Answer 2

basic science principally refers to the scientific disciplines of Physics, Chemistry, Biology and Mathematics. The principal idea behind something being labelled as basic science is that study of basic science leads to a better understanding of natural phenomena. It looks for "knowledge and discovery of facts" to enable one to understand an already existing phenomenon. For instance, Botany teaches you how plants grow, how plants synthesize food, why their leaves are green etc. Physics teaches you why things fall, what produces light etc. Mathematics teaches you what numbers are and how they are evaluated, what equations are and how they are solved. Most of basic science related study does not look for an application that would benefit from it.
