29 July – 1 August
Writing for a Technical Audience
 Purpose: To Inform
 Aspects
 Structure
 Choice of Material
 Organization of Ideas
 Depth of Detail
 Style
 Grammatical Structure
 Word Choice
 Caveat: Don’t Lose the Reader!
A Technical Writer Is NOT:
 J.K. Rowling
 Kid at summer
camp
 Norah Roberts
 Peter Mayle
 Ken Follett
 Dan Brown or Iain
Pears
 Alexandre Dumas
 Thomas Hardy or
Charles Dickens
 Emily Bronte
 D.H. Lawrence
 Cervantes
 Artur Perez-Reverte
or Franz Kafka
 Leo Tolstoy
A Technical Audience is NOT:
On a QUEST
 Challenge to
participate
 Obstacles to
overcome, each
more difficult than
the one before
 Prize for success
 Penalty for failure
 Keywords


Title
Abstract
Introduction
Body of article
 Section by section
 Result
 Theorem
 Discussion/Conclusion
Starting Point
 Decide Purpose






Breakthrough (ground-breaking) – new formulation to
solve old or new open problem
Progress / development – often new methodology or
extension to higher dimension, a new context, or relaxation
of assumptions
Comparison of existing methods with/without modification
Reprise – new more elegant proof of known result yielding
greater insight, often entirely new technical approach
Illustration – application to real problem/ data of
importance, typical of other applications
Scientific result – not primarily statistical innovation
 Identify Major Results
 Determine Audience
Structure: Logical
Introduction
Problem Statement
in Technical Form
Sequence of Lemmas
and Theorems

comes next

Choice of Material
 Space allocation – by importance
 Of result and its consequences
 For making reasoning transparent
 Critical steps and keys to solution
 Proofs

“Substitute (#.#) into (#.##) and apply Green’s theorem”

“Noting that (#.#) can be rewritten as a mixed model with
correlated error structure, partitioning by . . . gives”
 Construction / derivation of methodology
 Application – orderly analysis

Principle finding through consequences
 OTHERWISE: Skip the obvious and summarize


 “By straightforward but tedious algebra. . . “
 Following the proof by ***** in (reference)
NOT by chronology of research
NOT by pain of obtaining result
Introduction


Goals
 Convey Importance, Impact of research results

Attract readers


General Context
 What is the problem?
 Why care about the work?
Technical Context
 What was already known?
 What was the gap (before this paper)?
Contribution of this paper
 What is the approach to (nature of) the solution?
Outline of paper – “Signposts”


Natural choices, signal papers – not entire literature review
Citation without interrupting flow of text
Content



References within text
Style:
Transparent, Clear, Precise,
Parsimonious, Concise, Spare, Lean, Direct
 Overall Impression
 “Careful writing reflects careful work”
 Precise word usage – Standard English
 1:1 Word:Concept
 Precise notation usage
 Definition before first use of notation or symbol
 1:1 Notation:Definition
 Numbered for internal referencing throughout text (as
appropriate)
 Repeated (brief) definition for delayed use or for
modification (e.g., dropping subscript)
 Grammar!
 Spell and grammar check


Useful
Neither Necessary nor Sufficient
 References: Strunk & White
Style:
Transparent, Clear, Precise,
Parsimonious, Concise, Spare, Lean, Direct

Effective Writing

Verbs


ACTIVE not passive when possible
Correct verb tenses





Clear Sentences


CONSISTENT voice – either 1st person (“I” or “we”) or 3rd person
USE PARALLEL structure for series



Data Exist – Present (NOTE: Data ARE - plural)
Papers Exist – Present
Experiments End – Past
Theorems Hold - Present
Series of sentences
Series within sentences – clauses, verbs, objects

DISENTANGLE complex sentences



Equations
Figures – all types
Definitions – if referred to later, especially for section-long gap
Reference numbering
Style:
Transparent, Clear, Precise,
Parsimonious, Concise, Spare, Lean, Direct
 “Do Not Litter”
 DELETE: Wasted sentences




Vague, overly general
Only approximately (not precisely) true
Unnecessarily repetitive
“Mixed models are important to many areas of
application.”
 DELETE: Wasted phrases and words
 “It is easy to see that. . .”
 “In order to. . .” (“To” almost always suffices)
 Most adjectives, especially judgmental, emotional
 REPLACE: Non-standard English
 Personal words . . . You are not [yet] Tukey
 Cute / funny / trendy / jargon /TXT expressions
