Physics is the study of matter and the motion through space and time. Physics is concerned with energy, force, the analysis of nature and how the universe behaves on many levels. It is one of the oldest academic studies. There are many concepts in physics which explain the fundamental principles of other sciences. Physics is referred to as the linking science to other disciplines.
During the industrial revolution energy needs increased; research in the fields of physics and thermodynamics expanded. In this period of time, the laws of thermodynamics, chemistry and electromagnetics were discovered. These strives in science led to the invention of the steam engine and later to the combustion engine used in vehicles.
Modern physics is concerned with the behavior of matter and energy under extreme conditions such as small and large scales. The modern study of physics was revolutionized by the physicist Max Planck. Mac Planck had ground breaking work in quantum theory. Albert Einstein had contributions to modern physics by his work in relativity. An example of modern physics is atomic and nuclear physics.
Physics covers a wide range of phenomena. These can range from elementary particles to super clusters of galaxies. Physics tries to describe various phenomena that occur in nature in terms of more simple models. Physics tried to connect the things observable to humans to their causes and make connections to things observed in everyday life.
Categories within Physics:
Applied physics, also known as engineering physics, is the connecting study between physics as a pure science, mathematics and engineering.
Astrophysics is a branch of astronomy that deals with physics of the universe.
Molecular physics is the study of physical properties of molecules.
Nuclear physics is a branch of physics that looks at the constituents and interactions of atomic nuclei.
Classical mechanics is one of the two major sub-fields of mechanics.
Condensed matter physics is the field of physics that deals with physical and molecular properties of condensed phases of matter.
Electricity and Magnetism is a field in physics which looks at the effects on electricity and magnetism on the environment.
Fluid dynamics is the study of fluid flow. It has two subdisiciplines, aerodynamics and hydrodynamics.
Mathematical physics is the study of mathematical methods for application of problems in physics.
Particle physics is an area of physics that studies the nature of particles.
Quantum physics is a branch of physics which deals with physical phenomena’s at microscopic scales, where the action is on the other of Planck constant.
Thermodynamics is a branch of natural science concerned with heat and its relation to energy and work.
Hearing is the ability to perceive sounds by detecting vibrations or changes in pressure through the ear.
Optics is the branch of physics that deals with light and vision.
Physics, because it is a quantitative science, requires several measurements taken during experiments.
Physics experiments can range from a simple tossing of a ball to experiments on Bose-Einstein Condensate.
The main focus of this book is how to find solutions to the Schrodinger equation, an important part of any introductory course in quantum mechanics. First we introduce and derive both the time-dependent and time-independent versions of the Schrodinge... READ MORE »
Variables in Science Experiments
- A variable that is changed on purpose, by the scientist; the scientist controls it; the plan he/she sets up or changes to make the experiment work:
