What kind of physics are there

As such, it is a huge and diverse area of study. In order to make sense of it, scientists have focused 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.

Physics is sometimes broken into two broad categories, based on the history of the science: Classical Physics, which includes studies that arose from the Renaissance to the beginning of the 20th century; and Modern Physics , which includes those studies which have been begun since that period.

Part of the division might be considered scale: modern physics focuses on tinier particles, more precise measurements, and broader laws that affect how we continue to study and understand the way the world works. Another way to divide physics is applied or experimental physics basically, the practical uses of materials versus theoretical physics the building of overarching laws as to how the universe works. As you read through the different forms of physics, 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. Before the turn of the 19th century, physics concentrated on the study of mechanics, light, sound and wave motion, heat and thermodynamics, and electromagnetism.

Classical physics fields that were studied before and continue to develop and be taught today include:. Later, in , Einstein presented a general theory of relativity in which the definition of gravitation was also explained. Cosmology and Space Exploration: In this branch the study of the origin, structure and the movement of various celestial bodies of the world is studied. In the space exploration, the launch and the study of man-made or artificial satellites and the information received from them is also analyzed and studied.

Mesoscopic physics deals with materials of an intermediate length in a sub discipline condensed matter. The scale of these materials can be described as being between the nano scale size of a quantity of atoms such as a molecule and of materials measuring micrometres.

Therefore, we can say that Physics is a fundamental science whose rules are used in all the technologies and all other branches of science. Also, it had helped human beings in understanding the philosophical side of life by successfully interpreting many mysteries of the world. Important facts about Motion.

The world runs on energy, so nuclear physics is a great choice for anyone looking to learn more about how the world works. Named after the nucleus of the atom, the skills you learn on this degree can help you to work in a variety of industries, including the environment and medicine.

Quantum physics is apparent in every form of science from chemistry to biology, and even computing. After completing an undergraduate degree in physics, there are plenty of options for your next step.

One route is to continue your academic adventure with a postgraduate degree. This is the perfect opportunity to find an even more detailed specialism for you to spend your time on. There are different forms of postgraduate study for you to choose from. Your first step would be to undertake a Masters degree. You can stop there and enter the world of work, or continue your studies with a PhD — which is an excellent choice if you want to work in innovation and research.

If you decide to enter the graduate employment market straight after your undergraduate degree, there are many opportunities waiting for you.

There are a whole range of different specialisms for you to work in, based on your interests and degree choice. Studying physics at university means you will learn a variety of transferable skills. Studying physics at a UK university is an excellent choice for international students. This will be beneficial for you as it shows you have the level of English required to work across the world, as English is commonly used as a universal language between teams of multiple nationalities.

The technologies of our modern society throughout the world are related to physics. For example, a car is made on the principle of mechanics and a refrigerator is based on the principles of thermodynamics. In our daily life, we hardly find a device in which laws of physics are not involved.

It is the study of the motion of objects, their causes, and their effects. Sub branches of mechanics are:. It is the study of the nature of heat, modes of transfer , and effects of heat. It is the study of physical aspects of sound waves , their production, properties, and applications. It is the study of physical aspects of light, its properties, and the use of optical instruments.
