Physics is the study of matter, motion, and energy of constituents of the observable universe using the language of mathematics with the aim to find a unified set of laws that govern matter, motion, and energy at subatomic, macroscopic, and very large length scales. The Physics Research Network on SSRN is an open-access preprint server that provides a venue for authors to showcase their research papers in our digital library, speeding up dissemination and providing the scholarly community access to groundbreaking working papers and early-stage research. SSRN provides the opportunity to share different outputs of research such as preprints, preliminary or exploratory investigations, book chapters, PhD dissertations, course and teaching materials, presentations, and posters, among others. SSRN also helps physics scholars discover the latest research in their own and other fields of interest while providing a platform for the early sharing of their own work, making it available for subsequent work to be built upon more quickly.
Discoveries in physics have enabled an understanding of physical phenomena in many disciplines, including astronomy, biology, engineering, materials science, medicine, and the life sciences. Furthermore, the mathematical framework developed from these discoveries has led to applications in the social sciences, such as economics. Scholars and researchers in physics address a wide range of challenges; from finding fundamental laws that govern the very small (subatomic) to very large (universe) length scale systems to addressing issues impacting humanity and its surroundings. Examples include finding the fundamental law unifying General Relativity and Quantum mechanics, new materials and methods to efficiently generate and manipulate all forms of energy, and devising engineering solutions to improve human life, survivability, and living conditions.
