Physics (from Ancient φυσική (ἐπιστήμη), physikḗ (epistḗmē), lit. 'knowledge of nature', from φύσις phýsis 'nature')[1][2][3] is that the science that studies matter,[4] its motion and behavior through space and time, and therefore the related entities of energy and force.[5] Physics is one among the foremost fundamental scientific disciplines, and its main goal is to know how the universe behaves.[a][6][7][8]
Physics is one among the oldest academic disciplines and, through its inclusion of astronomy, perhaps the oldest.[9] Over much of the past two millennia, physics, chemistry, biology, and certain branches of mathematics were a neighborhood of physics , but during the Scientific Revolution within the 17th century these natural sciences emerged as unique research endeavors in their title .[b] Physics intersects with many interdisciplinary areas of research, like biophysics and quantum chemistry, and therefore the boundaries of physics aren't rigidly defined. New ideas in physics often explain the elemental mechanisms studied by other sciences[6] and suggest new avenues of research in academic disciplines like mathematics and philosophy.
Advances in physics often enable advances in new technologies. for instance , advances within the understanding of electromagnetism, physics , and atomic physics led on to the event of latest products that have dramatically transformed modern-day society, like television, computers, domestic appliances, and nuclear weapons;[6] advances in thermodynamics led to the event of industrialization; and advances in mechanics inspired the event of calculus.
