Define economics and explain?

Question

Define economics and explain?

Answer 1

I can still remember on the first lecture, my Macroeconomic professor told us: 'Economics, is the study of the allocation of scarce and limited resources, to fulfill humans' unlimited wants'

Answer 2

A COIN AND A BREAD--  HOW TO TRANSACT WITHOUT SACRIFICING  BOTH

Answer 3

I define economics as study of nature, composition, laws, properties and classification of wealth. In simple words I call it as chemistry of wealth. I love to study wealth the way chemist studies matter.

In my opinion economics is a pure material science. I know that my views are not palatable to economists.
