A ball bouncing back on an impact to the ground, a straw whistling like flute, a helium balloon rising against the gravity, a force called gravity pulling everything towards the surface of Earth. So many different, direct and related events like these that take place together in our lives remain unnoticed. They are so serpentine in nature that they all wind up around few set principles laid down by the branch of science known as Physics.
Unless one is a trained physicist, he may not be able to appreciate the importance and dependence of our lives on Physics. The most astonishing fact about this particular subject is that, though, the set of basic laws, principles or equations are very few; they govern the working of all the objects at macro level (Classical Mechanics) as well as the the objects at the micro level (Quantum Mechanics) throughout the Universe.
Few most common things which are very essential for daily lives are based upon the principles set by this canopy of science and these may be listed in brief, as follows:
It is a very common phenomenon that may be observed daily in our lives. When air is passed through one end of the straw leaving that particular opening partially closed, it results in production of different sounds. The reason behind this sound is that a vibration is produced due to the inflow of air which sets up waves in the air in the straw causing the vibrations to bounce back and forth between the two ends of the straw.
One may never think that there is a whole branch of physics i.e. Acoustics, that deals particularly with the physics behind sound.
Physics is absolutely the epitome of all the sciences when it comes to anything that we use for energy. Even the extraction of oil which is used as a fuel to provide energy is accomplished by the use of some other energy which in turn is processed using different energy based upon the principles of physics.
Its also essential in the research and implementation of clearner and more environment friendly energy sources. Everything, starting from the mechanically driven equipments to highly automated vehicles to the energy saving solar cars requires the basic thermodynamic laws for implementation.
A man with a basic sense of physics would always be grateful towards this subject by keeping the world in one’s hand in a very literal sense. The idea of internet draws back to the idea of creation of basic landline phones equipped at every home. It’s the electromagnetism and the quantum optics that is simply indispensable to nearly every aspect of the way we currently communicate.
The Bottom Line
The list is nevertheless endless and would wrap around it all the functions and cycles on this planet. All fancy houses, smartphones and the transport systems in its essence and implementation is based upon the study of physics.
