One of JaxoDraw's main features is the possibility to create LaTeX source files to were plugins available for export to PDF and SVG format. hi to all, it would be fine to export in pdf, in this way diagrams are easily usable into beamer class, which uses pdflatex only thanks roberto. JaxoDraw's main features is the possibility to create LaTeX files which make use of J. The PDF version of the user guide is produced.

JaxoDraw is a Feynman graph plotting tool written in Java. of JaxoDraw's main features is the possibility to create LATEX files which make. Changes relative to axodraw4j distributed with JaxoDraw. . pdf). The original axodraw worked only with the latex-dvips processing chain. Jaxodraw LaTex export is not generating any figure after compilation . and then Dvi>PS it compiles successfully, but then when I try PS>PDF.

This might be a more effective way of adding any extra functionality you need. Let's use the most flexible setup for JaxoDraw. This involves downloading a tarball from the main Web site, in the Downloads section. The filename you should see is jaxodraw-x.

Once this file is downloaded, you can unpack it with the command: tar xvzf jaxodraw-x. To start up JaxoDraw, first change to the new subdirectory and run: java -jar jaxodraw-x.

On start up, you will have an empty canvas and a list of the elements available to draw your Feynman diagram Figure 1. The left-hand side is broken into several sections, including the types of particles or the types of edits available.

This way, you can load them again later to make edits or build up more-complicated reactions. Figure 1.

JaxoDraw on Startup To begin drawing, first select an object type from the left-hand side. The regular particle types are fermions straight lines , scalars dashed lines , ghost dotted lines , photons wiggly lines and gluons pig-tailed lines. In the diagrams, there are four versions of these particle lines: lines, arcs, loops and beziers. Once you select one of those, you can draw on the canvas by clicking and dragging to draw the relevant line. You can draw anywhere on the canvas, or you can force the drawing to snap to grid points.

The spacing of these grid points is adjustable in the Preferences. At least in the beginning, you probably will want to turn this on so that you can make the different sections of your drawing line up.

Each of the elements of your drawing has properties that can be edited. You need to select the edit tool from the left-hand side, and then select the element you want to edit Figure 2. Figure 2. Edit Options From here, you can edit the location, whether there is an arrow and which direction it points, the line width and arrow dimensions.

There is also a text element you can use to label your diagram.

This allows you to use special characters, such Greek letters, in your text label. Be sure to select the text type based on what you want to produce for exported output. You can group a number of diagram elements together in a single entity. You need to press the selection tool on the left-hand side and then click on each of the entities for the group you are creating.

This grouped entity then can be moved as a single object. You can group together these groups into super groups. There is no technical limit to this type of nesting. You can get a rough idea of what your Feynman diagram will look like, but things like LaTeX text aren't rendered on the drawing canvas.

You need to pass it through a rendering program and then view the output.


To get a preview of your finished diagram, be sure to set the preferred PostScript viewer, the LaTeX path and the dvips path. A common PostScript viewer is gv, the viewer that comes with ghostscript. This way, you always can go back and re-create the diagram if needed. You can export your Feynman diagram in one of several formats.

This style file is called axodraw4j.

Vermaseren's original axodraw. This is now a separate download from the main JaxoDraw application download. Limits of the project are that it -- other than LaTeX -- is not very fit for scientific use, since it does not support cross-references, indices or numbered figures. Also the amount of output formats is limited.

Mom is dedicated to produce PostScript and therefore also PDF , theoretically, "grotty" and "grohtml" also allow outputting raw text and HTML, but the project doesn't pay attention to these. Originally written by a Canadian writer for his own needs, Mom offers exactly what Peter Schaffter needed: an easy yet fully featured way of letting text look good.

In his eyes, Peter Schaffter is one of the unsung heroes of Free Software, and he was particularly impressed how friendly and quickly his suggestions automatic generation of a table of contents was picked up. By the way: if you also want to contact Peter Schaffter, you should make sure that your email contains the words "groff" or "mom" in the subject, otherwise it won't survive the spam filter. Even though a few more additions may be added to Mom upon request, Mom is considered stable and Peter Schaffter would like to leave it up to the other users to decide which expansions are useful or necessary.

