WHY ARE WE WRITING PAPERS? J. F. Presentation of Scientific Results

To communicate our original, interesting, and useful research To let others know what we are working on (and that we are working at all) To organize our thoughts To formulate our research in a comprehensible way To secure further funding To further our careers To make our publication lists look more impressive To have fun? Because we believe someone is going to read it!!! J. F. Presentation of Scientific Results

STRUCTURE OF A PHYSICS ARTICLE J. F. Presentation of Scientific Results

Short letters PRL, APL, rapid communications, … 1-4 pages Title Abstract Homogeneous body includes introduction and acknowledgments 0-4 figures At most paragraph titles J. F. Presentation of Scientific Results

Regular articles 4-500 pages Title Abstract Introduction Body sections Conclusions/Summary Acknowledgments References Appendices J. F. Presentation of Scientific Results

Title informative, catchy, concise Semicolons? Why not, if it helps, though some consider them bad taste. J. F. Presentation of Scientific Results

Abstract concise, direct, informative Passive or active voice? I prefer passive, though in longer abstracts an occasional active assertion may be enlivening. Abstracts are now more important than ever due to the increasing large number of articles. One cannot read all the papers in each issue of PRL, not even in ones own field. Abstracts should state major findings, even some specifics (numbers, formulas showing basic trends). J. F. Presentation of Scientific Results

examples J. F. Presentation of Scientific Results

Introduction Give the first impression about the paper Place the work into broader context Relate to other relevant research Say why is the work important, in plain language State major achievements/limitations State techniques/methods Describe organization of the paper J.

writing equations To place equations in line write $s_x=a+b$. Symbol \$ separates the math format. This is how single equations are written between lines: \begin{equation} \delta s=\int_0^1 \gamma_{2,be}\cosh(w_b/L_{nb})s_{0b}\exp(qV_{be}/k_BT)dq. \end{equation} This is how multiple equations are written: \begin{eqnarray} \label{eq:2} a&=&\sum_{i=1}^{\infty}, \\ b&=&\log(x). \end{eqnarray} J.

HINTS FOR EFFECTIVE WRITING something about style J. F. Presentation of Scientific Results

disclaimer I am not a native English speaker and I am not a creative-writing professional. Everything that follows should be taken as my best attempt to teach my students intricacies and idiosyncrasies of physics writing, based on my own experiences and on reading inspiring literature. I claim no responsibility to the damage inflicted on students by following my advice too closely and producing unintelligible and grammar offensive research articles. Beware of my grammar hints. I am especially offensive to the articles (“the”, “a”, “an”, and the worst of all, none, “…”). I feel absolved by being a Slavic language (read: article-free) native speaker. J. F. Presentation of Scientific Results

Hint 1 Pick a published paper you like and try to emulate its structure and style Learn from eminent physics writers Some of my favorite physics writings are: •S. Weinberg: Relativity and Cosmology •Feynman, Leighton, Sands: Feynman Lectures in Physics •Landau and Lifschitz: Course in Theoretical Physics (*) (*)Iwould not recommend emulating the style of L&L in research papers, unless you can emulate their physics. J. F. Presentation of Scientific Results

Hint 2 Understand what you write, be clear Distance yourself from the writing to see it unbiased Logic must flow Ask a colleague if in doubt that writing may be incomprehensible useful point: Do not write “The energy increases with pressure”, but “The energy increases with increasing pressure”, to be clear, since one can often mean the opposite (“At low fields the rate decreases” can mean that the rate increases with decreasing fields, but one never knows.) J. F. Presentation of Scientific Results

Hint 3 structuring into ideas = structuring into paragraphs Place clue sentences in the beginning Read the paragraph and rewrite it if the logic does not flow J. F. Presentation of Scientific Results

Hint 4 Write in active voice I show that the process occurs These results show that ... (NO: It is shown by these results that ...) Be concise, precise, and direct Stay focused J. F. Presentation of Scientific Results

Hint 5 Be consistent If there is an allowed ambiguity, stick to your choice throughout the paper: For example: “We take five configurations for the macrostate. Each microstate is defined by …” Either pick microstate or configuration, some may get confused. Similarly with grammar. For example, if you describe an experiment in the past sense, do not switch randomly to the present one. J. F. Presentation of Scientific Results

Hint 6 No offense Avoid if possible words like Clearly Obviously As is well known Of course J. F. Presentation of Scientific Results

Hint 7 Read the guidelines Early in your professional life read the guidelines for authors to the journal you write for. Adhere to the most relevant points in future writings. J. F. Presentation of Scientific Results

Hint 8 Do not overdo Footnotes In-line equations References Figures Latin phrases Acronyms J. F. Presentation of Scientific Results

Hint 9 referring Include only equations, figures, tables, and references that you refer to Carefully define every term in equations Define all the lines and symbols in figures Each figure and table comes with a caption Number all equations All nontrivial statements should be explained or referenced J. F. Presentation of Scientific Results

Hint 10 Revise 5-10 times Spell check Grammar check Check for flow Shorten Give the paper to a colleague for opinion Stop revising after a revision eliminates a previous revision, or if you are revising 10th time. There is little chance you will improve anything. J. F. Presentation of Scientific Results

