Physics: an exciting science

 

                                      Physics is very interesting

 because as a physicist you research the laws by which nature operates. Unlike biologists or chemists, physicists deal with inanimate nature that does not change physically. Physics is the most fundamental science upon which all other natural sciences are based. Not only is the behavior of matter in space and time examined, but the structure of space and time itself is also investigated.

                                         Physics is a diverse science   

The term "physics" comes from the Greek and means something like "natural science". Even the ancient philosophers of Greece thought about nature.

                                            ? How do physicists speak

 The language of physics is mathematics, because physical phenomena are widespread throughout the world and are very likely to be the same in the entire universe everywhere and can be described in the same way everywhere - that is, mathematically. So physicists talk "mathematically" and the articles they use to write are theories around the world. But it also means that things that cannot be described mathematically, cannot be explained physically: for example love, the beauty of an image, or human consciousness. Science in the physical sense can do a lot, but by no means everything.

                                                         theory and practice

 Physics can be roughly divided into two areas: theoretical and experimental physics. Experimental physicists conduct practical research using machines and devices to ask specific questions about nature. The results of the experiment are the answer. For example, Galileo Galilei dropped various objects from the Leaning Tower of Pisa to determine when they fell. On the other hand, theoretical physicists talk to each other in the language of mathematics. They talk about certain theories and what follows. However, sometimes the results of these conversations have to be verified by experiments, because they want to talk purposefully about the world and not about things that are just false dreams.

At the beginning of the twentieth century, Einstein's theory of relativity (better: "consistency theory") was very theoretical, and many conclusions could not be verified empirically at that time. Today we have very accurate clocks and very fast computers at our disposal and experiments can be derived from pure theory and theoretical examination, theory and practice eventually go hand in hand.

Physicists study not only the smallest thing in the world, the nucleus of an atom and its components, but also the largest that exists: the universe or the universe. Physicists who deal with stars are called astrophysicists, and those who deal with the formation of the universe are called cosmologists. Here, too, physicists often reach their limits, because if you wanted to check what exactly happened during the Big Bang, the previous theories don't give any meaningful answers. Meanwhile, physicists are interested in questions such as: "What was before the Big Bang?" or "Does the universe repeat itself?" , which were previously considered religious questions.

Physics is everywhere There are physical processes to be investigated everywhere, which is why there are trends such as biophysics, astrophysics or physical chemistry. Anyone who wants to become a physicist today has good career prospects; In many fields they are very much in search of - it is always exciting to engage with the essence of nature and create practical things.
