“doubt is the father of invention” what do you think the statement means and whether you agree with this idea

Galileo Galilei once said, “Doubt is the father of invention”. Thus we can say that, doubt is one of the factors which can influence the expansion of knowledge. For me I believe doubt sometimes tends to call on reason and somehow encourages people to hesitate before acting or belief. Thus we can say that doubt is the key to knowledge where with the feeling of doubt, people feel uncertain on something and try as possible they can in order to falsify and find the certainty.”Nathan Salmon (1995) proposes that a believer has a grasp of a proposition and has attempted consciously to choose between the proposition and its negation.” [2] From these definition we can claim that, by doubt it actually can triggers the feel of unbelief and then, from this , the knowledge of something will be invented when further investigation is conduct. I believe the words ‘key to knowledge’ from the phrase is refer to ability of doubt which can triggers and progress to an understanding on something.

Science subjects either Natural Science or Human Science are the possible area of knowledge which follows a pattern in the growth of knowledge with the presence of uncertainty beyond any suspicion. In Natural Science area, yes, I believe presence of doubt is the key to knowledge. For example, in atomic model theory, Bohr state that electrons in atom move in shells around the nucleus which contains protons. But since he invent it, many scientists feels doubt with the law and try to argue and invent new law by the improvement of scientific revolutionary as they feel uncertain towards Bohr’s result. For example, in Quantum Physical Models of atom, many scientist try to explain the concept in better way like Erwin Schrodinger who are fascinated by this idea and approach the spectral phenomena that Bohr’s failed to explain. [3] James Chadwick also feel something is lack towards the model .He search for unanswered questions related to it. So he found Bohr’s atomic model cannot be apply as new theory that can be proven to work with the newly acquired knowledge. He proved the existence of neutrons, the neutral particles in nucleus. This shows that doubt aids us in the search for new knowledge, as the idea of absolute certainty lead to more questions revolving around it.
