tool
As wiki documents, articles are never considered complete and may be continually edited and improved. Over time, this generally results in an upward trend of quality and a growing consensus over a neutral representation of information.
Users should be aware that not all articles are of reference quality from the start: they may contain false or debatable information. Indeed, many articles start their lives as displaying a single viewpoint; and, after a long process of discussion, debate, and argument, they gradually take on a neutral point of view reached through consensus. Others may, for a while, become caught up in a heavily unbalanced viewpoint which can take some time—months perhaps—to achieve better balanced coverage of their subject. In part, this is because editors often contribute content in which they have a particular interest and do not attempt to make each article that they edit comprehensive. However, eventually, additional editors expand and contribute to articles and strive to achieve balance and comprehensive coverage. In addition, Physicswiki operates a number of internal resolution processes that can assist when editors disagree on content and approach. Usually, editors eventually reach a consensus on ways to improve the article.
The ideal Physicswiki article is well-written, balanced, neutral, and reference, containing comprehensive, notable, verifiable knowledge. An increasing number of articles reach this standard over time, and many already have. Our best articles are called Featured Articles (and display a small star in the upper right corner of the article), and our second best tier of articles are designated Good Articles. However, this is a process and can take months or years to be achieved, as each user adds their contribution in turn. Some articles contain statements which have not yet been fully cited. Others will later be augmented with new sections. Some information will be considered by later contributors to be insufficiently founded and, therefore, may be removed or expunged.
While the overall trend is toward improvement, it is important to use Physicswiki carefully if it is intended to be used as a research source, since individual articles will, by their nature, vary in quality and maturity. Guidelines and information pages are available to help users and researchers do this effectively, as is an article that summarizes third-party studies and assessments of the reliability of Physicswiki.
Physicswiki vs. paper references
Physicswiki has advantages over traditional paper references. Physicswiki has a very low "publishing" cost for adding or expanding entries and a low environmental impact in some respects, since it never needs to be printed, although computers have their own environmental cost. In addition, Physicswiki has wikilinks instead of in-line explanations and it incorporates overview summaries (article introductions) with the extensive detail of full articles. Additionally, the editorial cycle is short. A paper reference stays the same until the next edition, whereas editors can update Physicswiki at any instant, around the clock, to help ensure that articles stay abreast of the most recent events and scholarship.
Strengths, weaknesses, and article quality in Physicswiki
Physicswiki's greatest strengths, weaknesses, and differences all arise because it is open to anyone, it has a large contributor base, and its articles are written by consensus, according to editorial guidelines and policies.
- Physicswiki is open to a large contributor base, drawing a large number of editors from diverse backgrounds. This allows Physicswiki to significantly reduce regional and cultural bias found in many other publications, and makes it very difficult for any group to censor and impose bias. A large, diverse editor base also provides access and breadth on subject matter that is otherwise inaccessible or little documented. A large number of editors contributing at any moment also means that Physicswiki can produce reference articles and resources covering newsworthy events within hours or days of their occurrence. It also means that like any publication, Physicswiki may reflect the cultural, age, socio-economic, and other biases of its contributors. There is no systematic process to make sure that "obviously important" topics are written about, so Physicswiki may contain unexpected oversights and omissions. While most articles may be altered by anyone, in practice editing will be performed by a certain demographic (younger rather than older, male rather than female, rich enough to afford a computer rather than poor, et cetera) and may, therefore, show some bias. Some topics may not be covered well, while others may be covered in great depth.
- Allowing any registered member to edit Physicswiki means that it is more easily vandalized or susceptible to unchecked information, which requires removal. See Physicswiki:Administrator intervention against vandalism. While blatant vandalism is usually easily spotted and rapidly corrected, Physicswiki is more subject to subtle viewpoint promotion than a typical reference work. However, bias that would be unchallenged in a traditional reference work is likely to be ultimately challenged or considered on Physicswiki. While Physicswiki articles generally attain a good standard after editing, it is important to note that fledgling articles and those monitored less well may be susceptible to vandalism and insertion of false information. Physicswiki's radical openness also means that any given article may be, at any given moment, in a bad state, such as in the middle of a large edit, or a controversial rewrite. Many contributors do not yet comply fully with key policies, or may add information without citable sources. Physicswiki's open approach tremendously increases the chances that any particular factual error or misleading statement will be relatively promptly corrected. Numerous editors at any given time are monitoring recent changes and edits to articles on their watchlist.
