Theoretical Physics Homework: Physics Fields
Did you know that physics has different fields? Yes, physics can be applied in so many various fields that we shall discuss in this article. Hence if you love physics, stick around as your dream field might be one of the many different physics fields. We shall also cover what physics entails and why it is a pretty important subject to master.
Physics in a nutshell
Physics is a science branch that focuses on the properties and nature of things that are non-living. It also focuses on the energy which is not tackled in biology and chemistry, plus the material universe’s fundamental laws. Physics is hence a pretty diverse and exciting subject. Due to this diversity, it opens doors to multiple fields that we shall discuss later on.
The multiple physics fields also exist due to how vast the subject is. Most people tend to focus on a small bit of physics and gain mastery, hence developing a field. That means that you can choose to focus on a small but considerate bit of physics and still find a field that suits you without having to deal with all the physics laws that exist in the world.
Physics can be subdivided into 2 broad categories; this is based on physics history.
- Classical physics – consists of studies that rose from the Renascence up to the start of the twentieth century.
- Modern physics – studies that commenced in the twentieth century
Part of this division can be considered as scale. The modern physics concentrates on the tinier particle, broader laws, and more precision in measurement. All these factors help us further understand the inner working of the universe in a more complex manner.
Physics can also be subdivided into:
- Experimental – using materials practically
- Theoretical – building overarching laws which are based on the inner workings of the universe.
As you go through the many different fields in this article, you will realize that some of them overlap. That means that some of them seem similar in a way, hence do not be confused. For instance, the contrast between astrophysics, cosmology, and astronomy cab be pretty virtually meaningless sometimes to most people. Excluding the cosmologist, astrophysicists, and astronomers, who take these distinctions with a lot of seriousness.
Classical physics field
Before the commencement of the twentieth century, physics mainly focused on light, wave, and sound motion, mechanics study, electromagnetism, thermodynamics and heat. Some classical fields studied back in the 1900s include:
- Acoustics – focuses on sound waves and general sound.
- Astronomy – Space studying
- Chemical physics – studying the chemical system based on physics
- Computation physics – The use of computation to solve problems that are physics-based and for which some quantitative theory exists
- Electromagnetism – studying magnetic and electrical fields.
- Electronics – studying electron flow
- Fluid dynamics – studying the fluid physical properties
- Geophysics – studying the earth’s physical properties
- Math physics – applying math rigorously to solve physics-based questions
- Mechanics – studying body motions in a reference frame
Moden physics usually embraces atoms plus their parts, space exploration and cosmology, high-speed interaction and relativity, plus mesoscopic physics. The modern physics fields include:
- Astrophysics – Studying space’s objects as per their physical properties
- Atomic physics – studying atoms
- Biophysics – studying physics in the living
- Chaos – studying systems which have strong sensitivity as per initial conditions
- Cosmology – exploring the universe
- Cryophysics – analyzing low temp situation
- Crystallography – studying crystals
- Nuclear physic – studying the nucleus
- Lasers – studying laser’s physical properties
Physics is a pretty broad subject, plus it is also pretty interesting. We hope that this article has helped you identify the field you would like to venture into.
