Physics: Above Complex Theories and Mathematics

Physics is defined as the study of matter and radiation. Some define it as the oldest and the most basic pure science. Since physics is the most basic pure science, it is very difficult to understand. Even though it is difficult to understand, it is all around us, not in the sense that everything we use from needles to advanced space ships are dependent on the laws of physics. I am trying to explain how physics describes our behaviors and how it teaches us life lessons.

Physics is not just about answering questions like “Why does universe exists?” with complex theories and mathematics like quantum mechanics. Physics is also about explaining why we behave in certain way. For instance, let's take an atom, an atom consists of protons, electrons and neutrons. Proton are positively charged particles and they are inside of nucleus. Electrons are negatively charged particles and they are outside of nucleus. We can observe this phenomenon in our society too. The people with similar attitude are always together. The application of Bernoulli's Theorem makes the lifting of an aero-plane in the air possible. It also explains why everything, including human beings, tries to move from state of having high pressure to low one.

Not only does physics explain human behaviors, theories of physics can also be taken as important life lessons. Let's take Heisenberg's Uncertainty Principle. It states that the position and momentum of a particle cannot be determined simultaneously to any degree of accuracy.  This is not because of some limitation of our technology or mathematics; it is due to the property of quantum particles. If we take this analogy then we can learn that some time we are unable to do something and it is not necessarily our fault.

Physics explains (tries to explain) fundamental behavior of entire universe and it is applicable to intelligent life forms like ours. It teaches us many things and gives us hope. Physics is not just complex theories and even more complicated mathematics to explain the complex theory. It is fundamental explanation of why we do certain things in certain way. For a second change the angel of elevation and you can see how beautiful the world of physics really is.
