How to write publishable-quality math and science papers? I've learned it a bit, through a thesis paper (not PhD-level), and from reading good papers in good journals.  But I'm interested in best practices, specifically the things to implement in my style of writing to get my work up to publishable quality (assuming that the content is good enough)?

Answers which summarize tips from available, useful resources are welcome.
Two good primers specifically on the subject of mathematics, which is quite different from more empirical sciences in many of its conventions:


Paul Halmos’s How to write mathematics is a classic — still excellent, if slightly old-fashioned in some ways.
Terence Tao’s blog post On writing collects and summarises links to some excellent advice from himself and others.
