Physicists from Different Countries – Class 11 | Chapter – 1 | Physics Short Notes Series PDF for NEET & JEE
Physicists from Different Countries: Discovery and invention are two different words. Both the terms are often confusing because they sound like they are the same thing but in reality, these two words have completely different meanings. Discovery and Invention refer to bringing something new to light or shedding light on something new, respectively. Discovery and invention might allow us to better comprehend the fundamentals and their analogies.
What is Discovery?
Discovery refers to the process of finding out or uncovering something new, previously unknown or unseen, or previously unappreciated. It can refer to the discovery of a new scientific principle, the discovery of a new species of plant or animal, the discovery of a new artistic technique or genre, or the discovery of a new geographical location, among many other possibilities.
Discovery can be an intentional process, as when a scientist sets out to discover a new principle or a scholar sets out to discover a new text, or it can be accidental, as when a new species is found in the course of a routine survey, or a new artistic style is discovered through experimentation.
Discovery is a key aspect of human progress and creativity, and it is driven by curiosity, observation, and experimentation. It has been a powerful force in shaping human history and continues to play a critical role in advancing our understanding of the world and improving our lives.
What is Invention?
The invention is defined as the development of something new that never existed before by one’s effort, hard work, knowledge, ideas, experiments, and talents. In other words, the invention is the manufacture of something wholly new that has its applications and functions in the current world.
A person who develops or creates an invention is known as an inventor. The term “inventor” is derived from the Latin word which means “to find.” Although inventing is frequently connected with science and engineering, inventors are not always engineers or scientists.
There are numerous scientific discoveries that have significantly influenced the way we think and live throughout history. Discoveries not only improve our living standards but also help in the advancement of mankind like production of crop, medical applications etc.
