Scientific language that is correct and serious so far as teachers and students are concerned must follow these stylistic norms

Be as verbally explicit and universal as possible....The effect is to make `proper' scientific statements seem to talk only about an unchanging universal realm.... | Avoid colloquial forms of language and use, even in speech, forms close to those of written language. Certain words mark language as colloquial..., as does use of first and second person... | Use technical terms in place of colloquial synonyms or paraphrases.... | Avoid personification and use of specifically or usually human attributes or qualities..., human agents or actors, and human types of action or process... | Avoid metaphoric and figurative language, especially those using emotional, colorful, or value laden words, hyperboles and exaggeration, irony, and humorous or comic expressions. | Be serious and dignified in all expression of scientific content. Avoid sensationalism. | Avoid personalities and reference to individual human beings and their actions, including (for the most part) historical figures and events.... | Avoid reference to fiction or fantasy. | Use causal forms of explanation and avoid narrative and dramatic accounts…. Similarly forbidden are dramatic forms, including dialogue, the development of suspense or mystery, the element of surprise, dramatic action, and so on.