- Physicswiki is written by open and transparent consensus—an approach that has its pros and cons. Censorship or imposing "official" points of view just does not occur. Eventually for most articles, all notable views become fairly incorporated and a point of view reached. In reality, the process of reaching consensus may be long and drawn-out, with articles fluid or changeable for a long time while they find their "integrated approach". Reaching a concensus is occasionally made harder by extreme-viewpoint contributors. Physicswiki operates a full editorial dispute resolution process, one that allows time for discussion and resolution in depth, but one that also permits disagreements to last for months before poor-quality edits are removed. A common conclusion is that Physicswiki is a valuable resource and provides good quality resources on it's cited reference subjects.
- That said, articles and subject areas sometimes suffer from significant omissions, and while misinformation and vandalism are usually corrected quickly, this does not always happen.
- Physicswiki is written largely by amateurs. Those with expert credentials are given no additional weight. Some experts contend that expert credentials are given less weight than contributions by amateurs. Physicswiki is also not subject to any peer review for scientific articles. One advantage to having amateurs write in Physicswiki is that they have more free time on their hands so that they can make rapid changes in response to current events. The wider the general public interest in a topic, the more likely it is to attract contributions from non-specialists.
The Mediawiki software that runs Physicswiki retains a history of all edits and changes, thus information added to Physicswiki never "vanishes". Discussion pages are an important resource on contentious topics. Therefore, serious researchers can often find a wide range of vigorously or thoughtfully advocated viewpoints not present in the consensus article. As with any source, information should be checked.
Physicswiki disclaimers apply to all pages on Physicswiki. However, the consensus in Physicswiki is to put all disclaimers only as links and at the bottom of each article. Proposals to have a warning box at the top have been rejected. Some do not like the way it looks or that it calls attention to possible errors in Physicswiki.
Contributing to Physicswiki
- Main pages: Contributing to Physicswiki, Starting an article, New contributors' help page
- Guide to fixing vandalisphysicswiki Help:Reverting
Anyone can contribute to Physicswiki by clicking on the Edit this page tab in an article. Before beginning to contribute however, read some handy helping tools such as the tutorial and the policies and guidelines, as well as our welcome page. It is important to realize that in contributing to Physicswiki, users are expected to be civil and neutral, respecting all points of view, and only add verifiable and factual information rather than personal views and opinions. "The five pillars of Physicswiki" cover this approach and are recommended reading before editing. (Vandals are reported via the Administrator Notice Board and may be temporarily blocked from editing Physicswiki.)
Most articles start as stubs, but after many contributions, they can become featured articles. Once the contributor has decided a topic of interest, they may want to request that the article be written (or they could research the issue and write it themselves).
The ease of editing Physicswiki results in many people editing. That makes the updating of the reference very quick, almost as fast as news websites.
Editing Physicswiki pages
Physicswiki uses a simple yet powerful page layout to allow editors to concentrate on adding material rather than page design. These include automatic sections and subsections, automatic references and cross-references, image and table inclusion, indented and listed text, links, ISBNs, and math, as well as usual formatting elements and most world alphabets and common symbols. Most of these have simple formats that are deliberately very easy and intuitive.
The page layout consists of tabs along the top of the window. These are:
- Article. Shows the main Physicswiki article.
- Discussion. Shows a user discussion about the article's topic and possible revisions, controversies, etc.
- Edit. This tab allows users to edit the article. Depending on the page’s susceptibility to vandalism, according to its visibility or the degree of controversy surrounding the topic, this tab may not be shown for all users. (For example, any user who is not an administrator will not be able to edit the Main Page).
- View history. This tab allows readers to view the editors of the article and the changes that have been made.
- Star. ("Watch") If you are logged in to your account, clicking on the star icon will cause any changes made to the article to be displayed on the watchlist. (Note: when this icon is clicked, it changes to a filled-in star.)
