A scientific paper is a written document that presents original research findings or reviews existing knowledge on a specific topic. It typically includes sections such as an abstract, introduction, methods, results, and discussion. These papers are often published in academic journals and are essential for sharing discoveries within the scientific community. The purpose of a scientific paper is to communicate research clearly and allow other scientists to evaluate, replicate, or build upon the work. Peer review is a critical process where experts in the field assess the paper's quality and validity before publication, ensuring the integrity of scientific knowledge.
