Are there resources for learning how to write a scientific paper? I have very little formal training, but I believe I have some ideas to share. I have surveyed the terrain of ideas I need and have the complete picture in some haphazard form in my head. It is seeming quite impossible for me to write anything that looks good, complete and coherent. In attempting to do this I have read my previous draft and it seems hopeless... I am not sure what I can do, at this point. I'm not in a hurry, I can spend a month on the text to get the technique right. More specifically:


Is there a text that trains you on how to write a mathematical physics paper?  
Is it possible to acquire such skills informally?
Some resources on writing mathematics, which I assume will be useful in mathematical physics, are:

Donald E. Knuth, Tracy L. Larrabee, and Paul M. Roberts, Mathematical Writing, (Washington, D.C.: Mathematical Association of America, 1989), ii+115pp. ISBN 0-88385-063-X. [You can download this (minus illustrations) from Knuth's website: http://www-cs-faculty.stanford.edu/~uno/klr.html ]

P.R. Halmos, "How to write mathematics". Enseignement Math. (2) 16 1970 123–152. [There are copies of this floating around online; I'm not linking because I'm not sure of their copyright status.]

However, in my own experience, guides like these are useful because they point out (1) a lot of things to avoid, and (2) a relatively small number of useful tips and tricks. Developing a good writing style is best accomplished by reading as much good writing as you can (including both scientific and other scholarly writing), writing as best you can, and seeking as much good feedback on your work as you can.

See also Jean-Pierre Serre's lecture "How to write mathematics badly", which is informative, funny, and (since his examples are taken from experience) tragic. Look out for the instance he highlights of "without" being abbreviated to "with."