Not only as a gift in return and to say thanks, but also because he feels close to the social values of Free Software.

Feynman Figures for Fun

Study about "Hacker Ethics" There are in fact an increasing amount of "classical" approaches trying to understand the phenomenon of Free Software.

In quite different faculties from economy to sociology diploma and PhD theses are conducted on this topic.

During that summer his interest for the philosophical background of the GNU Project [13] was raised -- specifically by the articles of Richard Stallman. Based upon the book by Stephen Levy "Hackers", he began serious studies on the phenomenon and also included constructive controversy with "The Hacker Ethic" by Pekka Himanen in his dissertation. The paper was turned in July 7th , so it is finished, but available as free documentation under the GNU Free Documentation License GFDL and if someone was willing to help with this, Aputsiaq would explicitly welcome a translation from Danish into English.

Since began working and will most likely move to Greenland in , he probably won't find the time himself. His favorite anecdote for the dissertation is that during his discussions with Richard Stallman, Richard voiced scepticism as to whether a hacker ethics exists as such.

The final word on issues of the knowledge and information society has certainly been spoken yet. Not unexpectedly, the quickly called-for PrepComIIIa didn't bring a solution for the critical issues such as human rights, financing, limited intellectual monopolies in particular Copyrights and Patents and Free Software.

In the area of Free Software, a compromise seemed imminent, but the USA made their acceptance of that paragraph dependant upon the acceptance of the limited intellectual monopoly paragraph by other countries. The group on this issue had several "open ended" meetings starting at and usually had to close without result around During these 3.

The German ministry of justice quickly flew in an expert on the issue for consultation and a consensus was sought in bilateral as well as multilateral discussions. This will most likely take the shape of highlighting the importance of a balance between monopolization and accessibility of knowledge without implying whether that balance exists or does not exist today. According to last information, the negotations are revolving around that point. The suggestion of Civil Society, which in fact did achieve this tricky point wasn't officially brought forward by any government as everyone feared bringing in new text might end up confusing the situation more.

Also potentially interesting in this context is the article "Fighting Intellectual Poverty -- Who owns and controls the information societies? Essential Benchmarks Civil Society, so the part of the summit that is neither government nor economy or organization close to the UN, increasingly focussed on getting their own vision forward.

This is the most compact and encompassing document so far -- and the Civil Society "Visionary Declaration," which is about to be written as a counter-vision to the governmental declaration, will also have to benchmark itself against these.

The Canvas

But even within Civil Society there is still substantial need for discussion and the lines of conflict permeate all areas. In internet governance there is still a discrepancy between the North, which seeks more independence from governmental control, and the South, for whom governmental control seems to provided the desired stability.

Questions of limited intellectual monopolies are also still in need of discussion; while some organizations seek to protect the rights of indigenous peoples by increased monopolization, this is in conflict to the largest part of the world, where a readjustment of monopolies is needed to allow access to information and help overcoming the digital divide.

Within Civil Society there are also many who for instance have not yet understood software as a new cultural technique and realized why Free Software provides answers to fundamental social questions.

Coin slots in hotel rooms? As a final word I'd like to say something about an absurdity that has seen massive spread recently, particularly in hotels and airports: wireless internet access at ridiculously high charges. Installing a simple wireless access point in the lobby of a hotel or the lounge of an airport within most Northern countries usually requires no more than an investment of up to EUR and monthly fees of about 30 EUR DSL flatrate.

In fact there are more and more hotels and airports offering wireless networks.

But usually these come at EUR per half-hour of internet access.Originally written by a Canadian writer for his own needs, Mom offers exactly what Peter Schaffter needed: an easy yet fully featured way of letting text look good. On button release, a menu will be presented with a choice of operations applicable to the current selection of enclosed objects.

Time increases from left to right. By default the line is a solid single line without an arrow. The current document only outlines the major changes with respect to the features described in the published User Guide [1] for JaxoDraw It contains up-to-date information about the program, in particular links to our mailing lists1 and bug-tracking system2.
