Physics is a natural science that includes the study of matter, energy, force and motion through space and time. Generally, it conducts analysis of nature to understand how universe works. The boundaries of physics are not clearly and strictly defined as it intersects with other many disciplines such as quantum chemistry and biophysics. It often explains fundamental mechanisms of philosophy and mathematics.
Physics give significant contributions that pave way our advances especially in technology. Breakthroughs in nuclear physics or electromagnetism led to hi-tech and modern televisions, computers, appliances and nuclear weapons. Thermodynamics move forward the industrialization of our world and advances in mechanisms led to calculus development.
The contemporary thinkers in early Europe used experimental and quantitative methods to discover laws of physics. Newton, Galileo and Kepler unified the different laws of motion. As the demand for energy increased during the industrial revolution, research for energy also flourished thus discovered the laws in chemistry, thermodynamics and electromgnetics. This study observes energy and matter on normal scale.
This era started with Max Planck’s work in quantum theory and Einstein’s work in relativity. It was carried on by Heisenberg, Schrodinger and Paul Dirac’s quantum mechanics. In this study, energy and matter are observed on gigantic or miniscule scale or in extreme conditions.
