Pure science in the context of "Engineering physics"

Space physics, also known as space plasma physics, is the study of naturally occurring plasmas within Earth's upper atmosphere and the rest of the Solar System. It includes the topics of aeronomy, aurorae, planetary ionospheres and magnetospheres, radiation belts, space weather, solar wind, the Sun, and more recently the Interstellar medium.

Space physics is both a pure science and an applied science, with applications in radio transmission, spacecraft operations (particularly communications and weather satellites), and in meteorology. Important physical processes in space physics include magnetic reconnection, plasma waves and plasma instabilities. It is studied using direct in situ measurements by sounding rockets and spacecraft, indirect remote sensing of plasmas with radar (through methods such as Incoherent scatter and GPS scintillation), and theoretical studies using models such as magnetohydrodynamics (fluid theory), or kinetic theory.

Scientific writing is about science, with the implication that the writing is done by scientists and for an audience that primarily includes peers—those with sufficient expertise to follow in detail. (The similar term "science writing" instead refers to writing about a scientific topic for a general audience; this could be by scientists and/or journalists, for example.) Scientific writing is a specialized form of technical writing, and a prominent genre of it involves reporting about scientific studies such as in articles for a scientific journal. Other scientific writing genres include writing literature-review articles (also typically for scientific journals), which summarize the existing state of a given aspect of a scientific field, and writing grant proposals, which are a common means of obtaining funding to support scientific research. Scientific writing is more likely to focus on the pure sciences compared to other aspects of technical communication that are more applied, although there is overlap. There is not one specific style for citations and references in scientific writing. Whether one is submitting a grant proposal, literature review articles, or submitting an article into a paper, the citation system that must be used will depend on the publication they plan to submit to.

English-language scientific writing originated in the 14th century, with the language later becoming the dominant medium for the field. Style conventions for scientific writing vary, with different focuses by different style guides on the use of passive versus active voice, personal pronoun use, and article sectioning. Much scientific writing is focused on scientific reports, traditionally structured as an abstract, introduction, methods, results, conclusions, and acknowledgments. However, one of the founders of the Royal Academy, Thomas Sprat, also saw connections between scientific writing and writing in the humanities.
