how can science makes life easy?

Technology makes life easy, especially innovation.

The term innovation may refer to both radical and incremental changes in thinking, in things, in processes or in services (Mckeown, 2008). Invention that gets out in to the world is innovation. In many fields, something new must be substantially different to be innovative, not an insignificant change, e.g., in the arts, economics, business and government policy. In economics the change must increase value, customer value, or producer value. The goal of innovation is positive change, to make someone or something better. Innovation leading to increased productivity is the fundamental source of increasing wealth in an economy.

Innovation is an important topic in the study of economics, business, technology, sociology, and engineering. Colloquially, the word "innovation" is often used as synonymous with the output of the process. Since innovation is also considered a major driver of the economy, the factors that lead to innovation are also considered to be critical to policy makers.
