MODERN ELECTRON THEORY
Previously, to define electricity, several theories were developed through experiments and by observing its behaviour. Among them, the well-explained theory was ‘Modern Electron Theory of Matter’. This theory was developed based on the research works of the famous scientists Sir William Crooks, J. J. Thomson, Robert A. Milliken, Sir Earnest Rutherford, and Neils Bohr. According…

ELECTRICITY
The invisible energy that constitutes the flow of electrons in a closed circuit to do work is called ‘electricity’. It is a form of energy that can be easily converted to any other form. Previously, it was thought that electricity is a matter which flows through the circuit to do work. However, now it has…

INTRODUCTION
Electricity plays an important role in our day-to-day life, and hence, we should be aware of the various functions that electricity can perform. It is mainly used for lighting (lamps), heating (heaters), cooling (refrigerators), entertainment (radio and TV), transportation (electric traction), calculations (calculators), etc. Nowadays, all our basic needs are completely dependent upon electricity. Hence, it…

Applications of Acoustics
Acoustics is a vast branch of science that finds its application in almost every field. Some of the prominent applications of acoustics are:
-
Types of Acoustics
Environmental Noise Environmental acoustics is concerned with vibration and noise caused by roadways. Railways, aircraft and general activities that are related to the environment. The main goal of these is to reduce vibration and noise that affects the environment. Musical Acoustics Musical acoustics is concerned with the study of physics of music i.e., how sounds…

What Is Acoustic Energy?
Acoustic energy can be defined as the disturbance of energy which passes through matter in the form of a wave. In other words, it is the energy concerning the mechanical vibrations from its components is called acoustic energy. Any acoustic event has the following stages. The process in which some other form of energy is…

What Is Acoustics?
The branch of physics that is concerned with the study of sound is known as acoustics. We can define acoustics as, The science that deals with the study of sound and its production, transmission, and effects. A scientist or researcher who studies acoustics is called an Acoustician and someone working in the field of acoustics…

History
The origin of aerospace engineering can be traced back to the aviation pioneers around the late 19th to early 20th centuries, although the work of Sir George Cayley dates from the last decade of the 18th to the mid-19th century. One of the most important people in the history of aeronautics[8] and a pioneer in aeronautical engineering,[9] Cayley is…

Branches of aerospace engineering
The aerospace engineer is armed with an extensive background suitable for employment in most positions traditionally occupied by mechanical engineers as well as limited positions in the other various engineering disciplines. The transportation, construction, communication, and energy industries provide the most opportunities for non-aerospace applications. Because land and sea vehicles are designed for optimum speed and efficiency, the aerospace engineer…
