Chapter 1 What I s Scientific Writing? Beauty of style and harmony and grace and good rhythm depend on simplicity. -Plat0 THE NEED FOR CLARITY What is scientific writing? I believe that the key to scientific writing is clarity. Successful scientific experimentation is the result of a clear mind attacking a clearly stated problem and producing clearly stated conclusions. Ideally, clarity should be a characteristic of any type of communication; however, when something is being said for the first tim e, clarity is essential. Most scientific papers, those published in our primary research journals, are accepted for publication precisely because they do contribute new knowledge. Hence, we should demand absolute clarity in scientific writing. RECEIVING THE SIGNALS Most people have no dcubt heard this question: If a tree falls in the forest, and there is no one there to hear it fall, does it make a sound? The correct answer is no. To un ders tand this, w e need to consult a dictionary. Webster's Ninth New Collegiate Dictionary gives as the first two definitions of "soundn: " 1 a : the sensation perceived by the sense of hearing b : a particular auditory impres- sion." Thus, sound is more than "pressure waves," and indeed h e an be no sound without a hearer. And, similarly, scientific commun ication is a two -wa y process . Just as a signal of any kind is useless unless it is perceived, a published scientific paper (signal) is useless unless it is both re-

porary existence the specialist who is trained but uneducated,
technically skilled but culturally incompetent, is a menace."Although the ultimate result of scientific research is publica-
tion, it has always amazed me that so many scientists neglect theresponsibilities involved. A scientist will spend months or years ofhard work to secure data, and then unconcernedly let much oftheir value be lost because of lack of interest in the communica-tion process. The same scientist who will overcome tremendousobstacles to carry out a measurement to the fourth decimal placewill be in deep slumber while a secretary is casually changing
micrograms per milliliter to milligrams per milliliter and while thecompositor slips in an occasional pounds per barrel.English need not be difficult. In scientific writing, we say
"The best English is that which gives the sense in the fewest shortwords" (a dictum printed for some years in the "Instructions toAuthors" of the Journal of Bacteriology). Literary tricks, metaphorsand the like, divert attention from the substance to the style. Theyshould be used rarely, if at all, in scientific writing.

The earliest book we know of is a Chaldean account of theFlood. This story was inscribed on a clay tablet in about 4,000B.C., antedating Genesis by some 2,000 years (48).
A medium of communication that was light weight and porta-ble was needed. The first successful medium was papyrus (sheetsmade from the papyrus plant and glued together to form a rollsometimes 20 to 40 ft long, fastened to a wooden roller), whichcame into use about 2,000 B.C. In 190 B.C. parchment (made
from animal skins) came into use. The Greeks assembled largelibraries in Ephesus and Pergamum (in what is now Turkey) andin Alexandria. According to Plutarch, the library in Pergamumcontained 200,000 volumes in 40 B.C. (48).
ID. 105 A.D. the Chinese invented paper, the modem mediumof communication. However, because there was no effective wayof duplicating communications, scholarly knowledge could not be
widely disseminated.Perhaps the greatest single invention in the intellectual history
of mankind was the invention of the printing press. Althoughmovable type was invented in China in about 1100 A.D. (48), theWestern World gives credit to Gutenberg, who printed his 42-lineBible from movable type on a printing press in 1455 A.D. Gu-tenberg's invention was effectively and immediately put to use
throughout Europe. By the year 1500, thousands of copies ofhundreds of books (called "incunabulaw) were printed. ,
The first scientific journals appeared in 1665, when coinciden-tally two different journals commenced publication, the Journal
des Scavans in France and the Philosophical Transactions of theRoyal Society of London in England. Since that time, journals haveserved as the primary means of communication in the sciences.Currently, some 70,000 scientific and technical journals are pub-lished throughout the world (30).
THE IMRAD STORY
The early journals published papers that we call "descriptive."
Typically, a scientist would report that "First,I
saw this, and thenI saw thatn or "First, I did this, and ther? I did that." Often theobservations were in simple chronological order.
This descriptive style w ~ sppropriate for the kind of sciencethen being reported. In fact, this straightforward style of reportingis still used today in "lettersn journals, in case reports in medicine,and in geological surveys, etc.

