Physics: What We Do and We Don’t Know

Abstract

This chapter pays little attention on how physics has given us a whole new point of view; physics behind a series of amazing facts. The definition of physics is not only associated with study of matter, energy and the interaction between them; but it is actually about to asking fundamental questions and try to answer them by observing and experimenting. This chapter includes few topics like: important ideas, legworks, important laws to remember, use of physics, role of physics and a theory of everything. This chapter also gives a look at what a world would be without physics.

Keywords: Amazing facts, atomic nucleus, conservation, cosmology, distance, dynamo, elementary particles, everyday life, fluctuation, general ideas, GRT, ideas, interaction, legworks, matter energy, microscopic scale, QFT, string theory, vibrational mode.
