Editor’s Note: This article is a part of the series Understanding Natural Phenomena.
The birth of our universe, namely the Big Bang, is described by scientists as a ‘quantum event’. What does that mean?
All natural phenomena are governed by the laws of quantum mechanics. However, much of our day-to-day activity and experience can be well-explained in terms of the laws of classical mechanics, propounded, among others, by Newton. Classical mechanics is a good approximation (but only an approximation) of quantum mechanics under certain conditions. Newton’s three laws of motion are examples of laws of classical mechanics.