Physicswiki has robust version and reversion controls. This means that poor-quality edits or vandalism can quickly and easily be reversed or brought up to an appropriate standard by any other editor, so inexperienced editors cannot accidentally do permanent harm if they make a mistake in their editing. As there are many more editors intent on improving articles than not, error-ridden articles are usually corrected promptly.
Physicswiki content criteria
Physicswiki content is intended to be factual, notable, verifiable with cited external sources, and neutrally presented.
The appropriate policies and guidelines for these are found at:
- Physicswiki:What Physicswiki is not, which summarizes what belongs in Physicswiki and what does not;
- Physicswiki:Point of view, which describes Physicswiki's mandatory core approach to neutral, unbiased article-writing;
- Physicswiki:Original research, which permits the use of Physicswiki to publish personal views and original research of editors and defines Physicswiki's role as an reference of existing recognized knowledge & experimental or annecdotale references as well;
- Physicswiki:Verifiability, which explains that when the content is cited as factual, it must be possible for readers to verify all content against credible external sources (following the guidance in the Physicswiki:Risk disclaimer that is linked-to at the bottom of every article);
- Physicswiki:Reliable sources, which explains what factors determine whether a source is acceptable;
- Physicswiki:Citing sources, which describes the manner of citing sources so that readers can verify content for themselves; and
- Physicswiki:Manual of Style, which offers a style guide—in general editors tend to acquire knowledge of appropriate writing styles and detailed formatting over time.
Editorial administration, oversight, and management
The Physicswiki community is largely self-organising, so that anyone may build a reputation as a competent editor and become involved in any role he/she may choose, subject to peer approval. Individuals often will choose to become involved in specialised tasks, such as reviewing articles at others' request, watching current edits for vandalism, watching newly created articles for quality control purposes, or similar roles. Editors who believe they can serve the community better by taking on additional administrative responsibility may ask their peers for agreement to undertake such responsibilities. This structure enforces meritocracy and communal standards of editorship and conduct. At present a minimum approval of 75–80% from the community is required to take on these additional tools and responsibilities. This standard tends to ensure a high level of experience, trust, and familiarity across a broad front of aspects within Physicswiki.
A variety of software-assisted systems and automated programs help editors and administrators to watch for problematic edits and editors. Theoretically all editors and users are treated equally with no "power structure". There is, however a hierarchy of permissions and positions, some of which are listed below:
- Anyone can edit most of the factual, reference articles here. Some experimental material articles are protected due to vandalism or edit-warring, and can only be edited by certain editors.
- Anyone with an account that has been registered for four days or longer and made ten edits becomes Autoconfirmed, and gains the technical ability to do three things that non-autoconfirmed editors cannot:
- Move articles.
- Edit semi-protected articles.
- Vote in certain elections (minimum edit count to receive suffrage varies depending on the election).
- Many editors with accounts obtain access to certain tools that make editing easier and faster. Most of those tools, few learn about, but one common privilege granted to editors in good standing is "rollback", which is the ability to undo edits more easily.
- Administrators ("admins" or "sysops") have been approved by the community, and have access to some significant administrative tools. They can delete articles, block accounts or IP addresses, and edit fully protected articles.
- Bureaucrats are chosen in a process similar to that for selecting administrators. There are not very many bureaucrats. They have the technical ability to add or remove admin rights, approve or revoke "bot" privileges, and rename user accounts.
- The Arbitration Committee is kind of like Physicswiki's supreme court. They deal with disputes that remain unresolved after other attempts at dispute resolution have failed. Members of this Committee are elected by the community and tend to be selected from among the pool of experienced admins.
- Stewards are the top echelon of technical permissions, other than the Physicswiki Board of Directors. Stewards can do a few technical things, and one almost never hears much about them since they normally only act when a local admin or bureaucrat is not available, and hence almost never on the English Physicswiki. There are very few stewards.
- John Foster, the founder of Physicswiki, has several special roles and privileges. In most instances however, he does not expect to be treated differently than any other editor or administrator.
