How can I teach myself physics


Physics in school

You know them physics mostly as the really difficult subject, for which you need a bunch of incomprehensible mathematics. "Isn't it bad to get off there, is it?", Unfortunately, with this way of thinking, you are missing out on countless exciting insights. With your school knowledge alone you can explain countless things that happen around you. Physics is based on observing nature and finding an explanation for the observation.

History of physics

The natural science of physics developed from philosophy. Claims are still being made today and attempts are made to confirm or refute them. But today people trust experiments instead of arguments. The aim was and still is to understand the universe in its entirety and thus to be able to make predictions. With the researchers Galileo and Newton, physics took on its present form.

Classification of physics

Sub-areas of physics are: the mechanics, which deals with the movement of massive bodies that optics, which deals with light, but also with other electromagnetic waves and the Electricity, which deals with electrical charges and their effects. Magnetism also belongs to the theory of electricity.

Further sub-areas are the Acoustics, which deals with the sound waves, and the Thermodynamicswhich deals with the effects of a change in temperature.

There are also three sub-areas that deal with Structure and structure of matter employ: the Atomic physics, which deals with the structure of matter, the Nuclear physics, which deals with the structure of atomic nuclei and their interactions such as radioactivity and the astrophysicswhich deals with the explanation of our night sky.

There are countless topics that cannot be assigned to just one area.

Tools of physics

To really understand physics you have to Experimentation and evaluation. For the evaluations one then necessarily needs mathematics as a tool. In this way, one can also formulate generally applicable laws of nature from his results.
