Writing scientifically is writing precisely and clearly. Scientific writing is concerned with the recording of measurements and the results of observations. Writing precisely therefore means the complete absence of words such as “almost” or “very” in the description of events. Instead you should use precise descriptions such as “98.2% complete”. A good hint is to make sure that every word counts and that no word is unnecessary. This is good advice in all writing but particularly in scientific writing where the writing is concerned with measurements, observations, and the conveying of quantitative or qualitative results.
