Frequently Asked Questions about Physics


Will there be downloadable PDF files of Physics articles?

PDFs for Physics articles are now available (October 14, 2008)!


How may I stay up-to-date with Physics?

There are two ways to be alerted about new content in Physics. First, we provide an RSS feed that is an ideal way to keep up with new content. This feed is available at http://feeds.aps.org/rss/recent/physics.xml (or by clicking on the RSS icon in the banner of each page of the Physics web site). For more APS RSS feeds as well as information about how to use RSS feeds, please see http://feeds.aps.org/. We also offer email alerts that are typically sent out once a week. You may sign up to receive these alerts at http://physics.aps.org/email_alerts.


Is Physics online-only?

Yes. However, we may periodically make print versions (collections of articles) in a magazine style.


Will Physics be offered by subscription, or will it be open access?

Physics is, for the foreseeable future, open access, as are the underlying papers that are highlighted by Viewpoints, but not those articles cited in the Synopses or Trends articles. To get to the free-to-read articles, you need to enter through the Physics site, rather than the APS journal home pages.


What is the relationship between Physics and Physical Review Letters and the other Physical Review journals?

Unlike Physical Review Letters and the other Physical Review journals, Physics does not publish primary research. Its purpose is to highlight the best papers in the Physical Review journals. The editors of the journals participate in selecting which papers will be highlighted.


Will Physics cover articles from other journals?

While we are currently focusing on the Physical Review journals for our source articles, we do hope to expand our coverage in the future.


What is the difference between Physics and Physical Review Focus?

Physics features commentaries written by working scientists on papers in the Physical Review journals. These articles are intended for a readership of physicists and researchers in related fields, at the level of advanced undergraduates or above. Focus offers summaries in a journalistic style written by professional science writers, for readers at a very broad level including interested laypersons.


What are the subject categories and will new ones be added?

We revise the subject categories over time. Some are based on those in our research journals (see the various subject-based RSS feeds at http://feeds.aps.org/ for example), but some aren't. A list of the current categories can be seen on the Archives page (http://physics.aps.org/browse).


Why aren't I seeing some mathematical symbols properly (showing up as boxes)?

Physics uses Unicode (UTF-8) to represent mathematical symbols and other special characters. Unicode is an international standard for encoding characters. In order to properly display articles in Physics, fonts covering Unicode mathematical symbols must be installed on your system. Most modern operating systems (including Mac OS X, Unix/Linux, and Microsoft Windows Vista) have a reasonably complete set of Unicode fonts installed. Slightly older operating systems, or those without all of the fonts/additional packages installed, may require additional fonts to be installed. In particular Windows XP does not ship with a complete set of fonts. If you have installed Microsoft Office 2007 you already have the 'Cambria' font installed which is complete. If you are seeing boxes or other strange characters when viewing one of our articles please install one of the freely available fonts below.
