The subject has many scientific laws that are actually statements describing tested and confirmed phenomena. It has been around for a really long time. Physics covers almost everything from sound to light, nuclear science to geology and many more fields.
Quick Facts: –

- An atom is very small and most of it is empty space.
- An electron can move in straight lines as well as waves.
- If we talk about the quantum world then Past, Present and Future all three occur simultaneously there.
