Study Notes
Definition of Physics
- Physics is the natural science of matter, involving the study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force.
Importance of Physics
- Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves.
Physicists
- A scientist who specializes in the field of physics is called a physicist.
History of Physics
- Physics is one of the oldest academic disciplines and, through its inclusion of astronomy, perhaps the oldest.
- Over much of the past two millennia, physics, chemistry, biology, and certain branches of mathematics were a part of natural philosophy.
- During the Scientific Revolution in the 17th century, these natural sciences emerged as unique research endeavors in their own right.
Interdisciplinary Research
- Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry.
- The boundaries of physics are not rigidly defined.
Impact of Physics
- New ideas in physics often explain the fundamental mechanisms studied by other sciences and suggest new avenues of research in these and other academic disciplines such as mathematics and philosophy.
- Advances in physics often enable new technologies.