Final hint Do not put too much emphasis on writing. It is a tool to communicate your research, no less and no more. An average paper is cited perhaps 4 times, and read perhaps 7 (4 plus 2 referees plus 1 random reader) times. You need to balance your time. I know of terribly written articles that are cited 500 and more times. In the end, it is the idea that you present, and not the form of the presentation, that will be remembered. J. F. Presentation of Scientific Results

Single authors: I or we? I prefer I when addressing work done by myself: I show that … Using we is more formal and authoritative; it diffuses responsibility There can still be we, if inviting the reader to join the discussion: If we substitute A for B or If one substitutes A for B J. F. Presentation of Scientific Results

Hints for effective writing à la Barbara Goss Levi (*) (*) http://www.research.att.com/kbl/APS/dec97/rules.html J. F. Presentation of Scientific Results

1. Practice writing short summaries of longer articles (get the message out) 2. Combine writing with inspiring reading (emulate the style of your favorite writing) 3. Get rid of superfluous words (there is …, the fact that ...) J. F. Presentation of Scientific Results

4. Rewrite if it is not clear 5. Define your terms 6. Good writing is clear thinking J. F. Presentation of Scientific Results

SUBMIT & FIGHT J. F. Presentation of Scientific Results

Submission letter Dear Editor, We submit a manuscript entitled „Falling cats with jelly on the back: stable equilibrium versus instinct“, by E. Schroedinger and A. Einstein, for publication in Physical Review Letters. The manuscript considers the important problem of cats with a jelly spread on their back. The cats are left to fall free from a height of at least 50 cm, and observed in their fall. We have discovered that cats do not fall. Instead, they hover indefinitely. Our conclusions have far reaching consequences for both physics and biology. We are now pondering about what happens to the cats when they are entangled. The importance of our work as well as far reaching consequences of our discovery justify our manuscript to be considered for publication in Physical Review Letters. Below we suggest physicists who should be qualified to referee our work. Sincerely, E. Shroedinger A. Einstein Suggested referees: N. Bohr (Copenhagen), L. Boltzmann (Graz), L. Landau (Charkov) J. F. Presentation of Scientific Results

Referee reports Re: Falling cats with jelly ... By: E. Schroedinger and A. Einstein Dear Dr. Schroedinger: The above manuscript has been reviewed by our referee(s). On the basis of the enclosed critique, we judge that the work does not meet the special criteria of importance and broad interest required for Physical Review Letters. We also wish to emphasize that we take strong stance on the animal rights issue and we do not endorse experimenting with live animals, with our without jelly on their backs. Yours sincerely, E. Rutherford Senior Editor encl. Referee reports J. F. Presentation of Scientific Results

Referee A This paper presents an experimental treatment of combined effects of mechanical rotation and animal instincts. The treatment is sound, but cruel. I question the conclusions of the manuscript on the basis that the authors used only 1 cat which must have felt depressed about being thrown repeatedly from the Physics Department windows. As is known from the work of C. Darwin, depressed cats tend to hover in the air. The authors have failed to separate the effects of depression from those of mechanical rotation and biological instincts. Therefore I do not recommend the paper for publication in Physical Review Letters in the present form, although the subject itself is of great importance. J. F. Presentation of Scientific Results

Referee B The group of E. Schroedinger publishes reliable and interesting results (though I have some doubts about Dr. Einstein who tends to be off at times). The paper is well written, the results clearly stated. The subject is definitely of broad interest, as I have myself pondered about such things. The only question I have is whether the work is suitable for Physical Review Letters, or should be published in the „American Journal of Falling Cats“? I opt for the latter. J. F. Presentation of Scientific Results

Resubmission letter Dear Editor, We resubmit our mansucript entitled „Falling cats with jelly on the back: stable equilbrium versus instinct“, by E: Schroedinger and A. Einstein, for publication in Physical Review Letters. We consider the criticism of the referees well meant, and in fact supporting publication in your journal. Referee A says „The treatment is sound...“ and „...is of great importance.“ Referee B claims that the paper is well written and of broad interest. We address the few minor critical points in the enclosed response to the referees. Since we have addressed ALL the referee comments, and since the comments themselves can be interpreted as positive, we strongly request that you publish our manuscript without further delay. Sincerely, E. Shroedinger A. Einstein J. F. Presentation of Scientific Results

Response to the referees Response to referee A: We thank the referee for his or her thoughtful comments and for carefully reading our manuscript. We were not aware of the important research of C. Darwin on falling depressed cats. Taking into consideration that our cat could have indeed been depressed by both falling down so often and having jelly on the back, and so not wanting to really fall down, we have put the cat on an antidepressant (Whiskas Prozac) and let it fall several times again. We are happy to report that our original results stay unchanged. Unfortunately, the poor cat has died. Probably from an overdose of Prozac. Response to referee B: We appreciate the referee‘s well thought comments and for suggesting an alternative journal for our manuscript. We have looked at several recent issues of AJFC to see if indeed this would be the appropriate place for our cat. Unfortunately, AJFC seems to publish only very technical papers on the subject, with little emphasis on the physics involved. We strongly believe that PRL is the most suitable journal for publishing our work. J. F. Presentation of Scientific Results

Acceptance (rejection) letter Re: Falling cats with jelly ... By: E. Schroedinger and A. Einstein Dear Dr. Schroedinger: We are pleased to inform you that the above manuscript has been accepted for publication. You are requested to make a payment of $1000 toward the cost of disseminating your research results. Yours sincerely, E. Rutherford Senior Editor J. F. Presentation of Scientific Results
