✅ 1- In this book I aim to describe most of what a scientist needs to know about mathematical writing.

✅ 2- Although the emphasis is strongly on mathematical
writing, many of the points and issues I discuss are relevant to scientific writing in general.

✅ 3- My main target audience is graduate students. They often have little experience or knowledge of technical writing and are daunted by the task of writing a report or thesis.


✅ 4- The advice given here reflects what I have learned in the ten years since I wrote my first research report as a
graduate student and describes what I would have liked to know as I started to write that first report.

✅ 5- I hope that as well as being a valuable resource
for graduate students, this book will also be of use to practising scientists.

👨‍🏫 دقت بکنید در ریاضی نویسنده دوست ندارد یک نتیجه را بیان کند، بلکه به صورت ضمنی از خواننده انتظار می رود خود نتیجه گیری کند. لذا فعل imply یعنی نتیجه گیری غیرمستقیم استفاده می کند تا ذهن خواننده را به چالش بکشاند و ... معادل دیگری برای آن infer است. احتمالا با صفات implicit و explicit آشنایی دارید! این صفات هم دقیقا به همین منظور بکار می روند.
