What is physics and how does it shape our understanding?

Physics is a fundamental natural science that investigates matter, its motion and behavior through space and time, along with energy and force. Historically part of natural philosophy, physics emerged as a distinct scientific discipline during the Scientific Revolution in the 17th century. Discoveries in this field drive technological revolutions, from industrialization powered by thermodynamics to modern computing enabled by solid-state and nuclear physics.

What we know

• Physics is defined as the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and related concepts like energy and force. [2, 3]
• During the 17th-century Scientific Revolution, physics branched away from natural philosophy to become a separate research endeavor alongside chemistry, biology, and certain branches of mathematics. [3]
• Advances in thermodynamics directly enabled the development of industrialization. [3]
• The Solvay Conferences, beginning with the historic invitation-only gathering in 1911, have been dedicated to preeminent unsolved problems in physics and chemistry. [5]

Still open

• The exact boundaries of physics are not rigidly defined as it frequently intersects with many interdisciplinary areas of research.
