Definition of “Physics” by the Oxford English Dictionary. “A branch of physics that studies the universe and its structure and workings, focusing on the behaviour of economical matter.” The subject matter of physics often includes astronomy, mathematics, as well as the behaviour of real objects.
The study of physics is divided into four areas, including solid-state physics, condensed-matter physics, classical physics, and quantum physics. In addition to studying the subject matter of physics students should have good reasoning skills and enjoy working in a group.
Quantum Physics is one of the most fascinating areas of physics. It deals with the properties of space and time that are governed by quantum laws. Albert Einstein was responsible for revolutionary results with his Theory of Relativity, which posed a challenge to the belief of many scientists that space and time are completely random. Physicists have since then been testing the predictions of this theory with experimental results that have been consistent over the years.
Another branch of physics that is also interesting to those of us who are not interested in how things work is solid-state physics. This is the area of physics that studies the internal structures of solids, such as diamonds, quarks, bosons, protons, and molecules. Unlike the previous branches of physics, solid-state physics does not deal with the behavior of subatomic particles. Instead, it is interested in the properties of atoms and their interactions with one another.
Two other important branches of physics are condensed physics. With condensed physics, this field deals with those small, atomically-sized objects that are too large to be seen by the human eye. They use methods such as radiation and vacuum to study these objects. Particles in condensed fields, such as gases and fluids, often have surprising similarities to the molecules that compose the solid matter.
Another branch of natural sciences dealing with the matter is the nuclear physics field. Nuclear physics is related to the elements that make up an atom and to the process by which these elements are made in the atom. The outcome of this process is the knowledge of the makeup of the atom and the ultimate structure of the universe. There are two main branches of this subject: condensed physics and nuclear physics. Although condensed physics describes many of the same phenomena as those described by both branches of physics, the topics are different enough that they are best studied separately.
The last major branch of physics is condensed mechanics. This branch of science deals specifically with matter and its properties, in all its forms. One branch of this field deals specifically with the matter in the solid state; another branches deals with the matter in a semi-solid form. A third branch is a complete non-Newtonian system of physics in which even matter cannot be completely understood, including light, electromagnetism, and gravity. Although most of the phenomena of the natural world are the products of condensed mechanics, it does not include sub branches like those of condensed matter. In particular, it does not deal with the problem of unification, which puzzles many physicists today.
All three branches of physics have been deeply affected by classical music, especially piano and organ music. The harmony and progress of the pieces are often described using simple harmonic and musical language, a feat unachievable by other branches of physics. The most popular form of music used in teaching students to recognize and appreciate music is instrumental music. Not only do the pieces provide a rich learning experience, but the methods of playing them also have profound influences on how music is perceived. Thus, the study of music, and its creation, are one of the most important branches of modern physics.
Apart from the three mentioned branches, modern physics has four other branches: optics, particle, and field theory, electrodynamics, and relativity. The major difference between these branches is that they are mostly concerned with different aspects of nature, rather than with the entire subject. While the former deals mainly with how matter behaves, the latter branches attempt to understand more about the connections among different matter particles and the laws that govern their interactions.
