A scientific reference is a citation that provides detailed information about a source used in research or academic writing. It allows readers to locate the original work, ensuring transparency and credibility in the presented information. Scientific references typically include the author's name, publication year, title of the work, and where it can be found, such as a journal or book. In scientific fields, proper referencing is crucial for acknowledging the contributions of other researchers, like Albert Einstein or Marie Curie. It also helps to avoid plagiarism, as it shows respect for the intellectual property of others while supporting the validity of one's own findings.