Without publication, science is dead. --Gerard Pie1
DEFINITION OF A SCIENTIFIC PAPERA scientific paper is a written and published report describingoriginal research results. That short definition must be qualified,however, by noting that a scientific paper must be written in acertain way and it must be published in a certain way, as definedby three centuries of developing tradition, editorial practice, sci-entific ethics, and the interplay of printing and publishing proce-dures.
To properly define "scientific paper," we must define themechanism that creates a scientific paper, namely, valid publica-tion. Abstracts, theses, conference reports, and many other types ofliterature are published, but such publications do not normallymeet the test of valid publication. Further, even if a scientificpaper meets all of the other tests (discussed below), it is notvalidly published if it is published in the wrong place. That is, arelatively poor research report, but one that meets the tests, isvalidly published if accepted and published in the right place (a
primary journai, usually); a superbly prepared research report isnot validly published if published in the wrong place. Most of thegovernment report literature and conference literature, as well asinstitutional bulletins and other ephemeral publications, do notqualify as primary literature.
Many people have struggled with the definition of primarypublication (valid publication), from which is derived the defini-tion of scientific paper. The Council of Biology Editors (CBE), an
8/8/2019 1 How to Write and Publish a Scientific Paper
authoritative professional organization (in biology, at least) dealing
with such problems, amved at the following definition (19):
An acceptable primary scientific publication must be the first disclo-sure containing sufficient information to enable peers (1) to assessobservations, (2) to repeat experiments, and (3) to evaluate intellec-tual processes; moreover, it must be susceptible to sensory perception, essentially permanent, available to the scientific communitywithout restriction, and available for regular screening by one ormore of the major recognized secondary services (e.g., currently,Biological Abstracts, Chemical Abstracts, Index Medicus, ExcerptaMedica, Bibliography of Agriculture, etc., in the United States andsimilar services in other countries).
At first reading, this definition may seem excessively complex,
or at least verbose. But .those of us who had a hand in drafting it
weighed each word carefully, and we doubt that an acceptable
definition could be provided in appreciably fewer words. Because
it is important that students, authors, editors, and all others con-
cerned understand what a scientific paper is and what it is not, it
may be helpful to work through this definition to see what it really
means.
"An acceptable primary scientific publication" must be "the
first disclosure." Certainly, first disclosure of new research dataoften takes place via oral presentation at a scientific meeting. But
the thrust of the CBE statement is that disclosure is more than
disgcrgement by the author, effective first disclosure is accom-
plished only when the disclosure takes a form that allows the peers
of the author (either now or in the future) to fully comprehend
and use that which is disclosed.
Thus, sufficient information must be presented so that poten-
tial users of the data can (i) assess observations, (ii) repeat experi-
ments, and (iii) evaluate intellectual processes (are the author'sconclusions justified by the data?). Then, the disclosure must be
"susceptible to sensory perception." This may seem an awkward
phrase, because in normal practice it simply means publication;
however, this definition provides for disclosure not just in terms
of visual materials (printed journals, microfilm. microfiche) but
also perhaps in nonprint, nonvisual forms. For example,
"publication" in the form of audio cassettes, if that publication
met the other tests provided in the definition, would constitute
effective publication. In the future, it is quite possible that first
disclosure will be entry into a computer data base.

Regardless of the form of publication, that form must beessentially permanent, must be made available to the scientificcommunity without restriction, and must be made available to the
inform ation retrieval services (Biological Abstracts. Chem ical A bstracrs, Ind ex Medicus, Science Citation Index, etc.). Thus, publica-tions such as newsletters and corporate publications, many ofwhich are of value for their news or other features, cannot serve asrepositories for scientific knowledge.
To restate the CBE definition in simpler but not more ac-curate terms, primary publication is (i) the first publication oforiginal research results, (ii) in a form whereby peers of the authorcan repeat the experiments and test the conclusions, and (iii) in a.journal or other source document readily available within thescientific community. To understand this definition, however, wemust add an important caveat. The part of the definition thatrefers to "peers of the author" is accepted as meaningprepublication peer review. Thus, by definition, scientific papersare published in peer-reviewed publications.
I have belabored this question of definition for two reasons.First, the entire community of science has long labored wiih aninefficient, costly system of scientific communication precisely be-cause it (authors, editors, publishers) has been unable or unwilling
to define primary publication. As a result, much of the literature isburied in meeting abstracts, obscure conference reports, govern-ment documents, or in books or journals of m i~ u sc u le irculation.Other papers, in the same or slightly altered form, are publishedmore than once; occasionally, this is due to the lack of definitionas to which conference reports, books, and compilations are (orshould be) primary publications and which are not. Redundancyand confusion result. Second, a scientific paper is, by definition, aparticular kind of document containing certain specified kinds ofinformation. A scientific paper "demands exactly the same
qualities of thought as are needed for the rest of science: logic,clarity, and precision" (50). If the graduate student or the buddingscientist (and even some of those scientists who Gave alreadypublished many papers) can fully grasp the significance of thisdefinition, the writing task should be a good deal easier. Confusionresults from an amorphous task. The easy task is the one in whichyou know exactly what must be done and in exactly what order it