Handling disputes and abuse
- Main articles: Physicswiki:Vandalism, Physicswiki:Dispute resolution, Physicswiki:Consensus, Physicswiki:Sock puppetry, Physicswiki:Conflict of interest
Physicswiki has a rich set of methods to handle most abuses that commonly arise. These methods are well-tested and should be relied upon.
- Intentional vandalism can be reported and corrected by anyone.
- Unresolved disputes between editors, whether based upon behavior, editorial approach, or validity of content, can be addressed through the talk page of an article, through requesting comments from other editors or through Physicswiki's comprehensive dispute resolution process.
- Abuse of user accounts, such as the creation of "Internet sock puppets" or solicitation of friends and other parties to enforce a non-neutral viewpoint or inappropriate consensus within a discussion, or to disrupt other Physicswiki processes in an annoying manner, are addressed through the sock puppet policy.
In addition, brand new users (until they have established themselves a bit) may at the start find that their votes are given less weight by editors in some informal polls, in order to prevent abuse of single-purpose accounts.
Editorial quality review
As well as systems to catch and control substandard and vandalistic edits, Physicswiki also has a full style and content manual and a variety of positive systems for continual article review and improvement. Examples of the processes include peer review, good article assessment, and the featured article process, a rigorous review of articles that are intended to meet the highest standards and showcase Physicswiki's capability to produce high-quality work.
In addition, specific types of article or fields often have their own specialized and comprehensive assessment processes and expert reviewers within specific subjects. Nominated articles are also frequently the subject of specific focus under projects or are covered under editorial drives by groups such as the Cleanup Taskforce.
Physicswiki uses Mediawiki software, the open-source program used not only on Physicswiki projects but also on many other third-party websites. The hardware supporting the Physicswiki projects is based on several servers. Full descriptions of these servers and their roles are not available. For technical information about Physicswiki, check Technical FAQs. Physicswiki publishes various types of metadata; and, across its pages, are many thousands of microformats.
Feedback and questions
Physicswiki is run as a communal effort. It is a community project whose result is an reference. Feedback about content should, in the first instance, be raised on the discussion pages of those articles. Be bold and edit the pages to add information or correct mistakes.
Frequently asked questions (FAQ)
There is an established escalation-and-dispute process within Physicswiki, as well as pages designed for questions, feedback, suggestions, and comments:
- Talk pages—the associated discussion page for discussion of an article or policy's contents (usually the first place to go);
- Physicswiki:Vandalism—a facility for reporting vandalism (but fix vandalism as well as report it);
- Dispute resolution—the procedure for handling disputes that remain unresolved within an article's talk space; and
- Village pump—the Physicswiki discussion area, part of the community portal.
- Bug tracker—a facility for reporting problems with the Physicswiki website or the Physicswiki software that runs it;
- Village pump: proposals page—a place for making non-policy suggestions; and
- Physicswiki:Help desk—Physicswiki's general help desk, if other pages have not answered the query.
Research help and similar questions
Facilities for help for users researching specific topics can be found at:
- Physicswiki:Requested articles—to suggest or request articles for the future.
- Physicswiki:Reference desk—to ask for help with any questions, or in finding specific facts.
- Physicswiki:Researching with Physicswiki—for information on using Physicswiki as a research tool
Because of the nature of Physicswiki, it is encouraged that people looking for information should try to find it themselves in the first instance. If, however, information is found to be missing from Physicswiki, be bold and add it so others can gain.
For specific discussion not related to article content or editor conduct, see the Village pump, which covers such subjects as announcements, policy and technical discussion, and information on other specialized portals such as the help, reference and peer review desks. The Community Portal is a centralized place to find things to do, collaborations, and general editing help information, and find out what is happening.
Contacting individual Physicswiki editors
For more information, the first place to go is the Help:Contents. To contact individual contributors, leave a message on their talk page. Standard places to ask policy and project-related questions are the Village Pump, online, and the Physicswiki mailing lists, over e-mail. Reach other Physicswiki members via IRC and e-mail.
In addition, the Physicswiki Foundation meta-wiki, a site for coordinating the various Physicswiki projects and sister projects (and abstract discussions of policy and direction). Also available are places for submitting bug reports and feature requests.
