Meaning of QED
The meaning of QED is essentially that whatever has been stated before is an indisputable fact. This abbreviation can be found in many areas ranging from mathematics and science to philosophy and literature. In mathematics, it typically implies the end of one's proof for a theorem or equation. In scientific writing documents, QED can often be found at the end of experiments to signify that results have been thoroughly tested and verified. It is also often seen in philosophical texts as a conclusion to arguments or statements about life or ethics. In literature too, it is sometimes used as an indication that an author may be citing something they are certain of or can prove as fact with reasonable evidence or logic.
Use Cases
QED is commonly used in academic publications such as research papers or essays to indicate something which has been proven through logical reasoning, data collection, experimentation, etc., and therefore should not require further debate or discussion on its veracity. The phrase is also occasionally encountered in casual conversation when someone wants to emphasize their certainty about something they've said; for example they might say “What I'm saying makes perfect sense - QED” if they feel their point requires no further elucidation on their part. Finally, because QED has spread beyond strictly academic circles over time, some people may use it humorously when referring jokingly to conclusions which seem obvious but which don't actually require any real proof - like a pun intended only for themselves!
