What is Terminology: Definition and 179 Discussions

Terminology is a general word for the group of specialized words or meanings relating to a particular field, and also the study of such terms and their use. This is also known as terminology science. Terms are words and compound words or multi-word expressions that in specific contexts are given specific meanings—these may deviate from the meanings the same words have in other contexts and in everyday language. Terminology is a discipline that studies, among other things, the development of such terms and their interrelationships within a specialized domain. Terminology differs from lexicography, as it involves the study of concepts, conceptual systems and their labels (terms), whereas lexicography studies words and their meanings.
Terminology is a discipline that systematically studies the "labelling or designating of concepts" particular to one or more subject fields or domains of human activity. It does this through the research and analysis of terms in context for the purpose of documenting and promoting consistent usage. Terminology can be limited to one or more languages (for example, "multilingual terminology" and "bilingual terminology"), or may have an interdisciplinarity focus on the use of terms in different fields.

    Understanding of Voltage potential

    I am bit confused with voltage potential terminology again to basics When it is referred as Voa it is Voltage of "o" wrt "a". Is it correct? But other major question is as per the document I would have written KVL as Voa - I1 * Z = Vn. I am really confused with notation used.

    If we have a set of variables ##x_1, x_2, ...x_n ## what does it mean to say that "##G## is only a function of ##x_1,x_2,x_3##"? My thoughts: Context 1: The function ##G## has been previously defined. In Context 1, saying "##G## is only a function of ##x_1,x_2,x_3##" means the same thing as...

    One can have a progression and it is called a Sequence. One can sum the terms in a sequence or progression, and this is called a Series. Why those terms like that; or why those two different terminologies? Was it decided just to pick a word Series so as to avoid the need to use Sum Of the...

    Hi all, this is just a terminology question. I am aware of the definition of "proper time" (and "proper length") in the context of special relativity. I recently heard the term "improper time", as opposed to proper time, of course. Is that accepted terminology? Sounds weird to me.

    Entropy: why measure disorder?

    Something I've always wondered: why do we measure the amount of disorder (entropy) rather than the amount of order? We don't measure brightness by the amount of "dark". Surely order is the thing of interest, so why don't we measure that rather than measuring the absence of it? And in...

    Understanding laser power terminology

    I see that many LIDAR systems use power in the millijoule range in atmospheric research. A typical number is 25 millijoules. 25 millijoules is equal to 25 milliwatt/seconds. This means 25 milliwatts for one second. This seems like a tiny amount of power, yet a 25 millijoule laser costs many...

    Confusion With Blackbody Radiation
