Most of the production processes used for most of the products and services generated in the industry, and even in homes is the result of application of theories and principles of science.
For example, let us take the ubiquitous electricity. The knowledge electricity itself we have today is the result of efforts of science. The equipments we use for generate electricity like the modern turbines and generators also cannot be designed, manufactured or operated without modern scientific knowledge.
Within homes let us take the process of washing clothes, The process appears quite simple to us. But the shapes of various components that make the clothes move in different ways so that these are cleaned thoroughly, and the movement of these components has been designed based on very specialized scientific knowledge.
The humble knife you use in the kitchen is most probably made of steel that has been developed and manufactured based on very specialized scientific knowledge. Even the water that you get in your tap is transported from its source to your tap employing a complicated network of pipes, pumps and storage tanks, which have been designed using scientific knowledge of hydraulics. It between the water has been purified using a combination of processes such as filtration, flocculation, and chemical reactions. We need science to understand and use all such processes to use them to serve our needs.
As a matter of fact it will be difficult for us to find a modern production process in which science does not play an important role.
