Physics is perhaps the oldest natural science which was practised for centuries. It describes the entire physical realm and its most intricate behaviour on the macro, atomic, molecular, and planetary scales. It not only provides the fundamental theoretical bases for all other sciences but also helps to understand the underlying physical mechanisms of nature. As every scientist in this field knows well, it is an open door to a vast range of new and breakthrough understanding. However, due to the incredible complexity of the various laws involved, even the best existing theories and laws are subject to constant revision and improvement.
The term “physics” derives from “phrase” and “class.” Phrases like “virtual particles” or “time” refer to the concepts of empty space and time, while “laws” refers to the fundamental laws of governing interaction among matter and energy. A “law” is a well-established theory whose application is well-tested and can be tested, observed, or confirmed by observation. Laws of physics, as many of you might have heard, describe the behaviour of objects at various distances and temperatures. A number of such laws include the laws of electricity, magnetism, sound, nuclear fission and the big bang theory.
Another aspect of physics is “cautionary science”. This includes all those methods and techniques used in physics for controlling and interpreting natural phenomena. It includes such areas as astronomy, thermodynamics, and geology. All these aspects form a complex web, which is the subject of fundamental physics.
The subject of physics is a fascinating one. Physicists have come up with many theories in this field. Some of the more popular ones include Planck’s Constant, the Weak Field Theory, the Quantum Vacuum, and the Standard Model. These have been put forward as real physical phenomena, but there are also plenty of theories that they have not been able to prove. They have therefore had to undergo testing from various laboratories.
The Standard Model of Physics postulates a set of basic laws of nature, including the fine-structure constant, the strong force, and the weak nuclear force. Apart from these, there are a number of other physical phenomena that are believed to be the result of interacting particles. Among them are the electromagnetic radiation and the big bang theory. Apart from these, there are the electron and the nucleus, and the Higgs boson. In order to test the theories, experiments are performed using various methods such as particle colliders, satellite missions, and the detectors of the Large Hadron Collider (LHC).
Quantum mechanics and nuclear physics are related closely, as it describes how subatomic particles behave. It is also called ‘particle physics’ because it makes use of the predictions of the grand unified theory. Theories based on quantum mechanics state that every single event that can happen has a definite cause and effect. This means that we can predict with great accuracy what will happen in the near future, or even in the distant future.
String theory is one of the many branches of physics that have been explained by quantum mechanics. The String theory family of theories consists of ‘many-body’ theory, ‘closed-system’ theory, ‘flat physics’, and ‘boson’ theory. All these theories predict that our physical reality is highly correlated, that we inhabit multiple time and space at the same time, and that we live in a world governed by quantum gravity. String theory thus plays a major role in the study of cosmology and the search for a Theory of Everything.
The study of the properties of atoms and molecules is an important part of the Search for God. If the existence of a Creator and a universe without any outside factors is granted then the chances of finding life forms in the nearby universe are very high. Moreover, if the laws of science are correct then we can expect that similar laws govern the behavior of elementary particles. In fact, it was Alfred Nobel who made the first experiment to prove the theory of relativity. His experiment made use of two balloons whose diameter and height were established through weighing them.
