There are many different branches of modern physics, including astrophysics, nuclear physics, biophysics, mathematical physics, as well as optical and laser physics. Physics is the study of matter and energy and how they relate and interact through space and time, which also includes more theoretical branches such as high-energy experimental physics.Continue Reading
Astrophysics is the branch concerned with the physics of the universe, including how planets, stars and other celestial bodies are created and how they interact with each other. Astrophysicists study such things as black holes, galaxies, supernovas and the expansion of the universe.
Biophysics is a relatively new field that combines physics and biology, which looks at such things as how brains, enzymes, proteins and other natural structures function. Biophysicists are primarily concerned with the physical reactions involved in various biological processes that occur in either animals or plants.
Mathematical physics is sometimes considered the basis of all physics, as the discipline wouldn't be possible without it. Optical and laser physics has resulted in some of the most important technological innovations such as X-rays, while nuclear physics is responsible for nuclear energy and nuclear bombs. High-energy experimental physics has branched out from nuclear physics, as it studies the reactions between matter and radiation.Learn more about Physics
In the theory of relativity in the study of physics, the interval between two events is called proper time. Proper time is based on a clock that measures both events.Full Answer >
In physics, energy is a system's capacity to perform work, which is force acting on an object. Energy has many forms, including kinetic or mechanical energy, potential energy, light energy and heat energy. The basic rules for understanding energy are the laws of thermodynamics.Full Answer >
Some potential investigatory projects that are related to physics include investigating whether repulsorlifts can be used as a method of stable, magnetic levitation, constructing a free-fall apparatus in the absence of equipment, the use of para-toluenesulfonate-doped polypyrolle as an EMF electrode source, and using elastomeric grating for wavelength switching. These are projects or experiments that have been previously carried out and may be repeated to compare results.Full Answer >
There are many physics jokes, such as the atoms and electron anecdote. Two atoms bump into each other. One says, "I have lost an electron!" The other asks, "Are you sure?" The first replies, "Yes, I'm positive."Full Answer >
