FIELDS OF PHYSICS

Question: What are the Fields of Physics?
Answer:

Physics is a diverse area of study and in order to make sense of it scientists have been forced to focus their attention on one or two smaller areas of the discipline. This allows them to become experts in that narrow field, without getting bogged down in the sheer volume of knowledge that exists regarding the natural world.
Below is a list - by no comprehensive - of different disciplines of physics. The list will be updated with new additions and definitions as appropriate.

* Acoustics - the study of sound & sound waves

* Mathematical Physics - applying mathematically rigorous methods to solving problems within physics

* Mechanics - the study of the motion of bodies in a frame of reference

* Meteorology / Weather Physics - the physics of the weather

* Molecular Physics - the study of physical properties of molecules

* Nanotechnology - the science of building circuits and machines from single molecules and atoms

* Nuclear Physics - the study of the physical properties of the atomic nucleus

* Optics / Light Physics - the study of the physical properties of light

* Particle Physics - the study of fundamental particles and the forces of their interaction

* Plasma Physics - the study of matter in the plasma phase

* Quantum Electrodynamics - the study of how electrons and photons interact at the quantum mechanical level

* Quantum Mechanics / Quantum Physics - the study of science where the smallest discrete values, or quanta, of matter and energy become relevant

* Quantum Optics - the application of quantum physics to light

* Quantum Field Theory - the application of quantum physics to fields, including the fundamental forces of the universe

* Quantum Gravity - the application of quantum physics to gravity and unification of gravity with the other fundamental particle interactions

* Relativity - the study of systems displaying the properties of Einstein's theory of relativity, which generally involves moving at speeds very close to the speed of light

* Statistical Mechanics - the study of large systems by statistically expanding the knowledge of smaller systems

* String Theory / Superstring Theory - the study of the theory that all fundamental particles are vibrations of one-dimensional strings of energy, in a higher-dimensional universe

* Thermodynamics - the physics of heat

It should become obvious that there is some overlap. For example, the difference between astronomy, astrophysics, and cosmology can be virtually meaningless at times ... to everyone, that is, except the astronomers, astrophysicists, and cosmologists, who can take the distinctions very seriously.

THEORIES

Theoretical Physics

Physics theories provide the basis upon which all of physics is built. As more theories are presented, experiments test them, attempting to falsify them and ultimately prove them ... but before this process can begin, the theory has to exist.

1. Fundamentals of Theoretical Physics
2. Classical Physics Laws
3. Modern Astronomical Theories
4. Quantum Physics
5. A Theory of Everything - Quantum Gravity Theory

Fundamentals of Theoretical Physics

When attempting to develop of physical theory, scientists follow the concepts defined in the scientific method. These are not hard and fast rules, but rather a set of guidelines that remind the scientist that great care must be used in carrying out the study of science.

• Introduction to the Scientific Method
• Hypothesis, Model, Theory, and Law
• Idealized Models
• Five Great Problems of Theoretical Physics

Classical Physics Laws

Some theories have weathered the test of time and moved from the realm of theoretical conjecture to become a cornerstone of the very foundation of scientific knowledge.

• Major Laws of Physics
• Introduction to Newton's Laws of Physics
• Newton's Law of Gravity
• Kepler's Laws of Planetary Motion
• Laws of Thermodynamics

Modern Astronomical Theories

Astronomy is a field which has a great deal of questions ... probably because it's so darn big! From the beginning of the universe until now, the universe is full of questions and scientists continue to search for answers.

• Einstein's Theory of Relativity
• What Is the Big Bang Theory?
• What Is a Black Hole?

• What Is Hawking Radiation?
• Book Review - Endless Universe: Beyond the Big Bang
• Book Review - Many Worlds in One

Quantum Physics

The first half of the 20th century was spent refining quantum theory, which, along with Einstein's theory of relativity, represents the sum total of all of our knowledge about how matter and energy interact in the universe. The result? There are four basic interactions that can take place between particles.

• Quantum Physics Overview
• Fundamental Forces of Physics
• Wave Particle Duality
• Book Review - Quantum Enigma: Physics Encounters Consciousness

A Theory of Everything - Quantum Gravity Theory

One goal of modern physics, at least for some physicists, is to develop a comprehensive theory of everything, which reconciles gravity with the other three fundamental forces. Such a theory would have to define the nebulous boundary between Einstein's theory of relativity and quantum theory, and is thus referred to as a theory of quantum gravity.

EXPERIMENTAL

Physics Experiments

Physics is an experimental science, which means that the theories presented within its framework must ultimately make their way through the rigorous crucible of experimental verification. Some experiments require elaborate apparatus and expertise, but there are many basic scientific experiments which can be performed at home without much cost or technical proficiency.

1. Performing Physics Experiments
2. Basic Physics Experiments
3. Classic Physics Experiments

Performing Physics Experiments

Before starting a physics experiment, there are some basic principles that need to be taken into consideration. An experiment needs to be set up and analyzed in a very precise fashion to yield meaningful results. Planning in advance will help get results which prove or disprove the hypothesis in question.

• Introduction to the Scientific Method
• Hypothesis, Model, Theory, & Law
• Experimental Methods
• Idealized Models

Basic Physics Experiments

Many science experiments can be performed easily at home without elaborate equipment, technical expertise, or even scientific knowledge. These basic experiments fall in that category and can be used to help young learners explore the natural world around them.

• Rocket Balloon
• Surface Tension Experiments
• Cosmic Ray Detector

Classic Physics Experiments

Some physics experiments have become famous to posterity because the solution introduced whole new realms of inquiry. Generally, the researchers at the time didn't even realize when performing the work that the question they were looking into was such an important one

PHYSICS

Question: What Is Physics?

Answer:

Physics is the scientific study of matter and energy and how they interact with each other.

This energy can take the form of motion, light, electricity, radiation, gravity . . . just about anything, honestly. Physics deals with matter on scales ranging from sub-atomic particles (i.e. the particles that make up the atom and the particles that make up those particles) to stars and even entire galaxies.

How Physics Works

As an experimental science, physics utilizes the scientific method to formulate and test hypotheses that are based on observation of the natural world. The goal of physics is to use the results of these experiments to formulate scientific laws, usually expressed in the language of mathematics, which can then be used to predict other phenomena.

The Role of Physics in Science

In a broader sense, physics can be seen as the most fundamental of the natural sciences. Chemistry, for example, can be viewed as a complex application of physics, as it focuses on the interaction of energy and matter in chemical systems. We also know that biology is, at its heart, an application of chemical properties in living things, which means that it is also, ultimately, ruled by the physical laws.

Major Concepts in Physics

Because physics covers so much area, it is divided into several specific fields of study, such as electronics, quantum physics, astronomy, and biophysics.
